Josie read 40 pages of a book in 50 minutes. How many pages could she read in two hours?​

Answer:

Yes

Step-by-step explanation:

The only relevant information is each side of the pentagonal pyramid is 9 years and so the perimeter of the base is 45 since 9 x 5 = 45 yards.

The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = ? According to this property, you can add the numbers and then multiply by 3.

To determine the convergence or divergence of an alternating series, you can use the Alternating Series Test. This test states that if the terms of an alternating series decrease in absolute value and approach zero, then the series converges.

Additionally, if the terms do not approach zero, the series diverges.

To apply the Alternating Series Test, you need to check two conditions:

1. The terms of the series must alternate in sign.

2. The absolute value of the terms must decrease or approach zero.

If both conditions are satisfied, you can conclude that the alternating series converges. However, if either condition fails, the series diverges.

If you want to determine the convergence or divergence more precisely, you can use the Integral Test or the Comparison Test. The Integral Test allows you to compare the convergence or divergence of a series to the convergence or divergence of an improper integral. If the integral converges, the series converges, and if the integral diverges, the series diverges.

The Comparison Test is another method to determine the convergence or divergence of a series. It involves comparing the given series with a known series whose convergence or divergence is already known. If the known series converges and the terms of the given series are less than or equal to the corresponding terms of the known series, then the given series also converges. Conversely, if the known series diverges and the terms of the given series are greater than or equal to the corresponding terms of the known series, then the given series also diverges.

Answer:

Perpendicular

Step-by-step explanation:

Remember that:

So, let's find the slope of QR and ST.

QR)

We can use the slope formula:

\(m=\frac{y_2-y_1}{x_2-x_1}\)

Let Q(-6, 11) be (x₁, y₁) and R(2, -1) be (x₂, y₂). Substitute:

\(m=\frac{-1-11}{2-(-6)}\)

Subtract:

\(m=-12/8=-3/2\)

So, the slope of QR is -3/2.

ST)

Let S(-4, 8) be (x₁, y₁) and T(-1, 10) be (x₂, y₂). Substitute:

\(m=\frac{10-8}{-1-(-4)}\)

Subtract:

\(m=2/3\)

So, the slope of ST is 2/3.

The negative reciprocal of -3/2 is 2/3.

And the negative reciprocal of 2/3 is -3/2.

So, the slopes are indeed negative reciprocals of each other.

So, QR and ST are perpendicular.

The decision for this test at a .05 level of significance is not enough information to make a decision the correct answer is (d).

To make a decision for a hypothesis test, we compare the obtained test statistic (in this case, z = 1.80) with the critical value(s) based on the chosen level of significance (in this case, α = 0.05).

For a one-sample z test, if the obtained test statistic falls in the rejection region (i.e., beyond the critical value(s)), we reject the null hypothesis. Otherwise, if the obtained test statistic does not fall in the rejection region, we fail to reject the null hypothesis.

Without knowing the critical value(s) corresponding to a significance level of 0.05 and the directionality of the test (one-tailed or two-tailed), we cannot determine the decision for this test. Therefore, the correct answer is (d) There is not enough information to make a decision.

Answer:

I seem to be late but I feel like the answer is X = 12.

Step-by-step explanation:

I will start out with my expression .

First step i take is adding 3 to both sides of the expression. \(\sqrt{x} +4 - 3+3 = 1 + 3\) . This leaves me with \(\sqrt{x}+4 = 4\).

My second step I will need to remove the check mark thingy away from the expression. In order for me to do that, I am going to have to square both sides of the expression giving me this!  \(\sqrt{x} +4^{2} = 4^{2} = x +4 = 16\) .

Now for my final step which will be to remove 4 from both sides of my expression. X + 4 – 4 =16 – 4 = x = 12.

True, different sequences of row operations can lead to different echelon forms for the same matrix.

When performing row operations on a matrix to bring it to echelon form, the order in which the operations are applied can affect the resulting echelon form. The goal of row operations is to manipulate the matrix to have zeros below certain pivots, creating a triangular structure. However, there can be multiple valid sequences of row operations that achieve this goal, resulting in different echelon forms.

The specific sequence of row operations can vary depending on the choices made during the elimination process. For example, the choice of pivot elements and the order in which rows are swapped can differ, leading to different arrangements of zeros and nonzero elements in the echelon form. However, regardless of the sequence of row operations, the resulting echelon form will share fundamental properties such as having leading entries (pivots) strictly to the right of the leading entries in the rows above.

Answer: Without knowing the specific problem you are referring to, it is impossible to determine the equation for the inverse function m(p).

However, in general, to find the inverse function of a given function f(x), we can follow these steps:

Replace f(x) with y: y = f(x)

Swap x and y: x = f(y)

Solve for y: y = f^-1(x)

The resulting equation y = f^-1(x) represents the inverse function of f(x).

For example, if the function f(x) = 2x + 5, the inverse function can be found as follows:

Replace f(x) with y: y = 2x + 5

Swap x and y: x = 2y + 5

Solve for y: y = (x - 5) / 2

Therefore, the inverse function of f(x) = 2x + 5 is f^-1(x) = (x - 5) / 2.

Answer:

No, the relation R^2 is not necessarily irreflexive.

Step-by-step explanation:

The relation R^2 represents the composition of the relation R with itself. In other words, it consists of pairs (a, c) such that there exists an intermediate element b for which (a, b) and (b, c) are both in R.

Even if the relation R is irreflexive (meaning there are no pairs (a, a) in R), the relation R^2 can still contain pairs (a, a) if there exists an intermediate element b such that (a, b) and (b, a) are both in R. In this case, (a, a) would be in R^2, violating the condition for irreflexivity.

Therefore, the relation R^2 can have reflexive elements even if the relation R is irreflexive.

The score interval that is within one standard deviation of the mean is

(70 , 80).

What is standard deviation?

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean of the collection.

Some of the properties of the standard deviation are:

1. It cannot be negative

2. It is only employed to calculate the spread or dispersion around a data set's mean

3. It displays the degree of deviation  from the mean value

4. The larger the spread, the more standard deviation, with data of about the same mean.

Given,

 The mean of the test μ = 75

The standard deviation σ = 5

We are asked to find the scores within one standard deviation of the mean.

This means that the scores should be in the interval ( μ - σ , μ + σ )

μ - σ = 75 - 5 =70

μ + σ = 75 + 5 = 80

Therefore the scores should be in the interval = ( 70,80), which is within one standard deviation of the mean.

The median number of newspapers sold over seven weeks is 223.

The median is the middle score for a data set arranged in order of magnitude. The median is less affected by outliers and skewed data.

The formula for the median is as follows:

Find the median number of newspapers sold. (87, 87, 215, 154, 288, 235, 231)

We'll first arrange the data in ascending order.87, 87, 154, 215, 231, 235, 288

The median is the middle term or the average of the middle two terms. The middle two terms are 215 and 231.

Median = (215 + 231)/2

= 446/2

= 223

In statistics, the median measures the central tendency of a set of data. The median of a set of data is the middle score of that set. The value separates the upper 50% from the lower 50%.

Hence, the median number of newspapers sold over seven weeks is 223.
