Let's start by solving this equation using distribution method:

4(x - 3) = 2x + 7

4x - 12 = 2x + 7.

Move like terms on one side:

4x - 2x = 7 + 12

2x = 19

x = 9.5

Let's plug in x for 4x-3:

4x - 3

4 * 9.5 - 3

38 - 3

4x - 3 = 35

Answer:

Step-by-step explanation:

Step 1: Distribute

4(x - 3) = 2x + 7

4x - 12 = 2x + 7

Step 2: Add 12 to both sides

4x - 12 + 12 = 2x + 7 + 12

4x = 2x + 19

Step 3: Subtract 2x from both sides

4x - 2x = 2x + 19 - 2x

2x = 19

Step 4: Divide both sides by 2

2x / 2 = 19 / 2

x = 9.5

Step 5: Plug in 9.5 for x into 4x - 3

4x - 3

4(9.5) - 3

38 - 3

Suppose we are interested in analyzing the weights of NFL players. We know that on average, NFL players weigh 247 pounds with a

Diano4ka-milaya [45]

Answer:

a) The standard error would be of 8.58 pounds.

b) The margin of error is 14.11 pounds.

c) The 90% confidence interval for the population mean is between 232.89 pounds and 261.11 pounds

Step-by-step explanation:

a.What is the standard error?

The standard error is

$s = \frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample. So

$s = \frac{47}{\sqrt{30}} = 8.58$

The standard error would be of 8.58 pounds.

b.What is the margin of error at 90% confidence?

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.9}{2} = 0.05$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.05 = 0.95$ , so $z = 1.645$

Now, find the margin of error M as such

$M = z*s = 1.645*8.58 = 14.11$

The margin of error is 14.11 pounds.

c. Using my sample of 30, what would be the 90% confidence interval for the population mean?

Lower bound: Sample mean subtracted by the margin of error.

247 - 14.11 = 232.89 pounds

Upper bound

247 + 14.11 = 261.11 pounds

The 90% confidence interval for the population mean is between 232.89 pounds and 261.11 pounds

Can someone pls help me with this?

lara [203]

Answer:

14 is A

15 is B

Step-by-step explanation:

14 . the answer is a because first off the slope is negative so we can immediately eliminate B and D second of all the slope is 1/2 so we can eliminate D and get that the answer has to be a

15. answer is B for this one because first of all the slope is negative so we can immediately eliminate A and c and second of all the y-intercept would be 120 because 90 is what x=1 so we would have to add 30 to get what y would equal when x=0 if that makes sense
