I'm her first quiz she did better, this is going to be hard to explain but pay attention 92% as a decimal is 92/100 keep this in mind, then 27 out of 30 question we try to make 30 go into 100 but we know 30 can't go into 100 without a decimal so what we do is we change the decimal to 90 so for the 27 out of 30 it is now 81/90, now we need to change the denominator in 92/100 to 90 so we subtract 10 from the numerator and denominator to get 82/100 so compare the 2 decimals you got 81/90 and 82/90 and you find that 82/90 is bigger so she did better on the first quiz
Step-by-step explanation:
given x=2
and the equation

to find the value of q , you need to make q the subject in the equation as shown below
q= 3x-x -4
q=2x-4
but x= 2
so just substitute the value of x in the equation for the q

q=4-4
q=0
therefore the value of q is 0

this is my answer...sorry if I made any mistake
The mean you have to add up your numbers first then divide them by the amount of numbers you have .ex. 1+2+3 is 6 then divide so 6÷3 =3
Median is the middle number in list. So put them in order then muddle number is your median. If you have two numbers left add them and divide by 2. That will be your median.
