Answer:
Hence safely 9 watermelons can be placed in a single container.
Step-by-step explanation:
Given that the weight (in pounds) of ``medium-size'' watermelons is normally distributed with mean 15 and variance 4.
X = weight in pounds of medium size watermelons is N(15, 2)
Let the water melons stored be n
Then the sample of n has a mean of (15) and std error = 
Capacity = 140
Hence we can say either 8 or 9
If n=9, we have weight = 15*9+1.96*2/3 = 136.40
Hence safely 9 watermelons can be placed in a single container.
100 inches is the correct answer for this question
Answer:
The unit price is 7.79
Step-by-step explanation:
To find the unit price, you should divide what the money is by how many pairs the package has. So for this problem it would mean the equation would be 23.27/3 and the answer is 7.79.
Answer:
k=2
Step-by-step explanation:
We have got a right triangle LNO with sides = m,4 and 8
By Pythagorean theorem
m^2=4^2 +8^2
Or m^2 = 80 ... i
IN triangle NOM, 4^2 +k^2 = l^2
i.e. 16+k^2 = l^2... i
In triangle LNM, m^2+l^2 = (8+k)^2
Substitute for m^2 as 80,
i.e. 80+l^2 = 64+k^2 +16k ... iii
From i, l^2 = 16+k^2
Substitute in iii
80+16+k^2 = 64+k^2 +16k
16k = 32 or k =2
Answer:
Using the combination formula:
Number of combination of r object chosen from the total object i.e n is given by:

As per the statement:
4 candy bars be chosen from a store that sells 30 candy bars
Number of candy bars chosen from a store that sells 30 candy bars(r)= 4
and
Total candy bars(n) = 30
then substitute in the given formula we have;

⇒
⇒
Simplify:
⇒
therefore, 27,405 ways can 4 candy bars be chosen from a store that sells 30 candy bars
