Answer:
Option 2. 1.4 seconds
Step-by-step explanation:
As we know when a ball is dropped from a height then we apply the formula
Here h = height from the ground
u = initial speed of the ball
t = time taken to reach the ground
g = acceleration due to gravity
Now we put the values of these parameters
h = 30 feet ≅ 9.144 met.
u = 0
g = 9.8 met/sec²
9.144 = 0 + 1/2×9.8×t²
9.144 = 4.9×t²
t² = 9.144÷4.9
t² = 1.87
t = 1.37 ≅ 1.4 seconds
Therefore option 2 is the answer.
Answer:
0.7429
Step-by-step explanation:
Given that Of the 721 students at the college, 299 of them apply for loans when entering graduate school.
So p = proportion of students applying for loans =
Each student is independent of the other and there are two outcomes
Hence out of 45 students the no of students who apply for loans say X is binomial with n =45 and p = 0.415
the probability that more than 16 of them apply for loans
=
=0.7429
Answer:
<h2>The answer is 35</h2>Step-by-step explanation:
Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b
Using Pythagoras theorem we have
a² = b² + c²
where a is the hypotenuse
Substitute the values into the above formula and solve
That's
<h3>We have the final answer as
<h3>35</h3>Hope this helps you
