suppose M is the midpoint of FG. find each missing measure.

FM= 8a + 1, FG = 42, a =?

Answers

Answer 1

The value of a is 2.5

As FG is the line and M is the midpoint of the line

  F   ______________·_________________G

                                    M

So by this, we have that

    FG = FM + MG

Where FM = MG as M is the midpoint of the line.

Therefore FG = 2FM

As it is given that FM = 8a + 1 and FG = 42

Now putting the values we have

42 = 2( 8a + 1)

21 = 8a + 1

20 = 8a

a = 2.5

Therefore the value of a is 2.5.

using a systematic sample guarantees that members of each group within a population will be sampled.

Answers

False

Systematic Sampling is a probability sampling method where people or researchers select members of the population in a regular interval.

• For example, by selecting  every 17th person on the list of the population. If the population is in the random order, this can imitate the benefits of random sampling.

• Systematic sampling can help in minimizing biased samples and poor survey results. If there is a low risk for manipulation of data .

• Systematic sampling introduces certain arbitrary parameters in the data. This can cause overrepresentation or underrepresentation of patterns

In systematic sampling, members from a large population are selected according to a random starting and a fixed periodic interval.

Only stratified sampling, where the population is divided into several data, guarantees the member of each group within a population will be sampled.

Answers

Answer:  D)  subtract 15 from both sides

========================================================

Explanation:

15 - 2.5x is the same as 15 + (-2.5)x

Then we can swap the terms to get -2.5x+15

Therefore, the original equation is the same as -2.5x+15 = 40

To solve this equation, we follow PEMDAS in reverse. So instead of starting with the "P", we start with the "S". There's no subtraction operations to undo, so we move onto the "A". There is an additional operation to undo, which is the +15

To undo the +15, we subtract 15 from both sides

-2.5x+15 = 40

-2.5x+15-15 = 40-15

-2.5x = 25

The next step after this would be to divide both sides by -2.5 to undo the multiplication. The -2.5x means "-2.5 times x".

Solving the Question

We're given:

1,-3, 9, -27, 81, -243, ...

The first term is 1. It appears that, to get each consecutive term, we have to multiply the previous term by -3.

i.e. 1 x -3 = -3-3 x -3 = 99 x -3 = -27

Therefore, to get each the next two terms, we have to multiply the previous term by -3.

Therefore, to get each the next two terms, we have to multiply the previous term by -3.

a cell phone company charges an initial price of $400 for a new phone and then $50 each month after the purchase. if c (t) is a rational function that represents the average monthly cost of owning the cell phone, what is the range of the function? r: ℝ r: (–[infinity], [infinity]) r: (0, 400) r: (50, 450)

Answers

The range of the average cost function of a cell phone that has an initial and monthly costs $400 and $50 is r:(50, 400)

Which method can be used to find the range of the average cost function?

Initial price for the cell phone = $400

Charges per month after purchase = $50

The rational function representing the average monthly cost = c(t)

Required; The range of the average monthly cost function, c(t)

Solution:

The total cost of owning the cell phone, C, is therefore;

C = 400 + 50•t

Where;

∆t = The number of months after purchase

The average monthly cost is therefore;

[tex]c(t) = \frac{C}{ \Delta t} [/tex]

At ∆t ≈ 0, we have;

C ≈ 400

The cost for the month at ∆t ≈ 0, is therefore, c(t) = $400

At ∆t ≈ ∞, we have;

[tex] \lim\limits_{∆t→∞} \frac{400}{ ∆t} = 0[/tex]

Therefore;

[tex] \lim\limits_{∆t→∞} c(t) = \frac{400+ 50× ∆t}{ ∆t} ≈ 50[/tex]

Which gives;

The range of c(t) is (50, 400)

The correct option is therefore;

r: (50, 400)

At the beginning of the fall, the water level of a lake is 11 1/3
feet below normal level. After a drought, the lake's water
level dropped 7 2/3 feet. Where is the lake's current water
level in relation to its normal water level?

Answers

The lake's current water is dropped ( 55 / 3 ) feet below the normal water level.

A collection of ordered pairs having one item from each set makes up a relation between two sets. If the ordered pair (x,y) is present in the relation and the objects x and y come from different sets, then the objects are said to be connected. One kind of relation is a function.

Let x be the normal water level of the lake.

At the beginning of the fall, the level of water of the lake is [tex]11\frac{1}{3}[/tex] feet below the water level.

So, the change in water level [tex]-11\frac{1}{3}[/tex].

Then, the water level of the lake dropped [tex]7\frac{2}{3}[/tex] feet after the drought.

Again, the change in water level will be [tex]-7\frac{2}{3}[/tex].

Hence, the total change in water level will be:

[tex]=-11\frac{1}{3}-7\frac{2}{3}[/tex]

= ( - 33 + 1 ) / 3 - ( 21 + 2 ) / 3

= ( - 32 / 3 ) - ( 23 / 3 )

= ( - 55 / 3 )

Therefore, the lake's water level dropped ( 55 / 3 ) feet below the normal water level.

B. D. x < x + 1, because solving it yields an inequality that is True for all real numbers x.

Which inequality represents graph A?

For graph A, as nothing is plotted on the line, we have a inequality with no solution.

The successor of a number(number plus 1), will always be greater than the number, hence the inequality that has no solution is:

A. x > x + 1. because solving it yields an inequality that is False for all real numbers x.

Which inequality represents graph B?

For graph B, as the entire line is plotted, we have a inequality with all real values as solution.

From the same logic above, of the successor, the correct option is:

D. x < x + 1, because solving it yields an inequality that is True for all real numbers x.

While the coordinates of the vertice A' are (5, 7)

If we take the difference between these two coordinate pairs, we will et

A' - A = (5, 7) - (2, 3)
