Answer:
165 years old
Step-by-step explanation:
For now let his age be = x
According to the question,
4x - 500 = 160
4x = 160 + 500
4x = 660
x = 660 / 4
x = <u>165 years old</u>

Answer:
0.0060
Step-by-step explanation:
The z-score is given by
<em>z = (866,475-722,500)/57,429 = 2.51
</em>
The probability is given by the area under the Normal curve N(0,1) to the <em>right</em> of 2.51
In <em>Excel </em> this value is found with the formula
=1-NORMDIST(2.51,0,1,1)
and in <em>OpenOffice Calc
</em>
=1-NORMDIST(2.51;0;1;1)
<em>
(NORMDIST(2.51;0;1;1) gives the area to the left of 2.51, so 1-NORMDIST(2.51;0;1;1) gives the area to the right of 2.51)
</em>
and equals 0.0060
Assuming you want the inverse of f(x)=x²-2,
f(x)=x²-2
repalce f(x) with y
y=x²-2
switch x and y
x=y²-2
solve for y
x=y²-2
x+2=y²
√(x+2)=y
replace y with f⁻¹(x)
f⁻¹(x)=√(x+2)
the inverse is √(x+2)
I think the answer is 24x-5
Y-6=-6(x+5)
y-6=-6x-30
y=-6x-24 is the answer
