The answer I got was x= 21/2
Answer:
The first one is 79
The second one is 26
I hope this helped! :D
Step-by-step explanation:
For the first one you just plug in 23 into x so it would be 3(23) + 10 = x
For the second one you just plug in 88 into g so it would be 88 = 3x + 10
1. Answer:
30 is your frequency
Step-by-step explanation:
Frequency in this case would be the number of winners. So to find the frequency we would need to add up the total number of winners in the histogram.
So, 0 + 2 + 5 + 6 + 8 + 5 + 4 = 30
2. Answer:
6 (you already put that)
3.
The median can be found in the 50-59 bin or interval.
Answer:
B. 12.5
Step-by-step explanation:
We have the lowe confidence interval = 185
The upper confidence interval = 210
Mean of X = (lower confidence + upper confidence interval)/2
Mean of X = 185 + 210/2
= 197.5
The margin of error = the upper confidence interval - mean of X
= 210-197.5
= 12.5
