Mathematics

Remember: when calculating percent it will always be over 100. With the given numbers 14 is your part out of the total (25). It should be written as part/whole.

As previously said, the percent is always over 100. (x/100)

In this problem you are given the part (14) and the whole (25). So it would be 14/25. The percent in this problem would be x/100. Now to find percent with the given part/whole, you would multiply 14 with 100. Then simply divide by 25.

A first number plus twice a second number is 13 Twice the first number plus the second totals 35 Find the numbers.
Sophie [7]

Answer:  the first number is 19 and second number is -3

Step-by-step explanation:

Let the First number be represented as  x

and  second number be represented as  y

Therefore, A first number plus twice a second number is 13 be expressed as

x + 2y = 13-----equation 1

also  Twice the first number plus the second totals 35

2x+ y = 35---- equaton 2

Step 2 --- Solving

x + 2y = 13-----equation 1

2x+ y = 35---- equation 2

By substitution, making x subject of formulae in equation 1

x+ 2y = 13

x= 13 - 2y

putting the value of x= 13- 2y in equation 2

2( 13 - 2y) + y= 35

26 - 4y + y= 35

-4y + y= 35- 26

-3y= 9

y = 9/-3

y= -3

To Find x , using equation 1

x + 2y = 13

x+ 2 x -3= 13

x-6=13

x= 13+6

x= 19

Therefore the first number = 19 and the second number = -3

Garrett gets 36 problems right.

Step-by-step explanation:

Given that,

Total number of MCQs = 60

Correct answers = 60%

We need to find how many problems did Garrett get right. It can be calculated by finding 60% of 60 such that,

C=\dfrac{60}{100}\times 60\\\\=36

So, Garrett gets 36 problems right.

Arte-miy333 [17]
A.) Probability of selecting two students and two faculty members from 20 students and 5 faculty volunteers = no of ways of selecting two students and two faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C2 x 5C2) / 25C5 = 1900 / 53130 = 0.036 = 3.58%

b.) Probability of selecting three students and one faculty members from 20 students and 5 faculty volunteers = no of ways of selecting three students and one faculty members from 20 students and 5 faculty volunteers divided by the number of ways of selecting 4 people from 25 people = (20C3 x 5C1) / 25C5 = 5700 / 53130 = 0.107 = 10.7%
