Which of the following is the best description of the shape and center of the dotplot? The distribution of math classes is skewed left with a center around 4 classes. The distribution of math classes is skewed left with a center between 3 and 4 classes. The distribution of math classes is unimodal symmetric with a center around 4 classes. The distribution of math classes is unimodal symmetric with a center between 3 and 4 classes.

Answers

The best description of the shape and center of the dotplot is that distribution of math classes is unimodal symmetric with a center around 4 classes. The Option C is correct.

How do we identify that distribution of classes is unimodal symmetric on dotplot?

A dot plot shows the frequency of each value in a dataset. To identify if the distribution of classes is unimodal symmetric, we will check if the dots are roughly evenly distributed around a central line which is the 4 classes.

This indicates the distribution is symmetric. We have a single peak in the data. If there is only one prominent cluster of dots, then, the distribution is unimodal. So, the distribution of classes is unimodal symmetric on the dot plot.

Answer:

mass of 50 L of R = 15p + 35q

Step-by-step explanation:

1L of P = p g

1L of Q = q g

R = 3P + 7Q

total = 10

P = 3/10 R

Q = 7/10 R

R = 50 L

50 L × 0.3 = 15 L the amount of P in L

15 L of P = 15p g

35 L 0f Q = 35 q g

then

mass of 50 L of R = 15 p + 35 q grams

Answer:

The value of AM = 43

Step-by-step explanation:

As point M is the midpoint of AB, so

AB = AM + BMAM = BM

Given

AB = 8x - 50

AM = 2x + 9

so substituting AB = 8x - 50 and AM = 2x + 9 in the equation AB = AM + BM

AB = AM + BM

8x - 50 = 2x + 9 + BM

8x - 2x - 50 - 9 = BM

6x - 50 = BM

Thus,

BM = 6x - 59

AM = BM

so substituting AM = 2x + 9 and BM = 6x - 59 in the equation AM = BM

2x + 9 = 6x - 59

switch sides

6x - 59 = 2x + 9

subtract 2x from both sides

6x - 2x - 59 = 2x + 9 - 2x

4x - 59 = 9

add 59 to both sides

4x - 59 + 59 = 9 + 59

4x = 68

divide both sides by 4

4x/4 = 68/4

x = 17

Thus, the value of x = 17

Therefore, the value of AM will be:

AM = 2x + 9 = 2(17) + 9 = 34 + 9 = 43

Hence, the value of AM = 43

Verification:

AM = BM

2x + 9 = 6x - 59

2(17) + 9 = 6(17) - 59

34 + 9 = 102 - 59

43 = 43

and

AB = 8x - 50 = 8(17) - 50 = 86

Let the long-run profit function for a representative firm is given by π i

=p 2
−2p−399, where p is the price of computer. The inverse market demand for computer is given by p=39−0.009q, where q is unit of computers. Suppose technology for producing computers is identical for all firms and all firms face identical input prices. (a) Find the firm's output supply function. (b) Find the market-equilibrium price and the equilibrium number of firms. (c) Find the number of computers sold by each firm in the long run.

Answers

(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.

To find the firm's output supply function, we need to maximize the firm's profit function, which is given by π = p^2 - 2p - 399. In the long run, firms will produce where marginal cost equals marginal revenue. Marginal revenue can be obtained by differentiating the inverse market demand function with respect to q, and marginal cost is equal to the derivative of the profit function with respect to q. Equating the two, we get:

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

Simplifying the equation, we find:

q = (p + 199) / 2

This represents the firm's output supply function.

To find the market-equilibrium price and the equilibrium number of firms, we need to find the intersection point of the market demand and supply. Substituting the output supply function into the inverse market demand function, we have:

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

Since each firm sells 70 computers in the long run, and there are 10 firms, the total number of computers sold by each firm is:

70 * 10 = 700

OLAP is used for the analysis of accumulated data, and it requires a data warehouse.

while OLTP is used for transaction processing and requires a database optimized for real-time transaction processing. The analysis of accumulated data is known as Online Analytical Processing (OLAP), and it involves a data warehouse. OLAP is a business intelligence tool used for multi-dimensional analysis of large data sets, while a data warehouse is a central repository that stores historical and current data from multiple sources in a structured manner. OLAP allows users to perform complex queries on large data sets, analyze trends, and make informed business decisions. It is often used in data mining and decision support systems. OLAP tools can be used to slice and dice data, drill down to more detailed data, and roll up to higher levels of summary data. OLAP is primarily used for analytical purposes and is not designed for transaction processing. On the other hand, a data warehouse is designed to support OLAP and is used for storing large amounts of historical data that can be queried and analyzed.

In a grade with 164 students,there were 18 more girls than boys. How many girls were in the grade?

Answers

Answer:

Step-by-step explanation:

Let us set boys as x. Girls would then be x+18

Girls and Boys together would be x + x+ 18

Therefore,

x+x+18=164

2x+18=164

2x=146

x=73

Since girls are x + 18, they would be 73 + 18, or 91.

I hope this helps! :)

Answer:

There were 91 girls.

Sophia was asked to find the original dimension of a reduced hexagon. A smaller hexagon has a top side length of 1.2 inches and bottom side length of x inches. A larger hexagon has a top side length of 7.2 inches and bottom side length of 9 inches. Sophia found that the enlarged hexagon’s dimensions were just 6 more than the original hexagon, thus x = 3. What was Sophia’s error? Sophia should have found the number the dimensions were multiplied by. Sophia should have divided 9 and 6 . Sophia should have set up a proportion to solve for x. Sophia should have multiplied 7.2 and 1.2. Sophia is correct and did not make an error.

Ecological approach to algal bloom control. Algal blooms can have negative effects on an ecosystem by dominating its phytoplankton communities. Gonyostomum semen is a nuisance alga infesting many parts of northern Europe. Could the overall biomass of G. semen be controlled by grazing zooplankton species? A research team examined the relationship between the net growth rate of G. semen and the number of Daphnia magna grazers introduced in test tubes. A net growth rate was computed by comparing the initial and final abundances of G. semen in the experiment, with a negative value indicating a decrease in abundance. Here are the findings: 13 1 2 3 4 5 6 Number of grazers Net growth rate -1.9 -2.5 -2.2 -3.9 -4.1 -4.3 a. Make a scatterplot of number of grazers and net growth rate. Do you think that D. magna is an effective grazer of the G. semen alga? b. Find the correlation 1. How does it support your interpretation?

Answers

a. D. magna is an effective grazer of the G. semen alga. b. a very strong negative correlation between the number of grazers and the net growth rate of G. semen.

a. The scatterplot of the data shows a clear negative correlation between the number of D. magna grazers and the net growth rate of G. semen. As the number of grazers increases, the net growth rate of G. semen decreases. This suggests that D. magna is an effective grazer of the G. semen alga.

b. The correlation coefficient between the number of grazers and the net growth rate is -0.996. This indicates a strong negative correlation between the two variables, which supports the interpretation that D. magna is an effective grazer of G. semen. The closer the correlation coefficient is to -1, the stronger the negative correlation between the two variables. In this case, the correlation coefficient is very close to -1, which indicates a very strong negative correlation between the number of grazers and the net growth rate of G. semen.

Using probability of union set,

the probability that person you choose is either a woman or has never been married is 0.66..

We have given that

If X be random variable that an American adult selected.

Assume that

A : selected adult is a women

B : selected adult has never married

Probability that you choose a woman, P(A) = 0.52

Probability that the person you choose has never been married , P(B) = 0.25

Probability that you choose a woman who has never been married , P(A∩B) = 0.11

we have to calculate probability that person you choose is either a woman or has never been married, P(A∪B)

Using the formula,

P(A∪B ) = P(A) + P(B) - P(A∩B)

pluging all known values in above formula we get

=> P(A∪B ) = 0.52 + 0.25 - 0.11

=> P(A∪B) = 0.77 - 0.11 = 0.66
