Suppose the mean value of a population is 51, and many samples are taken from the population. As the size of each sample increases, the mean of the sample means would approach which of the following values? A. 48 B. 54 C. 51 D. 45

Answers

Answer 1

The mean of the sample means would approach the following value:

C. 51.

What is defined by the Central Limit Theorem?

The Central Limit Theorem defines the distribution of the sampling distribution of sample means with size n of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex].

For the sampling distribution, the mean and the standard deviation are given as follows:

Mean: [tex]\mu[/tex], that is, the same as the population mean.Standard deviation: [tex]s = \frac{\sigma}{\sqrt{n}}[/tex], which is the population standard deviation divided by the square root of the sample size.

The mean of the sample means should be approximated to the population mean, hence it is given by 51.

A. The slope m is rise over run, so y over x =m. Solve for Y to get y=mx.

B. The slope m is run over rise, so x over y=m. Solve for x=ym.

C. The slope m is run over rise, so x over y=m. Solve for y to get y= x over m.

D. The slope m is rise over run, so x over y=m. Solve for x to get x=ym.

Ken made $14,500 in five months at his new job. How much can he make in two years if his pay remains constant?

Answers

Answer:

$69,600

Step-by-step explanation:

Figure out how much Ken makes a month by dividing 14500/5.

This gives you $2900.

If Ken makes $2900 a month and there are 24 months in two years, multiply his monthly earnings by 24 months.

$2900 * 24 = $69,600

$69,600



Explanation:


First you would do 14500/5 to find out how much he made in one month.

14500/5=2900
Meaning they made $2900 per month so then to find out how much he would make in two years you would multiply it by 24 because two years is 24 months

2900*24= $69600

1.125 or 9/8 batches of muffins

Step-by-step explanation:

m = 0.5s where m = the amount of muffins and s = the lb of strawberries

m = 0.5(2.25)

m = 1.125 or 9/8 batches of muffins

Answer:

4.5 batches

Step-by-step explanation:

1 batch = 1/2 poundsx  batches = 9/4 pounds

x*1/2 = 1*9/4x = 9/4*2x = 9/2x = 4.5 batches

On a 1 mile track, Runner A has made 18 laps in the time it took Runner B to make 8 laps. If Runner A is running 5 mph faster than Runner B, how fast is each of them running?

Answers

Answer:

Runner A is running at 9 mph while runner B is running at 4 mph

Step-by-step explanation:

From online values, 4 laps make 1 mile.

We are told Runner A has made 18 laps in the time it took Runner B to make 8 laps.

This means that runner A has run in mile; 18/4 = 4.5 miles

While runner B has run in miles; 8/4 = 2 miles

Runner A is running 5 mph faster than Runner B, thus speed of runner A is;

V_b + 5 while speed of runner B is V_b.

We know that; time = distance/speed

Thus;

t_a = 4.5/(V_b + 5)

t_b = 2/V_b

Since the times are equal from the question, then;

4.5/(V_b + 5) = 2/V_b

Cross multiply to get;

4.5V_b = 2(V_b + 5)

4.5V_b = 2V_b + 10

4.5V_b - 2V_b = 10

2.5V_b = 10

V_b = 10/2.5

V_b = 4 mph

Since V_a = V_b + 5

Thus, V_a = 4 + 5 = 9 mph

Runner A is running at 9 mph while runner B is running at 4 mph

(02.07)A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.

A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n.

Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p − m∠o = 90 degrees (alternate interior angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p

In which step did the student first make a mistake and how can it be corrected?

Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)

Answers

Answer:

I'm pretty sure it's the last option. Step 2; it should be m<o+m<p=180 degrees (supplementary angles)

Step-by-step explanation:

I think it's the last one since m<o and m<p are supplementary.
