Please help me with this

Answer:

3/8

Step-by-step explanation:

Find the height of the trapezoids

20 - 10 = 10

10/2 = 5

Find the area of the trapezoids

5*(20+10)/2 = 75

The formula for the area of the trapezoid is the height * the bases added together divided by 2

75*2(this is because there are 2 trapezoids) = 150

Put this to proportion of the total area of the dart board

150/ $20^{2}$ = 150/400 = 3/8

3/8 is the probability that you score 3 points

Suppose 86% of 50 people at a law firm like their job. How many people like their job.

solniwko [45]

To find 86% of 50, you do 50*.86 (because .86 is the decimal form of the percentage 86%)

50*.86=43 people

Hope this helps
