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.

Step-by-step explanation:
Answer: 116 degrees.
Step-by-step explanation:
Interior angles of a triangle add to 180.
Knowing the first two angles are 36 and 28, you can subtract them from 180 to find the answer:
180 - 36 - 28 = 116
Answer:
The predicted calories would be 403 calories.
Step-by-step explanation:
We have a linear regression model relating y: calories with x: carbohydrates, which has a slope of 4.0 and a y-intercept of 3.0.
Then, the model equation is:

With these model we can predict the calories values for any amount of carbohydrates, within the interval within which this model is valid.
If a new food is tested, and the number of carbohydrates (x) is 100, the predicted value will be:

The predicted calories would be 403 calories.
Answer:
y^6
Step-by-step explanation:
a^b^c = a^(b*c)
We have y^2^3
y^(2*3) = y^6
