Answer:
Step-by-step explanation:
find the attachment showing std normal curve symmetrical about y axis.
Equal probabilities on either side of the mean thus the total probability to the right of mean is 0.50
From the table we can find that
a) P(Z>2.5) = 0.5- area lying between 0 and 2.5
= 0.5-0.4938 =0.0062
b) P(1.2<z<2.2) = F(2.2)-F(1.2)
= 0.9861-0.3849
=0.6012
Answer:
<em>3 3/4 feet</em>
Step-by-step explanation:
Given
Perimeter of the garden = 20ft
If he wants the length of the garden to be 2 1/2 longer than its width, then;
L = 2 1/2 + W
L is the length
W is the width
Perimeter of the garden = 2(L+W)
P20 = 2(5/2 + W+W)
20 = 5 + 2W+2W
20 - 5 = 4W
15 = 4W
W = 15/4
<em>W = 3 3/4 ft</em>
<em>Hence the width of the garden is 3 3/4 feet</em>
