Answer: the maximal height is 14.75 units of distance.
Step-by-step explanation:
We want to find the maximum height of the function
h(t) = -16*t^2 + 24*t + 5
In order to find the maximum, we need to find the value of t where the derivate of h(t) is equal to zero, then we evaluate our original function in that time.
The derivate of h(t) (or the vertical velocity) is:
h'(t) = 2*(-16)*t + 24 = -32*t + 24
we want to find the value of such:
0 = -32*t +24
32*t = 24
t = 24/32 = 0.75
Now we evaluate our height function in that value.
h(0.75) = -16*0.75^2 + 25*0.75 + 5 = 14.75 units
Answer:
i think it would be 21 percent he got wrong so if he got 21 percent wrong it would be 79 percent right
Step-by-step explanation:
beacause if it was 10 question it would be 30 percent wrong since its 15 you divide it by 100 which would be 7 and 7 times 3 is 21
sorry if im wrong
Answer:
(D), Predicting.
Step-by-step explanation:
Descriptive statistics involves various methods of collection, analysis , presentation as well as the summarization of a data set. It is involved in understanding the characteristics of the data by measuring the central tendency and measure of dispersion. Thus, it could be concluded that the prediction of the data is not done by the descriptive statistics.
Hence, the correct option is (D), Predicting.
The probability of an event is expressed as

Given:

The probability of drwing two blue balls one after the other is expressed as

For the first draw:

For the second draw, we have only 1 blue ball left out of a total of 6 balls (since a blue ball with drawn earlier).
Thus,

The probability of drawing two blue balls one after the other is evaluted as

The probablity that none of the balls drawn is blue is evaluted as

Hence, the probablity that none of the balls drawn is blue is evaluted as
