Answer:

Step-by-step explanation:

we have to multiply

Answer:

16/20

Step-by-step explanation:

Among the given candidates, the operations in (b) and (c) are binary operations on the respective sets. However, the operations in (a) and (d) fail to be binary operations due to closure violation or reliance on external criteria.

(a) The operation x# = \(x^{2}\) is not a binary operation on set S = {1, 2, 3}. To be a binary operation, it must take two elements from the set and produce another element in the set. However, when x = 2, the result \(x^{2}\) = 4 is not an element in set S, violating the requirement for closure. Therefore, this operation fails to be a binary operation on S.

(b) The operation x + 1 if x is odd, x if x is even is a binary operation on set S = {1, 2, 3}. It takes two elements from the set and produces another element in the set, satisfying the closure property. For example, 2 + 1 = 3, which is an element in S. Hence, this operation is a binary operation on S.

(c) The operation x + y = that fraction, x or y, with the smaller denominator is a binary operation on the set of all fractions. It takes two fractions and produces another fraction, satisfying closure. The result is determined by selecting the fraction with the smaller denominator. Therefore, this operation is a binary operation on the set of all fractions.

(d) The operation x + y = that person, x or y, whose name appears first in an alphabetical sort is not a binary operation on the set of 10 people with different names. This operation does not combine two elements from the set to produce another element in the set, violating closure. It relies on external sorting criteria (alphabetical order) and does not operate solely on the elements of the set itself. Thus, this operation fails to be a binary operation on the given set.

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form, with the value of center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

\((x-h)^2+(y-k)^2=r^2\)

Here (h,k) is the center of the circle and (r) is the radius of the circle.

For the first problem,

\(x^2+(y+2)^2=64\)

Rewrite the equation to make it the equation of circle as,

Answer: for this problem. What we're going to do essentially, this is an exercise of using the formula for finding the derivative of the inverse of a function. So we have the derivative of the inverse of F would be equal to one over the derivative of F. So F prime evaluated at f inverse of X. So in this case we have X equals three. So F inverse of three, prime will be equal to one over F prime evaluated at f inverse of three. Now, looking at the table of values that you have, well, F inverse of three is going to be the X value such that X equals, or the the X values such that F equals three. So we can see that F equals three when X equals negative one. So we have one over F prime evaluated at negative one and F prime of negative one, we can see it is equal to one. So we'd have won over one or just one is the final answer.

Step-by-step explanation:

Answer:

5/8 i TOOK THE EXAM REVIEW

Step-by-step explanation:

To find the equation of the tangent line at a given point, we follow the steps given below: We find the partial derivatives of the given function w.r.t x and y separately and then substitute the given point (1, 1) to get the derivative of the curve at that point.

In order to calculate ((g)/(f))(1), we need to first calculate g/f. Hence, let's calculate both g(x) and f(x)g(x) = (-5 + x)(-4 + x)

= 20 - 9x + x^2

and f(x) = -7 + 8x
Now, let's divide g(x) by f(x)g/f = g(x)/f(x)

= ((20 - 9x + x^2))/(8x - 7)

Now, let's substitute x = 1g/f (1)

= ((20 - 9(1) + (1)^2))/(8(1) - 7)

= (12/1)

= 12

Therefore,  the denominator cannot be 0. Therefore, let's set the denominator to 0 and solve for x 8x - 7 = 0

⇒ 8x = 7

⇒ x = 7/8

Therefore, the denominator becomes 0 at x = 7/8.

Hence, x = 7/8 is not in the domain of (g)/(f).

Therefore, ((g)/(f))(1) = 12.

And, x = 7/8 is not in the domain of (g)/(f). In order to calculate ((g)/(f))(1), we need to first calculate g/f. Hence, let's calculate both g(x) and f(x)g(x) = (-5 + x)(-4 + x)

= 20 - 9x + x^2 and

f(x) = -7 + 8x

Now, let's divide g(x) by f(x)g/f = g(x)/f(x)

= ((20 - 9x + x^2))/(8x - 7)

For (g)/(f) to be defined, the denominator cannot be 0. Therefore, let's set the denominator to 0 and solve for x 8x -7 = 0 ⇒ 8x = 7

⇒ x = 7/8

Therefore, the denominator becomes 0 at x = 7/8.

Hence, x = 7/8 is not in the domain of (g)/(f).

Probability of 1st/2nd/10th sample = 1/10

Step-by-step explanation:

All the possible combinations of the 3 size samples from a 5 size population have been listed without repetition.

Total Numbers of Samples = 10

To find the probability of finding the first sample from random sampling procedure,

Probability = Number of desired outcomes/ Total number of outcomes

Where Number of desired outcome is 1 and total number of outcomes is 10.

Probability = 1/10

Similarly, to find 2nd sample or 10th sample, the number of desired outcomes is same i.e 1, hecne the probability remains the same i.e 1/10

Possible samples:

(G,L), (G,S), (G,A), (G,P), (L,S), (S,A), (A,P), (L,P), (S,P), (A,L).

a) Given:

Population size \(N=5\).

Sample size \(n=2\)

Possible sample (without replacement)

\(\Rightarrow 5C_{2}=\frac{5!}{2!\times 3!}\)

\(=\frac{5\times 4}{2}\)

\(=10\)

\(10 samples:-\)

Possible samples:

(G,L), (G,S), (G,A), (G,P), (L,S), (S,A), (A,P), (L,P), (S,P), (A,L).

b) Event: \(E\to\)choosing sample second and tenth.

\(E=\left\{\left ( G,S \right ),\left ( A,L \right ) \right\}\\n\left ( E \right )=2\\n(S) =10\)

The Probability of that it is the first sample.

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

In the given figure

∵ ABC is a triangle

∵ D is a point on side AB

∵ E is a point on side BC

∵ DE // AC

∵ AC is the third side of the triangle

→ That means DE divides the sides AB, BC into parts that have the same ratio

∴ \(\frac{BD}{DA}\) = \(\frac{BE}{EC}\)

∵ BD = 6 and DA = 4

∵ BE = x + 1 and EC = x

→ Substitute them in the ratio above

∴ \(\frac{6}{4}\) = \(\frac{x+1}{x}\)

→ By using the cross multiplication

∵ 6 × x = 4 × (x + 1)

∴ 6x = 4(x + 1)

∴ 6x = 4(x) + 4(1)

∴ 6x = 4x + 4

→ Subtract 4x from both sides

∵ 6x - 4x = 4x - 4x + 4

∴ 2x = 4

→ Divide both sides by 2 to find x

∴ x = 2

The 95% confidence interval for the difference between the two population proportions is (0.1, 0.16).

The parameter being estimated is the difference between two population proportions.

To find the 95% confidence interval for this parameter, we can use the margin of error formula:

where z is the z-score for the desired level of confidence (95% in this case), p1 and p2 are the sample proportions, and n1 and n2 are the sample sizes.

We know that the difference between the sample proportions (phat1 - phat2) is 0.13, and the margin of error is 3%. Since the sampling distribution is assumed to be symmetric and bell-shaped, we can assume that the standard deviation of the difference between the sample proportions is equal to the standard error, which can be estimated by the margin of error.

Setting up an equation using the margin of error formula, we get:

We don't know the sample sizes or the sample proportions, so we can't solve for the confidence interval directly. However, we can use a conservative estimate for the standard deviation of the difference between the sample proportions:

Using this formula, we get:

This is approximately equal to the margin of error, so we can assume that z ≈ 1.96 (the z-score for 95% confidence) and use the formula:

Therefore, the 95% confidence interval for the difference between the two population proportions is (0.1, 0.16).

What is equation ?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Let c be denoted as cashew and p be denoted as peanuts

c + p = 10  ⇒ (1)

5.6c + 2.3p = 3.29*10 ⇒ (2)

Multiply eq(1) by 560

Multiply eq(2) by 100

560c + 560p = 5600

560c + 230p = 3290

Subtract and solve for "p":

330p = 2310

p = 7  (amt. of peanuts needed)

substitute  the value of p in eq(1)

c + 7 = 10

c = 3  (amt. of cashews needed)
