Two researchers make a test concerning standardized exam performance among senior high school students in one of two local communities. Researcher A tests performance from the population in the northern community, where the standard deviation of test scores is 110 ( ); Researcher B tests performance from the population in the southern community, where the standard deviation of test scores is 60 ( ). All other things being equal, which researcher has more power to detect an effect? Explain.
Answer:
Researcher B
Step-by-step explanation:
Normally, when all other things being equal, we usually say that power is higher when the standard deviation is small than when it is large.
Now, from researcher A, standard deviation is 110 while from researcher B, standard deviation is 60.
We can see that the standard deviation for researcher B is smaller than that of researcher A.
Therefore, we can conclude that since the standard deviation for researcher B is lesser than that of researcher A, it means that Researcher B will have more power to detect an effect.
Which of the following are solutions to the equation below? Check all that apply. x2 + 10x + 25 = 2
Answer:
-5+√2 and -5-√2
Step-by-step explanation:
With the quadratic formula:
\(\displaystyle x^2 + 10x + 25 = 2\\\\x^2+10x+23=0\\\\x=\frac{-10\pm\sqrt{10^2-4(1)(23)}}{2(1)}=\frac{-10\pm\sqrt{100-92}}{2}=\frac{-10\pm\sqrt{8}}{2}=\frac{-10\pm2\sqrt{2}}{2}=-5\pm\sqrt{2}\)
We can also complete the square (which is faster):
\(x^2+10x+25=2\\(x+5)^2=2\\x+5=\pm\sqrt{2}\\x=-5\pm\sqrt{2}\)
You roll a die 2 times. What is the probability or rolling a 6 and then a 2?
Answer:
1 out of 6
Step-by-step explanation:
Each roll of the die is an independent event. This means that the second roll does not rely on the first roll. The probability of rolling a six is one out of six. The probability of rolling a two is also one out of six. Since the two events are independent of each other, you would take the average of the two probabilities, which since they are both one out of six, the probability of rolling a six and then a two is one out of six.

The given equation is e' = 120, where e represents some variable.
To solve for e, we can start by dividing both sides of the equation by the coefficient of e, which is 1:
e' / 1 = 120 / 1
Simplifying the right-hand side, we get:
e' = 120
This means that the value of e is equal to 120. So the solution to the equation e' = 120 is e = 120.
To find the approximate value of e, we can use a calculator to evaluate the expression. Since e is a variable, we cannot substitute it directly into the calculator. However, we can estimate the value of e by rounding it to a reasonable number of decimal places.
In this case, since e' is given as 120, we can assume that e is also in the same units. So we can round e to the nearest whole number:
e ≈ 120

tickets to a movie cost $10.50 for adults and $7.25 for students. you and a few friends purchased 8 tickets for $61.25. how many adult tickets and student tickets were purchased?
Answer:
1 adult ticket and 7 student tickets were purchased
Step-by-step explanation:
let a represent number of adult tickets purchased and s the number of student tickets purchased, then
a + s = 8 ( subtract s from both sides )
a = 8 - s → (1) ← based on total tickets purchased
10.5a + 7.25s = 61.25 → (2) ← based on cost of tickets
substitute a = 8 - s into (2)
10.5(8 - s) + 7.25s = 61.25
84 - 10.5s + 7.25s = 61.25
84 - 3.25s = 61.25 ( subtract 84 from both sides )
- 3.25s = - 22.75 ( divide both sides by - 3.25 )
s = 7
substitute s = 7 into (1)
a = 8 - 7 = 1
that is 1 adult ticket and 7 student tickets were purchased

BC is tangent to circle A, and the value of r is 10.
Given,
BC=24
CD=16
AD=AB=r
To find the value of r, we can use the fact that a tangent line to a circle is perpendicular to the radius at the point of tangency. So we know that angle ABD is a right angle, and we can use the Pythagorean theorem
The Pythagorean theorem can be used to calculate the value of r:
\(AB^2+BC^2=AC^2\)
\(r^2+24^2=(r+16)^2\)
\(r^2= (r+16)^2-24^2\)
\(r^2\)= \(r^2\)+256+32r-576
\(r^2\)=\(r^2\)+32r-320
\(r^2-r^2\)-32r=-320
-32r=-320
r=320/32
r=10

Five friends take a maths test
Adam, Brandon, Chen together together scored 200 marks
Brandon, Chen and Damion together scored 215
Chen, Damion, Erica together scored 224
Damion and Erica scored more than Chen
The five of them together scored 350 marks
What are their individual scores
Answer:
\(Adam = 60\)
\(Brandon = 66\)
\(Chen = 74\)
\(Damion = 75\)
\(Erica = 75\)
Step-by-step explanation:
Given
Represent each friend with the first letter of their name
So:
\(A + B + C =200\)
\(B + C + D = 215\)
\(C + D +E= 224\)
\(A + B + C + D + E = 350\)
\(D , E > C\)
Substitute: \(A + B + C =200\) in \(A + B + C + D + E = 350\)
\(200 + D + E = 350\)
Collect like terms
\(D + E = 350-200\)
\(D + E = 150\)
Make D + E the subject in \(C + D +E= 224\)
\(D + E = 224 - C\)
Substitute \(D + E = 224 - C\) in \(D + E = 150\)
\(224 - C = 150\)
Collect like terms
\(C = 224 - 150\)
\(C = 74\)
Substitute \(C = 74\) in \(A + B + C =200\) and \(B + C + D = 215\)
\(A + B + 74 = 200\)
\(A + B =- 74 + 200\)
\(A + B =126\)
\(B + 74 + D = 215\)
\(B + D = -74 + 215\)
\(B + D = 141\)
So, we have:
\(A + B =126\)
\(B + D = 141\)
\(D + E = 150\)
We have: \(D , E > C\)
i.e.
\(D , E > 74\) and \(D + E = 150\)
For \(D , E > 74\) and \(D + E = 150\) to be true,
\(D = E = 75\)
i.e.
\(75 + 75 = 150\)
So, we have:
\(D = 75\)
\(E = 75\)
\(B + D = 141\)
\(B + 75 = 141\)
\(B = 141 - 75\)
\(B = 66\)
\(A + B =126\)
\(A + 66 = 126\)
\(A = 126 - 66\)
\(A = 60\)

What is the domain of the function?
Answer:
we conclude that the domain of 'g' should be:
0 ≤ g ≤ 14Step-by-step explanation:
We know that the domain of a function is the set of input or argument values for which the function is real and defined.Given that the function m(g) provides the number of miles a car can travel on 'g' gallons of gas.
Also, the fuel tank holds 14 gallons which allows a maximum ride of 504 miles.
As the distance covered by Car in miles is dependent on the availability of the fuel.
Thus, fuel gallons 'g' is an independent quantity and hold x-values.
Given that the fuel tank holds 14 gallons 'g'.Thus, the domain of 'g' should be:

(b) If you put $8350 in the ATM each day, what percent of the days in a month should you expect to run out of cash?
You can expect to run out of cash on approximately 39.45% of the days in a month when withdrawing $8,350 every day.
To determine the percentage of days in a month where you can expect to run out of cash, we'll need to consider the following terms: daily withdrawal, monthly cash usage, and average days in a month.
1. Daily withdrawal: This is the amount of money you withdraw from the ATM each day. In this case, you withdraw $8,350 every day.
2. Monthly cash usage: This is the total amount of money you will withdraw in a month. To calculate this, multiply the daily withdrawal by the number of days in a month. Since the average number of days in a month is approximately 30.42 (365 days in a year / 12 months), the monthly cash usage would be $8,350 x 30.42 ≈ $253,507.
3. Average days in a month: As mentioned earlier, this is approximately 30.42 days.
Now, we need to determine the number of days you would run out of cash. To do this, divide your monthly budget by the daily withdrawal amount. Let's assume you have a budget of $100,000:
Days without cash = $100,000 / $8,350 ≈ 11.98 days.
Since you can't have a fraction of a day, round it up to 12 days.
4. Calculate the percentage: To find the percentage of days you would run out of cash, divide the number of days without cash by the average number of days in a month and multiply by 100:
Percentage = (12 days / 30.42 days) x 100 ≈ 39.45%.
So, you can expect to run out of cash on approximately 39.45% of the days in a month when withdrawing $8,350 every day.

What is the length of the fence around the enclosure not including the gates?
The length of the fence around the enclosure not including the gates is:2l + 2w + 8 m
To find the length of the fence around the enclosure, we need to first find the perimeter of the rectangle and then subtract the combined length of the two gates from it.
Let's assume the length of the rectangle is 'l' and the width is 'w'.
From the given data, we know that each gate is 4 m wide.
Therefore, the width of the rectangle is:
Width = w + (4 m + 4 m) = w + 8 m
The perimeter of the rectangle is:
P = 2l + 2(w + 8 m) = 2l + 2w + 16 m
Now, we need to subtract the combined length of the two gates from the perimeter:
P - 2 × 4 m = 2l + 2w + 16 m - 8 m = 2l + 2w + 8 m
So, the length of the fence around the enclosure not including the gates is:2l + 2w + 8 m

The length of the hypotenuse is 12.52 yards.
Given that a right triangle, we need to find the value of the hypotenuse x,
Trigonometric ratios can be calculated by taking the ratio of any two sides of the right-angled triangle.
We can evaluate the third side using the Pythagoras theorem, given the measure of the other two sides. We can use the abbreviated form of trigonometric ratios to compare the length of any two sides with the angle in the base.
Let us consider a right-angled triangle with one of its acute angles to be x. Then the cosine formula is, cos x = (adjacent side) / (hypotenuse), where "adjacent side" is the side adjacent to the angle x, and "hypotenuse" is the longest side (the side opposite to the right angle) of the triangle.
We know that, the cosine of the angle is the ratio of the base to the hypotenuse,
So,
Cos 37° = 10 / x
x = 10 / Cos 37°
x = 12.52
Hence the length of the hypotenuse is 12.52 yards.
