Answer:
125 boxes
Step-by-step explanation:
6,000/48 = 125
6/9 = 2/3
Therefore 2/3 of the students are drinking lemonade.
Answer:
The powers are 3 and 5.
Step-by-step explanation:
When you multiply 2 exponential functions you add the powers and when you divide these functions you subtract the powers, so we have:
11^a * 11^b = 11^(a+b)
11^a/ 11^b = 11^(a-b)
So, from the information given:
a + b = 8
a - b = 2 Adding:-
2a = 10
a = 5.
and substituting in the second equation
5 - b = 2
b = 3.
To get from 48 to 14 u subtract 34 from 48 to get 14
the ratio of 48:14 is 24:7
68% of the data will be within one standard deviation of the mean, so 68% of delivery times will be at least 27-3=24 and at most 27+3=30.
