<u>0.0931</u><u> is the </u><u>probability </u><u>that at least 10 pay in cash.</u>
What is a probability simple definition?
The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
Using binomial distribution with n= 15, and p = 0.40,
P(8<X<12) = P(X=9)+P(X=10) + P(X=11)
= 0.0612+0.0245+0.0074
= 0.0931
Therefore,0.0931 is the probability that at least 10 pay in cash.

Answer:
Annually cumulating interest can be determined by the following formula:
W=P(1+r)^y
r represents the interest rate as a decimal, and P represents the starting amount of money.
Step-by-step explanation:
The correct graph is D.
We can tell this for two reasons. Firstly, you would need a dotted line. Since the equation includes a greater than sign, and not a greater than or equal to sign, it must be dotted.
Then we need to figure out whether to shade above or below the line. The best way to find this is by checking whether the point (0,0) should be shaded.
y + 2 > -3x - 3
0 + 2 > -3(0) - 3
2 > -3 (TRUE)
Since this is a true statement, the side with (0,0) needs to be shaded. Graph D is the only one that has a dotted line and (0,0) shaded.
Hey there!!
Given equation :
... c(x) = 29x + 54.5
<em>In this equation $54.50 is installation fee and this would remain as a constant. ( This value wouldn't change ). </em>
<em>'x' is represented as the number of months. </em>
The total cost or c(x) is given as $344.50
Getting this into equations :
... 344.50 = 29x + 54.5
Subtracting 54.5 on both sides :
... 29x = 290
Dividing by 29 on both sides :
... x = 10
<u><em>Hence, the number of months is 10. </em></u>
Hope my answer helps!!
