Answer: 2,000 milliliters.
Step-by-step explanation:
Hi, to answer this question we have to add the amount of water and the amount of sports drink that he drank:
1 liter + 1 liter = 2 liters of liquid.
Finally, we have to convert the result into milliliters.
Since 1 liter = 1000 liters
We have to multiply the liters drank by 1000.
2 x 1000 = 2,000 milliliters.

Answer:
Approximate probability that is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean = 2.2
Standard deviation = 1.4
Sample size ( n ) = 52
Let be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that is less than 2 =
= Putting
= ( Using Z table )
= 0.1515
This might be the answer I hope
Answer:
80
Step-by-step explanation:
Plug it in.
So 5 x 2 (4 x 3- 2 x 2)
5x2(12-2x2)
5x2(12-4)
5x2(8)
(10)(8)
So, the answer is 80.
