Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Margin of error = 0.5 years
Standard deviation = 5
At 90% confidence, z = 1.645
We need to find the minimum size of the sample they must take.
So,

Hence, Option 'd' is correct.
Answer:
Dependent: fee
Independent: time
Step-by-step explanation:
The scenario described in question indicates that fee is the dependent variable and time is independent variable. The reasoning is that fee depends on the time(hour). The fee will increase as the time increases. Whereas change in time cause change in fee. So, fee is the dependent variable and time is independent variable.
This question means that Coca-Cola, which has 65 grams of sugar in a can (I assume), has the same sugar content as 1.383 kg of carrots. Coca-Cola is a distractor in this problem. (1.383kg/65g)=(1kg/s)
Can you solve from there for s?
The angle would be 70 degrees because 180-110=70
Answer:
5 gallons of water must be added.
10 gallons to start with
adding 'x' gallons of water final volume = 10 + x
.9 (10) = amount of vinegar
.1(10) = amount of water
amount of vinegar before and after water addition is constant
.9(10) = .6(10+x)
9 = 6 + .6x
3 = .6x
x = 5 gallons of water to be added
