Okay so what we’re doing here is that you have to divide 15 by 4. It won’t actually be a whole number because it’s going to have a remainder if you don’t know what a remainder is it’s a number that is left over. An example is like 15 divided by 8 is 1 remainder 7 , but long story short the answer is 3 remainder 3 ( 3 R3)

Find the length of the second base of a trapezoid with one base measuring 15 feet, a height of 7.6 feet, and an area of 98.8 squ

scoray [572]

Answer:

11 feet

Explanation:

area of trapezoid: 1/2 * (a + b) * h

Here given:

a = 15 feet

height = 7.6 feet

area = 98.8 feet²

====================

Solving steps:

⇒ 1/2 * (15 + b) * 7.6 = 98.8

⇒ (15 + b) * 7.6 = 197.6

⇒ (15 + b) = 26

⇒ b = 11 ft

0.25

0.40

0.60

0.75

<span>Solution:

The maximum limit from the table is 182
And the minimum value is 177.

Therefore,
Using the probability concept,

P( x < 180 ) = (180 - 177) </span>÷ 182 - 177

P( x < 180 ) = 3 ÷ 5

P( x < 180 ) = 0.60
