Answer:

0.11.

Step-by-step explanation:

From the given table it is clear that,

Probability that the selected seventh grader takes the bus = 0.44

Probability that the selected seventh grader drop off by parents = 0.12

Total probability of seventh Grader = 0.56

Probability that the selected eighth grader takes the bus = 0.11

Probability that the selected eighth grader drop off by parents = 0.33

Total probability of Eighth Grader = 0.44

Therefore, the selected eighth grader takes the bus is 0.11.

Zigmanuir [339]

Answer:

0.12 miles is it flying per second.

Step-by-step explanation:

The distance d is related to time t in seconds is given by the equation as follows :

d =0.12 t

We need to find how many miles is it flying per second.

$\dfrac{d}{t}=0.12\\\\\dfrac{\text{miles}}{\text{second}}=0.12$

So, the speed of the airplane is 0.12 miles per second, Hence, 0.12 miles is it flying per second.

Using suitable identity find 231^222-131^2

Sliva [168]

Given:

Consider the expression is

$231^2-131^2$

To find:

The value of given expression using a suitable identity.

Solution:

We have,

$231^2-131^2$

Using the identity $a^2-b^2=(a-b)(a+b)$ , we get

$231^2-131^2=(231-131)(231+131)$

$231^2-131^2=(100)(362)$

$231^2-131^2=36200$

Therefore, the value of the given expression is $231^2-131^2=36200$ .

Find the perimeter of the triangle.

Klio2033 [76]

9514 1404 393

Answer:

84 in

Step-by-step explanation:

The Pythagorean theorem is used to find the length 'b'.

b^2 +12^2 = 37^2

b = √(37^2 -12^2) = √1225 = 35

Then the perimeter is the sum of side lengths:

P = a + b + c = 12 + 35 + 37

P = 84 . . . inches
