A) y=4x-6
EXPLANATION:
You can see on the y axis, the line meets at -6, which you can eliminate B,C and D immediately. But to be sure, look where the line meets again on the graph. Your point should be (1,4), you had to go over one, and up 4 to get to the next point.

1.)
The term (2+8) is the amount of fabric Ali bought. You know this because in the problem, it says that she buys “2 white pieces and 8 blue pieces”

2.)
The terms of the equation are
k and 2f

These are the terms because they are separated by the addition sign

3.) $36
You would first find rate per sand which. To find this, you would do:
9/2
This will give you
4.5. Now, you multiply that by 4. That gives you 36.

4.) The skateboard costs 150

How?
30 is 20% of the price. 20x5=100. So, to find the total amount, you would multiply 30 by 150.

5.) About 50 miles an hour.
You always put distance over time. If you do:
400/8
You get the average rate of 50

6.) 5n

How?
Well, there are five cents in every nickel. So, to find out how many pennies, you would multiply the amount of nickels by 5.

tatuchka [14]

Answer:

a)= 2

b) 6.324

c) P= 0.1217

Step-by-step explanation:

a) The mean of the sampling distribution of X`1- X`2 denoted by ux`-x` = u1-u2 is equal to the difference between population means i.e = 2 ( given in the question)

b) The standard deviation of the sampling distribution of X`1- X`2 ( standard error of X`1- X`2) denoted by σ_X`1- X`2 is given by

σ_X`1- X`2 = √σ²/n1 +σ²/n2

Var ( X`1- X`2) = Var X`1 + Var X`2 =  σ²/n1 +σ²/n2

so

σ_X`1- X`2 =√20 +20 = 6.324

if the populations are normal the sampling distribution X`1- X`2 , regardless of sample sizes , will be normal with mean u1-u2 and variance σ²/n1 +σ²/n2.

Where as Z is normally distributed with mean zero and unit variance.

If we take X`1- X`2= 0 and u1-u2= 2  and standard deviation of the sampling distribution = 6.324 then

Z= 0-2/ 6.342= -0.31625

P(-0.31625<z<0)= 0.1217

The probability would be 0.1217
