Answer:
(d) is true
Explanation:
Given
[tex]Brown = 8[/tex]
[tex]Purple = 7[/tex]
Required
Which of the options is true
A) P(Brown) = P(Not Brown)
P(Brown) is calculated as:
[tex]P(Brown)=\frac{Brown}{Brown + Purple}[/tex]
[tex]P(Brown)=\frac{8}{8+7}[/tex]
[tex]P(Brown)=\frac{8}{15}[/tex]
P(Not Brown) is calculated as:
[tex]P(Not\ Brown) = 1 - P(Brown)[/tex] --- Complement rule
[tex]P(Not\ Brown) = 1 - \frac{8}{15}[/tex]
Solve
[tex]P(Not\ Brown) = \frac{7}{15}[/tex]
Both are not equal.
Hence, (a) is not true
(b) P(Brown) < P(Not Brown)
In (a) above
[tex]P(Brown)=\frac{8}{15}[/tex]
[tex]P(Not\ Brown) = \frac{7}{15}[/tex]
By comparison;
[tex]P(Brown) > P(Not\ Brown)[/tex]
Because:
[tex]8/15 > 7/15[/tex]
Hence, (b) is not true
(c) P(Not Brown) > P(Brown)
This is the same as (b)
i.e. both conditions represent the same.
Hence, (c) is incorrect
(d) P(Brown) > P(Not Brown)
In (b), we established that
[tex]P(Brown) > P(Not\ Brown)[/tex]
Because:
[tex]P(Brown)=\frac{8}{15}[/tex]
[tex]P(Not\ Brown) = \frac{7}{15}[/tex]
[tex]8/15 > 7/15[/tex]
Hence, (d) is true

You have recently been employed in a medium size company and deployed in the accounts department.
Your head of section has given you the following extract from the cashbook for the month of February 2021:
Sh. Sh.
Receipts during the month 2,938,000 Balance brought forward (1.2.2021) 1,522,000
Balance carried forward (28.2.2021) 1,108,000 Payments during the month 2,524,000
4,046,000 4,046,000
The head of section further informs you that all receipts are banked intact and all payments are made by cheque. On investigation, you discover the following:
1. Bank charges and commissions amounting to Sh. 272,000 entered on the bank statement had not been entered in the cashbook.
2. Cheques drawn amounting to Sh. 534,000 had not been presented to the bank for payment.
3. Cheques received totaling Sh. 1,524,000 had been entered in the cashbook and paid into the bank, but had not been credited by the bank until March 2021.
4. A cheque for Sh. 44,000 had been entered as a receipt in the cashbook instead of a payment.
5. A cheque for Sh. 50,000 had been debited by the bank by mistake.
6. A cheque received for Sh. 160,000 had been returned unpaid. No adjustment had been made in the cashbook.
7. All dividends receivable are credited direct to the bank account. During the month of February 2021. Dividends totaling Sh. 124,000 were credited by the bank and no entries had been made in the cashbook.
8. A cheque drawn for Sh. 12,000 had been incorrectly entered in the cash book as Sh. 132,000.
9. The balance brought forward should have been Sh. 1,422,000.
10. The bank statement as at 28 February 2021 showed on overdraft of Sh. 2,324,000.
Required:
(i) The adjusted cashbook as at 28 February 2021 (4 marks)
(ii) Bank reconciliation statement as at 28 February 2021. (6 marks)

Step-by-step explanation:
The function y=e−3x is vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units, find the resulting function.
y=1/4e^3x-5
After a whole year this hasn't been answered
The resulting function of y=e^(−3x), when vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units is y=[4e^(−3x)] + 5.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)Vertical shift
Up by d units: Down by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: [tex]y = k \times f(x)[/tex]Horizontal stretch by a factor k: [tex]y = f(\dfrac{x}{k})[/tex]Given the function [tex]y=e^{-3x}[/tex] is vertically stretched by a factor of 4. Therefore, the function will be written as,
[tex]y = 4 \times e^{-3x}[/tex]
Now, the function is shifted up by 5 units, therefore, the function will become,
[tex]y = (4e^{-3x})+5[/tex]
Hence, the resulting function of y=e^(−3x) , when vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units is y=[4e^(−3x)] + 5.

Circle the expression that has the smallest value when x = 4
5 – x 1/2 x x + 1 x - 4
9514 1404 393
Answer:
(d) x-4
Step-by-step explanation:
If we assume your answer choices are ...
(a) 5 -x = 5 -4 = 1
(b) 1/2x = 1/2(4) = 2
(c) x +1 = 4 +1 = 5
(d) x -4 = 4 -4 = 0
Then the last choice (d) x -4 has the smallest value at x=4.

Answer:
x≥0
Step-by-step explanation:
the domain is anything above 0
The domain of the graph is [0, 10] or 0 ≤ x ≤ 10 when the annual growth of the python population from the beginning of 2000 to 2010.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
Florida Fish and Wildlife is having problems with the growing population of Pythons in the Everglades.
As we can see in the graph the annual growth of the python population from the beginning of 2000 to 2010 is continuously increasing between 0 to 10,
Mathematically,
x ∈ [0, 10] or
0 ≤ x ≤ 10
Thus, the domain of the graph is [0, 10] or 0 ≤ x ≤ 10 when the annual growth of the python population from the beginning of 2000 to 2010.

View the work below from a student last year. What was their mistake? Be detailed in their response.
-3(x + 4) = 2x - 5
-3x + 4 = 2x - 5
4 = 5x - 5
9 = 5x
1.8 = x
Answer:
x = -1.4
Step-by-step explanation:
-3(x + 4) = 2x - 5
-3x + (-3*4) = 2x - 5
The mistake was in the above equation where -3 should be multiplied with 4.
-3x -12 = 2x -5
5 -12 = 2x+3x
-7 = 5x

Answer:
A = 1, B = 1
Step-by-step explanation:
From the question
(2x+1)/(x²+x) = A/x + B/(x+1)
(2x+1)/(x²+x) = [A(x+1)+(Bx)]/(x²+x)
Equation the numerator
2x+1 ≡ A(x+1) +Bx
2x+1 ≡ Ax+A+Bx
From the above,
A = 1.
And,
2x = Ax+Bx................ Equation 1
A+B = 2
Substitute the value of A into Equation 1
1+B = 2
B = 2-1
B = 1
