<span>F = {(0, 1), (2, 4), (4, 6), (6, 8)}
G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)}
F(6) = 8
G(6) = 9

Answer:
Confidence interval = 48±4
Step-by-step explanation:
Given:
Mean X = 48
Standard deviation sd = 14.1
Computation:
Z table value of 90% = 1.645
Total number n = 33
Computation:
Margin of error M.E = Z[sd/√n]
Margin of error M.E = 4 approx.
Confidence interval = 48±4
A is the answer. You don't use two because it's a number. And only use too if your exaggerating in the sentence...
-2y = 48 + 6x
-6x - 2y = 48 ——(1)
-6x + 9y = -84
-6x = -84 -9y ——(2)
Substitute (2) into (1):
(-84 -9y) -2y = 48
-84 -9y -2y = 48
-84 -11y = 48
-11y = 48 + 84
-11y = 132
y = - 12
Substitute y = -12 into (1):
-6x -2(-12) = 48
-6x + 24 = 48
-6x = 48 -24
-6x = 24
X = -4
ANS : y= -12, x= -4
Using it's concept, there is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
From the histogram, the number of pitches is given by:
1 + 5 + 3 + 4 + 1 + 2 = 16.
Of those, 2 were between 70 and 75 mph, hence the probability is given by:
p = 2/16 = 1/8 = 0.125.
There is a 0.125 = 12.5% probability that Craig will pitch it between 70 and 75 mph.
