A large supermarket chain was interested in seeing if they could increase their holiday sales by starting their Black Friday sales 2 hours earlier than normal. To test this, they randomly selected half of their 500 stores and told them to start their sales at the new starting time, while the other half of the stores would start at the standard starting time. Which of these answers represents an element of replication in this study?
a. they randomly selected half
b. their 500 stores
c. while the other half of the stores would start at the standard starting time
d. 250 stores
Answer:
wow hold on BTW I LIKE YOUR CUG
The element of replication in the study is option b, their 500 stores.
What is Replication in Statistics?Replication in statistics id defined as that repeating an experiment so that the variability if any existing in the event can be noticed.
Replicate is termed as each of the repetition.
Given that,
A large supermarket chain was interested in seeing if they could increase their holiday sales by starting their Black Friday sales 2 hours earlier than normal.
To test this, they randomly selected half of their 500 stores and told them to start their sales at the new starting time, while the other half of the stores would start at the standard starting time.
So here the replication is the repetition of the same experiment by 500 stores.
So the element of replication is 500 stores.
Hence 500 stores is the element of replication.

a helicopter is bought for 5 million.its value depreciated by 7%each year .how many years wil it take for value to halve
Answer:
Number of year = 9.5 year
Step-by-step explanation:
Given:
Initial value[Cost price] = $5,000,000
Depreciation rate[r] = 7% = 0.07
Final value[After depreciation cost] = 5,000,000 / 2 = $2,500,000
Find:
Number of year[After half value]
Computation:
A = p[1-R]ⁿ
Final value = Initial value[1-r]ⁿ
2,500,000 = 5,000,000[1-0.07]ⁿ
0.5 = [0.93]ⁿ
Number of year = 9.5 year

A radioactive substance has a continuous decay rate of 0.056 per minute. How many grams of a 120 gram sample will remain radioactive after 40 minutes? Round the answer to the nearest tenth of a gram, and do not include the unit in your answer.
Answer:
The mass of the radioactive sample after 40 minutes is 12.8 g.
Step-by-step explanation:
The mass of the sample can be found by using the exponential decay equation:
[tex] N_{t} = N_{0}e^{-\lambda t} [/tex]
Where:
N(t): is the amount of the sample at time t =?
N₀: is the initial quantity of the sample = 120 g
t = 40 min
λ: is the decay constant = 0.056 min⁻¹
Hence, the mass of the sample after 40 min is:
[tex] N_{t} = N_{0}e^{-\lambda t} = 120g*e^{-0.056min^{-1}*40 min} = 12.8 g [/tex]
Therefore, the mass of the radioactive sample after 40 minutes is 12.8 g.

Exercise 11.1.2: Find the next permutation in lexicographic order. About For each permutation of {1, 2, 3, 4, 5, 6, 7}, give the next largest permutation or indicate that the permutation is the last one in lexicographic order. (a) (1, 2, 3, 4, 5, 6, 7) (b) (7, 6, 5, 4, 3, 2, 1) (c) (1, 7, 6, 4, 2, 3, 5) (d) (3, 7, 6, 5, 4, 2, 1) (e) (5, 4, 7, 6, 3, 2, 1)
Solution :
A permutation in the field of mathematics may be defined as the arrangement of its members into a linear order or a sequence. However, if a set is already being ordered, then it is the rearrangement of the elements of the set.
In the context, the next largest permutation set is :
a). (1,2,3,4,5,6,7)
b). The given permutation is the last one in the lexicographic order.
c). (1,7,6,4,2,5,3)
d). (4,1,2,3,5,6,7)
e). (5,6,7,4,3,2,1)
The next permutation in lexicographic order will be (5,6,7,4,3,2,1).
What is a permutation?
It should be noted that a permutation in the field of mathematics where there are several possible ways in which numbers or things can be ordered or arranged.
When applied to numbers, the lexicographic order is increasing numerical order. This is an increasing numerical order from left to right). For example, the permutations of {1,2,3} in lexicographic order are 123, 132, 213, 231, 312, and 321
In the context, the next largest permutation set is (5,6,7,4,3,2,1).

tan(3)=a/4960
Answer:
[tex]\boxed {\boxed {\sf 260 \ feet}}[/tex]
Step-by-step explanation:
We are asked to find the driver's altitude increase. The increase in altitude is also the height of the triangle, which is labeled a.
Since this is a right triangle (signified by the small square representing a 90 degree angle), we can use trigonometry. The three trigonometric ratios are:
sinθ=opposite/hypotenuse cosθ= adjacent/hypotenuse tanθ=opposite/adjacentThe angle (θ) given is 3 degrees. Side a is opposite this angle and the side measuring 4,960 feet is the hypotenuse because it is opposite the right angle. Therefore, we use sine.
[tex]sin \theta= \frac {opposite}{hypotenuse}[/tex]
[tex]sin 3= \frac {a}{4960}[/tex]
We are solving for a, so we must isolate the variable. It is being divided by 4960 and the inverse of division is multiplication. Multiply both sides by 4960.
[tex]4960*sin 3= \frac {a}{4960}*4960[/tex]
[tex]4960*0.05233595624= a[/tex]
[tex]259.586343=a[/tex]
Round to the nearest whole number. The 5 in the tenth place tells us to round the 9 to a 0 in the ones place, then the 5 to a 6 in the tens place.
[tex]260 \approx a[/tex]
The driver's increase in altitude is approximately 260 feet.
