Answer:
C. 12
Step-by-step explanation:
Corresponding sides are proportional. Sides with the same mark are the same length.
WX/XY = LM/MN = LM/KJ
WX/10 = 18/15
WX = 180/15 . . . . multiply by 10
WX = 12

PLEASE I NEED HELP!! what are two ways that you can tell that two ratios form a proportion? i really need to pass this test to get my grades up, I'm not trying to cry my whole winter break.
Answers
Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."
Step-by-step explanation:
Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fraction in it’s simplest form. Another way is to see if the numbers in the ratios are factors or multiples of each other. For example, 10:5 and 30:15. 10:15= 10/5 and 30:15= 30/15. Then you put it in simple form. 10/5 = 2 and
30/15 = 2. Therefore 10:5 and 30:15 are proportional.

So first we need to go to a graphing calculator! I usually use Desmos to do my stats stuff. You'll wanna head to their linear regression calculator (I can't add a link, but just google Desmos linear regresion and it'll pop up).
Put the points into the table. Lines of best fit have the equation y1 ~ bx1+a, so put that in the box right below the table, where you see another equation already written- just edit it. We see all the other numbers listed below that, so we know that b=-0.894 and a=13.599, so the line of best fit is -0.9x + 13.6 = y when you round those numbers.
The correlation coefficient is represented by the letter r. r is shown below as well, and is -0.964. Strong correlations are represented by a value close to the number 1, so this is strong, as it's very close. It is negative because of its sign. Correlation coefficients don't go over the number 1 or below -1, so be careful. I hope this was helpful! If you need any more clarification just let me know.

What is the product of two fractions?The product of two fractions is the product of the numerators and the product of the denominators.
Product of two fractions = Product of their denominators / Product of their numerators.
Twenty hundredths = 20/100
Sixty-five thousandths = 65/1000
Product = 20/100 × 65/1000
= 2/10 × 65/1000
= 130/10000
= 13/1000
= 0.013
Therefore, the product of twenty hundredths and sixty-five thousandths is 0.013.

Holly has $225 to spend at the shopping mall. She decides to buy sweaaters and pants with her money. Sweaters cost $45 each and pants cost $25 each. The equation 45s + 25p = 225 represents this situation.
If Holly buys 3 sweaters, what is the greatest number of pants she can buy?
Answers
Answer:
3 pairs of pants
Step-by-step explanation:
Plug 3 in for s. Your equation should now be 45(3) +25p=225
Then distribute 135+25p=225
Subtract 25p=90
Divide p=3.6
Since you cannot buy half of a pair of pants you need to round down to three

please help fast, will give brainliest
Answers
Answer:
1.5sin4x
Step-by-step explanation:
I just answered this question and got it right.
The function is 1.5sin(4x).
What is sin function?The ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle is the sine function in trigonometry. A right triangle's sides or unknown angles can be found using the sine function.
Given the sine function from (0, 2π), and amplitude is 1.5, the period is π/2
sine function in general form
y = a sin (b (x – h)) + d
where a = amplitude, b= period
h is the phase shift, and
d is the vertical displacement.
according to question, This function currently has no phase shift, since
h = 0, and no vertical displacement, since d = 0
equation is y = a sin b x
and b is ratio of normal period to desired period
b = 2π/(π/2)
b = 4
substitute the value of a and b in equation we get,
y = 1.5 sin (4x)
Hence the sin function from 0 to 2pi is y = 1.5 sin (4x).

Answers
Given:
The regression equation for change in temperature, y, to amount of rain, r, is given by
[tex]\hat{y}=0.2-1.4r[/tex]
The observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.
To find:
The residual and interpret it.
Solution:
According to the question, the observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.
So, the actual value is 2.3 degrees.
Put r=0.4 in the given equation, to find the predicted value.
[tex]\hat{y}=0.2-1.4(0.4)[/tex]
[tex]\hat{y}=0.2-0.56[/tex]
[tex]\hat{y}=-0.36[/tex]
We know that,
Residual = Actual value - Predicted value
[tex]Residual=2.3-(-0.36)[/tex]
[tex]Residual=2.3+0.36[/tex]
[tex]Residual=2.66[/tex]
Residual is positive because predicated value is less than the actual value.
So, the regression line underpredicts the temperature change.
Therefore, the correct option is B.
