Let X be a continuous random variable with the pdf given by f(x)= ax2 for 0 < x ≤ 3. Determine the value of constant 'a' correct to 2 decimal places.
The value of the constant a in f(x) = ax² such that 0 < x ≤ 3 is 0.11
How to determine the value of the constant a?The probability density function is given as
f(x) = ax²
Such that
0 < x ≤ 3
To determine the value of the constant a, we make use of the following equation
[tex]\int\limits^a_b {f(x)} \, dx = 1[/tex]
So, we have:
[tex]\int\limits^3_0 {ax^2} \, dx = 1[/tex]
Factor out the constant
[tex]a\int\limits^3_0 {x^2} \, dx = 1[/tex]
Differentiate the equation
So, we have the following representation
[tex]a\frac{x^3}3 |^3_0 = 1[/tex]
Expand the equation
a[3³ - 0³]/3 = 1
Evaluate the difference
a[3³]/3 = 1
Evaluate the quotient
9a = 1
Divide both sides by 9
a = 0.11
Hence, the variable a is 0.11

describe the transformations from the graph f(x)=|x| to the graph d(x) = -|x-3| + 5
The function d(x) = - |x - 3| + 5 is the result of using an horizontal translation, reflection about the x-axis and vertical translation on the function f(x) = |x|.
What kind of transformations are used to transform of the equation of a given graph?
In this question we have the definition of a function (f(x)) and its image (d(x)), the latter is the result of three rigid transformations:
Horizontal translation
f'(x) = f(x - 3)
Reflection about the x-axis
f''(x) = - f'(x)
Vertical translation
d(x) = f''(x) + 5
If we know that f(x) = |x|, then the series of rigid transformations is shown below:
Horizontal translation
f'(x) = |x - 3|
Reflection about the x-axis
f''(x) = - |x - 3|

The result of the given terms is -2/5 as per the given question from complex numbers.
What is a complex number?There is a multiplicative inverse for every nonzero complex number. As a result, complex numbers are a field with real numbers as a subfield. The complex numbers also form a two-dimensional real vector space with 1, I as the standard basis.
Because of this standard basis, the complex numbers form a Cartesian plane known as the complex plane. This allows for a geometric interpretation of complex numbers and operations, as well as the expression of geometric features and constructions in terms of complex numbers. Real numbers, for example, constitute the real line, which corresponds to the complex plane's horizontal axis.
=(((3/5)+(1/5)i)+((4/5)-(2/5)i) -((9/5)-(1/5)i))
=((3/5)+(4/5)-(9/5))-i((1/5)+i((1/5)-(2/5)+(1/5))
=(-2/5)+i(0)
= -2/5

Which is the function on the graph?On the graph we can see some kind of exponential function, such that it has a vertical asymptote at x = -3
It also decreases as x increases, then the exponential function has a base that is smaller than 1 and larger than zero.
Because the y-intercept must be 1, we can discard option D where:
d(0) =4*(0.5)^0 = 4*1 = 4

Bad debt expense is estimated at 3/4 of 1% of sales. a. Determine the amount of the adjusting entry for uncollectible accounts.
If Percent of Sales Method At the end of the current year, Accounts Receivable has a balance of $805,000. the amount of the adjusting entry for uncollectible accounts is $27,150.
How to find the amount of bad debts?a. Amount of bad debts
Amount of bad debts = Sales × Bad debts rate
Amount of bad debts = $3,620,000×0.75%
Amount of bad debts= $27,150
b. Adjusted balances
Accounts Receivable $805,000
Allowance for Doubtful Accounts $20,150
( $27,150- $7,000)
Bad Debt Expense $27,150
c. Net realizable value of accounts receivable
Net realizable value of accounts receivable = Balance of accounts receivables - Allowance for Doubtful Accounts
Net realizable value of accounts receivable = $805,000- $20,150
Net realizable value of accounts receivable = $784,850

Step-by-step explanation:
A standard 52-card deck comprises 4 suits (Spades, Hearts, Diamonds, and Clubs).
Each suit comprises 10 numerical cards (numbered 2 through 10, plus an "ace") and 3 "court" cards (jack, queen and king).
Therefore:
The total number of possible outcomes is 52.There are 4 kings and 4 queens in a standard deck of cards.[tex]\boxed{\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}}[/tex]
[tex]\implies \sf P(Queen)=\dfrac{4}{52}=\dfrac{1}{13}[/tex]
[tex]\implies \sf P(King)=\dfrac{4}{52}=\dfrac{1}{13}[/tex]
Therefore, the probability of drawing a king, replacing the card, and drawing a queen is:
[tex]\implies \sf P(King)\;and\;P(Queen)=\dfrac{1}{13}\times \dfrac{1}{13}=\dfrac{1}{169}[/tex]
Similarly, the probability of drawing a queen, replacing the card, and drawing a king is:
[tex]\implies \sf P(Queen)\;and\;P(King)=\dfrac{1}{13}\times \dfrac{1}{13}=\dfrac{1}{169}[/tex]
Therefore, the probability of drawing a king then a queen, or a queen then a king is:
[tex]\implies \sf P(King\;and\;Queen)\;or\;P(Queen\;and\;King)=\dfrac{1}{169}+\dfrac{1}{169}=\dfrac{2}{169}[/tex]

The first number is 80% of the second number, not 75%, hence, Brad is wrong.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.

Let the first number be 100, then the second number will be:
125% of 100
= (125/100) × 100

Now, divide the first number, 100, by the second number, 125, and then multiply with 100 to know how much % the first number is of the second number:
(100/125) ×100%
