Answer: the mode is 67.2
Step-by-step explanation:
Given that;
Data Frequency
30 - 34 1
35 - 39 0
40 - 44 3
45 - 49 7
50 - 54 5
55 - 59 10
60 - 64 10
65 - 69 21
70 - 74 12
Mode = ?
we know that mode is the number that has the highest number of appearance of frequency, so in this case, the data group that has the highest frequency (21) is 65 - 69
Lower class boundary of the modal group; L = 65
Frequency of the group before the modal group; Fm-1 = 10
Frequency of the modal group; Fm = 21
Frequency of the group after the modal group; Fm+1 = 12
Group width; G = 4
Now using the formula
Mode = L + [ (Fm - Fm-1) / ( (Fm - Fm-1) + (Fm - Fm+1) ) ] × W
so we substitute
Mode = 65 + [ (21 - 10) / ( (21 - 10) + (21 - 12) ) ] × 4
= 65 + [ 11 / 20] × 4
= 65 + 2.2
= 67.2
Therefore the mode is 67.2
It is not factored completely because it was only factored by 3ab but it could have been factored by 6a²b
6a²b(a+6+8a²)
Step-by-step explanation:
15/36 = 41.6%
because there are 36 total marbles. and 15 of them are either red or yellow.
Answer:7 x -6
Step-by-step explanation: 7 x -6= -42
7 + -6= 1
becasue different signs subtract and keep the sign of the bigger number since the 7 is positive and 6 is negative u subtrac and 7 is bigger than 6 so the answer is gonna be positive. Hope this was helpful <3
So 1st, divide the shape into multiple other shapes.
BTW, sorry if I take long I'm trying to draw the lines on the picture.
Then, the area of a triangle in a=bh(1/2) and for trapezoids, it's (1/2(length of base 1+ length of base 2))height, so, do that for the 2 trapeziods, and do that for the triangles. I got 42.
