Population. They are all the people at the theme park.
00:00
Sample. They are a subset of all the people at the theme park.
00:00
Both population and sample. They are all the people at the theme park.
00:00 -
Neither population nor sample. They are not the people at the theme park.

Answer:

Sample

Step-by-step explanation:

The people that are riding the roller coaster are only a select few people out of everyone in the entire park.

If you think about it this way, there are other rides in the park (there might be bumper cars and a Ferris wheel, etc.), so the people on the roller coaster are just a small group of the entire population of people in the park

which of the following is not a way to represent the solution of the inequality 8x − (5x 4) greater than or equal to −31? a. x g
IgorLugansk [536]
8x - (5x + 4) ≥ -31

8x -5x - 4 ≥ -31

3x ≥ -31 + 4

3x ≥ -27

x ≥ - 9

Answer: a numbe line with a circle on - 9 and shading to the left.

Because that drawing represents the number that are less or equel than -9 and the answer is the numbers greater or equal than -9.

Which exponential function goes through the points (1, 16) and (4, 128)?
djyliett [7]

Answer:

Here is the complete question (attachment).

The function which represent the given points are f(x)=8(2)^{x}

Step-by-step explanation:

We know that a general exponential function is like,y=a(b)^{x}

We can find the answer by hit and trial method by plugging the values of (x,y) coordinates.

Here we are going to solve this with the above general formula.

So as the points are (1,16) then for x=1,\ y=16

Can be arranged in terms of the general equation.

ab^1=16...equation(1) and ab^4=128...equation(2)

a\times b=16, then\ a=\frac{16}{a}

Plugging the values in equation 2.

We have

\frac{16}{b} b^4=128,16\times b^3=128,b=\sqrt[3]{\frac{128}{16}} =\sqrt[3]{8}=2

Plugging b=2 in equation 1.

We have a=\frac{16}{b} =\frac{16}{2} =8

Comparing with the general equation of exponential a=8 and b=2

So the function which depicts the above points =y=8(2)^x

From theoption we have B as the correct answer.

Find the 7th term of the geometric progression which begins -6250, 1250, -250....
aleksandr82 [10.1K]

Answer:

a(7) = -0.4

Step-by-step explanation:

The general formula for a geometric progression is a(n) = a(1)*r^(n - 1), where r is the common ratio.  In this problem, a(1) = -6250.  To find r, we divide 1250 (the 2nd term) by -6250 (the 1st term), obtaining r = -0.2.

Then the formula for THIS geometric progression is

a(n) = -6250*(-0.2)^(n - 1).

Thus, the 7th term of THIS progression is

a(7) = -6250*(-0.2)^(7 - 1), or -6250*(-0.2)^6, or -0.4
