Answer:
y = 3x - 5
Step-by-step explanation:
We know that the equation 'y = 3x + ?' intersects the point (1, -2). This means that when x = 1, y = -2 in out equation above. To solve this just plug in the x and y values to get '?'.

Now that we know '?' is -5, we write it back into slope intercept form, so our final answer is y = 3x - 5
Answer:
Option A) reject null hypothesis if z is greater than 1.645
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 250
p = 30% = 0.3
Alpha, α = 0.05
Number of women belonging to union , x = 75
First, we design the null and the alternate hypothesis
This is a one-tailed(right) test.
Rejection Region:

So, the rejection region will be

That is we will reject the null hypothesis if the calculated z-statistic is greater than 1.645
Option A) reject null hypothesis if z is greater than 1.645
Answer:
you will need to wait 3 hours and 30 mins
Step-by-step explanation:
Oh yes, I am very hurrying, yet!
precedence is:
1 Parentheses (simplify inside 'em)
2 Exponents
3 Multiplication and Division (from left to right)
4 Addition and Subtraction (from left to right)
(7+41) = 48
48 ÷ 2 = 24
24 -15 = 9
