Step-by-step explanation:

1 T shirt = 28.14

There are 2 methods this can be done.

Method `1

Adding 3 times

28.14 + 28.14 + 28.14 = $84.42

Method 2

Multiplying 28.14 by 3

28.14 times 3 = $84.42

Therefore answer is 84.42

Answer: Inequality Form: x ≥ 4

lll. 4

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Your answer is x ≥ 4

Step-by-step explanation:

a) Simplify both sides of the inequality.

9 ≤ 4x − 7

b) Flip the equation.

4x − 7 ≥ 9

c) Add 7 to both sides.

4x − 7 + 7 ≥ 9 + 7

4x ≥ 16

d) Divide both sides by 4.

4x/4 ≥ 14/4

x ≥ 4

A segment MN has endpoints M(-7.-6) and N(7,7). Find the coordinates of partition point P that divides the segment into a 5:2 ratio. ​

___________________________

Find the coordinates of partition point P that divides the segment into a 5:2 ratio. ​

5:2 means that it is divided into 7, and we do not move two positions from (7,7)

If you rent an apartment that cost $1000 per month during the first year, but the rent is set to go up 8% per year, the the rent amount  of the apartment during the 5th year of living in the apartment is $1469.32

The initial rent amount = $1000

The percent of rent increase each year = 8%

Time period = 5 years

Here we can use the compound interest equation

A = [tex]P(1+\frac{r}{100})^t[/tex]

Substitute the values in the equation

The rent amount  of the apartment during the 5th year of living in the apartment = [tex]1000(1+\frac{8}{100})^5[/tex]

= $1469.32

Hence, if you rent an apartment that cost $1000 per month during the first year, but the rent is set to go up 8% per year, the the rent amount  of the apartment during the 5th year of living in the apartment is $1469.32

The length of the red line segment on this number line is: C. 2 1/2.

A number line simply means a type of graph with a graduated straight line which comprises both positive and negative numbers that are placed at equal intervals along its length.

This ultimately implies that, a number line can be used to compare or determine the difference (distance) between two numbers plotted on it. Additionally, a number line primarily increases in numerical value towards the right and decreases in numerical value towards the left.

Note: Each interval on this number line represents 1/4 and the total intervals between the red dots is 10.

From the number line shown above, we have:

Distance = 10 ×  (1/4)

Distance = 10/4

Distance = 5/2

Distance = 2 1/2.

we have that

Option B

y=50

Option A

Find out the slope

take two points from the graph

(0,20) and (150,50)

m=(50-20)/(150-0)

m=30/150

m=1/5=$0.20 per mile

therefore

y=0.20x+20

Part A

For x=75 miles

Option A -----> y=0.20(75)+20=$35

Option B ------> y=$50

therefore

Option A costs less

Find out the difference

$50-$35=$15

Cost $15 less than the other option

Part B

Looking at the graph

For x=150 miles

Both options cost the same

If David drives more than this amount option B costs less

The reasonable fraction for the part of the pan of brownies Kayla gave away is 1/2.

Kayla gave 1/3 of a pan of brownies to Ella and 1/6 of the pan to Eli.

Therefore, the part given away will be the addition of the fractions. This will be:

= 1/3 + 1/6

= 2/6 + 1/6

= 3/6

= 1/2

Therefore, 1/2 of the brownies were given away.

In 95% confidence interval for the population proportion of successes

In 95% confidence interval for the population proportion of failures

exists CI = 0.375 +- 1.96 × sqrt(0.375 × 0.625/80).

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

You have a 5% probability of being incorrect with a 95% confidence interval. You have a 10% probability of being incorrect with a 90% confidence interval. A 95% confidence interval is narrower than a 99% confidence interval (for example, plus or minus 4.5 percent instead of 3.5 percent).

a) Sample proportion of successes (phat) = 50/80 = 0.625

z-critical for 95% CI is 1.96

The number of positive factors of 96  which are also multiples of 12 are 4 which are 12,24,48, and 96.

Positive factors of 96 = 1,2,3,4,6,8,12,16,24,32,48 and, 96

Multiples of 12 upto 96 = 12,24,36,48,60,72, 84 and 96

Common numbers between the two are 12,24,48 and 96.

Hence, there are only 4 positive factors of 96 which are also the multiples of 12

Factors

Factors are the numbers that can divide a number exactly. Hence, after division, there is no remainder left.

Multiples

A multiple is a result obtained by multiplying a number by an integer(it shouldn’t be a fraction). The multiples of the whole number are obtained by taking out the product of the counting numbers and that of whole numbers.

In the question ,

it is given that

discount on list price for the computer is 15%

sales tax = 8%

let the list price for the computer be $p  .

So, sales price is = p - 0.15*p = 0.85*p

tax on sale price is = 8% of 0.85*p = 0.08*0.85*p = 0.068*p

Total Price = sale price + tax on sale price

Substituting the values of tax and sale price ,

we get

The car stops after moving for 20 seconds

From the question, the function is given as

v(t) = 0.5t^2 - 14t + 80

When the car comes to a stop, the vehicle is 0

This is represented as

v(t) = 0

So, we have

0.5t^2 - 14t + 80 = 0

Expand the equation

0.5t^2 - 10t - 4t + 80 = 0

Factorize the equation

0.5t(t - 20) - 4(t - 20) = 0

So, we have

(0.5t - 4)(t - 20) = 0

Solve for t

t = 8 and t  = 20

20 is greater than 8

The equation of the line that is parallel to k and passes through (-1, 3) is

- x + 2y = 7

The equation of a line can be represented in different form such as point slope form, slope intercept form and standard form.

Therefore, the equation of the line is parallel to k.

Parallel line shave the same slope.

Therefore, let's find the slope of k to find the slope of the equation of the line.

Hence, using (7, 2)(1, -1)

m = -1  - 2 / 1 - 7

m = - 3 / -6

m = 1/ 2

Therefore, the slope of the line is 1 / 2. Let's find the y-intercept using the point (-1, 3)

3 = 1 / 2(-1) + b

3 = - 1 / 2 + b

b = 3 + 1 / 2

b = 7 / 2

Hence, the equation is as follows;
