First find X by subtracting 9.8 from 14.7
X should equal 4.9
than fill in the equation for x
8(4.9-3.7)
you then subtract in the parenthasis
getting the answer of 1.2
finally multiply 1.2x8
Your final answer is 9.6
The first thing we must do in this type of problem is first to name the variables that we are going to use to write the inequality.
We have then:
b = the weight of books on the shelf.
The inequality is:
b <= 95
answer:
An inequality to represent the situation is
b <= 95
<span>There are 720 distinct permutations, or ways in which things can be rearranged. The formula is n!=n * (n-1) * (n-2) * (n-3) * (n-4) * (n-5) * (n-6) or, 6!=6*5*4*3*2*1=720. Therefore, the six basketball players can listed in 720 ways on the program.</span>
Answer:
The standard deviation for the mean weigth of Salmon is 2/3 lbs for restaurants, 2/7 lbs for grocery stores and 1/4 lbs for discount order stores.
Step-by-step explanation:
The mean sample of the sum of n random variables is
If 
are indentically distributed and independent, like in the situation of the problem, then the variance of 
will be the sum of the variances, in other words, it will be n times the variance of 
.
However if we multiply this mean by 1/n (in other words, divide by n), then we have to divide the variance by 1/n², thus 
and as a result, the standard deviation of 
is the standard deviation of divided by 
.
Since the standard deviation of the weigth of a Salmon is 2 lbs, then the standard deviations for the mean weigth will be:
- Restaurants: We have boxes with 9 salmon each, so it will be
- Grocery stores: Each carton has 49 salmon, thus the standard deviation is
- Discount outlet stores: Each pallet has 64 salmon, as a result, the standard deviation is
We conclude that de standard deivation of the mean weigth of salmon of the types of shipment given is: 2/3 lbs for restaurants, 2/7 lbs for grocery stores and 1/4 lbs for discount outlet stores.
Answer:
Let n and n+4 be the numbers. Then:
n² + 3(n+4)=66
n²+3n-54=0
(n+9)(n-6)=0
n=6 or -9
n+4=10
Assuming positive integers only, the numbers are 6 and 10…..
Step-by-step explanation:
