Answer:

Step-by-step explanation:

A triangle is made up of three line segments therefore, it would be impossible to make multiple triangles with only 3 line segments. You could stretch the line segments but they would never make other triangles since each attempt would be missing one line segment. What can be done with these 3 line segments is making more than one type of triangle. For example, we can make acute triangles, an obtuse triangle, right triangles, etc.

The body temperatures of a group of healthy adults have a bell-shaped distribution with a mean of 98.35°F and a standard deviati

DochEvi [55]

Answer:

a) 99.97%

b) 65%

Step-by-step explanation:

• 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

• 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

• 99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

Mean of 98.35°F and a standard deviation of 0.64°F.

a. What is the approximate percentage of healthy adults with body temperatures within 3 standard deviations of the mean, or between 96.43°F and 100.27°F?

μ - 3σ

98.35 - 3(0.64)

= 96.43°F

μ + 3σ.

98.35 + 3(0.64)

= 100.27°F

The approximate percentage of healthy adults with body temperatures is 99.97%

b. What is the approximate percentage of healthy adults with body temperatures between 97 .71°F and 98.99°F?

within 1 standard deviation from the mean - that means between μ - σ and μ + σ.

μ - σ

98.35 - (0.64)

= 97.71°F

μ + σ.

98.35 + (0.64)

= 98.99°F

Therefore, the approximate percentage of healthy adults with body temperatures between 97.71°F and 98.99°F is 65%

7. A seed company planted a floral mosaic

jenyasd209 [6]

Answer:

w = 160, L = 50

Step-by-step explanation:

Length = 50 feet

Width = 160 feet

First Find the Length

w = l + 110

P=2w+2l

420=2w+2l

420=2(l+110)+2l

420=2l+220+2l

4l=200

l=50

Finding the Width

w=(50)+110

w=160

A theater has n rows of seats and the number of seats in each row is 4 less than the number of rows. Which of the following repr

tiny-mole [99]

Answer:

The correct option is a) n(n-4).

Step-by-step explanation:

Consider the provided information.

Let n represents the number of rows.

The number of seats in each row is 4 less than the number of rows.

This can be written as: $n-4$

A theater has n rows of seats.

Therefore the total number of seats in the theater is:

$n(n-4)$

Hence, the correct option is a) n(n-4).
