What is the probability of rolling a sum of 14?
Answer: 7.0%
Step-by-step explanation:
The probability of rolling a sum of 14 is 7.0% because 15/216 = 7.0%
The probability of rolling a sum of 14 is [tex]\frac{1}{72}[/tex] or 0.014.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Formula of probability
Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]
According to the question
rolling a sum of 14
As the maximum sum of two dice is 6+6 = 12
Therefore ,
we will take 3 dices
Now ,
As each dice have 6 different digits and can be repeated
i.e
Total outcomes = 6 * 6 * 6 = 216
Favorable outcome :
(6,6,2) or (2,6,6) or (6,2,6) = 3 ways
Now,
By using the formula of probability
Probability(Event) = [tex]\frac{Favorable Outcomes}{Total Outcomes}[/tex]
Substituting the value in the formula
Probability(Event) = [tex]\frac{3}{216}[/tex]
Probability(Event) = [tex]\frac{1}{72}[/tex] or 0.014
Hence, the probability of rolling a sum of 14 is [tex]\frac{1}{72}[/tex] or 0.014

The manager of a computer retails store is concerned that his suppliers have been giving him laptop computers with lower than average quality. His research shows that replacement times for the model laptop of concern are normally distributed with a mean of 4.2 years and a standard deviation of 0.6 years. He then randomly selects records on 38 laptops sold in the past and finds that the mean replacement time is 3.9 years. Assuming that the laptop replacement times have a mean of 4.2 years and a standard deviation of 0.6 years, find the probability that 38 randomly selected laptops will have a mean replacement time of 3.9 years or less.
Answer: 0.0010
Step-by-step explanation:
Given the following :
Population Mean(m) = 4.2 years
Sample mean (s) = 3.9
Standard deviation (sd) = 0.6
Number of samples (n) = 38
Calculate the test statistic (z) :
(sample mean - population mean) / (sd / √n)
Z = (3.9 - 4.2) / (0.6 / √38)
Z = (- 0.3) / (0.6 / 6.1644140)
Z = -0.3 / 0.0973328
Z = - 3.0822086
Z = - 3.08
From the z table :
P(Z ≤ - 3.08) = 0.0010
Which two hundred thousands is 185,104 between
Answer:
100,000 and 200,000
Step-by-step explanation:
If I understand correctly, I'm guessing you mean which 100,000s(ex.100,000) so it would be between 100,000 and 200,000
185,104 is between 100,000 and 200,000.
The hundred thousands are:
100,000 , 200,000 , 300,000 , 400,000 all the way up to 900,000The number 185,104 is higher than the first 100,000.
It is however less than 200,000.
We can therefore say that 185,104 is between 100,000 and 200,000.

Answer:
A. x = 5 or 7
B. these are zeros of the quadratic
Step-by-step explanation:
A) To factor this equation, we look for factors of +35 that have a total of -12. We know that ...
35 = (-1)(-35) = (-5)(-7)
The latter factor pair has a total of -12, so we can use those in the binomial factors:
(x -5)(x -7) = 0
The solutions are the values of x that make these factors be zero:
x = 5 or x = 7
__
B) The graph of the quadratic on the left of the equal sign is shown in the attachment. The solution values are the values of x where that graph crosses the x-axis, where the quadratic is equal to 0. This should come as no surprise, since we're solving the equation x^2 -12x +35 = 0.

Callen knows that the area of square piece of artwork he owns is 289 square inches. Which shows the correct step he should take if he wants to find out the side lengths of the piece of artwork?
Answer:
D
Step-by-step explanation:
The formula for the area of a square is:
[tex]A=s^2[/tex]
Where A is the area and s is the side length.
We already know that the area is 289 square inches. So, substitute 289 for A:
[tex]289=s^2[/tex]
So, to find s, our side length, let's take the square root of both sides:
[tex]s=\sqrt{289}[/tex]
So, our answer would be D.
And we're done!
Further notes: Each side length will be √289 or 17 inches.

D

8. What is the solution to the equation 3x + 5(4x-6)-8= 3x - 14? a. x = 1 b. r = 1.7 d. There are no solutions to this equation.
3x+5(4x-6)-8=3x-14
Step-by-step explanation:
Cancel out the terms on both sides of the equation. (3x)
5(4x-6)-8=-14
Distribute 5 through the parentheses.
20x-30-8=-14
Calculate the difference.
20x-38=-14
Move the constant to the right-hand side and change its sign.
20x=-14+28
Calculate the sum.
20x=24
Divide both sides of the equation by 20.

The sizes and sale prices for six homes are given in the table. Which coefficient is the only realistic value for the correlation between the sizes of these homes and sale prices
Answer:
the answer is -0.018
Step-by-step explanation:
i asked the same question
The only realistic coefficient value for the correlation between the sizes of these homes and sale prices is 0.981
How to determine the coefficient?The table of values is given as;
x : 1200 1350 1720 1510 1440 1675
y : 223 298 427 375 310 402
To calculate the coefficient, we make use of a graphing tool with the following summary:
X Values
∑ = 8895Mean = 1482.5∑(X - Mx)2 = SSx = 193387.5Y Values
∑ = 2035Mean = 339.167∑(Y - My)2 = SSy = 28986.833X and Y Combined
N = 6∑(X - Mx)(Y - My) = 73452.5R Calculation
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = 73452.5 / √((193387.5)(28986.833))
r = 0.9811
Approximate
r = 0.981
