The correct answer is B


These students do not represent the whole population of students, so the results of the survey will disproportionately recognize the opinion of the extracurricular students.

If the side lengths of a cube are 14 feet, what is the correct way to write the expression to represent the volume of the cube i
Kryger [21]

Answer: Choice A) 14^3

This is the same as writing 14^3

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

Explanation:

Since all the sides are 14 feet long, we can basically say length = width = height = 14.

Or put another way:

  • length = 14
  • width = 14
  • height = 14

The volume of the cube is length*width*height = 14*14*14 = 14^3 = 2744 cubic feet.

-----------

The term 14^3 has a base of 14 and exponent of 3.

The base is what we multiply out while the exponent tells us how many copies of the base to multiply. In this problem, we have 3 copies of 14 being multiplied. So that's why 14^3 = 14*14*14

If you were to say something like 3^14, then you would have 14 copies of 3 multiplied out, which is a much larger value. So we'll cross choice B off the list.

Choice C isn't correct either since again we're using exponents and not multiplication to tie together the 14 and 3.

Choice D would be correct if your teacher wanted it in expanded form, instead of exponent form.

Rufina [12.5K]

(Hard) A composite number n is called a Carmichael number bn−1 ≡ 1 (mod n) for every number b such ... Base case: When n = 2 the formula a + c ≡ b + d (mod m) was already given. ... The sequence goes 1, 3, 7, 15, 31,... guess that it is equal to 2n+1 − 1. ... Prove (now using induction on n) that fm|fmn for all n ≥ 1.

bongo had a balance of $345.28 in his checking account. During the week amounts: $65.08, $24.50, and $118.95. He then made a dep
vichka [17]

Answer: 192.75

Step-by-step explanation:

I am answering your question assuming that the three amounts were checks that were written out during the week.

Beginning balance = 345.28

Subtract the total amount of the checks (65.08 + 24.50 + 118.95 = 208.53)

345.28 - 208.53 = 136.75

Next, add the amount of the deposit. 136.75 + 56.00 = 192.75
