Answer:
1 5/24
Step-by-step explanation:
5/6 + 3/8
LCM of 6&8=24
(5/6)*4 =20/24
(3/8)*3=9/24
20+9/24= 29/24
QRD(Quotuient,Reminder,Divisor)
= 1 5/24
B.
It would be 99%. If you draw the normal distribution curve and plot the mean and standard deviation, it might help you visually.

Answer:
The probability is 0.683
Step-by-step explanation:
To calculate this, we shall be needing to calculate the z-scores of both temperatures
mathematically;
z-score = (x-mean)/SD
From the question mean = 78 and SD = 5
For 73
z-score = (73-78)/5 = -5/5 = -1
For 83
z-score = (83-78)/5 = 5/5 = 1
So the probability we want to calculate is within the following range of z-scores;
P(-1 <z <1 )
Mathematically, this is same as ;
P(z<1) - P(z<-1)
Using the normal distribution table;
P(-1<z<1) = 0.68269 which is approximately 0.683
Hi there,
2400 + 1632 = 4032
3 * 192 = 576
4032 - 576 =>
3532 - 76 =>
3532 + 24 - 76 - 24
3556 - 100
3456
3456 / 576 => 6
Therefore, 6 hours of sprayer work
Hope this helps!
Sincerely,

Both of these conditions must be true in order for the assumption that the binomial distribution is approximately normal. In other words, if 
and 
then we can use a normal distribution to get a good estimate of the binomial distribution. If either np or nq is smaller than 5, then a normal distribution wouldn't be a good model to use.
side note: q = 1-p is the complement of probability p
