A data set consists of 6 different whole numbers. The difference between the largest value and the smallest value is 21 and the median is 40. What is the largest possible mean of this data set?
Answer:
We have a data set with 6 whole numbers:
{A, B. C, D, E, F}
The median, in this case, will be the mean of the two middle numbers, C and D.
Median = (C + D)/2 = 40
We also know that the difference between the largest and the smallest number is 21, where the largest number is F and the smallest number is A, then:
F - A =21.
And the mean will be:
Now we want to take the largest possible numbers such that we end having the largest mean of the whole set, then we can start by taking:
(C + D)/2 = 40
Here we can just take:
C = 39
D = 41
Now our set is:
{A, B, 39, 41, E, F}
Now, A and B should be the largest possible whole numbers (and they must be smaller than 39
The two options are:
B = 38
A = 37
Now our set is:
{37, 38, 39, 41, E, F}
Now, remember that:
F - A = 21
F - 37 = 21
F = 21 + 37 = 58
Then our set will be:
{37, 38, 39, 41, E, 58}
And for E, we should pick the largest number that we could.
In this case, the only restrictions we have for E are that it must be larger than 41, and smaller than 58.
The largest number that meets those conditions is the number 57.
Then our set will be:
{37, 38, 39, 41, 57, 58}
And the mean of this set is:
Mean = (37 + 38 + 39 + 41 + 57 + 58)/6 = 45

Find x so that GJ is parallel to FK if GF=12, HG=6, HJ=8, and JK=x-4.
Answer:
x=20
Step-by-step explanation:
(12+6)/(8+x-4) =6/8
18/(x+4)=6/8
6(x+4) =(18)(8)
(x+4) =(18)(8)/6
x+4 =(3)(8)
x+4=24
x=-4+24

Factor 16a + 72 to identify the equivalent expression
Hey there, thanks for posting your first question!
If you're asked to factor a polynomial, you need to look for the
greatest common factor between the terms that are involved.
The greatest common factor of 16a and 72 is 8 because 8
is the largest number that can divide into both 16 and 72.
The "a" doesn't qualify because it doesn't appear in every term.
So the 8 factors out.
When that happens, we are left with each term divided by that 8
inside a set of parenthses, I'll show you what I mean.
So we have 8(2a + 9).
I divided the 16a by the 8 and 72 by the 8 and if you
distribute it back you will end up with the original polynomial.
So our answer 8(2a + 9).
is a rule that assigns each value of the independent valable to
one value of the dependent variable.
Answer here
Answer:
For different x values ,we get unique y value. So, Yes the Statement is true that , A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

Heights of American adult women are normally distributed with mean 63.6 inches and standard deviation 2.5 inches. Find the height of an adult woman that corresponds to the 80th percentile.
Answer:
65.7
Step-by-step explanation:
Given ;
Mean, m = 63.6
Standard deviation, s = 2.5
80th percentile = 80 / 100 = 0.8
The Zscore corresponding to the 80th percentile ; Z < P = 0.842 (Z probability calculator)
Zscore = (x - m) / s
0.842 = (x - 63.6) / 2.5
0.842 * 2.5 = x - 63.6
2.105 = x - 63.6
x = 63.6 + 2.105
x = 65.705

In 1990, Jamaica's population of 2,466,000 was expected to grow exponentially by 1.1% each year. What is the domain of the exponential function that represents the situation if
1990 represents year 0?
a. y _> 2,466,000
b. all real numbers
c. y_> 0
d. x _>0
Answer:
answer is b they all add up
Step-by-step explanation:
The domain of the exponential function can take values is option (B) all real numbers is the correct answer.
What is an exponential function?Exponential function involves exponents. An exponential function is an function with exponents where the exponent (or) a part of the exponent is a variable. The population increase or decrease can be modeled as exponential function.
For the given situation,
In 1990, Jamaica's initial population,P₀ = 2,466,000
Rate of population growth,r = 1.1% = 0.011
Let x be the number of years
Then the population growth can be written as
[tex]P(x)=P_{0}(1+r)^{x}[/tex] ------- (1)
Now substitute the above values,
⇒ [tex]P(x)=2466000(1+0.011)^{x}[/tex]
For x=0,
⇒ [tex]P(0)=2466000(1+0.011)^{0}[/tex]
⇒ [tex]P(0)=2466000(1)[/tex]
⇒ [tex]P(0)=2466000[/tex]
If we need to find the population growth in future years, we need to use positive values of x.
If we need to find the population growth in past years, we need to use negative values of x.
If we need to find the intermediate values, then we need to use rational numbers.
Hence we can conclude that the domain of the exponential function can take values is option (B) all real numbers is the correct answer.

can someone check behind me if both of these graphs have a slope of 3?
Answer:
No. The slope of Line E is 3/2, and the slope of Line D is 6/8.
Step-by-step explanation:
For line E, let's find two points that the lines go through: (0,4) and (30, 24).
m=30-0/24-4
m=30/20
m= 3/2 or 1.5
Line E does not have a slope of 3.
Line D goes through these two points: (8,9) and (16,15).
m=15-9/16-8
m=6/8 or 0.75
Line D doesn't have a slope of 3.

Read the excerpt from "Bone Detective."
Diane stood in front of a mirror and stuck out her tongue. It looked like a rosy pink welcome mat to her delicate insides. Her usual rubber mold formula was out of the question—too toxic. She wondered, What is safe to swallow, fast and easy to apply, and hardens quickly into a firm mold?
One of her horse-riding pals, a veterinarian named Mary Wright, had the answer: alginate. Mary told Diane that alginate was a pink gummy material used to make molds of teeth. If it was safe for pets, it should be safe for a tiger.
And people, too, Diane thought.
At her lab she mixed the alginate powder with water to form a paste. Standing in front of a mirror, she scooped up a blob and spread it on her tongue. She pressed it down with her fingers to get out any air bubbles. Not bad, she thought. Tastes just like spearmint. She decided to make an extra-thick mold to make it easier to peel off. So, she added another gloopy blog—and another.
With her thickened tongue hanging out, Diane padded around the lab doing odds and ends while the material set. After about 10 minutes, she peeled off the alginate slowly and carefully. It was fragile—bendable and easy to tear—but it made an excellent impression of her tongue.
Which action in the excerpt illustrates that Diane is dedicated to her work?
She makes a mold of her own tongue.
She performs odd jobs around the lab.
She stands in front of the mirror.
She goes horseback riding with a friend.
Answer:
A. She makes a mold of her own tongue.

The answer to this question is 9cm^2, the second answer
Step-by-step explanation:
To find the area of this parallelogram, you have to first find the area of one of the two triangles shown. The formula to solve a triangle is (base * height)/2, so that would be 4.5cm^2 for each triangle, times two for two triangles would be 9cm^2. If you wanted to do it an easier way, just multiply the length of the bottom of the parallelogram with the height. The measures telling you 3.5 are telling you the length of the diagonal line, so don't pay attention to that.

Please help! What are the independent and dependent variables of this problem?
Answers:
Independent Variable = time = tDependent Variable = height = h(t)======================================================
Explanation:
The horizontal axis always represents the independent variable. Often it is x, but in this case, it's t. The time value does not depend on the height. Time does it's own thing.
The height depends on the time value. The vertical axis, or y axis, is always representing the dependent variable. The notation h(t) helps us see that h must be paired with t, in order to find the value of h so to speak. As the time value changes, so does the height of the ball.
