Answer: the minimum number of males over age 25 they must include in their sample n = 306
Step-by-step explanation:
Given;
Mean of milk consumption = 2.5litres
Maximum error E = 0.07
Variance S = 1.21 litres
Confidence interval of 85%
Z' = t(0.075)= 1.44
the minimum number of males over age 25 they must include in their sample = n
n = (Z'×S/E)^2
n = ( 1.44 × 0.85/0.07)^2
n = (17.4857)^2
n = 305.75
n = 306
Answer:
xlog(64)−xlog(2)−2
Step-by-step explanation:
Simplify 6log(2) by moving 6 inside the logarithm.
log(2^6)x − log(2)x − 2
Raise 2 to the power of 6.
log(64)x − log(2)x − 2
Reorder factors in log(64)x − log(2)x −2.
Let l represent length, and w represent width
l=3w-5
P=2(l+w)
46=2(l+w)
Divided 2 for both side
l+w=23
Now, I substitute l=3w-5 into this equation
3w-5+w=23
4w-5=23
Add 5 for both side
4w=28
Divided 4 for both side
w=7 inches
l=3w-5
l=3(7)-5
l=21-5
l=16 inches. As a result, the length is 16 inches, and the width is 7 inches. Hope it help!
