Answer:
His average for 4 days is 2542.5 mg
Intake of 5th day has to be less than 1330 mg
Explanation:
In order to find the average we take the sum of intakes for 4 day ans then divide it by total number of day which is 4 days.
Average = (2150 + 3005 + 2700 + 2315) / 4
Average = 10170/4
Average = 2542.5 mg
To find the 5th day intake such that average is below 2300 mg:
Let 5th day intake = x
We apply the same method to find the average by taking the sum of intakes for 5 days and then dividing the total with 5 days now. This average has to be less than 2300 mg therefore we use the following method:
(2150 + 3005 + 2700 + 2315 + x ) / 5 < 2300
2300 = (10170 + x)/ 5 < 2300
10170 + x < 11500
x < 11500 - 10170
x < 1330 mg
Answer: The weight of a baby at 16 weeks will be 15.02 pounds.
Explanation:
Hi, to answer this question we simply have to replace y=16 (number of weeks) in the equation given:
y = 6.7 + 0.52t
Replacing with the value given:
y= 6.7 + 0.52(16)
Solving for y (weight)
y = 6.7+8.32
y = 15.02
The weight of a baby at 16 weeks will be 15.02 pounds.
