A shoe store orders shoes from the manufacturer and sells them at a mall. Storing shoes at the store costs $3 per shoe pair for a year. When reordering shoes from the manufacturer, there is a fixed cost of $25 per order as well as $5 per shoe pair. The retail store sells 4500 shoe pairs each year. Find a function that models the total inventory costs as a function of x x the number of shoe pairs in each order from the manufacturer.

Answers

Answer:

the function that models the total inventory costs as a function of x is;

$( [tex]\frac{112500}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

Step-by-step explanation:

Given the data in the question;

cost of storing the shoes ( Holding cost ) = $ 3 per year

ordering cost ( Co ) fixed = $ 25 per order

cost of each pair = $ 5 per shoe pair

Total demand = 4500 shoe pairs

Total Inventory cost = Holding cost Ordering cost

so

Total Inventory cost = [tex]\frac{4500}{x}[/tex]( $ 25) + [tex]\frac{1}{2}[/tex]× $3 × x

Total Inventory cost = $( [tex]\frac{4500*25}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

Total Inventory cost = $( [tex]\frac{112500}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

Therefore, the function that models the total inventory costs as a function of x is; $( [tex]\frac{112500}{x}[/tex] + ([tex]\frac{3}{2}[/tex])x )

An ANOVA procedure is applied to data obtained from 6 samples where each sample contains 10 observations. The degrees of freedom in the denominator for the critical value of F test statistic is Group of answer choices

Answers

Answer:

The degree of freedom in the denominator = 114

Step-by-step explanation:

For Analysis of Variance procedure :

The number of groups, k is the number of distinct groups = 6

The total number of samples, N = number of groups multiplied by the number of samples per group ; N = 20 * 6 = 120

Degree of freedom (df) :

dfwithin = df of numerator = k - 1 = 5

df between = df of denominator = N - k

df denominator = 120 - 6 = 114

USF is interested in learning about the average time students spend taking selfies. The university sampled 38 students and asked each to provide the amount of time they spent taking selfies. This variable, selfie time, was then used to conduct a test of hypothesis. The goal was to determine if the average selfie time for all USF's students differed from 20 minutes. Suppose the large-sample test statistic was calculated to be z = 2.14. Find the p-value for this test of hypothesis.

Answers

Answer:

the p-value for this test of hypothesis is 0.0324

Step-by-step explanation:

Given the data in the question;

sample size n = 38

Null hypothesis             H₀ : μ = 20

Alternative hypothesis Hₐ : μ ≠ 20

z = 2.14

Test Statistic;

since its a two tailed test, p-value will be;

⇒ 2 × P( Z > |z| )

= 2 × ( 1 - P( Z < |z| ) )

we substitute in the value of z

= 2 × ( 1 - P( Z < 2.14  ) )

from z score table, P( Z < 2.14 ) = 0.9838

= 2 × ( 1 - 0.9838 )

= 2 × ( 0.0162 )

P-value = 0.0324

Therefore, the p-value for this test of hypothesis is 0.0324

Each degree of comparison has its own suffix
The positive degree of comparison simply modifies the word and has no suffix
The comparative degree compares two things and uses the suffix –est
The superlative degree compares three things and uses the suffix -est

Answers

Answer:

Each degree of comparison has its own suffix..

Both the adjectives and adverbs are used to make comparisons. The comparatives and superlatives are also used in writing to hedge or to boost the language. Each degree of comparison has its own suffix. The correct option is A.

What is comparative degrees?

The comparative form is used to compare two people, ideas or things. The superlative form with the word 'the' is used to compare three or more. The comparative adjectives are used to compare differences between the two objects they modify (larger, smaller, faster, higher).

The comparative form is used in the sentence where two nouns are compared. The comparative adjectives compare one person or the thing with another and enable us to say whether a person or thing has more or less of a particular quality.

One example of comparative adjective is that Josh is taller than his sister.

Thus the correct option is A.

According to the Pythagoras theorem,

a² + b² = c²

3² + b² = 5²

9 + b² = 25

b² = 25 - 9

b² = 16

b = 4m

The height of six trees in a parkway are 5 meters, 8 meters, 12 meters, 6 meters, 11 meters, and 5 meters. Find the mean height of the six trees. A. 7 meters B .7.83 meters C.8.21 meters D.12 meters​

Answers

Answer:

The answer is B, 7.83 meters.

Step-by-step explanation:

The mean of the six trees refers to the average height of all six trees. To find the mean value of any set of values, simply follow this formula:

Mean = [tex]\frac{Sum of all values}{Number of values you used}[/tex]

So for this particular question, my working was:

Mean = (5m + 8m + 12m + 6m + 11m + 5m)/6 = 7.833333333333m (Round off to 3 significant figures to get 7.83m)

For this, in basic terms, is asking for the two areas, of each shape, and then add those two together.

So, for the square:

A = Length • Width
A = 8•8
A = 64

Then, for the triangle:
A = 1/2 • Base • Height
A = 1/2 • 6 • 8
A = 3 • 8
A = 24

Finally:
64 + 24 = 88

The final answer is 88 ft^2

Charlotte thinks of a number.
She increases it by one fifth, and then reduces that answer by one half.
She finishes with 39.
What number did she start with?

Answers

Answer:

Charlotte started with 65.

Step-by-step explanation:

In order to find what number Charlotte started with, we need to go backward. So first, multiply by 2, then multiply by 5/6. 39 multiplied by 2 is 78, which is 6/5 of the number Charlotte started with. So what we need to do is multiply 78 by 5/6. That equals 390/6, which is 65. The problem has been solved. Charlotte started with 65.

Answer:

Start: x = 141°

141° and x are alternate interior angles and congruent because the lines are parallel

Go left: x = 39°

39° and x are corresponding angles, and therefore congruent

Go down: x = 139°

180 - 41 = 139, the angle next to 41 and x are corresponding angles

Go left: x = 98°

180 - 82 = 98, the angle next to 82 and x are corresponding angles

Go down: x = 102°

102° and x are vertical angles and therefore congruent

Go right: x = 50°

180 - 130 = 50, the angle next to 130 and x are corresponding angles

Go down: x = 74°

corresponding angles

Go right: x = 83°

corresponding angles

Go right: x = 95°

corresponding angles

Go up: x = 18°

corresponding angles

Go left: x = 166°

180 - 14 = 166, consecutive interior angles are supplementary (I'm confused? none of the answers have it but they're definitely consecutive interior...)
