What is one of the distinctions between a population parameter and a sample statis- tic? A. A sample statistic changes each time you try to measure it, but a population parameter remains xed. B. A population parameter changes each time you try to measure it, but a sample statistic remains xed across samples. C. The true value of a sample statistic can never be known but the true value of a population parameter can be known. D. A population parameter is only based on conceptual measurements, but a sam- ple statistic is based on a combination of real and conceptual measurements.

The equation for the graph is y = [tex]2(3)^{x} -5[/tex]  .

An exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.

Standard exponential equation :

y = [tex]a(b)^{x} + k[/tex]

where a is the initial value

b represents the base of the exponential function

x will represent the input of the function

y = k is the single horizontal asymptote

k is  constant

According to the question

The figure in the graph is an exponential graph .

To derive the equation

we will use Standard exponential equation :

y = [tex]a(b)^{x} + k[/tex]  

Now,

There are two points in graph

(0.-3) and (1,1)

k = - 5  ( distance from 0)

now ,

Substituting the values

y = [tex]a(b)^{x} + k[/tex]  

y = [tex]a(b)^{x} -5[/tex]

for point   (0.-3)

-3 = [tex]a(b)^{0} -5[/tex]  

-3 = [tex]a -5[/tex]

a = 2  

for point   (1,1)

1 = [tex]2(b)^{1} -5[/tex]  

1 = 2b - 5

b = 3

Therefore , equation of exponential graph is  

y = [tex]2(3)^{x} -5[/tex]  

Hence ,The equation for the graph is y = [tex]2(3)^{x} -5[/tex]  .

Answer: 171 attendees

Step-by-step explanation:

I answered another similar question by you earlier, so I really hope you read through this explanation, as I will go far in depth.  It's important you learn to do this so as not to simply skate through homework, then struggle with assessment.

For this problem, you have to find something called a unit price.

A unit price is the price in dollars per thing.

In this case, the price in dollars for the whole group is $132 for many things, 66 attendees.

Because 66 attendees costs $132, to find out how much money a single attendee costs, simply divide $132 by 66 to get 2$ for 1 attendee.

With this information, it is very straightforward to determine the number of attendees for $342.  Simply divide $342 by $2 to get 171 attendees.

I really hope it helps :) and please, let me know if you want me to explain in more depth, the unit you are currently in is a fundamental part of early math, and it is important you understand it.

Answer:

2x + 2y = 4  does not belong

Step-by-step explanation:

2x + y = 4     → y = -2x + 4

y = -2x + 4    → y = -2x + 4

f(x) = -2x + 4 → y = -2x + 4

2x + 2y = 4   → y = -x + 2

Answer:

y ≤ -1/3x+80/9

Step-by-step explanation:

(1). 0.75(x)+2.25(y) ≤ 20

0.75 - Number of arcade games (X).

2.25 - Number of snacks (Y).

20 - The total.

(2). 0.75x+2.25y≤20

(After multiplying the x's and y's together, with the numbers).  

(3). 0.75x (-0.75x) + 2.25y ≤ 20 (-0.75x)

(Subtract -0.75x to each side, which allows the equation to get closer to the answer).

(4). 2.25y       -0.75x + 20

   ————   =   ————

    2.25            2.25

(Divide by 2.25 to each side).

(5). y ≤ -1/3x + 80/9

(The result and the inequality).
