The statement which is true is more males were surveyed than females, the correct option is A.

Suppose two dimensions are there, viz X and Y. Some values of X are there as X_1, X_2, ... , X_n and some values of Y are there as Y_1, Y_2, ... , Y_n

List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:

Value(ith row, jth column) = Frequency for intersection of  X_i  and Y_j  (assuming X values are going in rows, and Y values are listed in columns).

Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.

For n = 2, and k = 2, the table would look like:

[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]

where S denotes total of totals, also called total frequency.

n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.

We are given that;

            Males  Females  Total

Soccer      |  31   |    50   |  81

Basketball  |  21   |    50   |  71

Total       |  52   |   100   | 152

Now,

A. More males were surveyed than females.

True. From the table, we can see that 52 males were surveyed, while only 100 females were surveyed.

B. More females like soccer.

False. From the table, we can see that 31 males and 50 females like soccer, so a total of 81 people like soccer. This is the same as the number of females surveyed, so we cannot say that more females like soccer.

C. An equal number of people like soccer and basketball.

False. From the table, we can see that 81 people like soccer, while 71 people like basketball.

D. Twice as many females than males like basketball.

False. From the table, we can see that 21 males and 50 females like basketball. Twice the number of females who like basketball is 100, which is the total number of females surveyed, but this is not twice the number of males who like basketball.

Therefore, by the two-way table the answer will be more males were surveyed than females.

The empirical rule states that in a normal distribution, 68% of the observations lie within 1 standard deviation from the mean, 95% of the observations lie within 2 standard deviations from the mean, and , 99.7% of the observations lie within 3 standard deviations from the mean.

a) -  Mean = U = 330 grams

standard deviation= [tex]\sigma=40 \: grams[/tex]

As per the empirical rule, 68% of the observations lie within 1 standard deviation from the mean.

Let [tex]X_1[/tex] and [tex]X_2[/tex] be the 2 random value, between which 68% of the observations lie.

Mathematically,

[tex]X1=U-\sigma[/tex]

[tex]X1[/tex] = 330 - 40

[tex]X1[/tex] =  290

Similarly,

[tex]X1=U-\sigma[/tex]

[tex]X1[/tex] = 330 + 40

[tex]X1[/tex] = 370

Thus, about 68 % of organs will be between 290 and 370 grams in weight.

b) - In this, we need to find the percentage of organs weighing between 250 grams and 410 grams.

We can rewrite 250 as follows:

250= 330− 80 ⇒ 30−2(40) ⇒ 330−2(σ)

The above value (250) lies within 2 standard deviations from the mean.

Similarly,

We can rewrite 410 as follows:

410 = 330+80 ⇒ 330+2(40) ⇒ 330+2(σ)

The above value (410) lies within 2 standard deviations from the mean.\

As per the empirical rule, 95% of the observations lie within 2 standard deviations from the mean.

Thus, 95% of organs weighs between 250 grams and 410 grams.

c)-As we have calculated in part(b) that 95% of the organs lie within 250 and 410 grams.

So, area outside these values = Total area under curve - 95%

= 100 - 95 ⇒ 5%

So, 5% of the area lies outside the 250 and 410 grams range.

From the property of normal curve, we know that the area under the curve is divided into 2 equal parts.So, we divide the area- 5% into 2 equal parts which gives 2.5%.

The percent error of the measurement, to the nearest tenth of a percent, is 5.6.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

John measured a line to be 1.7 inches long.

The actual length of the line is 1.8 inches.

The amount of error = 1.8 - 1.7

The amount of error = 0.1

Let 1 - n be the required percentage of error.

Then applying the percentage formula,

1.8 x n /100 = 1.7

Applying cross multiplication,

we get,

1.8n = 170

n = 170/1.8

n = 94.4

So, 1 - n = 100 - 94.4 = 5.6

If A, B, and C are nxn invertible matrices, the equation   C^-1(A+X)B^-1=I(n) has a solution which is X=CB-A. Since invertible matrices are those whose inverse matrix exists.

For A to be the matrix  here A⁻¹ is the inverse of it, so AA⁻¹=I, here I is the identity matrix ,since the matrix equation given to us is: C⁻¹(A+X)B⁻¹=In, now multiplying B on the right side and  C on the left side we get :CC⁻¹(A+X)B⁻¹B=CIₙB

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

The Zucchini will be longer than 11 feet on the ninth day.

Since 12 inches is equal to 1 foot, then 11 feet will be equal to 132 inches. Below, we are going to describe the rate of the plant's growth from day 1.

Day 1 = 6 inches

Day 2 = 6 + 9 inches = 15 inches

Day 3 = 15 + 9 + 3 = 27 inches

Day 4 = 27 + 12 + 3 = 42

Day 5 = 42 +15 + 3 = 60

Day 6 = 60 + 18 + 3 = 81

Day 7 = 81 + 21 + 3 = 105

Day 8 = 105 + 24 + 3 = 132

Day 9 = 132 + 27 + 3 = 162

We are told that on the second day, the tree grew up to 15 inches and subsequently, it grew by the same amount as the day before plus another three inches.

Going by that calculation, on the third day, the tree will grow by 9 inches plus three more inches and this continues. Finally, on the ninth day, the tree would have grown up to 162 inches which is greater than 132 inches or 11 feet.

Answer:

Step-by-step explanation:

Prim's algorithm is a greedy algorithm used to find the minimum spanning tree (MST) of a connected, undirected graph. It works by growing the tree one vertex at a time, always adding the vertex with the lowest weight edge that connects it to the growing tree. The algorithm starts with an arbitrary vertex, adds it to the tree, and then repeats the following steps until all vertices are in the tree:

Find the vertex that is not in the tree but has the minimum weight edge connecting it to the tree.

Add the vertex to the tree and mark it as visited.

Update the minimum weight edges connecting the vertices that are not yet in the tree to the growing tree.

This process continues until all vertices are in the tree, and the final result is the minimum spanning tree. The visualization of Prim's algorithm for minimum spanning tree can be represented graphically by showing the growth of the tree one vertex at a time, and highlighting the edges that are added to the tree in each step. The animation can be used to show how the algorithm is making decisions based on the weights of the edges and how it is gradually building the minimum spanning tree.

The Laplace inverse is not a standard function on most calculators. However, if you have a graphing calculator that supports Laplace transforms, you can use it to find the Laplace inverse by performing the inverse Laplace transform on a function.

Here's the general procedure for finding the Laplace inverse on a graphing calculator:

Enter the Laplace transform of the function you want to find the inverse of.

Select the inverse Laplace transform function from the calculator's menu.

Enter the desired complex variable, usually represented by "s" in Laplace transform notation.

The calculator will return the inverse Laplace transform of the function, which represents the original function in the time domain.

Note: The exact steps for finding the Laplace inverse on a graphing calculator will vary depending on the model and brand of the calculator. It's best to consult the manual or a reference guide for your specific calculator to determine how to perform the inverse Laplace transform.

The measure of angle C in radians is 3.6 radians.

The arc length of a circle is defined as the interspace between the two points along a section of a curve. An arc of a circle is any part of the circumference. The angle subtended by an arc at any point is the angle formed between the two line segments joining that point to the end-points of the arc.

Given that, the circle has a radius of 7 and angle C intercepts the arc with a length of 28π.

We know that, formula to find the arc length of circle is Arc length= θ/360 ×2πr

28π= θ/360×2π×7
