Answer:
the answer is 88
Step-by-step explanation:
Answer: 18b + 2
Step-by-step explanation:
Length: 2b + 4
Width: 7b + 2
I assumed the garden is a rectangle shape since the length and width are different.
Perimeter = 2( L + w)
Then we just plug the values in.
2 (2b + 4 + 7b + 2)
2 (9b + 6) = 18b + 12
So, the equation for the perimeter of Jimmy's garden will be 18b + 2.
Assuming that the room is rectangle and carpet is rectangle
area=legnth times width
legnth=longer than width
12 is longer than 8
12ft=legnth
8ft=width
now convert to yards
1 yard=3 feet
1 foot=1/3 yard
12 ft times 1/3=4yards
8 ft times 1/3=8/3yards
multiply
area=4 tiimes 8/3
area=32/3
area=10 and 2/3 square yards
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)
