If you are reffering to this dot plot, it would be 13 trees being studied.
Answer:
24/25
Step-by-step explanation:
Cos Z = adj/hyp
= 48/50
= 25
Answer:
$20
Step-by-step explanation:
Bin A: Bin B: Bin W:
white ball: 20% $1: 75% $8: 5/6
black ball: 80% $7: 25% $500: 1/6
first we can calculate the expected return of bins B and W:
expected return if the ball is black = ($1 x 75%) + ($7 x 25%) = $2.50
expected return if the ball is white = ($8 x 5/6) + ($500 x 1/6) = $90
expected return of the game = (expected return of a black ball x probability of choosing a black ball) + (expected return of a white ball x probability of choosing a white ball) =($2.50 x 80%) + ($90 x 20%) = $2 + $18 = $20
The interval that contains the median response time is; 50 - 60 seconds
<h3>What is the median of the histogram?</h3>
The median of a histogram is defined as the middle element of the histogram.
Now, in this histogram given, we see that the y-axis is for the relative frequency, while the x-axis is the Response time (in seconds).
Observing this histogram closely, it is clear that the response times are all symmetrical around the interval 50 - 60 seconds as it is also the middle element of the histogram.
Thus, we can conclude that the interval that contains the median response time is; 50 - 60 seconds
