n = 4

Since you divide 6 by 3 to get 2, you divide 12 by 3 and you get 4.

Answer: 4

Step-by-step explanation: This problem is already set out as a proportion. you can cross multiply 6 times n which gives you 6n. Then 12 times 2 which gives 24.

Now you have 6n = 24. You can divide right away, or think of a number when you multiply into 6 gives you 24. Its obvious the answer is 4 because 6 x 4 = 24.

Check:

6/12 = 1/2

2/4 = 1/2

Hope this explanation helps.

aksik [14]

Answer:

x = 15

Step-by-step explanation:

x + 5 = x/2 + 20       Move the 5 over by subtracting

x = x/2 + 15              multiply by 2 on both sides

2x = x + 15               Move the x over by subtracting

1x = 15

I hope this helped and please mark me as brainliest!

A government sample survey plans to measure the LDL (bad) cholesterol level of an SRS of men aged 20 to 34.
svet-max [94.6K]

Answer:

The sampling distribution of x is N(118, 2.5).

Step-by-step explanation:

We have that:

The mean of the population is \mu = 118

The standard deviation of the population is \sigma = 25.

(a) Choose an SRS of 100 men from this population. What is the sampling distribution of x? (Use the units of mg/dL.)

The mean of the sampling distribution is the same as the mean of the population.

The standard deviation of the sampling distribution is the standard deviation of the population divided by the square root of the sample size. So

s = \frac{25}{\sqrt{100}} = 2.5

This means that the sampling distribution of x is N(118, 2.5).
