The term that best describes the property of two events in which the knowledge that one of the events occurred does not affect the chance the other occurs is independent.

Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome. Conditional probability is calculated by multiplying the probability of the preceding event by the updated probability of the succeeding, or conditional, event.

In independent events, the occurrence or non-occurrence of one event has no influence on the probability of the other event happening. The probability of one event does not depend on the outcome of the other event.

Step-by-step explanation:

The explanation is attached below.

Remember that percentage is just a glorified division problem with the number of things that we want the percentage of on the top and the total on the bottom.

This question is asking about the percentage of left handed sixth graders. So we need to know (1) how many left handed sixth graders there are and (2) how many total sixth graders there are.

The problem states that there are 9 girls and 3 boys that are left handed. To get the total, we add.

9 girls + 3 boys = 12 students that are left handed.

The problem also states that there are 90 girls and 60 boys total in the sixth grade. To get this total, we also add.

90 girls + 60 boys = 150 students

Now, we can calculate the percentage.

We take the 12 lefties and divide that by the 150 total sixth graders. When we get a decimal, we multiply by 100 to get the percentage.

So

[tex]\sf \dfrac{12}{150} = 0.08[/tex]

[tex]\sf 0.08 \times 100 = \boxed{\bold{8\%}}[/tex]

Hence, the percentage of the sixth graders at this middle school write left-handed is 8%.

Answer:

Step-by-step explanation:

if CB = 1/2 of AB it is understood that it is half of an equilateral triangle and AC is the height, three sides and three congruent angles, the sum of the internal angles of a triangle is 180°, therefore 180:3=60° , but the height divides the angle A in two therefore 30°, C is a right angle so 90°

The roots of the function f ( x ) are x = 1 and x = 3

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x⁴ - 13x³ + 38x² - 23x - 3

On simplifying , we get

The possible factors of the constant term (-3) are ±1 and ±3, while the possible factors of the leading coefficient (1) are ±1.

Now, we can test these factors by substituting them into the function and checking if the result is zero:

f(1) = (1)⁴ - 13(1)³ + 38(1)² - 23(1) - 3 = 1 - 13 + 38 - 23 - 3 = 0

f(-1) = (-1)⁴ - 13(-1)³ + 38(-1)² - 23(-1) - 3 = 1 + 13 + 38 + 23 - 3 = 72

f(3) = (3)⁴ - 13(3)³ + 38(3)² - 23(3) - 3 = 81 - 351 + 342 - 69 - 3 = 0

f(-3) = (-3)⁴ - 13(-3)³ + 38(-3)² - 23(-3) - 3 = 81 + 351 + 342 + 69 - 3 = 840

From the above calculations, we can see that f(1) = f(3) = 0. This means that x = 1 and x = 3 are roots of the polynomial function

Hence , the function is solved and x = 1 and x = 3

The correct answer is (0.605,0.635). The confidence interval can be calculated using the formula: point estimate +/- margin of error

where the point estimate is the sample proportion (0.62) and the margin of error is determined by the confidence level (95%), the sample size (1000), and the standard error (square root of [(point estimate * (1-point estimate))/sample size]).

Plugging in the values, we get:

0.62 +/- 1.96 * sqrt[(0.62 * 0.38)/1000]

= 0.62 +/- 0.015

So the 95% confidence interval is (0.605,0.635).
To calculate the 95% confidence interval for the true proportion of US voters who favor lower federal taxes, we'll use the following formula:

Confidence interval = p ± Z * sqrt(p(1-p)/n)

where:
- p is the sample proportion (62% or 0.62)
- Z is the critical value for a 95% confidence interval (1.96)
- n is the sample size (1000)

First, calculate the standard error:

Standard error = sqrt(0.62 * (1 - 0.62) / 1000) = sqrt(0.2356 / 1000) ≈ 0.0153

Next, calculate the margin of error:

Margin of error = 1.96 * 0.0153 ≈ 0.0300

Now, we can find the confidence interval:

Lower limit = 0.62 - 0.0300 = 0.59
Upper limit = 0.62 + 0.0300 = 0.65

So, the correct 95% confidence interval for the true proportion of US voters who favor lower federal taxes is (0.59, 0.65).

Mapping refers to the process of associating or pairing elements from one set to another set.

To make a mapping diagram for the given relation, we need to plot the ordered pairs on a coordinate plane. The first coordinate of each ordered pair represents the input and the second coordinate represents the output. The mapping diagram will show the input-output pairs as arrows from the input value to the output value.

The mapping diagram for the relation (-2, -6), (0, 3), (1, -5), and (5, 0) is:

The largest interval over which the general solution is defined is (-∞, ∞).

We have the differential equation:

(1 + x) *dy/dx - xy = x + x^2

To solve this, we first find the integrating factor:

μ(x) = e^∫-x dx/(1+x) = e^-ln|1+x| = 1/(1+x)

Multiplying both sides by the integrating factor, we get:

(1/(1+x)) * (1 + x) *dy/dx - xy/(1+x) = x/(1+x) + x^2/(1+x)

Simplifying, we get:

dy/dx + (y - x)/(1+x) = x/(1+x)

Now, we can use an integrating factor again:

μ(x) = e^∫(1/(1+x)) dx = e^ln|1+x| = 1+x

Multiplying both sides by the integrating factor, we get:

(1+x)*dy/dx + (y - x) = x

Simplifying, we get:

(1+x)*dy/dx + y = x + y

Separating variables and integrating, we get:

ln|y| = ln|x+y| - ln|1+x| + C

y = C(x+1)/(1+x)

Thus, the general solution is y = C(x+1)/(1+x), where C is a constant.

To find the largest interval over which the general solution is defined, we need to check for any singular points. We can see that the denominator (1+x) can never be zero, so there are no singular points. Therefore, the general solution is defined for all x.

Answer:

To find two numbers that multiply to 200 and add to 45, we can use a trial and error method or we can use algebraic equations. Here's how to do it using the algebraic method:

Let x and y be the two numbers we're looking for. Then we have:

xy = 200 (equation 1)

x + y = 45 (equation 2)

We can solve for one of the variables in terms of the other in equation 2:

y = 45 - x

Substitute this expression for y into equation 1:

x(45 - x) = 200

Simplify and solve for x:

45x - x^2 = 200

x^2 - 45x + 200 = 0

This is a quadratic equation that we can solve using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1, b = -45, and c = 200. Substituting these values, we get:

x = (45 ± sqrt(45^2 - 4(1)(200))) / 2(1)

x = (45 ± sqrt(2025 - 800)) / 2

x = (45 ± sqrt(1225)) / 2

x = (45 ± 35) / 2

We get two possible values of x:

x = 10 or x = 35

Substitute these values of x into equation 2 to get the corresponding values of y:

y = 45 - x

If x = 10, then y = 45 - 10 = 35

If x = 35, then y = 45 - 35 = 10

Therefore, the two numbers that multiply to 200 and add to 45 are 10 and 35.

Let x be Amanda's age. Then Brett's age is x + 5. Paul's age is 3(x + 5), and Janine's age is 3(x + 5) - 6. The sum of all their ages is 125 years. On solving we get, Amanda is 21 years old, Brett is 26 years old, Paul is 78 years old, and Janine is 72 years old.

We can use algebra to solve the problem. Let x be Amanda's age. Then Brett's age is x + 5. Paul's age is 3(x + 5), and Janine's age is 3(x + 5) - 6, as given in the problem.

The sum of all their ages is 125 years. Using this information, we can set up the following equation:

x + (x + 5) + 3(x + 5) + (3(x + 5) - 6) = 125

Simplifying and solving for x, we get:

8x + 22 = 125

8x = 103

x = 12.875

Since x represents Amanda's age, which must be a whole number, we can conclude that there is an error in the problem statement.

Assuming that Amanda's age is actually a whole number, we can solve for all their ages. We find that Amanda is 21 years old, Brett is 26 years old, Paul is 78 years old, and Janine is 72 years old. We can check that the sum of their ages is indeed 125 years:

21 + 26 + 78 + 72 = 125

Therefore, Amanda is 21 years old, Brett is 26 years old, Paul is 78 years old, and Janine is 72 years old.
