Answer: 0.7515
Step-by-step explanation:
Binomial probability formula:
, where
n = total number of trials.
p= probability of success in each trial.
x= Number of successes.
Let x be a binomial variable that represents the number of jurors come to just decision.
p= 0.65
n= 10
Required probability=
Hence, the probability more than half come to a just decision = 0.7515
Well you would have to fill in the bank so it would be 4000 and the answer would be 11,000 <span />
Answer:
Step-by-step explanation:
Given
$x per adult
$8 per student
Population:
Required
Determine the equation and solve for x
The system can be analyzed as thus:
The cost for 4 adults is: 4 * x
The cost for 1 students is: 8 * 1
Total Amount is: 48
From the analysis above, the equation is:
Subtract 8 from both sides
Solve for x
Answer:
C. 560
Step-by-step explanation:
50% is one half, so there is another half of 280. 280*2=560
I don't think you can give medals on this site, but ok
a way to simplify it is to solve for y
x+2y=8
minus x both sides
2y=8-x
divide both sides by 2
y=4-x/2
(x,y)
just sub points in (sub x values for x and see if you get the coresponding y value)
example
point (8,0)
x=8 and the resulting y should eual 0
y=4-x/2
y=4-8/2
y=4-4
y=0
yes
A. (8,0) works, (6,1) works, (4,2) works
B. (2,4) doesn't work, so this option is wrong
C. (0,8) doesn't work, so this option is wrong
D. (0,8) still , doesn't work, so this option is wrong
answer is A
