Answer:

x=-1

Step-by-step explanation:

15x-5=12x-8 Simplify Parentheses

3x=-3 Isolate the variable

x=-1 Divide by 3 on both sides

Answer:

\(x=-1\)

Step-by-step explanation:

Our equation is

\(5\left(3x-1\right)=4\left(3x-2\right)\)

First, we distribute

Now we have

\(15x-5=12x-8\)

Subtract \(12x\) from both sides

\(3x-5=-8\)

add \(5\) to both sides

\(3x=-3\\\)

Divide both sides by 3

\(x=-1\)

The equivalent expression using the property is 10x + 16 = 8

This a property where a value is distributed over the values in parenthesis.

Given the following expression

2(5x+8) = 8

Using the Distributive property;

2(5x + 8) = 8

2(5x) + 2(8) = 8

10x + 16 = 8

Subtract 16 from both sides

10x = 8 - 16
10x = -8

x = -8/10

Hence the equivalent expression using the property is 10x + 16 = 8

Step-by-step explanation:

The wavelength λ1 for gamma rays of frequency f1 = 5.50×1021 Hz is 5.45 × 10-14 m.

To calculate the wavelength λ1 for gamma rays of frequency f1 = 5.50×1021 Hz, we can use the formula:
λ1 = c/f1

where c is the speed of light in a vacuum, which is approximately 3.00 × 108 m/s.
Substituting the values given, we get:

λ1 = 3.00 × 108 m/s / 5.50 × 1021 Hz
λ1 = 5.45 × 10-14 m

Therefore, the wavelength λ1 for gamma rays of frequency f1 = 5.50×1021 Hz is 5.45 × 10-14 m.

The number of possible ways you can distribute the balls among the three boxes so that each box contains at least one ball = 21

Here we have 3 empty boxes.

Let us assume that a, b and c be these empty boxes.

and the total number of balls = 8

We need to distribute the balls among the three boxes so that each box contains at least one ball.

This means that a + b + c = 8

By allotting 1 ball to each box so that no box remains empty.

We get an equation a + b + c = 5

So, the possible number of ways to by allotting 1 ball to each box so that no box remains empty would be:

∫sin^−1(x)/4x^2 dx = -(sin^−1(x)/4x) + (1/4) arcsin(x) + C.

et u = sin^−1(x)/4 and dv = 1/x^2 dx. Then, du/dx = 1/(4√(1-x^2)) and v = -1/x.

Using integration by parts formula, we have:

∫sin^−1(x)/4x^2 dx = uv - ∫v du/dx dx

= -(sin^−1(x)/4x) + ∫1/(4x√(1-x^2)) dx

= -(sin^−1(x)/4x) + (1/4)∫(1-x^2)^(-1/2) d(1-x^2)

= -(sin^−1(x)/4x) + (1/4) arcsin(x) + C

Therefore, ∫sin^−1(x)/4x^2 dx = -(sin^−1(x)/4x) + (1/4) arcsin(x) + C.

Answer:

x>24.75

Step-by-step explanation:

The given equation is :

\(\dfrac{-2}{5}x-9<\dfrac{9}{10}\)

Add 9 to both sides of the inequality.

\(\dfrac{-2}{5}x-9+9<\dfrac{9}{10}+9\\\\\dfrac{-2x}{5}<9.9\)

Multiply 5 to both sides of the inequality.

\(\dfrac{-2x}{5}\times 5<9.9\times 5\\\\-2x<49.5\)

Dividing both sides by(-2)

\(x<-24.75\)

or

\(x>24.75\)

Hence, the value of x is greater than 24.75.

The number of adult tickets that were sold would be = 435 tickets.

A ticket is an official document that gives an individual access to an event.

The cost of adult tickets = $8

The cost for student tickets = $4

The number of students tickets sold = X

The number of adults tickets sold = X +30

The told number of tickets sold = 840

To find X;

X + X + 30 = 840

2x + 30 = 840

2x = 840-30

2x = 810

X = 810/2

X = 405

Therefore, the number of tickets sold for adults = 405 +30 = 435 tickets.

The coefficient used to assess the internal consistency of a measure typically refers to Cronbach's alpha coefficient.

The coefficient used to assess the internal consistency of a measure typically refers to Cronbach's alpha coefficient. This coefficient is a statistic that quantifies the internal consistency reliability of a scale or measure, specifically for measures with multiple items or indicators that are intended to measure the same underlying construct.

The coefficient ranges between 0 and 1, with higher values indicating greater internal consistency. Cronbach's alpha measures the extent to which the items in a scale or measure correlate with each other. It assesses how well the items are measuring the same underlying construct or concept.

In other words, the coefficient represents the proportion of variance in the observed scores that can be attributed to the true score, rather than measurement error or other extraneous factors. It indicates the degree to which the items in the measure are interrelated or consistent with each other, with higher values suggesting stronger internal consistency.

Researchers often use Cronbach's alpha to assess the reliability of scales in various fields, such as psychology, education, and social sciences, to ensure that the measure is measuring the construct consistently and accurately.

\(Variance, s^2 = \dfrac{\sum(x-\overline{x})^2}{n-1}\)

For a larger input size of 320,000 elements, it will take 240 ms to sort each half and 24 ms to merge the sorted halves, resulting in a total time of 264 ms.

The given information describes the time required for sorting and merging operations on two different input sizes. For 80,000 elements, it takes 18 ms to sort each half, resulting in a total of 36 ms for sorting. Merging the two sorted halves with 80,000 numbers in each takes 40 - 18 = 22 ms.

When the input size is doubled to 320,000 elements, the sorting time for each half increases to 240 ms, as it scales linearly with the input size. The merging time, however, remains constant at 4 ms since the size of the sorted halves being merged is the same.

Thus, the total time for sorting and merging 320,000 elements is the sum of the sorting time (240 ms) and the merging time (4 ms), resulting in a total of 264 ms.

Therefore, based on the given information, the total time required for sorting and merging 320,000 elements is 264 ms.

A consumer advocacy group suspects that a local supermarket's 750 grams of sugar actually weigh less than 750 grams. The group took a random sample of 20 such packages, weighed each one, and found the mean weight for the sample to be 746 grams with a standard deviation of 8 grams. Using 10% significance level, would you conclude that the mean weight is less than 750 grams.

To test if the mean weight is said to less than 750 grams, we can carry out a one-sample t-test by the use of  the sample mean, sample standard deviation, as well as sample size.

The null hypothesis =  750 grams,

The  alternative hypothesis=  less than 750 grams.

so we need to calculate the test as:

t = (746 - 750) / (8 / √(20)) = -2.236

Next, we have to find the critical t-value for a one-tailed test with 19 degrees of freedom (so  n-1 =19)

When you a t-distribution table, the critical t-value to be -1.734.

Therefore, know that -2.236 < (less than) -1.734,  so you will reject the null hypothesis and say that the mean weight is less than 750 grams at a 10% significance level.

The equivalent expression is $\left(\dfrac{4^{3}}{5^{-2}}\right)^{5} = 102400000000000000000$.

We can simplify the expression inside the parentheses first:

\begin{aligned} \frac{4^3}{5^{-2}} &= 4^3 \cdot 5^2 \ &= (2^2)^3 \cdot 5^2 \ &= 2^6 \cdot 5^2 \ &= 2^5 \cdot 2 \cdot 5^2 \ &= 2^5 \cdot 10^2 \ &= 3200 \end{aligned}

Now we can substitute this value into the original expression and simplify further:

\begin{aligned} \left(\frac{4^3}{5^{-2}}\right)^5 &= (3200)^5 \ &= (2^8 \cdot 5^2)^5 \ &= 2^{40} \cdot 5^{10} \ &= (2^4)^{10} \cdot 5^{10} \ &= 16^{10} \cdot 5^{10} \ &= (16 \cdot 5)^{10} \ &= 80^{10} \ &= 102400000000000000000 \end{aligned}
