4 of you divide 6 by 1.25 it's 4.8 but for a whole bows it's 4
85 red tickets were added to the box. 100/150 = 2/3
Answer:
A. Infinitely many
Step-by-step explanation:
6x + 35+ 9x = 15 (x + 4) - 25
15x + 35 = 15 x + 60 -25
15x +35= 15x -35
0=0
Answer:
34
Step-by-step explanation:
The mean is calculated as
mean =
let x be the missing frequency, then
Total frequency × midpoint
= (16 × 2) + 7x + (20 × 12) + (10 × 17) = 32 + 7x + 240 + 170 = 442 + 7x
Total frequency = 16 + x + 20 + 10 = 46 + x, thus
= 8.5 ( cross- multiply )
442 + 7x = 8.5(46 + x)
442 + 7x = 391 + 8.5x ( subtract 8.5x from both sides )
442 - 1.5x = 391 ( subtract 442 from both sides )
- 1.5x = - 51 ( divide both sides by - 1.5 )
x = 34
The missing frequency is 34
the LCM of 12 and 15 is 60
