The correct answer is B.) Eight-grade students

Explanation:

The purpose of a sample is to choose a reduced number of people from a specific population to study and analyze their opinions, behavior, ideas, etc. as part of a research process. Moreover, the sample or individual selected is directly related to the purposes of the research. For example, in research about the opinions of citizens about new policies, the citizens of the specific country or city should be selected.

In this context, eighth-grade students should be selected as part of the sample because this group is directly affected by the theme of the eighth-grade dance. Also, it is the interest of this group the one that determines the final theme rather than all the students or the student government.

Answer:

read explanation

Step-by-step explanation:

rearrange equations to form y=mx+b

-2x+4=2y

-x+2=y

-y=-2x-5

y=2x+5

use these equations to find slope and y intercepts, and match those with the right graph

slope of first: -1

slope of second: 2

y-int of first: 2

y-int of second:5

Please help me with this!!
Ratling [72]

for the first one , send sin^4 (x) to L.H S and then use the identity ( a^2 - b^2 ) = (a+b)(a-b)

you will have the answer in 2 steps literally..

For second one , Add -1 on both sides , leave RHS Untouched.. On LHS , Substitute 1 as sin^2 (x) + cos^2(x) and starting solving by taking common and condensing repeatedly..

The graph shows how many apples Erin can pick if she maintains a constant rate. What is the linear equation for this relationshi
Ainat [17]

Answer:

The linear equation y=50(x) and Erin can pick 50 apples per hour if she maintains a constant rate.

Step-by-step explanation:

To find the linear equation of the relationship from the graph.

We have to find the coordinates .

Let say (x,y)=(1,50) and (x_1,y_1)=(2,100)

Here x variable is the time in hour and y variable is the number of apples.

To find linear equation we have to find the slope (m) of the line by using point-slope form.

m=\frac{y_1-y}{x_1-x}

So,

m=\frac{100-50}{2-1}=50

The the linear equation will be.

   y=50(x)

Number of apples Eric pick in an hour is 50.

By plugging the value of x=1 in the equation we can find the number of apples picked by Erin per hours subsequently x=2 for second hour.

In each hour she picks 50 apples.

Linear equation is  y=50(x) and number of apples picked by Eric in an hour is 50.

In order to join a karate class, you have to pay $10 for registration and then $2 per class. Find the equation that determines t
Black_prince [1.1K]

Answer:

2c + 10 = T

Step-by-step explanation:

Since you already have to pay $10, then that would just be added.

Then it is $2 per class: 2c

So 2c + 10 = the total cost

2c + 10 = T

Hope this helped :)
