She obtains a list of 879 homeowners in her state, selects 300 of them at random, and emails a questionnaire to them. 64 questionnaires are returned. Of these, 80% stated that they believe that the current home warranty coverage needs to be completely overhauled. Classify the following groups as the population or the sample for this particular study.

Answer:

Step-by-step explanation:

The value of x + y for the given system of equations is found to be as 5.

A system of linear equations is a group of  equations having same number of variables and degree.

For the n number of variables n number of equations are required.

On the basis of number of solutions a system of equations can be classified as consistent and inconsistent.

The given equations are as follows,

x + 7y = 23                      (1)

3x + 14y = 48                  (2)

Solve the equations by substituting the value of x from equation (1) into (2) as follows,

3x + 14y = 48

=> 3(23 - 7y) + 14y = 48

=> -21y + 14y = 48 - 69

=> -7y = -21

=> y = 3

Then, x = 23 - 7y = 23 - 7 × 3 = 2

Thus, the value of x + y is given as 3 + 2 = 5.

Hence, the value of the required expression is given as 5.

Answer:

182.5 days

Step-by-step explanation:

So it looks like all you have to do is find 25% of 730 days. So, what you do is do 730 x 0.25 and you would get the answer of 182.5 days. If you have to round to the nearest whole number, it would be 183 days.

Answer: 105m²

Formula for Area of Circle: A = π r²

so, A = 3.14 (6)² (I got 6 because radius is half the diameter)

Don't forget to divide the final area of the circle in half, because It's only a semicircle.

Formula for Triangle: A = [tex]\frac{bh}{2\\}[/tex]

so, A = [tex]\frac{6(8)}{2}[/tex] (again, the "6" is just the diameter divided in half which forms the base of ONE triangle.)

You need to multiply the final area of the triangle by 2 since there are 2 triangles.

Answer:

[tex]zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )[/tex]

Step-by-step explanation:

Given

[tex]z =38 (cos(\frac{\pi}{8})+ i sin(\frac{\pi}{8})[/tex] and

[tex]w = 2 (cos(\frac{\pi}{16} ) + i sin(\frac{\pi}{16})[/tex]

Required

Determine zw

Given that:

[tex]x = v_1(cos(a) + isin(a))[/tex] and [tex]y = v_2(cos(b) + isin(b))[/tex]

[tex]x * y = (v_1 * v_2)*((cos(a+b) + isin(a+b))[/tex]

So, we have:

[tex]zw=(38 * 2) * (cos(\frac{\pi}{8} + \frac{\pi}{16}) + isin(\frac{\pi}{8} + \frac{\pi}{16}))[/tex]

[tex]zw=76 * (cos(\frac{2\pi + \pi}{16})+isin(\frac{2\pi + \pi}{16}))[/tex]

[tex]zw=76 * (cos(\frac{3\pi}{16}) +isin(\frac{3\pi}{16}) )[/tex]

The value of ZW is  [tex]\begin{aligned} (76) [Cos(\frac{3\pi}{16})+ \i\ Sin(\frac{3\pi}{16})]\end{aligned}[/tex].

Given to us,

[tex]\begin{aligned} Z &= 38 [cos(\frac{\pi}{8}) + i\ sin(\frac{\pi}{8}) ]\end{aligned}[/tex],

[tex]\begin{aligned}W &= 2 [cos(\frac{\pi}{16}) + i\ sin(\frac{\pi}{16}) ]\end{aligned}[/tex],

We know that,

[tex]{x = v_1 [ cos\ (a) +i\ sin\ (a)]}[/tex]  and  [tex]{y = v_2 [ cos(b) +i\ sin(b)]}[/tex]

So,

[tex]xy = (v_1 \times v_2) [ cos(a+b) + i\ sin(a+b)][/tex]

Therefore, we can write it as,

[tex]\begin{aligned}ZW &= [38cos(\frac{\pi}{8}) + 38\ i\ sin(\frac{\pi}{8}) ]\times [2cos(\frac{\pi}{16}) + 2\ i\ sin(\frac{\pi}{16}) ]\\&= (38 \times 2) \{Cos[\frac{\pi}{8} + \frac{\pi}{16}]\}+ \{i\ Sin[\frac{\pi}{8} + \frac{\pi}{16}]\} \end{aligned}[/tex]

        [tex]\begin{aligned}&= (76) [Cos(\frac{3\pi}{16})+ \i\ Sin(\frac{3\pi}{16})]\end{aligned}[/tex]

Hence, the value of ZW is  [tex]\begin{aligned} (76) [Cos(\frac{3\pi}{16})+ \i\ Sin(\frac{3\pi}{16})]\end{aligned}[/tex].

Step-by-step explanation:

Answer: The answer is C

Step-by-step explanation:  Graph C passes the horizontal line test and becomes a function as the horizontal line does not cut the curve more than once along any line drawn.

Also, the curve passes the vertical line test as well, if a vertical is drawn, it does not cut the curve more than once if drawn any where vertically.

Thus, graph C passes both the horizontal and vertical line test. So the curve has both function and inverse function.

Answer:

x=2

Step-by-step explanation:

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

The value of x in the equation is 2.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

2.5(6x - 4) = 10 + 4(1.5 +0.5x)

Now,

To solve for x, we need to simplify the equation and isolate x on one side. Here are the steps:

Distribute 2.5 and 4 on the left and right sides respectively:

15x−10=10+6+2x

Combine like terms on both sides:

15x−10=16+2x

Subtract 2x from both sides:

13x−10=16

Add 10 to both sides:

13x=26

Divide both sides by 13:

x=1326​

Simplify the fraction:

x=2

Therefore, by the equation the answer will be 2.
