In a test (+5)marks are give for every correct answer and (-2)marks for every incorrect answer. Jay answered all questions and scored (-12)m though he got four correct answer)how many incorrect answer he attempted
Answers
Answer:
32 incorrect answers was attempted by JayStep-by-step explanation:
Let the amount of correct answer gotten be x and that of wrong answer be y. The sum of Jay score = 5x+ (-2)y [since(+5)marks are give for every correct answer and (-2)marks for every incorrect answer]
If Jay answered all questions and scored (-12)m, then 5x - 2y = -12
If Jay got four answers correctly, the number of correct answers x = 4
Substituting x = 4 into the equation 5x - 2y = -12 to get the value of y, we will have;
5(4) - 2y = -12
20 - 2y = -12
-2y = -12-20
-2y = -32
y = 16
This means that Jay attempted 16 incorrect answers.

Answers
Answer:
Set; subset.
Step-by-step explanation:
A group of objects or numbers is called a set while a part of a set is called a subset. The objects or numbers that make up a set are generally referred to as elements or members and are written inside a pair of curly braces {}.
A set can be made up of elements such as numbers, alphabets, people, cars etc.
For instance, Set A = {2, 4, 6, 8, 10, 12} represents all the even number between 1 - 12.
On the other hand, a subset is a part of a larger set.
For instance, comedy movies, horror movies, romance movies, action movies are a subset of movies.

Let,
Mass of the steel be 108xMass of the copper be 7xThen, Total mass = 108x + 7x = 115xGiven,
Total mass of the coin = 230 mgThat means,
⇛ Total mass of the coin = 230 mg
⇛ 115x = 230 mg
⇛ x = 230 mg/115
⇛ x = 2 mg

If the 11th term of a geometric sequence is 32 times larger than the 6th term, then
what is the common ratio of the sequence
Answers
Answer:
r = 2
Step-by-step explanation:
nth term of a geometric sequence = [tex] ar^{n - 1} [/tex].
Where,
a = first term, r = common ratio,
We are given that, the 11th term is 32 times larger than the 6th term of the geometric sequence. Thus:
the 6th term can be expressed as [tex] ar^{n - 1} = ar^{6 - 1} [/tex]
[tex] a_6 = ar^{5} [/tex]
The 11th term is expressed as [tex] a_11 = ar^{10} [/tex]
Since the 11th term is 32 times larger than the 6th term, therefore, the following equation can be derived to find the common ratio, r, of the sequence:
[tex] a_11 = 32*a_6 [/tex]
[tex] a_11 = ar^{10} [/tex]
[tex] a_6 = ar^{5} [/tex], therefore:
[tex] ar^{10} = 32*ar^{5} [/tex]
Divide both sides by ar⁵
[tex] \frac{ar^{10}}{ar^5} = \frac{32*ar^{5}}{ar^5} [/tex]
[tex] r^5 = 32 [/tex]
[tex] r^5 = 2^5 [/tex]
[tex] r = 2 [/tex]
Common ratio = 2

a. What is the probability that a california adult is an internet user, given that he or she is a college graduate?
b. Among California adults, what is the probability that a randomly chosen internet user is a college graduate?
Answers
Answer:
Step-by-step explanation:
a) The probability that a california adult is an internet user, given that he or she is a college graduate can be represented with the following
P(internet user|college graduate) = P(internet user ∩ college graduate) P(college graduate) = 0.19/26= 0.7307
= 0.73
b) The probability that a randomly chosen internet user is a college graduate?
P(college graduate|internet user) = P(internet user ∩ college graduate) P(internet user) = 0.19/0.31= 0.6129
= 0.61

Answers
Answer:
S = 60
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
S + 3(2 + x) = -36
Step 2: Define variables
x = 6
Step 3: Plug in variables
S + 3(2 + 6) = -36
Step 4: Parenthesis
S + 3(8) = -36
Step 5: Multiply
S + 24 = -36
Step 6: Subtract 24 on both sides
S = 60
hey does anyone know the answer to this? Alexa agreed to pay back her friend $10 per week and originally borrowed $170.
Answers
Answer:
L(t) = 170 - 10t
Step-by-step explanation:
Alexa borrowed some money from her friend in order to help buy a new video game system. Alexa agreed to pay back her friend $10 per week and originally borrowed $170. Write an equation for L, in terms of t, representing the amount Alexa owes her friend after t weeks.
Let
Initial amount Alexa borrowed= L(o)
Amount Alexa pays per week= k
Number of weeks= t
Amount Alexa owes her friend after t weeks= L(t)
The amount that Alexa owes after t weeks is given by the equation:
L(t) = L(o) - kt
Where,
L(o) = $170
k= $10
Substituting the values into the equation, we have,
L(t) = L(o) - kt
L(t) = 170 - 10t
Therefore,
The amount Alexa owes her friend after t weeks is given by
L(t) = 170 - 10t
Suppose you Just purchased a used truck. The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it. Write this equation using function notation, f(x).
Answers
Answer: [tex]f(x)= x+40000[/tex]
Step-by-step explanation:
We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".
Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.
Here y is dependent on x, so we replace y by f(x), then we get
[tex]f(x)= x+40000[/tex] which is the required answer.

1. Rick renovated his home. He made his bedroom 40% larger (length and width) than its original size. If the original dimensions were 144 inches by 168 inches, how big is his room now if measured in feet?
Answers
Answer:
New dimension: 16.8 feet by 19.6 feet.
Step-by-step explanation:
Given that,
The original dimensions of the room were 144 inches by 168 inches. Rick renovated his home. He made his bedroom 40% larger than its original size.
40% of 144 = 57.6
New length is 144 + 57.6 = 201.6 inches
40 % of 168 = 67.2
New breadth is 168 + 67.2 = 235.2 inches
Since, 1 foot = 12 inch
201.6 inches = 16.8 feet
235.2 inches = 19.6 feet
The new dimension of the room is 16.8 feet by 19.6 feet.

Mary wants to put a fence around her garden. The garden measures 10 feet by 6 feet. If fencing costs $5 per foot, how much will the fence cost Mary?
Answers
First, find the cost of how much fence Mary needs per side.
10 * 5 = 50
10 * 5 = 50
6 * 5 = 30
6 * 5 = 30
Second, add all together.
50 + 50 + 30 + 30 = 160
Therefore, the total cost of the fence will be $160.
