We must use the formula of the z-score to find the the probability that a worker selected at random makes between $400 and $450 dollars. Then let X1 = 400 and X2 = 450 with the mean μ = 400 and standard deviation σ = $50. Then,
z1 = (X1 - μ) / σ = (400-400) / 50 = (0/50) = 0.00 and
z2 = (X2 - μ) / σ = (450 - 400) / 50 = (50/50) = 1.00
Then, the probability yields, P(0.00 ≤ z ≤ 1.00) = 0.3413 - 0.0000 = 0.3413
Answer: 34%
Step-by-step explanation:
The probability that a worker selected at random makes between $400-$450 is 34%

B) y = 3.5 - X
C) y = 5 - X
D) y = 14 - x
Answer:
D
Step-by-step explanation:
I I think that's the method I know if I'm wrong telling me hope it helps.
answer
D, y=14-x
Step-by-step explanation:
b/c x+y/2=7
y=7×2-x
y=7/1 - x/2
y=7×2-x
y=14-x !!!!!!
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.

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

x ∈ [0, 10] or
0 ≤ x ≤ 10

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
