Answer:

the answer is 35 mi

Step-by-step explanation:

28 squared = 784

21 squared = 441

784+441 = 1225

Square root of 1225 is 35

Carson = C

Hanford = H

Ridgewood = R

CR²=CH²+HR² <=>

<=> CR²=28²+21²=1225 <=> CR=√1225=35

9. black cherry, magnolia, live oak, sweet cherry.

10.because the graph is lowered And that the boxes are needed to go higher ot get to the other numbers and the graph is misleading

Step-by-step explanation:

I don't really understand 8 and 10 so this all i got

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.

PS. I really did try to explain it myself, only to give myself a headache, so please don't be mad and report me. I only wanted to help.

to find the slope you use rise over run to get 2. to check to see the correct equation replace x with any of the x values in the chart and if you get the same y values as the chart then your equation is correct.

Answer:

[tex]total \: balloons = (50 \times 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons[/tex]

Answer:

310

Step-by-step explanation:

The equation that we would use to solve this problem is 7 × 50 - 40 = b

(b is the number of non-yellow balloons)

Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.

7 × 50 = 350.

Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.

350 - 40 = 310

I'd say 13, hope this helps

Answer:

60:90

Step-by-step explanation:

The ratio of girls (G) to boys (B) is 2 : 3.

Given the following data:

In this exercise, you're required to find the ratio of girls (G) to boys (B). In order to do this, we would divide the two values to the least.

[tex]G : B = 60 : 90[/tex]

Dividing both sides by 30, we have;

[tex]G : B = \frac{60}{30} : \frac{90}{30} \\\\G : B = 2 : 3[/tex]

Therefore, the ratio of girls (G) to boys (B) is 2 : 3.

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.

Step-by-step explanation:

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.

Answer:

157 books in each row

Step-by-step explanation:

24 rows=3768 books

1 row=3768/24 books

=157 books

Therefore,Each row contains 157 books

quizlet

Answer:

5 men should be subtracted.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.

How many men should be working to complete the work in 32 days?

20 men - 24 days

x men - 32 days

Then

[tex]32x = 20*24[/tex]

[tex]x = \frac{20*24}{32}[/tex]

[tex]x = 15[/tex]

How many men should be subtracted?

There are 20 to complete in 24 days.

15 are needed to complete in 32 days.

20 - 15 = 5

5 men should be subtracted.
