B) The ages are more consistent
C) The interquartile range is 15
D) The median ages of attendees are greater
Answers
Option B. is correct. Using box plot, the statement that apply to movie A is the ages are more consistent.
What is box plot?
A box plot is "a special type of diagrams that shows quartiles in a box and the lines extending from the lowest to the highest value".
According to the question,
The box plot shows ages of randomly sampled attendees at two different movies.
- The statement A. The range of the ages are greater. This statement is false because in the box plot movies A is range is 35 (subtract highest value from lowest value) that is not greater. Thus, this statement is false.
- Statement B. The ages are more consistent. This statement is true. To find consistency in box plot using hypotheses test we get consistency. Thus, the ages are more consistent.
- Statement C: Using value in box plot the interquartile range is Q₃ - Q₁. Where Q₃ - Q₁ = 42.5 - 17.5 = 25. Thus statement is false.
- Statement D: In box plot the median ages of attendees are greater. This statement is false.
Hence, the ages are more consistent in box plot shows age of randomly sampled attendees at two different movies.

Answer:
75%
Step-by-step explanation:
We know that the quarterback has completed 30 of 40 passes. This means that the ratio of completed passes to total passes is 30:40. Converting this to a fraction, we get 30/40, which can be simplified to 3/4. 3/4 as a percentage is 75%. Therefore, the final answer is 75%.
Answers
The only problem is half of 3/4 is 3/8 so it's not exactly 1/3 but it's pretty close.
Hope it helps! Sorry for not being completely sure! Please let me know if it was the right answer or not if you figure it out ^-^

= 4+ 1/9
= 4* (9/9)+ 1/9 (because 9/9=1, it won't change the result).
= (4*9)/9 + 1/9
= 36/9+ 1/9
= 37/9
The final answer is 37/9~

The required hours is 20 hours, where both companies cost the same.
Given that,
The painting company charges $250 base plus $16 per hour. Another painting company charges $210 base plus $18 per hour. How long is a job for which the two companies costs are the same is to be detrmined
What is the cost price?
Cost price is the price for the buyer pays to the seller for an object or product.
Here,
let the total cost for both the companies be y and the painting hour is x.
The painting company charges $250 base plus $16 per hour.
y = 250 + 16x - - - - - (1)
Another painting company charges $210 base plus $18 per hour.
y = 210 + 18x - - - -- - (2)
Solving equation 1 and equation 2.
250 + 16x = 210 + 18x
2x = 40
x = 20
Put this x in equation 1,
y = 250 + 16 * 20
y = 250 + 320
y = 570
Thus, the required hours is 20 hours, where both companies cost the same.
