What is the expected value?In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.
The expected value is given below.
E(x) = np
Where n is the number of samples and p is the probability.
For the true or false, the probability of getting correct is given as,
p = 1/2
There are 570 true or false questions in a quiz. If the pupil guesses for each inquiry. Then the expected value is given as,

What is the value of n??
9514 1404 393
Answer:
73.6°
Step-by-step explanation:
The whole is the sum of the parts:
n = 44.5° +29.1°
n = 73.6°
Answer and Step-by-step explanation:
To find the value of n, we must add the two given angles first.
Why?
We add these two angles together because we are shown that angle n encompasses both angles, meaning that the value of n must be the combination of the angles added together.
29.1 + 44.5 = n
Add.
73.6° = n
The value of n is 73.6°.

Carmen made $192 for 12 hours of work.
At the same rate, how many hours would she have to work to make $128?
Answer:
= 12 miles per hour
Step-by-step explanation:
This is a fraction equal to
30 miles ÷ 2.5 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2.5
30 miles ÷ 2.5
2.5 hours ÷ 2.5
=
12 miles
1 hour
=
12 miles

What is the gross earnings for a person who has $26,480 in total sales,
$1250 in Returns and Allowances, and a rate of commission of 7%?
Answer:
$3103.6
Step-by-step explanation:
Given data
Total sales= $26,480
Returns and Allowances=$1250
Commission = 7%
Let us find the amount in commission earned
=7/100*26,480
=0.07*26480
=$1853.6
Hence the gross earnings
=1853.6+1250
=$3103.6

Juan has four ties, three shirts and four pairs of pants. How many different outfits can he wear if he chooses one Tie, one shirt, one pair of pants of each outfit?
Answer:
48 outfits
Step-by-step explanation:
Using Fundamental Principal of counting
number of outfits that Juan can wear
=number of ties * number of pants * numberof pants
=4*3*4
=48 outfits
The number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.
What is the combination?The arrangement of different things or numbers in a number of ways is called a combination.
A permutation is an orderly arrangement of things or numbers. Combinations are a way to choose items or numbers from a collection or group of items without worrying about the items' chronological order.
Given that Juan has four ties, three shirts, and four pairs of pants.
Using the Fundamental Principle of counting,
Number of outfits that Juan can wear
N =number of ties x number of pants x number of pants
N =4 x 3 x 4
N =48 outfits
Therefore, the number of different outfits can he wear if he chooses one Tie, one shirt, one pair of pants for each outfit is 48 outfits.

The admission prices for a small fair are $1.50 for children and $4.00 for adults. In one day there was $5050 collected. If we know that 2100 children paid admission, find the number of adults that paid admission.
Answer: 475 adults paid admission
Step-by-step explanation:
1.50c+4a=5050 (1.50 per child and 4 per adult)
1.50(2100)+4c=5050 (2100 children times 1.5 each)
3130+4a=5050

D
Answer:
53.1
Step-by-step explanation:
They're equal, so 8 = 31 and 13.7 = x
8/31 = 13.7/x
31(13.7) / 8 = 53.0875
Round your answer to nearest tenth to get 53.1
The rounded length of DE is 53.1.
What is similar triangles?
Similar triangles are triangles that have the same shape, but their sizes may vary.
What is the measure of DE?The both the triangles are similar, so the side length CB will be equal to FE and the side length AB will be equal to DE. Hence, the equation formed will be,
[tex]\frac{8}{31}=\frac{13.7}{DE}[/tex]
On solving this equation, we have DE=53.0875.
Therefore, the rounded length of DE is 53.1.

The difference between two numbers is 7. The sum of twice the larger number and three times the smaller number is 19.
Answer:
x= 8 y= 1
Step-by-step explanation:
First, you identify your variables:
x= larger number
y= smaller number
Second, you find your equations:
x - y = 7
2x + 3y = 19
Third, (I used the substitution method) you make "y" by itself for the 1st equation.
y = x - 7
2x + 3y = 19
Then, you plug in the 1st equation for "y" in the 2nd equation
2x + 3(x - 7) = 19
Then, you distribute and simplify.
2x + 3x - 21 = 19
5x - 21 = 19
5x = 40
x = 8
Finally, you plug in the variable you found ( x ) into one of the equations and solve,
8 - y = 7
- y = -1
y = 1
