Answer: m=-3/2
Step-by-step explanation: Rise/Run
Rise is 3
Run is -2
So it would be -3/2
Answer:
g(7) = -34/13
Step-by-step explanation:
In order to find g(7), we first need to find the g(x) function. To do so, use the two ordered pairs given, (-3, 2) and (10, -4). First we find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - -4)/(-3 - 10)
m = 6/-13
Now that we have the slope, we can use that and either ordered pair in point-slope form to get the equation of the function.
y - y1 = m(x - x1)
y - 2 = 6/13(x + 3)
y - 2 = -6/13x - 18/13
y = -6/13x + 8/13
g(x) = 6/13x + 8/13
Now that we have this, we can plug in 7 for x and find g(7).
g(x) = -6/13x + 8/13
g(7) = -6/13(7) + 8/13
g(7) = -42/13 + 8/13
g(7) = -34/13
Answer:
32 days must be sampled to test the proposed hypothesis.
Step-by-step explanation:
Consider the provided information.
The average number of person-hours per day spent on these task was 
.
The actual value of μ is 12 hours or less i.e μ=12
She wants a test having α=0.05
The probability of a type II error of at most β=0.10 and σ=7.64.
δ = μ-μ0
= 12-16
= -4
Now use the formula for calculating the sample size:
Substitute the respective values.
Hence, 32 days must be sampled to test the proposed hypothesis.
This question is a little ambiguously worded, however I assume the answer would simply be:
$500 - $112 - $28 = the amount he has left.
Hope this helped :))
