Answer:
a. 6Pack of paint brushes for $12.99
b. 5 classes for $64.99
c. 12 pack of paper plates
Step-by-step explanation:
a.
I could buy a 6 pack of paint brushes for $ 12.99
or
buy 6 individual brushes for the price of $ 2.19 each.
6 x $2.19 = $13.14
first option is cheaper
b.
10 classes for s total of $150
$150 ÷ 10 = $15 (price per class)
5 classes for $64.99
$64.99 ÷ 5 = $12.998 (price per class)
c.
12 pack of paper plates for $2.29
25 pack for $4.99
$2.29 ÷ 12 = $0.1908 (price of one plate)
$4.99 ÷ 25 = $0.1996 (price for one plate)
Answer:
15.866%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 3,282 gallons of kerosene
μ is the population mean = 3,087 gallons of kerosene
σ is the population standard deviation = 195 gallons
For x > 3282 gallons
z = 3282 - 3087/195
z = 1
Probability value from Z-Table:
P(x<3282) = 0.84134
P(x>3282) = 1 - P(x<3282) = 0.15866
Converting to percentage
0.15866 × 100 = 15.866%
The percent of flights on these particular routes that will burn more than 3,282 gallons of kerosene is 15.866%
Factor out the largest perfect square of 32.
( in this example we factored out 16 )
Rewrite
____
/16⋅2
as the product of two radicals.
The square root of 16 is 4.
Divide numerator and denominator by 4.
