Answer:

-3 +2 = -1

-5 +-1 = -6

6 + -4 = 2

-2 + -7 = -9

Step-by-step explanation:

This is very easy...if u need help on this just imagine the negative numbers as subtraction instead. So for example (This is very hard to explain lol) 6 + -4. Don't do 6 + 4. Do 6 - 4. That will equal 2 right? Ok, do the same to the rest. (Just use google for a better explanation lol. I'm not really good at explaining stuff lmbo) Hope this helps you even tho the other person answered. But, at least i helped you (Not really tho, lol)

The editor of a textbook publishing company is deciding whether to publish a proposed textbook. Information on previous textbook
kogti [31]

Answer:

34.86% probability that it will be huge​ success

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

P(B|A) = \frac{P(B)*P(A|B)}{P(A)}

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Receiving a favorable review.

Event B: Being a huge success.

Information on previous textbooks published show that 20 % are huge​ successes

This means that P(B) = 0.2

99 % of the huge successes received favorable​ reviews

This means that P(A|B) = 0.99

Probability of receiving a favorable review:

20% are huge​ successes. Of those, 99% receive favorable reviews.

30% are modest​ successes. Of those, 70% receive favorable reviews.

30% break​ even. Of those, 40% receive favorable reviews.

20% are losers. Of those, 20% receive favorable reviews.

Then

P(A) = 0.2*0.99 + 0.3*0.7 + 0.3*0.4 + 0.2*0.2 = 0.568

Finally

P(B|A) = \frac{P(B)*P(A|B)}{P(A)} = \frac{0.2*0.99}{0.568} = 0.3486

34.86% probability that it will be huge​ success

Approximately how many years will it take for the world’s population to increase to 8,252,000,000 people? Since there will be th
grin007 [14]

The number of years it will take for the world’s population to increase to 8,252,000,000 people is 16

<h3>How to determine the number of years?</h3>

This implies that we calculate the value of x

The equation is given as:

8252=(6080)(1.02)^x

Divide both sides by 6080

1.36 = (1.02)^x

Take the logarithm of both sides

log(1.36) = x * log(1.02)

Divide both sides log(1.02)

x = log(1.36)/log(1.02)

Evaluate the quotient

x = 16

Hence, the number of years is 16
