Got 100% on edge.
Answer:
a) 83
b) mean and mode are both 83
Step-by-step explanation:
a) mean is the average. so add all the numbers and divide by the number of numbers.
<u>88 + 73 + 81 + 83 + 79 + 94 + T</u> = 83
7
b) median - put the numbers in numerical order, smallest to largest, what is the middle number (4th number) 73, 79, 81, 83, 83, 88, 94
mode - which number shows up most frequently?
Answer:
x1=5/2+i
x2=5/2-i
Step-by-step explanation:
x^2-5x+7=0
a=1, b=-5, c=7
x1=(-b+sqrt(b^2-4ac))/2a
x1=(-(-5)+sqrt(5^2 - 4*1*7))/2
x1=(5+sqrt(25-28))/2
x1=(5+sqrt(-4))/2
x1=(5+sqrt(4i^2))/2
x1=(5+2i)/2
x1=5/2+i
x2=(-b-sqrt(b^2-4ac))/2a
x2=(5-2i)/2
x2=5/2-iw
I think it is e because 39 is not even and 48 isnt odd. then a doesn't intersect b when its not 0? I am not sure. But i am pretty sure it is E.
Okay so,
(Heads up! If it’s a number (the one in photo, I don’t know how to type it so imma put a *(number))
3K+2K(5K-3)=7
-
3K+2Kx(5K-3)=7
Multiply parentheses by 2K
-
3K+10K*2-6K=7
Collect the like terms
-
-3K+10K*2=7
Move the constant to the left
-
-3K+10K*2-7=0
Reorder the terms
-
10K*2-3K-7=0
Solve the quadratic equation
