anyanavicka [17]
7 hours at 60 mph means 7 hours * 60 mph = 420 miles
He will drive 420 miles per day.
To find the number of days, we divide 3000 miles by 420 miles per day.
3000/420 = 7.14
Since the answer is more than 7 days, he needs at least 8 days for his trip.

djverab [1.8K]

The probability that Andrew has heart disease is 0.9. Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it?

Answer: The probability that Andrew has heart disease =0.9

Also we know that the accuracy rate of test =75\% or 0.75

The given two events are independent.

Therefore, the probability that Andrew has heart disease and the test accurately predicts it =0.9 \times 0.75 =0.675

A football is kicked toward the goal. the height of the ball is modeled by the function h(t) = −16t2 64t, where t equals the tim
diamong [38]

The function H(t) = -16t^2 + 64t exists in a parabola.

The axis of symmetry of a parabola exists at the midpoint between the two real roots.

The roots exist the solutions of H(t) = 0

To estimate the roots equation exists -16t^2 + 64t = 0

Factor t(-16t + 64) = 0

t = 0 and -16t + 64 =0

-16t + 64 = 0

t = 64 / 16 = 4

t = 4

Then the two roots are t = 0 and t = 4, and the axis of symmetry exists

t = (0+4)/2 = 4/2 = 2

<h3>How to estimate the axis of symmetry?</h3>

The axis of symmetry exists at t = 2.

It represents the time at which the ball is at the higher point, the maximum height.

You can find the maximum height replacing t = 2 in the function H(t)

H(t) = -16(2^2) + 64(2)

= 64 feet.

And you can also deduce that the second part of the flight will take 2 seconds, for a total flight time of 4 seconds.

To learn more axis of symmetry refers to:
