Answer:

(gof) (4) = 9

Hence, option A is true.

Step-by-step explanation:

f(x)=-x³

g(x)=|1/8x -1|

(gof) (4) = g{f(4)}

First wee need to determine f(4)

f(4)=-(4)³

= -64

(gof) (4) = g{f(4)} = g(-64)

= $\left|(1)/(8)\left(-64\right)-1\right|$

$=\left|-(1)/(8)\cdot \:64-1\right|$

$=\left|-8-1\right|$

$=\left|-9\right|$

$\mathrm{Apply\:absolute\:rule}:\quad \left|-a\right|=a$

$=9$

Thus,

(gof) (4) = 9

Hence, option A is true.

Answer:

900

Step-by-step explanation:

10 x 90 = 900

90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 + 90 = 900

In the checksums, you validated that the average SAT score for all of the records is 1,059.07. When we work with the data more rigorously, several tests will require us to transform NULL values. If you were to transform the NULL SAT values into 0, what would happen to the average (would it stay the same, decrease, or increase?

Answers

Answer:

It would decrease.

Step-by-step explanation:

The null almost always acts like a placeholder where there is nothing to record for that entry, we can say that it is a dummy character.

The difference between null and zero is that zero has a value in a context whereas null does not have any value.

So given the example in the question, if we replace the null values with zeros, that would affect the average because of the fact that zero values are going to get included in the average, null values were not included. Therefore this will result in the average being decreased.

The floor of a shed given on the right has an area of 44 square feet . The floor is in the shape of a rectangle whose length is 3 less than twice the width. Find the length and width of the floor of the shed.

Answers

Answer:

The length and width of the floor of the shed are 8 feet and 5.5 feet, respectively.

Step-by-step explanation:

Given that the shape of the shed is a rectangle, the expression for the area is:

$A = w \cdot l$

Where $w$ and $l$ are the width and length of the shed, measured in feet. In addition, the statement shows that $l = 2\cdot w - 3\,ft$ . Then, the equation of area is expanded by replacing length:
