We have to find the equation of a line fo which we know two points, using the point-slope form.

The point-slope let us write the equation of the line knowing the value of the slope m and the coordinates of one point (x0,y0) of the line:

We use the two known points to calculate the slope m:

Using the point (-1,7), we can write the equation as:

Answer: From the options, the right ones are:

y-7=-1(x-(-1))

y-4=-1(x-2) --> this one would have been used if we picked the point (2,4) instead of (-1,7)

y=-x+6

the 90% confidence interval for y when x = 69 is (41.5, 52.3). This means that we are 90% confident that the true value of y is between 41.5 and 52.3 when x = 69.

To find the 90% confidence interval for y when x = 69, we need to use regression analysis. First, we need to fit a regression model to the data and obtain the regression equation. Once we have the regression equation, we can plug in the value of x = 69 and get the predicted value of y.

Assuming that we have already performed the regression analysis, let's say the regression equation is:

y = 4.5 + 0.6x

To find the predicted value of y when x = 69, we simply plug in x = 69 into the equation:

y = 4.5 + 0.6(69)
y = 46.9

So, the predicted value of y when x = 69 is 46.9.

To find the 90% confidence interval for this predicted value, we need to use the standard error of the estimate (SEE) and the t-distribution. The formula for the confidence interval is:

y ± t(0.05/2, n-2) x SEE

where y is the predicted value of y, t(0.05/2, n-2) is the critical value of the t-distribution for a 90% confidence level with n-2 degrees of freedom (n is the sample size), and SEE is the standard error of the estimate.

Let's say that the SEE is 3.2 (we obtain this value from the regression output) and the sample size is n = 50. Using a t-distribution table, we find that the critical value for t(0.05/2, 48) is 1.677.

Plugging in the values, we get:

46.9 ± 1.677 x 3.2
46.9 ± 5.4
(41.5, 52.3)

So, the 90% confidence interval for y when x = 69 is (41.5, 52.3). This means that we are 90% confident that the true value of y is between 41.5 and 52.3 when x = 69.
To provide a 90% confidence interval for y when x = 69, we need more information such as the regression equation, the standard error, and the critical value. Once you have this information, you can calculate the lower and upper bounds of the confidence interval. Please provide the necessary details, and I'll be happy to help you find the 90% confidence interval.

True. With a sample size of 100 and a p of .5, the sampling distribution of the sample proportion will approximate a normal distribution.

This is because of the central limit theorem, which states that with a sufficiently large sample size, the sampling distribution of the sample proportion will approach a normal distribution regardless of the shape of the population distribution.

The central limit theorem is an important concept in statistics that allows us to make inferences about population parameters based on sample statistics. It states that with a large enough sample size, the sampling distribution of the sample mean or proportion will approximate a normal distribution, even if the underlying population distribution is not normal. In this case, with a sample size of 100 and a p of .5, we have a sufficiently large sample size to apply the central limit theorem and approximate a normal distribution. Conclusion: In conclusion, the statement that the sampling distribution of the sample proportion will approximate a normal distribution with a sample size of 100 and a p of .5 is true. The central limit theorem is a powerful tool that allows us to make inferences about population parameters with confidence, even if the underlying population distribution is not known.

The measure of angle Z is 47.19°.

Law of sines is defined as that ratio of the length of the sides of a triangle to the sine of the angle opposite to the these sides are equal.

That is, if a, b and c are sides opposite to the angles A, B and C respectively, then,

a / sin A = b / sin B = c / sin C

Given a triangle XYZ.

m ∠Y = 78°, XY = 9, XZ = 12

We have to find the measure of angle Z.

Using the law of sines,

XZ / sin Y = XY / sin Z

12 / sin (78°) = 9 / sin Z

Cross multiplying,

12 × sin Z = 9 × sin (78°)

sin Z = (9 × sin (78°)) / 12

sin Z = 0.7336

Z = sin⁻¹ (0.7336)

Z = 0.8236 radians

The standard form of the equation is 8x+5y = -20.

What is standard form of the equation?

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5. When an equation is given in this format, finding both intercepts is rather simple (x and y). Additionally, when resolving systems of two linear equations, this form is highly helpful.

Here the given equation is

=> \(\frac{1}{2}y=\frac{-4}{5}x-2\)

=> \(\frac{1}{2}y=\frac{-4x-10}{5}\)

=> 5y = 2(-4x-10)

=> 5y = -8x-20

=> 8x+5y = -20.

Hence the standard form of the equation is 8x+5y = -20.

To prove the statement "If 7x > 56, then x > 8" indirectly, we assume the opposite of the desired conclusion and show that it leads to a contradiction.

Assume that 7x > 56 but x ≤ 8. We will show that this assumption leads to a contradiction.

Since x ≤ 8, multiplying both sides of the inequality by 7 (which is a positive number) gives us:

7x ≤ 7 * 8

7x ≤ 56

However, this contradicts the initial assumption that 7x > 56. If 7x ≤ 56, then it cannot be simultaneously true that 7x > 56.

Since our assumption led to a contradiction, we conclude that the opposite of our assumption must be true. Therefore, if 7x > 56, then x > 8. This completes the indirect proof.

We'll need 2 points so we'll choose (-6, 0) and (0, -3).  

Let's calculate the slope (or 'm') using

Slope or m = (Y2 -Y1) ÷ (X2 -X1)

Slope ('m') = (-3 -0) / (0, - -6) = -3 / 6 = -1/2

Then we calculate the equation using:

(y - y1) = m • (x -x1)

(y - 0) = -1/2 * (x - -6)

y = -1/2 x -3

Step-by-step explanation:

Answer:

Step-by-step explanation:

X-intercept:  (-6, 0)

Y-intercept:  (0, -3)    ⇒   b = -3

Slope:   \(m=\dfrac{y_2-y_1}{x_2-x_1}\)

\(m=\dfrac{0+3}{-6+0}=-\dfrac12\)

Slope-intercept form  y = mx + b

\(y=-\frac12x-3\)        {multiply both sides by 2}

2y = - x - 6          {add x to both sides}

x + 2y = - 6

Step-by-step explanation:

If Tommy has 12 cars and it's 5 more than Billy

You do the inverse of addition which is Subtraction

12 - 5 = 7

In Detail:

a = Billy (Answer)

b = +5 (more or less / difference)

c = Tommy (12)

a + b = c

a + 5 = 12

Now you find out something that when you add 5 to it makes 12

You can do this by bringing the +5 to the 12 but you have to change it to a -5

So:

a + 5 = 12 turns to a = 12 -5

12 - 5 = a

7 = 12 - 5 or 12 - 5 = 7

The distribution of the given function is a uniform distribution.

A strictly increasing function is the one which increases continuously in a given interval. If f-1(u) is a strictly increasing function of u, then the distribution of f-1(u) is the same as that of u. This is because a strictly increasing function preserves the rank ordering of its input, so if u-1 and u-2 are two random variables with a uniform distribution on the interval (0,1), then the rank order of f-1(u-1) and f-1(u-2) will be the same as the rank order of u-1 and u-2. Since the uniform distribution is defined by the rank order of its values, this means that the distribution of f-1(u) is also uniform on the interval (0,1).

The specific heat of the given sample is approximately 239.6 J/(kg·°C). This value indicates the amount of heat energy required to raise the temperature of 1 kilogram of the sample by 1 degree Celsius.

To determine the specific heat of the given sample, we can use the formula Q = mcΔT, where Q is the heat energy added, m is the mass of the sample, c is the specific heat, and ΔT is the change in temperature. By rearranging the formula, we can solve for c.

In this case, we are given the heat energy Q = 1.25 × 10^4 J, the mass m = 28.4 N (weight in newtons), and the change in temperature ΔT = 18.0 °C. To calculate the specific heat c, we rearrange the formula Q = mcΔT and solve for c.

First, we convert the weight from newtons to kilograms by dividing it by the acceleration due to gravity (9.8 m/s^2). So, the mass of the sample in kilograms is 28.4 N / 9.8 m/s^2 = 2.90 kg.

Substituting the given values into the formula, we have 1.25 × 10^4 J = c × 2.90 kg × 18.0 °C. Now, we can solve for c by dividing both sides of the equation by (2.90 kg × 18.0 °C):

c = (1.25 × 10^4 J) / (2.90 kg × 18.0 °C) ≈ 239.6 J/(kg·°C).

The expression 24 - 2x is suitable for the length of the garden as it accounts for the width and represents the remaining length of fencing available for the garden.

To enclose a rectangular garden, three sides need to be fenced, while one side is already adjacent to Mr. Picasso's house. The remaining three sides will consist of two equal lengths for the width and one length for the length of the garden.

Since the total length of fencing available is 24 ft, the width requires two equal sides, each of length x ft, which amounts to 2x ft. Subtracting this width from the total length of fencing gives us 24 - 2x ft, which represents the remaining length available for the length of the garden.

The proportion of 12-ounce bags that contain more than the advertised 12 ounces of chips is 0.

The proportion of 12-ounce bags that contain more than the advertised 12 ounces of chips can be determined by finding the area under the normal distribution curve to the right of the mean.

To find this proportion, we can use the z-score formula:
z = (x - mean) / standard deviation

In this case, we want to find the proportion of bags that contain more than 12 ounces, so x = 12 ounces.

z = (12 - 12.5) / 0.2
z = -2.5 / 0.2
z = -12.5

Next, we need to find the cumulative probability associated with the z-score. We can use a standard normal distribution table or a calculator to find this probability.

Looking up the z-score of -12.5 in the table or using a calculator, we find that the cumulative probability is approximately 0.

Therefore, the proportion of 12-ounce bags that contain more than the advertised 12 ounces of chips is 0.
