Answer:

stratified random sampling

Step-by-step explanation:

The sampling design that is involved in the above study is the stratified random sampling design. In the study the population of sample is divided into two kinds of members. The two kinds of members are the local business members and the professional club members in a local area. These are called the stratums. The sociologist wishes to collect data or information from these two types of people.

Answer:

[tex]0<p\leq15.5[/tex]

Step-by-step explanation:

Amount of gasoline in the tank is 5.5 gallons

21 gallons is the capacity of the fuel tank in the car

A is the amount of gasoline in the fuel tank after purchase which will be less than or equal to 21 gallons.

So the equation will be

[tex]5.5+p\leq A\\\Rightarrow 5.5+p\leq 21\\\Rightarrow p\leq 21-5.5\\\Rightarrow p\leq 15.5[/tex]

So, the value of p is in the range of [tex](0,15.5][/tex] or [tex]0<p\leq15.5[/tex].

Answer:

The equation in the standard form is

[tex]y+2x=5[/tex]

Step-by-step explanation:

Given the points

Finding the slope between (6, -7) and (4, -3)

[tex]\left(x_1,\:y_1\right)=\left(6,\:-7\right),\:\left(x_2,\:y_2\right)=\left(4,\:-3\right)[/tex]

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{-3-\left(-7\right)}{4-6}[/tex]

[tex]m=-2[/tex]

As the point-slope form is defined as

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -2 and the point (6, -7)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-7\right)=-2\left(x-6\right)[/tex]

Writing the equation in the standard form form

As we know that the equation in the standard form is

[tex]Ax+By=C[/tex]

where x and y are variables and A, B and C are constants

converting the equation in standard form

[tex]y-\left(-7\right)=-2\left(x-6\right)[/tex]

[tex]y+7=-2\left(x-6\right)[/tex]

subtract 7 from both sides

[tex]y+7-7=-2\left(x-6\right)-7[/tex]

[tex]y=-2x+5[/tex]

[tex]y+2x=5[/tex]

Therefore, the equation in the standard form is

[tex]y+2x=5[/tex]

Answer:

No, because the curve indicates that the rate of

change is not constant.

Im 99.9 sure

Step-by-step explanation:

No, because the curve indicates that the rate of change is not constant.

The graph of a linear function is a straight line. The following is the form of a linear function. a + bx = y = f(x). One independent variable and one dependent variable make up a linear function. X and Y are the independent and dependent variables, respectively.

Given:

From the graph we can write the points as

(1, 0), (2, 25), (3, 50), (4, 100), (5, 150), (6, 200), (7, 290)

Since from the above points we can see that there is no constant rate of change followed by the points which the graph Curve.

Also, the linear function usually have the straight line graph.

Step-by-step explanation:

Answer:

[tex]V=5.23\times 10^8\ m^3[/tex]

Step-by-step explanation:

A large water reservoir can be well modeled with a hemisphere whose radius is 630 meters.

The volume of a hemisphere is given by :

[tex]V=\dfrac{2}{3}\pi r^3[/tex]

Substitute r = 630 m in the above formula

[tex]V=\dfrac{2}{3}\pi \times (630)^3\\\\=5.23\times 10^8\ m^3[/tex]

So, the water reservoir can hold [tex]5.23\times 10^8\ m^3[/tex] of water.

Answer:

1179 yards

Step-by-step explanation:

The question can be described by a right angled triangle.

The angle of depression of the boat from the plane = [tex]90^{o}[/tex] - 58˚

                                                                    = [tex]32^{o}[/tex]

Let the distance from the plane to the boat be represented by x.

Thus, applying the appropriate trigonometric function, we have;

Cos θ = [tex]\frac{Adjacent}{Hypotenuse}[/tex]

Cos [tex]32^{o}[/tex] = [tex]\frac{1000}{x}[/tex]

x = [tex]\frac{1000}{Cos 32^{o} }[/tex]

  = [tex]\frac{1000}{0.8481}[/tex]

  = 1179.11

x = 1179 yds

The plane should be 1179 yards away from the boat.

Answer:

x = -11

Step-by-step explanation:

To find the zero of this function, factor the equation:

g(x) = [tex]x^{2} +22x+121[/tex]

g(x) = (x + 11) (x + 11)

g(x) = [tex](x+11)^{2}[/tex]

The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.
