308? It seems to be at .7 if an inch so I divided 440 by 10 which was 44, then I multiplied 44 and 7 and I got 308
(3 3/4) / (2/8).....turn mixed number to improper fraction
(15/4) / (2/8)...when dividing fractions, " flip " what u r dividing by, then multiply.
15/4 * 8/2 = 120/8 = 15
Add like terms the answer will be 6a+b+c
Note that there are 24 hours in 1 day, and 60 minutes in 1 hour
First, multiply 25 with 24
25 x 24 = 600
Next, add 600 with 9 hours
600 + 9 = 690
Note that there are 60 minutes in 1 hour. Divide 7 minutes with 60
7/60 = ~0.12 (rounded)
~690.12 hours is your answer
hope this helps
Answer:
1.86
Step-by-step explanation:
Given the following :
X : - - - - 0 - - - - 1 - - - - 2 - - - - - 3 - - - - 4
P(x) - 0.37 - - 0.28 - - 0.22 - - 0.22 - - 0.12
The mean of the distribution can be calculated by evaluated by determining the expected value of the distribution given that the data above is a discrete random variable. The mean value can be deduced multiplying each possible outcome by the probability of it's occurrence.
Summation of [P(x) * X] :
(0.37 * 0) + (0.28 * 1) + (0.22 * 2) + (0.22 * 3) + (0.12 * 4)
= 0 + 0.28 + 0.44 + 0.66 + 0.48
= 1.86
