And you're fine that on his way to work he waits time for the bus is roughly uniformly distributed between 8 minutes and 17 minutes 1 day he time his weight and writes down a number of minutes ignoring the 2nd run a solution to 3 decimal places
Answers
We have the waiting times uniformly distributed between 8 and 17 minutes. As he ignore the seconds, we have a discrete distribution with values 8 to 16.
We have to find what is the probaility that the waiting time is 10 minutes.
We can find this probability knowing that 10 is one class out of 17-8=9 classes with equal probability.
So the probability is:
[tex]P(X=10)=\frac{1}{9}\approx0.111[/tex]We now have to calculate the probability that the waiting time is between equal or higher 11 and less than 13. This include classes 11 and 12 (and not 13), so we include 2 classes out of 9. Then, the probability is:
[tex]P(11\le X\le13)=\frac{2}{9}\approx0.222[/tex]Answer:
P(X=10) = 0.111
P(11<=X<13) = 0.222
the following frequency data shows the number of States including the District of Columbia that favorite each party in the presidential popular vote in 1976 and 2012. Drag and drop the correct equations and inequalities into the boxes to complete the explanation
Answers
The conditional relative frequency that a state was won by the Democrat in 2012, given that a Democrat won the state in 1976 is: 12 (won by the Democrat in 2012 and also in 1976)/24(Total won by the Democrat in 1976)= 50 %
The conditional relative frequency that a state was won by the Republican in 2012, given that a Republican won the state in 1976 is: 12 (won by the Republican in 2012 and also in 1976)/27(Total won by the Republican in 1976)= 44.4 %
Since 44.4 % < 50%, the 2012 Republican candidate was slightly less likely to win a state that had voted for the party's candidate in 1976 than the Democratic candidate.

Answers
The probability of choosing something made of metal is 0.5.
Let the wooden shield and set of medieval knight's armor be a combination 1.
And the sword, a set of wooden nunchucks, a giant wooden club, and a deadly pair of fists be a combination 2.
Al the wooden piece of combination 2 will come under one category and the metal piece be in another category.
Similarly, in combination 1 wooden piece is in one category, and the metal piece is in another category.

What is called in probability?Probability is a branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely a proposition is to be true. The probability of an event is a number between 0 and 1, where 0 indicates the event's impossibility and 1 indicates certainty. Probability and possibility are synonymous. It is a branch of mathematics that deals with the occurrence of a random event. The value ranges from 0 to 1. In mathematics, probability has been introduced to predict the likelihood of events occurring.The probability of an event occurring is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

9.7 x 10^5
4.85 x 10^10
4.85 x 10^5
Answers
Answer:
4.85 x 10^5
Step-by-step explanation:
First you want to find 5.6 x 10^5 into simplified form, which is 560000.
Then, you want to find 4.1 x 10^5 into simplified form, which is 410000.
Then you can add these numbers together to get 970000.
970000 into scientific notation is 9.7 x 10^5.
CORRECTION:
Answer should be based off of the AVERAGE viewers, not total.
Average viewers is 485000
485000 in scientific notation is 4.85 x 10^5
The average number of viewers over the two weeks are 4.85 x 10^5
A tv show had 5.6 x 10^5 viewers in the first week
and 4.1 x 10^5 viewers in the second week.
What is an average number:
This is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers.
To find the average number of viewers over the two weeks
Remove the decimal point.
5.6 x 10^5 write like this 560000
Similarly, 4.1 x 10^5 write like this 410000
Now, Solving the question
Therefore, the average will be
560000 + 410000
= 970000/2
=485000
=4.85 X 10^5
and 4.85 x 10^5
Thus , the average number of viewers over the two week 4.85 x 10^5

The error interval for car and person are:
2275 ≤ 2276 < 2276.5 and 60.55 ≤ 60.6 < 60.65 respectively.
Given, the mass of a car is 2276 kg.
we are asked to determine the nearest kilogram.
the car: rounded to the nearest kilogram
so 2275 ≤ 2276 < 2276.5
therefore, a = 2275.5
and b = 2276.5
The mass of a person is 60.6 kg.
we need to round it to 1 decimal place.
the person: rounded to 1 decimal place,
so, 60.55 ≤ 60.6 < 60.65
therefore, a = 60.55
and b = 60.65
Hence the error interval for the combined mass, m, of the car and the person is 2275 ≤ 2276 < 2276.5 and 60.55 ≤ 60.6 < 60.65 respectively.

An advertiser rents a rectangular billboard that is 44 ft wide and 20 ft tall. the rent is $15 per square foot. for a billboard twice as tall, the advertiser has to pay $26,400. is this reasonable? explain.
Answers
Yes; when the height is doubled, the area is also doubled (option D)
Explanation:width of the billboard = 44 ft
height of the billboard = 20 ft
the rent per square ft = $15
for a billboard twice as tall, the advertiser has to pay $26,400
We need to find the area of the billboard = width × height
Area = 44 × 20
Area of the billboard = 880 ft²
The rent for the whole area of the billboard = $15 × 880
The rent for the whole area of the billboard = $13,200
when the height is doubled = 2(height)
new height = 2(20) = 40 ft
The new area = 44 × 40 = 1760 ft²
The rent for the new area of the billboard = $15 × 1760
The rent for the new area of the billboard = $26400
The result in our calculation is the same as the amount the advertiser payed.
new height = 2(old height)
new area = 2(old area)
26400 = 2(13200)
We can conclude: it is reasonable
Yes; when the height is doubled, the area is also doubled (option D)
