Answer:
174000
Step-by-step explanation:
Hello,
Let's assume f the age of the father,
s the age of the son.
<span>The age of a father is 2 less than 7 times the age of his son ==> f=7s-2 (1)
</span>
<span>In 3 years, the sum of their ages will be 52 ==>(f+3)+(s+3)=52 (2)
(2)==>f+s+6=52
==>f+s=46 (3)
(3) and (1) ==>7s-2+s=46
==>8s=48
==>s=6
f=46-6=40
</span>
for f(x) = -2(x-4)2+2 - set equation to y = -2(x-4)2+2, solve x-4=0, x = 4
axis of symmetry is x = 4
for g(x) = 5x2-10x+7, set equation to y = 5x2-10x+7, solve the square: 5x2 becomes 5(x-1)2 solve x-1 = 0, x = 1
axis of symmetry is x=1
for H(x) what x value would be the centerline so that the graph symmetry is the same on both sides? looking at the graph the top of the arc is on -2
so axis of symmetry is x = -2
Answer:
Step-by-step explanation:
Given that you have been discussing a research project with your friend Connor. Connor has told you that his research hypothesis states, the mean of population 1 is not equal to the mean of population 2.
So our null hypothesis should be

This is a two tailed test
How we write in symbols is shown in Ha as above.
not equal to sign is used here to represent.
First, let's simplify the equation.



- Apply the Distributive Property to the right hand side of the equation

- Subtract
from both sides of the equation
Since the right and left sides of the equation are equal, we know that there must be an infinite number of solutions. This means that there is an infinite amount of values that we can substitute for
for the equation to be true.
