At a sale, suits were sold for $116 each. This price was 58% of a suit's original price. How much did a suit originally cost?
Fudgin [204]
To find the original price first put the % into decimal form.

58% is 0.58.

Then divide the discounted price ($116) by the % in decimal form:

116 / 0.58

Original price is $200.00

Butoxors [25]

Answer: H_0:\mu=0.44\ ,H_a:\mu

Step-by-step explanation:

Since we have given that

A very large study showed that aspirin reduced the rate of heart attacks by 44%.

we claim that they have a drug that will be more effective than aspirin.

so, our hypothesis would be

H_0:\mu=0.44\\\\H_a:\mu

So, it will be one tail test.

Hence, H_0:\mu=0.44\\\\H_a:\mu

Please I have a 8th grade math question
Soloha48 [4]
<h3>Answer:  2</h3>

==========================================================

Explanation:

x = number of years

y = height in feet

The equation for the first tree is

y = x+3

The slope is 1 to represent a rate of 1 ft per year of growth. The y intercept of 3 is the starting height. Refer to y = mx+b form.

For the second tree, the equation is:

y = 0.5x+4

This time we have a slope of 0.5 and a y intercept of 4.

Apply substitution to solve for x

y = x+3

0.5x+4 = x+3

0.5x-x = 3-4

-0.5x = -1

x = -1/(-0.5)

x = 2

The trees will be the same height in <u>  2  </u> years.

What will that height be? Plug x = 2 into either equation to find y. We should get the same y value.

y = x+3

y = 2+3

y = 5

Or we could say

y = 0.5x+4

y = 0.5*2+4

y = 1+4

y = 5

We've shown that both equations lead to y = 5 when x = 2. This means that at the 2 year mark, both trees are 5 feet tall. This helps confirm we have the correct x value.
