Answer:

A rectangle is one. If that is one of the options, this would be the correct answer.

Step-by-step explanation:

A quadrilateral can be proved to be a rectangle in several ways. Here are three simple methods: 1) Demonstrate that all angles are 90°; 2) Demonstrate that one set of sides is parallel and that two opposite angles are 90°; and 3) Demonstrate that the diagonals are bisected and equal in length.

Ghella [55]

Answer:

boys percentage 68%

girls percentage 32%

difference 68 - 32 = 36% = 180

36 ÷ 18 = 2 × 50 = 100

180 ÷ 18 = 10 × 50 = 500

1. Suppose people ages 16-30 make up 15% of drivers on the road, 80% of drivers are aged 31-64, and 5% of drivers are aged 65+.
Yuliya22 [10]

Answer:

0.8675

Step-by-step explanation:

Given that people ages 16-30 make up 15% of drivers on the road, 80% of drivers are aged 31-64, and 5% of drivers are aged 65+.

Furthermore, suppose drivers in each age range cause car accidents at the rates of 6%, 4%, and 9%, respectively.

age 16-30 31-64 >65  

Prob 0.15 0.8 0.05 1

Prob for accidents 0.06 0.09 0.04  

Product 0.009 0.072 0.002 0.083

Prob for 31-64 causing it/accident =\frac{0.072}{0.083} \\=0.8675

Using Bayes theorem we got answer as 0.8675

Solve for x with 45 degree angle & 60ft side
Alona [7]

Answer:

x = 84.85281374 ft

Step-by-step explanation:

We know that sin theta = opposite/ hypotenuse

sin 45 = 60/x

Multiply each side by x

x * sin45 = 60/x*x

x sin 45 = 60

Divide each side by sin 45

x = 60/sin 45

x = 84.85281374 ft
