Answer:
y = -1/4(x +4)² +4
Step-by-step explanation:
The equation of a parabola with focus (a, b) and directrix y=d can be written using the form ...
y = 1/(2(b-d))(x -a)² +(b+d)/2
<h3>Application</h3>
We are given (a, b) = (-4, 3) and d=5. Using these values in the above form gives the equation ...
y = 1/(2(3-5))(x -(-4))² +(3+5)/2
y = -1/4(x +4)² +4
Answer:
The second and fourth option
Step-by-step explanation:
In order for two lines to be perpendicular they must intercept each other and their slope must be the opposite inverse; ex:
the negative inverse is 4 (multiplying by -1 and flipping the fraction)
<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.
