The probability that a randomly selected student plays basketball, given that they run track is 0.38.

The possibility of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability.

Assume that events A and B are two independent occurrences with probabilities P(A) and P(B), respectively, such that the probability that event B will occur given that event A is given by: P(B|A) = P(A∩B)/P (A)

Given:

Percentage of the students who play basketball, P(A) = 31%

Percentage of the students who run track, P(B)= 29%

Percentage of the students who participate in both sports, P(A∩B) = 11%

The probability that a randomly selected student plays basketball, given that they run track is:

P(A|B) = P(A∩B)/P(B)

          = 11/29

          = 0.38

Answer:

A quadrilateral is a parallelogram if and only if opposite angles are equal.

So, to make the quadrilateral a parallelogram, we can set the following equalities:

(4x + 13) deg = (5x - 12) deg

(4y + 7) deg = (3x - 8) deg

Solving the first equation,

4x + 13 = 5x - 12

x = -5

Solving the second equation,

4y + 7 = 3(-5) - 8

4y + 7 = -17

4y = -24

y = -6

So, the values of x and y that make the quadrilateral a parallelogram are x = -5 and y = -6

The circumference of a circle is the distance encircling its edge. The length measured through the centre of a circle is its diameter. The radius of a circle is the distance from the centre to any point on the edge. The diameter and radius are identical in size, or 2r=d2 r=d.

Circumference =2×227×21=132 cm. Q.

Another way to think about the circle's circumference curve is to look at its 360-degree arc. As a result, a circle's diameter is equal to its 360-degree arc's length.

(a) Circumference of the circle = 2πr

= 2 × 22/7 × 14 cm

= 2 × 22 × 2 cm

= 88 cm

(b) Circumference of the circle = 2πr

= 2 × 22/7 × 28 mm

= 2 × 22 × 4 mm

= 176 mm

© Circumference of the circle = 2πr

= 2 × 22/7 × 21 cm

= 2 × 22 × 3 cm

= 132 cm

Therefore, 176 mm and 132 cm is the circumference of a circle.

The probability that Onex will have an EBIT that is below $0 is 0.38%. The correct answer is C.

The first step in solving this problem is to calculate the z-score, which is a measure of how many standard deviations a value is from the mean. In this case, the mean EBIT is $240,000, and the standard deviation is $90,000.

To find the z-score for an EBIT of $0, we subtract the mean from the value and divide by the standard deviation as follows:

This gives us a z-score of -2.67. Next, we use Table V, which is a table of standard normal distribution values, to find the probability that a value with a z-score of -2.67 will fall below 0. The probability is 0.38%, which means there is a very low chance that Onex's EBIT will be below $0.

Simple interest is p15612.12 and compound interest is p16500.If I was were Mr. henry ,I will choose offer of 2%.

1.To calculate simple interest, multiply the principal (initial amount) by the number of years, the interest rate, and the interest rate.

Contrarily, compound interest is computed by first adding the interest from earlier periods to the principal, and then computing the interest for the subsequent period on the updated sum.

Consider Mr. Henry investing P150,000 in ABC Bank at an annual simple interest rate of 2%:

Year 1: Interest earned is P3,000 (P150,000 x 2%).

Year 2: Interest earned is P3,000 ($150,000 x 2%).

Year 3: Interest earned is P3,000 ($150,000 x 2%).

Year 4: Interest earned is P3,000 ($150,000 x 2%).

Year 5: Interest earned is P3,000 ($150,000 x 2%).

Interest earned overall: P15,000

After five years, the total will be P150,000 plus P15,000, or P165,000.

Let's imagine Mr. Henry makes a P150,000 investment in Union Bank at a 2% yearly compound rate:

Year 1: P150,000 multiplied by 2% yielded P3,000 in interest, for a total of P153,000.

Year 2: P153,000 multiplied by 2% to be P3,060 in interest, for a total of P156,060.

Year 3: P156,060 multiplied by 2% to equal P3,121.20 in interest, for a total of P159,181.20.

Year 4: P159,181.20 multiplied by 2% yielded P3,183.624 in interest, for a total of P162,364.824.

Year 5: P162,364.824 multiplied by 2% yields P3,247.29696 in interest, for a total of P165,612.12096.

Interest earned in whole was P15,612.12096.

2 .If I were Mr. Henry, I would pick the 2% compounded annual offer from Union Bank. This is so that after five years, the total sum will be larger due to compound interest. Compound interest increases the amount on which interest is computed in the following period by adding the interest from prior periods to the principal. Due to this, the interest earned during the subsequent period will increase, and so on. As a result, after a certain amount of time, interest accrues more quickly and the overall amount is higher.

  Therefore , simple interest is p15612.12 and compound interest is p16500.If I was were Mr. henry ,I will choose offer of 2% .

What is isosceles triangles ?

An isosceles triangle is a triangle with two sides of equal length. These two sides are called the legs and they are congruent. The third side is called the base and it is not necessarily congruent to the legs. The angle opposite to the base is called the vertex angle.

To solve for x, we can start by isolating x on one side of the equation.

We can do this by subtracting x^2 from both sides ,

x^2 - x^2 = 2x-25 - x^2

we get 0 = 2x - 25 - x^2

Now we can add x^2 to both sides ,

x^2 = 2x - 25

Now we can move the -25 to the other side of the equation ,

x^2 - 2x + 25 = 0

Now we can factor the left side of the equation ,

(x-5)(x-5) = 0

Now we can solve for x by setting each factor equal to zero ,

x-5 = 0 , x = 5

Answer: Based on the histogram, it is not possible to determine the exact number of people who travel more than 30 miles to work. However, we can estimate the number of people by using the histogram.

Step-by-step explanation: The histogram shows the frequency density of people traveling different distances to work.

The Y-axis shows the frequency density, and the X-axis shows the distance in miles.

The histogram is divided into bars, each representing a range of distances.

We can see that the majority of people travel less than 30 miles to work, with the highest frequency density being around 20 miles.

However, the histogram does not provide the exact number of people for each bar. Therefore, we cannot determine the exact number of people who travel more than 30 miles to work.

b) Sam travels around 20 miles to work.

Explanation:

205 people out of 550 people is approximately 37% of the total number of people surveyed.

The closest bar on the histogram to 37% is the one around 20 miles.

Therefore, it can be estimated that the distance that Sam travels is around 20 miles.

Weight of second load = 8000 pounds

There are 2000 pounds (lb) in one US customary ton (t). Both tons and pounds are measurements of mass/weight in the US customary and imperial systems of measurement. However, the definitions of the ton vary in both systems. For example, there are 2240 pounds in an imperial ton, and 2204.6226 pounds in a metric ton.

The US ton is mostly used in the United States and Canada. The imperial ton was mostly used in the UK, and still is to a degree, but since the UK began the process of metrication, the metric ton is also used in the UK.

Convert pounds to tons:

1 pound = 0.0005 ton

8000 pounds = 4 ton

Then,

Weight of second load = 4 ton

Total weight of the gravel, in tons = Weight of first load + Weight of second load

x - 9y = 10 ( add 9y to both sides )

x = 9y + 10 → (1)

3y² = 4x + 7 → (2)

substitute x = 9y + 10 into (2)

3y² = 4(9y + 10) + 7

3y² = 36y + 40 + 7

3y² = 36y + 47 ( subtract 36y + 47 from both sides )

3y² - 36y - 47 = 0 ← as required

(b)

solving using the method of completing the square

add 47 to both sides

3y² - 36y = 47 ← factor out 3 from each term in the left side

3(y² - 12y) = 47

to complete the square on the left

add/subtract ( half the coefficient of the y- term)² to y² - 12y

3(y² + 2(- 6)y + 36 - 36) = 47

3(y - 6)² - 3(36) = 47

3(y - 6)² - 108 = 47 ( add 108 to both sides )

3(y - 6)² = 155 ( divide both sides by 3 )

(y - 6)² = [tex]\frac{155}{3}[/tex] ( take square root of both sides )

y - 6 = ± [tex]\sqrt{\frac{155}{3} }[/tex] ≈ ± 7.2 ( to 1 decimal place )

add 6 to both sides

y = 6 ± 7.2

then

y = 6 - 7.2 = - 1.2

y = 6 + 7.2 = 13.2

substitute these values into ( 1) for corresponding values of x

x = - 1.2 : x = 9(- 1.2) + 10 = - 10.8 + 10 = - 0.8 ⇒ (- 1.2, - 0.8 )

x = 13.2 : x = 9(13.2) + 10 = 118.8 + 10 = 128.8 ⇒ (13.2, 128.8 )

Answer:

  (x, y) ≈ (-0.7, -1.2) or (128.7, 13.2)

Step-by-step explanation:

You want the solution to the simultaneous equations ...

Solving the first equation for x, we can substitute into the second equation to get a quadratic in y.

  x = 9y +10 . . . . . . . add 9y to the first equation

  3y² = 4(9y +10) +7 . . . . . substitute for x

  3y² = 36y +47 . . . . . . . eliminate parentheses

  3y² -36y -47 = 0 . . . . subtract the right-side expression

The equation can be written in vertex form as ...

  3y² -36y = 47

  3(y² -12y +36) = 47 +3(36)

  3(y -6)² = 155

  y -6 = ±√(155/3)

  y = 6 ± (√465)/3 ≈ -1.19, 13.19

  x = 9y +10 ≈ -0.69, 128.69
