Answer:
Mean of a grouped data is
Sum of F x/ sum of frequency F
Sum of F = 5 + 15 + 13 + 10 + 7 = 50
to find x find the average of the two classes
That's
0 + 10/2 = 10/2 = 5
10+20/2 = 15
20 + 30 / 2 = 25
30+40 /2 = 35
40+ 50 / 2 = 45
Therefore sum of Fx = 5(5) + 15(15) + 13(25) + 10(35) + 7(45)
= 1240
Therefore
Mean = 1240/50
= 24.8cm
I hope this helps you
Answer:
D
Step-by-step explanation:
7 divided by 3/5
7/1 x 5/3 = 35/3
35/3 = 11 2/3
Answer:
y = 3
Step-by-step explanation:
PQ(5 - 12;-10 + 2) => PQ(-7;-8)
RS(8; y - 10)
because PQ⊥RS
=> (-7).8 - 8(y - 10) = 0
<=> y - 10 = -7
<=> y = 3
