A company manufactures skateboards. Each skateboard requires 1 6/7 hours of labor to assemble and 2 1/2 hours of labor to finish

Assoli18 [71]

Answer: The total cost will be $156.85.

Step-by-step explanation:

Since we have given that

Time taken by labor to assemble the each skateboard is given by

$1\frac{6}{7}\ hours\\\\=\frac{13}{7}\ hours$

Time taken by labor to finish and stain each skateboard is given by

$2\frac{1}{2}\ hours\\\\=\frac{5}{2}\ hours$

Cost of labour to the company per hour = $36.00

According to question,

We will use "Distributive Property":

$a\times (b+c)=a\times b+a\times c$

$36(\frac{13}{7}+\frac{5}{2})\\\\=36\times \frac{13}{7}+36\times \frac{5}{2}\\\\=\frac{468}{7}+18\times 5\\\\=\frac{468}{7}+90\\\\=\frac{468+630}{7}\\\\=\frac{1098}{7}\\\\=\$156.85$

Hence, the total cost will be $156.85.

For a certain data set the regression equation is y = 2 + 3x. The correlation coefficient between y and x in this data set _____

lozanna [386]

Answer:

C. Must be 1

Step-by-step explanation:

The correlation coefficient of an equation represents the relation between the two variable ( dependent and independent )

It lies between -1 to 1,

If an equation has strongly positive correlation then the value of correlation coefficient is 1,

If there is no relation then the value of correlation is 0,

If there is strongly negative relation then the value of correlation coefficient is -1,

Here, the equation is,

y = 2 + 3x

Since, the value of y is increasing with increasing the value of x,

We can say that there is strong positive relation between the variables x and y,

Hence, by the above statements,

The correlation coefficient between y and x in this data set must be 1.

Option 'C' is correct.

It has been estimated that the population of Indianapolis is growing at a rate of 0.9% per year. Assuming that population growth

Mumz [18]

Answer:

2,136,605

Step-by-step explanation:

To estimate growth, we use the formula shown below:

$F=P(1+r)^t$

Where

F is the future amount (we want to find for Jan 2024)

P is the present amount (present population of 1,988,817)

r is the rate of growth (0.9% means 0.009)

t is the time in years (from Jan 2016 to Jan 2024 is 8 years, t = 8)

Let's put these into the formula and figure out F:

$F=P(1+r)^t\\F=1,988,817(1+0.009)^8\\F=2,136,604.5$

Rounding we get the population in Jan 2024 to be 2,136,605

PLS HELP ASAP PLSSSS!!!!!!!!!!!!!!!!!!!!!!!!!

Lunna [17]

Answer:

2800 in^3

Step-by-step explanation:

Calculate the volume as normal, but take 1/10 of the result. Since volume is length*width*height, we have 50*28*20 which is 28000. 1/10 of that is 2800. So the volume when scaled down by a factor of 1/10 is 2800 in^3
