Please help, I have no idea how to do this

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Answer:

I need the values of either X or Y to solve this. I can solve for what X is though.

Step-by-step explanation:

A: X = -12

B: X =78

C: X = 12.13

I hope this helps you, but since both X and Y are unknown variables, you can't solve it, only simplify (which it already is.)

Answer:

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Answer:

C: 8 feet

Step-by-step explanation:

You have to find the parameter.

To do that you add all the side lengths together.

15+15=30 now you have to subtract 30 from 46 to find how much room is left.

46-30=16 now divide your answer by 2 to get the 2 remaining sides of the deck.

if Martha is not earning money to pay it back, it would be negative. Each week, she loses -9.72 dollars. so -9.72 x 3 weeks = your problem. I'll let you take it from there and solve the rest

$1750 x 21 days = $36,750 for her daily article

9.72 x 3 weeks = $29.16

$36,750 - $29.16 = $36,720.84

balance = $36,720.84

Answer:(x,y)=(1,1)

Step-by-step explanation:     y=2x - 1 , 5x - 4y=1

                                                y=2x-1

5x-4y=1

5x-4(2x-1)=1

x=1

y=2x+1-1

y=1

(x,y)=(1,1)

1=2 x 1 - 1

5 x 1 - 4 x 1 = 1

1=1

1=1

therefore the anwser would be (x,y)=(1,1)

Answer:

(x,y)=(1,1)

Answer: The ratio is 18:3

Step-by-step explanation:

Answer:  6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Answer: The box's volume is 9065 in^3 (inches cubed).

Step-by-step explanation: To find the volume of a box (and any regular rectangular prism), you multiply the length, width, and height. In this case, you would do 20 x 18.5 x 24.5, which would give you the answer of 9065 in^3.

*Notes: I wrote the 1/2 as a decimal, tagging the .5 on at the end of the number, instead of as a fraction.

The unit at the end of the calculation is inches cubed (to the exponent 3) because the box occupies a three-dimensional space.
