A large firm that owns a chain of grocery stores wanted to see if they could increase the average number of patrons who visit by implementing a rewards member program. To test this, they randomly chose half of their 60 locations and started the rewards program only at those locations, while the other half of locations did not receive the rewards program. They also collected information the amount of money spent on these extra customers. Which of these answers represents an element of randomization in this study?
a. use a computer program to select the locations have a rewards program and those that don't
b. have an unbiased person just pick half of the stores to have the rewards program
c. allow store managers to volunteer
Answer:
a. use a computer program to select the locations have a rewards program and those that don't.
Step-by-step explanation:
Randomization refers to an important statistical procedure used to eliminate bias in a study. With randomization, all subjects in the study possess equal chances of being selected. In the study scenario described above, randomly choosing half of their total location to partake in the reward program would involve the use of a technique which isn't liable of introducing bias into the study either deliberately or systematically. The use of store managers or other human in the selection process won't be totally convincing at preventing bias. Hence, a computer program will do.
A large firm that has a chain of the grocery stores has implemented a reward member program to increase the visits of patrons. In order to check this, they test the same at 60 different locations.
They do this by collecting information about the money spent and the number of customers Hence they use a computerized program that allows for asking reward programs and checks those who are eligible for the rewards. The store manager of the chain store has placed such as system in place. This system is simple as it tracks those who have not yet got the rewards by checking their information.Hence the option is A is correct.

Answer:
x = 4
y = 4√3
tan 60° = 1.7321
Step-by-step explanation:
sin 30 = 4/8
0.5 = x/8
x = 4
y² = 8² - 4² = 64 - 16 = 48
y = √48 = 4√3
tan 60° = (4√3)/4 = √3 = 1.7321
find the missing length?
Answer:
16
Step-by-step explanation:
If triangle GFE is similar to triangle RST, using the similarity theorem
RS/RT = GF/EF
Using pythagoras theorem;
RT² = 10² - 6²
RT² =100 - 36
RT² = 64
RT = √64
RT = 8
Recall that RS/RT = GF/EF
10/8 = 20/EF
Cross multiply
10EF = 8 * 20
10EF = 160
EF = 160/10
EF = 16
Hence the missing length is 16

Find the volume (in cubic feet) of a rectangular moving van with length 12 feet, width 6 feet, and height 6 feet.
Answer:
Step-by-step explanation:
V = L * W * H
L = 12
W = 6
H = 6
Volume = 12 * 6 * 6
Volume = 432 cubic feet
Answer:
432 cubic feet
Step-by-step explanation:
To find the volume of a retangular prism or a rectangle you use L x W x H so that would be 12 x 6 x 6 which is 432. So the volume is 432 cubic feet

Maryam has a coupon for 33% off her entire meal of 232.88 what is the discount.
help!
Answer:
$156.03
Step-by-step explanation:
33% = 33/100 = 0.33
First, multiply the total cost with 0.33:
232.88 x 0.33 = ~76.85 (round).
Subtract 76.85 from the original cost ($232.88):
232.88 - 76.85 = 156.03
Maryam's meal will cost $156.03 after the discount.

Someone please help me! Write the equation in standard form!
Answer:
x^2+y^2=6^2
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
where h is the x coordinate of the center, k is the y coordinate of the center, and r is the radius of the circle.
We can see the center is on 0,0, and the radius is 6, so our equation is
(x-0)^2+(y-0)^2=6^2
or
x^2+y^2=6^2
Answer:
[tex] x ^2 + y^2 = 36 [/tex]
Step-by-step explanation:
Center of the circle (h, k) =(0, 0)
Radius of the circle (r) = 6 units
Equation of circle in center radius form is given as:
[tex] (x-h) ^2 + (y-k) ^2 = r^2 [/tex]
[tex] (x-0) ^2 + (y-0) ^2 = (6)^2 [/tex]
[tex] x ^2 + y^2 = 36 [/tex]

7. Construct Arguments Harriet says that it
is not possible to draw a quadrilateral that
is not a trapezoid and not a parallelogram.
Is Harriet correct? Explain why or why not.
Answer:
She is not correct because trapezoid and parallelogram are not the only type of Quadrilaterals.
Step-by-step explanation:
Quadrilaterals are basically 4 sided shapes. Examples include Square, rectangle, rhombus, parallelogram, trapezoid, kite e.t.c.
Now, Harriet is saying that it
is not possible to draw a quadrilateral that is not a trapezoid and not a parallelogram. This statement is wrong because aside trapezoid and parallelogram, I have listed other types of Quadrilaterals above that can be drawn.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
a)
Jesse rode 4 out of 10 miles on his bike.
So , the fraction is A = 4/10 = 0.4
b)
Jesse finished 40 out of 100 math problems.
So , the fraction is A = 40/100 = 0.4
Hence , the equation is A = 0.4
