Answer:
Step-by-step explanation:
56. 6x = 132
x = 22
57. 2/3 = -8x
-24x = 2
x = -2/24= -1/12
58. 5/11x = 55
5x = 605
x = 121
59. 4/5 = 10/16x
4/5 = 5/8x
23 = 25x
23/25
60. 3 2/3x = 2/9
11/9x = 2/9
11x = 2
x = 2/11
61. 4 4/5x = 1 1/5
24/5x = 6/5
24x = 6
x = 6/24 = 1/4
Answer:
8.5 or 8 1/2.
Step-by-step explanation:
To find the product of 2 5/6 and 3, you can multiply the two numbers together.
2 5/6 x 3 is equal to 8.5, therefore, the product of these two numbers is 8 1/2.
(Hint: Add the three probabilities for either six, seven, or eight boys.)
0.00390625
b. 0.109375
C. 0.03125
d. 0.1445
Answer:
There are many ways to solve this problem, here let's follow the hints
Probability of having exact 6 boys in 8 children:
8C6 x P(boys)^6 x P(girls)^2 = 8C6 x (1/2)^6 x (1/2)^2 =8C6 x (1/2)^8
Probability of having exact 7 boys in 8 children:
8C7 x P(boys)^7 x P(girls)^1 = 8C7 x (1/2)^7 x (1/2)^1 =8C6 x (1/2)^8
Probability of having exact 8 boys in 8 children:
8C8 x P(boys)^8 = 8C8 x (1/2)^8
Add these three, we have the solution
P = (8C6 + 8C7 + 8C8) x (1/2)^8 = (28 + 8 + 1) x (1/2)^8 = 0.1445
=> Option D is correct.
Note: 8C6, 8C7, 8C8 are combination notation.
