Answer:
4/10, 6/15, and 8/20
Step-by-step explanation:
Multiply the numerator and denominator by any of the same number to find equivalent fractions:
2 × 2 / 5 × 2 = 4/10
2 × 3 / 5 × 3 = 6/15
2 × 4 / 5 × 4 = 8/20
You can choose any number you would like to multiply with.

First to get the question correct get's brainliest.
I calculated this myself, and I got the answer 3/4, but I'm trash at explaining long problems. So here is what I found to help explain it. It's not a link.
"If (p, r) lies on the line y = x + b, then
r = p + b…. (1)
If (2p, 5r) lies on the line y = 2x + b, then
5r = 2(2p) + b
or 5r = 4p + b…. (2)
Subtracting equation (1) from (2), we get
5r - r = 4p + b - p - b
4r = 3p or r/p = 3/4"
Since I don't believe in plagiarism here's the person who is a life saver at explaining things.

easy math have fun!!!
Answer:
A = 12
Step-by-step explanation:
First you need to get the length from the perimeter, the formula is l= p/2 - w
After using the formula, you would get 6 for length. The formula for the area of a rectangle is a = lw, so you would multiply 6 and 2 which would give you 12 as your answer.
I apologize if I made any grammar mistakes or if it is unclear.
Answer:
I got area is 12 too
Step-by-step explanation:
2x2=4 because 2 widths
16-4 to find the 2 lengths added up
12÷2 to find the length
6x2=12 because length times width

The quality-control manager at a compact flourescent light bulb factory wants to test the claim that the mean life of a large shipment of cfls is equal to 6500 hours. the population standard deviation is 500 hours. a random sample of 50 cfls indicates a sample mean life of 6,700 hours and sample standard deviation is 600 hours.
Critical values, where P(Z > Z) - a and P(t >) - a 2016-1282 20.06-1645 20.02 -1.960 10.10. - 1.299 10.06.45 - 1677 foto - 2010 1.115 pt.
a. At the 0.05 level of significance, is there evidence that the mean life is different from 6,500 hours?
b. Compute the p value and interpret its meaning.
c. Construct a 95% confidence interval estimate of the population mean life of the CFLs.
d. Compare the results of (a) and (c). What conclusions do you reach?
Answer:
a. At the 0.05 level of significance, there is evidence that the mean life is different from 6,500 hours.
b. The p value= ≈ 0.00480 for z- test which is less than 0.05 and H0 is rejected .
The p value= 0.006913 for t- test which is less than 0.05 and H0 is rejected for 49 degrees of freedom.
c. CI [6583.336 ,6816.336]
d. The range of CI [6583.336 ,6816.336] tells that the cfls having a different mean life lie in this range.
Step-by-step explanation:
Population mean = u= 6500 hours.
Population standard deviation = σ=500 hours.
Sample size =n= 50
Sample mean =x`= 6,700 hours
Sample standard deviation=s= 600 hours.
Critical values, where P(Z > Z) =∝ and P(t >) =∝
Z(0.10)=1.282
Z(0.05)=1.645
Z(0.025)=1.960
t(0.01)(49)= 1.299
t(0.05)= 1.677
t(0.025,49)=2.010
Let the null and alternate hypotheses be
H0: u = 6500 against the claim Ha: u ≠ 6500
Applying Z test
Z= x`- u/ s/√n
z= 6700-6500/500/√50
Z= 200/70.7113
z= 2.82=2.82
Applying t test
t= x`- u /s/√n
t= 6700-6500/600/√50
t= 2.82
a. At the 0.05 level of significance, there is evidence that the mean life is different from 6,500 hours.
Yes we reject H0 for z- test as it falls in the critical region,at the 0.05 level of significance, z=2.82 > z∝=1.645
For t test we reject H0 as it falls in the critical region,at the 0.05 level of significance, t=2.82 > t∝=1.677 with n-1 = 50-1 = 49 degrees of freedom.
b. The p value= ≈ 0.00480 for z- test which is less than 0.05 and H0 is rejected .
The p value= 0.006913 for t- test which is less than 0.05 and H0 is rejected for 49 degrees of freedom.
c. The 95 % confidence interval of the population mean life is estimated by
x` ± z∝/2 (σ/√n )
6700± 1.645 (500/√50)
6700±116.336
6583.336 ,6816.336
d. The range of CI [6583.336 ,6816.336] tells that the cfls having a different mean life lie in this range.

True or false: The equation below is too complicated to use the "isolate the
radical, then square both sides" method to simplify.
Answer: False
=============================================================
Explanation:
The radical is one step away from being fully isolated. We would apply the rule that [tex]\frac{\sqrt{A}}{\sqrt{B}} = \sqrt{\frac{A}{B}}[/tex]
In this case,
[tex]\frac{\sqrt{x+3}}{\sqrt{x-1}} = \sqrt{\frac{x+3}{x-1}}[/tex]
Meaning that the equation
[tex]\frac{\sqrt{x+3}}{\sqrt{x-1}} =3[/tex]
is the same as
[tex]\sqrt{\frac{x+3}{x-1}} = 3[/tex]
From here, we square both sides and use algebra to isolate x.

help find the gradient
Answer:
gradient m = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
y = 3x - 5 ← is in slope- intercept form
with gradient m = 3
Answer:
[tex]\implies\boxed{\rm \red{ Slope (m)= 3 }}[/tex]
Step-by-step explanation:
Given :-
A equation of a line .[tex]\rm y = 3x - 5 [/tex]And we need to find out the gradient of the line . Gradient of line is nothing but the slope of the line . The given equation is in slope intercept form , so we can find out the slope by comparing .
Slope Intercept form :-
[tex]\rm\implies y = mx + c [/tex]
Here m is the slope of the line.Given equation :-
[tex]\rm\implies y = 3x - 5 [/tex]
On comparing :-
[tex]\implies\boxed{\rm \red{ Slope (m)= 3 }}[/tex]
Hence the slope of the line is 3 .
pythagorean theorem!! round to the nearest tenth ..
Answer:
24
Step-by-step explanation:
We are given a leg and the hypotenuse, and we can put what we have into the pythagorean theorem formula:
a^2 + b^2 = c^2
7^2 + b^2 = 25^2
49 + b^2 = 625
b^2 = 576
b = 24

Answer:
$2850
Step-by-step explanation:
The basic idea is that each line of the table is use for that portion of the income that falls in the range for that line of the table. Then the tax amounts are added together.
Another way to do it is to rewrite the table to use the full tax rate on the full income, then subtract a "discount" applicable to that line. Using that method in the attached spreadsheet, we have computed the tax to be $2850 on income of $60,000.

Jenny had 7 dimes and 3 pennies in her She takes a coin out from her pocket, looks at the coin and then replaces it her pocket before she removes a second coin. What is
the probability she will not take out a penny both times?
F. 3/10
G. 9/100
H. 49/100
J. 21/100
=========================================================
Explanation:
There are 7 dimes and 3 pennies, leading to 7+3 = 10 coins total.
The probability of not picking a penny is 7/10. If the first coin is put back, then the probability doesn't change for the second selection.
The probability of getting two dimes is (7/10)*(7/10) = 49/100 when the first coin is replaced.
If the first coin is not replaced, then the answer would be (7/10)*(6/9) = 42/90 = 7/15

What is the area of the triangle?
Answer:
21
Step-by-step explanation:
Add 5.3 + 1.7 and you get 7 (7 is the base of the triangle). Multiply 7 by the height (6) and you get 42. When you put 2 triangles together, it will create a quadrilateral. "Cut the quadrilateral in half" and you will get your triangle's area. The area is 21 :)
Answer:
53.9 square units was my answer, but I learned that it was 21 !
What is the surface area of the rectangular pyramid below? B = 4.8 m
Answer:
625 unit²
Step-by-step explanation:
Surface area of a rectangular pyramid :
Area of base * 4(area of triangular side)
Area of base = length * width
Area of base = 15 * 15 = 225
Height of triangular side = 15
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 *15 * 15 = 112.5 unit²
Surface area = 225 + 4(112.5)
Surface Area = 225 + 450
Surface Area = 625 unit²
