In an examination, 80% of candidates passed in English, and 85% passed in Math. If 73% of
candidates passed in both subjects, then what percent of candidates failed in both subjects?
a. 27
X
b. 15
C. 8
d. 35​

Answers

Answer 1

Answer:

8%

Step-by-step explanation:

Using set notation

M is mathematics

E is English

n(M) = 85%

n(E) = 80%

n(M n E) = 73%

n(M U E)'  are percentage of people that failed both subnets

Hence n(U) = n(M U E) + n(M U E)'

n(MUE) = n(M) + n(E) - n(MuE)

n(MUE) = 85 + 80 - 73

n(MUE) = 92%

Since n(U) = n(M U E) + n(M U E)'

100 = 92 + n(M U E)'

n(M U E)'  = 100 - 92

n(M U E)' = 8%

Hence 8% of candidates failed in both subjects

Answers

Answer:

93°

Step-by-step explanation:

By exterior angle theorem:

(4x + 9)° = 2x° + (3x - 12)°

(4x + 9)° = (2x + 3x - 12)°

(4x + 9)° = (5x - 12)°

4x + 9 = 5x - 12

4x - 5x = - 12 - 9

-x = - 21

x = 21

Measure of exterior angle

= (4x + 9)°

= (4*21 + 9)°

= (84 + 9)°

= 93°

hat is the surface area of a cylinder that has a volume if 785.4in3 and a radius of 5 in?


A 471.2in2
B 10in2
C 150in2
D 4712.3in2

Answers

Answer:

A. 471.2 in²

Step-by-step explanation:

Cylinder volume:

V = πr²h

Cylinder surface area:

A = 2πr(r + h)

Find h from the first equation:

h = V/(πr²) = 785.4/(3.14*5²) = 10 in

Find surface area:

A = 2π(5)(5 + 10) = 471.23 in²

Correct choice is A

Answer:

volume of cylinder=πr²h

785.4=22/7×5²×h

h=785.4×7/(22×25)=9.99=10in

Step-by-step explanation:

surface area of cylinder =2πr(r+h)=2π×5(5+10)=

471.238898038in²

A 471.2in2 is your answer.

Kayla studied data collected on the school basketball team for one season. She noticed that a player on the team had 13 successful free throws out of a total of 20 attempted free throws. What percent is that?

Answers

If she is setting up a proportion to find the percent, the value of m would be any variable and the value of n would be 100.  When she solves the problem, m=65%.

13/20 is part out of whole.  The rest of the proportion will be "percent out of 100"; since we don't initially know the percent, we use a variable.  Thus we have

13/20 = m/100

Cross multiply:

20*x = 13*100

20x = 1300

Divide both sides by 20:

20x/20 = 1300/20

x = 65

The angles are adjacent because they are next to each other adding to 90 degrees.

How do we find x?

Angle 1 + Angle 2 = 90°

31° + (10x - 1)° = 90°

10x + 30 = 90°

10x = 90° - 30

10x = 60°

x = 60°/10

x = 6

C is the correct answer.

Step-by-step explanation:

first look at the first "kite". You got to times 30.5 x 4 ,since all of the sides are equal to each other. If you do the you will get (122).

Now onto the next one. you got to do the same but instead you got to times 40.75 x 2, and you'll come up with (81.5). Then you need to take the other number and do the same. 20.25 x 2, and that will equal to (40.5).

When you get those numbers you need to add them. So, 81.5 + 40.5= 122.

In the end you'll end up with C.

Four more than the product of 2 and a

Answers

Four more than the product of 2 and a:

4+2a

Answer:

2a + 4

Step-by-step explanation:

The key word, "product," means you're multiplying, and since it says the "product of 2 and a," you're multiplying 2 and a. To simplify that, you can write 2a (which is equal to 2 · a).

Since it says four more (key word is more), you need to add four to 2a. Since if you have "less than" or "more than", the product will be before the number we're adding, leaving you with  2a + 4.
