Answer:
x = 12.
Step-by-step explanation:
2x + 6 + 4x + 2 = 2(5x - 20) (The sum of the outer parallel sides = 2 * middle parallel line).
6x + 8 = 10x - 40
48 = 4x
x = 12.
For the answer to this questions,<span>a. P (z ≤ z0) = 0.0401=P(z ≥ z0) = 1-0.0401 = 0.9599 = P(z ≤ -z0) = 0.9599
From tables z0 = -1.75
b. P (-z0 ≤ z ≤ z0) = .95 = P (z ≤ z0)- P (z ≤ -z0) = P (z ≤ z0)- P (z ≥ z0) =
P (z ≤ z0)-(1- P (z ≤ z0))
P (z ≤ z0) = (0.95+1)/2=0.975
From tables z0 = 1.96
c. P (-z0 ≤ z ≤ z0) = 0.90
the procedure is the same that exercise b P (z ≤ z0) = (0.9+1)/2=0.95
From tables the nearest value is z0 = 1.64
</span>d. P (-z0 ≤ z ≤ 0) = 0.2967= P (z ≤ 0) - P (z ≤ -z0) = P (z ≤ 0) - P (z ≥ z0) =
<span>P (z ≤ 0) - (1- P (z ≤ z0)) </span>
<span>P (z ≤ z0) = 0.2967 + 1 - P (z ≤ 0)= 0.2967 + 1 - 0.5 = 0.7967 </span>
<span>From tables z0 = 0.83

6 and 8/15 inches. Take the 1/5 and 1/3 and find a common denominator. Then Subtract the smaller number from the bigger number. Bam
Answer:
1260 ft^2
Step-by-step explanation:
Since it has to be whole numbers, the first divide 142 by 2. It gives you 71. The maximum area is when the sides L1 and L2 are almost the same. The best is 35 and 36. 35*36 is 1260ft^2.
