The table below shows the probability distribution of student ages in a high school with 1500 students. What is the expected value for the age of a randomly chosen student? Age 13 14 15 16 17 18 Probability 0.01 0.27 0.30 0.25 0.16 0.01 O A. 15.38 OB. 15.31 O C. 15.50 D. 15.35 SUBNET
Answer:
According to me it should be Option B, 15.31
Hope this helps!
The expected value for the age of a randomly chosen student is,
⇒ 15.38
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that:
Total number of students,
⇒ n = 1500,
And, Age : 13, 14, 15, 16, 17, 18
Probability : 0.01, 0.25, 0.27, 0.30, 0.16, 0.01
Now,
We can Calculate the expected value as shown below,
E = 13 × 0.01 + 14 × 0.25 + 15 × 0.27 + 16 × 0.30 + 17 × 0.16 + 18 × 0.01
E = 0.13 + 3.5 + 4.05 + 4.8 + 2. 72 + 0.18
E = 15.38
Therefore, The expected value for the age of a randomly chosen student is 15.

A teacher assigns 10 questions for homework and wants to randomly pick 3 questions to be graded. He writes the numbers 1–10 on equally sized slips of paper and places them in a bag. He shakes the bag and selects 3 slips of paper. Is the sample of 3 questions a simple random sample? Yes, because the paper slips were equally sized. Yes, because the paper slips were equally sized and the bag was shaken. No, because there are only 10 questions. No, because the questions were selected using a bag.

Answer:
8. A = {Delaware, New Jersey, Pennsylvania}
9. |B| = 3
Step-by-step explanation:
8. Dates prior to 1 Jan 1788 are those in 1787. The three states admitted in 1787 are listed as Delaware, Pennsylvania, New Jersey. It is usually convenient to list elements of a set in lexicographical order:
A = {Delaware, New Jersey, Pennsylvania}

Which equation has the following: Center (0, -3) and radius [tex]\sqrt{11}[/tex]
Answer:
The equation of the circle is [tex]x^2 + (y + 3)^2 = 11[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Center (0, -3)
This means that [tex]x_0 = 0, y_0 = -3[/tex]
Radius square root of 11
This means that [tex]r = \sqrt{11}[/tex]
Equation of the circle:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - 0)^2 + (y - (-3))^2 = (\sqrt{11})^2[/tex]
[tex]x^2 + (y + 3)^2 = 11[/tex]
The equation of the circle is [tex]x^2 + (y + 3)^2 = 11[/tex]

The amount of water dispensed by a water dispenser is normally distributed,
with a mean of 12.10 ounces and a standard deviation of 0.25 ounces. In
which range will the amount of water dispensed be found 95% of the time?
A. 11.85 ounces to 12.35 ounces
B. 11.35 ounces to 12.85 ounces
C. 11.60 ounces to 12.60 ounces
D. 11.10 ounces to 13.10 ounces
Answer:
C. 11.60 ounces to 12.60 ounces
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean 12.10, standard deviation 0.25.
In which range will the amount of water dispensed be found 95% of the time?
By the Empirical Rule, within 2 standard deviations of the mean. So
12.10 - 2*0.25 = 12.10 - 0.5 = 11.60
12.10 + 2*0.25 = 12.10 + 0.5 = 12.6
So the correct answer is given by option C.

A 12.5 oz bag of Doritos costs $3.79. A 3 oz bag costs $1.00. What is the difference in unit rates?
Answer:
0
Step-by-step explanation:
12.5/3.79 = 3.2981530343
3.2981530343 rounded = 3.3
1/3 = 3.33333333333333
3.33333333333333 rounded = 3.3
3.3 - 3.3 = 0
9514 1404 393
Answer:
$0.03 per ounce
Step-by-step explanation:
The unit rate for the smaller bag is ...
$1.00/(3 oz) = $0.333 /oz
For the larger bag, it is ...
$3.79/(12.5 oz) = $0.303 /oz
Then the difference in unit rates is ...
$0.333 -0.303 = $0.03 . . . per ounce
I am thinking of a number.i add 62 to the number and divide the total by 7.the result is 4 less than the number 1 thought of.what was the number
Answer:
15
Step-by-step explanation:
let the number be n, then
[tex]\frac{n+62}{7}[/tex] = n - 4 ( multiply both sides by 7 to clear the fraction )
n + 62 = 7n - 28 ( subtract n from both sides )
62 = 6n - 28 ( add 28 to both sides )
90 = 6n ( divide both sides by 6 )
15 = n
That is the number is 15
If AABC ~ ADEF, what is the length of DE?
NEED HELP ASAP please and thanks In advance
Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21

Red=40%
Green =x%
40/100 × 60apples
0.4×60
24red apples
so 60-24
36green apples
Answer:
b) 36.
Step-by-step explanation:
Justicemoya35 has an excellent answer, but I will provide a slightly different approach!
According to the word problem, the box contains 60 apples.
If 40% of the apples are red, then 60% of the apples are green.
As I mentioned before, there are 60 apples; 60% of the 60 apples are green.
This means we have the find 60% of 60.
We can find the percentage of a number by using this formula:
60% OF 60
[tex]\frac{is}{of} =\frac{percent}{100}[/tex]
[tex]\frac{x}{60} =\frac{60}{100}[/tex]
Now that I've correctly set up the problem, we cross multiply, then divide the products.
[tex]60*60=3600[/tex]
[tex]100*x=100x[/tex]
[tex]3600/100x=36[/tex]
[tex]x=36.[/tex]
Therefore, 36 apples are red.
