Given that P(A)=0.8 and P(B|A)=0.31, find the joint probability P(A and B):
============================================
Work Shown:
P(A and B) = P(A)*P(B|A)
P(A and B) = 0.8*0.31
P(A and B) = 0.248
The notation P(B|A) means "Probability of B given A". It's the same as "P(B) given event A has happened". It is conditional probability notation. The symbol between the A and B is a vertical line and not a letter.
does y=6x+5 represent a function? explain your answer
Yes, y = 6x + 5 is linear function.
Given that,
To explain does y = 6x+5 represent a function.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
y = 6x + 5, represents the line,
comparing it with the standard from the equation of the line,
y = mx + c
After comparing
m = = 6 and c = 5
And also for every value of independent variable x, there is a distinct value of dependent variable y.
Thus, Yes, y = 6x + 5 is linear function.

Find the 11th term of the following geometric sequence.

Step-by-step explanation:
A child shot a toy rocket into the air from their playhouse which stood 5 ft above the ground. The rocket rose to 50 ft above the ground and landed on the ground 3.4 seconds later. The path of the toy rocket could be modeled by a quadratic function, h(t), where h is the height of the toy rocket in feet after t seconds.
(1) What is the practical domain of the function?
(2) What is the practical range of the function?
(3) How would the theoretical domain and range of the function differ from the practical domain and range of the situation?
Answer:
Part A)
All real numbers between 0 and 3.4 (including 0 and 3.4).
Part B)
All real numbers between 5 and 50 (including 5 and 50).
Part C)
See below.
Step-by-step explanation:
We know that the rocket rose to a maximum of 50 feet and was in the air for 3.4 seconds. The rocket started at a height of 5 feet.
Part A)
The practical domain of a function is the domain with the context. Here, our domain is the number of seconds that had passed. Time can't be negative, so our domain must be greater than or equal to 0. Also, since we know that our rocket landed after 3.4 seconds, this means that our practical domain is all real numbers between 0 and 3.4 including 0 and 3.4.
Part B)
The practical range of a function is the range with the context. Here, our range is the height the rocket reaches. We know that the rocket started at a height of 5 feet, so our practical range should be greater than or equal to 5. We also know that the maximum height the rocket reached was 50 feet. So, our practical range is all real numbers between 5 and 50 including 5 and 50.
Part C)
The theoretical domain and range differs from the practical domain and range in that the theoretical counterparts don't consider the context. For the theoretical domain and range, we will analyze this as a normal quadratic. Since it's a quadratic, the theoretical domain is all real numbers. Since our maximum value is y=50, our theoretical range is all numbers less than or equal to 50.
However, this can't be used since negative time (e.g. height after -2 seconds) is inapplicable and negative height doesn't make sense in this context either (well, technically negative height can indicate that the rocket goes underground, but this is not mentioned here).
So, it is important to determine when to use practical domain/range and theoretical domain/range!

f(n +1 ) =f(n) +6
f(n +1 )=2 f(n)
f(n +1) = f (n) +2
f(n + 1) = 1.5f(n)
Answer: f(n+1) =f(n)+2

To make a flour mixture, a miller combines soybeans that cost $8 50 per bushel with wheat that costs $4.50 per bushel. How many bushels of each did he use if his final 800 bushel mix cost $5.50 per bushel?
Answer:
200 bushels soybeans
600 bushels wheat
Step-by-step explanation:
If s is bushels of soybeans, and w is bushes of wheat, then:
s + w = 800
8.5s + 4.5w = 5.5(800)
Substitute:
8.5s + 4.5(800 − s) = 5.5(800)
8.5s + 3600 − 4.5s = 4400
4s = 800
s = 200
w = 600

s+1/4s=-6-3/2
provide your answer
Answer:
s = -6
Step-by-step explanation:
Combining terms, we get ...
(5/4)s = -15/2
Multiplying by 4/5 gives ...
s = (4/5)(-15/2)
s = -6
a product code consists of picking a two-digit number (including 00) and 3 not necessarily distinct letters. How many codes are possible? how many codes contain at least one 9? What is the probability that a code does not contain the number 9?
Answer:
The codes are:
N,_,_,_
Where each _ represents a possible letter, out of 26.
And N is a number of two digits.
So in total we can think that we have 5 empty slots.
_,_,_,_,_
In the first slot we can put any digit between 0 and 9, so here we have 10 options.
In the second slot we can put any digit between 0 and 9, so here we have 10 options.
In the third slot we can put any letter, so here we have 26 options (and exactly the same for the fourth and fifth slots)
The total number of different combinations is equal to the product of the number of options for each slot.
C = 10*10*26*26*26 = 1,757,600
Now, if we want to have at least one nine, we can fix it in the first slot.
Then we have:
in the first slot we have only one option (the 9)
In the second slot we can put any digit between 0 and 9, so here we have 10 options.
In the third slot we can put any letter, so here we have 26 options (and exactly the same for the fourth and fifth slots)
The number of combinations is:
C = 1*10*26*26*26 = 175,760
But we also should consider the case where we fix the 9 in the second slot, so the actual number of combinations is twice the number above.
C = 2*175,760 = 351,520
The probability that the code does not contain the number 9.
Now in the first slot we have only 9 options, all the whole numbers between 0 and 8.
The same for the second slot, 9 options.
For the third, fourth and fifth slot is the same as before.
The total number of combinations is:
C = 9*9*26*26*26 = 1,423,656

The length of a rectangle is six more than double the width. If the perimeter is 102 inches find the dimensions
Answer:
width = 15 inches
length = 36 inches
Step-by-step explanation:
To solve you need to find the width...
width = w
length = 2w + 6
the perimeter is all the way around the area, so..
2w + 2(2w + 6) = 102
because there are 2 widths and 2 lengths in a perimeter.
Solve for w:
2w + 4w + 12 = 102
subtract 12 from both sides and combine like terms...
6w = 90
divide both sides by 6...
w = 15
the width = 15, and the length = 2(15) + 6 = 36
What is 3(w+4)= -2(1.5-6).
Answer:
w = -1
Step-by-step explanation:
3(w + 14) = -2(1.5 - 6)
3w + 12 = -3 - (-12)
3w + 12 = 9
-12 -12
3w = -3
÷3 ÷3
w = -1

Find the value C(-2), where C is defined below.
C(x) = -3x2 – 3x - 3
Answer:
C(-2) = -9
Step-by-step explanation:
Step 1: Define
C(x) = -3x² - 3x - 3
C(-2) = x = -2
Step 2: Substitute and Evaluate
C(-2) = -3(-2)² - 3(-2) - 3
C(-2) = -3(4) + 6 - 3
C(-2) = -12 + 6 - 3
C(-2) = -6 - 3
C(-2) = -9
