Answer:
Density = 1.042 grams.
Step by step: Work out the mass of each three in a unit volume.
Cm of apple juice are mixed with 25 cm3 of fruit syrup and 270 cm3 of sparkling water to make a drink with a volume of 330 cm^3.
Apple Juice is 1.04 grams per cm³.
Fruit Syrup is 1.6 grams per cm³.
Sparkling Water is 0.99 grams per cm³.
0.4L = 400ml
Each student effectively adds 10ml of water so 22 students are adding 10ml of water each. Therefore, 22 x 10 = 220ml total in all the containers added by all 22 students
Water left = 400 - 220 = 180
The answer is B.
Answer:
16 weeks
Step-by-step explanation:
Assuming that each month is around 4 weeks, multiply that number by 4 months and you will get 16 weeks in total.
We can only look up the value in the normal distribution table if the probability of z is LESS than a certain value AND the value is positive.
If the probability of z is MORE than the value, then you need to do 1 minus the probability.
I.e. 1 - 0.93699
[0.93699 is found in the normal distribution table, searching for 1.53]
However, since the value (-1.53) is also negative, you need to do 1 minus AGAIN.
I.e. 1 - 0.93699
Since you have to do both, the answer should be obtained as follows:
1 - (1 - 0.93699) = 0.93699
Sorry for the terrible explanation :/
And apologies if anything is incorrect. Hope this helped though!
