For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 33 beats per minute, the mean of the l

isted pulse rates is x= 73.0 beats per minute, and their standard deviation is s = 23.8 beats per minute.
a. What is the difference between the pulse rate of 33 beats per minute and the mean pulse rate of the females?
b. How many standard deviations is that [the difference found in part a?
c. Convert the pulse rate of 33 beats per minutes to a z score.
d. If we consider pulse rates that convert to z scores between - 2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 33 beats per minute significant?​

What is the measure of one angle of a regular convex 20-gon
Contact [7]

Answer:

The measure of one angle of a regular convex 20-gon is 162°

Step-by-step explanation:

* Lets explain how to solve the problem

- A convex polygon is a polygon with all the measures of its interior

 angles less than 180°

- In any polygon the number of its angles equal the number of its sides

- A regular polygon is a polygon that is all angles are equal in measure

 and all sides are equal in length

- The rule of the measure of an angle of a regular polygon is

 m=\frac{(n-2)180}{n}, where m is the measure of each interior

 angle in the polygon and n is the numbers of the sides or the angles

 of the polygon

* Lets solve the problem

- The polygon is convex polygon of 20 sides (20 angles)

- The polygon is regular polygon

∵ The number of the sides of the polygon is 20 sides

∴ n = 20

∵ The polygon is regular

∴ All angles are equal in measures

∵ The measure of each angle is m=\frac{(n-2)180}{n}

∴ m=\frac{(20-2)180}{20}

∴ m=\frac{(18)180}{20}

∴ m=\frac{3240}{20}

∴ m = 162

∴ The measure of one angle of a regular convex 20-gon is 162°

Carl ran around the track 3 more times than Daria and 2 fewer times than Erin. When they were done they added up the number of l
Paul [167]

Answer:

Total laps = 10d

Step-by-step explanation:

Let c = Carl's laps

d = Daria's laps

e = Erin's laps

c = 3d

c = e/2

c + d + e = totals laps

We can insert 3d in place of c in the third equation

3d + d + e = total laps

Also, e/2 equals 3d

e/2 = 3d

Multiply both sides by 2

(e/2 = 3d)2

e = 6d

Insert the new e

3d + d + 6d = 10d = totals laps
