The answer is x =1

Answer:

x = 4

Step-by-step explanation:

The steps we need to take:

1. Simplify left side.

2. Separate the variable and its coefficient from constants

3. Divide both sides by the coefficient to find "x

1) Simplify left side.

5(3x - 4) + 12 = 52

15x - 20 + 12 = 52

15x - 8 = 52

2) Separate the variable and its coefficient from constants by adding 8 to both sides.

15x - 8 + 8 = 52 + 8

15x = 60

3) Divide both sides by the coefficient to find x. (the coefficient is the number that comes before the variable)

15x / 15 = 60 / 15

x = 4

Answer:

B

Step-by-step explanation:

-13-7=-20

Check:

13+7=20

The correct answer is B.

The option that explains how ΔAEI could be proven similar to ΔDEH using the AA similarity postulate is B. ∠AEI ≅ ∠DEH because vertical angles are congruent; rotate ΔHED 180° around point E, then translate point D to point A to confirm ∠IAE ≅ ∠HDE.

The AA postulate in Euclidean geometry asserts that two triangles are similar if their corresponding angles are congruent. The AA postulate is derived from the fact that the total of a triangle's internal angles is always equal to 180°.

In this case, triangle AEI as well as DEH will be equal. Also, it's important to note that vertically opposite angles are equal.

In conclusion, the correct option is B.

For all four triangles, we have the angles 50°, 60° and 70°, and one side with length equal 9.

In the options b, c and d, the side measuring 9 is between the angles 50° and 60°, but for option a, this side is between the angles 50° and 70°, so it's a different side, therefore the triangle is not congruent.

So the correct option is 'a'.

The correct statement is: "The domains of g(x) and f(x) are the same, but their ranges are not the same."

The statement "The domains of g(x) and f(x) are not the same, and their ranges are also not the same" is correct. In general, when considering functions g(x) and f(x) derived from a parent function, the transformations applied to the parent function can affect both the domain and the range. The domain of a function refers to the set of all possible input values, while the range represents the set of all possible output values. Through transformations such as shifts, stretches, compressions, or reflections, the domain and range of a function can be altered. Therefore, it is possible for the domains and ranges of g(x) and f(x) to differ from each other and from the parent function.

Answer: Factoring is essentially the reverse of the distributive property. You are basically trying to simplify the polynomial by taking out common factors. You also may try reducing the power (or the highest exponent) of the polynomial with factoring. I would say that factoring is the breaking down of a bigger polynomial into a product of two expressions that are usually multiplied by each other. One specific use of factoring we see a lot is the quadratic formula.

1. Quadratic Factoring --> \(x^2+2x-15\) --> we have an \(x^2\) but we want there to only be "\(x\)"s. Here we need to constant numbers (integers), that multiply together to get \(-15\), and add up to \(+2\). (5 and -3)

    - \(x^2+2x-15\) ==> \(x^2+5x-3x-15\) ==> \(x(x+5)-3(x+5)\) ==> \((x-3)(x+5)\)

Above: We can see that we factor out \(x\) from \(x^2+5x\) (This shows that we are aiming to break it down to make it easier to evaluate).

Remember: Factoring does not always mean that the polynomial is in a simpler form. There are many situations where factoring is totally unnecessary and complicates the polynomial even more.

--------------------------------------------------------------------------------------------------------------On a separate note: Distributive Property, if you are unsure or not fully sure on what that means, is when you multiply two expressions together to create one expression. Multiple expressions are combining into one.

For a given sample proportion of 0.5, the sample size that will produce the widest confidence interval is the largest option given, which in this case is 80.

The sample size that will produce the widest 95% confidence interval, given a sample proportion of 0.5, is option b, 80. This is because the width of the confidence interval is directly proportional to the sample size, meaning that as the sample size increases, the confidence interval becomes narrower.

Additionally, the width of the confidence interval is inversely proportional to the square root of the sample size. Therefore, for a given sample proportion of 0.5, the sample size that will produce the widest confidence interval is the largest option given, which in this case is 80.

the expected number of wins for the month of November is approximately 4.55.

To find the expected number of wins for the month of November, we first need to calculate the mean or expected value of the binomial distribution. We know that the probability of winning any given game is 0.3789, and there are 12 games in November.

Let X be the number of games won in November, then X follows a binomial distribution with parameters n = 12 and p = 0.3789.

The expected value of a binomial distribution is given by E(X) = np, where n is the number of trials and p is the probability of success in each trial. So, in this case, the expected number of wins for the month of November is:

E(X) = np = 12 x 0.3789 = 4.547

This means that, on average, we can expect the hockey team to win about 4 or 5 games in November, based on their historical win rate. However, it's important to note that this is just an average and there is always variability in the number of wins in any given month or season.

The difference in length between a 1 1/4-inch bottom and a 3/8-inch bottom is 7/8 inches. To find the difference in length between a 1 1/4-inch bottom and a 3/8-inch bottom, we need to subtract the lengths of the two bottoms.

1 1/4 inches can be written as 1 + 1/4 inches, which is equal to 4/4 + 1/4 inches, resulting in 5/4 inches.

3/8 inch remains as 3/8 inch.

Now we can subtract the lengths:

5/4 inches - 3/8 inch

To subtract fractions, we need a common denominator. The least common denominator (LCD) of 4 and 8 is 8.

Converting both fractions to have a denominator of 8:

5/4 inches = (5/4) * (2/2) = 10/8 inches

3/8 inch remains the same.

Now we can subtract:

10/8 inches - 3/8 inch = (10 - 3)/8 inches = 7/8 inches.

Therefore, the difference in length between a 1 1/4-inch bottom and a 3/8-inch bottom is 7/8 inches.

First, regarding the simple way to find the horizontal asymptote.

The location of the horizontal asymptote depends on the function. For example, the function f(x) = 1/x has a horizontal asymptote at y=0.

The step-by-step answer

1. Identify the function's degree (highest power of x) in the numerator and the denominator.
2. Compare the degrees of the numerator and denominator:

  a) If the degree of the numerator is less than that of the denominator, the horizontal asymptote is y=0.
  b) If the degrees are equal, divide the leading coefficients to find the horizontal asymptote: y=(leading coefficient of numerator)/(leading coefficient of the denominator).
  c) If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.

For example, consider the function f(x) = (2x^2 + 3)/(x^2 - 5x + 6). The degrees of the numerator and denominator are both 2. Divide the leading coefficients: y = 2/1. So, the horizontal asymptote is y=2.

The value of b is degree 104.we can find by using vertically opposite theorem.

Vertical Angles are when two lines intersect each other then the opposite angles formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.The point where they meet is called a vertex.

Vertical opposite angles that are opposite each other when two lines cross are also known as vertical angles because the two angles share the same corner. Opposite angles are also congruent angles meaning they are equal or have the same measurement.

Now we have

(b-308)=(-2b+4)

b+2b=4+308

The area to the left of the z-score corresponds to the cumulative probability up to that point. The correct answer is b. z=0.84.

To find the z-score that separates the top 70% from the bottom 30%, we need to look up the corresponding percentile in a standard normal distribution table.

The area to the left of the z-score corresponds to the cumulative probability up to that point. For example, if we look up a z-score of 0.84 in the table, we find that the area to the left of that value is 0.7995, or 79.95%.

Since we want to find the value that separates the top 70% from the bottom 30%, we subtract 0.30 (or 30%) from 1.00 to get 0.70 (or 70%). We then find the z-score that corresponds to that area, which is approximately 0.84.

Therefore, the answer is b. z=0.84.

To find the Z-score value that separates the top 70% of a normal distribution from the bottom 30%, you need to look for the Z-score corresponding to the 70th percentile. In this case, the correct answer is:

b. z=0.52

Here's a step-by-step explanation:

1. Determine the percentile you're looking for, which is the 70th percentile (separating the top 70% from the bottom 30%).
2. Consult a Z-score table or use a calculator to find the Z-score corresponding to the 70th percentile.

The probability that all four defective bulbs will be obtained by the same person is 0.1140   .

In the question ;

it is given that

the total number of light bulbs in the box = 24 bulbs

total number of bulbs available for first person = 24 bulbs

number of defective bulbs = 4

So, the number of ways the first person can select 4 defective bulbs out of 10 selection = C(10,4)

total number of ways that first person can select 4 defective bulbs out of 24 bulbs  = C(24,4)

So , the Probability that all four defective bulbs obtained by first person = C(10,4)/C(24,4) . .......(i)

Since 10 bulbs have been selected

So, total number of bulbs available for second person = 14 bulbs

number of defective bulbs = 4

So, the number of ways the first person can select 4 defective bulbs out of 14 remaining bulbs = C(14,4)

total number of ways that first person can select 4 defective bulbs out of 24 bulbs  = C(24,4)

So , the Probability that all four defective bulbs obtained by second person = C(14,4)/C(24,4) . .....(ii)

Probability that all four of the defective bulbs will be obtained by the same person

The actual calculation depends on the specific vector field you are working with. You need to substitute the appropriate expressions for P and Q into the integrals and evaluate them accordingly.

To evaluate the line integral around the clockwise-oriented triangle with corners at the origin (0,0), (1,0), and (0,1), we need to sketch the vector field and the triangle and then calculate the integral.

Next, let's assume there is a vector field defined over the plane. Since you haven't provided the vector field explicitly, let's use a general notation and consider a vector field F = (P, Q), where P and Q are functions of x and y.

To calculate the line integral, we need to parameterize the triangle. We can divide the triangle into three line segments and parametrize each segment separately.

Line segment from (0,0) to (1,0):

Let's parameterize this segment as r(t) = (t, 0), where 0 ≤ t ≤ 1.

Line segment from (1,0) to (0,1):

Let's parameterize this segment as r(t) = (1 - t, t), where 0 ≤ t ≤ 1.

Line segment from (0,1) to (0,0):

Let's parameterize this segment as r(t) = (0, 1 - t), where 0 ≤ t ≤ 1.

Now, we can calculate the line integral for each segment and sum them up:

Line integral along the first segment:

\(\int(0 to 1) P(t, 0) dt + \int(0 to 1) Q(t, 0) dt\)

Line integral along the second segment:

\(\int(0\: to \:1) P(1 - t, t) dt + \int(0 \:to\: 1) Q(1 - t, t) dt\)

Line integral along the third segment:

\(\int(0 \:to \:1) P(0, 1 - t) dt + \int(0\: to \:1) Q(0, 1 - t) dt\)

Finally, the total line integral around the triangle is the sum of these three line integrals:

Total Line Integral = Line integral of segment 1 + Line integral of segment 2 + Line integral of segment 3

so if you want money and I give you 6dollers and remaining 4$it is 1. 1/4

Answer:

Step-by-step explanation:

The first step to solving this problem is to convert these into improper fractions.

\(7\frac{2}{3} =\frac{21+2}{3}=\frac{23}{3}\)

\(5\frac{1}{9} =\frac{45+1}{9}=\frac{46}{9}\)

The second step is to determine the reciprocal of the second term.

Reciprocal of \(\frac{46}{9} =\frac{9}{46}\)

The third step is to multiply the first term by the reciprocal of the second term.

\(\frac{23}{3}*\frac{9}{46}=\frac{207}{138}\)

The fourth step is to reduce this fraction.

\(\frac{207}{138}=\frac{3(69)}{3(46)}=\frac{23(3)}{23(2)}=\frac{3}{2}=1\frac{1}{2}\)

Answer:

1 1/2 or 3/2

Step-by-step explanation:

First you need to make your fractions improper.

7 times 3 + 2 = 23, so the fraction is 23/3

5 times 9 + 1 = 46, so the fraction is 46/9

Since this is division, flip the second fraction.

So instead of 46/9, it's now 9/46

Now you can multiply.

23/3 + 9/46 = 207/138

207/138 simplified is 3/2, or  1  1/2

The smallest possible area of the new rectangle is 52 square units.

In the question, we are given that a rectangle has side lengths of integral value.

We assume the lengths to be x and y units respectively, such that x and y are integers.

In the new arrangement, one pair is increased by 30%, and the other pair is decreased by 20%, such that the new sides are also integers.

We assume a 30% increase in x.

New side = x + 30% of x = x + 30/100 of x = x + 3x/10 = 13x/10.

For this to be an integer, x needs to be a multiple of 10.

Since we are considering the smallest area, we will consider the smallest multiple of 10, that is, 10 itself.

Hence, side 1 = 13 units.

We assume a 20% decrease in y.

New side = y - 20% of y = y - 20/100 of y = y - y/5 = 4x/5.

For this to be an integer, y needs to be a multiple of 5.

Since we are considering the smallest area, we will consider the smallest multiple of 5, that is, 5 itself.

Hence, side 2 = 4 units.

Now, the area of this rectangle is the product of its sides = 13*4 sq. units = 52 sq. units.
