Answer/Step-by-step explanation:

1. To find the area of the shaded region, you'd find the area of the white rectangular shape, next, find the area of the whole triangular shape, then find the difference of their areas to get the area of the shaded region. Thus, the formula to use would be:

Area of shaded region = area of triangle - area of rectangle

Area of shaded region = ½*base*height - length*width

1. a. Volume of triangular prism = area of triangular base * height of prism

Volume of triangular prism = ½bh * H

Where,

b = 6 m

h = 4 m

H = 8 m

Substitute

Volume of prism = ½*6*4*8

Volume of prism = 96 m³

b. Volume of sphere = ⁴/3πr³

Where,

r = 9 cm

Substitute

Volume = ⁴/3*π*9³

Volume = ⁴/3*π*729

Volume ≈ 3,053.6 cm³ (nearest tenth)

2. Use Pythagorean theorem to find the height of the cone

radius of the cone (r) = ½(16) = 8 cm

Slant height (l) = 11 cm

height (h) = ?

Using Pythagorean theorem, we have:

h = √(l² - r²)

Substitute

h = √(11² - 8²)

h = √(57)

h ≈ 7.5 cm (nearest tenth)

b. Volume of the cone = ⅓πr²h

where,

r = 8 cm

h = 7.5 cm

Volume = ⅓*π*8²*7.5

Volume = 502.7 cm³ (nearest tenth)

Select the correct function that represents this data

Hoochie [10]

Answer: A

Sustitute one of the inputs into all of the equations and see if you get the respective output. I will use the point (0,2).

A. f(0)=8(0)+2

f(0)=2

Option A works!

B. f(0)=8(0)-2

f(0)=-2

Option B doesn’t work.

C. f(0)=8(0)

f(0)=0

Option C doesn’t work.

Since option A is the only one that works, the correct function is A.

Question 5 Buying a year's worth of textbooks for college can be expensive! Consider a large population of college students for

Furkat [3]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data :

Minimum 80

Quartile 1 (Q) 215

Median 335

Quartile 3 (Q3) 380

Maximum 440

Population IQR

IQR = Q3 - Q1 = 380 - 215 = 165

A.)

Dot at 240

The dot plot shows the sample distribution of interquartile range, hence, all the points on the plot represents the interquartile range for 50 different samples.

Hence, the dot at 240 represent the interquartile range value of one of the 50 sample distributions.

B.)

According to the sampling distribution chart, the graph form a bell shaped curve and loos fairly symmetric, hence we could conclude thatvthe mean IQR of the sampling distribution is about 165.

Since population IQR is also 165 ; we can conclude that sampling distribution OF IQR is an unbiased estimator of population IQR.
