let 'x' be the speed of the car. Hope this will helps:)
Step-by-step explanation:
Answer:
The measures of angle are 46 degrees and 134 degrees.
Step-by-step explanation:
We are given the following in the question:
Let the measure of one the of the supplementary angles be x degrees.
Measure of other angle =

Since, the two angles are supplementary, their sum is 180 degrees.
Thus, we can write and solve the equation:

Thus, the measures of angle are 46 degrees and 134 degrees.
The y-intercept of the linear equation of best fit, considering the slope and the means, is of -60.428.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For a line of best-fit, the y-intercept is given by:

The parameters in this problem are given as follows:

Then:

If 21 out of 24 students did their homework, 3 out of 24 did not do it.
This written as a fraction is 3/24 and can be reduced to 1/8.
This in decimal form is 0.125 .
To convert the decimal to a percent, multiply by 100 and put a percent sign at the end of the number.
0.125 × 100 = 12.5
12.5%
