11. Number Sense Jamal saysthat the sum

of 183 + 198 is less than 300. Is

Jamal's

answer reasonable? Why or

why not

Both addends are

des to 200.

Answers

Answer 1
Answer:

Answer:

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?​

Answers

Answer:

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?

Answers

Answer:

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%.

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:

Answers

Answer:

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}

Explain why sketching y=sin(x) can help graph y=csc(x)

Answers

The graph of csc x is a parabola with its vertex at the node of the graph of sin x.
y = csc (x) = 1/sin (x)

When you realize that sin (x) is an even function, you can conclude that csc(x) is also even.

Whenyou draw y = sin(x), you will see the zeroes of the function, which are values for which the funcion csc(x) is not defined, but goes to + or - infinity, i.e. you obtain the asymptotes.

You can also realize that the maximums of sin(x) will result in minimums of csc(x).
