Answer:  Choice A. 3/7

===============================================

Explanation:

We have a 5 by 3 grid of letters. There are 5*3 = 15 letters total.

Of that total, there are 5 vowels (2 'e's in row 1, 2 'e's in row 2, and 1 'e' in row 3)

So there are 15-5 = 10 consonants.

The probability of pulling out a consonant is 10/15 = 2/3

After selecting that consonant, we have 10-1 = 9 consonants left out of 15-1 = 14 letters total.

The probability of selecting a second consonant, after not replacing the first selection, is 9/14.

Multiply the two fractions found:

(2/3)*(9/14) = (2*9)/(3*14) = 18/42 = 3/7

To reduce 18/42, we divide both parts by the GCF 6, which is how we end up with 3/7.

5/14 or 35% I think

What is the probability of rolling a number less than 6 on a number cube labeled 1 through 6?
A. Likely
B. unlikely
C. as likely as not
D. impossible
F. certain

Answers

Answer:

A. likely

Step-by-step explanation:

There are 6 outcomes 1, 2, 3, 4, 5 and 6.

Numbers less than 6 are 1, 2, 3, 4 and 5.

So the chance to roll a number less than 6 is 5/6, which has a probability of likely as there are more chances to roll a number less than 6

Heres how I did it. I used my fingers for this, it's a little odd I know but it works. I put up one finger for each half. So each finger represents one half. I needed to get to 2 1/2 so I put up two finger and I said "that's one " because a half plus a half is a whole or just one. Then I put up one more finger and I said " That's one and a half". I then put up two more and then I had 2 1/5. What I did then was count how many fingers I had up. I had 5 fingers up. So then I multiplied 3 x 5 and that gave me 15. Hope I could help!

acute isosceles

Answers

Answer:

Obtuse scalene

Step-by-step explanation:

Answer:

obtuse scalene

Step-by-step explanation:

Scalene means that none of the sides are equal.

Isosceles means that two of the sides are equal.

Obtuse means an angle in the triangle is larger than 90 degrees.

Acute means all angles in the triangle are smaller than 90 degrees.

None of the sides are equal so this triangle has to be scalene and the angle in the bottom right is larger than 90 degrees so this triangle is obtuse.

Answer:

Step-by-step explanation:

Its B because you distribute each term inside the parenthesis by the number out side

Get rid of the parenthesis after distributing

Answer:

B. 8x + 12

Step-by-step explanation:

First you'd start with the parentheses because of PEDMAS. But because you can't do anything in there, you go to multiplying 4 by each item inside the parentheses. 4x2x gives 8x. 4x3 gives 12. Leaving you with 8x+12. Hope that helps! :)

Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement.

Answers

Answer: 38 and 40 are both even numbers.

even numbers cannot be prime numbers; as they have their own factors.

prime numbers only have two factors: the number 1 and the number itself.

example: 17 is a prime number. the only factors it has is 1 and 17.

38 and 40 are both divisible by 2, so they have more than two factors:

38 = 1 * 38,  2 * 19

40 = 1 * 40, 2 * 20, 4 * 10, 4 * 5

therefore, they are not relatively prime, or prime at all; they are even numbers.

Answer:

they are not because 40 has more that 1 factor it has more than 2 which makes it composite  38 on the other hand is relatively prime it only has 2 factors
