What is the other match?
Answer:
A
Step-by-step explanation:
solve: |2x-1| ≥ 4x+3
Step-by-step explanation:
consider the sign as equals then
move 2x right side 3 on left
solve it
answer is 2
Question is: 2x - 1 >= 4x + 3
First, join the like terms together.
-> So 2x moves into 4x, meaning it becomes negative -2x on the other side.
-> The number 3 moves into the other side which also becomes negative.
Now the equation will look like this:
- 3 - 1 >= 4x - 2x
- 4 >= 2x
Put 2 on the other side with - 4, and it will divide (not plus or minus as 2 was combined with an unlike term).
It looks like this now:
- 4/2 >= x
- 2 >= x
This is the answer.
Calculate the value of the sample variance. Round your answer to one decimal place. 9_5,9_5,2,9_5
Answer:
[tex]s^2 = 0.01[/tex]
Step-by-step explanation:
Given
Values: 9/5, 9/5, 2, 9/5
Required
Calculate the sample variance
Sample variance is calculated using:
[tex]s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1}[/tex]
First, we calculate the mean
[tex]\overline x = \frac{\sum x}{n}[/tex]
[tex]\overline x = \frac{9/5 + 9/5 + 2 + 9/5}{4}[/tex]
[tex]\overline x = \frac{7.4}{4}[/tex]
[tex]\overline x = 1.85[/tex]
[tex]s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1}[/tex] becomes
[tex]s^2 = \frac{(9/5 - 1.85)^2+(9/5 - 1.85)^2+(2 - 1.85)^2+(9/5 - 1.85)^2}{4 - 1}[/tex]
[tex]s^2 = \frac{(-0.05)^2+(-0.05)^2+(0.15)^2+(-0.05)^2}{4 - 1}[/tex]
[tex]s^2 = \frac{0.0025+0.0025+0.0225+0.0025}{3}[/tex]
[tex]s^2 = \frac{0.03}{3}[/tex]
[tex]s^2 = 0.01[/tex]
Hence, the variance is 0.01

An isosceles triangle has an angle that measures 56º. Which other angles could be in that
isosceles triangle? Choose all that apply.
HELP PLEASE I NEED THIS
Answer:
The other angles can be 56°, 68°, or 62°.
Step-by-step explanation:
If the 56° angle is one of the two congruent angles, then the remaining angles are 56° and 180-2(56) = 68°
If the is 56° Is not congruent to either of the other angles, then each of the remaining two angles is (180-56)/2 = 62°.
The other angles can be 56°, 68°, or 62°.

Writing Prompt Algebra I
Your aunt is planning on building a rectangular pool that measures 10 feet by 12 feet. A
concrete walk around all four sides of the pool will also be included in the deal. However,
your aunt is not sure how big to make the width of the walk. Therefore, the width will be
“x” feet long. Your aunt is wondering how much land will be needed for the pool and the
walkway bordering the pool. You are to write a written description to your aunt telling her
how you would find the area of land needed for the pool and the walkway bordering all four
sides.
Answer: The width is 12 feet, since the pool measures 10 by 12.
Step-by-step explanation:
Your aunt will need 120 square feet of land. I know this because you multiply the length by the width, it equals 120. Then I have to look for the perimeter, and I do this by adding the length twice and add the width twice. This would equal 42.

Answer:
SAS (side-angle-side)
Step-by-step explanation:
In the given picture, it is shown that the triangles have two congruent sides, and one congruent angle between them. The congruent sides are shown by the lines on the sides. The congruent angle is shown by the box outlining the angle (technically a box outlining the angle demonstrates that the angle is a right angle, either way, it proves the congruency).
Delilah deposits 8,255 in an account that pays 4.2% simple interest. How much money will be in her account after 8 years
Answer:
11235.35
Step-by-step explanation:
Given data
P=8225
R=4.2%=0.042
T=8years
The simple interest formula is
A=P(1+rt)
Substitute
A=8225(1+0.042*8)
A=8225(1+0.336)
A=8225*1.366
A=11235.35
Hence the balance will be 11235.35

Last year, Bob's Market ordered 15 1 2 15 2 1 pounds of plums from a local orchard. This year, the market plans to order 1 1 4 1 4 1 times as many pounds of plums as were ordered last year. They want 2 5 5 2 of this order to be red plums. What is the total amount, in pounds, of red plums the market plans to order this year?
Answer: 7 3/4 pounds
Step-by-step explanation:
Here's the correct question:
Last year, Bob's Market ordered 15 1/2 pounds of plums from a local orchard. This year, the market plans to order 1 1/4 times as many pounds of plums as were ordered last year. They want 2/5 of this order to be red plums. What is the total amount, in pounds, of red plums the market plans to order this year?
The amount of pounds of plum that is ordered this year will be:
= 15 1/2 × 1 1/4
= 31/2 × 5/4
= 19 3/8
Since they want 2/5 to be red plums, the total amount of red plums will then be:
= 2/5 × 19 3/8
= 2/5 × 155/8
= 310/40
= 7 3/4 pounds

Problem 5
A shoe store purchases a pair of shoes for $75
before a mark up is applied.
There is a 140% markup. After the markup, a 6%
sales tax is added.
What is the total after discount and tax?
Answer:
$78.9
Step-by-step explanation:
Given data
We are told that the store purchased the shoe before mark up, hence we only need to solve for the tax
tax= 6%
=6/100*75
=0.06*65
=$3.9
Hence the total is
=75+3.9
=$78.9
