Write an exponential function to model the following situation: A population starting at 740 animals
decreases at an annual rate of 12%. Use your function to determine about how many animals there will
be after 5 years.
A. 390
B. 150
CC. 680
D. 340
Answer:
A. 390
Step-by-step explanation:
An exponential function can be written in the form [tex]f(n)=a\times b^n[/tex], where [tex]a[/tex] is your starting population, [tex]b[/tex] is the factor by which the population increases, and [tex]n[/tex] is the number of terms. In this case, [tex]a=740[/tex], [tex]b=0.88[/tex] because the population decreases by 12 percent (1-0.12=0.88), and [tex]n=5[/tex].
Thus, [tex]f(5)=740 \times 0.88^5[/tex], which is roughly equal to 390.
Find the value of x and the measure of each angle:
Answer:
m<M= 85° m<N= 85°
Step-by-step explanation:
To find the value of x we should...
Sum of all angles = 360°
95+95+10x-5+8x+13 = 360
198+18x = 360
18x = 360-198
18x = 162
x = 162÷18
x = 9
m<M = (10×9)-5 = 90-5 = 85°
m<N = (8×9)+13 = 72+13 = 85°
PLZZZ MARK ME AS BRAINLIEST PLZZZ
Answer:
x = 9
∠M = 85°
∠N = 85°
Step-by-step explanation:
360 = 95 + 95 + (10x-5) + (8x + 13)
reduce:
18x = 162
x = 9
∠M = 85°
∠N = 85°
A company has 12,247 customers they extend credit to, how many total A/R will they have (just type the number, no commas)
Answer:
12247
Step-by-step explanation:
Accounts receivables A/R are the amounts that will be collected from customers to whom goods are sold on credit.
Now, since there are 12,247 customers to whom the credit has been extended to, there will be equal number of 12,247 accounts receivable in their books and a single GL (General ledger) will be there representing and showing the total amount due from these 12,247 customers.
that is, the company will have to make 12,247 accounts receivable accounts, each having the names of the respective customers.
A data set has these values: 10, 12, 12, 14, 14, 14, 14, 16, 16, 18. The

A. It has a median of 14
B. It is symmetric
C. It has a range of 19.
D. It has a mode of 14
The correct statement which does not describe the data set is,
⇒ It has a range of 19.
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
A data set has these values:
⇒ 10, 12, 12, 14, 14, 14, 14, 16, 16, 18
Hence, We get;
Range = 18 - 10 = 9
Median = 10/2 + 1 term
= 5 + 1 term
= 6th term
= 14
Thus, The correct statement which does not describe the data set is,
⇒ It has a range of 19.

How can I find what the question is looking for?
Answer:
m<N = 130°
m<K = 50°
x = 28
Step-by-step explanation:
angle N and angle K are supplementary so the sum of their measures is 180°
4x + 18 + 2x - 6 = 180 add like terms
6x + 12 = 180 subtract 12 from both sides
6x = 168 divide both sides by 6
x = 28 to calculate the measurements of angle N and K replace x with 28
N = 4x + 28 so 4 × 28 + 18 = 130°
N = 2x - 6 and 2×28 - 6 = 50°
6x = 2y - 7 what is the terms
Answer:
y = 3x+7/2, and x = (2y-7)/6

2 x 2 x 3 = 12
then multiply the total volume by 2/3
12 x 2/3 = 8
That leaves you with the total cubic feet of sand he would need.

A pharmaceutical company is developing a new oral medication for the treatment of psoriasis, a skin disease marked by red, itchy, scaly, patches. Describe how you could design a controlled experiment to test the effect of the medication. How could you keep participants from knowing whether or not they were in the treatment group?
Let's say we had a sample of 100 people. We'll split them into two equal groups of 50 each. The two groups will be the treatment and control groups. The treatment group, aka experimental group, is where the actual drug is given. The control group is where the fake drug is given. People in the control group must not know the pill is fake. For more info, check out the placebo effect. In short, this is when a person takes a fake pill and thinks they get better, and that positive mentality helps them actually get better.
If both the treatment and control groups improve (on average) together, then that means the fake pill is just as good as the real thing. Consequently, it means the real pill isn't effective at all. If on the other hand the experimental group does better overall compared to the control group, then we can see that the real pill is doing what it's intended to do. Of course, there are a lot of complicated factors involved, as there is with anything dealing with medicine. I haven't mentioned anything about side effects or things of that nature. In this simplified viewpoint of the world, we're only considering the one factor of whether or not the drug clears up the psoriasis on the skin.
To make things fair, it's best to randomly generate numbers so that you randomly assign people into each group. That way you have representative samples. Also, when drawing the sample of 100 people, make sure that's as random as possible to help represent the population as best as possible. The fact that the people in the control group not knowing that they are taking the fake pill means we have a single blind experiment. A double blind experiment is when even the researchers are not sure who is taking the real pill vs the fake pill. Double blind experiments are encouraged to prevent the researcher's bias from affecting the results.
To keep participants from knowing whether or not they are in the control group, the common solution is to provide a sugar pill. The pill will not cause any side effects and will not cause any improvements to health. It's simply sugar. To the participant, it seems like the real thing since they can't taste the difference or detect anything seems different.
Answer:
Randomly select a sample of people with psoriasis. Randomly assign them to one of two groups. Give one group the treatment, and withhold it from the other group. Give both groups similar looking pills, so neither knows which group they are in.

Points D and E are midpoints of the sides of triangle
ABC. The perimeter of the triangle is 48 units.
What is the value of t?
2
3
6
8
*ANSWER IS 2 just took the test*
Answer:
A. 2
Step-by-step explanation:
From the diagram, it is indicated;
AD = DB = 3t,
AC = 7t + 6
CE = EB = 4t
Perimeter = 48 units
Perimeter = AD + DB + AC + CE + EB
Plug in the values
48 = 3t + 3t + 7t + 6 + 4t + 4t
Add like terms
48 = 21x + 6
48 - 6 = 21x + 6 - 6
42 = 21x
42/21 = 21x/21
2 = x
x = 2

Tiffany surveyed some of her classmates to find the number of times they wrote the weekly spelling words. She also found the number of words they missed on the spelling test. The scatterplot shows the results of Tiffany’s survey. Which statement does NOT match Tiffany’s scatterplot?
Options :
A.) A student who missed 2 words on the test wrote each word 4 times.
B.) A student who wrote each word once missed 6 words on the test.
C.) A student who did not write the words missed 8 words on the test.
D.) A student who missed 4 words on the test wrote each word 3 times.
Answer:
A student who did not write the words missed 8 words on the test.
Step-by-step explanation:
From the scatter plot, we could identify all the other points except that of option C.
For option A : (4, 2) is a marked point on the graph
For option B : (1, 6) is also a marked point on the graph
For option C : (0, 8) is not a marked point on the graph and hence, does not match Tiffany's scatter plot.

Which table represents a direct proportion between the number of tickets sold and the total cost?

The table represents a direct proportion between the number of tickets sold and the total cost will be D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
For the linear relationship, the slope will remain constant.
Let's check all the options, then we have
A. The slope is given as,
m = (2 - 0) / (1 - 0) = (4 - 2) / (3 - 1)
m = 2 ≠ 1
B. The slope is given as,
m = (4 - 0) / (2 - 0) = (6 - 4) / (4 - 2)
m = 2 ≠ 1
C. The slope is given as,
m = (7 - 5) / (2 - 1) = (9 - 7) / (3 - 2) = (11 - 9) / (4 - 3)
m = 2 = 2 = 2
The y-intercept is 3.
D. The slope is given as,
m = (18 - 9) / (2 - 1) = (27 - 18) / (3 - 2) = (36 - 27) / (4 - 3)
m = 9 = 9 = 9
The y-intercept is zero.
The table addresses an immediate extent between the number of tickets sold and the all-out cost will be D.
