Answer:
f = 11 2/7 (B)
Step-by-step explanation:
3 + f = 14 2/7
3+f-3 = 14 2/7 -3
f = 11 2/7
Thus, it's B.
Answer:
b) f = 11 2/7
Step-by-step explanation:
Now we have to,
→ Find the required value of f.
The equation is,
→ 3 + f = 14 2/7
Then the value of f will be,
→ 3 + f = 14 2/7
Converting mixed fraction to proper:
→ 3 + f = ((14 × 7) + 2)/7
→ 3 + f = (98 + 2)/7
→ 3 + f = 100/7
Subtract the Right hand side with 3:
→ f = (100/7) - 3
→ f = (100/7) - (21/7)
→ f = (100 - 21)/7
→ f = 79/7
Converting proper fraction to mixed:
→ f = (77 + 2)/7
→ f = (77/7) + (2/7)
→ [ f = 11 2/7 ]
Hence, the value of f is 11 2/7.

for a period of time, an island's population growth exponential. if the population doubles every 17 years and the current population is 1,725, what will the population be 10 years from now?
Using the exponential growth formulas, we get the population at 10 years would be 2593.
What is exponential growth?
A process called exponential growth sees a rise in quantity over time. It happens when the derivative of a quantity's instantaneous rate of change with respect to time is equal to the original quantity.
Given Initial population is Pt= 1725.
The doubling time of the population is D=17
Now we need to find the population at time t=10
Using the formula,
\(P_{t}=P_{0} (2)^{\frac{t}{D} } \\P_{t}=1725 (2)^{\frac{10}{17} } \\P_{t}=1725 (2)^{0.588}\\P_{t}=1725 \space\ . \space\ 1.503\\P_{t}=2593\)
Hence the population of the island in 10 years would be 2593.

line q passes through points (1,5) and (8, 2). line r is perpendicular to q. what is the slope of line r?
If line q passes through points (1,5) and (8, 2). line r is perpendicular to q, Then the slope of line r is 7/3.
The slope of a line is a measure of how steep the line is, or how much the line rises or falls as we move horizontally along it. It is defined as the ratio of the change in the vertical (y) coordinate to the change in the horizontal (x) coordinate between any two points on the line. In other words, it is the "rise" divided by the "run".
The formula for finding the slope between two points (x1, y1) and (x2, y2) on a line is:
slope = (y2 - y1) / (x2 - x1)
The slope can be positive, negative, zero or undefined. A positive slope means the line rises as we move from left to right, a negative slope means the line falls as we move from left to right, a slope of zero means the line is horizontal and a slope that is undefined means the line is vertical.
The slope of the line q passing through the points (1,5) and (8,2) can be found using the slope formula:
the slope of q = (change in y) / (change in x)
= (2 - 5) / (8 - 1)
= -3/7
Since line r is perpendicular to line q, the slope of line r will be the negative reciprocal of the slope of line q. That is:
the slope of r = -1 / slope of q
= -1 / (-3/7)
= 7/3
Therefore, the slope of line r is 7/3.

Which of the following are true statements?
If a * b = c, and a is not equal to zero, then b = c / a
If a * b = c, and b is not equal to zero, then a = c / b
If m / n = p, then m = p * n
All of these statements are true.
Answer:
(d) All of these statements are true.
Step-by-step explanation:
You want to know which statements relating multiplication and division are true.
Multiplicative inverseThe multiplicative inverse of (non-zero) 'a' is 1/a. The product of these is 1 (by definition).
Multiplicative identity1 is the multiplicative identity element, so 1·a = a.
Multiplication property of equalityStarting with a·b = c, we can multiply both sides of the equation by 1/a without altering its truthfulness.
(1/a)(a)(b) = (1/a)(c)
(a/a)(b) = c/a . . . . . . . for a ≠ 0
b = c/a
Using the other factor, we have ...
a = c/b . . . . . . . from (1/b)(a)(b) = (1/b)(c)
Substitution propertyWe can always substitute equals for each other. Then for c=m, a=n, b=p, the first of these equations is ...
p = m/n
m/n = p . . . . symmetric property of equality
Effectively, all of the multiplication and division relations shown are true:
ab = c ⇔ b = c/a . . . . . . . a ≠ 0ab = c ⇔ a = c/b . . . . . . . b ≠ 0m/n = p ⇔ m = pn . . . . . n ≠ 0__
Additional comment
In the first two cases, we included the caveat that the divisor could not be zero. This is also true of the last case (m/n=p). However, in this case, we assume that p is defined, which automatically means that n ≠ 0.
<95141404393>
All of the statements provided are true. If two numbers, a and b, have a product of c, then dividing c by a will yield the value of b, as long as a is not equal to zero. All options are true.
In the first statement, if a * b = c and a is not equal to zero, then dividing both sides of the equation by a gives us (a * b) / a = c / a. The term (a * b) / a simplifies to b, so we have b = c / a, which confirms the truth of the statement.
Similarly, in the second statement, if a * b = c and b is not equal to zero, dividing both sides of the equation by b results in (a * b) / b = c / b. The term (a * b) / b simplifies to a, so we have a = c / b, validating the statement.
Finally, in the third statement, if m / n = p, multiplying both sides of the equation by n gives us (m / n) * n = p * n. The term (m / n) * n simplifies to m, so we have m = p * n, confirming the truth of the statement.
In summary, all of the given statements hold true, as they follow logical mathematical operations and principles.

1. The day of the week 100 days from today can be determined by calculating the remainder when dividing 100 by 7 and adding it to the current day of the week.
The day of the week 100 days from today, assuming today is Tuesday, will be Sunday.
There are 7 days in a week, so after every 7 days, the day of the week repeats. Therefore, to find the day of the week 100 days from today, we need to calculate the remainder when dividing 100 by 7.
100 ÷ 7 = 14 remainder 2
Adding this remainder to the current day (Tuesday) gives us:
Tuesday + 2 = Thursday
So, 100 days from today will be Thursday. However, if we want to find the day of the week, we need to consider that Tuesday is the second day of the week (with Sunday being the first day). Adding the remainder 2 to Tuesday:
Tuesday + 2 = Thursday
Therefore, the day of the week 100 days from today will be Sunday.

The data includes a concave mirror with a radius of curvature of +31.5 cm and magnification of m = 3.40. The formula for magnification is m = v/u, and the focal length is f = r/2. Substituting the values, we get u = v/m, and using the mirror formula, the distance of the object from the mirror is 10.15 cm.
Given data: Radius of curvature of a concave mirror, r = +31.5 cm Magnification produced by the mirror, m = 3.40
We know that the formula for magnification is given by:
m = v/u where, v = the distance of the image from the mirror u = the distance of the object from the mirror We also know that the formula for the focal length of the mirror is given by :
f = r/2where,f = focal length of the mirror
Using the mirror formula:1/f = 1/v - 1/u
We know that a concave mirror has a positive focal length, so we can replace f with r/2.
We can now simplify the equation to get:1/(r/2) = 1/v - 1/u2/r = 1/v - 1/u
Also, from the given data, we have :m = v/u
Substituting the value of v/u in terms of m, we get: u/v = 1/m
So, u = v/m Substituting the value of u in terms of v/m in the previous equation, we get:2/r = 1/v - m/v Substituting the given values of r and m in the above equation, we get:2/31.5 = 1/v - 3.4/v Solving for v, we get: v = 22.6 cm Now that we know the distance of the image from the mirror, we can use the mirror formula to find the distance of the object from the mirror.1/f = 1/v - 1/u
Substituting the given values of r and v, we get:1/(31.5/2) = 1/22.6 - 1/u Solving for u, we get :u = 10.15 cm
Therefore, the distance of the mirror from the face is 10.15 cm. The units are centimeters (cm).Answer: 10.15 cm.

Step-by-step explanation:
Formula of Perimeter: w + w + l + l or 2w + 2l
l = 5w
2l + 2w = 120
2(5w) + 2w = 120
10w + 2w = 120
12w = 120
w = 10
l = 5(10)
l = 50
Check:
2l + 2w = 120
2(50) + 2(10) = 120
100 + 20 = 120
120 = 120
Hope This Helps!
Lets denote our variables as:
x the width of the rectangle5x the length of the rectangleThe formula for the perimeter of a rectangle is P = 2L + 2W, where L is the length of the rectangle and W is the width of the rectangle. We know that the perimeter of the rectangle is 120m, so we can write:
2(x) + 2(5x) = 120
2x + 10x = 120
12x = 120
x = 120/12
x = 10 m → Width of the rectangle
Substituting in the length:
5x = 5(10) = 50 m → Length of the rectangle
The length of the rectangle is 50 m and its width is 10 m.

(-t/2 - 7/8)
The particular solution is: Xp(t) = (t/4 - 19/16; -t/2 + 7/8). The correct option is b.
The given system of linear differential equations can be written as:
X'(t) = AX + B(t),
where X'(t) is the derivative of X(t), A is the matrix (2 3; 2 1), and B(t) is the column vector (t; 1). To find the particular solution, we can apply the method of undetermined coefficients. We assume a particular solution of the form Xp(t) = (at + b; ct + d), where a, b, c, and d are constants to be determined.
Taking the derivative of Xp(t), we get Xp'(t) = (a; c). Now, we substitute Xp(t) and Xp'(t) into the given equation:
(a; c) = (2 3; 2 1) (at + b; ct + d) + (t; 1).
Multiplying the matrix and vector, we get:
(a; c) = (2(at + b) + 3(ct + d); 2(at + b) + 1(ct + d)) + (t; 1).
Equating the components, we get the following system of linear equations:
a = 2a + 2b + 3c + 3d + 1,
c = 2a + 2b + c + d + 0.
Solving this system, we find a = t/4 - 19/16, b = -t/2 + 7/8. Therefore, the particular solution Xp(t) is:
Xp(t) = (t/4 - 19/16; -t/2 + 7/8),

The GCD of 2⁸ * 3⁹ * 5⁹ and 2⁴ * 3⁴ * 5⁴ is 810,000.
To find the GCD of 2⁸ * 3⁹ * 5⁹ and 2⁴ * 3⁴ * 5⁴, we will examine the prime factors of both numbers individually and compare their powers.
Prime factorization of the first number, 2⁸ * 3⁹ * 5⁹:
2⁸ = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 256
3⁹ = 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 = 19683
5⁹ = 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 * 5 = 1953125
Prime factorization of the second number, 2⁴ * 3⁴ * 5⁴:
2⁴ = 2 * 2 * 2 * 2 = 16
3⁴ = 3 * 3 * 3 * 3 = 81
5⁴ = 5 * 5 * 5 * 5 = 625
Now, let's compare the powers of the common prime factors in both numbers:
The common prime factor 2 appears with a higher power in the first number (2⁸) than in the second number (2⁴). Therefore, the highest power of 2 that divides both numbers is 2⁴ = 16.
The common prime factor 3 appears with a higher power in the first number (3⁹) than in the second number (3⁴). Therefore, the highest power of 3 that divides both numbers is 3⁴ = 81.
The common prime factor 5 appears with a higher power in the first number (5⁹) than in the second number (5⁴). Therefore, the highest power of 5 that divides both numbers is 5⁴ = 625.
To find the GCD, we multiply the common prime factors with the lowest powers:
GCD = 2⁴ * 3⁴ * 5⁴ = 16 * 81 * 625 = 810,000.

When testing the difference between two dependent population means, the test statistic is based on a ________.
When testing the difference between two dependent population means, the test statistic is based on a standard deviations of the differences.
The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Answer:
28
Step-by-step explanation:
\(80 \times \frac{35}{100 } \\ = 28\)
Answer:
28
Step-by-step explanation:
From the given pie chart:
35% of the people surveyed selected blue as their favorite color.If a total of 80 people were surveyed, to find the number of people in the sample that chose blue, simply find 35% of 80:
\(\begin{aligned}\implies \sf 35\%\;of\;80 & = \sf \dfrac{35}{100} \times 80\\\\&= \sf \dfrac{35 \times 80}{100} \\\\&= \sf \dfrac{2800}{100} \\\\&=\sf 28\end{aligned}\)
Therefore, 28 people from a total of 80 surveyed chose blue as their favorite color.
With Alpha set to .05, would we reduce the probability of a Type
I Error by increasing our sample size? Why or why not? How does
increasing sample size affect the probability of Type II Error?
With Alpha set to .05, increasing the sample size would not directly reduce the probability of a Type I error. The probability of a Type I error is determined by the significance level (Alpha) and remains constant regardless of the sample size.
However, increasing the sample size can indirectly affect the probability of a Type I error by increasing the statistical power of the test. With a larger sample size, it becomes easier to detect a statistically significant difference between groups, reducing the likelihood of falsely rejecting the null hypothesis (Type I error).
Increasing the sample size generally decreases the probability of a Type II error, which is failing to reject a false null hypothesis. With a larger sample size, the test becomes more sensitive and has a higher likelihood of detecting a true effect if one exists, reducing the likelihood of a Type II error. However, it's important to note that other factors such as the effect size, variability, and statistical power also play a role in determining the probability of a Type II error.
