Answer:
(A) 4
Step-by-step explanation: The mean is all the numbers added divided by the amount of numbers. so 2 + 3+ 6 + 5 = 16 then you add the 4 that is 20 then divide 20 by 5 and if the answer is 4 its correct. The answer is 4 so its correct.
Answer:
<u> x | y </u>
<u> -1 | 2 </u>
<u> -0.5 | -0.25</u>
<u> 0 | -1 </u>
<u> 0.5 | -0.25</u>
<u> 1 | 2 </u>
<u>The graph is attached.</u>
Step-by-step explanation:
You have the following function:
By definition, the input in the independent value and the output is the dependent value.
Therefore, you must give values to x (input values) and substitute them into the function to obtain y for each value (output values).
Then:
x=-1
x=-0.5
x=0
x=0.5
x=1
Table:
<u> x | y </u>
<u> -1 | 2 </u>
<u> -0.5 | -0.25</u>
<u> 0 | -1 </u>
<u> 0.5 | -0.25</u>
<u> 1 | 2 </u>
<u>The graph is attached.</u>
Answer:
The most expensive item you can get is $23.44
Step-by-step explanation:
Because we are adding 8% in tax and 20% in tip, we know that overall we are spending 128% of the total dinner. So, we can divide the $30 we have to spend by 128% in order to find the original price of the item (don't forget to turn the percentage into a decimal first).
$30/1.28 = $23.44
Answer:
f(19)=3/21-4=-3.857
Step-by-step explanation:
f(x)=3/(x+2)-sqrt(x-3)
f(19)=3/(19+2)-sqrt(19-3)
f(19)=3/21-sqrt(16)
f(19)=3/21-4
f(19)=-3.857
