Answer:
first multiply the numbers in side the parentheses, make the number an improper fraction(check for cross multiplication) then multiply.
Step-by-step explanation:
You subtract 6 from both sides, and then multiply by 6 on both sides. You should get -20.
Solution-
89.50/2 = 44.75
44.75 is the amount he spent to buy his nephew the pair of shoes.
Now, we are going to add the amount he spent for himself and his nephew together.
89.50 + 44.75= 134.25
134.25 is the amount he spent in total, now we need to find the final amount with sales tax included.
We can do this by multiplying the total price by .075
134.25 * .075 = 10.07 (I rounded this to the nearest hundredths because we are dealing with money)
Now we need to add the two number together.
134.25 + 10.07 = 144.32
Answer-
The total amount Kyle spent is $144.32
Answer:
(1) 0.4207
(2) 0.7799
Step-by-step explanation:
Given,
Mean value,
Standard deviation,
(1) P(X ≥ 17.5) = 1 - P( X ≤ 17.5)
( By using z-score table )
= 0.4207
(2) P(14 ≤ X ≤ 18) = P(X ≤ 18) - P(X ≤ 14)
= 0.9918 - 0.2119
= 0.7799
