Step-by-step explanation:
(find the percent by multiplying the percentage, .45, by the total number of shoes = 18 shoes)
% = 45%
p = 18
w = 40
(i did 100/40 which equals to 2.5 then multiplied 2.5 by the numerator so the numerator and denominator would both be equivelant.)
18/40 = 45/100
(multiply the whole (40) by the decimal value (.45) which is equal to 18)
40 x .45 = 18
(answer)
If Ms. M has 40 pairs of shoes, 18 of those shoes are sneakers.

Researchers studying the sticky droplets found on spider webs will measure the widths of a random sample of droplets. From the sample, the researchers will construct a 95 percent confidence interval to estimate the mean width of all such droplets. Write the correct statement about a 95 percent confidence interval for the mean width.
Answers
Answer:
The interval will be narrower if the researchers increase the sample size of droplets.
Step-by-step explanation:
The confidence interval can be obtained using the relation :
Xbar ± Margin of error
Margin of Error = Zcrit * s/sqrt(n)
Zcritical = critical vlaue at the specified α - level
n = sample size ; s = standard deviation
Sample size being the denominator, will reduce the overall value of the error margin as we utilize a larger sample.
Hence, the interval becomes narrower as the error margin is reduced which is achieved by employing an increased sample size.
Answer:
B. The interval will be narrower if the researchers increase the sample size of droplets.
Step-by-step explanation:
B. The interval will be narrower if the researchers increase the sample size of droplets.
Margin of error of a confidence interval:
The higher the margin of error, the wider an interval is.
In which z is related to the confidence level(the higher the confidence level, the higher z), is the standard deviation of the population and n is the size of the sample.
From this, we conclude that:
If we increase the confidence level, the interval will be wider.
If we increase the sample size, the interval will be narrower.
Which of the following statements about a 95 percent confidence interval for the mean width is correct?
Increasing the sample size leads to a narrower interval, so the correct answer is given by option B.

Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%

Mount McKinley, in Alaska, is about 3.848 miles high. If a mountain climber can climb 0.25 miles per day, about how long to the nearest day, would it take to climb Mount McKinley?
Answers
Answer:
About 16 days.
Step-by-step explanation:
The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.

y = 3x + 3
y = x − 1
Answers
Given both y values, you know that they have to be equal
3x + 3 = x - 1
2x + 3 = -1
2x = -4, divide by 2
x = -2
Now plug x value into any of the equation to find y value
y = 3(-2) + 3
y = -6 + 3, y = -3
Solution: x = -2, y = -3
Answer:
Step-by-step explanation:
Well you have to solve for X to find Y simplified.
Since both equations equal Y you can plug them together
3x+3=x-1
-x -x
2x+3=-1
-3 -3
2x=-4
Divide -4 by 2 and you get X = -2 then plug X into both equations and boom

If the interest of a sum of money in 6years is 3 by 8 of the principal what is the rate of interest
Answers
Answer: rate of interest (r) = 6.25
Step-by-step explanation:
Simple interest formula is S.I = PxTxR/100
From the question ;
S.I = (3/8) principal
3/8p = px6xr/100
Eliminate p on both sides of the equation
r = (3x100) / (8 x 6)
r = 300 / 48
r = 6.25
Use the distributive property with factoring to find the equivalent expression. 24n + 32w = (3n + w)
Answers
Answer:
Step-by-step explanation:
24n + 32w = (3n + w)
We're asked to use distributive property, this means that we have to find a way that the given expression on the left hand side is equal to the given incomplete exresssion on the right hand side. In so doing, we're fulfilling the distributive property tag.
Given 3n, 3 factorises 24 into 8, and at the same time, factorises 32 into 4. Thus, we can then conclude that
24n + 32w = 8(3n + 4w)

What is the volume of the figure?
Answers
Answer:
volume of a cone = [tex]\pi[/tex] [tex]r^{2}[/tex] h/3
[tex]\pi[/tex] = 22/7 or 3.14
r (radius) = 8 ft
h (height) = 16 ft
∴ volume = 22/7 * 8 * 8 * 16/3
= 3.14 * 64 * 16/3
= 1072.76190476 [tex]ft^{3}[/tex]
hope this answer helps you.....
please mark as brainliest ..... thank you....
Answer:
1072 ft³
Step-by-step explanation:
Formula we use,
→ V = πr²(h/3)
Now the volume of cone is,
→ πr²(h/3)
→ 3.14 × (8)² × (16/3)
→ 3.14 × 64 × 5.333
→ 200.96 × 5.333
→ 1072.33
→ ≈ 1072 ft³
Hence, volume is 1072 ft³.
2/3 - 3/2y + 1/3y + 4 = 0
Answers
Answer:
y = 4
Step-by-step explanation:
(2/3 + 4) + (-3/2y + 1/3y) = 0
(-3/2y + 1/3y) = -4 2/3
-9/6y + 2/6y = -14/3
-7/6y = -14/3
cross-multiply:
-21y = -84
y = 4
Answer:
y = 4
Step-by-step explanation:
Please use parentheses for clarity, remembering what big differences they make in expression values.
I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0" actually means
2/3 - (3/2)y + (1/3)y + 4 = 0
The LCD here is 6, which is the product of the denominators 2 and 3.
Then your "2/3 - 3/2y + 1/3y + 4 = 0" becomes:
4 - 9y + 2y + 24 = 0, which simplifies to:
28 - 7y = 0. Solving this, we get y = 4
