Answer:

Mean = 260.45

Median = 284

Mode = 287, 285  (there are 2 modes)

Since it is a championship sports team , it is likely that this data is representative of all players in that league

Step-by-step explanation:

Mean = Sum of the weights/11 = 2865/11 = 260.45

Median is the middle of the data set when the data values are arranged in ascending order

In ascending order: 206, 216, 217, 235, 273, 284, 285, 285, 287, 287, 290

Mode is the value that occurs the maximum number of times in a data set

Here there are 2 modes 285 and 287 both of which occur twice

The gram and kilogram are two units used to measure mass in the metric system .

We need to find the metric unit to find mass of a book.

The resistance that a body of matter offers to a change in its speed or position upon the application of a force.

1 kilogram of a substance is equal to 1000 grams and 1 gram is equal to 0.001kg. Therefore, to convert the mass of a book weighing 12,321g into kg, we will multiply it by 0.001kg. The book's mass in kg is 12.321 kg.

Therefore mass is measured by kilogram or grams.

There are no real solutions for the equation x² + 20 = 4.

Equation, which is defined as the quality of being equal, is frequently represented by a mathematical expression with equal values on either side or by a situation in which numerous factors must be taken into account.

Consider the equation,

x² + 20 = 4

Subtracting 20 from each side of the equation.

x² + 20 - 20 = 4 - 20

x² = - 16

√x² = √ - 16

x = ± √-16

x = ± 4√(-1)

x = ± 4i

Since i is the complex number that is equal to √-1. Therefore, there are no real solutions to the equation.

The volume of the toy box is 24 cubic feet.

Remember that for a rectangular prism of length L, width W, and height H the volume is given by the formula:

V = L*W*H

In this case, we know that:

L = 4ft

W = 3ft

H = 2ft

Replacing that in the volume formula we get.

V = 4ft*3ft*2ft = 24ft^3

The area of the shaded region in the first quadrant is: 0.75 units

The area under a curve between two points can be found by doing a definite integral between the two points.

Now,

Given:

To find: area bounded by the given lines and curve in the first quadrant.

Finding:

Now, according to the question, the lines x = 0 and y = 2 intersect at the point (0,2).

Point of Intersection of y = 2 and y = 3x - x²:

2 = 3x - x²

=> x² - 3x + 2 = 0

=> (x - 2)(x - 1) = 0

That is, the line and the curve intersect at two points: ( 1 , 2) and (2,2). But the point that is of our importance is only (1,2).

Thus, area shaded = [tex]\int\limits^1_0 {2 - 3x +x^{2}} \, dx[/tex] = 0.75 square units.

According to the given statement One and half hour after the summer thunderstorm began, the temperature was approximately 1.0°F flower than at the start of the storm.

Subtract the final temperature from the starting temperature to get the temperature change (T). Multiply the temperature change by the sample's mass. Share the product's energy and heat output.

The equation is C = Q / (T m).

Consider the function t as defined below. t(h)=9.5h – 15.52 +17.4h-10.12

Here,

h is the number of hours after storm began.

The function t represents the rate of change of temperature in °F per hour during the hour and a half after the storm began.

During the storm, the temperatures lowers and then rises.

One and half hour after the summer thunderstorm began, the temperature was approximately 1.0°F flower than at the start of the storm.

Answer:

60°

Step-by-step explanation:

since it is an equilateral triangle all sides are equal. let's make the other 2 angles k.

k+k+k=180°{sum of angles in a triangle}

3k=180°

k=60°(each of them is 60°)

Answer:

2

Step-by-step explanation:

18x -12 = 18x -12 +2

18x -12 = 18x -10

18x cancel each other out

-12 = -10

-12 + 12 = -10 + 12

add 12 to each side

= 2

By using properties of right triangles, we will see that the value of x is 7.72

In the image we have a set of right triangles, and we want to find the value of x.

Let's look at the large triangle in the left, we know that the hypotenuse measures 18 units and one angle measures 64°, with that information we can get the adjacent side (the dashed line, let's call it A) to that angle:

Cos(64°) = A/18

18*cos(64°) = A = 7.05

Now we know one of the cathetus of the smaller right triangle (the one we can see in the right side). Here we know one angle that measures 20° and the opposite to that angle measures 7.05

Then the value of x is given by the equation:

x = 7.05/sin(20°) = 7.72

We conclude that the value of x is 7.72

The chances that the student was merely guessing is 1/3.

Bayes Theorem determines the conditional probability of an event A given that event B has already occurred.

denoted by

let A be the  event that the student knows the answer .

B be  the  event that the student does not knows the answer .

and

E be the event he gets answer correct .

According to the given question

[tex]P(A)=\frac{4}{10} \\\\ P(B)=1-\frac{4}{10} =\frac{6}{10}[/tex]

Probability that the answer is correct ,given that he knows the answer is

[tex]P(E/A)=1[/tex]

Probability that the answer is correct ,given that he guesses it is

[tex]P(E/B)=\frac{1}{3}[/tex]   [as the MCQ has 3 options and only one is correct]

We need to find the probability that he guesses the answer given that it is correct.

Required probability [tex]P(B/E)=\frac{P(B)*P(E/B)}{P(A)*P(E/A)+P(B)*P(E/B)}[/tex]

Substituting the values we get

[tex]P(B/E)=\frac{\frac{6}{10} *\frac{1}{3} }{\frac{4}{10} *1+\frac{6}{10} *\frac{1}{3} }[/tex]

[tex]=\frac{6}{30}*\frac{30}{18} \\ \\ =\frac{6}{18} \\ \\ =\frac{1}{3}[/tex]

As per the question:

No. of pea cans in a case = 18 cans

Weight of each can of peas = 12 ounces

Price of a case of peas = $14.22

The information regarding the weight of each can is redundant in this question and therefore, is not used for solving the question

Therefore, the formula to be used for solving:

Price per unit can of peas= (Price of a case of peas/No of pea cans in a case)

Price per unit can of peas= ($14.22/18)

The price per unit can of peas= $0.79
