Answer:
The value of the test statistic is -1.53
Step-by-step explanation:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 96 hours
Sample mean, 
= 95 hours
Sample size, n = 150
Alpha, α = 0.05
Population standard deviation, σ = 8 hours
Formula:
Putting all the values, we have
Thus, the value of the test statistic is -1.53
1) BC intercept y at (2,1) (given)
2) The slope of AB ===> m= (-1 - 1)?(14 - 2) ===> m = - 1/6
2) the slope of BC that is perpendicular to AB is the inverse of (1/6) & change the sign, that is 6. To find the function y, apply the formula:
y-y1) = m(x-x1) ===> y-1 = 6(x-2) [the coordinate of B] ==> y= 12x - 11
3) if y= 13, replace y by 13 in the equation:
13 = 12x -11 ===>x = 2
Answer B as 6 divided by 24 is 4
The answer to the problem is A) 20 feet below sea level
Step-by-step explanation:
the 60 preliminary published articles are a constant.
all the new articles are simply added to that to get the total number of published articles.
every months produces 12 more articles.
so,
m = 1 means a = 60 + 1×12 = 72
m = 3 means a = 60 + 3×12 = 60 + 36 = 96
m = 4 means a = 60 + 4×12 = 60 + 48 = 108
m = 9 means a = 60 + 9×12 = 60 + 108 = 168
