Total fish = 100
Carp = 30
Number of fish caught = 20
The random variable X follows hyper-geometric distribution.
Mean = 30 *20 / 100 = 600/100 = 6
Variance = 30*20/100 * ((20-1)*(30-1)/100-1 + 1-30*20/100)
Variance = 600/100 * 56/99
Variance = 112/33
Assumptions: Is that X follows hyper-geometric distribution with the given information.
500 x .15 = $75.00.........................
Answer:
a) 3034
b)249
Step-by-step explanation:
jellyb beans: 7*135= 945
choc buds: 9*121=1089
smarties: 12*70=840
liquorice sticks: 32*5=160
a) the total number of sweets: 945 + 1089 + 840 + 160 = 3034
b) the difference between the number of choc buds and the number of smarties: 1089 - 840 = 249

Answer:
Step-by-step explanation:
<u>The billiard cue is 15 cm away from the table</u>
- This refers to coordinates of (15, 0)
<u>The billiard cue touches the table at a point 60 cm off the ground</u>
- This refers to coordinates of (0, 60)
<u>The slope is as per slope formula;</u>
- m = (60 - 0)/(0-15) = 60/ -15 = -4
Thea answer is -4
Answer C. 317.8 would be your answer:) Hope this helps!
