The standard deviation of a population is 4.1.
What is the margin of error?
If the standard deviation of a population is 4.1. The margin of error is 16.81.
Margin of error:Given:
Standard deviation=4.1
Hence:
Variance will be the standard deviation square
Variance=Standard deviation²=4.1×4.1
Variance=Standard deviation²=16.81
So,
Margin of error=16.81
Therefore the margin of error is 16.81.

Answer:
I am confused what the question is asking
Step-by-step explanation:
Could you please comment down below and restate the question?
Answer: ok so.. exponential function's is kinda the same process as slopes and linear equations and functions ok so........
For slopes its rise over run but for this question its...... TO BE CONTINUED LOL (go to the explanation)
Step-by-step explanation:
So for the run on the x axis its 7 you can see it goes upward a little bit on the 7 but the 7 still counts :D
ok so we got 7 and as the line rises 9go to the picture added for more understanding) So as the line rises we can see from were i marked it in the picture that it touches the 2. So we got 2 as the rise and 7 as the run but remember this is not slopes lol so its kinda different.

Use the net to find the surface area of the prism
Answer
364 i think
Step-by-step explanation:
find the area of triangles + area of rectangles
area of triangles: b x h x 1/2
6 x 4 x 1/2
= 12
but two triangles, so . double it and then you get 24 for the two triangles areA
area of rectangles;
l x w
22 x 6
= 132
but two up and down rectangles, so double it = 264
now back rectangle:
l x w
22 x 4
= 88
Add it all up together and you have the surface area!
Surface Area - The area of the surface of the 3D object, NOT volume

Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.
What is the probability of Sarah picking a blue marble on 2 consecutive draws without replacement?
Answer: The probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%
Step-by-step explanation:
Given: Sarah has a bag of 100 marbles. 40 are blue, 40 are green, and 20 are purple.
The probability of Sarah picking a blue marble on 2 consecutive draws without replacement = [tex]\dfrac{40}{100}\times\dfrac{39}{99}=0.157575757576\approx15.8\%[/tex]
Hence, the probability of Sarah picking a blue marble on 2 consecutive draws without replacement = 15.8%

The line y=2x+5 would pass through which of the following points?
A(0,2)
B. (0,10)
C. (0,5)
D. (0,7)
Answer:
C: (0, 5)
Step-by-step explanation:
The x-coordinates are all the same: 0. In y = 2x + 5, the 2x term would be zero in all those cases, leaving only the y-intercept (5).
We conclude that the line would pass through (0, 5), which is the y-intercept.

Which answer describes the sequence {1,3,7,15,…} as a mathematical statement? The nth value equals 1 more than twice the first value. The nth value equals 1 more than twice the previous value. The nth value equals the sum of the previous 3 values. The nth value equals 1 more than the sum of the previous value and n. Checkpoint 04 Click on the numbers to jump from one question to another.
Answer:
Step-by-step explanation:
Each new value is 1 plus twice the previous value.
First value is 1. Then,
1 plus twice 1 = 3, the second value.
Second value is 3
1 plus twice 3 = 7, so
Third value is 7
and so on (this is merely a check)
An arithmetic sequence is a sequence in which the difference between any two terms of the sequence is the same or equal. The nth of the series will be aₙ =1 + (n-1)2.
What is Arithmetic Sequence?An arithmetic sequence is a sequence in which the difference between any two terms of the sequence is the same or equal.
aₙ = a₁ + (n-1)d
where,
aₙ is the nth term of the sequence,
a₁ is the first term of the sequence,
r is a common difference between every two terms.
The arithmetic sequence given is 1,3,7,15,…, therefore, the common difference between the series and the value of the first term can be written as,
d = 3-1 = 2
a₁ =1
the nth term of the series can be defined as the,
aₙ = a₁ + (n-1)d
aₙ =1 + (n-1)2
Hence, the nth of the series will be aₙ =1 + (n-1)2.
