For a line in the form:
In this case, for the line 2x + 10y = 20 with a=2 and b=10 the slope is:
Now, two lines are perpendiculars if the slopes satisfy the following equation:
So, for the line we want the slope is:
Finally, the line pass througth the point (2, 3) with slope m=5, so the equation is:
The equation of the line is y = 5x - 7

Answer:
Two independent sample t test
Step-by-step explanation:
The research described describes the statistics of two different samples which are also independent,
Sample 1 :
Sample size, n1 = 16
Mean, xbar = 4.75
Standard deviation s2 = 2.8
Sample 1 :
Sample size, n1 = 15
Mean, xbar = 3.93
Standard deviation s2 = 2.4
The hypothesis :
H0 : μ1 = μ2
H1 : μ1 ≠ μ2
The t statistic :
(xbar1 - xbar 2) ÷ sqrt[(s1²/n1 + s2²/n2)
From on the test statistic, obtain the p value and compare with Given α - value to make and conclude in a decision.
Answer:
idk how to divide power of ten but u know by the number beside it if it said the power of 10(2) then u do 10x10 dont do 10x2. all u need to do is just add the amont of zeros to the ten
