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]

(x,y) → (x + 6, y - 6); (1, -5)

(x, y) + (x + 6, y + 6); (1,7)

Answers

Answer:

B. (x, y) (x - 6, y - 6); (-11,-5)

Step-by-step explanation:

Given the vertices of a rectangle are R(-5, -5), S(-1,-5), 7(-1, 1), and U(-5, 1). After translation, the coordinate R' is at the point (-11, -11), in order to know the translation factors used;

Let (x, y) be the translation coordinate added to the original coordinate R to get R'. To get the coordinate (x, y)

(x, y)+(-5, -5) =(-11, -11)

x - 5 = -11

x = -11+5

x = -6

Similarly;

y-5 = -11

y = -11+5

y = -6

Hence the coordinates added to initial vertices is (-6, -6)

To get the new coordinate U' after translation, we will add the coordinate (-6, -6) to the U(-5, 1) as shown;

(x, y) + (-5, 1) = (-6, -6)+(-5, 1)

= (-6-5, -6+1)

= (-11, -5)

Hence the coordinates of U' is (-11, -5) and the translation rule is (- 6+ x,  -6+y) where (x, y) is (-6, -6).

Based on the above calculation, it can be seen that (x, y) (x - 6, y - 6); (-11,-5) is correct.

What is the equation for this line?

Answers

Answer:

The equation of the line is y = 2x - 3

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

m is the slope of the line,  [tex]m=\frac{y2-y1}{x2-x1}[/tex] b is the y-intercept (value y at x = 0)

Let us take two points on the line to find its equation

∵ Points (3, 3) and (0, -3) lie on the line

x1 = 3 and y1 = 3

x2 = 0 and y2 = -3

→ Use the rule of the slope above to find m

∵ [tex]m=\frac{-3-3}{0-3}=\frac{-6}{-3}=2[/tex]

m = 2

→ Substitute its value in the form of the equation above

∴ y = 2x + b

∵ b is the value of y at x = 0

∵ y = -3 at x = 0

b = -3

→ Substitute it in the equation above

∴ y = 2x + -3

→ Remember (+)(-) = (-)

∴ y = 2x - 3

The equation of the line is y = 2x - 3
