Answer:
no it's not
Step-by-step explanation:
6(2r+(-1)+1 = 12r + -6 + 6 = 12r+ 0 => not equivalent to 12r - 5
Hope this help :)
Answer:
x=1
y= -1
z=2
Step-by-step explanation:
x+y+z=2 and x-y-2z=6
if z=2 then
x+y+2=2 and x-y+4=6
and these become
x+y=0 and x-y=2
usign linear cancellation method we get
2x=2
dividing both sides by 2 we get
x=1
then going back to one of the original equations and plugging x=1 and z=2 we get
1+y+2=2
solving for y we get
y= -1
Answer:
The diameter is 14π
Step-by-step explanation:
We know the area of a circle is πr^2
let 49π=πr^2
Cancel the π's, and you get 49=r^2
Take the square root and you get r=7
The diameter of a circle is 2πr.
2π(7)=14π.
Answer:
Hₐ = P ( 1 ) > 1/6
Step-by-step explanation:
This is the answer because the question is asking you for the "alternative hypothesis" and that means that it's basically asking for the statement that agrees with what is being said.
Since we know that a student believes that he's seeing the number "1" too often, then we must find the equation that agrees with that statement, which is Hₐ = P ( 1 ) > 1/6.
P.S - I took the test and got a 100%.
