Answer:
-5,5
Step-by-step explanation:
(2x+5)( 2x-5) x-5=0 x+5=0 I think that's what you do not sure
F(x) = -3x - 2
f(-5) = -3(-5) -2 = 15 - 2 = 13
Well (x+5)(×-6)
x*x =x2
x*-6=-6x
x*5 = 5x
5*-6= -30
add them all together to get x2-x-30.
I hope this is what you were asking
Answer:
3: No
4: 25
Step-by-step explanation:
3: It won't because not everyone is the same height and there will be variation in the mean height.
4: A larger sample size will give a more accurate representation of the population, where as a sample size of 5 is much more likely to have a higher percentage of outliers, and each outlier matters much more in finding the mean. In a sample size of 25, each outlier matters much less.
