y - y₁ = m(x - x₁)
y - (-2) = ¹/₂(x - 4)
y + 2 = ¹/₂(x) - ¹/₂(4)
y + 2 = ¹/₂x - 2
- 2 - 2
y = ¹/₂x - 4
Use the proportion formula:
5mm/32= Xmm/160
=22.22 mm
If the number of samples is increased, this actually leads
to a reduction in error of the distribution. This is because of the
relationship between variation and sample size which has the formula of:
σx = σ / sqrt (n)
So from the formula we can actually see that the variation
and sample size is inversely proportional.
Which means that increasing the sample size results in a
reduction of variation.
Answer:
It will have less variation
Median: The middle number in the data set when the
data set is written from least to greatest.
Since our data set is already written from least to greatest,
we can just look for the number that appears in the middle.
In this case, it would be 3.
Mode: The number that appears
most frequently in a data set.
Notice that the number 3 appears twice in the data set and no other
number appears more than once. So the mode is 3.
Range: The difference between the greatest number in
the data set and the least number in the data set.
Since the greatest number is 8 and the least number is 1,
the range of the data set will be 8 - 1 or 7.
Answer:
4.75x + 14.40y ≥ 700
Step-by-step explanation:
Given:
Plant cost = $4.75
Shrub cost = $14.40
Number of plant = 80
Number of shrub = 25
Total cost = $700
Find:
Inequality
Computation:
Number of plant = x
Number of shrub = y
4.75x + 14.40y ≥ 700
