Answer:
There will be a total 40 jumps.
Step-by-step explanation:
Every jump a game piece makes measures .
Now, the piece starts at point A = 7 and jumps to the right.
So, the piece will jump over B = 24 after ≈ 20 complete jumps.
Then it switches direction to the left and the piece then stops at point A.
So, there will be a total (20 + 20) = 40 jumps. (Answer)
Answer:
r = 35.18 mm
Step-by-step explanation:
We have,
The diameter of a reamed hole is 70.36 mm.
It is required to find the radius required to draw the hole.
The relation between diameter and radius is given by :
D = 2r
r is radius setting
So, the radius setting used to draw the hole is 35.18 mm.
For the given data set,
12,23,17,20,14,14,18,16,17,18,18
We have to determine the mean, median and mode.
Mean is calculated by the " sum of all the observations divided by the total number of observations".
First of all, let us arrange the numbers in ascending order.
12, 14, 14, 16, 17, 17, 18, 18, 18, 20, 23
Mean =
Mean =
Mean = 17
So, the mean of the data set is 17.
The mode of a set of numbers is the one that occurs most often.
Since, we observe that '18' is a number among the data set which occurs often.
Therefore, mode of the data set is 18.
Now, we will calculate median.
Since there are 11 terms. Since 11 is an odd number.
Median = th observation
=
= 6th observation
From the arranged data set, the 6th observation is 17.
So, the median of the data set is 17.
Hence, Mean = 17
Mode = 18
Median = 17
