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
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

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.

How is an exponential growth function of the form f(x)=a(1+r)^x related to an exponential function of the form f(x)=a*b^x?
A.
The value of a is the growth factor, and b is equal to the initial amount r.
B.
The value of a is the growth factor, and b is equal to the initial amount (1+r).
C.
The value of a is the initial amount, and b is equal to the growth factor (1+r).
D.
The value of a is the initial amount, and b is equal to the growth factor r.
The true statement is (c) the value of a is the initial amount, and b is equal to the growth factor (1+r).
How to compare the functions?The functions are given as:
f(x) = a(1 + r)^x
f(x) = a * b^x
An exponential growth function is represented as:
y = ab^x
Where
a represents the initial valueb represents the rateBy comparison:
b = 1 + r
Hence, the true statement is (c) the value of a is the initial amount, and b is equal to the growth factor (1+r).

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!

Answer:
B
Step-by-step explanation:
Its B because you distribute each term inside the parenthesis by the number out side
4×2x= 8x
4×3= 12
Get rid of the parenthesis after distributing
which makes 8x+12
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.
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

3,000 pounds of sand is usede to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes. how much sand can be put in each of the smaller sandboxes?
The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.
What is division?Division is breaking a number up into an equal number of parts.
Given that, 3,000 pounds of sand is used to fill sandboxes. 1,000 pounds can fill the big sandbox, and the rest can fill 4 equal-sized smaller sandboxes.
Amount left after filling the larger box = 3000-1000 = 2000 pounds
To find the equal amount of sand to be filled in 4 smaller boxes, we will divide the amount left to the number of boxes.
= 2000/4
= 500
Hence, The amount of sand that can be put in each of the smaller sandboxes is 500 pounds.

acute scalene
obtuse isosceles
obtuse scalene
acute isosceles
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.
