A card is drawn from a well-shuffled deck of 52 cards. What is the probability of drawing an ace or a 6?A. 13/2B. 7/26C. 6/52D. 2/13
Answers
Step 1
State the expression for the probability of an event to occur.
\(\text{The probability of an event =}\frac{number\text{ of required events}}{\text{Total number of events}}\)Step 2
Find out the number of required events
Total number of events = 52 cards
\(\begin{gathered} A\text{ deck of cards has} \\ 4\text{ Suites - }hearts,\text{ clubs, spade and diamond.} \\ \text{and each suite has} \\ \mleft\lbrace ace,\text{ 2,3,4,5,6,7,8,9, jack, qu}een,\text{ king}\mright\rbrace \end{gathered}\)Therefore, the number of aces = 4
The number of 6 = 4
Step 3
Find the probability of getting an ace or a 6.
\(\begin{gathered} \text{The probability of getting an ace =}\frac{number\text{ of aces in a deck of cards}}{\text{Total number of cards}} \\ \text{The probability of getting an ace}=\frac{4}{52} \\ \text{The probability of g}etting\text{ a 6 =}\frac{number\text{ of 6 in a deck of cards}}{\text{Total number of cards}} \\ \text{The probability of g}etting\text{ a 6}=\frac{4}{52} \end{gathered}\)Therefore,
\(\text{The probability of drawing an ace or a 6 = }\frac{4}{52}+\frac{4}{52}=\frac{8}{52}=\frac{2}{13}\)Hence, Option D
a rectangular picture frame is 5 inches wide; the length of a rectangle is 10 more than its width
Answers
The number of inches by which each dimension must be increased is 10 inches.
Let length and width be increased by x.
so we get, the length = (10 + x) and breadth = (5 + x)
(10 + x)(5 + x) = 6 × 10 × 5
50 + 10 x + 5x + x² = 300
x² + 15x- 250 = 0
x² + 25x- 10x - 250 = 0
x (x + 25) - 10 (x + 25) = 0
(x + 25)(x - 10) = 0
x = -25 is not the right choice as length cannot be negative.
so x = 10
so both dimensions should be increased by 10 inches.

What
is an arithmetic sequence with a common difference of −2?
Answers
Answer:
An arithmetic sequence with a common difference of −2 is 20,18,16,14,12..
Step-by-step explanation:
An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is same. Here, the common difference is -2, which means that each term in the sequence is obtained by subtracting 2 from the previous term.
To find the arithmetic sequence with a common difference of -2, you can start with an first term and then subtract 2 successively to find the subsequent terms.
Let the initial term is 20. Subtracting 2 from 20, we get 18. Subtracting 2 from 18, we get 16. Continuing this pattern, we subtract 2 from each subsequent term to generate the sequence. The arithmetic sequence with a common difference of -2 starting from 20 is
20,18,16,14,12
In this sequence, each term is obtained by subtracting 2 from the previous term, resulting in a common difference of -2.

Problem 3.24 ffective interest rate and PR entire compounain Ans: a. 6.66% Aruna invested Rs 150,000 eighteen months ago. Currently, the investment is worth Rs 168,925. Aruna knows the investment has paid interest every three months, but she does not know what the yield on her investment is. Compute both annual percentage rate (APR) and the effective annual rate of interest on her investment. Ans: 8%; 8.24% arehouse To finance the purchase you have
Answers
Answer:To calculate the annual percentage rate (APR) and effective annual rate of interest on Aruna's investment, we can use the following formula:
APR = (FV/PV)^(1/n) - 1
Where FV is the Future Value, PV is the Present Value, and n is the number of periods.
In this case, FV = 168,925, PV = 150,000, and n = 1.5 (since the investment was held for 18 months).
Therefore, the APR = (168,925/150,000)^(1/1.5) - 1
APR = 6.66%
The effective annual rate of interest (EAR) can be calculated using the following formula:
EAR = (1 + APR/m)^m - 1
Where m is the number of compounding periods in one year.
In this case, m = 4 (since interest is paid every 3 months).
Therefore, the EAR = (1 + 6.66%/4)^4 - 1
EAR = 8.24%

An individual is baking 3 batches of cookies. They used 1.8 oz. of vanilla in one batch of the cookies, 1.25 oz. of vanilla in the second batch and .95 oz. in the third batch. Convert these decimals into fractions, and then put them in ascending order.
Answers
Answer:
19/20 , 1 1/4 , 1 4/5
Step-by-step explanation:
1.8 = 1 4/5 (fraction)
1.8 converts to 18/10. This can be simplified twice, firstly by making it 9/5 since both 18 and 10 are divisible by two, but can be simplified further to 1 4/5
1.25 = 1 1/4 (fraction)
1.25 converts to 125/100. This can be simplified to 5/4 or 1 1/4
0.95 = 19/20 (fraction)
0.95 converts to 95/100. This can be simplified to 19/20
Ascending Order (smallest to largest)
smallest - 19/20
middle - 1 1/4
largest - 1 4/5
I believe this is the right answer, but haven't done fractions in a while so may want to double check to make sure
Suppose f , g , h , and j are functions such that: f ( r ) represents the circumference (in cm) of a circle whose radius is r cm. g ( C ) represents the radius (in cm) of a circle whose circumference is C cm. h ( r ) represents the area (in cm2) of a circle whose radius is r cm. j ( A ) represents the radius (in cm) of a circle whose area is A cm2.
a. Use function notation to represent the area of a circle whose circumference is 133 cm.
b. Use function notation to represent the circumference of a circle whose area is 6.82 cm^2
Answers
Answer:
(a)h(g(133))
(b)f(j(6.82))
Step-by-step explanation:
(a)Area of a circle whose circumference is 133 cm.
Since g(C) represents the radius (in cm) of a circle whose circumference is C cm.
The radius of the circle whose circumference is 133 cm = g(133)h(r) represents the area \((in$ cm^2)\) of a circle whose radius is r cm.
Area, h(r) =h(g(133))Therefore, the area of a circle whose circumference is 133 cm is:
h(g(133))
(b)Circumference of a circle whose area is \(6.82 cm^2\)
j(A) represents the radius (in cm) of a circle whose area is A \(cm^2\).
The radius of the circle of area \(6.82 cm^2\) = j(6.82)f(r) represents the circumference (in cm) of a circle whose radius is r cm.
Therefore:
Circumference, f(r) = f(j(6.82))The circumference of a circle whose area is \(6.82 cm^2\) =f(j(6.82))

How does the graph of f (x) = 3 (4)2-5 + 3 relate to its parent function?
A. The parent function has been 'stretched.
B. The parent function has been translated to the right.
C. The parent function has been translated up.
D. The parent function has been compressed.
Answers
Answer:
The correct answer is D. The graph of f(x) = 3(4)² - 5 + 3 is a transformation of the parent function. The parent function is y = x², which is a simple quadratic function.
In the given equation, the number 4 inside the parentheses represents a horizontal compression or shrink of the graph. The factor of 3 outside the parentheses represents a vertical stretch or expansion. The constant term -5 represents a vertical translation down by 5 units, and the constant term 3 represents a vertical translation up by 3 units.
Therefore, the graph of f(x) = 3(4)² - 5 + 3 is a compressed version of the parent function y = x², shifted down by 5 units and then shifted up by 3 units.
