Answer and Step-by-step explanation:

Haven't done this in a while, so here we go:

The rule (I'm not really sure) would have to be negative number and negative number.

This means that:

(4, 0) would become (-4, 0) A'

(6, -2) becomes (-6, 2) B'

(8, -7) becomes (-8, 7) C'

and (0, -5) becomes (0, 5) D'

The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard devi

alexira [117]

Answer: 0.8490

Step-by-step explanation:

Given : The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard deviation of 0.9 inches.

i.e. $\mu=30$ and $\sigma=0.9$

Let x denotes the lengths of aluminum-coated steel sheets.

Required Formula : $z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For n= 36 , the probability that the average length of a sheet is between 29.82 and 30.27 inches long will be :-

$P(29.82$

∴ Required probability = 0.8490

Mr. Hedde requires 60% to pass. If someone gets 160 points and falls short by 20

olganol [36]

Answer:

300 points

Step-by-step explanation:

160 + 20 = 180

180 would have been 60 percent

180/60 = 300

300 would have been needed to pass

Proven by:

300 * 60% = 180

180 - 20 = 160

If f(x)=4^x-8 and g(x)=5x+6 find (f+g)(x) ANSWER ASAP PLS

liraira [26]

<h3>Answer: 4^x+5x-2</h3>

Add up the equations and combine any like terms. In this case, the like terms are -8 and +6 which combine to -2. Everything else is unlike terms so you leave them as is.

f(x) + g(x) = (4^x-8) + (5x+6)

f(x) + g(x) = 4^x + 5x + (-8+6)

f(x) + g(x) = 4^x + 5x - 2

Consider the algebraic expression:

GrogVix [38]

Coefficients are the numbers that are next to a variable(a letter in an expression). Therefore the coefficients would be 7 and 18 because they are both next to a variable (y and x).

I can’t exactly remember what a constant is but I think it is a number alone (not next to any variables) and they are ONLY separated by + and - not multiplication or division. In this case it would be all of the numbers that are in between the + or - (all of them.)

I also think a constant could be the variable next to the coefficient. Which would be y and x (next to 7 and 18).

I’m am so sorry I can’t remember what a constant is but I hope the coefficient helps:)
