The LCM of 120 and 150 is 600
Answer: 25:15
Step-by-step explanation: in the ratio 5:3 the 5 is dogs and the 3 is cats you multiply the 5 (aka the dogs) by 5 to get 25 (the amount of dogs in the shelter) when you multiply 3 by 5 you get the amount of cats which is 15, a good way to remember is what you do to one side you have to do to the other. I hope this helps.
Answer:
a) No, since 80 is less than 2.5 standard deviations above the mean; b) Yes, since 80 is more than 2.5 standard deviations above the mean.
Step-by-step explanation:
For part a,
The mean is 70 and the standard deviation is 5. This means that 2 standard deviations above the mean is 70+5+5 = 80.
This means that 80 is not an outlier, as it is not more than 2.5 standard deviations above the mean.
For part b,
The mean is 70 and the standard deviation is 3. This means that 2 standard deviations above the mean is 70+3+3 = 76; 3 standard deviations above the mean is 70+3+3+3 = 79. 80 is more than this, so yes, it is an outlier.
