Answer:
y=1/5x+5
Step-by-step explanation:
Slope-intercept form is written y=mx+b.
y- needs to be by itself in this form.
m- the slope.
x- always to the right side of the slope, or m.
b- y-intercept.
Now that we know this, all we have to do is plug in the numbers we have. So when we plug this in, the equation looks like this:
y=1/5x+5
Hope this helps you and have a great day :3
Two conditions under which we can assume that the sample means follow a normal distribution are as follows:
1). If the sample size is large enough, n greater than or equals 30, the sampling distribution is approximately normal regardless of the shape of the population.
2). In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean.

Answer:
133.33%
Step-by-step explanation:
120= 120/90
the word OF = multiplication
120/90 x 100/100=133.33/100
133.33/100=133.33%
Answer:
16.9 m
Step-by-step explanation:
Start with a half a circle. The central angle of a semicircle is 180 deg.
Now subtract 21 deg on each side.
180 - 21 - 21 = 138
The central angle is 138 deg.
The radius is 7 m.
Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.
