1. the mean is 16
2. the mean is 22.5
the formula that can be used to calculate the mean is
= sum of terms/number of terms
for the first question the mean can be calculated as follows
sum of terms= 20+15+19+16+10
= 80
number of terms= 5
mean= 80/5
= 16
for the second question the mean can be calculated as follows
sum of terms= 19+23+11+30+27+27+22+26+16+24
= 225
number of terms= 10
mean= 225/10
= 22.5
Hence the mean for the first expression is 16 and the mean for the second expression is 22.5

Anything that has 1 has x + is A positive number for any purpose of the equation
Answer:
If you're rounding to the nearest two decimal places it's 12.65
Step-by-step explanation:
Pythagorean Theorem :)
12^2 + 4^2 = b^2
144+16= 160
The square root of 160 is about 12.65
Answer:
10i
Step-by-step explanation:
√-100 = √-1 × √100 = i × 10 = 10i
I don't understand why there are two boxes though.
Answer is :Y is the easiest first using second equation . Ill show you steps below why . If you want to see the steps .
2x+4y=26
3x+y = 9
So first solve second equation
3x+y=9
Y= -3x+9
Now plug into first equation
2x+4y=26
2x+4(-3x+9)=26
2x-12x+36=26
-10x+36=26
-10x= 26-36
-10x= -10
X=1
So now solve for y in second equation
Y= -3x+9
Y= -3(1)+9
Y= -3+9
Y= 6
So if you were to be asked answer in point (1,6).
