You’re gonna want to start this problem by going to your Calculator and hitting stat and then edit. Once you do that you’re going to want to type in the first column, which is one, two, three etc. Once you’re done with that column, you’re gonna want to hit your right arrow and hit the second column digits into L2. After this, you’re going to go to your stat button switch over to Calc, hit 1 – var stats, and the x with a - above it is the mean.
Step-by-step explanation:
third and the yellow one will be the answer
x=11,X=-1/5
Hi
2/3 y+y-4=31
Simplify both sides of the equation
2/3 y-4=31
Combine like terms
(2/3 y+y)+(-4)=31
5/3 y-4=31
Add 4 to both sides
5/3 y-4+4=31+4
5/3 y=35
Multiply both sides 3/5
(3/5)*(5/3 y)=(3/5)*35
y=21
I hope that's help !
New price = <u>90 dollars</u>
<u></u>
25% of 120 = 30
Price is reduced 25% from 120 so,
120 - 30 = 90
Amount of discount = 30
