Answer:

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2.

QF Q6.) Find the function for a.

irakobra [83]

The function for a is (f o g) (x) = 8x^2-10.

Explanation

=========================
$f(x)=2x-4, g(x)=4x^2-3, (f o g)=f(g(x))$

I already knew that the g of x is equal to $4x^2-3$ so I substitute inside of the g of x

$g(x)=4x^2-3$ =======> $f(x)=4x^2-3$ =============> $2(4x^2-3)-4$

simplify it

$2(4x^2-3)-4$ =======> $8x^2-6-4$ =========> $8x^2-10$

$(f o g) = 8x^2-10$

The numbers of pages in the books in a library follow a normal distribution. If the mean number of pages is 180 and the standard

laiz [17]

Answer:

option B.

About 16% of the books have fewer than 150 pages

Step-by-step explanation:

Since we are dealing with a normal distribution

68.27% of the values will fall in the range with the standard deviation

(180-30 , 180+30) = (150, 210)

Approximately 15.86% of the values will be higher than 210

and the rest 15.86% will be lower than 150

So the correct answer is option B.

About 16% of the books have fewer than 150 pages

How can you use volume formulas to solve problems?

Katarina [22]

Well, it depends what shape you are using the volume formula for. If it's for a square (I'm assuming) then the volume formula would be:
