Answer:
1) both
2) Yes. It is appropriate to conclude that the health of the student affects ability to taste.
Step-by-step explanation:
Random Sampling is done when each element of the sample has equal probability of being chosen. In both the samples of healthy and runny nose students each student has equal probability of being tested.
Random Assignment is one in which there is a control group and experimental group. The control group contains all the participants and each participant has the equal probability of being placed in the experimental group. For example in this experiment each student has equal probability of being tested with the given chocolate bar.
2) Yes. It is appropriate to conclude that the health of the student affects ability to taste.
the probability of success in healthy student is 78/154= 0.5065 = 50.65%
the probability of success in runny nose student is 44/118= 0.3729 = 37.29%
From this we see the probability of success is more in healthy students as compared to runny nose students
50.65> 37.29
Therefore it is appropriate to conclude that the health of the student affects ability to taste.

if one point is located at (-5,3) and another point is located at (7,-4). find the distance between the points. round to the nearest tenth.
Answer:
13.9
Step-by-step explanation:
Use the distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\[/tex]
The square root of 193 rounded to the nearest tenth is 13.9.
How can you use tables, graphs and equations to compare functions
Answer:
A graph is a chart or drawing that shows the relationship between changing things.
- They are a diagram displaying the relationship between numbers or amounts.
- A graph is one of the easiest ways to compare numbers.
- A graph or chart is used to present facts in visual form.
- They are a drawing that displays the relative sizes of numerical quantities.
- Graphs can be used to illustrate many types of data.
- They should be used to make facts clearer and more understandable.
- it shows trends over time.
- Forceful -- Emphasizes main point
- Convincing -- proves a point, see and hear
- Compact way to convey information
- More interesting than just talk or print
- Quick way for the audience to visualize what you are saying -- numbers trends up or down
- To bring facts to life
- To show and compare relationships
- To show and compare changes
- They are much easier to understand then a large
table of numbers
- without
the need to understand what each and every number in a table means.
They help you visually see the difference between two or more values.

2. Some kids went on a bike ride. The ride was six hours long and the kids traveled 54 miles. For part of the ride they biked at a speed of 7 mph and for part of the ride they biked at a speed of 11 mph. For how long did they bike at the first speed, and for how long at the other speed?
3. I left Boston for Washington, DC, at 7:00 am. At first, my speed was 55 mph; then it was 75 mph. I traveled 630 miles in 10 hours. At what time did I begin to drive faster?
Thanks!
Answer: 1= 41
2= 3 hours biking at the other speed.
3= We began to drive at 75 mph at 1:00 p.m
Step-by-step explanation:
3= x/55 + (630 - x)/75 = 10
75x + 55 * (630 - x) = 41,250 (4,125 as Lowest common multiple)
75x + 34,650 - 55x = 41,250
20x = 41,250 - 34,650 (Subtracting 34,650 at both sides)
20x = 6,600
x = 6,600/20
x = 330 ⇒ 630 - x = 300
Time we drove at 55 mph = 330/55 = 6 hours
Time we drove at 75 mph = 300/75 = 4 hours
We began to drive at 75 mph at 1:00 p.m. (7 am + 6 hours)
hope this helps :)

Consider the relationship 7r+2t=7. a. Write the relationship as a function r=f(t).
Answer: r = 2/7 -t
Step-by-step explanation: solve r from equation
7r = 2-7t l:7. r = 2/7 - t
The relationship as a function r=f(t) is [tex]\rm f(t)=\dfrac{7-2t}{7}\\\\[/tex].
What is the equation?In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
Consider the relationship;
7r+2t=7
Substitute r = f(t) in the equation
[tex]\rm 7r+2t=7\\\\7f(t)+2t=7\\\\ 7f(t)=7-2t\\\\f(t)=\dfrac{7-2t}{7}\\\\[/tex]
Hence, the relationship as a function r=f(t) is [tex]\rm f(t)=\dfrac{7-2t}{7}\\\\[/tex].
