Answer:
A) 3.6 in.
Step-by-step explanation:
36/10 = 3.6
Answer:
n = 6
x = 3
p = 0.32
q = 0.68
Step-by-step explanation:
Given:
32% are comfortable having drones deliver their purchases.
Suppose we are to find the probability that when 6 consumers are randomly selected, exactly 3 of them are comfortable with delivery by drones.
Required:
Find n, x, p, and q.
i) n represents the sample size. Here 6 consumers are selected randomly, therefore the sample size here is 6.
Thus, n = 6
ii) x represents the sample mean or number of successes. Since 3 consumers out of the selected 6 are comfortable with delivery by drones, the sample mean here is 3.
Thus, x = 3
iii) p represents population proportion or probability of success. Here population proportion(success probability) is 32% ≈ 0.32.
Thus, p = 0.32
iv) q represents probability of failure. To find probability of failure, use the formula:
1 - p
Thus,
1 - 0.32 = 0.68
q = 0.68
i would think it goes to them or like the bank
For this sys of equations, like all, we first have to solve for y or x in either equation
In this case, lets solve for y in the 2nd equation
-2x+3y=9
add 2x to both sides
3y=9+2x
divide 3 on both sides
y=2/3(x) + 3
now plug in y for the first equation
2x-5(2/3x)+3/11
simplify
-4/3(x) + 3=11
subtract 3 from both sides
-4/3x=8
multiply 3/4 on both sides
x= -6
now plug in x for either equation, lets do the first one again
2 (-6)-5y=11
-5y-12=11
add twelve to both sides
-5y=23
divide
y=-23/5
your final answer would be
x=-6, y=-23/5
