Answer:
253.90
Step-by-step explanation:
Answer:
B- It cannot be answered without additional information.
Step-by-step explanation:
From the question, we have α= 0.01 and α= 0.05.
Thus;
We can decide to look at the critical values and check if test statistic is less or more than the tabulated value for α= 0.01 and 0.05.
However, that will not be sufficient as neither the level of significance nor confidence level is clearly mentioned in the question and thus, we can not answer it without additional information.
Answer:
10 units

<em>"In the xy-plane, the parabola with equation y = (x − 11) ² intersects the line with equation y = 25 at two points, A and B. What is the length of AB" </em>
Here is my answer
Because the parabola intersects the line with equation y = 25 Substituting y = 25 in the equation of the parabola y = (x - 11)², we get
25 = (x - 11)²
<=>x - 11 = ± 5
<=> 
Thus A(16, 25) and B(6, 25) are the points of intersection of the given parabola and the given line.
So the length of AB = √[(16 - 6)² + (25 - 25)²]
= √100 = 10 units
Answer:
10 is real, rational, integer, whole, natural
5/6 is real, rational
sqrt of 24 is real, irrational
0 is real, rational, integer, whole
sqrt 81 is real, rational, integer, whole, natural

Answer:
There were 89 retail stores in 1997.
Step-by-step explanation:
You know:
y = 11*x + 12
where y is the total number of stores and x is the number of years after 1990.
Being this a linear function (Linear functions are those functions that have the form y = mx + b as it happens in this case), to know the total number of stores and, then you must know the value of x, that is, the number of years after 1990, and replace that value in the given function.
To find out how many retail stores there were in 1997, then since 1990 7 years have passed, calculated by subtracting: 1997 - 1990 = 7
So, 7 is the number of years after 1990, then x=7
Replacing in the function y=11*x + 12 you get:
y=11*7+12
Solving:
y=77+12
y=89
