True [87]

Step-by-step explanation:

consider k the numbe of correct answers

P(k) = kC8×(0,2)^k×(0,8)^(8-k)

example:

The probability of having 2 correct answers = 2C8×(0,2)^2×(0,8)^(6) = 0.294

the probability that the number x or correct answer is fewer than 4 =

p(0) + p(1) + p(2) + p(3) = 0.944

Trapezoid ABCD has an area of 525 cm squared. If height AB = 21 cm and BC = 37 cm, what is the measure of AD?

Annette [7]

Answer:

AD = 13

Step-by-step explanation:

Area of trapezoid ABCD

$= \frac{1}{2} (AB + AD) \times AB \\ \\ 525= \frac{1}{2} (37+ AD) \times21\\ \\ 525 \times 2= (37+ AD) \times21 \\ \\ 1050 = 21 \times 37 + 21AD \\ \\ 1050 = 777+ 21AD \\ \\ 21AD = 1050 - 777 \\ \\ 21AD = 273 \\ \\ AD = \frac{273}{21} \\ \\ AD = 13$
