ANSWER:
STEP-BY-STEP EXPLANATION:
Hi,
The square root of √ 7 is 2,645751.
Given:
Scatter plot of weight loss plan.
To find:
how many pounds were lost per month with 4 hours of weekly.
Solution:
Take any two points on the trend line.
Let the points are (3, 4) and (5, 7).
Slope of the line:
m = 1.5
Using point-slope formula:
Add 4 on both sides.
Approximate equation of a line is y = 1.5x - 0.5
Substitute x = 4.
y = 1.5(4) - 0.5
y = 6 - 0.5
y = 5.5
Which is nearly equal to 6.
Also see in the scatter plot, y-value for the corresponding value of 4 in x-axis is 6.
Hence 6 pounds lost per month with 4 hours of weekly aerobic activity.
The answer should be 1/2
You should write out the rest of the problem if the app doesn’t scan it right so you can get an accurate answer.
Explanation:
Every time x goes up by 6, y goes up by 3
Rise/run
X=run
Y=rise
3/6
1/2
Hope this helps
Answer:
a/b = a * 1/b
Step-by-step explanation:
a/b = a * 1/b
this looks easy....
But what about
a / (1/b) = a*b
if you see any division, you can always multiply BOTH the numerator AND the denominator by the same amount. That is allowed because that is the same as multiiplying by the number 1.
So multiply by b/b and see what happens.
a / (1/b) = b/b * a / (1/b)
group the numerator AND the denominator
a / (1/b) = (b * a ) / b*(1/b)
a / (1/b) = (b * a ) / b/b
a / (1/b) = (b * a ) / 1
a / (1/b) = (b * a )
a / (1/b) = a*b
It is allowed because you can always multiply any number by 1 and that is because that will not change the original number. The number multiplied by 1 remains the same number.
This notion is very powerful and it can be used to turn any division into a multiplycation, and vice versa.
a / (1/b) = a*b
