Caroline's gross earnings are $1, 126 for the current pay period. Find the state disability insurance (SDI) amount deducted from
her paycheck based on a rate of 1%of her gross earnings. Caroline has not earned $31, 800 this year.
$11.26
$13.98
$10.59
$12.52
Answer:
A) 11.26
Step-by-step explanation:
To find the state disability insurance (SDI) amount deducted from Caroline's paycheck, we need to calculate 1% of her gross earnings.
1% of $1,126 is (1/100) x $1,126 = $11.26
So, the SDI amount deducted from Caroline's paycheck would be $11.26.

find X and AC
Answer:
#7: x = 7
#8: AC = 52
Step-by-step explanation:
We know that part + part = whole.
Thus, AB + BC = AC
Using this fact, we can solve for x:
[tex]6x-3+2x-1=10x-18\\8x-4=10x-18\\8x=10x-14\\-2x=-14\\x=7[/tex]
We can simply plug in x in 10x-18 to find the length of AC:
[tex]10(7)-18=AC\\70-18=AC\\52=AC[/tex]
You can also check that AB + BC = AC by plugging in x for 6x -3 and 2x -1 and finding the sum of the two parts of the line:
[tex]6(7)-3+2(7)-1=52\\42-3+14-1=52\\39+13=52\\52=52[/tex]

12sec²x-16=0
Solve for the following equation by the quadratic formula or factoring
Answer:
Step-by-step explanation:
The equation 12sec²x - 16 = 0 is not a polynomial equation and cannot be factored into the product of two or more polynomials.
To solve for x, we need to isolate sec²x by adding 16 to both sides and then dividing by 12:
12sec²x - 16 + 16 = 0 + 16
12sec²x = 16
sec²x = 16 / 12
sec²x = 4/3
Now that we have isolated sec²x, we can find x by finding the inverse secant of 4/3.
Note that the inverse secant is a multi-valued function, so there may be multiple solutions for x, which can be obtained using a calculator or tables of trigonometric functions.
the minimum of two independent exponential random variables is also exponential. true or false? why?
False. The minimum of two independent exponential random variables is not necessarily exponential.
For two independent exponential random variables X and Y, with rate parameters λ1 and λ2 respectively, the minimum of X and Y is a random variable Z with the cumulative distribution function (CDF) given by
[tex]F_Z(z) = 1 - e^(-(λ1+λ2)z)[/tex].
The survival function of Z is given by
[tex]S_Z(z) = e^(-(λ1+λ2)z)[/tex].
Therefore, the probability density function of Z is
[tex]f_Z(z) = (λ1 + λ2)e^(-(λ1+λ2)z)[/tex].
This is not an exponential distribution because the form of the probability density function is not of the form [tex]f(z) = λe^(-λz)[/tex].

If Arnav applies the Distributive Property to the expression 4 + 8(y + 3) + x, the expression that he will get is 4 + 8y + 24 + x or 8y + x + 28
As per the data given:
Arnav applies the Distributive Property to the expression 4 + 8(y + 3) + x.
Here we have to determine the equivalent expression after applying the Distributive Property to the expression 4 + 8(y + 3) + x.
Distributive property states that, for real numbers a, b, and c:
a (b + c) = ab + ac
An expression of the form A(B + C) can be solved as A × (B + C) = AB + AC.
From the given expression the part which we have to apply distributive property is 8(y + 3)
Here a = 8
b = y
c = 3
So, applying property in the expression
= 4 + 8(y + 3) + x
= 4 + 8y + 24 + x
= 8y + x + 28
Therefore, the equivalent expression is 4 + 8y + 24 + x or 8y + x + 28

can you Identify the initial amount a and the growth factor b in the exponential function g(x) = 14 × 2x ?
The initial amount, a, in the exponential function g(x) = 14 × 2x is 14, and the growth factor, b, is 2.
This can be determined by looking at the equation and noting that the coefficient of x is 2, which indicates that the base of the exponential is 2. We can also calculate the initial amount and growth factor mathematically.
To calculate the initial amount, a, we can take the equation g(x) = 14 × 2x and set x = 0, yielding g(0) = 14 × 20, which simplifies to 14. To calculate the growth factor, b, we can take the natural log of both sides of the equation to yield ln(g(x)) = ln(14 × 2x).
Simplifying this gives
ln(g(x)) = ln(14) + ln(2x).
We can then divide both sides by x to yield
ln(g(x))/x = ln(14) + ln(2)/x.
We can then take the limit as x approaches 0, which yields
ln(g(0))/0 = ln(14) + ln(2)/0.
This simplifies to
ln(g(0)) = ln(14) + ln(2), which can be rearranged to
ln(2) = ln(g(0)) - ln(14).
Taking the exponential of both sides gives us
2 = e^(ln(g(0)) - ln(14)), which simplifies to
2 = g(0)/14, or b = g(0)/14 = 2.
This shows that the initial amount, a, is 14, and the growth factor, b, is 2.

The length of a rectangular poster is 4 more inches than three times its width. The
area of the poster is 340 square inches. Solve for the dimensions (length and width)
of the poster.
The dimensions are Width = 10 inches and Length = 13 inches
Draw a rectangle. If the length is 4 inches longer than three times its width, we can write the width as "w" and the length as the 3*width + 4
Area is (width)(Length) = (width)(3*width+4)
W
----------
| |
| |
| | L = 3w+4
| |
| |
-----------
A = (3w+4)(w)
A = 3w² + 4w = 340.
(Problem states that area is 340 sq in)
Need to solve this quadratic equation
3y² + 4y - 340 = 0
Factor:
(w - 10) (w + 13) = 0
So
w - 10 = 0. or. w + 13 = 0
Solve these and get
w = 10. or. w = -13

Suppose that f(x)= x^2 and g(x)= 4/5x^2.Which statement best compares the graph of g(x) with the graph of f(x).
The graph of G(x) is the graph of F(x) compressed vertically.
Why is the expression?The equation of the graph of F(x) is given by x^2 and that of G(x) is given by 4/5 x^2.
The coefficient of x^2 in the equation of G(x) is 4/5, which is smaller than the coefficient of x^2 in the equation of F(x), which is 1.
This means that for a given value of x, the value of G(x) will always be less than the value of F(x). In other words, the graph of G(x) will be closer to the x-axis compared to the graph of F(x), which is equivalent to compressing the graph of F(x) vertically.
Therefore, the statement that best compares the graph of G(x) with the graph of F(x) is "The graph of G(x) is the graph of F(x) compressed vertically".

If 6 times the 6th term of an A.P., is equal to 9 times the 9th term, find its 15th term
If 6 times the 6th term of an A.P is equal to 9 times the 9th term, then 15th term of the A.P. is -2d with d as the common difference.
Let's call the common difference of the arithmetic progression (A.P.) "d". The nth term of an A.P. is given by the formula T = a + (n - 1)d, where a is the first term and n is the term number.
Using this formula, we can write two expressions for the 6th and 9th terms:
T₆ = a + (6 - 1)d = a + 5d
T₉ = a + (9 - 1)d = a + 8d
According to the problem, 6 times the 6th term of the A.P. is equal to 9 times the 9th term, so we can write the following equation:
6T₆ = 9T₉
Substituting the expressions for T₆ and T₉, we get:
6(a + 5d) = 9(a + 8d)
Expanding and solving for a, we get:
6a + 30d = 9a + 72d
Subtracting 6a from both sides:
24d = 3a + 72d
Subtracting 72d from both sides:
-48d = 3a
Dividing both sides by 3:
-16d = a
So, the first term of the A.P. is -16d.
To find the 15th term, we can use the formula for the nth term:
T₁₅ = a + (15 - 1)d = -16d + 14d = -2d
So, the 15th term of the A.P. is -2d.
