Answer:
0.25 k miles
Step-by-step explanation:
15 minutes =1/4 of an hour
Distance= speed*time= k (1/4)= (1/4) k= 0.25 k miles
The distance is the multiplication of speed and time thus the speed covered in 15 minutes with a speed of k miles per hour will be k/4.
What is velocity?Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
Average velocity = total distance / total time taken
Units of velocity are given by ⇒ meter/second
As per the given,
Number of miles covered = m
Speed = k miles per hour.
1 hour = 60 mint
15 mint = 1/4 hour.
Since, speed = distance/time
Distance = speed × time
Distance = k × 1/4 = k/4
Hence "The distance is the multiplication of speed and time thus the speed covered in 15 minutes with a speed of k miles per hour will be k/4".

Which model completes this equation?
= ?
Answer:
The model that has 2 blue slices filled.
Explanation:
In the first circle, there are 4/10 blue slices filled. In the second circle, there are 2/10 purple slices filled.
4/10 - 2/10 = 2/10
Therefore, your answer is 2/10 shaded blue.

The pet shop decides to run their analysis as a regression, and finds an error mean sum of squares of 6.8, and an F-statistic of 6.2. What is the between-group variance?
Answer:
42.16
Step-by-step explanation:
Calculation for the between-group variance
Using this formula
The between-group variance=Error mean sum of squares *F - statistic
Let plug in the formula
The between-group variance = 6.8 * 6.2
The between-group variance= 42.16
Therefore the The between-group variance will be 42.16

What type of number cannot be written as a fraction p/q , where p and q are integers and q is not equal to zero
9514 1404 393
Answer:
irrational
Step-by-step explanation:
A number that can be written as the ratio of two integers is called a "rational" number. If it cannot be written that way, it is called an "irrational" number
Irrational numbers cannot be written as a fraction of p/q.
Rational numbers can be written as a fraction of p/q.
Mr. Robin and Mr. Donovan both are teachers and compare the mean score on thier classes math quizzes to determine who taught the lessons better. The quiz scores for each class are below. Mr. Robin: 55%, 60%, 75%, 85%, 80%, 100%, 100%, 95%, 65%, 90% Mr. Donovan: 100%, 100%, 95%, 65%, 70%, 70%, 60%, 65%, 55%, 50% Mr. Robin says that he is the better teacher. Is he correct? Why or Why not? Explain how you know using math language and your knowledge of means/averages.
Answer:
yes i think
Step-by-step explanation
because Mr. R has many better percentages than Mr. D.
for example, Mr. D., you would expect, has less better grades from his class than Mr. R.
but i think they want to confuse you so Mr Robin is greater
then again this is a guess off my knowledge

You and a friend are playing a best-of-three series (first to win 2 games wins the series). You are a stronger player and have a 0.68 chance of winning each game. Both you and your friend play better after winning a game. If you win a game, your chance of winning the next game is 0.81. If your friend wins a game, the chance they win the next game is 0.73. What is the probability you win the series
Answer and Step-by-step explanation:
Given that probability of you winning each game = 0.68
And probability of you winning next game = 0.81
Your friend's chance of winning/you losing would be = 1-0.68= 0.32
also his chance of winning next game = 0.73
To find probability that you would win the series given that you need to win two games to win the series
= probability that you win first game and second game+ probability that you win first game, lose second game and win third game + probability that you lose first game, win second game and win third game
= 0.68*0.81+0.68*0.32*0.68+0.32*0.68*0.81
=0.8750
Therefore probability that you would win the series = 0.8750
Note: here we found the probability of winning by adding(or) up the three possible combinations that would result in a win
