Answer:
Option A is correct.
0.7734.
Step-by-step explanation:
Definition: z-score indicates that how many standard deviations an element is from the mean.
It can be calculated from the following formula.

where;
z is the z-score,
X is the value of the element,
is the mean, and σ is the standard deviation.
To interprets z- score:
- if a z-score < 0, it represents an element less than the mean.
- if a z-score > 0, it represents an element greater than the mean.
- if z-score = 0, it represents an element equal to the mean.
Given: z < 0.755
then,
to find the value of z, look up the standardize normal distribution to the left of a z-score.
we get
z = 0.7734
Domain = all possible x values
You can see it starts from -5 and it goes till 4. Therefore domain -5 < x < 4
Solution: [-5,4]
Answer:
By rounding up of the constant and coefficient terms, we have;
The line of best, fit is y = 1.23 + 3.46 × 10⁻²·x
Step-by-step explanation:
The table for the data on the number of movie admissions each year is presented as follows;
Year, x
Admission, y
0
1.24
2
1.26
4
1.39
6
1.47
8
1.49
10
1.57
Using a graphing calculator, we have that the line of best fit is given by the following equation;
y = 1.23047619048 + 3.45714285714 × 10⁻²·x
Which is approximately, y = 1.23 + 3.46 × 10⁻²·x
Circumference of a circle is 2(pi)(r)
2(3.14)(7)= 43.96
So the answer is B
