Answer:
160.9 feet
Step-by-step explanation:
The function h(t) = 200 – 17t represents the height of a ball (in feet) dropped from 400 feet after t seconds.
After 2.3 seconds,
h(t) = 200 – 17t
h(2.3) = 200 – (17 X 2.3)
= 200 - 39.1
=160.9 feet
After 2.3 seconds, the ball drops to a height of 160.9 feet.
Answer:
The answer is A.
Step-by-step explanation:
To find the unit rate<span>, divide the numerator and denominator of the given </span>rate<span> by the denominator of the given </span>rate<span>. So in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the </span>unit rate<span>.</span>
35/20 is close to 7/4 so it's 1.75
Answer:
The probability that the European proyect is not succesfull is 0.1
Step-by-step explanation:
Since A and B are independent, A' and B' are independent too.
The probability of B' is P(B')=1-P(B) = 1 - 0.9 = 0.1
