B.0

C.6

D.12

Answers

Answer 1

Answer: $\hbox{reciprocal of } a=(1)/(a)\n a=(1)/(6)\n (1)/(a)=(1)/((1)/(6))=1\cdot6=6 \Rightarrow C$

Answer 2

Answer: reciprocal is where you flip the fraction so 1/6 becomes 6/1
C. 6

$\sqrt{200 {x}^2 {y}^2 {z}^2$

Answers

For number 30, its easier if its broken down so were going to make it √200*x^2*y^2*z^2. We can't get a square root of 200 so we will break it into 100*2 to get √2*100*x^2*y^2*z^2. Now let's look at what we can take the square roots of. 2 doesn't have a nice sq. rt. so we will leave it there. 100 has the rt. of 10 so we can make 10√2*x^2*y^2*z^2. X^2 has the root x and we can follow this with the other variables to get 10xyz√2. There is your final simplified answer.

Roots have a property which allows for separation of terms based on wether they are being multiplies:
100*2*x^2...
10xyz * \/2

A secret code is designed by choosing a letter from the alphabet and then choosing a digit from 0-9. which equation below correctly represents the probability of choosing the secret code “7Q” according to the picture?

Answers

This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture. Thus, option (D) is correct.

Event - 1: Choosing a letter from the alphabet that is Q.

Let us assume the probability of happening of event 1 is P(Q).

Event - 2: Choosing a digit from 0-9 that is 7.

Let us assume the probability of happening of event 1 is P(7).

Now, we need to choosing the secret code that is 7Q.

We need to multiply both events to get the desired result.

Thus,

$P(7 \cap Q)=P(7) * P(Q)$

This is the only option that correctly represents the probability of choosing the secret code “7Q” according to the picture.

Answer:

Option 4: P(7∩Q) = P(7) × P(Q)

Step-by-step explanation:

P(7∩Q) represents the probability of choosing the secret code "7Q".

If A and B are independent events, then,

P(A∩B) = P(A) × P(B)

Let A be the event of choosing a number from 0-9 and

B be the event of choosing an alphabet.

Clearly, A and B are independent.

Therefore,

P(7∩Q) = P(7) × P(Q)

In a school of 260 children, 55% are girls. How many girls are there? At the same school, 10% of children leave for a school trip. How many pupils go on the trip?

Answers

Number of children in a school = 260
Percentage of girls in the school = 55%
Number of girls in the school = (55/100) * 260
      = 14300/100
   = 143
So there were 143 girls in the school among 260 children
Percentage of children going for the school trip = 10%
Then
Number of students going for the school trip = (10/100) * 260
      = 26
So 26 children are going for the school trip. I hope the procedure is clear enough for you to face similar problems in future.

260 children* (55/100)= 143 students.
There are 143 girls~

260 children* (10/100)= 26 students.
26 students go on the trip~

Hope this helps~

What is 276% of 8 in fraction form?

Answers

To find a percentage of a number, you just need to multiply the percentage by that number.

Percentages must be converted into decimal form before any work can take place. We can do that by either dividing the percentage by 100, or (my personal shortcut) by just shifting the decimal point to the left two places.

276% = 2.76

Then, we just need to multiply.

2.76 * 8 = 22.08

Since the question requires the answer in fraction form, we need to convert 22.08 to a mixed number. This mixed number would be 22 2/25

276% of 8 in fraction form is 22 and 2/25.
Hope this helped =)

276% of 8 in fraction form is 22.08 because
2.76 * 8 = 22.08
