Answer:
y=4
Step-by-step explanation:
A line that is parallel to the x-axis would have an equation of y= ______.
This is because a horizontal graph has a gradient of zero, thus the value of m in y=mx+c is zero.
y=0x +c
y= c
Since it passed through the point (1,4):
When x=1, y=4,
4= 0(1) +c
c= 4
Thus, the equation of the line is y=4.
(1, 8) and (7,1)
slope = (8-1)/(1-7) = -7/6
y = mx + b
b = y - mx
b = 8 - (-7/6)(1)
b = 8 + 7/6
b = 55/6
equation
y = -7/6(x) + 55/6
answer
<span>y=−7/6 x+55/6 </span>
The answer is 35/2 (fraction)

Answer:
Stratified sampling
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Population divided into groups, and random samples are drawn from the groups. This is a mark of stratified sampling.
