Answer:

To be able to approximate the sampling distribution with a normal model, it is needed that $np \geq 10$ and $n(1-p) \geq 10$ , and both conditions are satisfied in this problem.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they will make payments on time, or they won't. The probability of a person making the payment on time is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The sampling distribution can be approximated to a normal model if:

$np \geq 10$ and $n(1-p) \geq 10$

Based on past experience, a bank believes that 8.9 % of the people who receive loans will not make payments on time.

This means that $p = 0.089$

The bank has recently approved 220 loans.

This means that $n = 220$

What must be true to be able to approximate the sampling distribution with a normal model?

$np = 220*0.089 = 19.58 \geq 10$

$n(1-p) = 220*0.911 = 200.42 \geq 10$

To be able to approximate the sampling distribution with a normal model, it is needed that $np \geq 10$ and $n(1-p) \geq 10$ , and both conditions are satisfied in this problem.

What is .61 repeating as a fraction and how did you get the answer

vivado [14]

61/100, because if it is 0.(value) than it is value / 100 assuming value is 2 digits long. We cannot simplify it further because 61 is prime number.

Tripling the greater of two consecutive even integers given the same result as subtracting 10fromm the lesser even integer. What

Dmitry [639]

The integers are -8 and -6.

To find these, first assume that the first integer is x. Then, because it is an even integer, assume the next is x + 2. Now we can write an equation to solve.

Tripling the greater = subtracting 10 from the lesser

3(x + 2) = x - 10 ----> Distribute the 3

3x + 6 = x - 10 ----> Subtract x from both sides

2x + 6 = -10 ----> Subtract 6 from both sides

2x = -16 ----> Divide both sides by 2

x = -8

Which is the first integer. We then can determine that the second one, which is two higher than the first, would be -6.
