Five cards (a hand) are dealt from a randomly shuffled deck of cards. For those of you that are not familiar with playing cards: each card has a suit (hearts, spades, diamonds, clubs) and a symbol (aces, kings, queens, etc.). The deck contains a total of 52 cards, with 13 of each suit and 4 of each symbol. What is the probability that the hand contains a) all spades
Answer: 0.0004951
Step-by-step explanation:
Given
Five cards are from the deck
The total number of cards in the deck is 52
total spades card is [tex]13[/tex]
We have to choose 5 cards out of 13, this can be done in
[tex]\Rightarrow ^{13}C_5[/tex]
The probability of choosing 5 spade cards is
[tex]\Rightarrow P=\dfrac{^{13}C_5}{^{52}C_5}\\\\\Rightarrow P=\dfrac{1287}{2598960}=0.0004951[/tex]
A clothing business finds there is a linear relationship between the number of shirts, n (in thousands) it can sell and the price, P, it can charge per shirt. In particular, historical data shows that 3 thousand shirts can be sold at a price of $69 each, and that 7 thousand shirts can be sold at a price of $61 each. Find the equation of the form P(n)
Answer:
The equation of the form P(n) is:
P(n)=-0.002n+75
Step-by-step explanation:
From the information provided, you have two points: (3000, 69) and (7000, 61). With this, you can find the slope using the following formula:
m=(p1-p2)/(n1-n2)
m=slope
p1=69
p2=61
n1=3000
n2=7000
m=(69-61)/(3000-7000)
m=8/-4000
m=-0.002
Now that you have the slope, you can find the the equation of the form P(n):
P(n)=-0.002(n-3000)+69
P(n)=-0.002n+6+69
P(n)=-0.002n+75
According to this, the answer is that the equation of the form P(n) is:
P(n)=-0.002n+75

In(x^4)=6
Answer:
The solution is [tex]x = 4.4817[/tex]
Step-by-step explanation:
The inverse of the ln function is the exponential, which means that to solve this question, we apply the exponential to both sides.
We have that:
[tex]\ln{(x^4)} = 6[/tex]
Applying exponential to both sides:
[tex]e^{\ln{(x^4)}} = e^6[/tex]
[tex]x^4 = e^6[/tex]
[tex]x = \sqrt[4]{e^6}[/tex]
[tex]x = (e^6)^{\frac{1}{4}}[/tex]
[tex]x = 4.4817[/tex]
The solution is [tex]x = 4.4817[/tex]
please help!!!!! Its timed !!!!! Ill give out most brainly and extra points !!!
Answer:
A)15Step-by-step explanation:
to understand thisyou need to know about:equationPEMDASlet's solve:parimeter of a square:4a
according to the question
[tex] \sf 4(8x + 2) = 488[/tex]
divide both sides by 4:
[tex] \sf \frac{4(8x + 2) }{2}= \frac{488}{2} \\ \sf \frac{ \cancel4 ^{} (8x + 2)}{ \cancel{4}} = \frac{ \cancel{488} \: ^{122} }{ \cancel{ \: 2}} \\ 8x + 2 = 122[/tex]
cancel 2 from both sides:
[tex] \sf 8x + 2 - 2 = 122 - 2 \\ \sf 8x = 120[/tex]
divide both sides by 8
[tex] \sf\frac{8x}{8} = \frac{120}{8} \\ \sf \therefore \: x = 15[/tex]

Brainliest?
Answer:
0 = 0
Step-by-step explanation:
Subtract 4 from both sides of the equation
3 + 4 − 4 = 3 + 4 − 4
Simplify
Subtract the numbers
3 = 3 + 4 − 4
3 = 3
Subtract 3x from both sides of the equation
3 − 3 = 3 − 3
Combine like terms
0 = 3 − 3
Result
0 = 0

As part of a demographic study, a college administrator needed to survey a sample of students from the college. From each major offered at the college, the administrator randomly selected 5 percent of the students with that major to participate in the survey. Which of the following is the best description of the type of sample selected by the administrator?
a)cluster sample
b)convenience sample
c)simple random sample
d)stratified random sample
e)systematic random sample
Answer:convenient I think
Step-by-step explanation:
Saw the first 5 people with the major at the time
The best description of the type of sample selected in the question is;
Option D; Stratified Random Sample
We are told that for the demographic study, the college administrator randomly selected 5% of the students with the particular major randomly.
Since they were chosen randomly, it is clear that this is a type of random sampling that was not done with a convenient sample. Thus, Options A and B are already out of it leaving us with C, D or E
Let us look at the options;
Option C; This sample cannot be a simple random sample because since only 5% are selected from each major, all the students don't have equal chance of being chosen.Option D; This sample is a stratified random sample because the population has been divided into smaller groups by their majors.Option E; This cannot be a systematic random sample because there is no fixed period or interval of selection done.Read more at;https://brainly.com/question/1954758
