What is the prime factorization of 18?

Answers

Answer:

2 x 3 x 3

Step-by-step explanation:

Prime Factorization is finding which prime numbers multiply together to make the original number.

Prime numbers are whole numbers greater than 1 that cannot be made by multiplying other whole numbers: 2, 3, 5, 7, 11, 13, 17, 19 ... etc.

Factors are the numbers you multiply together to get another number.

To find the prime factors of 18:

Start with dividing the number by the first prime number, 2.

So can 18 be divided by 2? Yes: 18 ÷ 2 = 9 ⇒ So 2 is a factor.

However, 9 is not prime number. Can 9 be divided by 2 and give us a whole number? No, as 9 ÷ 2 = 4.5 and 4.5 is not a whole number.

So let's try dividing 9 by the next prime number, 3: 9 ÷ 3 = 3.

We can now stop as we divided by the prime number 3 AND the result is a prime number.

Therefore, the prime factorization of 18 = 2 x 3 x 3

As two of the factors are the same (3) , we can also write this using exponents: 18 = 2 x 3²

Subtract the equations.
5x + 4y = 25

2(x+11) = -26 show all work pls

Answers

Answer:

x = -24

Step-by-step explanation:

First, distribute 2 to all terms within the parenthesis:

2(x + 11) =

2 * x = 2x

2 * 11 = 22

2x + 22 = -26

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

First, subtract 22 from both sides of the equation:

2x + 22 (-22) = -26 (-22)

2x = -26 - 22

2x = -48

Next, divide 2 from both sides of the equation:

(2x)/2 = (-48)/2

x = -48/2

x = -24

x = -24 is your answer.

Kardal did a study to determine the correlation between men’s heights, x, and their shoe sizes, y, and found the following data:

(60, 8.5), (65, 10), (66, 12), (68, 11.5), (63, 9.5), (72, 12.5), (62, 8.5), (69, 12.5), (70, 11.5)

Kardal used the line of best fit to predict that a man 80 inches tall would wear about a size 16 shoe. What can be concluded about this prediction? Check all that apply.

The prediction is reasonable.
The prediction is an interpolation.
No data is given in the scatterplot for a height of 80 inches, but a shoe size can still be predicted.
A prediction cannot be made for a man who is 80 inches tall.
A man who is 80 inches tall will likely wear a size 12.5 shoe.

Answer:

first and third option:)

Step-by-step explanation:

Kardinal did a study to determine the correlation between men’s heights, x, and their shoe sizes y, the conclusion about this prediction is mathematically given as The prediction is reasonable, and No data is given in the scatterplot for a height of 80 inches, but a shoe size can still be predicted. Option A ,C.

What can be concluded about this prediction?

Generally, the equation for the equation of the line is mathematically given as

y=0.377x-14.214

Where the value of R^2 =0.7784 and x=80

y=0.377x-14.214

Hence

y=0.377(80)-14.214

y=16

In conclusion, Although no data is provided in the scatterplot for a height of 80 inches, a shoe size may still be estimated.

A 5 person sports team has an average 40 yard dash time of 5. 7 seconds. When a 6th player is added to the team, the new mean is 5. 5 seconds. What is the new players personal time for the 40 yard dash?.

Answers

The new player's personal time is 4.5 seconds.

What is the new player's personal time?

The first step is to determine the total time the 5 persons complete the dash.

Total time = 5 x 5.7 = 28.5 seconds

The second step is to determine the total time for the 6 people to complete the dash.

Total time = 6 x 5.5 = 33 seconds

The third step is to find the difference of the time in the previous two steps: 33 - 28.5 = 4.5 seconds

A ball is dropped from a height of 500 m the table shows the height of each bounce write a rule to represent the height of the ball after each bounce how high does the ball bounce of the 6th bounce

Answers

The rule that represents the height of the ball after each bounce is;

H(n) = 400(0.8)^(n - 1)

Geometric Sequence Progression

From online sources, we have that;

After first bounce, height = 400 m

After 2nd bounce, height = 320 m

After 3rd bounce, height = 256 m

Formula for the nth term of a geometric sequence is;

T_n = ar^(n - 1)

First term is 400m

Since second term is 320, then common ratio is;

r = 320/400

r = 0.8

Thus, the 6th bounce which is the 6th term will be;

T_6 = 400 * 0.8^(6 - 1)

T_6 = 131 m
