If you draw a card with a value of three or less from a standard deck of cards, I will pay you $208. If not, you pay me $35. (Aces are considered the highest card in the deck.) Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
The expected value of the proposition which is the net expected outcome is; $20.89.
How to find the expected value?We are given that;
There is a deck of cards.
There are 3 kinds of cards that have value under 4 (or equal). These 3 cards are 2, 3, 4 and they are in total 4 * 3 = 12 cards.
The probability that we draw such a card = 12/52 = 0.23.
Thus, the probability that we do not draw such a card = 1 - 0.23 = 0.77.
Now, If we play the game once, we will get 0.23 of the times $208 and 0.77 of the times $35.
Thus, the net total expected outcome is: (0.23*208) - (0.77*35)
= $20.89.

The number of songs that Deante' would have downloaded during month 9 is 58 songs.
What is a regression line?A regression line is a statistical line that best describes the behavior of a data set and such, it is a line that best fits a set of data.
By using Microsoft excel to plot the data on a scatter plot, we can logically deduce that line of best fit for the songs downloaded is given by:
y = 2.03x + 39.7
Thus, the number of songs that Deante' would have downloaded during month 9 is:
y = 2.03(9) + 39.7
y = 18.27 + 39.7
y = 57.97 ≈ 58 songs.

Given a population mean of 56.7, a standard deviation of 4.3, and a sample size of 260, what is the standard error of the mean? round
your answer to the nearest hundredth.
the standard error of the mean is approximately___.
The standard error of the mean, rounded to the nearest hundredth is 0.27
What is standard error of mean?The standard error of the mean (SEM) calculates how big of a difference there is between the mean of a sample and the mean of the population.
The square root of the sample size is divided by the standard deviation in order to obtain the Standard error of mean.
Always, standard error of mean will be smaller than standard deviation.
But a statistical inference based on the sampling distribution is part of the Standard error of mean definition.
According to the question,
Population Mean=56.7
Standard Deviation=4.3
Sample Size=260
Standard Error of mean=4.3/[tex]\sqrt{260}[/tex]

The sequence of transformations that can be
performed on quadrilateral ABCD to show
that it is congruent to quadrilateral GHIJ is
followed by a-
First transformation.
Duadrilateral ABCD has vertices with such coordinates:
A(15,10);
B(15,20);
C(20,15);
D(20,5).
Apply a rotation by 90°counterclockwise around point A to this quadrilateral, then
A(15,10)→A'(15,10);
B(15,20)→B'(5,10);
C(20,15)→C'(10,15);
D(20,5)→D'(20,15).
Second transformation.
1. A reflection across the y axis has a rule:
(x,y)→(-x,y).
Then
A'(15,10)→A''(-15,10);
B'(5,10)→B''(-5,10);
C'(10,15)→C''(-10,15);
D'(20,15)→D''(-20,15).
2. A translation 20 units down has a rule:

Here is a list of numbers: 13, 15, -6, 8, -16, 2, -12 ,3 ,-18 ,-18 state the median.
The median of list of numbers is-2.
Given the list of numbers is 13,15,6,8,-16,2,-12,3,-18,-18.
The median is the median of a sorted list of numbers. To find the median of a sequence of numbers, the numbers must be sorted in order from lowest to highest or highest to lowest.
Firstly, we will arrange the number from ascending to descending, we get
-18,-18,-16,-12,-6,2,3,8,13,15.
Now, we will find the middle term of the sequence, we get
The middle terms are -6 and 2.
Further, we will find the median of it.
n=(-6+2)/2
n=-4/2

work out the area of a rectangle with base, b = 20mm and perimeter, p = 50mm.
Answer:
100
Step-by-step explanation:
If the base is 20, then 2 of the sides must have a length of 20. This means that the TOTAL length of the remaining sides is 10. (20*2) + (10) = 50. If we divide that in half, we get 5. That is the side length of the remaining 2 sides. This means that 20 * 5 will give us the area (b*h).
Given,
base, b = 20mm &
perimeter, p = 50mm.
the area of the rectangle : (50 – 20 × 2) ÷ 2 = 5. 5 × 20 = 100 [tex]mm^{2}[/tex].
Perimeter and area are two important and basic mathematical subjects. They help quantify the physical space and also provide a more advanced foundation of mathematics in algebra, trigonometry, and calculus. Perimeter is a measure of the distance around a shape, and area indicates how much area the shape covers.
The perimeter of a 2D shape is the distance around the shape. You can imagine wrapping a string around a triangle. The length of this cord is around the triangle. Or, if you're traveling outside the park, take a route that goes around the edge of the park.

Answer:
[tex]\sf x = \dfrac{n - 2mp}{2m}[/tex]
Step-by-step explanation:
[tex]\sf 3m = m + \dfrac{n}{p + x}\\[/tex]
[tex]\sf 3m - m = \dfrac{n}{p +x}[/tex]
[tex]\sf 2m = \dfrac{n}{p +x}[/tex]
Now cross multiply,
2m*(p +x) = n
To open the parenthesis, multiply 2m by p and x.
2mp + 2mx = n
Isolate the term with variable 'x'
2mx = n - 2mp
Now, isolate 'x', by dividing both sides by 2m
[tex]\sf x = \dfrac{n-2mp}{2m}[/tex]
Answer:
x = [tex]\frac{N-2MP}{2M}[/tex]
Step-by-step explanation:
3M = M + [tex]\frac{N}{P+x}[/tex] ( subtract M from both sides )
2M = [tex]\frac{N}{P+x}[/tex] ( multiply both sides by P + x to clear the fraction )
2M(P + x) = N ← distribute parenthesis on left side
2MP + 2Mx = N ( subtract 2MP from both sides )
2Mx = N - 2MP ( divide both sides by 2M )
x = [tex]\frac{N-2MP}{2M}[/tex]

A population of protozoa develops with a constant relative growth rate of 0.469 per member per day. On day zero the population consists of five members. Find the population size after eight days.
If the growth rate is 0.469 per member per day and in the beginnning there are 5 members then the population size after eight days is 108.42.
Given growth of population of protozoa 0.469 per member per day and population in beginninng is 5 members.
We have to find the population afte eight days.
First of all we have to find the function or equation showing sum of population after t days.
Because it is given that the rate is 0.469 per member per day it means it is like compounding.
The equation which shows the sum after compounding is P[tex](1+r)^{n}[/tex]
where P is the amount in beginning, r is the rate and n is the number of years.
In this problem the equation will be 5[tex](1+0.469)^{t}[/tex] where t is number of days.
We have to put the value of t=8 to find the population after 8 days=
=5[tex](1.469)^{8}[/tex]
