Answer:
26.5
Step-by-step explanation:
The standard deviation of 22, 29, 21, 24, 27, 28, 25, 36 is 19.75.
What is standard deviation ?"The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean."
"Standard deviation is an especially useful tool in investing and trading strategies as it helps measure market and security volatility—and predict performance trends. As it relates to investing, for example, an index fund is likely to have a low standard deviation versus its benchmark index, as the fund's goal is to replicate the index."
The given numbers are 22, 29, 21, 24, 27, 28, 25, 36.
The formula for standard deviation is [tex]\sqrt({ $\sum_{n=1}^{n} (xi - mean)^2/n )= 1$}[/tex]
Finding mean of given numbers = 22+29+21+24+27+28+25+36/8 = 26.5
Now for standard deviation =[tex]\sqrt((22-26.5)^2 + (26.5-29)^2 + (26.5-21)^2+(26.5-24)^2+(26.5-27)^2+(26.5-28)^2+(26.5-25)^2+(26.5-36)^2/8 )[/tex]
= 19.75
Hence, the standard deviation of the given numbers is 19.75

5x - y = 10
3x - 2y = -1
what is the solution
Answer:
I believe the answer is
(x,y)=(3,5)
The function f(x)=2+e^x has an asymptote at ________.
As x approaches negative infinity, the e^x term slowly approaches 0
This means 2+e^x approaches 2+0 = 2
So that's why we have a horizontal asymptote at y = 2
The graph approaches the line y = 2 but doesn't touch or cross it. Think of it like an electric fence.
The graph is below.

Heres my guess on it, he can feed around 301 people
Step-by-step explanation:
I think you would first find out how much it would cost to feed 1 person, which can be done by taking 18.45/3. It will equal around $6.15. then you would take that number and divide by the money he is willing to spend, which is 1850
(1850/6.15)
You get 300.81 which can round to around 301 people

If m CDE=(3x+10)° m CDF=(x+25)°, and m EDF= 65°. Find m CDF
m∠CDF + m∠EDF = ∠CDE
[tex]x + 25° + 65° = 3x + 10[/tex]
[tex]x + 90° = 3x + 10[/tex]
[tex]90° = 3x + 10 - x[/tex]
[tex]90° = 2x + 10[/tex]
[tex]2x + 10 = 90[/tex]

-2 2
4<−4
−6< −5
================================================
Explanation:
Let's go through the answer choices
A) This is false because -2 is actually larger than -5. Make a number line and you'll see that -2 is to the right of -5. Numbers on the right are larger than numbers on the left. B) This is also false. The value 0 is smaller than 2. A number line might help show this.C) Also false. It should be 4 > -4. Any positive number is always larger than any negative number. D) This is true. On a number line, -6 is to the left of -5, so -6 is smaller than -5. This makes -6 < -5 a true statement.Help asap please! 10 points, friend request, brainliest, thanks, 5 star rating for the first answer! 10 points, friend request, thanks, 5 star rating for 2 answer!

Which equation could be used to find the value of x?
Triangle DEF where angle E is a right angle. DE measures 55. EF measures x. Angle D measures 49 degrees.
cos 49° = x over 55
tan 49° = x over 55
cos 49° = 55 over x
tan 49° = 55 over x
The answer is tan 49° = x over 55 (I got it correct on my quiz).
