Answer:
Exactly 157 inches.
Step-by-step explanation:
It is two times the circumference of the wheel.
<em>C</em> = π<em>d</em> = 3.14(25)(2) = 157 inches
Answer:
143
Step-by-step explanation:
To answer only when the angle is needed to be found where the variable is is when you can add the two angles inside because it is the same as 180-77-66=37 and then finding what 37+__ to make 180 which is 143
A. because when you divide all of the groups, 17.699/11, 41.834/26, 54.706/34, they all get the same answer, 1.609, so they are all proportional, because the relationships stays the same
Hope this helps!
Answer:
Q1 = 30.25 minutes
Q2 = 42.5 minutes
Q3 = 40 minutes
Step-by-step explanation:
Given, In Question
- The stem and leaf diagram (key 2 I 1)
Stem | Leaves
2 | 1 3 5 5 5 8
3 | 1 5 6 7 8 9
4 | 2 3 4 6 6 6 8
5 | 2 2 4 5 7 7 8
- We need to find the quartiles Q1, Q2 and Q3. We know that,
Q1 = (1/4)*(n+1)th value
Q2 = (1/2)*(n+1)th value
Q3 = (3/4)*(n+1)th value
where n is the total number of co-workers 26.
- So,
Q1 = (1/4)*(26+1)th value
Q1 = 6.75th value
we need to count the leaves in the plot starting from the first one until we reach the 6.75th value. So, by counting, we conclude that the 6.75th value lies between the 6th and 7th value i.e. 28 and 31.
Q1 = 28 + (31-28)*0.75
= 28 + 2.25
Q1 = 30.25 minutes
- Now, Q2 = (1/2) * (26+1)th value
= 13.5th value.
From the plot, we find that the 13.5th value lies in the middle of the 13th and 14th values i.e. 42 and 43. So,
Q2 = (42+43)/2
= 85/2
Q2 = 42.5 minutes
-
And, Q3 = (3/4)*(26+1)th value
= 20.25th value
From the plot. we find that the 20.25th value lies somewhere between the 20th and 21st value i.e. 52 and 52. So,
Q3 = 40 + (52-52)*0.25
= 40 + 0
Q3 = 40 minutes
