Carmen is going to roll an 8-sided die 200 times. she predicts that she will roll a multiple of 4 twenty-five times. based on the theoretical probability, which best describes carmen’s prediction? carmen’s prediction is exact because 200 times startfraction 1 over 8 endfraction is 25. carmen’s prediction is low because 200 times one-fourth is 50. carmen’s prediction is low because 200 divided by 2 is 100. carmen’s prediction is high because 200 divided by 25 is 8.
Answers
The expected value is 50 then Carmen’s prediction is low because 200 times one-fourth is 50. Then the correct option is B.
How to calculate the expectation value?Expectation can be taken as a weighted mean, weights being the probability of occurrence of that specific observation.
Thus, if the random variable is X, and its probability mass function is given as
[tex]E(X) = \sum_{i=1}^n( f(x_i) \times x_i)[/tex]
(n is the number of values X takes)
Carmen is going to roll an 8-sided die 200 times.
She predicts that she will roll a multiple of 4 twenty-five times.
The sample will be
Total event = 8 {1, 2, 3, 4, 5, 6, 7, 8}
Then the favorable event will be to roll an 8-sided die and get a multiple of 4. Then we have
Favorable event = 2 {4, 8}
Then the probability will be
[tex]\rm P = \dfrac{2}{8} = \dfrac{1}{4}[/tex]
A dice is rolled 200 times, then by the binomial theorem we have the expected value will be
[tex]E(x) = nP = 200 \times \dfrac{1}{4} = 50[/tex]

Alvarez has $650 deposited into his bank account. The account earns simple interest of 5. 5% per year. No other money is added or withdrawn from the account for a period of four years. What is the total amount of money in the account after four years?
Answers
Answer:
$793
Step-by-step explanation:
The amount of money in an account earning simple interest is given by the formula ...
A = P(1 +rt)
where P is the principal invested at rate r for t years.
__
Using the values given in the problem statement, the account balance can be found to be ...
A = $650(1 +0.055×4) = $650×1.22 = $793
There will be $793 in the account after 4 years.

What is the answer to this 3x+17=-2x-13???
Answers
Answer:
x = -6
Step-by-step explanation:
3x + 17 = -2x - 13
==> add 2x to both sides
5x + 17 = - 13
==> subtract 17 from both sides
5x = -30
==> divide both sides by 5
x = -6
move like terms (remember to change signs)
3x + 2x = -13 -17
5x = -30
get x to equal to the following
x = -30 / 5
x = -6
Sam buys 6 pencils and 5 erasers for a total cost of $1. 60. Sally buys 3 pencils and 3
erasers for a total cost of $0. 90. How much does one ERASER cost?
Answers
Let p = the amount of pencils and e = amount of erasers.
Equation 1. 6p + 5e = $1.60
Equation 2. 3p + 3e = $0.90
If we times equation 2 by 2 to get 6p + 6e = $1.80 and call it equation 3 we can minus equation 1 from it to get equation 4.
Equation 3. 6p + 6e = $1.80
Equation 1. - ( 6p + 5e = $1.60 )
Equation 4. e = $0.20
Therefore an eraser is 20 cents.

Which statements are true about the data sets? check all that apply. set a is symmetrical. set b has the same mean and median. set b is right skewed. set a is left skewed. the median of set a is larger than the mean of set a.
Answers
1) The mean of set A is larger than the mean of set B.
2)The median of set A is larger than the median of set B.
A = {10, 12, 12, 6, 8, 5, 4, 10, 8, 10, 12, 12, 6}
B = {8, 8, 8, 7, 9, 7, 9, 10, 6, 8}
What is the mean?Mean is the ratio of the sum to the total number of observations.
Mean of set A = 115/13
Mean of set B =80/10 =8
So, the mean of set A is larger than the mean of set B.
Arranging both the sets in ascending order
A = {4, 5, 6, 6, 8, 8, 10, 10, 10 12, 12, 12, 12 }
Median of set A = middle term = 7th term = 10
Similarly, the median of set B =8
So, the median of set A is larger than the median of set B.
Thus, 1) The mean of set A is larger than the mean of set B.
2)The median of set A is larger than the median of set B.

Answer:
x = 16/3, y = -1/9
Step-by-step explanation:
4x + 1 = 5(x-3y) - 6
3(x+6y) + 4 = 9y + 19
Simplify both equations
4x + 1 = 5x-15y - 6
-x + 15y = -7
3x + 18y + 4 = 9y + 19
3x + 9y = 15
Now multiply 3 on both sides for the first equation.
(easier for adding both equations)
-3x + 45y = -21
3x + 9y = 15
Add both equations
x cancels out
54 y = -6
y = -1/9
plug in to other equation
3x + 9y = 15
3x - 1 = 15
3x = 16

Have a great day ♡♡♡♡♡For an art project, a cone is covered with paper without any gaps or overlaps. The height of the cone is 28 inches and its diameter is 14 inches.
What is the surface area of the covering to the nearest square inch?
Answers
The surface area of the covering of the cone to the nearest square inches is 788 inches²
Surface area of a conesurface area of a cone = πr(r + l)
where
r = radiusl = slant lengthTherefore,
diameter = 2(radius)
14 = 2r
r = 14 / 2
r = 7 inches
l² = 7² + 28²
l = √49 + 784
l = √833
l = 28.8617393793
l = 28.86 inches
Therefore,
surface area = 3.14 × 7 (7 + 28.86)
surface area = 21.98 × 35.86
surface area = 788.2028

which of the following is an equations of the line passing through the points (-1,4) and (1,2)
Answers
Answer:
y = -1x + 3 or y = -x + 3 (**That is the last option which is D**)
Step-by-step explanation:
You need to do slope-intercept formula and the slope formula.
The Slope-Intercept Formula: y=mx+b
The Slope Formula: y2 - y1 / x2-x1
Your coordinates:
(-1,4) and (1,2)
2 - 4/1- (-1)
-2/2
Simplified is -1
Your "m" in the slope-intercept formula is -1
Formula: y=-1x + b
Now, you need to find the Y-Intercept which is the "b"
Using our slope-intercept formula, you need to plug in "x1" and "y1"
4 = -1(-1) + b
4 = 1 +b
4-1 = b
3 = b
So your equation is:
y = -1x + 3 or y = -x + 3
