Answer:

Selecting whether each variable is discrete or continuous:

Discrete Variables:

The number of college football games ever attended

The number of sons or daughters

The number of countries ever visited

The number of pets currently living in the household

Continuous variables:

Pounds of chocolate consumed in the past year

Shoe size

Height in inches

Step-by-step explanation:

The researcher can distinguish a discrete variable from a continuous variable by checking if the value of the variable can be counted or measured.  The researcher can count the value of a discrete variable, and she can measure the value of a continuous variable.  In other words, a discrete variable represents countable objects and a continuous variable represents measurable amounts.

Using variable concepts, we have that the discrete variables are:

The continuous variables are:

The variables that are countable, that is, discrete, are:

The ones that can assume decimal values, hence being continuous are:

Answer:

[tex]\displaystyle m\angle AED=32.5^\circ[/tex]

Step-by-step explanation:

Angles in a Circle

An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.

Segments AE and DE are secants of the given circle. They form an exterior angle called AED.

The measure of an exterior angle is equal to half the difference of the measure of their intercepted arcs.

Intercepted arcs in the given circle are AD=113° and BC=48°. The exterior angle is:

[tex]\displaystyle m\angle AED=\frac{AD-BC}{2}[/tex]

[tex]\displaystyle m\angle AED=\frac{113^\circ-48^\circ}{2}=\frac{65^\circ}{2}[/tex]

[tex]\displaystyle m\angle AED=32.5^\circ[/tex]

Answer:

The average number of machine cycles per instruction for this microprocessor is 5.8.

Step-by-step explanation:

To find the average number of machine cycles per instruction for this microprocessor, we multiply each number of cycles for it's relative frequency.

We have that:

25% require 2 cycles.

20% require 3 cycles.

17.5% require 4 cycles.

12.5% require 8 cycles.

25% require 12 cycles.

So the average number is:

[tex]M = 0.25*2 + 0.2*3 + 0.175*4 + 0.125*8 + 0.25*12 = 5.8[/tex]

Answer:

120

Step-by-step explanation:

It's NOT 100.

similar shapes have the same angles

so angle "D" is equal to angle "G"

Answer:

D 60° is the correct answer.

because: It is equilateral triangle

(triangle, which's sides and angles are equal)

if sides are equal, angles are equal too.

or

if we have two angle guven, then subtract their addition from 180° to get third angle.

Answer:

The inverse of this function is:

[tex]f(x) = \sqrt[3]{x + 4} - 2[/tex]

Step-by-step explanation:

To find the inverse function, we can simply swap x and f(x) and solve for the latter:

[tex]x = (f(x) + 2)^3 - 4\\x + 4 = (f(x) + 2)^3\\\sqrt[3]{x + 4} = f(x) + 2\\f(x) = \sqrt[3]{x + 4} - 2[/tex]

Answer:

512 cube inches

Step-by-step explanation:

The radius of volleyballs is 4 inches, thus;

diameter of the balls = 2 x radius

                                   = 2 x 4

                                   = 8

The diameter of each ball is 8 inches.

Since the box has the shape of a cube, the smallest box that can hold a volleyball would have its dimensions equal to the diameter of the balls.

So that for the cube,

length = width = height = 8 inches

volume of a cube = [tex]l^{3}[/tex]

volume of the smallest box = [tex]8^{3}[/tex]

                           = 512 cube inches

The volume of the smallest box that can hold a volleyball is 512 cube inches.

Answer:

100.3

Step-by-step explanation:

Area of parallelogram = 10 * 5 = 50 (As to find the area of a parallelogram, you would need to multiply the height and base: just like a rectangle)

We now have to work out the area of the two semi-circles. Both semi-circles have the same diameter which is 8, which means the semi circles are of the same size. Therefore we would just need to work out the area of 1 semi-circle and apply it to the second semi-circle (if that makes sense).

Area of semi-circle = 1/2(πr2 ) --> The '2' is supposed to be squared of r

radius = 8/2 = 4

1/2 (π*4*4)

Put that in calculator and should equal = 8π (Area of 1 semi-circle)

Area of 2 semi-circles  = 8π + 8π = 16π

Total Area = (Area of parallelogram) + (Area of 2 semi-circles)

TA = 50 + 16π

Total Area (Nearest tenths place): 100.3

Step-by-step explanation:

Answer:

-2 2/3,   -2.5,   1.3,  1 1/2,   3

Step-by-step explanation:

So least to greatest

First we should look at the negatives

The smallest number is -2 2/3

The second smallest number is -2.5

The third smallest number is   1.3

The fourth smallest number is   1 1/2

The last number should be the biggest number which would be 3 in this problem

To make this easier you can convert all the fraction to decimal points too

-2 2/3 would be around -2.66

1 1/2 would be 1.5

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251

Step-by-step explanation:

Step(i):-

Given mean of the Population = 25cm

Given standard deviation of the Population = 2.60

Let 'x' be the random variable in normal distribution

Given x=22

[tex]Z = \frac{x-mean }{S.D} = \frac{22-25}{2.60} = -1.15[/tex]

Step(ii):-

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22) = P( Z<-1.15)

             = 1-P(Z>1.15)

             =  1-( 0.5+A(1.15)

             =  0.5 - A(1.15)

             = 0.5 - 0.3749

             = 0.1251

The probability of randomly selecting a rod that is shorter than 22 cm

P(X<22)  = 0.1251
