c. 70 m3
d.392 m3
Answer:
Step-by-step explanation:
Alright, lets get started.
When we add or subtract any thing from the function f(x), that is called vertical shift.
The vertical shift means graph will move up or down.
When something is added, the graph of f(x) goes up means vertical shift up.
When something is subtracted, the graph of f(x) goes down, means vertical shift down.
So, when 11 is subtracted from f(x), it means, the graph of f(x) will shift 11 units down. : Answer

hides his car on a side street that intersects the middle of the school zone and records the speed of each car that
passes through. The 36 cars that he recorded had an average speed of 16.33 mph with a sample standard deviation
of 2.54 mph.
Calculate the appropriate test statistic (Give as a decimal rounded to the nearest thousandth).
Answer: test statistic = 0.002
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 15
For the alternative hypothesis,
µ > 15
The inequality sign means that it is right tailed.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 36,
Degrees of freedom, df = n - 1 = 36 - 1 = 35
t = (x - µ)/(s/√n)
Where
x = sample mean = 16.33
µ = population mean = 15
s = samples standard deviation = 2.54
t = (16.33 - 15)/(2.54/√36) = 3.14
We would determine the p value using the t test calculator. It becomes
p = 0.002

3x - 12 = 17
7(x + 1) = 14
1- 6x = -11
4x + 5 = 3
Answer: 1 - 6x = -11
Step-by-step explanation:
For each expression, substitute x for 2 to determine which is the correct expression:
3x - 12 = 17
3(2) - 12 = 17
6 - 12 = 17
-6 17
Because the number on the left side of the equation doesn't equal the number on the right, this first equation is incorrect.
7(x + 1) = 14
7(2 + 1) = 14
7(3) = 14
21 14
This second equation is incorrect as well.
1 - 6x = -11
1 - 6(2) = -11
1 - 12 = -11
-11 = -11
Because the number on the left equals the number on the right, the third equation is correct.
I hope this helps! :)
