Step-by-step explanation:
If Q is the midpoint of PR
Then PQ + QR = PR
(6x + 25) + (16 - 3x)
group the same terms and add them
(6x - 3x) + (25 + 16)
Hence PR = (3x + 41)
But to find the value of PR....If Q is the midpoint....then PQ = QR...since they are both half lengths of PR;
; 6x + 25 = 16 - 3x
; 6x + 3x = 16 - 25...;9x = -9
Hence the value of...x = -1
Then substitute the value of x into the equation of PR....3x + 41
;3(-1) + 41
;-3 + 41
Hence PR = 38
we have given an equation 
we need to simplify the given equation.
the distributive property is used here 
if we simplify the terms
we get 
.
For this case we must resolve the following inequality:
Subtracting 8 from both sides of the inequality:
Equal signs are added and the same sign is placed.
Thus, the solution is given by all values of "y" greater than or equal to -20.
Answer:
"y" belongs to the set [-20,∞)
Answer:
The appropriate test to determine if there is an association between being a registered nurse and passing a cultural competency exam among a group of 987 randomly selected hospital employees is a:
Chi-square Test.
Step-by-step explanation:
The Chi-Square Test uses either a diagram (like a scatter plot) or a hypothesis test to show the existence of an association between two variables or statistically demonstrate that a relationship exists between the two variables. Using the computed t-score, the significant association between two categorical variables can be measured and established.
To get the units needed, divide the given number of items needed shown in the above portion of table, with the package size given in the below portion. Then multiply with given prices. Round off the numbers to whole numbers.
Now, money needs to be spent in Quality Groceries-
=$ 168.40
Now, money needs to be spent in Fresh Market-
=$ 180.32
So, the answer is option B.
