You operate a fresh fruit and vegetable market. For normal shipments, about 9.0% of the peaches are spoiled when they reached yo

Nastasia [14]

Given:

Spoilage rate of fruits = 9% = 0.09

To find:

Amount of fruits to be order to have 100 pounds of peaches and considering the spoilage rate.

Solution:

Let the required amount of fruits you should order be x.

So, spoiled fruits = 9% of x = 0.09x

He would like to have 100 pounds of peaches to sell.

$x-0.09x=100$

$0.91x=100$

Divide both sides by 0.91.

$x=\dfrac{100}{0.91}$

$x=109.89$

$x\approx 110$

The required amount of fruits to be order is 110 lbs. Therefore, the correct option is D.

Answer:

Step-by-step explanation:

Corresponding fuel efficiencies of manufacturer A's car and manufacturer B's car form matched pairs.

The data for the test are the differences between the efficiencies of manufacturer A's car and manufacturer B's car

μd = fuel efficiency of manufacturer A's car minus the fuel efficiency of manufacturer B's car.

Sample mean, xd

= (4 + 5 - 1 + 2 + 1 + 4 + 3 - 2)/8 = 2

xd = 2

Standard deviation = √(summation(x - mean)²/n

n = 8

Summation(x - mean)² = (4 - 2)^2 + (5 - 2)^2 + (- 1 - 2)^2 + (2 - 2)^2 + (1 - 2)^2 + (4 - 2)^2 + (3 - 2)^2 + (- 2 - 2)^2 = 44

Standard deviation = √(44/8

sd = 2.35

For the null hypothesis

H0: μd = 0

For the alternative hypothesis

H1: μd ≠ 0

This is a two tailed test and the distribution is a students t. Therefore, degree of freedom, df = n - 1 = 8 - 1 = 7

2) The formula for determining the test statistic is

t = (xd - μd)/(sd/√n)

t = (2 - 0)/(2.35/√8)

t = 2.41

We would determine the probability value by using the t test calculator.

p = 0.047

Since alpha, 0.1 > the p value 0.047, then we would reject the null hypothesis. Therefore, at 1% significance level, we can conclude that there is a significant difference in the mean MPG (miles per gallon) when testing for the fuel efficiency of these two brands of automobiles.

Ajay analyzed two companies and has formulated tables to model each company’s growth, where x represents the age of the companie

Juliette [100K]

From year 1 to year 2, Company 1 added 6 employees (went from 6 to 12).

From year 1 to year 2, Company 2 multiplied the number of employees by 6 (went from 6 to 36).

The appropriate description is the last one ...

... company 2 because it is multiplying its number of employees by six each year while company 1 is adding 6 employees each year

_____

Multiplying by 6 each year causes the numbers to increase much faster (as you can tell by looking at the tables). Since the investment choice depends on larger numbers of employees, <em>Company 2</em> is the better choice.

Sergeu [11.5K]

This question is incomplete because it lacks the appropriate figure. Find attached to this answer the diagram of the figure.

Answer:

8%

Step-by-step explanation:

The formula for Probability =

Numbers of possible outcomes ÷ Number of events.

From the diagram, Number of Possible outcomes is given as = Number of Adults that prefer auto racing = 179 adults

Number of events is obtained from the questions as the Number of Adults = 2237 adults

Probability that an adult chosen at random prefers auto racing = 179 adults /2237 adults

= 0.0800178811

Rounding my answer to the nearest whole percent, the probability that an adult chosen at random prefers auto racing

= 0.0800178811 × 100

= 8%
