Answer:
Ok, so with this problem, you would start with the equation 6/10=x/38.
Then, cross multiply:
38(6)=10x
After, you would:
38 x 6 = 228
Then:
228/10
Lastly:
x=22.8m which when rounded equals 23 ft.

Write 1.6 x 10 in standard form.
Answer:
[tex]1.6 \times 10 = 16 \\ [/tex]
To multiply a decimal by 10, move the decimal point in the multiplicant by one place to the right. Here we multiplied the number 1.6 by 10 so we move 1 place to the right.
To multiply a decimal by 100, move the decimal point in the multiplicant by two places to the right.
What is the slope-intercept form of the following equation?
2x+2y=20
Question 2 options:
y= x+10
2y= -2x+20
y= -x-10
y= -x+10
Answer:
[tex]y=-x+10[/tex]
Step-by-step explanation:
First we must know the format of slope-intercept form!
This is: [tex]y=mx+b[/tex] (where "m" is the slope and b is the y-intercept)
Given this equation: [tex]2x+2y=20[/tex] we must convert this into the format of slope-intercept form.
First, we should move the "2x" to the other side of the equation, we do this by subtracting -2x from 2x and proceed to move it to the other side.
This would be result in: [tex]2y=-2x+20[/tex]
Next, we need to isolate the "y" variable by dividing the 2 off of it.
What you do to one side you do to the other!
-2 / 2 is -1 so this will just be "-x"
20 / 2 is 10
Therefore, our resulting equation will be: [tex]y = -x+10[/tex]
I hope this helped! Feel free to ask questions if you feel the need!

a line passes through the point (8,-3)and has a slope of 3/4
Answer:
[tex]y=\frac{3}{4}x-9[/tex]
Step-by-step explanation:
We are using the general equation of a straight line, which is
y=mx+b, where y&x are the coordinates, m is the slope and b is the y intercept. We are trying to solve for b, so we can plug in these values that we know into the formula in order to find b:
[tex]-3=\frac{3}{4}(8)+b\\-3=6+b\\-3-6=b\\b=-9\\\\y=\frac{3}{4}x-9[/tex]

The owner of a large restaurant is considering a new “no tipping” policy and wants to survey a sample of employees. The policy would add 20% to the cost of food and beverages and the additional revenue would be distributed equally among servers and kitchen staff.
A) The strata to be used in this survey by the employer is; Type of Staff
B) Stratified Random Sampling will be preferred because the opinions of the staffs on the tipping policy may be the same within each type but differ across the different types of staffs.
A stratified random sampling is a type of sampling that divides a population into groups known as strata.Now, from the question, we see that after adding a 20% to the cost of food and beverages, that the additional revenue will be distributed equally among the kitchen and server staffs.
This means the strata here will be the type of staff because the opinions of the staffs on the tipping policy may be the within each type but differ across both types of staffs.

How do you do the inverse of this function?
9514 1404 393
Answer:
f^-1(x) = <see attachment>
Step-by-step explanation:
If we write the function as ...
f(x) = ∛x +101/128x
Then the inverse function is the value of y when ...
x = f(y)
This resolves to a cubic in y, whose solution can be found by use of any of the various cubic solution formulas. You can find the cubic by ...
x = ∛y +by . . . . . . where b = 101/128
x -by = ∛y . . . . . . . subtract by
(x -by)³= y . . . . . . cube both sides
If we subtract the left side and expand the cube, we get ...
b³y³ -3b²xy² +(1 +3bx²)y -x³ = 0 . . . . . . . a cubic in y
There will be one real and two complex solutions to this cubic. The real solution can be written in the form shown in the attachment. That is, ...
y = f⁻¹(x) = [attachment expression]
A graph of it is shown in the second attachment. It is the reflection of f(x) across the line y = x, as an inverse function should be.

Additional comment
The idea here is to show that it is possible to write an expression for the inverse function. It is not pretty, and it is somewhat tedious to evaluate.
The length of a rectangle is 7 feet less than four times with width. The Perimeter of the
rectangle is 146 feet. Find the length and width of the rectangle. ( P = 2L +2W)
Answer:
Step-by-step explanation:
p = 2L+ 2W
length
(7-4)
3 feet
p = 2L+ 2W
146 = 2*3 + 2* w
146 = 6 + 2w
146-6 = 6-6 +2w
140 = 0+ 2w
140 = 2w
70 feet = w
width is 70 feet
p= 2L+2W
146 = 2*a +2* 70
146 = 2a + 140
146-140 = 2a + 140-140
6 = 2a
3 feet = a
length is 3 feet
width is 70 feet.

What is transposing a term in an expression or transpose method?To bring a term from one side of an equation to the other, with corresponding change in sign or by doing opposite operations is called transposing a term in an expression.
According to the given question.
We have a formula for the volume of cone
[tex]V = \frac{1}{2} \pi r^{2} h[/tex]
To solve the the above formula for r we use transpose method.
Therefore,
[tex]V = \frac{1}{2} \pi r^{2} h[/tex]
⇒ [tex]2V = \pi r^{2}h[/tex] (multiplying by 2 both the sides)
⇒ [tex]\frac{2V}{\pi h} =r^{2}[/tex] (dividing both the sides by πh)
⇒ [tex]r=\sqrt{\frac{2V}{\pi h} }[/tex]
Hence, the given formula for the volume of cone can be written as [tex]\sqrt{\frac{2V}{\pi h} }[/tex] in terms of V and h for r.

A certain town is clustered around the town's largest employer, a paper mill. A researcher notices a large number of children with asthma and suspects the proportion of children with asthma in this town may be larger than the nationwide proportion of 7%.
(a) (2 pts) Write the null and alternative hypotheses.
(b) (3 pts) Suppose the researcher committed a Type I error. What did the researcher conclude and what was the reality regarding children with asthma?
(c) (3 pts) Suppose the researcher committed a Type II error instead. What did the researcher conclude and what was the reality regarding children with asthma?
Using statistical concepts, it is found that:
a)
The null hypothesis is: [tex]H_0: p \leq 0.07[/tex]
The alternative hypothesis is: [tex]H_0: p > 0.07[/tex]
b)
The type I error means that the researcher concluded that the proportion in this town was above 7%, while in reality it wasn't.
c)
The type II error means that the researcher concluded that the proportion in this town was not above 7%, while in reality it was.
Item a:
At the null hypothesis, we test if the proportion is the nationwide proportion of 7% of less, thus:
[tex]H_0: p \leq 0.07[/tex]
At the alternative hypothesis, we test if the proportion is larger than the nationwide proportion, that is:
[tex]H_1: p > 0.07[/tex]
Item b:
A Type I error happens when a true null hypothesis is rejected.
Thus, the type I error means that the researcher concluded that the proportion in this town was above 7%, while in reality it wasn't.
Item c:
A Type II error happens when a false null hypothesis is not-rejected.
Thus, the type II error means that the researcher concluded that the proportion in this town was not above 7%, while in reality it was.

"Sierra has recipe she wants to make. She has to use eggs and sticks of butter. The ratio for these ingredients is 12 to 4 batches. What will the equivalent ratio be if she wants to make 8 batches"
"What is she wants to make 2 batches"
please help me get my grade up by answering this question I'll mark brainliest whoever answers first!<3
Answer:
24:8
Step-by-step explanation:
Given the following data;
Batch = eggs + sticks of butter
4 batches = 12:4
8 batches = 2 * 4 batches
Therefore, 8 batches = 2*(12:4)
8 batches = 24:8
Hence, the equivalent ratio Sierra would use if she wants to make 8 batches is 24 eggs to 8 sticks of butter.
