2. A New Jersey-based statistics professor has collected data over several years concerning the duration of her morning commute to her university. A brief inspection of the data reveals that her commuting times are (roughly) normally distributed with a mean of 75 minutes and standard deviation of 15 minutes. If she leaves her home at 9:00 a.m. to attend a faculty meeting commencing at 10:30 a.m., what is the probability she will be late for the meeting?

Answers

Answer 1
It will be 1 hour and 30 minutes

Answers

Answer:

150

Step-by-step explanation:

First a diagram which looks like a 12 sided figure where all the sides are equal.

Now draw 2 consecutive radii.

There are 12 such triangles in a 12 sided polygon.

These triangles have an apex angle of 360 / 12 = 30 degrees.

The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180

2x = 150

x = 75

But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150

a random sample of 21 students from the U and at A&T were surveyed about their music listening habits. Their responses (in hours, each square represents 0.5 hour) were recorded and displayed using the following histograms. The left represents U. The right represents SHSAT. Which data set(U or SHSAT students) has a larger standard deviation? Explain.​

Answers

Answer:  U

Step-by-step explanation:

Looking at the graphs, U is skewed right and SHSAT is more of a normal distribution. Generally, this means the standard deviation would be greater for the data set that is skewed.

Let's find the standard deviation for each data set to confirm our theory.

Step 1) Find the mean number of hours

Step 2) Subtract each data value from the mean

Step 3) Find the mean of Step 2

U

hours x frequency: 1(3) + 2(5) + 3(4) + 4(3) + 5(3) + 6(2) + 9(1) = 72

Step 1: mean = (hours x frequency)/frequency = 72/21 = 3.4

Step 2: 2.4(3) + 1.4(5) + 0.4(4) + 0.6(3) + 1.6(3) + 2.6(2) + 5.6(1) = 33.2

Step 3: standard deviation = (sum from step 2)/ frequency = 33.2/21 = 1.58

SHSAT

hours x frequency: 1(1) + 2(3) + 3(4) + 4(5) + 5(3) + 6(3) + 7(2) = 86

Step 1: mean = (hours x frequency)/frequency = 86/21 = 4.1

Step 2: 3.1(1) + 2.1(3) + 1.1(4) + 0.1(5) +0.95(3) + 1.9(3) + 2.9(2) = 28.5

Step 3: standard deviation = (sum from step 2)/ frequency = 28.5/21 = 1.36

The calculations confirm that U has the greater standard deviation

Mr. Wagner is on a diet. He currently weighs 250 pounds. He loses 3 pounds per month. Write an equation that represents his weight after m months. After how many months will Mr. Wagner reach his goal of 220 pounds.

Answers

Answer:

y=mx+b

Step-by-step explanation:

In this case, x is represented by m. B is how much he weighs at the start which is 250. How many pounds does he lose per month ? 3. Thus, we conclude:

220=3x+250

Answer:

10 months

Step-by-step explanation:

220+3m = 250

Subtract 220 from both sides, now it is 3m=30. So now divide 3 on both sides. So now we have our answer m=10.
