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
$5
The equation is true when we plug 5 in for x. So, x=5 and therefore Ron’s daily allowance is $5.
7(5+5) = 70
7(10) = 70
70 = 70 ✔️
7(10+5) = 70
7(15) = 70
105 = 70 ❌
7(15+5) = 70
7(20) = 70
140 = 70 ❌
7(20+5) = 70
7(25) = 70
175 = 70 ❌
Answer:
4 :)
Step-by-step explanation:
Answer:
obtuse, scalene
Step-by-step explanation:
1 obtuse angle makes the triangle obtuse all sides are different so it would be a scalene triangle
