Answer:
15 because 3 x 5 equals 15
Step-by-step explanation:
Since it's a sample size, we use x, as the mean and s= standard deviation
_
Given: x =27, s = 2 and total sample = 32.
Probability that a recruit is at least 31 years old?
Let's calculate the Z score :
_
X - x 31 - 27
Z = ----------- → Z = -------- → Z = 2 (now look up in the Z score table,
s 2
Area (Z=2) =0.9772 , but Z ≥ 2 (at least) , then :
Area (Z≥2) = Area (Z≤ - 2) = 0.0228
P(≥31)= 0.0228
Answer:
The average number of Tv's sold was higher at store A than at store B
Step-by-step explanation:
You don't have to solve anything. They already gave you the mean/average. They just want to know who sold the most, so in this case you would just see who has the higher number, and see what answer matches.
Answer:
They sold the least lemonade with the recipe that used 7 lemons.
Step-by-step explanation:
A function shows the relationship between a dependent variable and an independent variable. A dependent variable changes as other variables change while an independent variable.
From the function given, the dependent variable is the cups sold which i dependent on the lemons used (independent variable).
From the points, when the lemons used was 3 the cups sold was 37, when the lemons used was 4 the cups sold was 32, when the lemons used was 5 the cups sold was 40, when the lemons used was 6 the cups sold was 35 and when the lemons used was 7 the cups sold was 26.
Hence, They sold the least lemonade with the recipe that used 7 lemons. and They sold the most lemonade with the recipe that used 5 lemons.
