Let f(x) = -2x - 7 and g(x) = -4x + 3. Find (f o g)(-5)

The answer is: [A]: " -53 " .
_______________________________________________________
Explanation:
_______________________________________________________
Given:

" Let f(x) = -2x −<span> 7 and g(x) = -4x + 3. Find (f o g)(-5) " ;
_______________________________________________
First, find g(-5) . g(x) = -4x + 3.

g(-5) = -4*(-5) + 3 = 20 + 3 = 23 ;
_______________________________________________
Now find f (g(-5) to get the answer; that is f(23);
_______________________________________________
Find f(23). f(x) = -2x </span>− 7 .

f(23) = (-2*23) − 7 = -46 <span>− </span>7 = -53 ; which is "Answer choice: [A]" .

I would like to know the answer for this question

g100num [7]

To put words into equations:
x+y+z =50
x=4y
4y=5z -> z= 4/5 y

Which means
4y+y+ 4/5 y= 50
29/5 y =50
29y=250
Y=29/250

A polling organization asked a nation-wide random sample of 1600 new brides (those who got married in the past 2 years) the foll

iren [92.7K]

Answer:

It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.

Step-by-step explanation:

Given that:

sample size n = 1600

sample mean $\overline x$ = 20000

standard deviation = 5000

The objective is to choose from the given option about what most closely resembles the relevant box model.

The correct answer is:

It has millions of tickets. On each ticket is written a number a dollar amount. The exact average and SD are unknown but are estimated from the sample to be $20,000 and $5,000 respectively.

However, if draws are made without replacement, the best estimate of the average amount for the bride will be $20,000

Similarly, the standard error for the sample mean = $\dfrac{s}{\sqrt{n}}$
