a) Tyler ran 0.07 miles farther than Elena in 10 minutes.
b) The paces of each runner are given as follows:
Tyler: 8 minutes per mile.Elena: 8.5 minutes per mile.c) Due to the lower measure of minutes per mile, Tyler ran faster during the run.
What are the equations?For this situation, the input and the output are given as follows:
Input: distance in miles.Output: time in minutes.This situation is represented by a proportional relationship, in this following format:
t = dv.
In which v is the pace in minutes per mile.
From the graph, Tyler runs 1 mile in 8 minutes, hence:
His pace is of 8 minutes per mile.His equation is of y = 8x.Elena's equation is:
y = 8.5x.
Hence her pace is of 8.5 minutes per mile, meaning that she is slower than Tyler, as she takes more time to run a mile.
The distances in 10 minutes are given as follows:
Tyler: 10/8 = 1.25 miles.Elena: 10/8.5 = 1.18 miles.Hence Tyler ran 0.07 miles farther.

what is one important difference between a normal distribution and a t distribution? group of answer choices the t distribution has heavier tails than a normal distribution. the normal distribution has heavier tails than a t distribution. the two distributions have similar tails, it's just that the t distribution can be skewed, while the normal distribution may not be skewed.
Answers
The t distribution has heavier tails than a normal distribution. the normal distribution has heavier tails than a t distribution. the two distributions have similar tails, it's just that the t distribution can be skewed, while the normal distribution may not be skewed.
There are a few important differences between a normal distribution and a t distribution. First, the t distribution has heavier tails than the normal distribution. This means that there is a greater chance of observing extreme values in the t distribution. Second, the t distribution can be skewed, while the normal distribution may not be. This means that the t distribution is more likely to have values that are not evenly distributed around the mean. Finally, the t distribution is more variable than the normal distribution. This means that the t distribution is more likely to have values that are far from the mean.

A medical clinic has a crew of 5, two of which have been infected with a virus althoughthey show no symptoms. If you select two crew members for a task, what is the probability that there is at least one infected person in group assigned for the task.
Answers
P(at least 1 infected person) = 0.7
Explanation:Note that:
Probability = (Number of possible outcomes) / (Number of total outcomes)
The crew members = 5
Number of infected crew members = 2
Number of uninfected crew members = 3
We want to select two crew members for a task out of 5
Number of total outcomes = 5C2 (Selecting 2 out of 5)
Note that:
[tex]nCr=\frac{n!}{(n-r)!r!}[/tex][tex]\begin{gathered} 5C2=\frac{5!}{(5-2)!2!} \\ \\ 5C2=\frac{5!}{3!2!} \\ \\ 5C2=\frac{5\times4\times\cancel{3!}}{\cancel{3!}\times(2\times1)} \\ \\ 5C2=\frac{20}{2} \\ \\ 5C2=10 \end{gathered}[/tex]Number of total outcomes = 10
That is, there are 10 ways of selecting 2 crew members from 5
Number of ways of selecting 1 infected person means how we can select two people out of 5 such that 1 one of them will be infected. This means that we will select 1 from the two infected persons, and select the second one from the 3 uninfected persons
Number of ways of selecting 1 infected persons = 2C1 x 3C1
[tex]\begin{gathered} 2C1=\frac{2!}{(2-1)!1!}=\frac{2!}{1!1!}=\frac{2\times1}{1\times1} \\ 2C1=2 \\ \\ 3C1=\frac{3!}{(3-1)!1!}=\frac{3!}{2!1!}=\frac{3\times2\times1}{2\times1\times1}=\frac{6}{2} \\ 3C1=3 \end{gathered}[/tex]Number of ways of selecting 1 infected persons = 2 x 3
Number of ways of selecting 1 infected persons = 6
Number of ways of selecting 2 infected persons = 2C2
[tex]2C2=\frac{2!}{(2-2)!2!}=\frac{2!}{2!}=1[/tex]Number of ways of selecting 2 infected persons = 1 way
Probability of selecting 1 infected person = 6/10 = 0.6
Probability of selecting 2 infected person = 1/10 = 0.1
P(at least 1 infected person) = P(1 infected person) + P(2 infected persons)
P(at least 1 infected person) = 0.6 + 0.1
P(at least 1 infected person) = 0.7

Matthew drives 54 miles per hour. Benjamin drives 47 miles per hour. They started at the same spot, and drove in opposite directions. Aftersome time, they were 1272.6 miles apart. How much time has passed?After _____ hours, Matthew and Benjamin were 1272.6 miles apart.
Answers
Solution:
Matthew and Benjamin start from the same spot and drives in opposite directions.
Given:
[tex]\begin{gathered} \text{Matthew's sp}eed=54mph \\ \text{Benjamin's sp}eed=47mph \\ \text{Distance apart after time (t)=1272.6miles} \end{gathered}[/tex]The formula for speed is given by;
[tex]\begin{gathered} \text{Speed}=\frac{dis\tan ce}{\text{time}} \\ \text{Hence, } \\ \text{distance}=\text{speed}\times time \end{gathered}[/tex]During the journey, they used the same time but moved at different speeds, hence, they will have different distances.
Let the time both used be represented by t
Let Matthew's distance be represented by m
Let Benjamin's distance be represented by b
Thus,
Matthew's distance is calculated below;
[tex]\begin{gathered} \text{distance}=\text{speed}\times time \\ m=54\times t \\ m=54t \end{gathered}[/tex]Benjamin's distance is calculated below;
[tex]\begin{gathered} \text{distance}=\text{speed}\times time \\ b=47\times t \\ b=47t \end{gathered}[/tex]The distance covered by the two of them in opposite directions is their distance apart from the starting point.
Hence,
[tex]m+b=1272.6[/tex][tex]\begin{gathered} 57t+47t=1272.6 \\ 101t=1272.6 \\ \text{Dividing both sides by 101 to get the time t,} \\ t=\frac{1272.6}{101} \\ t=12.6\text{hrs} \end{gathered}[/tex]Therefore, after 12.6hours, Matthew and Benjamin were 1272.6 miles apart.

A line passes through the point (4, 8) and has a slope of 3/2.
Write an equation in slope-intercept form for this line.
Answers
Answer:
y=1.5x+2
Step-by-step explanation:
The equation for a line in slope-intercept form is written as y=mx+c where m is the slope and cis the y-intercept.
We know the slope is 3/2 or 1.5, so we can write
y=1.5x+c
We know the line contains the point (4,8), so we can sub this in to find c:
8=1.5(4)+c
8=6+c
c=2
Having found m and c, we can write the equation:
y=1.5x+2
Answer: [tex]\text{y}=\frac{3}{2}\text{x}+2\\\\[/tex]
This is the same as writing y = (3/2)x + 2
=====================================================
Work Shown:
[tex]\text{y}-\text{y}_1=\text{m}\left(\text{x}-\text{x}_1\right)\\\\\text{y}-8=\frac{3}{2}\left(\text{x}-4\right)\\\\\text{y}-8=\frac{3}{2}\text{x}+\frac{3}{2}(-4)\\\\\text{y}-8=\frac{3}{2}\text{x}-6\\\\\text{y}=\frac{3}{2}\text{x}-6+8\\\\\text{y}=\frac{3}{2}\text{x}+2\\\\[/tex]
I used point-slope form as the first step. The 'm' is the slope, and [tex](x_1,y_1) = (4,8)[/tex] is the point on the line.
The final step shows us the line has a y intercept of b = 2, which is at the location (0,2).
To graph this, draw a straight line through (0,2) and (4,8)
--------------
Check:
Plug x = 4 into the equation we found. We should arrive at y = 8.
[tex]\text{y}=\frac{3}{2}\text{x}+2\\\\\text{y}=\frac{3}{2}*4+2\\\\\text{y}=\frac{12}{2}+2\\\\\text{y}=6+2\\\\\text{y}=8\\\\[/tex]
This confirms (4,8) is indeed on this line and confirms the answer is correct.

The owner of Rockport Florist is assembling flower arrangements for Valentine's Day. This morning, she assembled 11 small arrangements and 1 large arrangement, which took her a total of 62 minutes. After lunch, she arranged 12 small arrangements and 1 large arrangement, which took 67 minutes. How long does it take to assemble each type?
Answers
To solve this, we need to write a system of equations.
We know that it took her 62 minutes to assemble 11 small and 1 large.
Let's call the small arrangements S, and the large L.
Then:
[tex]11S+L=62[/tex]After lunch, she did 12 small and 1 large in 67 minutes. Then:
[tex]12S+L=67[/tex]Now we have the system of equations:
[tex]\begin{cases}11S+L=62 \\ 12S+L=67\end{cases}[/tex]To solve by elimination, we need to eliminate one unknown by adding or substracting the two equations. If we rest the first equation to the second equation:
[tex](12S+L)-(11S+L)=67-62[/tex]Now we can solve:
[tex]\begin{gathered} 12S-11S+L-L=65-62 \\ S=5 \end{gathered}[/tex]To make a small arrangement takes her 5 minutes. Now we can go back to the first equation and replace S = 5:
[tex]\begin{cases}11S+L=62 \\ S=5\end{cases}\Rightarrow11\cdot5+L=62[/tex]And solve for L:
[tex]\begin{gathered} 55+L=62 \\ L=62-55 \\ L=7 \end{gathered}[/tex]Then it takes her 7 minutes to make a large arrangement.

The required transformed function is given by, g(x) = 5/(x-2) + 6
Given the parent function is, f(x) = 1/x
Now if we vertically stretched the function by a factor 5 units then the function becomes,
g(x) = 5/x
Again if we shifted to the right to 2 units then the function becomes,
g(x) = 5/(x-2)
Further if we shift up to 6 units then the function transformed to,
g(x) = 5/(x-2) + 6
Hence the ultimate transformed function is, g(x) = 5/(x-2) + 6.
