Answer:
at least 5
Step-by-step explanation:
If the question was similar to the one given below
A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter or a pair of distinct letters written in alphabetical order. What is the least number of letters that can be used if there are 12 participants, and each participant is to receive a different code?
The answer would be as follows
If we use 3 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
4C2= 6 ways to use these letters and the comma
If we use 4 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
5C2= 10 ways to use these letters and the comma
If we use 5 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
6C2= 15 ways to use these letters and the comma
We need the least number of the alphabets to assign codes to 12 participants.
So the least number of alphabets is 5 because it can give codes to at least to 12 people .
Pair of alphabets + distinct letter ≥ 12
5 + 1 ≥ 12
6c2 ≥ 12
15 ≥ 12

Step-by-step explanation:
Hope this helps !!!
Answer:
10.
Step-by-step explanation:
Picking out 2 convenient points, (3, 30) and (0, 0):
Slope = (30-0)/(3-0)
= 30/3
= 10.
Round 5.955 to the nearest tenth.
Answer:
6.
Step-by-step explanation:
To round 5.955 to the nearest tenth consider the hundredths’ value of 5.955, which is 5 and equal or more than 5. Therefore, the tenths value of 5.955 increases by 1 to 0.

Find the exact value of the following limit: lim x approaches 0 e^6x... check photo above.
Substituting x = 0 directly gives the indeterminate form 0/0, so you can use l'Hopital's rule (and you'll have to do that twice):
[tex]\displaystyle\lim_{x\to0}\frac{e^{6x}-6x-1}{x^2}=\lim_{x\to0}\frac{6e^{6x}-6}{2x}=\lim_{x\to0}\frac{36e^{6x}}2[/tex]
The limand is continuous everywhere, so you can plug in x = 0 to get 36•1/2 = 18.

a. x=-3
b. x=-2
c. x=-1
d. x=0
e. x=1
f. x=2
g. x=3
Answer:
[tex] \frac{7x + 6}{2} \leqslant {3x + 2}\\[/tex]
a. x=-3✓
b. x=-2✓
c. x=-1
d. x=0
e. x=1
f. x=2
g. x=3
Step-by-step explanation:
[tex] \frac{7x + 6}{2} \leqslant 3x + 2 \\ 7x + 6 \leqslant 2(3x + 2) \\ 7x + 6 \leqslant 6x + 4 \\7x - 6x \leqslant 4 - 6 \\ \boxed {x \leqslant - 2}[/tex]

For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used
Question:
For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.
Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Answer:
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
Step-by-step explanation:
Given
[tex]Water = 1L[/tex]
[tex]Sucrose = 150mL[/tex]
[tex]Saline= 600mL[/tex]
Required
Express as a ratio to the simplest form
First convert the volume of water to mL
[tex]Water = 1L[/tex]
[tex]Water = 1 * 1000mL[/tex]
[tex]Water = 1000mL[/tex]
Express as ratio:
[tex]Water : Sucrose : Saline = 1000mL : 150mL : 600mL[/tex]
[tex]Water : Sucrose : Saline = 1000 : 150 : 600[/tex]
Divide through by 10
[tex]Water : Sucrose : Saline = 100 : 15 : 60[/tex]
Divide through by 5
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
The ratio can not be further simplified
Terry pays £480 per month in rent.
His landlord decides to increase the rent by 7.5%.
How much rent does he pay now?
Answer: £516
Step-by-step explanation:
7.5 increase = 100 + 7.5 = 107.5
107.5/100 = 1.075 (multiplier)
480 x 1.075 = 516

Answer:
Three fifths
Step-by-step explanation:
Since 10 was divided by 2 to get 5,
you just do the same to the top half of the fraction.
So when you divide 6 by 2, you get 3.
So it is equal to 3/5, or three fifths.
And 3/5 is equivalent to 6/10
You have budgeted $4,800 for a company to complete guest satisfaction surveys for you. They charge $1,800 + $6 per respondent. How many respondents will you be able receive for the money paid?
Answer:
6
Step-by-step explanation:
There are 500 respondents will you be able receive for the money paid.
What is mean by expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The budgeted for a company to complete guest satisfaction surveys for you is, $4,800.
And, They charge $1,800 + $6 per respondent.
Now,
Let Number of respondents will you be able receive for the money paid is, x
Hence, We can formulate;
⇒ $1800 + $6x = $4800
⇒ 1800 + 6x = 4800
⇒ 6x = 4800 - 1800
⇒ 6x = 3000
⇒ x = 500
Thus, There are 500 respondents will you be able receive for the money paid.

introduces a study where researchers studying the relationship between honesty, age, and self-control conducted an experiment on 1G0 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group. (a) Identify the population of interest and the sample in this study. (b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
The solution to this question can be defined as follows:
Step-by-step explanation:
In choice a:
Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.
In choice b:
These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg
Determine whether each table of values represents a linear function. For those that do not explain why not.
Answer:
Table M does not represent a linear function, however table N does.
Step-by-step explanation:
In table M, y does not have a constant rate of change in relation to x
(in table M, the x value of -3 is repeated and the y value is not constant with the x value of -3)
In table N, the y value has a constant rate of change of 6 corresponding to each x value.
