Answer:
32 school hrs in a week.
Step-by-step explanation:
The reduction percentage =
80 x 0.80 = 64 (hrs)
The distribution =
64/2 = 32hrs
33 x 6= 198
If you need anymore help just let me know!
Step-by-step explanation:
<h3>(1)</h3>
The probability of landing on the color gray ONCE
= 2/7
Since it is spun 35 times, the expected number of times that it lands on a gray will be
(2/7 × 35) = 10 times
<h3>(2)</h3>
The probability of landing on the color black ONCE
= 1/7
Since it is spun 105 times, the expected number of times that it lands on a black will be
(⅐ × 105) = 15 times
The formula is:
Expected value = (Number of spinning)×(probability of landing on a colour)
Answer:
1.) 3/100 , 0.8 , 0.91
2.) 8/100 , 0.2 , 36/100 , 0.44 , 0.5
Step-by-step explanation:
just add 0's after the numbers to get to 100 places, that way you can compare them. add a 0 to 0.5 and you find it's 0.50 .
I'm currently learning it in my math class... i can do some equations... whats the question?
