Answer:
equation:x*1/5=9/20
answer=9/4
Step-by-step explanation:
9/20÷1/5=9/20×5/1 in word form you multiply 9/20 by its reciprocal.
first you want to simplify and change 9/20 to 9/4 and change 5/1 to 1/1 and then multiply to get 9/4
The mean is the sum of the given data divided by the number of the data
So we will add the data first
The sum of the times = 10 + 5 + 6 + 8 + 13 + 9 + 11 = 62
The number of students = 7
The mean is
Round it to the nearest tenth, then
The mean = 8.9
The mean travel time is 8.9
Answer:
K
Step-by-step explanation:
techincally, I don't know if I am right, but there is more than one answer. The boundries/restrictions of what length DF could be are 2.477 < x < 8.477
54 55 59 61 61 62 68 70 72
First put your numbers in order from least to greatest. This shows your minimum is 54 and maximum is 72.
In the middle of the data set is 61.
54 55 59 61. 61. 62 68 70 72
To find the first qaurtile only use the numbers before rhe median (54 55 59 61) and find the median of that. Since 55 and 59 are both in the middle add them both and divide by two to find the middle lf those two numbers. You should get 57. So 57 is the first quartile.
Do the same steps with the numbers after the meadian for your third quartile. You should get 69 as your answer for the third quartile.
Answer:
The discriminant is equal to zero
Step-by-step explanation:
If x=6 is the only x-intercept of the graph of a quadratic equation, the it means the quadratic equation has a repeated root.
When a quadratic equation has a repeated root, it means its discriminant is zero.
This means that
