what is 72% written in a deciamal

Answer:

\(q\geq -81\)

Step-by-step explanation:

First, begin by multiplying \(\frac{q}{27} \\\) by its reciprocal.

To do this, flip the fraction upside-down.

The resulting equation looks like this: \(\frac{27}{1} *\frac{q}{27}\)

Cancel out the two 27's and you are left with \(\frac{q}{1}\) , which you can simplify to q.

Next, multiply -3 by \(\frac{27}{1}\) . Remember, what you do on one side, you must do on the other.

Your equation should look like this:

\(q\geq -81\)

The final answer is \(q\geq -81\) .

Answer:

formula:

c^2 = a^2 + b^2 - 2abcos(C)

where c is the length of the diagonal, a and b are the lengths of the legs of the triangle (the non-parallel sides of the trapezoid), and C is the angle between them.

In this case, a = b = 7 feet and C = (180 - 140)/2 = 20 degrees. We can plug these values into the formula to find:

c^2 = 7^2 + 7^2 - 2(7)(7)cos(20)

c = sqrt(98 + 49cos(20))

To use the Law of Sines to find the length of the shorter base, we can use the following formula:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the sides of the triangle and A, B, and C are the angles opposite those sides.

Since we know a and b, we can use the formula to find:

x/sin(140) = 7/sin(20)

x = 7sin(140) / sin(20)

Note that the value of c will be in squared units, so you need to take the square root to get the actual length of the diagonal.

The situation that is best represented by an exponential distribution is given by the following option:

Tafadzwa runs between 10 and 16 laps every day. his times get slower as he gets tired, but his daily average is 48.2 s per lap. what is the probability that his mean lap time tomorrow will be less than 45 s?.

The exponential probability distribution, with mean m, is described by the following mass function:

\(f(x) = \mu e^{-\mu x}\)

In which \(\mu = \frac{1}{m}\) is the decay parameter.

From this, we get that the exponential distribution is used when we want to study the time between events in a distribution, and only the first option in this problem gives it.

As for the other options, the distributions are as follows:

The present value of the annuity is $4,813.52.

To calculate the present value of the annuity, we can use the formula for the present value of an increasing annuity:

PV = C * (1 - (1 + r)^(-n)) / (r - g)

Where:

PV = Present Value

C = Payment amount at time t=1

r = Interest rate

n = Number of payments

g = Growth rate of payments

In this case:

C = $300

r = 8% or 0.08

n = Number of payments = Last payment amount - First payment amount / Growth rate + 1 = ($1000 - $300) / $50 + 1 = 14

g = Growth rate of payments = $50

Plugging in these values into the formula, we get:

PV = $300 * (1 - (1 + 0.08)^(-14)) / (0.08 - 0.05) = $4,813.52

Therefore, the present value of this annuity is $4,813.52. This means that if we were to invest $4,813.52 today at an interest rate of 8%, it would grow to match the future cash flows of the annuity.

The difference quotient of f(x) is \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\) .

According to the given question.

We have a function

f(x) = -1/(5x -12)

As we know that, the difference quotient is a measure of the average rate of change of the function over and interval.

The difference quotient formula of the function y = f(x) is

[f(x + h) - f(x)]/h

Where,

f(x + h) is obtained by replacing x by x + h in f(x)

f(x) is a actual function.

Therefore, the difference quotient formual for the given function f(x)

= [f(x + h) - f(x)]/h

= \(\frac{\frac{-1}{5(x+h)-12} -\frac{-1}{5x-12} }{h}\)

= \(\frac{\frac{-1}{5x + 5h -12}+\frac{1}{5x-12} }{h}\)

= \(\frac{\frac{-1+5h}{5x + 5h-12} }{h}\)

= \(\frac{-1+5h}{(5x +h-12)(h)}\)

= \(\frac{-1+5h}{5xh + h^{2} -12h}\)

= \(\frac{h(-\frac{1}{h}+5) }{h(5x+h-12)}\)

= \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\)

Hence, the difference quotient of f(x) is \(\frac{-\frac{1}{h}+ 5}{5x+ h -12}\) .

The percentage of free moisture on a fine aggregate is 0.5%.

Free moisture refers to the moisture which is present on the surface of the aggregate after moisture has been absorbed and can be removed by drying the sand. Free moisture or free water is determined as the difference between the mass of wet-saturated aggregate sample and the mass of saturated-surface-dry condition sample.

Based on the given information:

Stock (present) weight = Weight of wet sample = 464.3g

Oven-dry weight = Weight of dry sample = 450.6g

Total Moisture = (Weight of wet sample - Weight of dry sample)/Weight of dry sample * 100

(464.3 – 450.6)/450.6 * 100 = 0.030 *100 = 3%

Step-by-step explanation:

Crout factorization is faster than Gaussian elimination because it takes advantage of the structure of a matrix and reduces the number of operations required to solve a system of linear equations.

In Crout factorization, the matrix is decomposed into a lower triangular matrix and an upper triangular matrix, which can be solved efficiently using forward and backward substitution.

This technique avoids the need for row interchanges, which are required in Gaussian elimination to avoid dividing by zero and to choose the largest pivot element. Row interchanges are computationally expensive because they require swapping entire rows of the matrix.

Additionally, Crout factorization is more numerically stable than Gaussian elimination because it produces a factorization that is less sensitive to rounding errors in the coefficients of the system of linear equations.

Answer:

∠ C = 100°

Step-by-step explanation:

since 2 sides of the triangle are congruent then the triangle is isosceles with base angles congruent.

consider the angle inside the triangle to the left of 140°

this angle and 140° are a linear pair and sum to 180°

angle + 140° = 180° ( subtract 140° from both sides )

angle = 40°

then the angle on the left of the triangle = 40° ( base angles congruent )

the sum of the angles in a triangle = 180° , so

∠ C + 40° + 40° = 180°

∠ C + 80° = 180° ( subtract 80° from both sides )

∠ C = 100°

The correct formula that defines an arithmetic sequence is option d) tn = 5n + 14.

An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms remains constant. In other words, each term can be obtained by adding a fixed value (the common difference) to the previous term.

In option a) tn = 5 + 14, the term does not depend on the value of n and does not exhibit a constant difference between terms. Therefore, it does not represent an arithmetic sequence.

Option b) tn = 5n² + 14 represents a quadratic sequence, where the difference between consecutive terms increases with each term. It does not represent an arithmetic sequence.

Option c) tn = 5n(n+14) represents a sequence with a varying difference, as it depends on the value of n. It does not represent an arithmetic sequence.

Option d) tn = 5n + 14 represents an arithmetic sequence, where each term is obtained by adding a constant value of 5 to the previous term. The common difference between consecutive terms is 5, making it the correct formula for an arithmetic sequence.

The number of megabytes downloaded is 51.1 megabytes

Percentage

In mathematics, a percentage is a number that is expressed as a fraction of 100. To find the percentage of a number in a whole number divide the given number by the whole number and multiply by 100. And the percentage is denoted by the symbol '%'.

For example,

Percentage of 5 in 20 = (5/20)×100 = 25%  = 25/100

Percentage of 2 in 40 = (2/40)×100 = 5% = 5/100

From the given problem,    

The size of the file is 287 megabytes

The percentage of the file downloaded = 17.8%

As we know percentage can express as a fraction

⇒ 17.8% = 17.8 /100

Therefore, the number of megabytes downloaded = 17.8% of 287 megabytes  

= (17.8 /100)× 287 megabytes

= (0.178) × 287 megabytes  

= 51.086  megabytes

Answer:

The answer is 15. First, you find the number that’s four more than six- 4+6=10. Next find the number that’s two thirds of ten. If one half of ten is five, multiply that by three, and you get 15.

For the polynomials p(x) = 1 - x + 4x² and q(x) = x - x², (p, q) = 10, ||p|| = √18, ||a|| = √18, and d(p, q) cannot be determined. For the vectors u = (0, 2, 3) and v = (2, 3, 0), (u, v) = 6, ||u|| = √13, ||v|| = √13, and d(u, v) cannot be determined.

In the first scenario, we have p(x) = 1 - x + 4x² and q(x) = x - x². To find (p, q), we substitute the coefficients of p and q into the inner product formula:

(p, q) = (1)(0) + (-1)(2) + (4)(3) = 0 - 2 + 12 = 10.

To calculate ||p||, we use the formula ||p|| = √((p, p)), substituting the coefficients of p:

||p|| = √((1)(1) + (-1)(-1) + (4)(4)) = √(1 + 1 + 16) = √18.

For ||a||, we can use the same formula but with the coefficients of a:

||a|| = √((1)(1) + (-1)(-1) + (4)(4)) = √18.

Lastly, d(p, q) represents the distance between p and q, which can be calculated as d(p, q) = ||p - q||. However, the formula for this distance is not provided, so it cannot be determined. Moving on to the second scenario, we have u = (0, 2, 3) and v = (2, 3, 0). To find (u, v), we use the given inner product formula:

(u, v) = (0)(2) + (2)(3) + (3)(0) = 0 + 6 + 0 = 6.

To find ||u||, we use the formula ||u|| = √((u, u)), substituting the coefficients of u:

||u|| = √((0)(0) + (2)(2) + (3)(3)) = √(0 + 4 + 9) = √13.

Similarly, for ||v||, we use the formula with the coefficients of v:

||v|| = √((2)(2) + (3)(3) + (0)(0)) = √(4 + 9 + 0) = √13.

Unfortunately, the formula for d(u, v) is not provided, so we cannot determine the distance between u and v.

The critical points of the function are (0, 0) and (3/4, -9/4), To classify the critical points, we need to examine the second partial derivatives of f(x, y) at each point

To find the critical points of the function f(x, y) = 8x^3 + y^2 + 6xy, we need to find the values of (x, y) where the partial derivatives with respect to x and y are equal to zero.

Taking the partial derivative with respect to x, we have:

∂f/∂x = 24x^2 + 6y = 0.

Taking the partial derivative with respect to y, we have:

∂f/∂y = 2y + 6x = 0.

Solving these two equations simultaneously, we get:

24x^2 + 6y = 0,

2y + 6x = 0.

From the second equation, we can solve for y in terms of x:

Y = -3x.

Substituting this into the first equation:

24x^2 + 6(-3x) = 0,

24x^2 – 18x = 0,

6x(4x – 3) = 0.

Therefore, we have two possibilities for x:

1. x = 0,

2. 4x – 3 = 0, which gives x = ¾.

Substituting these values back into y = -3x, we get the corresponding y-values:

1. x = 0 ⇒ y = 0,

2. x = ¾ ⇒ y = -9/4.

Hence, the critical points of the function are (0, 0) and (3/4, -9/4).

To classify the critical points, we need to examine the second partial derivatives of f(x, y) at each point. However, since the original function does not provide any information about the second partial derivatives, further analysis is required to classify the critical points.

Step-by-step explanation:

The sample that will produce the largest value for a t statistic is the one with the largest mean difference (MD) and the smallest sum of squares (SS). In this case, the sample with MD=10 and SS=20 would yield the largest t statistic value.

The magnitude of the t statistic in hypothesis testing is influenced by several factors, including the sample size, the mean difference between groups (MD), and the sum of squares (SS) within each group. However, other factors such as the variability of scores and the alpha level also play a role.

When comparing different samples with the same sample size of n=10, the sample that produces the largest t statistic will have a combination of a larger MD and a smaller SS. The MD reflects the difference in means between two groups or conditions, while the SS represents the variability or dispersion of scores within each group.

In this scenario, comparing the given options, the sample with MD=10 and SS=20 would result in the largest t statistic. This means that there is a greater difference between the means of the two groups and a relatively smaller variability within each group. A larger t statistic suggests a more significant difference between the groups, which strengthens the evidence against the null hypothesis.

It's important to note that the t statistic alone does not provide a complete understanding of the practical significance or effect size of the observed difference. Additional measures, such as confidence intervals or effect size calculations, should be considered to gain a more comprehensive interpretation of the findings.
