Not gonna give an answer, sorry. Instead, I'll show you a similar example so you can be able to solve it.
An average test score is the sum of all the scores on an assessment divided by the number of test-takers.
For example, if three students took a test and received scores of 69, 87, and 92.
These numbers would be added together and then divided by three to get an average of 82.6.
I hope you know what to do now.
Answer:
Step-by-step explanation:
(82 + 95 + 90 + 87 + x) / 5 = 95 Add like terms on the left
(354 + x) / 5 = 95 Multiply by 5
354 + x = 95 * 5
354 + x = 475 Subtract 354 from both sides
x = 475 - 354
x = 121
On the first step, you need to add an x which represents the score he needs. You divide by 5 because that's how many scores there and and the 5 gives you an average.
Can anyone tell me what the answer to this problem is and the explination?
The figure shown above is triangle. The area of the triangle is a= 1/2base times height.
Base is 10 . The height is 6.
A= 1/2bh
A= 1/2*10*6
A= 1/2*60
A= 30
Or you can find the area of the triangle separately and add them up.
First triangle :
The half of the base is 10/2= 5
B= 5 H= 6
A= 1/2*6*5
A= 15
Second triangle :
b= 5
h= 6
a= 1/2*5*6
a= 15
Add up them both areas 15+15= 30

Answer:
Hello! answer: 35
Step-by-step explanation:
If they can hold 40 on each shelve we can do 40 × 3 and 40 × 3 = 120 then just subtract by 85 to find how many the shelves can hold! So 120 - 85 = 35 so 35 is the answer Hope that helps!

In southern California, a growing number of individuals pursuing teaching credentials are choosing paid internships over traditional student teaching programs. A group of eleven candidates for five local teaching positions consisted of six who had enrolled in paid internships and five who enrolled in traditional student teaching programs. All eleven candidates appear to be equally qualified, so five are randomly selected to fill the open positions. Let Y be the number of internship trained candidates who are hired. (a) Does Y have a binomial or hypergeometric distribution
Answer:
Candidates are chosen without replacement, thus trials are dependent, meaning that Y has a hypergeometric distribution.
Step-by-step explanation:
Difference between hypergeometric and binomial distributions:
In the hypergeometric distribution, trials are dependent of other trials, while in the binomial distribution, they are independent. This can be examplified that in the hypergeometric distribution, the candidates are chosen from a set without replacement, while in the binomial distribution they are chosen with replacement.
In this question:
Candidates are chosen without replacement, thus trials are dependent, meaning that Y has a hypergeometric distribution.

A tray contains 16 chocolate chip cookies and 12 oatmeal raisin cookies. HOw many ways can a child select 3 cookies that include at least 1 chocolate chip cookie
Answer:
Number of ways chosen cookies = 8 ways
Step-by-step explanation:
Given;
Total number of chocolate chip cookies = 16
Total number of oatmeal raisin cookies = 12
Total number of cookies choose = 3
At least 1 chocolate cookie
Find:
Number of ways chosen cookies
Computation;
Number of total ways = 2³
Number of total ways = 8
If at least on cookie is chocolate cookie,
Number of ways chosen cookies = Number of total ways - 1
Number of ways chosen cookies = 9 - 1
Number of ways chosen cookies = 8 ways

x + 2/3 x = 180°
1 2/3x = 180°
5/3 x = 180°
180 * x = 540
540 / 5 = 108
x = 108°

25. Leena and Ricky went for jogging in the morning. Leena ran 2/3 of the track and Ricky ran 5/6 of
the same track. Who ran more and by how much?
Answer:
Ricky ran 16.66% more of the track than Leena
Step-by-step explanation:
First, we find how much each ran as a percentage.
Leena ran 2/3 of the track
As a percentage, Leena ran:
2*100%/3 = 66.67%.
Ricky ran 5/6 of the same track.
As a percentage, Ricky ran:
5*100%/6 = 8333%
Thus Rick ran more, by 83.33% - 66.67% = 16.66%.

if two angles in a triangle are 60° and 30°, is the third angle acute, obtuse, or right?
Answer: Right Angle
Step-by-step explanation:
And Since The Angles Of a Trangle Add Up To 180° When You Substract 90 From It You Remain With Another 90° Which Means The Angle Is Non Other Than a right angle traingle
60° + 30° = 90°
180° - 90° = 90°
∴ 90° = Right Angle Traingle
