Hello! I can help you with this! So what we need to do is convert fractions to decimals. If you know basic fractions, 1/4 = 0.25, And 1/5 = 0.2. In this case, here are the numbers converted into decimal form.

8 1/4 = 8.25
1 1/5 = 1.2
2 1/4 = 2.25
6 1/5 = 6.2

Now this question is asking for the perimeter around the figure. In this case, we have to add up all of the sides. When we add up all of the numbers, you should get 17.9 or 17 9/10 in simplest fraction form. There. The perimeter is 17 9/10 meters.

There are 4,000 undergraduates registered at a certain college. Of them, 364 are taking one course, 496 are taking two courses,
kykrilka [37]

Answer:

X=1, P = 0.091

X=2, P = 0.124

X=3, P = 0.115

X=4, P = 0.378

X=5, P = 0.264

X=6, P = 0.028

Step-by-step explanation:

To calculate the probability distribution of X, first we have to define the sample space.

In this case X=1,2,3,4,5,6. This are the values that X can take.

The probability is calculated as equal to the relative frequency of each of the values.

For X=1, P = 364/4000 = 0.091

For X=2, P = 496/4000 = 0.124

For X=3, P = 460/4000 = 0.115

For X=4, P = 1512/4000 = 0.378

For X=5, P = 1056/4000 = 0.264

For X=6, P = 112/4000 = 0.028

What is the area of the sector formed by RAP? The radius is 10 inches.
irina1246 [14]

Answer:

≈ 39.3 in²

Step-by-step explanation:

The area of the sector is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{45}{360}

  = π × 10² × \frac{1}{8}

  = \frac{100\pi }{8} ≈ 39.3 in² ( to 1 dec. place )
