Answer:As the sample size increases, the impact of the misrecorded data on the mean decreases.
Step-by-step explanation:
The size of an experiment is very important in a research. Large experimental size with many sample unit helps to minimize error this is because the error is shared among all the samples but when an experimental unit is small the error is usually high.
As sample sizes increases the number of misrecorded data on the mean decreases this is because error is usually spread across all samples in a large sample size and the mean is the average performance of the samples.
Answer:
The X axis
Step-by-step explanation:
Don't report what you don't understand
the x value of the vertex of the parabola in form
y=ax^2+bx+c
is -b/2a
given
y=6x^2-72x+220
x value of vertex is -(-72)/(2*6)=72/12=6
xvalue is 6
sub that for x in the equation
y=6(6)^2-72(6)+220
y=216-432+220
y=4
(x,y)
vertex is (6,4)
Answer:
d.
Step-by-step explanation:
1) to re-write the given equation from 2y=4x-6 into y=2x-3, then
2) to find the equation like y=2x±... among the a/b/c/d: it is d. y=2x+14. Then
3) to check the given point (-3;8) of the y=2x+14; ⇒ 8=8.
4) correct answer is d. y=2x+14.
