Answer:
Landers' Mean: 136
Landers' Median: 133
Shakaka's Mean: 136
Shakaka's Median: 133
Step-by-step explanation:
Landers:
Least to greatest: 96, 96, 120, 133, 145, 160, 202
Mean: (96+ 96+ 120+ 133+145+ 160+202)/7 = 136
Median: Since the total numbers is odd, it's just flat out in the middle
133
Shakaka:
Least to greatest: 45, 51, 118, 121, 145, 178, 212, 218
Mean: (45+ 51+ 118+ 121+ 145+ 178+ 212+ 218)/8 = 136
Median:
(121 + 145)/2 = 133
The given dimensions of 9.5, 6, 7, and 6.5 cm gives the following
perimeter and area of the trapezium.
<h3>How can the area and perimeter of the trapezium be found?</h3>
The perimeter of a trapezoid is given as follows;
Perimeter = The sum of the lengths of the sides
Which gives;
Perimeter = 6 + 7 + 6.5 + 9.5 = 29
The perimeter of the trapezoid =<u> 29 cm</u>
The area of the trapezoid is given as follows;
Which gives;
The area of the trapezoid = 49.5 cm²

Answer:
1/4
Step-by-step explanation:
2 outcomes out of a possible 8.
p(HHH or TTT) = 2/8 = 1/4
2 of the 8 slices of pie A were sold (2/8)
3 of the 6 slices of pie B were sold (3/6)
Both of these fractions can be simplified
2/8 --> 1/4
3/6 --> 1/2
In order to add these two fractions, they must have a common denominator. This can be accomplished by multiplying the second fraction by 2
1/2 --> 2/4
Now we can add the two
1/4 + 2/4 = 3/4
Therefore 3/4 of the pie has been sold. In order to find out how much remains, we must subtract the amount that has been sold from the original amount of pie (2)
2 - 3/4 = 1 1/4 = 1.25
5√7 + 12√6 - 10√7 - 5√6
Write it like this:
(12√6 - 5√6) + (5√7 - 10√7),
as the 12 and 5 are both being multiplied by √6, they can be added or subtracted and its the same with 5 and 10, so it becomes:
7√6 - 5√7
You should leave it like this.
