Answer:
Slope: -17/3 Y-intercept: 100
Step-by-step explanation:
I took the test. Hope this helps.
A function associates a value from a set (domain) one and only one value from another set. IE, from the same x value you can have only one y. So pick a ruler and scan each graph parallel to the Y axis. If you touch the blue line in two points, that's not a function.
Let n = required random sample size.
Assume that the population standard deviation is known as σ.
Let m = sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.
Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²
This means that the sample size is about 128 times the population variance.
Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.
287/8.40=34.1666667
34 hours would be too short so you would need to round it up so he would need to work 35 hours but yoh would earn extra money
Answer:
Therefore, option C is correct
Step-by-step explanation:
Budgeted cash receipts for February = 60000 + 303800*0.40 + 274400*.60
= 60000 +121520 + 164640
= 346160
