Answer:
A) N + Q = 9
B) .05 N + .25 Q = 1.45
Multiplying A) by -.25 we get
A) -.25 N -.25Q = -2.25 then adding B)
B) .05 N + .25 Q = 1.45
-.2N = -.80

5 Quarters
Answer is C
Step-by-step explanation:
A) y=2x
b) y=1.5x
c) Blueberries as it cost less from the strawberries because the slope of the slope of the line is less then the strawberries
(slope is what multiplies with the x value (the horizontal line) and the y (vertical line) is what the answer is, ex: y=2x then for the input (x value) 1 then the output (y value) is 2)

Complete Question:
a) Is it plausible that X is normally distributed?
b) For a random sample of 50 such pairs, what is the (approximate) probability that the sample mean courtship time is between 100 min and 125 min?
Answer:
a) It is plausible that X is normally distributed
b) probability that the sample mean courtship time is between 100 min and 125 min is 0.5269
Step-by-step explanation:
a)X denotes the courtship time for the scorpion flies which indicates that is a real - valued random variable, and since normal distribution is a continuous probability distribution for a real valued random variable, it is plausible that X is normally distributed.
b) Probability that the sample mean courtship time is between 100 min and 125 min
From the probability distribution table:
