Answer: D. A or B depending on the distribution of the sample

Step-by-step explanation:

Given: A question ask about how many hours per week do you watch television?

Total participants = 300

Since all participants are different ,  so have their own answer to this question in numerical terms.

We use proportion or percentage to summarize data if data is categorical, but here data is numerical (continuous).

here , we can use either mean or median ( if it has outliers).

For this we need to check the distribution of the data, if it is normal then Mean, standard deviation, and range would be a better option (as mean is the best measure of tendency)otherwise Median, IQR, and range would be a better option .

hence, the correct option is D. A or B depending on the distribution of the sample

Answer:

x=84

Step-by-step explanation:

144/12 = 60/12 + x/12

12=5+x/12

12-5=x/12

7=x/12

x=84

Hey there! I'm happy to help!

A is -10 and F is -5. To find the number in between two numbers, you add them and divide by 2.

-10+(-5)=10-5=-15

-15/2=-7.5

So, the midpoint is -7.5, which is right in between C and D.

Have a wonderful day! :D

Answer: im pretty sure its D. 4

Step-by-step explanation:

Answer:

the probability is:

P(A) 2/6 =1/3

Now let's take rolling a prime number:

A prime number is a natural number greater than 1 which can only be divided without a remainder by 1 and itself. So from the numbers on the cube prime numbers are:

2, 3 and 5. The probability of getting a prime number in a single roll is:

P(B) =3/6=1/2

Now to calculate the probability of A and B

you have to multiply both probabilities:

P(A-B)=P(A) . P(B) = 1/3 . 1/2 = 1/6

Answer:

738,378,886

Step-by-step explanation:

1) Add 2+99,999,999 which equals to 100,000,001

2) Then, subtract 100,000,001 with 7 which is 99,999,994

3) Finally, add 99,999,994 with 638,378,892 which is 738,378,886

Answer:

k=-4

Step-by-step explanation:

[tex]\frac{6}{5} (8*-4+2) = -36[/tex]

Answer:

k = -4

Step-by-step explanation:

6/5 (8k + 2) = -36

5 x 6/5 (8k + 2) = -36 x 5

6(8k + 2) = -180

48k + 12 = -180

48k = -180 - 12

48k = -192

48k/48 = -192/48

k = -4

Answer:

1. [tex]f(x)=x^{2}[/tex] and [tex]g(x)=-\sqrt{x}[/tex]

2. Vertical Asymptote: x=-4

    Horizontal Asymptote: y=1

    Zeros: (-2,0)

    Because the graph will have a hole at x=-1. This is, the graph is not defined for that particular x-value.

3.  [tex]f(x)=x^{2}+4[/tex]

It has two complex roots, so there is no place in the graph where it crosses the x-axis.

Step-by-step explanation:

1. If we find the composite function f[g(x)] with the functions:

[tex]f(x)=x^{2}[/tex] and g(x)=-x, we will get the following:

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

which simplifies to

f[g(x)]=x

on the other hand, if we find g[f(x)] we will get the following:

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

which simplifies to:

g[f(x)]=-x

2.

Before finding the asymptotes, it's a good idea to factor both the numerator and denominator of the function, so we get:

[tex]f(x)=\frac{x^{2}+3x+2}{x^{2}+5x+4}[/tex]

[tex]f(x)=\frac{(x+2)(x+1)}{(x+4)(x+1)}[/tex]

we can now see that this function can be simplified. It is important to simplify this function so we don't confuse vertical asymptotes with holes in the graph, so when simplifying we get the following:

[tex]f(x)=\frac{x+2}{x+4}[/tex]

now we can set the denominator equal to zero.

x+4=0

and solve for x:

x=-4 this is our vertical asymptote.

For the horizontal asymptote, there is a rule that tells us that if the polynomials on the numerator and denominator have the same degree (the same greatest power), then the horizontal asymptote is found by dividing the lead coefficient of the polynomial on the numerator by the lead coefficient on the denominator. In this case the lead coefficients are 1 and 1 so the horizontal asymptote is:

[tex]y=\frac{1}{1}[/tex]

so the horizontal asymptote is at:

y=1.

The zeros of the function are located at the x-values that will turn the numerator of the simplified fraction equal to zero, so we get:

x+2=0

x=-2

so the only zero will be located at (-2,0)

x=-1 is not a zero because the original function is not defined for x=-1, there is a hole in the graph at this x-value.

Take a look at the graph of the function (See attached picture)

3.

This will happen when there are no real zeros. Take for example the function:

[tex]f(x)=x^{2}+4[/tex]

In this case this problem has 2 non-real zeros:

[tex]x^{2}+4=0[/tex]

[tex]x^{2}=-4[/tex]

[tex]x=\sqrt{-4}[/tex]

so:

x=2i   or   x=-2i

since they are complex numbers they cannot be graphed on a coordinate axis, so the graph will not cross the x-axis. See attached picture.

Step-by-step explanation:

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = ⅔x + 4

Comparing with the general equation above

Slope = 2/3

Since the lines are parallel their slope are also the same

Slope of parallel line = 2/3

Equation of the line using point (-7 , 1) and slope 2/3 is

[tex]y - 1 = \frac{2}{3} (x + 7) \\ y - 1 = \frac{2}{3} x + \frac{14}{3} \\ y = \frac{2}{3} x + \frac{14}{3} + 1[/tex]

We have the final answer as

Answer:

x=16

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x−8+3x−12=60

2x+−8+3x+−12=60

(2x+3x)+(−8+−12)=60(Combine Like Terms)

5x+−20=60

5x−20=60

Step 2: Add 20 to both sides.

5x−20+20=60+20

5x=80

Step 3: Divide both sides by 5.

5x
