Hiking up a mountain, you notice that the air temperature drop 10°C for every 1,00 meters in elevation. The temperature was at 68°F at 2,000 meters in altitude. If the hiker is now at altitude of 5,000 meters, what is the current temperature? Show your work.
Answer:
you're given a *rate* of decrease and then the *extent* of the "cause". SO the rate is 10C/1000m (right? You understand why this is a rate? You go 1000m up, the temperature drops 10C. And it happens continually, bit by bit, as you climb. That's a rate!
But, you don't stop with climbing just 1000m: you climb 1000m twice *more*. So, how much has the temperature dropped in all, by the end?
You really should be able to put this together as 10C/1000m x 3000m = result. It will be in units of (degrees) C.
Now, finish the problem and get down the mountain, before you freeze (also, winds kick up more on mountains -- a double whammy).
Step-by-step explanation:
a traffic study has shown that the probability that 55 cars will pass over a small bridge in a 4-4-minute period is 0.16.0.16. what are the odds against exactly 55 cars passing over the bridge in that time?
in a large population, 71% of the people have been vaccinated. if 5 people are randomly selected, what is the probability that at least one of them has been vaccinated?
The probability that AT LEAST ONE of them has been vaccinated is 0.9979.
Vaccination rate among the population: p = 0.71
Sample size = 5
Assume that X people have received vaccinations.
P(atleast one) = 1 - P (none)
By the binomial distribution, now,
P(none)= (⁵₀) 0.71° (1-0.71)⁵⁻⁰
= 1 × 1 (0.29)⁵
= 0.0021
So,
P(at least one) therefore equals 1 - P (none)
= 1 - 0.0021
= 0.9979
Therefore, the probability that AT LEAST ONE of them has been vaccinated is 0.9979

b. If both the upstairs and downstairs switches are in the up position, will the light be on?
Explain your reasoning.
If both the upstairs and downstairs switches are in the up position, the light will be off
How to determine if the light will be on?The given parameters are
Switches = 2 i.e. top and bottom
Also, we have:
When the upstairs switch is up and the downstairs switch is down, the light is turned on.
This means that the light is only on when the upstairs switch is up and the downstairs switch is down
Any other position of the switches, the light is off
From the question, we have
Both the upstairs and downstairs switches are in the up position
This is different from the required position to on the light

The producers of a concert are going to use
television screens to show larger-than-life images
of the band using a scale of 2 inches = 3 feet.
The lead singer of the band is 6 feet 2 inches tall,
now tall will the singer be on the screen?
144 feet
111 fost
63 feet
9 feel
Answer:
111 feet
Step-by-step explanation:
The scale used to blow up the the lead singer (and the band) is
2 in : 3 feet
==> 1 in : 3/2 feet
Let X be the height of the band leader in inches and the blown-up image be Y
X = 6' 2" = 6 x 12 + 2 = 72 + 2 = 74"
Then Y = (3/2) x H
Y = (3/2) x 74" = 111 feet

Using linear functions, it is found that:
Plan A is cheaper for less than 150 messages.Plan B is cheaper for more than 150 messages.What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.For each plan, we have that:
The slope is the cost per message.The intercept is the fixed monthly cost.Hence the cost functions for sending x messages are given as follows:
A(x) = 0.1x.B(x) = 12 + 0.02x.The costs will be the same when:
A(x) = B(x)
Hence:
0.1x = 12 + 0.02x
0.08x = 12
x = 12/0.08
x = 150.
Due to the lower intercept of plan A, and the lower cost per message of plan B, we have that:
Plan A is cheaper for less than 150 messages.Plan B is cheaper for more than 150 messages.More can be learned about linear functions at https://brainly.com/question/24808124

Bob is interested in examining the relationship between the number of bedrooms in a home and its selling price. After downloading a valid data set from the internet, he calculates the correlation. The correlation value he calculates is only 0. 5. What does bob conclude?.
Bob after downloading the valid data set from the internet and calculating the correlation values as 0.5 concludes that as the number of bedrooms in a home increases its selling price also increases.
This happens because as there is an increased demand for the number of bedrooms in a home there should be enough supply in the market to fulfill the requirements. So, there should be a surplus of beds in the market and for that the selling price increases to maintain the surplus.
The law of Demand states that as the demand for a particular commodity or a product increases its price also increases. The above example of Bob gets verified according to the Law of Demand.

Matthew scored −33 points in his turn at a video game. In Genevieve's turn, she scored fewer points than Matthew.
Use absolute value to describe Genevieve's score as a loss.
Genevieve lost more than 33 points in her turn at a video game.
Absolute value describes a number's distance from zero on the number line without taking direction into account. A number's absolute value is never negative.
Given that Matthew's score is −33 points.
In Genevieve’s turn, she scored lesser points than Matthew in her turn at a video game.
Let y be the points scored by Genevieve.
Then we have y < -33
⇒ | y | > | -33 | (Using absolute value on both sides)
⇒ | y | > 33
The absolute value of y can be any number greater than or equal to 34, while Genevieve's point in her video game turn is less than or equal to -34.

Show how to convert 83 1/3%
Answer:
5/6
Step-by-step explanation:
83 1/3% =
= (83 + 1/3)% <------- the mixed numeral 83 1/3 is the same as 83 + 1/3
= (249/3 + 1/3)% <---- to add 83 + 1/3, use the common denominator 3
= 250/3 % <---- the sum of 83 and 1/3 is 250/3, but this is still percent
= (250/3) / 100 <---- to change percent to decimal, divide percent by 100
= 250/300 <---- now we need to reduce this fraction
= 25/30 <---- divide numerator and denominator by 10
= 5/6 <---- divide numerator and denominator by 5
The difference in the x-coordinates of two points is 3, and the difference in the y-coordinates of the two points is 6. What is the slope of the line that passes through the points? 2 3 6 9
Solution :
the differences in the X coordinates and Y coordinates:
The x-coordinate tells you how many steps you have to take to the right (positive) or left (negative) on the x-axis. And the y-coordinate tells you have many steps to move up (positive) or down (negative) on the y-axis.
Given : difference in the x-coordinates of two points is 3
the difference in the y-coordinates of the two points is 6
The slope of the line :
In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.
The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.
Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,
m = change in y/change in x = Δy/Δx
Where “m” is the slope of a line.
Tan θ = Δy/Δx can also represent the slope of the line
So, tan θ to be the slope of a line.
Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The letter ‘ m’ usually represents the slope.
If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:
Slope,
m = Change in y-coordinates/Change in x-coordinates
m = (y2 – y1)/(x2 – x1)
Therefore, based on the above formula, we can easily calculate the slope of a line between two points.
In other terms, the slope of a line between two points is also said to be the rise of the line from one point to another (along the y-axis) over the run (along the x-axis). Therefore,
Slope, m = Rise/Run
Use the slope formula.
the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or
the change in the y values over the change in the x values.
The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2. It does not matter which point you label as the first point and which you label as the second. Don't forget to include the correct sign of each value. Simplify to get the value of the slope. Check the your answer by graphing the points and verifying that the vertical distance between the two points and the horizontal distance between the two points is captured by the numerator and denominator of the slope

D. 15
A box can hold up to 15 items ensuring that every box contains the same quantity of items.
Given there are 10 rulers and 25 packages of tape.
Only one type of item may be present in each box.
Simply put, probability is the likelihood that something will occur.We can discuss the chance or likelihood of various outcomes when we don't know how an event will turn out. Statistics is the study of events that follow a probability distribution.The chance of an event happening is equal to 1 if there is no doubt about its likelihood. In other words, there is a 1 in the chance of an event. An event's probability is zero if there are no chances that it will occur.
In the event when 25 packages of tape and 10 rulers have to be placed in a box, the answer is 25 - 10 = 15.
then only 15 items that can be placed in a box so that each box has the same number of items.
