The brain volumes ​(cm cubed​) of 20 brains have a mean of 1141.1 cm cubed and a standard deviation of 122.6 cm cubed. Use the g

iven standard deviation and the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such​ data, would a brain volume of 1376.3 cm cubed be significantly​ high?

I think of a number, if I subtract 10 from my number, then square the result, I get the same answer as if I square my number, th
zheka24 [161]

Answer:

x =5.5

Step-by-step explanation:

The directions say to use x for the number.

"take 10 away from"

x - 10

"then square the result"

(x - 10)^2

"I get the same answer" means the two expressions will be equal to each other.

"if I square my number"

x^2

"then subtract 10 from the result"

x^2 - 10

SET EQUAL TO EACH OTHER.

(x - 10)^2 = x^2 -10

Multiply on the left side.

x^2-20x+100 =x^2-10

subtract x^2 from both sides.

-20x + 100 = -10

subtract 100.

-20x = -110

divide by -20

x = 11/2 or 5.5

CHECK:

(5.5-10)^2=20.25

5.5^2 - 10=20.25

The solutions are f(-2)=12, f(-1)=7, f(0)=2, f(1)=-3 and f(2)=-8

Explanation:

To find the values of f(x), we need to substitute the values for x in the function f(x)=2-5x

For x=-2,

\begin{aligned}f(x) &=2-5 x \\&=2-5(-2) \\&=2+10 \\&=12\end{aligned}

Thus, f(-2)=12

For x=-1,

\begin{aligned}f(-1) &=2-5(-1) \\&=2+5 \\&=7\end{aligned}

Thus, f(-1)=7

For x=0,

\begin{aligned}f(0) &=2-5(0) \\&=2+0 \\&=2\end{aligned}

Thus, f(0)=2

For x=1,

\begin{aligned}f(1) &=2-5(1) \\&=2-5 \\&=-3\end{aligned}

Thus, f(1)=-3

For x=2,

\begin{aligned}f(2) &=2-5(2) \\&=2-10 \\&=-8\end{aligned}

Thus, f(2)=-8

Hence, the solutions are  f(-2)=12, f(-1)=7, f(0)=2, f(1)=-3 and f(2)=-8
