Step-by-step explanation:

The ordered triple representing \(3u - 2v\) is \((13, -8, 5)\).

To find an ordered triple representing \(3u - 2v\),

where \(u = (5, -2, 3)\) and \(v = (1, 1, 2)\),

we can perform the following operations:

\(3u = 3(5, -2, 3)\)

\(3u = (15, -6, 9)\)

\(2v = 2(1, 1, 2)\)

\(2v = (2, 2, 4)\)

Now, subtracting 2v from 3u gives:

\(3u - 2v = (15, -6, 9) - (2, 2, 4)\)

\(3u - 2v = (15-2, -6-2, 9-4)\)

\(3u - 2v = (13, -8, 5)\)

Therefore, the ordered triple representing 3u - 2v is (13, -8, 5).

Using the tangent of an angle from trigonometric ratios, the height of the tower is 45.15m

From the diagram of the situation, we can calculate the height of the tower using trigonometric ratios.

Assuming the distance apart the two wires is taken into consideration;

We can have a right - angle triangle.

Using tangent of an angle;

tan θ = opposite / adjacent

tan 62 = x / 24

cross multiply both sides

x = 24 tan 62

x = 45.15 m

What is division in algebra?

The four basic arithmetic operations of addition, subtraction, multiplication, and division are used to connect variables and constants in algebraic expressions. The procedure of multiplying and dividing algebraic expressions is the opposite of each other. You can divide algebraic expressions using the long division method, the division of a monomial by another monomial, or the division of a polynomial by another polynomial.

Dividend: The number or value that we divide is known as a dividend.

Divisor: The number that divides the dividend is known as a divisor

Quotient: The result obtained from the division process is known as a quotient

Remainder: The number left over after the division process is known as the remainder.

In the given question;

f(x) is dividend and

d(x) is divisor

Q(x) is the quotient

And we have to find the remainder i.e. R(x)

After dividing \(\frac{4x^3-8x^2+2x-1}{2x+1}\) we get

Q(x) =\(2x^2-5x\)

and R(x) = \(-[1-7x]\)

Answer: 9/2

Step-by-step explanation:

Given:

The equation is

\(\log_3625=x\)

To find:

The value of x.

Solution:

We have,

\(\log_3625=x\)

It can be written as

\(\log_3(5)^4=x\)

\(4\log_3(5)=x\)              \([\because \log x^n=n\log x]\)

\(4\dfrac{\log (5)}{\log (3)}=x\)               \([\because \log_ab=\dfrac{\log_xb}{\log_xa}]\)

\(4\times \dfrac{0.69897}{0.47712}=x\)

\(x\approx 5.8599\)

Therefore, the value of x is about 5.8599.

Mean vs Median

The mean (informally, the “average“) is found by adding all of the numbers together and dividing by the number of items in the set: 10 + 10 + 20 + 40 + 70 / 5 = 30.

The median is found by ordering the set from lowest to highest and finding the exact middle. The median is just the middle number: 20.

Answer:

\(t=\frac{(43.5 -40.1)-(0)}{3.678\sqrt{\frac{1}{20}+\frac{1}{20}}}=2.923\)

The degrees of freedom are

\(df=20+20-2=38\)

And the p value is given by:

\(p_v =2*P(t_{38}>2.923) =0.0058\)

Since the p value for this cae is lower than the significance level of 0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true means for this case are significantly different

Step-by-step explanation:

When we have two independent samples from two normal distributions with equal variances we are assuming that  

\(\sigma^2_1 =\sigma^2_2 =\sigma^2\)

And the statistic is given by this formula:

\(t=\frac{(\bar X_1 -\bar X_2)-(\mu_{1}-\mu_2)}{S_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}}\)

Where t follows a t distribution with \(n_1+n_2 -2\) degrees of freedom and the pooled variance \(S^2_p\) is given by this formula:

\(S^2_p =\frac{(n_1-1)S^2_1 +(n_2 -1)S^2_2}{n_1 +n_2 -2}\)

The system of hypothesis on this case are:

Null hypothesis: \(\mu_1 = \mu_2\)

Alternative hypothesis: \(\mu_1 \neq \mu_2\)

We have the following data given:

\(n_1 =20\) represent the sample size for group 1

\(n_2 =20\) represent the sample size for group 2

\(\bar X_1 =43.5\) represent the sample mean for the group 1

\(\bar X_2 =40.1\) represent the sample mean for the group 2

\(s_1=4.1\) represent the sample standard deviation for group 1

\(s_2=3.2\) represent the sample standard deviation for group 2

First we can begin finding the pooled variance:

\(\S^2_p =\frac{(20-1)(4.1)^2 +(20 -1)(3.2)^2}{20 +20 -2}=13.525\)

And the deviation would be just the square root of the variance:

\(S_p=3.678\)

The statistic is givne by:

\(t=\frac{(43.5 -40.1)-(0)}{3.678\sqrt{\frac{1}{20}+\frac{1}{20}}}=2.923\)

The degrees of freedom are

\(df=20+20-2=38\)

And the p value is given by:

\(p_v =2*P(t_{38}>2.923) =0.0058\)

Since the p value for this cae is lower than the significance level of 0.05 we have enough evidence to reject the null hypothesis and we can conclude that the true means for this case are significantly different

Using the t-distribution, as we have the standard deviation for the sample, it is found that the researcher can conclude that there is a difference between the population means at the 0.05 significance level.

At the null hypothesis, it is tested if there is no difference, that is:

\(H_0: \mu_1 - \mu_2 = 0\)

At the alternative hypothesis, it is tested if there is a difference, that is:

\(H_a: \mu_1 - \mu_2 \neq 0\)

For each sample, we have that they are given by

\(\mu_1 = 43.5, s_1 = \frac{4.1}{\sqrt{20}} = 0.9168\)

\(\mu_2 = 40.2, s_2 = \frac{3.2}{\sqrt{20}} = 0.7155\)

Hence, for the distribution of differences, the mean and the standard error are given by:

\(\overline{x} = \mu_1 - \mu_2 = 43.5 - 40.2 = 3.3\)

\(s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.9168^2 + 0.7155^2} = 1.163\)

It is given by:

\(t = \frac{\overline{x} - \mu}{s}\)

In which \(\mu = 0\) is the value tested at the null hypothesis, hence:

\(t = \frac{\overline{x} - \mu}{s}\)

\(t = \frac{3.3 - 0}{1.163}\)

\(t = 2.84\)

Considering a two-tailed test, as we are testing if the mean is different of a value, with a significance level of 0.05 and 20 + 20 - 2 = 38 df, the critical value is of \(|z^{\ast}| = 2.0244\).

Since the absolute value of the test statistic is greater than the critical value, it is found that the researcher can conclude that there is a difference between the population means at the 0.05 significance level.

Therefore, the package with 40 hooks is the better buy in terms of cost efficiency.

To determine which package is the better buy, we need to compare the cost per hook for each package.

For the package of 25 hooks costing $9.95, we divide the total cost by the number of hooks:

Cost per hook = $9.95 / 25 = $0.398

Rounding to the nearest cent, the cost per hook is $0.40.

For the package of 40 hooks costing $13.99, we divide the total cost by the number of hooks:

Cost per hook = $13.99 / 40 = $0.3498

Rounding to the nearest cent, the cost per hook is $0.35.

Comparing the two costs per hook, we can see that the package with 40 hooks for $13.99 offers a better deal, as the cost per hook is lower at $0.35.

Step-by-step explanation:

To find Bianca's walking speed, we need to divide the distance she walks by the time it takes her to walk that distance. We can do this by converting both the distance and time to the same unit of measure.

Since 1 hour is equal to 60 minutes, 1/3 of an hour is equal to 1/3 * 60 minutes = 20 minutes. Now that we have the distance in miles and the time in minutes, we can divide the distance by the time to find Bianca's walking speed.

5/6 of a mile is equal to 5/6 * 1 mile = 0.83 miles. So, Bianca's walking speed is 0.83 miles / 20 minutes = 0.0415 miles per minute. To convert this to miles per hour, we can multiply by the conversion factor of 60 minutes per hour. This gives us a walking speed of 0.0415 miles/minute * 60 minutes/hour = 2.49 miles per hour. So, Bianca's walking speed is 2.49 miles per hour.

If the test statistic is higher than 1.645, reject H0. If the test statistic is higher than 2.33, reject H0.

Conjectures used in statistical tests, which are formal techniques for drawing conclusions or making judgments based on data, include the null hypothesis and the alternative hypothesis.

The hypotheses, which are based on a sample of the population, are suppositions regarding a statistical model of the population.

The tests are essential components of statistical inference and are frequently used to distinguish between statistical noise and scientific claims when interpreting experimental data in science.

"The null hypothesis is the proposition under investigation in a statistical significance test.

The significance test is intended to determine how strong the evidence is against the null hypothesis. The null hypothesis is typically a claim that there is "no effect" or "no difference.
