Answer:
Weight of parcel to the nearest whole kilogram = 6 kg
Explanation:
Weight of parcel = 12 lbs 8 oz
1lb = 16 oz also we have 1lb = 454 g
Weight of parcel = 12 lbs 8 oz = 12 + (8/16) lbs = 12.5 lbs
Weight of parcel in g = 12.5*454 = 5675 g
Weight of parcel = 5675 g = 5.675 kg
Weight of parcel to the nearest whole kilogram = 6 kg
Answer:
it is d
Step-by-step explanation:
Basically, solve for n, then find aanother tha is solve for m
8n=-3m+1
divide both sides by 8
n=-3/8m+1/8
and find m
8n=-3m+1
minus 1 both sides
8n-1=-3m
divide both sides by -3
-8/3n+1/3=m
m=-8/3n+1/3
Its the last choice there. Converting that to degrees you get the interval of 90<O<120, which is the only angle that lies in the quadrant in which cosine is negative, which is the second quadrant. Cosine is also negative in the third quadrant, but you don't have choices for the third quadrant.
Answer:
And using the probability mass function we got:
And replacing we got:
Step-by-step explanation:
Let X the random variable of interest "number of students graduated", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
We want to find the following probability:
And using the probability mass function we got:
And replacing we got:
