Answer:
y represents the total amount he spent in x amount of rides+ the $10 fee.
Step-by-step explanation:
At x=0, y=10 because he needs to pay $10 to enter, and he haven't rode on anything yet.
x=1, y=12
x=2, y=14
x=3, y=16
... and so on.
That would be 1/2 divided by 3
Its A
" = inches
' = feet
the scale is 1:30
3" * 30" = 90"
4" * 30" = 120"
the room is 90" by 120"
90" / 12" = 7.5'
120" / 12" = 10'
the room is 7.5' by 10'
7.5' * 10' = 75' ^2
^ = exponential sign (10^2) means 10 to the second power.
The area of the room is 75' ^2
Answer:
The average weekly grocery bill per four-person family in the town is significantly different from the national average.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = $100
Sample mean,
= $103.23
Sample size, n = 25
Alpha, α = 0.05
Sample standard deviation, s = $8.82
First, we design the null and the alternate hypothesis
We use Two-tailed t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,

We accept the null hypothesis.
We accept the null hypothesis and determine that the average weekly grocery bill per four-person family in the town is significantly same to the national average.
