0.377 + 5.51 = 5.887
Sorry I can only solve the first one. Could you give me a hint on how to do the second one ?
Answer:
(6.2, 8.8)
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.5 hours
Standard deviation = 1.3 hours
About 68% of adults:
Within 1 standard deviation of the mean. So
7.5 - 1.3 = 6.2 hours
7.5 + 1.3 = 8.8 hours.
So the answer is (6.2, 8.8).
Answer:
y - 0.5x
Step-by-step explanation:
Given that the dog eats the same amount of food each day and on day 3, the available quantity of food
= 12 pounds
On day 7 (4 days after), the available quantity of food is 10 pounds. The difference in the amount of food in 4 days
= 12 - 10
= 2 pounds
This means that each day, the amount of food eaten by the dog in one day
= 2/4
= 0.5 pound
Hence the amount of dog food in the bag y for any day after opening the dog food x will be given as
= y - 0.5x

I checked it and it’s right hope this helps!!
Answer:
one
Step-by-step explanation:
In a function's graph, each x only has one y. A vertical line would only pass one y at any point.
