Answer:

B.y = 4x+19

Step-by-step explanation:

We are given a point and a slope, we can write the equation in point slope form

y-y1 = m (x-x1)

y--1 = 4(x--5)

y+1 = 4(x+5)

We want the equation in slope intercept form(y=mx+b)

Distribute

y+1 =4x+20

Subtract 1 from each side

y+1-1 = 4x+20-1

y = 4x+19

$\huge{\boxed{\text{B.}\ y=4x+19}}$

Point-slope form is $y-y_1=m(x-x_1)$ , where $m$ is the slope and $(x_1, y_1)$ is a point on the line.

Substitute the values. $y-(-1)=4(x-(-5))$

Simplify the negative subtraction. $y+1=4(x+5)$

Distribute the $4$ . $y+1=4x+20$

Subtract $1$ on both sides. $\boxed{y=4x+19}$

The owner of a local golf course wants to estimate the difference between the scores of golfers on his golf course and the score

Olenka [21]

Answer:

(8) The correct option is (3).

(2) The correct option is (1).

Step-by-step explanation:

(8)

The hypothesis can be defined as:

H₀: There is no difference between the two population means, i.e. μ₁ = μ₂.

Hₐ: There is a difference between the two population means, i.e. μ₁ ≠ μ₂.

The decision rule of the test based on confidence interval is:

If the (1 - α) % confidence interval consists the null hypothesis value then the null hypothesis is not rejected. and vice-versa.

The 90% confidence interval for the paired difference between means is, (-3.31, 14.74).

The interval consists the null value, 0.

Thus, the null hypothesis was failed to be rejected.

Conclusion:

No significant difference exists between the average difference in scores and the differences were calculated as 0.

Thus, the correct option is (3).

(2)

A (1 - α) % confidence interval implies that there is (1 - α) % chance of the population parameter to be contained in this interval.

Or if 100 such intervals are constructed then (1 - α) of these intervals will consist the true parameter value.

The 99% confidence interval for the difference between means is, (-0.124, 13.85).

This interval implies that the true mean difference between the two populations lies in this interval with probability 0.99.

Conclusion:

We are 99% confident that the difference between the average age of all men and all women who play golf at the course is between -0.124 and 13.85.

Thus, the correct option is (1).

Answer:

Step-by-step explanation:

Isabell, can you see that the sides are 2x6 each? each half of the triangle will make a total rectangle of 2x6 or 12 square meters

there are 4 of those so 48 sq meters plus the base of 4x4 or 16 sq meters

48+16 = 64 square meters total

If you drew a marble from a bag containing 24 marbles and you had a 1/3 probability of drawing a red marble, how many red marble

Masja [62]

Hello there.

Question: If you drew a marble from a bag containing 24 marbles and you had a 1/3 probability of drawing a red marble, How many red marbles are in the bag?

Answer: 1/3 is just a simplified version of the original fraction.
To find this out, get the denominator to the total of 24.
24 / 3 = 8.
You multiply the bottom by 8 therefore you need to do the same to the top.

In short, Your answer is $\frac{8}{24}$ .
The number of red marbles is 8.

Hope This Helps You!
Good Luck Studying ^-^
