2(2x+2)

Distribute the first 2 to each term inside the parentheses

2 * 2x + 2 *2

4x+4

Answer:4x+4

Step-by-step explanation:

Multiply the numbers in the parentheses by 2

2 times 2x=2x+2x=4x

2 times 2=4

So....4x+4 is the answer

Answer:

$192

Step-by-step explanation:

Bill: $160.00

Tip: 20%

To figure out 10%, you need to move the decimal point over to the left one place: $16.00

10%: $16.00

16 times 2= $32.00

160.00+32.00= $192.00

Eight bricks are laid end to end along the edge of a flower bed.

Each brick is 11/2 inches long. How long is the row of bricks, in inches?

11/2 inches

A average row of bricks is 7-1/2 inches

11/2  x 7-1/2 = 38

38 inches

Answer:

1.5 times 8 equals 12. The row of bricks is 12 inches long

A function assigns the value of each element of one set to the other specific element of another set. The interval for which the given function is increasing is (-2,0).

A function assigns the value of each element of one set to the other specific element of another set.

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.

The given function is increasing only when the slope of the function is positive and when the value of x is increased from -2 to 0. Therefore, it can be concluded that the interval for which the given function is increasing is (-2,0).

Answer:

$7700

Step-by-step explanation:

As the account earns 6% interest, if we find 6% of $5000 we get $300, the interest is simple and given every month, meaning you get $2700 in interest as $300 x 9 months = $2700

$5000 initial + $2700 interest = $7700

EDIT:

It could be that the interest is 6% yearly, which means that yearly you get 6% interest, and the answer is $5225.

6% interest is $300 per year

$300÷12= $25 per month

$25 x 9 months = $225

$5000 initial plus $225 interest = $5225 total

Answer:

0.2587 = 25.87% probability that the first pass he completes is the second pass.

Step-by-step explanation:

Probability that the first pass he completes is the second pass.

Misses the first, with a 100 - 67.9 = 38.1% = 0.381 probability.

Completes the second, with 0.679 probability. So

0.381*0.679 = 0.2587

0.2587 = 25.87% probability that the first pass he completes is the second pass.

Answer:

a) 0.7734

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 101, \sigma = 24[/tex]

(a) what proportion of children aged 13 to 15 years old have scores on this test above 83 ?

This is 1 subtracted by the pvalue of Z when X = 83. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{83 - 101}{24}[/tex]

[tex]Z = -0.75[/tex]

[tex]Z = -0.75[/tex] has a pvalue of 0.2266

1 - 0.2266 = 0.7734

The answer is 0.7734

Step-by-step explanation:

When multiplying and deviding, you are raising them or lowering them by a certain degree, but adding or subtractions is just combining two fractions.

Just to quickly explain the "combining" aspect, during subraction, you are combining a positive with a negative.

Step-by-step explanation:

Amplitude of the sine function is 1.

So if its multiplied by -3, its amplitude is 3 (its always positive).

The midline of sin x is 0.

The midline of sin 2x is also 0.

The midline of -3*sin 2x is also 0.

So if you subtract this function by 5, then the new midline is -5.

Answer:

4448.23

Step-by-step explanation:

[tex]AV=PV(1+\frac{i}{n})^{nt}\\\\6000=PV(1+\frac{.06}{12})^{5*12}\\\\6000=PV*1.3488\\\\PV= 4448.23[/tex]

The present value of an investment that will be worth $6000 at the end of five years is, $4448.23

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Annual value = $6,000

Time = 5 years

Rate = 6%

Hence, We get;

A = P (1 + r/n)ⁿˣ

Substitute all the values, we get;

⇒ 6000 = P (1 + 0.6/12)⁶⁰

⇒ 6000 = P × 1.3488

⇒ P = $4448.23

Thus, The present value of an investment that will be worth $6000 at the end of five years is, $4448.23
