Take 5 to the left:
(10×5)x = y
50x = y
Answer:
a. 0.68 or 68%
b. 0.08 or 8%
c. 0.32 or 32%
Step-by-step explanation:
Probability of reaching client on the first call = 60%
Probability of reaching client on the second call = 20%
a. The probability that the manager reaches her client in two or fewer calls is the probability of reaching a client with one or two calls:
b. The probability that the manager reaches her client on the second call but not on the first call is:
c. The probability that manager is unsuccessful on two consecutive calls (needing more than two calls), P(X>2), is:
Answer:
Part 1)
Part 2)
Part 3) and
Step-by-step explanation:
see the attached figure with letters to better understand the problem
step 1
Find the side b
we know that
In the right triangle ABC
The function sine of angle B is equal to divide the opposite side angle B (AC) by the hypotenuse (AB)
we have
substitute
solve for b
step 2
Find the side a
we know that
In the right triangle ABC
The function cosine of angle B is equal to divide the adjacent side angle B (BC) by the hypotenuse (AB)
we have
substitute
solve for a
step 3
Find the measure of angle A
we know that
In the right triangle ABC
----> is a right angle
∠A+∠B=90° ------> by complementary angles
substitute the given value
x-intercept = 80/-32 = 5/-2 = -2.50000
y-intercept = 80/1 = 80.00000
