Therefore, the distance between Car A and Car B when they meet is 150 miles (distance from Fresno to Los Angeles) - 90 miles (distance covered by Car A) = 60 miles. Thus, they meet 60 miles away from Fresno, which is 200 miles away from Fresno along the entire route.

To determine the distance from Fresno where the cars meet, we need to consider the relative speeds and the time it takes for each car to travel. Car A starts in Sacramento and travels at a speed of 30 mph, while Car B starts in Los Angeles and travels at a speed of 75 mph.

Car A starts one hour earlier than Car B, so it has a head start. In that one hour, Car A would have traveled 30 miles (30 mph x 1 hour). The remaining distance between Car A and Fresno would be 400 miles - 30 miles = 370 miles.

Now, we need to calculate the time it takes for Car B to travel from Los Angeles to Fresno, which is 150 miles. Using the formula Time = Distance / Speed, the time taken by Car B would be 150 miles / 75 mph = 2 hours.

Since Car B starts at noon, it will take 2 hours to reach Fresno, which means it will arrive at Fresno at 2pm. At that time, Car A would have been traveling for 3 hours (11am to 2pm). Given that Car A's speed is 30 mph, it would have covered a distance of 30 mph x 3 hours = 90 miles.

Therefore, the distance between Car A and Car B when they meet is 150 miles (distance from Fresno to Los Angeles) - 90 miles (distance covered by Car A) = 60 miles. Thus, they meet 60 miles away from Fresno, which is 200 miles away from Fresno along the entire route.

Answer:

NOT 24/25 and NOT -4/5

Step-by-step explanation:

took the quiz

If cos(x) = 3/5 and sin x < 0, sin(2x) is equal to -24/25 as a fraction in simplest terms.

To find sin(2x), we can use the double-angle formula for sine:

sin(2x) = 2 * sin(x) * cos(x)

Given:

cos(x) = 3/5

sin(x) < 0

We need to determine sin(x) based on the given information.

Using the Pythagorean identity, sin^2(x) + cos^2(x) = 1:

\((sin(x))^2 + (cos(x))^2 = 1\\(sin(x))^2 + (3/5)^2 = 1\\(sin(x))^2 + 9/25 = 1\\(sin(x))^2 = 1 - 9/25\\(sin(x))^2 = 16/25\)

sin(x) = -4/5

Now we can  the values into the double-angle formula for sine:

sin(2x) = 2 * sin(x) * cos(x)

sin(2x) = 2 * (-4/5) * (3/5)

sin(2x) = (-8/5) * (3/5)

sin(2x) = -24/25

Therefore, sin(2x) is equal to -24/25 as a fraction in simplest terms.

Answer: The slope of the line is b. 3

Answer:b

Step-by-step explanation:

Answer:

\(=\frac{4x+12}{7y-28}\)

Step-by-step explanation:

Four times a number (let's call this x) is added to twelve. In other words, this is:

\(4x+12\)

Now, this entire thing is divided by seven times a different number (let's use y) minus twenty-eight. So:

\((4x+12)\div (7y-28)\)

Let's put it into a fraction to simplify. Remember that dividing something by something else is the same as putting it over fraction. Thus:

\(=\frac{4x+12}{7y-28}\)

And we're done!

Answer:

12 + 4x

7y - 28

Step-by-step explanation:

Here we have 4 times a number is added to 12. So let's say that number is "x". Now we have 4x plus the 12 to get 4x + 12 And that is divided by 7 times a different number minus 8.

So 7 times a different number "y" is the same as 7y and put in that minus 28 to get 7y - 28 and don't forget the dividing!

It'll end up being;

12 + 4x

7y - 28

The area to the right of 2.6 in a t-distribution with n degrees of freedom is 0.9082, assuming the sample is a random sample from a distribution that is reasonably normally distributed and that we are doing inference for a population mean.

We can use a t-distribution table or a statistical software program to find the area to the right of 2.6. Here, I'll show you how to use a t-distribution table:

Determine the degrees of freedom (df) for the t-distribution. This is equal to n - 1.

Look up the t-value that corresponds to a one-tailed probability of 0.05 and df.

Multiply the t-value by -1 to get the positive value for the right tail. In other words, we need the value for the right tail, so we flip the sign of the t-value.

Add 0.5 to the result to account for the area to the left of 2.6. This gives us the cumulative probability from negative infinity to 2.6.

Subtract the result from 1 to get the area to the right of 2.6.

For example, suppose we have a sample of size n = 10. Then, the degrees of freedom for the t-distribution would be df = 10 - 1 = 9. Using a t-distribution table, we can look up the t-value that corresponds to a one-tailed probability of 0.05 and df = 9:

t-value = 1.833

Since we need the positive value for the right tail, we multiply by -1 to get:

t-value = -1.833

Adding 0.5 to account for the left tail gives:

t-value + 0.5 = -1.333

Finally, subtracting this result from 1 gives us the area to the right of 2.6:

Area to the right of 2.6 = 1 - 0.0918 = 0.9082

Step-by-step explanation:

The integral of 9cos(θ) with respect to theta is 9sin(θ) + C.

We start with the integral of 9cos(θ) with respect to θ:

∫ 9cos(θ) dθ

To integrate cos(θ), we can use the trigonometric identity:

∫ cos(θ) dθ = sin(θ) + C

where C is the constant of integration.

Now, we have the integral in the form:

∫ 9cos(θ) dθ

Since 9 is a constant, we can pull it out of the integral:

9∫ cos(θ) dθ

Now, we can substitute the integral of cos(θ) with sin(θ):

9sin(θ) + C

Therefore, the integral of 9cos(θ) with respect to θ is given by:

∫ 9cos(θ) dθ = 9sin(θ) + C

In this expression, 9sin(θ) represents the antiderivative of 9cos(θ), and C represents the constant of integration. The constant of integration arises because when we take the derivative of a constant, it becomes zero. Therefore, when we perform an indefinite integral, we add a constant term to account for all possible functions that have the same derivative.

Given \(a\), half the length of the major axis, and \(b\), half the length of the minor axis for an ellipse, its eccentricity is \(\displaystyle e=\sqrt{1-\frac{b^2}{a^2}}\), which tells us how close the ellipse is to the shape of a circle or how flat and round it is. An infinitely long ellipse would have an infinitely long major axis, so the greater the \(a\) value, the eccentricity gets infinitely closer to 1.

The probability of a bulb lasting for between 557 and 561 hours is roughly 0.0382 or 3.82%

Able to utilize the standard ordinary dissemination to discover the likelihood of a bulb enduring for between 557 and 561 hours. To do this, we ought to standardize the values utilizing the equation:

z = (x - μ) / σ

where x is the bulb lifetime we're fascinated by

, μ is the cruel(mean) lifetime,

and σ is the standard deviation.

For 557 hours:

z1 = (557 - 530) / 15 = 1.8

For 561 hours:

z2 = (561 - 530) / 15 = 2.07

Employing a standard ordinary conveyance table or a calculator with a typical dissemination work, we are able to discover the probabilities corresponding to these z-scores:

P(z1 < Z < z2) = P(1.8 < Z < 2.07)

This speaks to the likelihood of a bulb enduring between 557 and 561 hours, where Z could be a standard ordinary variable.

Employing a standard ordinary dispersion table or a calculator, we discover:

P(1.8 < Z < 2.07) ≈ 0.0382

Therefore, the likelihood of a bulb enduring for between 557 and 561 hours is roughly 0.0382 or 3.82% (adjusted to four decimal places).

A. To determine whether the variances are equal, conduct a right-tail test using appropriate statistical methods.

B. To test the equality of variances, we can use a right-tail test, also known as a folded test.

This test compares the variances of two samples to assess whether they are statistically different or not.

Here are the steps to conduct the right-tail test for equal variances:

1. State the null and alternative hypotheses:

  - Null hypothesis (H0): The variances of the two samples are equal.

  - Alternative hypothesis (H1): The variances of the two samples are not equal.

2. Choose an appropriate significance level (e.g., α = 0.05) to determine the critical value.

3. Calculate the test statistic.

There are different tests available, such as the F-test or Bartlett's test, depending on the nature of the data and assumptions.

The test statistic measures the ratio of the variances and follows a specific distribution under the null hypothesis.

4. Determine the critical value corresponding to the chosen significance level.

This critical value helps determine whether to reject or fail to reject the null hypothesis.

5. Compare the test statistic with the critical value.

If the test statistic exceeds the critical value, we reject the null hypothesis, indicating that the variances are significantly different.

If the test statistic does not exceed the critical value, we fail to reject the null hypothesis, suggesting that there is not enough evidence to conclude a significant difference in variances.

By following these steps and conducting the appropriate test, you can determine whether the variances of the samples are equal or not.
