Inspectors for a hospital chain with multiple locations randomly select some of their locations for a cleanliness check of their operating rooms. The inspectors check every operating room in the hospitals that were chosen. What sampling method was used?
Answer:
Cluster Random Sample
Step-by-step explanation:
The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.
Sampling method is the method where the subset of an overall population is selected.
The sampling method used was cluster sampling
From the question, we understand that:
The inspectors select some locationsThen all selected locations was checkedThe above illustrates cluster sampling.
This is so because, cluster sampling involves breaking down a population into smaller size.
In this case, the smaller size are the locations that were selected.

Write an equation that you can use to find the number of refills Keith bought. A restaurant sells a coffee refill mug for $6.75. Each refill costs $1.25. Last month Keith spent $31.75 on a mug and refills. (use x for your variable and do not use $ in your answer) *
Answer:
6.75+1.25x=31.75
Step-by-step explanation:
let x be the number of refils
also given is that the cost of one refill is $1.25
hence the total refil will be 1.25x
given that the cost of a mug is $6.75
6.75+1.25x=31.75
therefore the expression that can be used to solve for the number of refills is
6.75+1.25x=31.75

What is Inequality?Inequalities are mathematical formulas in which neither side is equal.
As per the given data:
We are given two inequalities, and we have to find out whether the points that are given in the options are satisfying the solution set of the given inequalities or not.
The inequalities are as follows:
x + y > 2
4x + y ≥ -1
For option (A). (2, 0)
Substituting the points in the given inequalities.
2 > 2 and 8 ≥ -1
Hence, this is incorrect.
For option (B). (0, 2)
Substituting the points in the given inequalities.
2 > 2 and 2 ≥ -1
Hence, this is incorrect.
For option (C). (0, 3)
Substituting the points in the given inequalities.
3 > 2 and 3 ≥ -1
Hence, this is correct.
For option (D). (0, -1)
Substituting the points in the given inequalities.
-1 > 2 and -1 ≥ -1

What is the sum of zeros in this equation (m-10)(8m-1)=0? Ente4 your ancwer as a fraction. PLSSS I RLLYYY NEEDD HELPP
Answer:
10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]
Step-by-step explanation:
Given
(m - 10)(8m - 1) = 0
Equate each factor to zero and solve for m
m - 10 = 0 ⇒ m = 10
8m - 1 = 0 ⇒ 8m = 1 ⇒ m = [tex]\frac{1}{8}[/tex]
Thus sum of roots = 10 + [tex]\frac{1}{8}[/tex] = 10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]

The sum of five consecutive even integers is 220. Find the middle value of the five consecutive integers.
Answer:
44Step-by-step explanation:
If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:
220:5 = 44
Of course you can find them to be sure:
Consecutive even integers increase by 2.
So if 2x is the smallest of them (x is an integer), then the numbers are:
2x, 2x+2, 2x+4, 2x+6, 2x+8
So their sum: 10x+20
10x + 20 = 220 ⇒ 10x = 200 ⇒ 2x = 40
So the numbers are: 40, 42, 44, 46, 48

44

How many years will it takes an investment of 3000$ to amount to 5,000 if money is invested at 4.1% compounded monthly
Answer:
1.66
Step-by-step explanation:
The years needed to make $3000 to $5000 is 12.5.
What is compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, an investment of $3000 to amount to 5,000 if money is invested at 4.1% compounded monthly
A = P(1+r/12)^12t
5000 = 3000(1+0.041/12)^12t
5/3 = (1.0034)^12t
Taking log both sides,
log5/3 = 12tlog(1.0034)
0.221 = 12t0.00147
12t = 150.34
t = 12.5
Hence, required years are 12.5.

You decide to go to the candy store in the mall. You arrive at the store with $25 and then purchase 3 candy bars. You then buy a giant candy snake for $12.50. When you leave, you have $8.75 left in your wallet. How much did each candy bar cost? Write the equation to represent the scenario. 8.75 - x - 12.50 = 25.00 25.00 - 3x - 12.50 = 8.75 25.00 - 3x - 8.75 = 12.50 25.00x - 12.50 = 8.75
Answer:
The cost of a candy is $1.25Step-by-step explanation:
given the total amount at hand is $25
let the price of candy be x
then the cost of 3 candy will be 3x
the cost of a candy snake is $12.50.
balance at hand after the end of buying $8.75
the total expenses summed up must equal the initial amount at hand which is $25
the expression for the scenario is 3x+12.5+8.75=25
3x+21.25=25
3x=25-21.25
3x=3.75
x=3.75/3
x=$1.25
The cost of a candy is $1.25
