X = 650 + 60t
The cheetah must arrive at the same place at the same time:
x = 90t
650 + 60t = 90t
30t = 650
t = 650/30 ≅ 21.7 s
It takes the cheetah a little more than 20 s running at 90 ft/s to reach the moving antelope, so assuming the antelope can maintain its speed of 60, it is safe.
Answer:
11
Step-by-step explanation:
Probability of Max making a shot is 45/60=¾
Here, probability, p=¾ or 0.75
The trials n=15
E=np where E is expectation
Now, when the shots out of 15 trials will be given by np=15*¾=11.25 shots
Rounded off to the nearest interger, this is approximately 11 shots.
Therefore, the possible number of shots in 15 trials for Max is equivalent to 11
Answer:
I've attached a graph with this, that's your answer
Y is equal to 54. (B)
A triangle has a total degree of 180. Given that two of the angles are the same and the last angle is 72 degrees, you can subtract 72 from 180 to get 108. From there, You can divide 108 by 2 (because there are two equal parts) to get 54.
