Answer:
B. 12.5
Step-by-step explanation:
We have the lowe confidence interval = 185
The upper confidence interval = 210
Mean of X = (lower confidence + upper confidence interval)/2
Mean of X = 185 + 210/2
= 197.5
The margin of error = the upper confidence interval - mean of X
= 210-197.5
= 12.5
Answer:
A. c = 0.31b
Step-by-step explanation:
$7.44 = 24 juice bottles
[Divide by 24 on both sides]
$0.31 = 1 juice bottle
The cost is equal to the amount per juice bottle times the number of juice bottles, so:
c = 0.31b
(A trick to use when you don't know the answer: If there are multiple answers with the same numbers but the decimal places are in different places, it is probably one of those answers.)
<span>Presumably, the opposite of decimals are fractions because by dividing the two numbers you get the decimal value of the fractional form of the number. Refer to the example below.
How do you write 39/100 into a decimal form is by simply dividing 39 to 100. </span>
<span>Hence, </span>
1. 39 / 100 = 0.39 -> Hence this is the decimal form.
<span>0.39 is the decimal form of the given value. </span>
<span>Other examples can include: </span>
<span><span>1. </span> 100 / 1000 = 0.1</span> <span><span>
2. </span> 45 / 10 = 4.5</span><span>
