# 11. Number Sense Jamal saysthat the sumof 183 + 198 is less than 300. IsJamal'sanswer reasonable? Why orwhy notBoth addends aredes to 200.

Jamal's answer isn't reasonable because the sum of 183 and 198 is 381, which is way more than 300 and nowhere less than 300.

Step-by-step explanation:

Jamal makes an assertion that the sum of 183 and 198 is less than 300.

We are to check if Jamal's answer is reasonable or not.

183 + 198 = 381 > 300

The sum of the two numbers, 381, is evidently not less than 300, hence, Jamal's answer isn't reasonable because it is downright wrong.

Hope this Helps!!!

Set up a proportion and solve each problem. Round each answer to the nearest tenths. 5) What is 35% of 74? 6) 78 is what percent of 95? 7) Find what% of 54 is 6. 8) 28 is 60% of what number?​

5)  35 / 100 = X / 74      X = 2590 / 100 = 25.9

or .35 * 74 = 25.9

6) 78 / 95 = X * 100

X = 7800 / 95 = 82.1 %

or X = 78/95 * 100 = 82.1 %

7)  60/100 * X = 28

X = 2800 / 60 = 46.7

Or .6 * X = 28

X = .28 / .6 = 46.7

Mr. Johnson borrowed $8000 for 4 years to make home improvements. Ifhe repaid a total of$10, 320, at what interest rate did he borrow the money?

Mr. Johnson borrowed the money at an interest rate of 4.25%.

Step-by-step explanation:

We can use the formula for simple interest to solve this problem:

Simple Interest = Principal x Rate x Time

Where:

Principal is the amount borrowed.

Rate is the interest rate (as a decimal).

Time is the length of time the money is borrowed for.

We know that Mr. Johnson borrowed $8000 for 4 years and repaid a total of$10,320. We can use this information to set up an equation:

10,320 = 8000 + 8000 x Rate x 4

Simplifying this equation:

10,320 = 8000 + 32000 x Rate

Dividing both sides by 32000:

Rate = (10,320 - 8000) / (8000 x 4) = 0.0425 or 4.25%

Therefore, Mr. Johnson borrowed the money at an interest rate of 4.25%.

Two number cubes are rolled for two seperate events: Event A is the event that the sum of numbers on both cubes is less than 10. Event B is the event that the sum of numbers on both cubes is a multiple of 3. Complete the conditional-probability formula for event B givem thaf event A occurs first by writing A and B in the blanks:

Probability of getting sum less than

10 =  \frac{30}{36}=  \frac{5}{6}

Probability of getting a multiple of 3= \frac{20}{36}= \frac{5}{9}

(A) P(B|A)= \frac{P(B∩A)}{P(A)} = \frac{15/36}{30/36}= \frac{15}{30}=0.5

(B)P(A|B)= \frac{P(A∩B)}{P(B)}= \frac{15/36}{5/9}=0.75

(C) {A∩B} = {3, 6, 9, 12, 15, 18}

(D) {A} = {1, 2, 3, 4, 5 ,6, 7, 8, 9}
