By the Application of Prime factorization method the value of x is 48

what is Prime factorization method?

Writing all numbers as the product of primes is a procedure known as prime factorization. Consider the case of the number 20, for instance. We can divide that into two elements. Well, that's four times five, we can say. Furthermore, 5 is a prime number.

Solution:

HCF = ( X, 54 ) = 6

LCM = ( X, 54 ) = 432

a = x  b = 54

using property

a * b = LCM * HCF

54a = 6 * 432

   a  = (6 * 432) / 54

   a = 48

Hence the value of x is 48.

Answer:

p = -8 6/35

Step-by-step explanation:

p/(1 6/7)=−4.4

To solve for p, multiply each side by 1 6/7

p/(1 6/7) * ( 1 6/7)=−4.4 *  (1 6/7)

p = - 4.4 * ( 1 6/7)

Change each number to fractions

p = -44/10 * 13/7

p = -286/35

Change to a mixed number

p = -8 6/35

The critical value is -2.70

What is a null hypothesis?

Two alternatives being the same is the null hypothesis. The underlying assumption is that the observed difference is just the result of chance. It is feasible to estimate the probability that the null hypothesis is correct using statistical testing.

Here, we have

The objective of this experiment is to compare two compounds, designed to reduce braking distance, used in tire manufacturing to prove if the braking distance of SUVs equipped with tires made with compound 1 is shorter than the braking distance of SUVs equipped with tires made with compound 2.

So you have 2 independent populations, SUV's equipped with tires made using compound 1 and SUVs equipped with tires made using compound 2.

Two samples of 66 braking tests are made and the braking distance was measured each time, the study variables are determined as:

X₁: Braking distance of an SUV equipped with tires made with compound one.

Its sample mean is X[bar]₁= 41 feet

And the Standard deviation S₁= 12.1 feet

X₂: Braking distance of an SUV equipped with tires made with compound two.

Its sample mean is X[bar]₂= 46 feet

And the Standard deviation S₂= 9.0 feet

We don't have any information on the distribution of the study variables, nor the sample data to test it, but since both sample sizes are large enough n₁ and n₂ ≥ 30 we can apply the central limit theorem and approximate the distribution of both variables sample means to normal.

The researcher's hypothesis, as mentioned before, is that the braking distance using compound one is less than the distance obtained using compound 2, symbolically: μ₁ < μ₂

The statistical hypotheses are:

H₀: μ₁ ≥ μ₂

H₁: μ₁ < μ₂

α: 0.05

The statistic to use to compare these two populations is a pooled Z test

Z= {(X[bar]₁-X[bar]₂) - (μ₁ - μ₂)}/√S₁²/n₁+S₂²/n₂ ≈ N(0;1)

Z = {(41-46)-0}/√146.41/66+81/66

Z = -5/1.85

Z = -2.70

The rejection region of this hypothesis test is one-tailed to the right, so you'll reject the null hypothesis to small values of the statistic. The critical value for this test is:

Z(α) = Z(0.05) = -1.645

Decision rule:

If Z(H₀) ≥  -1.645, then you do not reject the null hypothesis.

If Z(H₀) < -1.645, then you reject the null hypothesis.

Since the statistic value is greater than the critical value, the decision is to not reject the null hypothesis.

At a 5% significance level, you can conclude that the average braking distance of SUVs equipped with tires manufactured used compound 1 is greater than the average braking distance of SUVs equipped with tires manufactured used compound 2.

Hence, the critical value is -2.70.

Answer: 304

Step-by-step explanation:

The probability that there were at most three successes in a trial is approximately 0.9.

It looks like the histogram shows the probability mass function (PMF) for the number of successes in a trial. The PMF for a random variable gives the probability of each possible value of the random variable.

To find the probability that there were at most three successes in a trial, we need to add up the probabilities of 0, 1, 2, and 3 successes. From the histogram, it looks like the probabilities of these values are approximately 0.2, 0.4, 0.2, and 0.1, respectively. Adding these up, we get an approximate probability of 0.2 + 0.4 + 0.2 + 0.1 = 0.9.

Therefore, the probability that there were at most three successes in a trial is approximate $\boxed{0.9}$.

What is exponential growth factor?

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

(x + 1)/(x + 4)

Factoring an algebraic expression specifically means writing a given expression as the product of its factors. These factors may be numbers, variables, or algebraic expressions.

1, 2, 6, and 12 are all divisors of 12 because they divide 12 equally. This is an important algebraic operation, which is used to simplify expressions, simplify fractions, and solve equations. This is also called algebraic factorization.

Factorization of x² + 2x - 3

x² + 3x - x - 3

(x² + 3x) - (x + 3)

x(x + 3) - 1(x + 3)

(x + 3)(x - 1)

Factorization of x² + 3x - 4

x² + 4x - x - 4

(x² + 4x) - (x + 4)

x(x + 4) - 1(x + 4)

(x + 4)(x - 1)

Factorization of x² - 2x - 3

x² - 3x + x - 3

(x² - 3x) + (x - 3)

x(x - 3) + 1(x - 3)

(x - 3)(x + 1)

Using identity, a² - b² = (a + b)(a - b)

x² - 9 = x² - 3²

x² - 3² = (x + 3)(x - 3)

Now, for the division:

(x² + 2x - 3)/(x² - 9) ÷ (x² + 3x - 4)/(x² - 2x - 3)

[(x + 3)(x - 1)/(x + 3)(x - 3)] ÷ [(x + 4)(x - 1)/(x - 3)(x + 1)]

By reciprocal of (x + 4)(x - 1)/(x - 3)(x + 1)

[(x + 3)(x - 1)/(x + 3)(x - 3)] × [(x - 3)(x + 1)/(x + 4)(x - 1)]

according to question,

given data.

h(x)=8x-3/4+5

then,

The cost of a 25-minute rental will be $92.00.

To find the amount a 25-minute rental would cost, we need to first determine the rate per minute and the flat fee. We can do this by setting up the following system of equations:

30 minutes x rate + flat fee = $110.50

40 minutes x rate + flat fee = $145

To solve this system of equations, we can multiply the first equation by 2 and subtract the second equation from it to eliminate the rate:

(30 minutes x 2) x rate + flat fee x 2 = 2 x $110.50

80 minutes x rate + flat fee x 2 = 2 x $110.50

Subtracting the second equation from the first equation, we get:

flat fee x 2 - flat fee x 2 = 2 x $110.50 - 2 x $145

flat fee x 2 - flat fee x 2 = -$34.50

Since the left side of the equation is equal to zero, we can divide both sides by 2 to solve for the flat fee:

flat fee - flat fee = -$34.50 / 2

flat fee - flat fee = -$17.25

Since the left side of the equation is also equal to zero, the flat fee must be zero.

We can now use either of the original equations to solve for the rate per minute. Using the first equation, we get:

30 minutes x rate + flat fee = $110.50

30 minutes x rate = $110.50

rate = $3.68

We can now use this rate to find the cost of a 25-minute rental:

25 minutes x $3.68 + flat fee = $92.00 (Since the flat fee is zero)

Thus, a rental of 25 minutes costs $92.00.

This function is continuous at every point in its domain, which is the set of all real numbers (-infinity < x < infinity). However, at the point x = 0, the function is discontinuous.

At x = 0, the function f(x) = x^2 is equal to 0, but if we approach the point x = 0 from the left (x = -0.1, -0.01, etc.), the function is equal to a negative value (-0.01, -0.0001, etc.), and if we approach the point x = 0 from the right (x = 0.1, 0.01, etc.), the function is equal to a positive value (0.01, 0.0001, etc.). This means that the function is not continuous at the point x = 0, and is therefore discontinuous at this point.

The point of discontinuity in this example is an essential discontinuity, which means that it cannot be removed by redefining the function at that point.

The equation for the relationship between the number of cans of paint, x, and the total weight of the cans, y, in slope-intercept form is y = 6x + 0. This equation can be derived from the formula for the slope-intercept form of a line, y = mx + b, where m is the slope of the line and b is the y-intercept. In this case, since the weight of each can of paint is 6 pounds and there is no y-intercept (the line passes through the origin), the slope of the line is 6 and the y-intercept is 0.

A table of possible values for the number of cans of paint, x, and the total weight of the cans, y, based on this equation is shown below:

x (number of cans of paint) y (total weight of cans)

1 6

2 12

3 18

4 24

5 30

As the table shows, for each additional can of paint, the total weight of the cans increases by 6 pounds. This is because each can of paint weighs 6 pounds, and the weight of the cans is equal to the number of cans multiplied by the weight of each can.

Answer: y = 6x

Step-by-step explanation:

       For each can of paint (x) 6 pounds is added. This is represented as;

         y = 6x

       For the table of possible values, we will plug a value in for x, and then evaluate the function for y. See attached.

To solve a problem involving a whole number and a fraction, you can first convert the whole number to a fraction by writing it as a fraction with a denominator of 1. For example, if the whole number is 4, you can write it as the fraction 4/1.

Then, you can add or subtract the fractions as you would normally, making sure to find a common denominator if necessary. For example, suppose you want to add the whole number 4 and the fraction 3/5. You can first write 4 as the fraction 4/1, giving you:

4/1 + 3/5

To add these fractions, you need to find a common denominator. A common denominator for 1 and 5 is 5, so you can rewrite the fractions with denominators of 5:

4/1 = 20/5

3/5 = 3/5

Now you can add the fractions:

20/5 + 3/5 = 23/5

So the solution to the problem is 23/5.

If you need to multiply or divide the whole number and fraction, you can treat the whole number as a fraction with a denominator of 1 and then perform the multiplication or division as you would normally with fractions.

The values of x, y and z are 24, 10 and 17 using the similar triangles properties and triangles sum properties.

A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.

Given that ΔHPS≅ΔCNF.

We can see that angle H in triangle HPS is obtuse whereas angle N in triangle CNF is obtuse so comparing this we get,

6x - 29 = 115

6x = 144

x = 24

Comparing angle C and angle P we get

4z - 32 = 36

4z = 68

z = 17

Now the remaining angle in trinagle CNF is angle F which is 3y - 1 as we know that sum of angles in a triangle is 180 and the angle C and N are 36 and 115 we can say that F  is  29

Now to find y we equalise it to 29

3y - 1 = 29
