Answer:
Because the dried fruit contains less water
Step-by-step explanation:
Drying is a phenomenon whereby heat is used to remove moisture from a material.
Fruit juice contains about 85% water, that means the remaining fruit content is 25%
The average water content of fruits is about 89%, this means that the remaining fruit content is 11%.
Dried fruit contains about 20% water which means that the remaining fruit content is 80%.
If we assume that each cup serving weighs 1kg this implies that;
The real fruit content (vitamins, minerals etc) masses are;
Fruit juice = 0.25kg
Fruit = 0.11kg
Dried fruit = 0.8kg
We can see that the mass of the fruit content in the dried fruit is twice more than than of the fruit and fruit juice individually. This is why half cup of dry fruit is equated to one cup of the other two.
Answer:
number of shells zoe gives to dev = 7
number of shells zoe is left with = 55-7= 48
number of shells dev has = 9+7=16
Step-by-step explanation:
let the initial number of shells that dev has be A, and initial number of shells that zoe has be B.
let the number of shells that zoe gives to dev be x.
after giiving x shells zoe is left with 3 times the number of shell as that of dev.
therefore number of shells with zoe = 3×number of shells with dev.
number of shells with zoe = initial shells - x = 55-x
number of shells with dev = initial shells + number of shells he gets
= 9+x
therefore (55-x)=3×(9+x)
55-x = 27+3x
55-27=3x+x
4x = 28
x= 7
therefore number of shells zoe gives to dev = 7
number of shells zoe is left with = 55-7= 48
number of shells dev has = 9+7=16
Since the range of the scores given was between 300 and 700 (which is 2 standard deviations below and above the mean), the probability that a randomly selected student's math score - as based on the empirical rule of statistics - is 95%. In decimal form, it is .95.
Answer: high test-retest reliability
Step-by-step explanation: this is because the result of the survey was thesame with the previous result, despite the space of time between when the first survey was conducted and when the second survey was conducted. There was know observable difference in result and if conducted in the next 3 months again, it will give same result, this strongly indicate that the survey has high test-retest reliability.
