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.
Answer:
57 °
Step-by-step explanation:
Complementary angles = 90 °
Since, Your angle don't have ∠ [ ] Then Let let "C" and "y"
Thurs, C = 12x- 3 and y = 7x - 2
It is given that angles r and s are complementary angles. Two angles are complementary if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,
c + y = 90
12x - 3 + 7x - 2 = 90
19x - 5 = 90
19x = 95
x = 95/19
x = 5
Using the value of x in expression or r, we get:
c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.
So measure of angle c is 57 degrees.
Hence, the ∠ is 57 °
