Answer:
91 grams
Step-by-step explanation:
To get a percentage you go the number which you want the percentage of divided by the full number then multiply all that by 100. For example, (10 / 100) x 100 = 10, so 10 is 10% of 100.
Now lets call the answer x:
(x / 130g) x 100 = 30%
Now you need to get x on its own, so you need to rearrange it:
x = (30 x 130) / 100
When you change the sides, you change the signs.
With this equation we can work out what 30% of 130 is. So,
(30 x 130) / 100 = 39g
So, 39g is 30%. To find out how much sugar is in the diet juice you need to subtract this from the regular cranberry juice sugar:
130 - 39 = 91g
So there is 91 grams of sugar in a serving or diet juice.
Answer:
C) x also increases 5 times its original value
35/5=7
70/10=7
Step-by-step explanation:
Given:
z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3
Solution:
X ~ N (8, 3)
For day 1, n = 5
P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z <
=2.23) = 0.987126
For day 1, n = 6
P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z <
=2.45) = 0.992857
For both days:
P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) =
0.9801
Answer:
No
Step-by-step explanation:
A matched pair design is used when we have two different observation about a certain experiment for each subject such that there is a natural pairing between the two population.
In the scenario described above, we have 20 subjects of which 10 are boys and 10 are girls.
Matching boys and girls having similar numbers does not depict natural pairing and thus using a matched paired test would be inappropriate. The test to use for such experiment is the two population t test.
