Kate will walk 95 more than 1000 miles in a year the math would be 365x3=1095
X-1= 5x+3x-8
Combine like terms
x-1= 8x-8
Our goal is to isolate x by cancelling out other numbers.
Subtract x from both sides
x-1-x= 8x-x-8
-1= 7x-8
Add 8 to both sides
7=7x
Divide both sides by 7
1=x
Final answer: x=1
Answer:
Step-by-step explanation:
Part 1
P(z < -1.45)
Using the z score table
P =
Part 2
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
a) P(X >52)
x = 52
Mean = 60
Standard deviation = 8
z = 52 - 60/8
z = -1
P-value from Z-Table:
P(x<52) = 0.15866
P(x>52) = 1 - P(x<52) = 0.84134
b) P(48 < x < 64)
Answer: 1350 ft^2
Step-by-step explanation:
The total square footage of the home will be equal to the sum of the areas of each floor.
We know that the ground floor is 25 ft by 30ft, which can be thought of as a rectangle with a length of 25ft and a width of 30 ft.
We know that te area of a rectangle of width W and length L is:
A = L*W
then the area of the ground floor is:
A = 25ft*30ft = 750 ft^2
And the second floor is 20ft by 30ft, then using the same approach as above, the area of the second floor will be:
A = 20ft*30ft = 600ft^2
Then the total square footage of the home is:
SF = 750ft^2 + 600ft^2 = 1350 ft^2
