Answer:
x - 31 69
Tonisha has to make at least $100 in revenue
Step-by-step explanation:
Set up the inequality:
x - 31 represents her profit
Since she wants to make at least $69 a day, use 69
So, the inequality is x - 31 69
Then, solve for x to find how much she has to sell:
x - 31 69
x 100
So, Tonisha has to make at least $100 in revenue
The ex- suffix often correlates a word to mean "outside", while the in- suffix often correlates a word to mean "inside". An exterior angle of a polygon would mean "an angle outside of a polygon". An interior angle of a polygon would mean "an angle inside of a polygon". Three exterior angles of this polygon would be angle B, angle D, and angle A. This is because these angles are outside of the polygon due to the extending lines from the shape. Two interior angles of this polygon would be angle 6 and angle 8 (explanation was given when I first began answering this question). Angle 9 would be exterior since it is outside of the polygon. Two exterior angles of the polygon that are congruent are angle D and angle 9, since they are both 90 degrees (right angles).
Step-by-step explanation:
<u>Step 1: Set x equal to 0 to find the y-int</u>
→ Not an exponential equation
→ 10,000 → Works for first test
→ 10,000 → Works for first test
→ 10,000 → Works for first test
<u>Step 2: Set x equal to 1</u>
→ 6,000 → Works for second test
→ 4,000 → Does not work for the second test
→ 14,000 → Does not work for the second test
Answer: The answer is Option B
Answer:
There is a relationship between the age of a young adult and the type of movie preferred.
Step-by-step explanation:
In this case we need to test whether there is a significance relationship between the age of a young adult and the type of movie preferred.
The hypothesis can be defined as:
<em>H₀</em>: Age of a young adult and movie preference are independent.
<em>Hₐ</em>: Age of a young adult and movie preference are not independent.
The test statistic is given as follows:
Consider the table below.
The formula to compute the expected frequencies is:
The Chi-square test statistic value is:
The significance level of the test is, <em>α</em> = 0.05.
The degrees of freedom of the test is,
df = (r - 1)(c - 1)
= (3 - 1)(3 - 1)
= 2 × 2
= 4
Compute the <em>p</em>-value as follows:
<em>p</em>-value = 0.6266
*Use a Chi square table.
As the <em>p-</em>value is more than the significance level the null hypothesis was failed to be rejected.
Thus, concluding that there is a relationship between the age of a young adult (18 to 35 years old) and the type of movie preferred.
