y = -8
Answer:
Answer:
Quartile Statistics
First Quartile Q1 = 52
Second Quartile Q2 = 53.5
Third Quartile Q3 = 61
Interquartile Range IQR = 9
Median = Q2 x˜ = 53.5
Minimum Min = 49
Maximum Max = 74
Range R = 25
Step-by-step explanation:
Cos theta would be (adjacent side) / (hypotenuse), or 8/29.
Thus, the angle theta would be the inverse cosine of 8/29, which is
1.291 radians or 73.987 degrees.
Given this result, just take the sine of this angle.
Add all the times together:
10 + 25 + 15 = 50 minutes total.
For the ratio divide the time for weights by total time:
25/50 which reduces to 1/2
The ratio is 1/2
