Answer:
The survey was BIASED and CANNOT be extended to the general population.
Step-by-step explanation:
I took the test bestie.
72, because 360/4 courses = 90 as an average for Adrianna. This means that 360/5 courses equals 72 for roberto.
Answer:
100 texts
Step-by-step explanation:
Let the amount of text messages be x. Since we are looking at making both plans equal, we add the fixed monthly charges to the number of messages multiplied by the cost.
The total amount charged by Totally will be 30 + 0.2x
The total amount charged by Gnarly will be
40 + 0.1x
Now since we are trying to get the number of text messages that make both charges equal, we equate the two charges and that is:
30 + 0.2x = 40 + 0.1x
40 - 30 = 0.2x - 0.1x
0.1x = 10
x = 10/0.1 = 100 texts
Answer:
Step-by-step explanation:
if you modify the parent function to go <u>up and down</u>
for example parent function is y=|x| to go <u>down</u> 3 you do y=|x|-3
if you modify the parent function to go <u>left and right</u>
for example parent function is y=|x| to go <u>right </u>3 you do y=|x-3|
a.goes down 3, and 2 to the right
y=|x-2|-3
b. 3 down and 1 to the left
y=(x+1)²-3
c. 5 up and 2 to the right
d. 1 up and 5 to the right
The actual inverse function is:

And the domain is [0, ∞).
<h3>
Where is the mistake?</h3>
Remember that for a given function f(x) with a domain D and a range R.
For the inverse function, f⁻¹(x) the domain is R and the range is D.
Here, for the given function the domain is x ≥ 3 and the range is [0, ∞).
Then for the inverse function, which is:

(to check this, you must have that):

The domain will be [0, ∞) and the range x ≥ 3
