A researcher wants to know if drinking beer makes a person more attractive to mosquitos. 120 people were recruited to partake in this experiment. Each person was randomly assigned to either drink beer or to ingest water. The subject after drinking their beverage was seated close enough so that odor from the individual would be detectable by the mosquitoes (note that the mosquitoes could not actually touch the humans). The researcher then recorded whether or not the mosquito flew toward the subject (assumed flying toward person meant they were attracted to them). 68 people were assigned to drinking beer, while the other 52 were assigned to drinking water. Out of the 68 who drank beer 43 of them had a mosquito fly toward them, while 26 of those who drank water had a mosquito fly toward them. (This is based loosely off an experiment performed by Lefevre et al. (PLOS ONE, 2010)).
Research Question: Are mosquitos more attracted to people who drink beer than water?

A tile is selected from seven tiles, each labeled with a different letter from the first seven letters of the alphabet.
The letter selected will be recorded as the outcome.
Consider the following events.
Event X: The letter selected comes before "D".
Event Y : The letter selected is found in the word "CAGE".
Give the outcomes for each of the following events.
If there is more than one element in the set, separate them with commas.
Answers
a) The only outcome that satisfies both events X and Y is the letter C.
b) The outcomes that satisfy either event X or event Y are {A, B, C, E, G}.
c) The complement of event X is {D, E, F, G}.
What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
The outcomes for each of the following events are:
(a) Event "X and Y": {C}
To satisfy both events X and Y, the letter selected must come before "D" (which includes the letters A, B, and C) and must be one of the letters in the word "CAGE" (which includes only the letter C). Therefore, the only outcome that satisfies both events X and Y is the letter C.
(b) Event "X or Y": {A, B, C, E, G}
The outcomes that satisfy event X are A, B, and C (since they come before "D"), and the outcomes that satisfy event Y are C, A, G, and E (since they are letters found in the word "CAGE"). Therefore, the outcomes that satisfy either event X or event Y are {A, B, C, E, G}.
(c) The complement of event X: {D, E, F, G}
The complement of event X is the set of outcomes that do not satisfy event X. The outcomes that do not satisfy event X are D, E, F, and G (since they come after or are equal to "D"). Therefore, the complement of event X is {D, E, F, G}.

D. For 30 players, the team manager would need 15 gallons of water ` true or false
Answers
Answer:
A.=False
B.=True
C.=False
D.=True
Step-by-step explanation:
The original ration is 2 gallons of water for 4 players.
Each player requires 1/2 gallon of water.
To get the amount of water needed multiply 1/2 by the amount of players.
1*(1/2) does not equal 1
2*(1/2) equals 1
10*(1/2) does not equal 4
30*(1/2) equals 15
If cos of Ф = 2/5, find sin Ф/2 and cos Ф/2. Assume the angles are in the 1st quartile
Answers
The exact values of the sine and the cosine of the half angle are √(3 / 10) and √(7 / 10), respectively.
What are the exact values of two trigonometric functions?
Herein we know the exact value of the cosine of an angle set in the first quadrant. Then, the half angle is also in the first quadrant, whose sine and cosine are, respectively:
cos 0.5Ф > 0, sin 0.5Ф > 0
sin 0.5Ф = √[(1 - cos 0.5Ф) / 2]
cos 0.5Ф = √[(1 + cos 0.5Ф) / 2]
First, replace the values of the cosine of the half angle:
sin 0.5Ф = √[(1 - 2 / 5) / 2]
cos 0.5Ф = √[(1 + 2 / 5) / 2]
Second, simplify the resulting expression:
sin 0.5Ф = √[(1 - 2 / 5) / 2]
sin 0.5Ф = √[(3 / 5) / 2]
sin 0.5Ф = √(3 / 10)
cos 0.5Ф = √[(1 + 2 / 5) / 2]
cos 0.5Ф = √[(7 / 5) / 2]
cos 0.5Ф = √(7 / 10)

What is the instantaneous rate of change y=sqrtx of at x = 2? Responses negative 1 over 2 negative 1 over 4 negative 1 none of these none of these
Answers
The instantaneous rate of change of y = √x at x = 2 is √2 / 2.
To find the instantaneous rate of change of y = √x at x = 2, we need to calculate the derivative of the function with respect to x and evaluate it at x = 2.
Taking the derivative of y = √x using the power rule for differentiation, we have:
dy/dx = (1/2) × x^(-1/2)
Now, substituting x = 2 into the derivative expression:
dy/dx = (1/2) × 2^(-1/2)
= (1/2) × √2
= √2 / 2
Therefore, the instantaneous rate of change of y = √x at x = 2 is √2 / 2.
None of the provided options (-1/2, -1/4, -1) are the correct instantaneous rate of change at x = 2.

The system of linear equations are 3y = 2-x and y = -2x-2
What is a system of linear equations?A system of linear equations is usually a set of two linear equations with two variables.
Given that, a graph,
The two coordinates for first line are (-3, 4) and (0, 3) and for line it is (-3, 4) and (0, -2)
We know, that standard equation of line passing through two points is:
(y-y₁) = (y₁-y₂)/(x₁-x₂)(x-x₁)
Finding the equation for the first line, (-3, 4) and (0, 3)
y-3 = (3-4)/(0+3)(x+3)
y-3 = -1/3(x+3)
y = -x/3+2
3y = 2-x.......(i)
Finding the equation for the second line, (-3, 4) and (0, -2)
y-4 = (-2)(x+3)
y = -2x-2.......(ii)
Hence, the two equations are 3y = 2-x and y = -2x-2

Firstly you should know what is a square: A square is a type of quadrilateral in which opposite sides are parallel and equal. All sides of the square are equal. The angles of the square are equal and each angle is 90°.
Since a square has 4 right angles, it can also be classified as a rectangle. Since a square has 4 sides of equal length, it can also be classified as a rhombus.
The opposite sides are parallel so a square can also be classified as a parallelogram.

In the polygon, using sum of exterior angles the value of x = 37°
What is a polygon?A polygon is a shape that has 3 or more sides.
Given the polygon which is a hexagon to find the value of x, we note that the angles are all exterior angles. We know that the sum of the exterior angles of a polygon is 360°.
So, we have the equation as
x + 2x + (x - 1) + 3x + (x + 18) + (x + 10) = 360°
Collecting like terms, we have that
x + 2x + x + 3x + x + x - 1 + 18 + 10 = 360°
9x + 27° = 360°
Subtracting 27° from both sides of the equation, we have that
9x + 27° - 27° = 360° - 27°
9x + 0 = 333°
9x = 333°
Dividing both sides by 9, we have that
x = 333°/9
x = 37°
So, the value of x = 37°

Answers
The t distribution is a family of similar probability distributions, with each individual distribution depending on a parameter known as the degrees of freedom.
How are the degrees of freedom determined?
When calculating degrees of freedom, one is subtracted from the total number of items in the data sample. Degrees of freedom are frequently addressed in relation to different types of statistical hypothesis testing, like a chi-square.The number of independent bits of information required to construct a statistic is called the degrees of freedom, which is frequently denoted by the letters v or df. It is determined by subtracting the number of constraints from the sample size.Finding essential cutoff values for inferential statistical tests requires consideration of the degree of freedom. Degrees of freedom often (but not always) relate to sample size depending on the sort of study you conduct.Hence, the t distribution is a family of similar probability distributions, with each individual distribution depending on a parameter known as the degrees of freedom.

As the triangles are similar to each other, using congruent theorem, we get the value of side g = 2m.
What are similar triangles?Comparable triangles are those that resemble one another but may not be precisely the same size. Comparable items are those that share the same shape but differ in size.
This shows that when shapes are amplified or demagnified, they superimpose one another. This feature of similar shapes is often known as "similarity".
As per the triangles,
g/5 = 4/10
⇒ g = 4 × 5/10
