Since y is less than x by 7 times
so in terms of x we write
x=7y
Answer:
4^-2
Step-by-step explanation:
The rules of exponents tell you ...
(a^b)(a^c) = a^(b+c)
This means ...
(4^6)(4^-8) = 4^(6-8) = 4^-2
You must “reverse” the inequality sign to make the statement true: When you multiply by a negative number, “reverse” the inequality sign. Whenever you multiply or divide both sides of an inequality by a negative number, the inequality sign must be reversed in order to keep a true statement.
The difference in the proportion of males and the proportion of females that smoke is 0.08
<h3>Missing information </h3>
In a sample of 61 males, 15 smoke, while in a sample of 48 females, 8 smoke.
<h3>How to determine the proportion difference?</h3>
The given parameters are:
Male Female
Sample 61 48
Smokers 15 8
The proportion is calculated using:
p = Smoker/Sample
So, we have:
Male = 15/61 = 0.25
Female = 8/48 = 0.17
The difference is then calculated as:
Difference = 0.25 - 0.17
Evaluate
Difference = 0.08
Hence, the difference in the proportion of males and the proportion of females that smoke is 0.08

Answer:
Final cost = $3070.90
Step-by-step explanation:
First we need to find the discount
Discount = original price * percent off
Discount = 2200 * .15
Discount = 330
Sale price = original price - discount
Sale price = 3200-330
Sale price = 2870
Now we need to calculate tax
Tax = sales price times tax rate
Tax = 2870 * .07
= 200.90
Final price = sales price plus tax
Final price = 2870 + 200.90
3070.90
