Answer:
70
Step-by-step explanation:
First add the tens: 20 + 30 + 10= 60
Now add the Ones: 7 + 2 + 4= 13
now add them all together: 60+13=73
so the best estimate is 70

Answer:
660
Step-by-step explanation:
33/0.05
A line perpendicular to y = 2x - 1 must have the slope -1/2 (negative reciprocal of 2).
Thus, the eq'n of the new line is y+2 = (-1/2)(x+2).
Based on the characteristics of the distribution, the probability that the first goal is scored in less than 4 minutes is 0.
<h3>What is the probability?</h3>
For us to be able to calculate the probability that the first goal is scored in less than 4 minutes, the distribution needs to satisfy the requirements of the Central Limit Theorem(CLT).
Based on the fact that the distribution here is extremely right skewed, then it does not satisfy the requirements of CLT so the probability is 0.
First part of question:
The distribution of the time it takes for the first goal to be scored in a hockey game is known to be extremely right skewed with population mean 12 minutes and population standard deviation 8 minutes.

X = 59, y = 44
2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59
x - 15 = y
59 - 15 = y
44 = y
