Answer: h(3.2) =753.44 units represents the height after 3.2 seconds .
Step-by-step explanation:
Since we have given that the function
where t represents the time in seconds .
And we need to find the value of h(3.2)
So,
we just substitute the value of 3.2 in the function,
So, after 3.2 seconds the height will be 753.44 units.
Given, in the spinner 8 equal sectors, numbered 1 to 8.
So total numbers = 8.
Let, the probability of spinning a 3 is P(Three) and spinning an 8 is P(Eight).
Now we know that, probability of an event E is
P(E) = (number of outcomes in the event)/ (total number of possible outcomes).
So here number of outcomes for spinning a 3 is 1 and we have got total outcomes = 8.
So P(Three) =
Similarly, P(Eight) =
Probability of spinning a 3 or an 8 = P(Three) + P(Eight)
=
As the denominator is same we can add the numerator.
=
=
Now we have to simplify the fraction by dividing the numerator and denominator by a common factor of them.
The common factor of 2 and 8 is 2. So by dividing them we will get,
=
We have got the required answer.
The probability of spinning a 3 or an 8 is
Answer:
μ = 1.877
Step-by-step explanation:
Data provided in the question:
Number of data samples, n = 10
Data: 2.18, 2.03, 1.56, 1.09, 1.56 ,2.28 ,1.62 ,2.02 ,2.11 ,2.32
Now,
Mean is calculated using the formula as:
Mean, μ =
