I am a number between 60 and 100. My ones digit is two less than my tens digit. I am a prime number. What number am I. Explain.

Answers

Answer 1

Answer: Let's name the digit:

x- ones digit
y - tens digit

we know that x=y-2.

Now, y can be 6,7,8,9 (the number is between 60 and 100 (so depending on your understanding of "between", 0 is also possible. but then the number would have to have -2 as its ones digit, so in any case, it's not possible).

So the possibilities with x=y-2:

64
75
86
97
Out of those 64 and 86 are even, so they can't be prime.
75 has 5 in its ones number: it's divisible by 5.

so the correct answer is 97.

Answer 2

Answer: Find the number in where it is between 60 and 100.
Its ones digit is 2 less than its tens digits. And it is a prime number.
=> thus the digit is 2 digit since it has ones and tens place value.
Let’s assign a variable to use. Let a be the value of ones and b the value of tens
ones = A – 2
tens = y
So let’s find the number between 60 to 100 that the value of ones is 2 less than the value of tens
=> 64
=> 75
=> 86
=> 97
Now, we have possible answers. However, prime numbers are not divisible and is not even numbers.
So the answer is 97.

P(x) = 2x^2 + 74x + 644B. P(x) = 2x^2 + 28x - 414C. P(x) = 2x^2 + 102x + 1,288D. P(x) = 2x^2 + 110x + 1,472

-6(a+8) how do I simplify ?

Answers

Answer:

-6a-48

Step-by-step explanation:

distribute

Use the Distributive Property:

You "distribute" -6 into the equation by multiplying it by each number in the parentheses.

-6(a+8)
1) multiply -6 by a, which equals -6a
2) multiply -6 by 8, which equals -48

Your equation should be -6a-48

From there, it can be seen that you can divide -6 from each number in the equation.
-6a/-6 just leaves you with a
-48/-6 gives you 8

a-8

What is the MAD of 15, 17, 15, 17, 21, 17, 15, 21, 20, and 18

Answers

Okay i will just do this step by step...

1st.) Find the mean of all the values.
Of course finding the mean is adding all the numbers up together and dividing by the number of numbers present.
So add all the numbers...
15 + 17 + 15 + 17 + 21 + 17 + 15 + 21 + 20 + 18 = 176
Now divide by 10 since there are ten numbers.
176 ÷ 10 = 17.6

2nd.) subtract the mean from each value, (ignore the minus signs in our answer, they are not needed, our answer will be a positive number!!!)
So...
15 - 17.6 = 2.6
17 - 17.6 = 0.6
15 - 17.6 = 2.6
17 - 17.6 = 0.6
21 - 17.6 = 3.4
17 - 17.6 = 0.6
15 - 17.6 = 2.6
21 - 17.6 = 3.4
20 - 17.6 = 2.4
18 - 17.6 = 0.4

Now our new Set of numbers is...
2.6, 0.6, 2.6, 0.6, 3.4, 0.6, 2.6, 3.4, 2.4, 0.4

3rd.) So now we have to take those numbers and find the Mean out of those... Soo first add them up together.
2.6 + 0.6 + 2.6 + 0.6 + 3.4 + 0.6 + 2.6 + 3.4 + 2.4 + 0.4 = 19.2
Now divide by the number of numbers present or in this case (10)
soooo
19.2 ÷ 10 = 1.92

sooooo
MAD = 1.92

If you answered 37 problems correctly on a 42 question test, what percent would you recieve

Answers

The fraction would be 37 out of 42. You basically divide the two and get something around 88%.

Final answer:

On a test with 42 questions, answering 37 correctly yields a score of approximately 88 percent. This result is obtained by dividing the number of correctly answered questions by the total number of questions, and then multiplying that result by 100 to find the percent.

Explanation:

The subject for this problem is percentages, a common topic in mathematics. To solve this, you need to relate the number of correct answers to the total number of questions. The formula for percent is (part / total) * 100, where the part is the number of problems you answered correctly (37), and total is the overall number of questions on the test (42).

In this case, you'd calculate (37 / 42) * 100, which equals approximately 88.09%. Therefore, if you answered correctly on 37 out of 42 questions, your score would be about 88 percent.
