Answer: The $75 rebate.
Step-by-step explanation: When you have a question that deals in percentages, you would place a decimal point in the second point back--- Or rather, it would be 1.00 at 100% and above, and .05 for 5%. You would be getting $71.25 discount with the 15%, while you would be getting $3.75 more with the $75 rebate.
The answer is A, “Obtuse triangle.”
A.) The completed table is in the attached picture.
Per capita calculation steps Step 1: Per capita = MV Deaths / Population
Step 2: Convert to Scientific notation
Step 3: Round-off to hundredths (2nd digit from the right of decimal place)
Per 100K people calculation steps Step 1: Per 100K people = MV Deaths / Population * 100, 000
Step 2: Round-off to tenths (1st digit from the right of decimal place)
B) I used my completed table (attached picture)
Therefore,
Indiana has the worst rate with 11.6 MV Deaths per 100K People
C) Again, I used my completed table (attached picture)
Therefore,
Illinois has the best rate with 7.3 MV Deaths per 100K People
Answer:
The 99% confidence level for the proportion of all American youngsters who are seriously overweight is (0.137, 0.163)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
For this problem, we have that:

99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 99% confidence level for the proportion of all American youngsters who are seriously overweight is (0.137, 0.163)
Answer:
105 boats
Step-by-step explanation:
Let x be the total number of boats in the marina.
If Two-thirds of the boats in the marina are white.
Fraction of the remaining boat= 1-⅔ =⅓
4/7 of the remaining boats are blue.
4/7 of ⅓ are blue
4/7 X ⅓ = 4/21 are blue
Fraction of Red Boats =
1-(Proportion of white Boats +Proportion of Blue Boats)
= 1-(2/3+4/21)=1/7
If there are 15 red boats,
1/7 of the total boats =15
1/7 X x=15
x=15X7
x=105
There are 105 boats in total on the marina
