Computer packages at an electronics store are priced $1,729.99, $2,249.99, $2,139.99, $1,979.99, and $999.99.
One thousand seven hundred and twenty nine point nine nine comma two thousands two hundred forty nine point nine nine comma two thousand one hundred thirty nine point nine nine comma one thousand nine hundred seventy nine point nine nine comma nine hundred ninety nine point nine nine.
Range is the difference between highest value minus lowest value.
Range=Highest value - Lowest value

Kiran's mother gets a restaurant bill for $25. She has a coupon for 15% off. After the
discount is applied, she adds 20% as a tip.
What is the total after the discount and tip? Explain or show your reasoning.
Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50

Which statement is true of normally distributed data?
A.
Approximately 90% of data falls within 2 standard deviations (±2) of the mean.
B.
Approximately 90% of data falls within 3 standard deviations of (±3) the mean.
C.
Approximately 95% of data falls within 2 standard deviations (±2) of the mean.
D.
Approximately 95% of data falls within 3 standard deviations (±3) of the mean.
Please explain and no answering just for points.
C
have a nice day!!!!!!!!!!!!!!!!!!!!!!!
Approximately 95% of data falls within 2 standard deviations (±2) of the mean. Option D is correct.
What is a normal distribution?A normal distribution is a type of continuous probability distribution for a real-valued random variable such that the values are symmetric about a mean and the curve has bell shape.
Standard deviation is the measure of the randomness of the distribution. The curve has its peak at the mean.
As standard deviation increases, the peak of the curve comes lower and the distribution becomes more and more dispersed.
In a normal distribution 68% of the values falls within 1 standard deviation
and 95% of the values falls within two standard deviations. 99% of the values falls within three standard deviations.
Hence, approximately 95% of data falls within 2 standard deviations (±2) of the mean.

Answer:
If your good at math plz help me
i think this is the answer, hope A(-3)=n-5
==================================================
Work Shown:
[tex]a_1 = -3 = \text{ first term}\\\\d = -5 = \text{ common difference}\\\\a_n = a_1 + d(n-1) = \text{ nth term}\\\\a_n = -3 + (-5)(n-1)\\\\a_n = -3 -5n + 5\\\\a_n = -5n + 2\\\\[/tex]
The common difference is due to us adding -5 to each term to get the next one. Example: -3+(-5) = -8, or -8+(-5) = -13.
--------------------
As a way to check if we have the correct nth term formula, plug in values of n to see if we get the correct sequence value
For instance, if n = 1, then
[tex]a_n = -5n+2\\\\a_1 = -5(1)+2\\\\a_1 = -5+2\\\\a_1 = -3\\\\[/tex]
Which matches with the first term given to us.
Or if n = 2, then,
[tex]a_n = -5n+2\\\\a_2 = -5(2)+2\\\\a_2 = -10+2\\\\a_2 = -8\\\\[/tex]
That matches the second term given to us. I'll let you check the others.

If 2^x3^y=18 and 2^x×3^y=36 then find the value of x and y
Answer:
x = 1
y = 2
Step-by-step explanation:
x=1 and y=2.
step 1 ,
2^2x*3^y=36
3^y= 36/2^2x ———- equal 1
step 2,
put the value of 3^y in 2^x*3^y = 18 (equal 1)
WHEN BASES ARE SAME POWERS ARE SUBTRACTED IN CASE OF DIVISION.
Therefore, 2^x-2^2x= 1/2
2^-x= 1/2
(1/2)^x = 1/2
COMPARING THE POWERS BECAUSE THE BASE IS SAME.
x=1.
Now, putting the value of x=1 in 2^x*3^y = 18
y=2.

What are the like terms in the expression below?
3x + 8 + 3y + 8x
Answer:
3x and 8x are like terms.
Step-by-step explanation:
Like terms are the terms that share the same variables. They do not have to share the same coefficients - or, in other words - the numbers in front of the variable do not have to be the same. Only the variable has to match.
So, looking at the expression, the only two terms that have the same variable are 8x and 3x, which both have the variable x. Therefore, 3x and 8x are like terms.

Find f(-2) for (x) = 2(4)x
Answer:
-16
Step-by-step explanation:
The question asks to find x from 2(4)x if x = -2
All that we have to do is substitute to get our answer :
f(-2) for (x) = 2(4)x
f(-2) = 2(4)(-2)
f(-2) = 2(-8)
f(-2) = -16
Therefore, x = -16
Answer:
-16
Step-by-step explanation:
Plug in -2 for x and then multiply 2 and 4 to get 8 (-2) which is then -16. Hope that helps!
