Answer:
Part 3: 9 Dogs
Step-by-step explanation:
It says that the ratio they want you to put it in is dogs/students, so dogs are x, and students are y, so if there are 4 students for every dog, 36 students would require 9 dogs
And if the roles were switched it would be students x, dogs y, and there would be 9 students for 36 dogs :D
Answer:
95% Confidence interval for y
= (-9.804, -5.979)
Lower limit = -9.804
Upper limit = -5.979
Step-by-step explanation:
^y= 2.097x - 0.552
x = -3.5
Standard error = 0.976
Mathematically,
Confidence Interval = (Mean) ± (Margin of error)
Mean = 2.097x - 0.552 = (2.097×-3.5) - 0.552 = - 7.8915
(note that x=-3.5)
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error of the mean)
Critical value for 95% confidence interval = 1.960
Standard Error of the mean = 0.976
95% Confidence Interval = (Mean) ± [(Critical value) × (standard Error of the mean)]
CI = -7.8915 ± (1.960 × 0.976)
CI = -7.8915 ± 1.91296
95% CI = (-9.80446, -5.97854)
95% Confidence interval for y
= (-9.804, -5.979)
Hope this Helps!!!

Answer: 1</h3>
=================================================
Explanation:
The rule is
x^0 = 1
where x is nonzero (ie, not equal to zero). So whatever number you raise to the zeroth power, the answer is always 1.
---------------
Let's see why this rule works
x^1 = x ... raising something to the first power is itself
(x^1)/x = x/x ... divide both sides by x
(x^1)/x = 1 .... turn the 'x/x' into 1
(x^1)/(x^1) = 1 .... rewrite the second 'x' as 'x^1'
x^(1-1) = 1 ... subtract exponents
x^0 = 1
