Answer:
Hello the answer is
diameter = 49cm;
radius = diameter/2 = 24.5cm;
circumference = 2πr ≈ 153.94 = 154cm
1 revolution = 154cm
50 revolution = 7700cm = 77m
I hope I am correct. also please mark brainliest
Step-by-step explanation:
I found the missing choices:
<span>the standard deviation
the margin of error
the variance
the population mean
</span>
<span>The absolute difference between either limit and the mean is an example of THE VARIANCE.
Variance is defined as the</span><span> average of the </span>squared<span> differences from the Mean. </span>
If you want the answer in point slope form then,
y-y1 = m(x-x1)
y-c = m(x-a)
---------------------------------------
If you want the answer in slope intercept form, then solve for y
y-c = m(x-a)
y-c = mx-ma
y-c+c = mx-ma+c
y = mx-ma+c
y = mx+c-ma
y = mx+(c-ma)
For this answer in slope intercept form the slope is m and the y intercept is c-ma
---------------------------------------
If you want the answer in standard form, then get the variable terms to the left side. Have the constant terms on the right side.
y = mx+c-ma
y-mx = mx+c-ma-mx
-mx+y = c-ma
Optionally you can multiply both sides by -1 to get mx-y = -c+ma but it will depend on your book if this step is carried out or not.
Answer:
54 keys
Step-by-step explanation:
If there are 6 keys on each of the nine key rings, you times 6 by 9 to get 54.
<h3><u>The length is equal to 13.</u></h3><h3><u>The width is equal to 8.</u></h3>
l = 2w - 3
2l + 2w = 42
Because we have a value for l, we can plug it into the second equation to solve for w.
2(2w - 3) + 2w = 42
Distributive property.
4w - 6 + 2w = 42
Combine like terms.
6w - 6 = 42
Add 6 to both sides.
6w = 48
Divide both sides by 6.
w = 8
Now that we have a value for w, we can solve for the exact value of l.
l = 2(8) - 3
l = 16 - 3
l = 13
