Answer:
x=3
Step-by-step explanation:
1/4x=1/2+1/4
1/4x=3/4
4*1/4x=3/4*4
x=3
Answer:
u = 5.176 oz
Step-by-step explanation:
Given:
standard deviation = 0.4
P(x>6) = 2℅ = 0.02
The complement role:
P(A°) = P(not A)
= 1 - P(A)
P(x<6) = 1, P(x>6) = 1 = 0.02 =
= 1-0.02 = 0.98
Taking the closest probability 0.9893 which is on row 2.0 column .06 in the probability table, we now have a z score of
2.0 + 0.06 = 2.06
Zo = 2.06
Therefore, Z score is expressed as
Zo = (x -u) / sd
We already know Zo = 2.06
x = 6
u = ?
sd = 0.4
Therefore,
2.06 = (6 - u) / 0.4
= 2.06 * 0.4 = 6 - u
u = 5.176
A=8,502×(1−0.13)^(16)
A=915.86
You can make this into an inequality, using x as the number of uniforms.
100 + 12x < 61 + 15x
39 < 3x
13 < x, so they must buy more than 13 to get a better deal.
