Step-by-step explanation:
<u> </u>
3.4 or 3.4 repeating (3.4444444444444444444444∞)
and
3.44 rounded to the hundredth
84% of 50 is 42. So if your test was graded out of 50 you would've gotten 42/50. If you multiply 50 by 2 (50x2), you have 100, so then you'd just divide the 84% by 2 so you'd get 42%
Average value is the integral divided by the interval length. Thinking in terms of area, the integral is the total area, and a rectangle with that same area would have width of the interval, height the average value
<span>Int(15 - 15e^(-t/2))[0,4] </span>
<span>= 15t + 30e^(-t/2)[0,4] </span>
<span>= (15*4 + 30/e^2) - (0 + 30) </span>
<span>= 60 + 30/e^2 - 30 </span>
<span>= 30(1 + 1/e^2) </span>
<span>Average value = 7.5(1 + 1/e^2)
So, the answer is A</span>
The answer is -34

Answer:
mean= 4.68
variance= 1.0296
Step-by-step explanation:
mean= n×p
n=6
p=0.78
mean= 6×(0.78)
= 4.68
variance= n×p×(1-p)
= 6 × 0.78×(1-0.78)
= 1.0296
