BRAINLIEST FOR THE CORRECT AWNSER! The slope of the line below is –3. Use the coordinates of the labeled point to find a point-slope equation of the line.

Answer:

405

Step-by-step explanation:

Don't be confused about setting up the proportion. White has to go with white which is 4 and brown goes with 5.

The total is 9.

so proportion will look like this.

4/9 = 180/x          Cross Multiply

Before I solve this, notice that the white data is on top of the fraction, and the total is on the bottom of the fraction on either side of the proportion.

4x = 180 * 9

4x = 1620

x = 1620 / 4

x = 4 0 5

Notice that the brown is going to be bigger than the white but not by much

White                            180

Brown       405 - 180 = 225

Total                              405

The correct test statistic for this hypothesis test is 3.21 or 0.2617

To determine the appropriate test statistic for this hypothesis test, we need to first state the null and alternative hypotheses.

In this case, the null hypothesis is that the population mean height of adult women is equal to 63 inches, while the alternative hypothesis is that the population mean height is greater than 63 inches.

Next, we can use the formula for a t-test to calculate the test statistic:

t = (sample mean - hypothesized mean)/(sample standard deviation/sqrt(sample size))

Plugging in the given values, we get:

t = (64.2 - 63)/(2.9√40) = 3.21 or 0.2617

Therefore, the correct test statistic for this hypothesis test is 3.21. or 0.2617

To determine whether this test statistic is statistically significant, we would need to compare it to a critical value from the t-distribution with 39 degrees of freedom (since we have a sample size of 40 and are estimating one parameter, the population mean). If the test statistic is greater than the critical value, we can reject the null hypothesis and conclude that the population mean height of adult women is greater than 63 inches at a given level of significance.

In summary, the correct test statistic for this hypothesis test is 3.21. To determine whether this test statistic is statistically significant, we would need to compare it to a critical value from the t-distribution with 39 degrees of freedom.

The features of the function are given as follows:

Horizontal asymptote: y = 5.

Vertical asymptote: x = 2.

x-intercept: No x-intercept.

y-intercept: (0,-5).

Hole: No holes.

The horizontal asymptote is the limit of f(x) as x goes to infinity. To obtain this limit, we consider only the terms with the highest exponent of the numerator and of the denominator, hence:

here, we have,

g(x) = -5x/x -> y = 5 is the horizontal asymptote.

The vertical asymptote is the value of x for which the function is not defined, hence it is the zero of the denominator, thus:

x - 2 = 0 -> x = 2.

The x-intercept is the point (x,0), in which x is found when y = 0, hence:

-5x + 10 = 0

-5x = -10

5x = 10

x = 2.

However, the function is not defined at x = 2, meaning that it has no x-intercept.

The y-intercept is the value of y when x = 0, hence:

y = 10/-2 = -5.

The coordinates are (0,-5).

The entire function can be simplified as follows:

(-5x + 10)/(x - 2) = [-5(x - 2)]/(x - 2) = -5.

Meaning that the function has no holes.

The statement that the mean ± 1.96 standard deviations will include approximately 95% of the observations is in line with the empirical rule. This rule provides a rough estimate of the proportion of observations within a certain number of standard deviations from the mean in a normal distribution. In the case of ±1.96 standard deviations, it captures about 95% of the data.

For the normal distribution, the mean ± 1.96 standard deviations will include approximately 95% of the observations.

This is based on the empirical rule, also known as the 68-95-99.7 rule, which states that for a normal distribution:

- Approximately 68% of the observations fall within one standard deviation of the mean.

- Approximately 95% of the observations fall within two standard deviations of the mean.

- Approximately 99.7% of the observations fall within three standard deviations of the mean.

Since ±1.96 standard deviations captures two standard deviations on either side of the mean, it covers approximately 95% of the observations, leaving only about 5% of the observations outside this range.

Therefore, about 95% of the observations will be included within the range of the mean ± 1.96 standard deviations.

To find the critical T-value for a 99% confidence interval with a sample size of 45, we need to enter the degrees of freedom (df = n-1 = 44) and the confidence level (CL = 99%) into the T-distribution Inverse Calculator applet. This gives us a T-value of 2.691.

To construct the 99% confidence interval, we use the formula:

x¯ ± T × s/√n

where x¯ is the sample mean (768.2 lb), s is the sample standard deviation (15.1 lb), n is the sample size (45), and T is the critical T-value (2.691). Plugging in these values, we get:

768.2 ± 2.691 × 15.1/√45

which simplifies to:

(755.2, 781.2)

Therefore, the lower bound of the 99% confidence interval is 755.2 lb (rounded to two decimal places) and the upper bound is 781.2 lb (also rounded to two decimal places).

Increasing the confidence level typically increases the margin of error. This is because a higher confidence level requires a wider interval to capture a larger proportion of possible sample means.
To construct a 99% confidence interval for the mean breaking weight of the steel cables using the given sample, we'll need to find the critical T-value. For a sample of 45 cables, the degrees of freedom (df) is 44 (n-1). Using a T-distribution Inverse Calculator with a 99% confidence level and 44 degrees of freedom, we find the critical T-value to be approximately 2.69.

Now, we can compute the margin of error:
Margin of Error = T-value * (s/√n) = 2.69 * (15.1/√45) ≈ 6.03

The 99% confidence interval is then calculated as follows:
Lower Bound: x- Margin of Error = 768.2 - 6.03 ≈ 762.17
Upper Bound: x + Margin of Error = 768.2 + 6.03 ≈ 774.23

So, the 99% confidence interval is (762.17, 774.23).

In general, increasing the confidence level increases the margin of error, as we need a wider interval to be more confident that it contains the true population mean.

An initial-value problem is a type of boundary-value problem in mathematics, particularly in the field of differential equations.

The given initial-value problem is a separable differential equation, which can be written as:

dy/dt = -2(t + 1)y²

Integrating both sides, we get:

(1/y) = t² + 2t  + C

where C is the constant of integration.

Since we have an initial condition, we can use it to find the value of C:

y(0) = -1/15
C = -1/15

Solving for C, we get:

C = -1/15

So, the solution to the differential equation is:

(1/y) = t² + 2t -1/15

y = 1 / (t² + 2t -1/15)

The solution is defined for all t ≠ -1, since y = 0 is not defined. So, the largest interval on which the solution is defined is (-∞, -1) ∪ (-1, ∞). The interval notation for the largest interval is (-∞, -1) U (-1, ∞).

Answer:

The correct option is -

Yes, because the Expected value is 1 and not negative which would imply that there is a chance of winning.

Step-by-step explanation:

Given - A bag contains 10 blue marbles, 3 yellow marbles, and 12 orange marbles. If a blue marble is drawn you win $10. If a yellow marble is drawn you win $15. if an orange marble is drawn you lose $10. it cost $1 to play.

To find - Should you play the game?

Formula used -

Expected value , E[x] = ∑x p(x)

where p(x) is the probability.

Proof -

Given that,

Total blue marbles in a bag = 10

Total yellow marbles in a bag = 3

Total orange marbles in a bag = 12

So,

Total number of marbles in a bag = 10 + 3 + 12 = 25

Now,

Probability of getting blue marble = \(\frac{10}{25}\)

Probability of getting yellow marble = \(\frac{3}{25}\)

Probability of getting orange marble = \(\frac{12}{25}\)

So,

Expected value , E[x] = ∑x p(x)

                                   = (10)( \(\frac{10}{25}\)) + (15)(\(\frac{3}{25}\)) + (-10)(\(\frac{12}{25}\))

                                   = \(\frac{100}{25} + \frac{45}{25} - \frac{120}{25}\)

                                   = \(\frac{100 + 45 - 120}{25}\)

                                   = \(\frac{25}{25}\)

                                   = 1

So,

Expected value = 1

So,

The correct option is -

Yes, because the Expected value is 1 and not negative which would imply that there is a chance of winning.

Answer:

Multiply by the inverse.

Answer: 45

Step-by-step explanation:

(15)/(1/3) is the same thing as multiplying the top (numerator), by the inverse of the bottom (denominator).

So we have the following: \(\frac{15/1}{1/3}\)

Taking the inverse means flipping the fraction. The inverse of \(\frac{1}{3}\) is \(\frac{3}{1}\). So we can keep the top, and multiply by the inverse.

\(\frac{15}{1}\) X \(\frac{3}{1}\) = 15 x 3 = 45.

J = {-3, -2, -1}

J={x | x is an integer and -4 < x ≤ to -1}​

Integers are negative and positive whole numbers. This means that decimals will not be included in the set

From the set, x will start from integers greater than -4 but stop at -1.

The given set can be rewritten by listing as:

J = {-3, -2, -1}

The standard form is:

Convert each equation:

1. x² + 2x = -1                        add 1 to both sides

⇒ x² + 2x + 1 = 0

2. 4 + x² = 7x                        add - 7x to both sides and rearrange

⇒ x² - 7x + 4 = 0

3. x² - x = 1                            add - 1 to both sides

⇒ x² - x - 1 = 0

4. x² + 9x = 10                       add - 10 to both sides

⇒ x² + 9x - 10 = 0

5. 4x + 3 = x²                        add -4x - 3 to both sides

⇒ x² - 4x - 3 = 0

6. x² + 5x = 5                        add -5 to both sides

⇒ x² + 5x - 5 = 0

7. 2x² + 7x = 3                      add -3 to both sides

⇒ 2x² + 7x - 3 = 0

8. x² = 3x + 8                        add -3x - 8 to both sides

⇒ x² - 3x - 8 = 0

9. x(x + 3) = 1                         distribute and add - 1 to both sides

⇒ x² + 3x - 1 = 0

10. x² - 3x = -2                       add 2 to both sides

Answer:

71° F

Step-by-step explanation:

Consider the rational part of f(t)

\(\frac{40t^3}{t^3+100}\)  ( divide numerator and denominator by t³

= \(\frac{40}{1+\frac{100}{t^3} }\)

As t → infinity then \(\frac{100}{t^3}\) → 0 , the expression simplifies to

\(\frac{40}{1+0}\) = \(\frac{40}{1}\) = 40

Thus after driving for a long time

f(t) = 31 + 40 = 71° F

The number of students in the entire class is 40.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.

From the information given, when eating in the cafeteria at school, 65%, or 26, of the students in the class ate pizza.

Let the total number of people be illustrated as x.

This will be:

65% × x = 26

0.65x = 26

Divide

x = 26/0.65

x = 50
