The editor of a textbook publishing company is deciding whether to publish a proposed textbook. Information on previous textbooks published show that 20 %20% are huge successes, 30 %30% are modest successes, 30 %30% break even, and 20 %20% are losers. Before a decision is made, the book will be reviewed. In the past, 99 %99% of the huge successes received favorable reviews, 60 %60% of the moderate successes received favorable reviews, 40 %40% of the break-even books received favorable reviews, and 30 %30% of the losers received favorable reviews. If the textbook receives a favorable review, what is the probability that it will be huge success?

Answers

Answer:

[tex]Probability = 0.198[/tex]

Step-by-step explanation:

Given

Publish

[tex]Huge\ Success = 20\%[/tex]

[tex]Modest\ Success = 30\%[/tex]

[tex]Break\ Even = 30\%[/tex]

[tex]Losers = 20\%[/tex]

Favorable Reviews:

[tex]Huge\ Success = 99\%[/tex]

[tex]Modest\ Success = 60\%[/tex]

[tex]Break\ Even = 40\%[/tex]

[tex]Losers = 30\%[/tex]

Required

Determine the probability that a textbook is huge success and favorable

To do this, we simply multiply the probability of a textbook being huge success and being favorably reviewed. as follows;

[tex]Probability = 20\% * 99\%[/tex]

[tex]Probability = 0.198[/tex]

Answer:

38.11 and 3.66

Step-by-step explanation:

The sample mean and standard deviation for the given data are 38.11 and 3.66 respectively.

What is the mean absolute deviation?

The average distance between an observation's mean and its variance is shown by the mean absolute deviation, a measure of variability. mean makes understanding simpler by using the data's original units. A wider deviation from the average is reflected by larger values. The mean absolute deviation is sometimes referred to as the average absolute deviation and the mean deviation.

The mean is the average of the data set and given by

Mean = sum of all the data sets/number of data set

Mean = (33 + 34 + 42 + 36 + 39 + 36 + 39 + 40 + 44)/9

Mean = 38.11

Now standard deviation is given by

[tex]s = \sqrt{\frac{1}{N-1} \sum_{i=1}^N (x_i - \overline{x})^2}[/tex]

Where N is the number of data while the x bar is the mean.

So by using the formula,

Standard deviation = 3.66.

Hence "The sample mean and standard deviation for the given data are 38.11 and 3.66 respectively".

StartRoot 20 EndRoot

StartRoot 40 EndRoot

StartRoot 45 EndRoot

StartRoot 58 EndRoot

Answers

Answer:

StartRoot 58 EndRoot

Step-by-step explanation:

Given the coordinates (-4, -3) and (-1, 4)

To get the distance between the two points, we will use the formula:

D =√(y2-y1)²+(x2-x1)²

From the coordinates, x1 = -4, y1 = -3, x2 = -1 and y2 = 4

Substitute

D =√(4-(-3))²+(-1-(-4))²

D = √(4+3)²+(-1+4)²

D = √7²+3²

D = √49+9

D = √58

Hence the correct option is D

A salesperson earns $8 per hour plus 6% commission on her sales. In a week when she worked 40 hours, her total earning were $692. What was the total amount of her sales for the week?

Answers

Answer:

The answer is $6216.66

Step-by-step explanation:

(8*40)+6%*×=$692; 320 + 0.6x = 692; .6×=692-320; 0.6x=373; ×=373÷.6;

x=6216.66

The total amount of the salesperson's sales for the week is $6,200

Total earnings= $692

Total hours worked = 40 hours

Earnings per hour = $8

Total hourly earnings = Total hours worked × Earnings per hour

= 40 hours × $8

= $320

Commission earnings = Total earnings - Total hourly earnings

= $692 - $320

= $372

Total amount of her sales for the week = x

6% of x = $372

0.06 × x = 372

0.06x = 372

x = 372 / 0.06

x = $6,200

Therefore, her total amount of her sales for the week is $6,200
