Answer:
[tex]\boxed {\tt -4 \textdegree \ per \ hour }[/tex]
Step-by-step explanation:
This question asks us to find the average rate of change in temperature per hour.
Therefore, we must divide the temperature change by the hours.
[tex]rate \ of \ change =\frac{temperature \ change}{hours}[/tex]
The temperature dropped 24 degrees in 6 hours. Since it dropped, the change was negative.
[tex]temperature \ change = -24 \textdegree \\hours = 6 \ hours[/tex]
Substitute the values into the formula.
[tex]rate \ of \ change =\frac{-24 \textdegree}{6 \ hours}[/tex]
Divide.
[tex]rate \ of \ change = - 4 \textdegree / hour[/tex]
The average change in temperature was -4° per hour. The temperature dropped 4 degrees each hour.
A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degrees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored. What is a strong counterargument?
Answer
:we are told that every year the temperature rises by 0.08degrees Centigrade,
So the difference between margin of error and the increase is much higher
That is
0.15-0.08=0.07
But remember Margin of error=Critical value *Standard deviation of population
And it is a quantity that measures accuracy
So the counter argument is that this is still an increase and it should be considered.
.
Answer:
The difference with any previous decade is much greater than the margin of error

Answer:
Why is college important? It’s a question you may have heard among friends, or perhaps you’ve even wondered yourself about the benefits of earning a degree. And it’s a good question to be asking as you consider your future—and everything that will include, from earnings potential to starting or switching your career. Here are five facts you should know as you consider the value of a college education.
1. People with college degrees earn more on average.
According to averages calculated by the US Bureau of Labor Statistics (BLS), people with a bachelor’s degree earn around 64% more per week than individuals with a high school diploma, and around 40% more than those with an associate’s degree. Those with an associate’s degree earn around 17% more than those with a high school diploma.
Over the course of a year (52 weeks), those percentage differences add up. For example, if you compare the average median annual earnings for those with a bachelor’s degree to those with a high school diploma, you’ll discover a difference of almost $24,000 per year in income.
2. College can help you expand your network.
Salary is far from the only answer for why is college important. You may have heard this before, but who you know and who your friends know is important. No matter how talented you are, a strong network can help you start and advance in your career.
At an Art Institutes school, you’ll not only have the chance to connect with instructors* who have worked in their fields, but you can also meet students in a variety of creative fields. These diverse connections may well benefit you in the future. Plus, you can also participate in professional groups, community activities, and industry conferences where you can grow your circle even more. Your Career Services department may also connect you with alumni in your field and can continue to provide networking support after graduation!
3. Gaining new skills can help enhance your current career.
Building your skill set and industry knowledge can help you move forward in your current career, and the skills you learn go beyond the obvious. At The Art Institutes, not only can you build your technical and artistic skills, but you can also develop your critical thinking, communication, and teamwork.
Earning your degree can demonstrate to a current employer that you’re serious about your career, and that you’re prepared to take on bigger projects and more responsibility. In the long term, when you apply to new jobs in your field, having a degree can provide you with a competitive edge. Even if the job doesn’t require a degree, your education—along with the quality of your work—may help you stand out among applica

Which of the following is an example of stratified sampling when obtaining a sample of 100 high school students? A. Choosing 100 students at random from a specific grade level at a high school.B. Choosing 100 students sitting in one random section of the cafeteria at a high school.C. Choosing 25 students at random from each of four different grade levels at a high school.D. Choosing 100 students at random from a high school. E. Choosing 100 students at random from an AP Statistics class at a high school.
Answer:
Option C - Choosing 25 students at random from each of four different grade levels at a high school
Step-by-step explanation:
For us to achieve the conditions for a stratified random sample, the target population must be split into different groups which in this case, it's grade levels.
Looking at the 5 options given in the question, Options A, B, D and E are random but they are not truly stratified in their sampling approach. This is because the sample population must be selected at random from each of these groups and it's only option C which is choosing 25 students from each of four different grade levels or groups that reflects that.

Answer:
y=2.4
Step-by-step explanation:
You need to get Y alone so just multiply it with the reciprocal: 1.5/1 on both sides. This cancells out the denominator and just multiplies 1.6 with 1.5 to get 2.4
Look at the graph. On a coordinate plane, a graph increases through (negative 1, 4), levels off at (0, negative 3), and then increases up through (2, 5). Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong? The points (–1, –4), (0, –3), and (2, 5) are not all on the graph. The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1. She miscalculated the rates of change. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.

The total cost C (in dollars) of playing an online game is given by the literal equation C = 30x + 50, where x is the number of months you play the game. Solve the equation for x. How many months do you play the game when you spend $170? $260?
Answer:
4 months and 7 months
Step-by-step explanation:
C = 30x + 50
C is cost so when we spend $170 we can solve for x.
$170 = 30x + 50
170 - 50 = 30x + 50 - 50
170 - 50 = 30x
120 = 30x
120/30 = 30x/30
120/30 = x
4 = x
So he has played 4 months when he spends $170
C is cost so when we spend $260 we can solve for x.
$260 = 30x + 50
260 - 50 = 30x + 50 - 50
260 - 50 = 30x
210 = 30x
210/30 = 30x/30
210/30 = x
7 = x
So he has played 7 months when he spends $260
How do you do letter b?
Answer: 175
Step-by-step explanation:
[tex]g(35)= \int\limits^{35}_0 {f(x)} \, dx =\int\limits^{30}_0 {f(x)} \, dx +\int\limits^{35}_{30} {f(x)} \, dx[/tex]
= 137.5 + 37.5
= 175
Answer:
g(35) = 137.5
Step-by-step explanation:
g(35) = g(30) + [g(35) - g(30)]
g(35) = 100 + 5(15)/2
g(35) = 137.5
state the solutions for the quadratic equation depicted in the graph.
Answer:
(-4,0), (-3,0)
Step-by-step explanation:
The solution of a quadratic equation is simply when the graph crosses the x-axis. This is because at that point, the function will equal 0.
From the graph, we can see that the graph touches the x-axis at x=-4 and x=-3.
Therefore, our solutions for the graphed quadratic is x=-4 and x=-3.

4.5 and 5 are respectively the average of 2sets of number 3, 4, x, y and 2x, y, 4, 3, find the value of x, y
Step-by-step explanation:
4.5 * 4 = 18.
3 + 4 + x + y = 18, x + y = 11.
5 * 4 = 20
2x + y + 4 + 3 = 20, 2x + y = 13
Hence, x = 2 and y = 9.
The toy horse collection contains 10 horses. You purchase the set and then sell 3 horses to Kate. If you only charge the exact price (no tax involved), how much does Kate pay you?
Answer:
three tenths of the original amount
Let's start.
There are 10 horses.
(Buying the set is not important, since it does not affect this scenario.)
You sell three horses to Kate, and you expect her to give you the exact price.
Let's say that 10 horses cost the total (unknown).
10 horses equal the total amount, or 1
10 to 1
Now, you sell 3 of these horses. You must multiply 10 and n to make 3.
10 x n = 3
10x 3/10 = 3
Do the same to the other side.
1 x 3/10 = 3/10
3 to 3/10

Circle B is shown. Line segments C B, D B, and E B are radii and they form 3 congruent angles. What does Arc C D E describe? a minor arc a major arc a semicircle a chord
Answer:
a major arc
Step-by-step explanation:
A circle is the locus of point in which has a given distance from a fixed point (center of the circle).
B is the center of the circle C B, D B, and E B are radii forming 3 congruent angle. Since the sum of angles in a circle is 360°, the 3 line segments form 3 congruent angles of 120° each (360/3).
Therefore the angle measure of Arc C D E = Arc CD + Arc DE = 120° + 120° = 240°
A major arc is an arc greater than a semicircle (> 180°). This means that Arc C D E is a major arc

Examples: Determine if the graph is a function. If it is, state the domain and range.
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.Jan 8, 2019

An explorer is climbing up and rappelling down a series of cliffs and drop-offs. She starts at her base camp, which is on the middle of a mountain. She begins by rappelling down an 82.5-foot drop-off and then climbs a cliff of 30.4 feet. Next she rappels down a 45.5-foot drop-off and then climbs a 25.2-foot cliff.Finally she makes two 45.4-foot climbs. Part A: How far above or below her base camp is the explorer now?
Answer:
162.8 above her camp site she starts at the middle and drops 82.5 and then climbs 30.4 which puts her at 52.1 then by her repelling down another 45.5 drop she then proceeds to climb 25.2 which puts her at 72.4 and if you multiplie 45.4 by 2 it counts for the extra 90.4 drop which then concludes her climb to be bellow her site by 162.8 and the 1st word is supposed to be bellow my bad.
