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
Answer:
x = 1, -5
Step-by-step explanation:
The answer to the equation is 0 right? So you have to find the value of x to make this equation true. To make (x - 1) equal 0, x has to equal 1, because if x equals 1, then 1 - 1 = 0. It's the same for (x + 5). X would have to equal -5. -5 + 5 = 0.
Pls give brainliest.
Let hot dogs = X
So then soda would be 2x ( two times as much).
Now you have:
X + 2X = 162
Simplify:
3x = 162
Divide both sides by 3:
X =162 / 3
X = 54
2x = 54 *2 = 108
108 sodas and 54 hot dogs were sold.
