The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.

Answers

Complete question is in comment section :

Answer:

68%

Step-by-step explanation:

Mean = 25

Standard deviation = 5

The percentage of trees between 20 and 30

20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)

25 - 5 = 20

30 trees = 1 standard deviation above the mean ;

Mean + 1(standard deviation) ;

25 + 5 = 30

This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%

The measure of an angle is 2.8.what is the measure of its complementary angle

Answers

Answer:

87.2º

Step-by-step explanation:

Complimentary angles total 90º

c + 2.8 = 90

c = 90 - 2.8

c = 87.2º

Answer:

87.2°

Step-by-step explanation:

When angles are complementary, it means that they both add up to 90°.

In this case, one of the angles measures 2.8°.

So, to find the other one, we subtract 2.8 from 90.

90 - 2.8 = 87.2

The measure of the complementary angle is 87.2°

Explain how to find the quotient of 1/4 divided by 5

Answers

Answer:

1/20

Step-by-step explanation:

(1/4) / 5

When dividing a fraction by a whole number

multiply the divisor by the number

4 * 5 = 20

(1/4) / 5 = 1/20

Answer:

Convert 1/4 to decimal form, which is 0.25.Divide 0.25 by 5 The quotient is 0.05, or 1/20 in simplified fraction form

There is another way to solve without converting:

Set up equation like this: 1/4 x 1/5 (Use KCF if you know how to divide or multiply by fractions. If you don't, use the first method above)1/4 x 1/5 = 1/20The quotient is 1/20

A track is 400 yards around how many full laps does tyler need to run if he wants to run atleast 2 milies

Answers

Answer:

17.6 laps

Step-by-step explanation:

Total distance to be covered = 2 miles

distance coved in each lap = 400 yards

We know that 1 mile = 1760 yards

therefore, 4 miles will make = 4×1760

= 7040 yards.

Number of laps to be taken

= Total distance to be covered ÷ distance coved in each lap

= 7040/400 = 17.6 laps

Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?

Answers

Answer: 15 units

Step-by-step explanation:

Given

The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]

The length of the line segment is given by the distance formula i.e.

[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]

Insert the values,

[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]

Therefore, the length of line segment TU is 15 units
