Answer: w=−xy+x/y
Step-by-step explanation:
Let's solve for w.
w=
x
y
−x
Step 1: Multiply both sides by y.
wy=−xy+x
Step 2: Divide both sides by y.
wy
y
=
−xy+x
y
w=
−xy+x
y
Answer:
F=122 g=58 h=122
Step-by-step explanation:
F and h have same angle
H is same angle as 58
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
Answer:
Its D
Step-by-step explanation:
Becasue the first one says flip to 180 and that would go into the wrong quadrant.
cant be the second becasue it says to flip on the y axis and you cant do that, it would go into the wrong qaudrant.
it isnt the third one because it says to flip against x. BUT its says to move right... your suppose to be going to the left
So therefor its the last one
Jope that helps :)
Well 106 divided by 7 is 15 so 15 times 7 is 106
