Find the surface area of this prism and explain how and FINAL EXAMS tomorrow HELP!!!!!!!! Please

Answers

surface area formula of a prism is:
S.A = 2 × Area of base + Perimeter of base × Height of prism
So the given are:
5 cm, 2 cm, and 3 cm

The base is an equilateral triangle
So the base is 3 cm and height is 2 cm
and we know the area of a triangle is:
A = (1)/(2)bh
P = add all sides together

Substitute them:
S.A =  2 × (1)/(2)(3)(2) + (3 + 3 + 3) × 5
       = 6 + 45
       = 51 cm²

Evelyn goes to a middle school that includes grades 6, 7, and 8. She wants to estimate the percentage of students in the school who ride the bus to school. She selects a random sample of 200 students to survey who are attending an after-school activity.

B. The sample might not be representative of the population because it only includes students who are attending an after-school activity.
I personally, would choose B.

The table shows the growth, in centimeters, of plants in two different soils after two weeks.Which statement explains which soil tended to have a greater growth?

Soil A had greater growth because its data have a greater standard deviation.
Soil A had greater growth because its data have a greater mean.
Soil B had greater growth because its data have a greater interquartile range.
Soil B had greater growth because its data have a greater median.

Answers

Answer:

Step-by-step explanation:

Given is a table about plants growth in soil A and B.

Let us find mean and median.

Soil A

Mean: 4.17

Median: 3.9

Mode: 3.5

Minimum: 3.1

Maximum: 6

Range: 2.9

Count: 10

Sum: 41.7

Soil B

Mean: 4.28

Median: 4.25

Mode: 3.9

Minimum: 2.9

Maximum: 5.5

Range: 2.6

Count: 10

Sum: 42.8

Soil B shows a better growth since both mean and median are greater.

it Might be D. Soil B had greater growth because its data have a greater median.
