Chloe works for an estate agent.
Lunna [17]

Answer:

£24,980

Step-by-step explanation:

total pay = monthly salary + percent of annual profit + £250 bonus

monthly salary = £1,850

annual salary = 12 × £1,850 = £22,200

agency income = £356,000

agency costs = £280,000

annual profit = income - costs = £356,000 - £280,000 = £76,000

percent of annual profit = 3% × £76,000 = 0.03 × £76,000 = £2,280

£250 bonus = 2 × £250 = £500

total pay = monthly salary + percent of annual profit + £250 bonus

total pay = £22,200 + £2,280 + £500

total pay = £24,980

Reason abstractly. Are all horizontal lines parallel? Use slope<br> explain how you know.
ohaa [14]

Answer:

All horizontal lines are NOT parallel.

Step-by-step explanation:

We learned that lines go on forever.  

If one line is slightly slanted, and the other line is completely straight,  these lines are not parallel, as they will meet at some point.

Hope this helped :)

A state end-of-grade exam in American History is a multiple-choice test that has 50 questions with 4 answer choices for each que
Assoli18 [71]

Answer:

Q1) The student has a 0.01% probability of passing the test.

Q2) She has a 99.91% probability of passing in the test.

Step-by-step explanation:

For each question, there are only two possible outcomes. Either he gets it correct, or he gets it wrong. So we solve this problem using the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}

In which C_{n,x} is the number of different combinatios of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And \pi is the probability of X happening.

For this problem, we have that:

Question 1.

There are 50 questions, so n = 50.

The student is going to guess each question, so he has a \pi = \frac{1}{4} = 0.25 probability of getting it right.

He needs to get at least 25 question right.

So we need to find P(X \geq 25).

Using a binomial probability calculator, with n = 50 and \pi = 0.25 we get that P(X \geq 25) = 0.0001.

This means that the student has a 0.01% probability of passing the test.

Question 2.

Now, we need to find P(X \geq 25) with \pi = 0.70. So P(X \geq 25) = 0.9991

She has a 99.91% probability of passing in the test.
