Answer: the system of inequalities are
x + y ≤ 14
18x + 38y = 342
Step-by-step explanation:
Let x represent the number of iPad chargers sold.
Let y represent the number of keyboards sold.
At the end of the day, he knows he sold a maximum of 14 items. This is expressed as
x + y ≤ 14
If he
charged $18 for each iPad charger (x) and $38 for each keyboard (y) and earned a total of $342, the expression would be
18x + 38y = 342
Answer:
Step-by-step explanation:
18/30 × 100%
= 0.6 × 100%
= 60%
Answer:
300 Burgers
Step-by-step explanation:
Since the question gives us an approximation of 250 burgers, we can round the number to 300. This is only because they had a estimation of 250 and would like to be prepared for the weekend. Being prepared would consist of ordering more than expected to make sure the burgers do not run out.
Answer: 114
Step-by-step explanation:
The value of the denominator in the calculation of the multiple standard error "MSSE' of estimate is given by "n-k-1 " , where n= Total observations , k = total independent variables such that 
Given : A multiple regression analysis is based on 10 independent variables collected from a sample of 125 observations.
i.e. Total observations : n= 125
Total independent variables : k=10
Then, the value of the denominator in the calculation of the multiple standard error of estimate would be (125)-(10)-1 =114
Therefore , the value of the denominator in the calculation of the multiple standard error of estimate = 114 .
We have:
20-minute bike ride
It takes 4 minutes for him to go a kilometer
k is the number of kilometers Garret has already biked
Number of minutes Garret has already biked:
4k
Number of minutes remaining in Garret's ride
20-4k
4(5-k)
Number of kilometers Garret has left to ride
5-k
