Consumer complaints are frequently reported to the Better Business Bureau. Industries with the most complaints to the Better Bus

kiruha [24]

Answer:

(a)

$\begin{array}{ccc}{Industry} & {Frequency} & {\%Frequency} & {Bank} & {26} & {13\%} & {Cable} & {44} & {22\%} & {Car} & {42} & {21\%}& {Cell} & {60} & {30\%} & {Collection} & {28} & {14\%} & {Total} & {200} & {100\%} \ \end{array}$

(b): Cell industry

(c) See Explanation

Step-by-step explanation:

Given (Missing from the question)

$Bank = 26$

$Cable = 44$

$Car = 42$

$Cell = 60$

$Collection = 28$

$Total = 200$

Solving (a) Show the frequency and percent frequency.

The percentage frequency is calculated by:

$\%Freq = \frac{Freq}{Total} * 100\%$

So. we have:

$\%Freq = \frac{26}{200} * 100\% = 13\%$ -- Bank

$\%Freq = \frac{44}{200} * 100\% = 22\%$ --- Cable

$\%Freq = \frac{42}{200} * 100\% = 21\%$ --- Car

$\%Freq = \frac{60}{200} * 100\% = 30\%$ --- Cell

$\%Freq = \frac{28}{200} * 100\% = 14\%$ --- Collection

The table becomes:

$\begin{array}{ccc}{Industry} & {Frequency} & {\%Frequency} & {Bank} & {26} & {13\%} & {Cable} & {44} & {22\%} & {Car} & {42} & {21\%}& {Cell} & {60} & {30\%} & {Collection} & {28} & {14\%} & {Total} & {200} & {100\%} \ \end{array}$

Solving (b): The industry with the highest complaints

From the above table, the highest frequency is 60 and this represents the number of complaints of Cell industry.

Hence, the cell industry has the highest number of complaints

Solving (c): Comment

The percentage frequency table shows that the industry with the highest number of complaints is the cell industry (at 30%) and the industry with the least is the banking industry (at 13%)

The volume of a cylindrical bucket is 4019.2 cubic inches. Find the height of the bucket if the base area is 200.96 sq. Inches?

natita [175]

Answer:

20

Step-by-step explanation:

Formula

V = B * h

Givens

B = 200.96 square inches

V = 4019.2 cubic inches

Solution

4019.2 = 200.96 * h Divide by 200.96

4019.2/200.96 = h

h = 20 inches

The sum of the measures of two complementary angles exceeds the difference of their measure by 86º. Find the measure of each ang

katrin2010 [14]

We will translate the given statement in the problem into
x + y = 90
x - y = 90 - 86 = 4 where x and y are the angles that are complementary. solving simultaneously, x = 47 degreesy = 43 degrees.

Help pls!!<br><br> Use 3.14 for pi.

krok68 [10]

<h3>Find the area of the circle</h3>

To find the area, we take into account that your data is:

r = 6 cm
π = 3.14

To calculate the area of the circle, we use the following formula:

Area: π * r²

We substitute the data in the formula, and we begin to solve.

A = 3.14 * (6 cm)²

taking the square root

A = 3.14 * 36 cm²

Multiply the two numbers

A = 113.04 cm²

Therefore, the area of the circle is 113.04 cm². The correct alternative is option "A".
