His overall net profit would be $500 dollars because every two weeks he makes $500 so over 4 weeks he would make $1000, but lose $500 to rent.

Answer:

$500 net profit in 4 weeks

Step-by-step explanation:

+$50 a day, 5 days a week, -$500 every 4 weeks

1. solve for initial profit in 4 weeks

5 profitable day*4 weeks= 20 days Tom makes a profit

20 days*$50= $1000 in 20 days

2. subtract rent from initial profit

1000-500= $500

A box contains 3 coins. One coin has 2 heads and the other two are fair. A coin is chosen at random from the box and flipped. If

Blababa [14]

Answer: Our required probability is $\dfrac{1}{2}$

Step-by-step explanation:

Since we have given that

Number of coins = 3

Number of coin has 2 heads = 1

Number of fair coins = 2

Probability of getting one of the coin among 3 = $\dfrac{1}{3}$

So, Probability of getting head from fair coin = $\dfrac{1}{2}$

Probability of getting head from baised coin = 1

Using "Bayes theorem" we will find the probability that it is the two headed coin is given by

$\dfrac{\dfrac{1}{3}\times 1}{\dfrac{1}{3}\times \dfrac{1}{2}+\dfrac{1}{3}\times \dfrac{1}{2}+\dfrac{1}{3}\times 1}\\\\=\dfrac{\dfrac{1}{3}}{\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{3}}\\\\=\dfrac{\dfrac{1}{3}}{\dfrac{2}{3}}\\\\=\dfrac{1}{2}$

Hence, our required probability is $\dfrac{1}{2}$

No, the answer is not $\dfrac{1}{3}$

Write an equation for this situation.

kirza4 [7]

Answer: A) y = 3x + 2

Step-by-Step Explanation:

Let ‘x’ be the number of months
Let ‘y’ be the total no. of books he read

Given:

He read 2 books before joining (+2)
He plans to read 3 books per month (3x)

Equation:

= Total no. of books = 3 multiplied by the no. of months + 2 books he had read

The sum of two numbers is 8, and their product is 15. What is the largest number?

AfilCa [17]

Hello there!

The sum of two numbers (x + y) is 8 (=8).
Their product (x * y) is 15 (=15).
x + y = 8
x * y = 15

First, we know that the two number must be positive and under 8, as the product is positive.

Let's list out some numbers that are from 1 to 8 that sum up to 8;
1 + 7
2 + 6
3 + 5
4 + 4

Now, we need to multiply the two numbers that add up to 8, and see which makes a product of 15.
1 * 7 = 7, this does not work.
2 * 6 = 12, this does not work.
3 * 5 = 15, this works!
4 * 4 = 16, this does not work.

Since we are looking for the larger number in our pairs, let's pick the largest one out of the correct pair, which is 5.

The largest number is 5.

I hope this helps!
