Answer:
Step-by-step explanation:
Let 'D' be the distance between Cleveland and St. Louis.
Given:
'd' is the distance between St. Louis and Chicago.
The distance between Cleveland and St. Louis is 3 miles less than 2 times the distance between St. Louis and Chicago. This means,
The distance 'D' is 3 miles less than 2 times the distance 'd'.
Now, framing in equation form we get:
2 times 'd' means multiplying 2 to 'd'. This gives
Now, 3 miles less than means subtracting 3 from
. This gives,
Therefore, the distance between Cleveland and St. Louis is given as:
The equation is y = 2x - 12
<h2>Explanation</h2>Equation in slope intercept form is
Where,
m = slope
b = y-intercept
Putting the value of slope in this equation:
From this we can solve the equation for b
Now, the equation of y-intercept becomes
Answer:
False
Step-by-step explanation:
Let p1 be the population proportion for the first population
and p2 be the population proportion for the second population
Then
p1 = p2
p1 ≠ p2
Test statistic can be found usin the equation:
where
As |p1-p2| gets smaller, the value of the <em>test statistic</em> gets smaller. Thus the probability of its being extreme gets smaller. This means its p-value gets higher.
As the<em> p-value</em> gets higher, the null hypothesis is less likely be rejected.
