Answer:
Sam sliced the pie into 15 equal slices
Step-by-step explanation:
Given : Sam cut a pie into equal slices.There are only three slices left.The angle measure for the three slices is 72 degrees.
We have to determine the number of slices that the Sam cuts.
Sam cuts a pie and pie is in shape of circle therefore total angle measure is 360°.
Since, Given the angle measure for the three slices is 72 degrees.
So, The angle measure for the one slices is
degrees.
Since, Pie is cut into equal slices.
So, measure of each slice must be equal.
So let he cut x slices of pie of 24°
So , total measure of x slices must be equal to 360°
24 · x = 360
x = 15
Thus, Sam sliced the pie into 15 equal slices
<u>Answer:</u>
The correct answer option is: 19, 13, 3, -11, -29.
<u>Step-by-step explanation:</u>
We are given the following explicit formula for an arithmetic sequence:

So to find the first five terms of this sequence, we will substitute the values of
(num here in the given formula:





Therefore, the first five terms of the sequence defined by the explicit formula
are 19, 13, 3, -11, -29.
Answer:
Colin's mean score = 17.10
The new mean is 18.00
Step-by-step explanation:
Given scores: 31, 10, 26, 16, 28, 31, 9, 11, 8, 1
number of terms: 10
mean is calculated by given formula = sum of all the data set/ number of terms in the data set.
mean for the 10 scores = (31+ 10+ 26+ 16+ 28+ 31+ 9+ 11+ 8+ 1 )/10
= 171/10 = 17.1
Colin's mean score = 17.10
____________________________________________
runs scored by Colin in 11th match = 27
number of terms: 11
new mean = new sum /number of terms
new mean = (old sum score + 27)/11 = (171+27)/11
new mean = 198/11 = 18
The new mean is 18.00
