Mean of the data = 83.92  

The term "mean" refers to the average of the data and is derived by dividing the total number of data observations in the data by the total number of observations.

It is a data point that represents the average of all the data points in the collection. The most popular and commonly applied approach in statistics for determining the middle of a data collection is the mean.  

Here given data is

No of students(f\(_{i}\))         4        3       9         2       3        3          4  

Score (x\(_{i}\))                     70      75     80       85      90      95      100

If a student is chosen at random, what is the probability of choosing a girl or an A student? ... I thought it would be B because we need to minus 3/30 probably that's both girl and A student.

Step-by-step explanation:

Answer:

Choice A

Step-by-step explanation:

First, let's simplify the equation. We get \(\frac{3^{-3}m^{6} n^{-3}}{6mn^{-2} }\) . Then, we can simplify. We now have \(\frac{3^{-3}m^{5} }{6n}\) . To get rid of the negative exponent, we multiply the top and bottom by 3^3 to get \(\frac{m^{2} }{6nx3^{3} }\). Note that the x in the denominator stands for multiplication. 3^3 = 27, so we have \(\frac{m^{5} }{6n(27)} = \frac{m^{5} }{162n}\)

Answer:

m^5/ 162 n

Step-by-step explanation:

( 3 m^-2 n) ^-3 / (6mn^-2)

We know a^ -b = 1/ a^b

1 / ( 3 m^-2 n) ^3 *(6mn^-2)

Distribute the power of 3

1 / ( 3^3 m^ -2 ^ 3 n^3) * ( 6m n^-2)

We know a^ b^ c = a^ ( b*c)

1 / ( 27 m^( -2 * 3) n^3) * ( 6m n^-2)

1 / ( 27 m^( -6) n^3) * ( 6m n^-2)

We know a^b * a^c = a^ ( b+c)

1 / ( 27*6 m^( -6+1) n^(3-2))

1/ (162 m^ -5 n^1)

We know a^ -b = 1/ a^b

m^5/ 162 n

Step-by-step explanation:

Jamie can text 11,702 words in 15 minutes found using the Cross-multiply method, found using the concept of proportions.

To find how many words can Jamie text in 15 minutes, we can use the concept of proportions. Here are the four possible proportions we can use to solve the problem:

1. Let's assume that x is the number of words Jamie can text in 15 minutes.

So, the proportion can be set up as:

312 words / 4 minutes = x words / 15 minutes

Cross-multiply the proportion to solve for x, we have:

312 × 15 = 4 × x

x = (312 × 15) / 4

= 1170

2. Let's assume that y is the number of minutes required by Jamie to text 312 words.

So, the proportion can be set up as:

y minutes / 312 words = 4 minutes / 1 word

Cross-multiply the proportion to solve for y, we have:

y = (312 × 4) / 1

= 1248

3. Let's assume that z is the number of minutes required by Jamie to text x words.

So, the proportion can be set up as:

312 words / 4 minutes = x words / z minutes

Cross-multiply the proportion to solve for z, we have:

312 × z = 4 × x

x = (312 / 4) × z = 78

z = 78 / x

4. Let's assume that w is the number of words Jamie can text in 1 minute. So, the proportion can be set up as:

312 words / 4 minutes = w words / 1 minute

Cross-multiply the proportion to solve for w, we have:

312 = 4w

w = 78

Therefore, Jamie can text 11,702 words in 15 minutes.

(a) The firm's output supply function is given by q = (p + 199) / 2.

(b) The market-equilibrium price is $32.56, and the equilibrium number of firms is 10.

(c) Each firm sells 70 computers in the long run.

(39 - 0.009q) = (2q - 2) / q

Simplifying the equation, we find:

q = (p + 199) / 2

This represents the firm's output supply function.

p = 39 - 0.009((p + 199) / 2)

Simplifying and solving for p, we get:

p ≈ $32.56

Substituting this price back into the output supply function, we find:

q = (32.56 + 199) / 2 ≈ 115.78

Given that each firm produces 70 computers in the long run, we can calculate the equilibrium number of firms:

Number of firms = q / 70 ≈ 10

70 * 10 = 700

Reconciling the Republican desire for equality for ex-slaves with the ex-Confederate desire for self-rule in the South was a significant challenge during the post-Civil War Reconstruction era.

Despite efforts to find common ground, the conflicting interests and deep-rooted divisions often made reconciliation difficult to achieve. The Republican Party aimed to ensure equality for ex-slaves through measures such as the Reconstruction Amendments, which granted civil rights and voting rights to African Americans. However, many ex-Confederates resisted these efforts, as they viewed them as an infringement on their right to self-rule and local autonomy. The concept of equality clashed with the ex-Confederate desire to maintain their social and political dominance in the South.

Various attempts were made to reconcile these conflicting desires, including the formation of biracial governments in some Southern states and the implementation of policies aimed at fostering cooperation and unity. However, these efforts faced significant resistance and were often undermined by persistent racial tensions, violence, and political maneuvering. Ultimately, the challenge of reconciling these competing interests highlighted the deep-seated divisions and difficulties in achieving a harmonious balance between equality for ex-slaves and the desire for self-rule in the post-Civil War South.

The graph at the end of the response provides the dilated figure, which has the same format as the original figure but reduced side lengths as a result of the dilation with a scale factor of less than 1.

To make an opening or hollow structure wider or larger than usual, such as a blood vessel or the pupil of an eye.

The process of dilation entails growing an object's size without changing its shape.

The size of the object may rise or decrease depending on the scale factor.

Using dilation maths, a square with a side of 5 units can be made wider to have a side of 15 units, yet the square retains its original shape.

So, the coordinates of each vertex of the figure are multiplied by the scale factors to create a dilatation in the image.

The vertices for the original figure that was graphed are listed as follows:

I(0,6).

H(3,6).

G(9,0).

F(-6,-9).

E(-6,-6).

The coordinates of the resulting image are presented as follows since the dilation has a scale factor of 1/3, which means that the coordinates are multiplied by 1/3:

I'(0,2).

H'(1,2).

G'(3,0).

F'(-2,-3).

Answer:

20 square yards

Step-by-step explanation:

Perimeter is l + l + w + w or 2l + 2w

Because these rectangles have the same perimeter they are equal.

Set them equal in an equation

2(9) + 2(3) = 2(l) + 2(2)

Simplify

18 + 6 = 2l + 4

24 = 2l + 4

Subtract 4 from both sides to isolate the variable l

20 = 2l

Divide both sides by 2

10 = l

So the length of the purple triangle is 10 yd

Area = l x w

Substitute in the values of the purple triangle

Area = 10 x 2

Area = 20 square yards

The probability of selecting exactly three clubs from a standard deck is 0.088. Where n = 5; p = 0.25; q = 0.75; and x = 3 . It is calculated by using binomial probability.

The binomial probability formula is

P(X = x) = ⁿCₓ pˣ q⁽ⁿ⁻ˣ⁾ = \(\frac{n!}{(n-x)!x!} p^xq^{(n-x)}\)

Where n is the number of trials, p i is the probability of success, and q is the probability of failure.

And q = 1 - p

It is given that, a card is selected from a standard deck and replaced.

This experiment has repeated a total of five times. i.e., trials n = 5

So, the probability of success is p = 1/4 = 0.25

(Since one card is to be selected from the five trials where each time the card is replaced)

Then, the probability of failure is q = 1 - 0.25 = 0.75

And it is given that we need to find the probability of selecting exactly three clubs. So, the required random variable is x = 3.

Then, using the binomial probability formula, we get

P(X = x) = ⁿCₓ pˣ q⁽ⁿ⁻ˣ⁾

⇒ P(X = 3) = ⁵C₃ p³q⁽⁵⁻³⁾ = ⁵C₃(0.25)³(0.75)² = 0.0878

On rounding off, we get the required probability as 0.088.

Ravi started with the improper fraction 25/4.

What is an improper fraction?

An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number). For example, 7/4 is an improper fraction because the numerator 7 is greater than the denominator 4.

To solve this problem, we need to work backwards from the mixed number 6 1/4 to the improper fraction that Ravi started with.

The whole number part of the mixed number, 6, represents six groups of the denominator. The fractional part, 1/4, represents one quarter of the denominator. So the mixed number 6 1/4 can be represented as:

6 + 1/4 = 6 x 4/4 + 1/4 = 24/4 + 1/4 = 25/4

Hence, Ravi started with the improper fraction 25/4.

(a) To determine if we can reject the null hypothesis that the means of the three treatments are equal, we can perform an analysis of variance (ANOVA) test. The test compares the variability between the treatment groups to the variability within the groups. The null hypothesis assumes that the means are equal, while the alternative hypothesis assumes that at least one mean is different. At the significance level of α = 0.05, we compare the calculated F-statistic to the critical F-value from the F-distribution with appropriate degrees of freedom. If the calculated F-statistic is greater than the critical F-value, we reject the null hypothesis. To perform this test, we need the sample means, sample variances, and sample sizes for each treatment group.

(b) Fisher's Least Significant Difference (LSD) procedure is used to test for significant differences between pairs of treatment means. The procedure calculates the LSD, which is the minimum difference required between two means to be considered statistically significant. We compare the absolute difference between two means to the LSD. If the absolute difference is greater than the LSD, we can conclude that there is a significant difference between the means. To perform this test, we need the sample means, sample variances, and sample sizes for the treatment groups.

(c) Fisher's LSD procedure can also be used to develop a confidence interval estimate of the difference between the means of treatments A and B. The confidence interval provides a range of values within which the true difference between the means is likely to fall. To calculate the confidence interval, we use the LSD, the sample means, sample variances, and sample sizes for treatments A and B. Using the formula for the confidence interval, we can determine the lower and upper bounds of the interval.

The implied forward rate of the euro in this situation is most closely approximated by option B, which is $1.5582.

The spot rate for the euro is given as $1.4700. The forward premium is 6.00%. To calculate the implied forward rate, we need to add the forward premium to the spot rate.

The forward premium is given as a percentage, so we need to convert it to a decimal by dividing it by 100. In this case, 6.00% is equal to 0.06.

To calculate the implied forward rate, we add the forward premium to the spot rate:

Implied Forward Rate = Spot Rate + Forward Premium

= $1.4700 + ($1.4700 * 0.06)

= $1.4700 + $0.0882
