P vaires directly with d means
p=kd
7=k3
divide by 3
7/3=k
28=(7/3)d
times 3/7 both sides
84/7=d
12=d
B
Answer:
24
Step-by-step explanation:
Problems at start = 32
-Problems done Friday = ¼ × 32 = <u> 8</u>
Problems still to be done = 24
Andrea had to do 24 problems on Saturday to complete the homework.
840 centimeters ...there 100 centimeters in one meter
Answer:
15, 30, 60, 120, 240, <u>480</u>.
Step-by-step explanation:
You multiply the numbers by 2 to get to the next number.
For example, 15*2 is 30. 30*2 is 60. 60*2 is 120, etc..
Answer:
P(success at first attempt) = 0.1353
Step-by-step explanation:
This question follows poisson distribution. Thus, the formula is;
P(k) = (e^(-G) × (G)k)/k!
where;
G is number of frames generated in one frame transmission time(or frame slot time)
Let's find G.
To do this, we need to find number of frames generated in 1 slot time which is given as 50 ms.
Now, in 1000 ms, the number of frames generated = 50
Thus; number of frames generated in 50 ms is;
G = (50/1000) × 50
G = 2.5
To find the chance of success on the first attempt will be given by;
P(success at first attempt) = P(0) = e^(-G) = e^(-2) = 0.1353
