Answer:
$3450
Step-by-step explanation:
The cost of one computer is the sum of the cost of the parts:
$120 +100 +45 +30 +50 = $345
Then the cost of 10 of them is ...
10 × $345 = $3450 . . . . cost for 10 computers
Answer:
the answer is a 24%
Step-by-step explanation:
35.5 ft is the width of the room
Answer:
a)
And we can find this probability with the complement rule:
b) 
And if we use the z score we got:
Step-by-step explanation:
Let X the random variable that represent the lengths of a population, and for this case we know the distribution for X is given by:
Where
and
Part a
We are interested on this probability
And we can use the z score formula given by:
And using this formula we got:
And we can find this probability with the complement rule:
Part b
For this case we select a sample of n =44 and the new z score formula is given by:

And if we find the z score we got:

And if we use the z score we got:
The percent of change would be -33.3% which would then equal a 33.3% decrease (when decimal is rounded)
what I did was turn 1/4 and 1/2 into decimals to make it easier to solve
