Answer: 72
Step-by-step explanation:
First plug in 7 for x
5(14)
Then multiply
70
Next plug 2 in for y
2(1)
Multiply
2
Lastly, add 70 and 2 together.
72.

Answer:
21.25 seconds
Step-by-step explanation:
In miles per second, the speed of the jet is ...
(720 mi/h)/(3600 s/h) = 1/5 mi/s
The speed of the sound is the same:
(1 mi)/(5 s) = 1/5 mi/s
Then the rate of closure between the airplane and the sound is ...
(1/5 mi/s) +(1/5 mi/s) = 2/5 mi/s
To find the time required to close a gap of 8 1/2 miles, we can use the relation ...
time = distance/speed
time = (8.5 mi)/(0.4 mi/s) = 21.25 s
The pilot will hear the thunder 21.25 seconds after the flash.
The probability of at least 6 failures in 7 trials of a binomial experiment in which the probability of success in any one trial is 9% will be <u>0.000343311 %</u>
<h3>What is the probability?</h3>
Probability is synonymous with possibility. It is concerned with the occurrence of a random event.
Probability can only have a value between 0 and 1. Its simple notion is that something is very likely to occur. It is the proportion of favorable events to the total number of events.
No of failure,n = 7
No of trials,x≥6
A binomial probability is represented as;

Substitute the given data;


Hence,the probability of at least 6 failures in 7 trials of a binomial experiment in which the probability of success in any one trial is 9% will be <u>0.000343311 %</u>

<h3>
Answer: 50</h3>
Explanation:
The original set
{78, 55, 22, 16, 84, 75, 33, 69, 58, 59}
sorts to
{16, 22, 33, 55, 58, 59, 69, 75, 78, 84}
The min and max are 16 and 84 respectively
Midrange = (min + max)/2 = (16+84)/2 = 50
