A class rolled number cubes. Their results are shown in the table.
What is the experimental probability of rolling a number less than 5?
67.8%
49.5%
34.4%
84.7%
Answer:
A. 67.8%
Step-by-step explanation:
the total number of occurences are 202
Now the total number of occurencess for 4 and below are 137
So Heres the quickest way to do it: Divide 137 by 202 then multiply it by 100 being 100%
Then you would get 67.8, then well put the percent sign behind it.

Answer:
1 mi 1927 ft
Step-by-step explanation:
Turn everything into feet:
5mi x 5280 ft/1 mi = 26,400ft + 1,348 ft = 27, 748 ft
3mi x 5280 ft/1 mi = 15,840ft + 4,701 ft = 20,541 ft
Do the subtration that the problem wants you to do:
27, 748 ft - 20,541 ft = 7,207 ft
Turn the answer into mi & ft:
7,207 ft - 5280 ft = 1927 ft
=
1 mi 1927 ft

Howard buys a new comforter set for 15% off the original price of 54$.What is the sale price?
Answer:
$45.90
Step-by-step explanation:
What 15% off means is 85% of the original price ($54). 85% is the same as 17/20. Multiply 17/20 by 54 (or multiply 3/20 by 54 and subtract that from 54) to get the sale price.
(17 * 54)/20 (Multiply 17 by 54)
918/20 (Reduce if needed)
459/10 (Divide 459 by 10)
45.9
The sale price of the comforter is $45.90.

If the distance from point P to point L is the same as the distance from point P to point C, then P is on
Answer:
This answer is C, it is on the perpendicular bisector of segment LC.
Draw any line segment P and L, then another point C anywhere, but the length needs to be the same as PL. You will note that LC (if you connect those points) will become the perpendicular bisector to point P.

Step-by-step explanation:
The train station clock runs too fast and gains 5 minutes every 3 days.
How many minutes and seconds will it have gained at the end of 7 days?
9514 1404 393
Answer:
mm:ss = 11:40
Step-by-step explanation:
We assume the amount of gain is proportional to the time that passes.
g/7 = 5/3
g = 7(5/3) = 35/3 = 11 2/3 . . . . minutes
The clock will have gained 11 minutes and 40 seconds after 7 days.
You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that a prior survey suggests that about 22% of air passengers prefer an aisle seat. Assume that you want to be 98% confident that the sample percentage is within 5.1 percentage points of the true population percentage.
Answer:
358 randomly selected air passengers must be surveyed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
Assume that a prior survey suggests that about 22% of air passengers prefer an aisle seat.
This means that [tex]\pi = 0.22[/tex]
How many randomly selected air passengers must you survey?
We need a sample of n, and n is found for which [tex]M = 0.051[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.051 = 2.327\sqrt{\frac{0.22*0.78}{n}}[/tex]
[tex]0.051\sqrt{n} = 2.327\sqrt{0.22*0.78}[/tex]
[tex]\sqrt{n} = \frac{2.327\sqrt{0.22*0.78}}{0.051}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.22*0.78}}{0.051})^2[/tex]
[tex]n = 357.2[/tex]
Rounding up
358 randomly selected air passengers must be surveyed.
Phil bought two hamburgers and a milk shake
for $10.30. Janice bought three hamburgers and
a milk shake for $14.80. What is the cost of the
two milk shakes?
A. $1.30
B. $1.45
C. $2.60
D. $4.50
Answer:
C.
Step-by-step explanation:
[tex]\left \{ {{2x+y=10,3} \atop {3x+y=14,8}} \right.[/tex]
[tex]\left \{ {{y=10,3-2x} \atop {y=14,8-3x}} \right.[/tex]
10,3-2x=14,8-3x
x=4,5 - one hamburger
y=1,3 - one milk shake
OR:
$14,8-$10,3=$4,5 - one hamburger
2*4,5+y=10,3
y=1,3 - one milk shake
2y=2,6

Simplify the rational expression by rationalizing the denominator √15/√6x
Answer:
√10/2x

Create a scenario that requires use of the Fundamental Counting Principle to find the probability. Calculate the probability.
Answer:
see explanation below
Step-by-step explanation:
You have three pairs of shoes (white, brown, and black), and you have 6 pairs of pants ( brown, blue, grey, white, sand, and black)
We use the Fundamental Counting Principle to find the number of possible pant-shoe combinations:
3 * 6 = 18
then we can find the probability of wearing by random selection brown shoes with either blue or grey pants:
prob (brown shoes & blue pants) + prob (brown shoes & grey pants) =
= 1/18 + 1/18 = 2/18 = 1/9
