Answer: 0.0078
Step-by-step explanation:
We assume that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 12.00 oz and a standard deviation of 0.12 oz.
As per given , we have
and 
Sample size : n= 5
Let 
be the sample mean amount of coke in can.
Then, the probability that a sample of 5 cans will have a mean amount of at least 12.13 oz will be :_
[By using z-table]
Hence, the required probability = 0.0078
Answer:
3943000
Step-by-step explanation:
Just ignore the "394" and keep the "2588."
2588 is not smaller than 2500
But 2588 <em><u>IS </u></em> bigger than or equal to 2500
So, you round up.
= 3943000
Answer:
When Amina is 18. Saad would be;
k. 14
Step-by-step explanation:
Let "x" represent Anita's current age and let "y" represent Saad's current age, we have;
Anita's age = 2 × Saad's age
Therefore;
x = 2 × y...(1)
In 4 years, we will get;
x + 4 = 1.5 × (y + 4)...(2)
Substituting the value of x in equation (1) into equation (2), we get;
2·y + 4 = 1.5·y + 1.5 × 4 = 1.5·y + 6
2·y + 4 = 1.5·y + 6
2·y - 1.5·y = 6 - 4 = 2
0.5·y = 2
y = 2/0.5 = 4
Saad's current age = y = 4 years
From equation (1), we have;
x = 2 × y = 2 × 4 = 8
Amina's current age = x = 8 years
When Amina is 18, we have;
18 = 10 + 8 = 10 + x
Therefore, Amina would be 18 in 10 years time from now, from which we have;
Saad would be 10 years + y = 10 years + 4 years = 14 years in 10 years from now
Therefore, when Amina would be 18 years in 10 years from now Saad would be 14 years.
