[Grade 7 maths]
I really hope I’m correct saying y squared + y is equal to y(2y)

No, it is equal to y² + y

Step-by-step explanation:

No, you are incorrect.

Lets break it down.

Y squared means y to the power of two, which looks like this:

y²

Then, you have to add a y, so the end result should look like this:

y² + y

step-by-step explanation:

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
