Find the following probability, given the number of trials and the probability of obtaining a success. Round your answer to four decimal places. P(X≥8) , n=9 , p=0. 8

Answers

Answer 1

The probability of getting 8 or more successes in 9 trials, with given success rate in each trial is 0.8, is 0.9520.

To find the probability , we can use the cumulative distribution function (CDF) of the binomial distribution:

P(X ≥ 8) = 1 - P(X < 8) = 1 - P(X ≤ 7)

Using a binomial calculator or a binomial probability distribution table, we can find:

P(X ≤ 7) = 0.0480 (rounded to four decimal places)

Therefore,

P(X ≥ 8) = 1 - 0.0480 = 0.9520

So the probability of getting 8 or more successes in 9 trials, given the probability of success in each trial is 0.8, is 0.9520 (rounded to four decimal places).

This solution satisfies both constraints, as x + y = 4 + 8 = 12, which is less than or equal to 12, and 15x + 10y = 15 * 4 + 10 * 8 = 120, which is greater than or equal to 140.

What is inequality?

In mathematics, a relationship between two expressions or values that are not equal to each other is called 'inequality. ' So, a lack of balance results in inequality.

We can write the first inequality as x + y <= 12

This inequality represents the constraint that Mav can work at most 12 hours in total between both jobs.

The second inequality represents the constraint that Mav must earn no less than $140 in a given week, which can be written as:

15x + 10y >= 140

To graph the system of inequalities, we can plot the lines corresponding to x + y = 12 and 15x + 10y = 140 on the coordinate plane and shade the region that satisfies both inequalities.

The solution to the system of inequalities will be the values of x and y that lie in the shaded region.

One possible solution is x = 4 and y = 8, which means that Mav works 4 hours of lifeguarding and 8 hours of landscaping in a given week, earning a total of 15 * 4 + 10 * 8 = $120.

Hence, This solution satisfies both constraints, as x + y = 4 + 8 = 12, which is less than or equal to 12, and 15x + 10y = 15 * 4 + 10 * 8 = 120, which is greater than or equal to 140.

Answer:

y ≤ 12 -xy ≥ 14 -1.5x(x, y) = (4, 8) — 4 hours lifeguarding, 8 hours landscaping

Step-by-step explanation:

You want inequalities, their graph, and a possible solution satisfying Mav's requirement for at most 12 total hours spent lifeguarding at $15 per hour and landscaping at $10 per hour, with an income of at least $140.

Setup

The required relations can be written ...

  x + y ≤ 12 . . . . . . . total hours

  15x +10y ≥ 140 . . . . total earnings

Inequalities

The inequalities need to be solved for y to match the answer format requirements.

  inequality 1: y ≤ 12 -x . . . . . . . . . . subtract x

  inequality 2: y ≥ 14 -1.5x . . . . . . divide by 10, subtract 1.5x

Solution

The attached graph shows a couple of possible solutions. The solution space is the doubly-shaded area bounded by vertices ...

  (4, 8), (12, 0), and (9 1/3, 0)

Mav will make the most money working 12 hours lifeguarding (x, y) = (12, 0).

She can just meet her income requirements by working 8 hours lifeguarding and 2 hours landscaping (x, y) = (8, 2).

One possible solution is 4 hours lifeguarding and 8 hours landscaping.

In a survey of 20 sophomores at a high school, 8 students said that they would prefer a class field trip to an amusement park, rather than a museum. The sophomore class has 150 students. Predict the number of sophomores who prefer a class trip to an amusement park.

Answers

Answer:

60 sopomores

Step-by-step explanation:

Let X denote the event prefer amusement park on a field trip

The probability that a sophomore will opt for a class trip to an amusement park would be 8/20 = 2/5 based on survey results

P(X) = 2/5

Based on this probability, if the number of sophomores is 150 then expected number of sophomores who prefer the amusement park trip

E(X) - P(X) x N where N is the total number of sophomores

E(X) = 2/5 x 150 = 60

Part 1 Enter an expression that represents the area of Mary's new garden. An expression that represents the area is Part 2 out of 2 Evaluate the expression if the side length of Mary's original garden was 9 feet. The area of Mary's new garden is square feet

Answers

Part 1: If Mary doubles the area of her original square garden, the expression that represents the area of Mary's new garden is 2x^2.

Part 2: If the side length of Mary's original garden is 9 feet, the area of Mary's new garden is 162 square feet.

Part 1: If Mary doubles the area of her original square garden, the new area of her garden will be 2 times the area of her original garden.

If the area of her original garden is x^2, then the area of her new garden will be:

2(x^2) = 2x^2

So, the expression that represents the area of Mary's new garden is 2x^2.

Part 2: If the side length of Mary's original garden is 9 feet, then the area of her original garden is:

x^2 = (9 feet)^2 = 81 square feet

To find the area of Mary's new garden, we can substitute 81 for x^2 in the expression we found in Part 1:

2x^2 = 2(81 square feet) = 162 square feet

So, the area of Mary's new garden is 162 square feet.

Answers

If Sam drives 6.25 miles to visit his mother every 0.048 minutes, and then drives 83.9 miles to visit his friend, he will have 8.45 miles left in his gas tank when he reaches his destination. If Mia correctly answers one problem every 0.048 minutes, she can correctly answer 62.5 problems in 3 minutes.
A. If Sam drives 60.25 miles to visit his mother and 83.9 miles to visit his friend, the total distance he will drive is 60.25 + 83.9 = 144.15 miles.

To find out how many miles he has left until his gas tank is empty, we subtract the total distance he will drive from the amount of gas left in his tank:

178.8 - 144.15 = 34.65 miles

So Sam will have 34.65 miles left until his gas tank is empty.

B. To find out how many problems Mia can correctly answer in 3 minutes, we first need to find out how many problems she can correctly answer in 1 minute. Let's call this "p".

We know that she correctly answers one problem for every 0.048 minutes, so in 1 minute, she can answer 1 / 0.048 = 20.83 problems.

To find out how many problems she can correctly answer in 3 minutes, we simply multiply the number of problems she can answer in 1 minute by 3:

3 * 20.83 = 62.5 problems

So Mia can correctly answer 62.5 problems in 3 minutes.

What is m∠B?

There is a seven sided polygon ABCDEFG in which the measure of angle BCD is 148 degrees, the measure of angle DEF is 142 degrees, the measure of angle EFG is 130 degrees, the measure of angle FGA is 129 degrees, and the measure of angle GAB is 120 degrees. Angle CDE is a right angle.

Answers

For the polygon ABCDEFG, the measurement of ∠B is option D: 141°.

What is a polygon?

In a two-dimensional plane, a polygon is a closed object formed of line segments rather than curves. Polygon is a word that combines the words poly (which meaning numerous) and gon (means sides).

The polygon ABCDEFG has angle measurements as -

Measurement of ∠BCD = 148°

Measurement of ∠DEF = 142°

Measurement of ∠EFG = 130°

Measurement of ∠FGA = 129°

Measurement of ∠GAB = 120°

Measurement of ∠CDE = 90°

Let the measurement of ∠ABC be x° .

In a heptagon (or polygon having seven sides) the sum of all angles is 900°.

So, for polygon ABCDEFG the equation will be -

∠BCD + ∠CDE + ∠DEF + ∠EFG + ∠FGA + ∠GAB + ∠ABC = 900°

Substitute the values in the equation -

148° + 90° + 142° + 130° + 129° + 120° + x = 900°

148° + 90° + 142° + 130° + 129° + 120° + x = 900°

759° + x = 900°

x = 900° - 759°

x = 141°

Therefore, the value of x is obtained as 141°.

Solve the right triangle table

Answers

The measure of the angle m∠B is equal to 41°. Using the sine rule the lengths of a and b are 9.6 and 8.3 respectively.

What is the sine rule

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

We shall first evaluate for the angle m∠B as follows:

m∠A + m∠B + m∠C = 180° {sum of interior angles of a triangle}

49° + B + 90° = 180°

B + 139° = 180°

B = 180° - 139° {subtract 139° from both sides}

m∠B = 41°

12.7/sin90° = a/sin41

a = (12.7 × sin49)/sin90° {cross multiplication}

a = 9.5848

12.7/sin90° = b/sin49

b = (12.7 × sin49)/sin90 {cross multiplication}

b = 8.3319

Therefore, the measure of the angle m∠B is equal to 41°. Using the sine rule the lengths of a and b are 9.6 and 8.3 respectively.

What is the circumference of a circle with a diameter of 11 inches? (use 22/7 for pi)

Answers

The circumference of a circle with a diameter of 11 inches using  π as 22/7 is 34.86 inches.

To find the circumference of a circle, we can use the formula:

C = πd

where C is the circumference, π is a mathematical constant (approximately 22/7), and d is the diameter of the circle.

The diameter of a circle is a straight line that passes through the center of the circle and touches two points on the edge of the circle. In this problem, we are given that the diameter of the circle is 11 inches.

To find the circumference, we can substitute this value for d in the formula:

C = πd = π(11 inches)

We can simplify this by using the approximation π ≈ 3.14 (or more precisely, π ≈ 22/7), to get:

C ≈ (3.14)(11 inches) = 34.54 inches

or

C ≈ (22/7)(11 inches) = 34.86 inches

So the circumference of the circle is approximately 34.54 inches or 34.86 inches, depending on which approximation of π is used.

A cylinder's surface area is the area that its surface takes up in three dimensions. A three-dimensional structure known as a cylinder has circular bases that are parallel to one another. There are no vertices on it. Area of three-dimensional shapes often refers to surface area. Square units are used to denote the surface area. Examples include cm2, m2, and so forth. A group of circular discs placed on top of one another might be thought of as a cylinder. The cylinder has both surface area and volume since it is a solid with a three-dimensional geometry.

The area of the cylinder is determined by adding the areas of its two circular bases and curving surface.

The Surface Area of Cylinder = Curved Surface + Area of Circular bases

each of two persons tosses three fair coins. what is the probablity they obtain same number of heads

Answers

The probability of obtaining the same number of heads is 3/8 or 0.375 when each of two persons tosses three fair coins.

The probability that two persons will obtain the same number of heads depends on the number of possible combinations of heads and tails that can be obtained by each person.

Since each coin flip results in either a heads or tails, there are 2 possible outcomes for each flip. Therefore, for three coin flips,

there are 2^3 or 8 possible combinations of heads and tails.

Out of these 8 combinations, there are 3 in which both persons have the same number of heads (i.e., 0 heads, 1 head, or 3 heads).

So, the probability of obtaining the same number of heads is 3/8 or 0.375.

1. A worm moves down a path that is 1,3 m long. The worm starts moving at 9h12 and reaches the end of the path at 9h24. How fast is the worm travelling?​

Answers

The worm is travelling at a speed of 0.0018 meter per second.

What is Speed?

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Given that,

Total distance travelled by the worm = 1.3 m

The worm starts moving at 9 hour 12 minutes and reaches the end of the path at 9 hour 24 minutes.

Total time taken = 24 - 12 = 12 minutes

Speed = Distance / Time

Speed = 1.3 / 12

           = 0.1083 meter / minute

           = 0.0018 meter per second

Hence speed of the worm is 0.0018 meter per second.

What is FG?
pls help this is hard

Answers

Answer:

FG = 18

Explanation:

There is a simpler solution:

It has to do with the interior angle bisector theorem. (the illustration with the angle marks and the line show that it is being bisected)

Which will divide the opposite side into segments whose lengths have the same ratio as the adjacent sides of the bisected angle.

x / 24 = x + 10 / 54 →

54x = 24(x + 10) →

54x = 24x + 240 →

30x = 240 →

x = 8.

Since the expression x + 10 represents the length of FG, it's length must be 18.

in a train yard there are tank cars, boxcars, and flatcars. how many ways can a train be made up consisting of tank cars, boxcars, and flatcars? (in this case, order is not important.)

Answers

There are 55 ways to form a train consisting of tank cars, boxcars, and flatcars by using concept of combinations.

If there are t tank cars, b boxcars, and f flatcars in the train yard, then the number of ways to form a train by selecting some of these cars is the same as the number of ways to distribute n = t + b + f identical objects into three distinct boxes, such that each box may receive any number of objects (including zero). The solution is given by the combination formula:

C(n + k - 1, k - 1)

where k is the number of boxes (in this case, k = 3). Therefore, the number of ways to form a train from t tank cars, b boxcars, and f flatcars is:

C(t + b + f + 3 - 1, 3 - 1) = C(t + b + f + 2, 2) = (t + b + f + 2)! / ((t + b + f)! * 2!)

There are 4 tank cars, 3 boxcars, and 2 flatcars in the train yard, then the number of ways to form a train is:

C(4 + 3 + 2 + 2, 2) = C(11, 2) = 55

What is the average rate of change of the function -4≤x≤0

Answers

Answer:

The average rate of change of a function over an interval is a measure of how the function's value changes over that interval, given by the ratio of the change in the function's value to the change in the independent variable. To find the average rate of change of a function over an interval, we need to know the function's values at two points in the interval.

In the case of the function f(x) = x^2, the interval is -4 ≤ x ≤ 0. To find the average rate of change, we need to find the difference in the function's value between two points in this interval, and divide that by the difference in the x-values.

For example, if we compare the values of the function at x = -4 and x = 0, we have:

f(-4) = (-4)^2 = 16

f(0) = 0^2 = 0

The difference in the function's value is f(0) - f(-4) = 0 - 16 = -16.

The difference in the x-values is x2 - x1 = 0 - (-4) = 4.

So the average rate of change over this interval is the difference in the function's value divided by the difference in the x-values, or -16 / 4 = -4.

In other words, the average rate of change of the function f(x) = x^2 over the interval -4 ≤ x ≤ 0 is -4, meaning that for every 4 units of change in x, the function value decreases by 16 units.

If one marble is drawn from a bag containing three red ones and one white one , then probability that it is a red one is 3/4 .

Total number of marbles in the jar is = 4 marbles ;

the number of red marbles in the jar is = 3 marbles ;

the number of white marbles in the jar is =  1 marble ;

The probability of drawing a red marble from the jar can be calculated as the number of red marbles divided by the total number of marbles in the jar:

⇒ P(red marble) = number of red marbles / total number of marbles

Answers

The equation -6(x+1)+8x=2(x-3) has all real numbers as solutions, meaning that any value of x will make the equation true. The equation does not have a single unique solution for x.

What is the equation in one variable?

An equation in one variable is a mathematical expression that contains a single variable, typically represented by x. The goal of solving an equation in one variable is to determine the value of the variable that makes the equation true.

To solve the equation -6(x+1)+8x=2(x-3), we can simplify the left-hand and right-hand sides of the equation and then solve for x. Here are the steps:

Distribute the -6 and 2 to the terms inside the parentheses: -6x - 6 + 8x = 2x - 6

Combine like terms on each side of the equation: 2x - 6 = 2x - 6

Subtract 2x from both sides of the equation: -6 = -6

At this point, we have a true statement (-6 = -6), but there is no variable present. This means that the equation has infinitely many solutions, and every real number is a solution to the equation.

Hence, the equation -6(x+1)+8x=2(x-3) has all real numbers as solutions, meaning that any value of x will make the equation true. The equation does not have a single unique solution for x.

Answers

The hypotenuse of the right triangle with legs measuring 18 in and 26 in is 31.6 in, rounded to the nearest tenth. This is calculated by using the Pythagorean Theorem, which states that a2 + b2 = c2 and plugging in the values for a and b.

The hypotenuse of a right triangle is the longest side of the triangle and is always opposite of the right angle. To calculate the length of the hypotenuse, you need to use the Pythagorean Theorem. The theorem states that a2 + b2 = c2, where a and b are the legs of the triangle and c is the hypotenuse. In this case, a is 18 inches and b is 26 inches, so the equation would be 182 + 262 = c2. Plugging in the values, we get 324 + 676 = c2, which simplifies to 1000 = c2. To find the length of the hypotenuse, we need to take the square root of 1000, which is 31.6 inches. Rounded to the nearest tenth, the hypotenuse of the right triangle with legs measuring 18 in and 26 in is 31.6 in.
