A regression analysis was performed to determine the relationship between the costs of a product (y), the time to make the product (x1 ), the number of different materials used (x2), and the amount spent on marketing the product (x3). The estimated regression equation is ŷ = 83- 2x1+ 6x2 + 1.1x3.

What is the estimated cost if the time to make the product is 5 hours, the number of different materials used is 4, and the amount spent on marketing is $100?

a. 83
b. 213
c. 185.4
d. 205.

Answer:

A. 11 m

Step-by-step explanation:

Given that

the ten workers are fencing  25 m by 28 m

And, they finished the fencing 95 m

We need to find out the number of more meter of fence that could be developed

So,

= (25+25) + (28+28)

= 106 - 95

= 11

Hence, 11 more meters should be build

Therefore the correct option is A.

Answer:

[tex]f(x)=-9(2)^(^x^-^1^)[/tex]

Explanation:

First, we find the common ratio by dividing any term by its previous term. We should do this a couple of times to make sure it's consistent. In this case, our common ratio is 2. Our first (or 1th) term of the sequence is -9, so our formula becomes

[tex]f(x)=-9(2)^(^x^-^1^)[/tex].

Answer:

0.4032

Step-by-step explanation:

1. We assume, that the number 72 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 72 is 100%, so we can write it down as 72=100%.

4. We know, that x is 0.56% of the output value, so we can write it down as x=0.56%.

5. Now we have two simple equations:

1) 72=100%

2) x=0.56%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

72/x=100%/0.56%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

i did the test :)

Note that the number of eggs the above-described trader bought is 180 eggs. This is solved using simple arithmetic.

Let no. of the eggs be x, then

Money the trader paid for eggs = 64/12x = 16/3x

The money the trader got from

Seling two third eggs =2/3x*240/30

=16/3x

Money get from one third= x/3*225/30

=5/2

Profit= [16/3x+5/2x] - 16/3x

5/2x = 450

x =450*2/5

=180

Therefore, the number of eggs that the trader bought is 180.

Answer:

48 years

Step-by-step explanation:

Let the ratio of their ages be

4:2:1

Sum up the numbers

4+2+1

= 7

Their total ages is 84

7/84

= 1/12

Therefore Jim age can be calculated as follows

= 12×4

= 48

Hence Jim is 48 years

Calculate the missing values.

Jill Kingman pays a $419.00 premium annually. This represents 35% of the total premium. The rest of the premium is paid by her employer.

Use a thousands comma where applicable.

1. 100 (100% of cost)  - 35 = 65% company percent

2. 419.00 ÷ .35 (or, 35%, but use the decimal) = 1197 total premium

3. 0.65 × 1197 = 778.05 company payment

Answer:

Step-by-step explanation:

Assuming you're solving for p:

[tex]m=2^{-1} *2^p(2^p-1)[/tex]

Let [tex]y=2^p[/tex]

Now we can re-write the equation with [tex]y[/tex] instead of [tex]2^p[/tex].

[tex]m=\frac{1}{2} y(y-1)[/tex]

[tex]2m=y^2-y[/tex]

[tex]y^2-y-2m=0[/tex]

Use the quadratic formula to get:

[tex]y = \frac{1+\sqrt{1+8m} }{2}[/tex]

or

[tex]y = \frac{1-\sqrt{1+8m} }{2}[/tex]

Therefore, using natural log and log rules:

[tex]2^p = \frac{1+\sqrt{1+8m} }{2}[/tex], [tex]ln(2^p)= ln(\frac{1+\sqrt{1+8m} }{2})[/tex],[tex]pln(2) = ln(\frac{1+\sqrt{1+8m} }{2})[/tex], [tex]p = \frac{ln(\frac{1+\sqrt{1+8m} }{2})}{ln(2)}[/tex]

or

[tex]2^p = \frac{1-\sqrt{1+8m} }{2}[/tex], [tex]ln(2^p)= ln(\frac{1-\sqrt{1+8m} }{2})[/tex], [tex]pln(2) = ln(\frac{1-\sqrt{1+8m} }{2})[/tex], [tex]p = \frac{ln(\frac{1-\sqrt{1+8m} }{2})}{ln(2)}[/tex]

Answer:

Interest earned = $32.835

Step-by-step explanation:

Given the following data;

Principal = $275

Number of times = 0.5

Interest rate = 2.9% = 0.029

Time = 4 years

To find the interest earned, we would use the compound interest formula;

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

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] A = 275(1 + \frac{0.029}{0.5})^{0.5*4}[/tex]

[tex] A = 275(1 + 0.058)^{2}[/tex]

[tex] A = 275(1.058)^{2}[/tex]

[tex] A = 275(1.1194)[/tex]

A = $307.835

Interest earned = 307.835 - 275

Interest earned = $32.835
