Answer:
Option C.
Step-by-step explanation:
For a given set of N elements:
{x₁, x₂, ..., xₙ}
The mean is given by:
And the variance is given by:
Then for our set:
{70, 80 ,75, 75, 80}
We have 5 elements, then N = 5
The first thing we need to find is the mean.
Then the variance will be:
The correct option is C, 14.
X(30;0)
y(0;50)
substitue 0 for y and solve for x
substitute 0 in for x and solve for y
Answer:
Step-by-step explanation:
2) Let 't' be the temperature
t < 7
Height be 'h'
h >= 42
Cos be represented by 'c'
c >= 125
3) Distributive property: a*(b +c) =(a*b) + (b*c)
2(5a + 3b) + 5a +2b = 2*5a + 2*3b + 5a + 2b
= 10a + 6b + 5a + 2b
= 10a + 5a + 6b + 2b {Combine like terms}
= 15a + 8b
6y + 2(3x + 5) + 2y + 3 = 6y + 2*3x + 2*5 + 2y + 3
= 6y + 6x + 10 + 2y + 3
= 6y + 2y + 10 +3 + 6x
= 8y + 13 + 6x
It would be 1444
hope this helps
