The value of x corresponding to a z-score of -2.25 is 5.75.

What is z-score ?

A z-score is a standardized score that expresses the distance of a data point from the mean in terms of the number of standard deviations. It indicates how many standard deviations a data point is above or below the mean of the distribution.

Given that x follows a normal distribution with mean μ = 8 and standard deviation σ = 1, we can find the z-score corresponding to a given value of x using the formula:

z = (x - μ) / σ

To find the value of x corresponding to a z-score of -2.25, we can rearrange the above formula as follows:

x = μ + z * σ

= 8 + (-2.25) * 1

= 8 - 2.25

= 5.75

Therefore, the value of x corresponding to a z-score of -2.25 is 5.75.

The  graph of g(x) = f(x - 1) - 5 is: C: The graph of g(x) is shifted 1 unit right and 5 units down.

Some of the terminologies in shifting of functions are:

1. Shift graph functions y = f(x) to the left: This means that we will be adding inside the function.

y= f(x + b)  , where b is constant

2. Shift graph function y = f(x) to the right means that we will be subtracting inside the function

y =  f(x - b)

3. To shift graph function y = f(x) up by b units means that we would be adding outside the function:

y = f(x) + b

4. To shift graph down by b units means that we would be subtracting outside the function:

y = f(x) - b

Therefore, by the definition we can say that the graph of g(x) = f(x-1)-5 is the graph of f(x) 1 units to the right and 5 units down.

Taxable income = $81,120,Total tax owed = $4,732.50 + $414.40 = $5,146.90 per year,Annual net pay = $81,120 - $5,146.90 = $75,973.10,Fortnightly net pay = $75,973.10 / 26 = $2,922.81

An amount of money that a government asks people to pay based on their income, property value, etc., and  is used to pay for things that the government does.

The accountant's gross income for two weeks is $3,120, so his gross income for the year is:

3120 x 26 = $81,120

Since they are not allowed to deduct tax, their taxable income equals their gross income:

Taxable income = $81,120

ii. Using the presented tax table, we can determine the accountant's tax liability:

Taxable income = $81,120

Income tax over $80,000 = (81,120 - $80,000) x 0.37 = $414.40

Income tax over $37,000 = ($37,000 - $18,200) x 0.325 = $4,732.50

Total tax liability = $4,732.50 + 414.40 = $5,146.90 per year

iii. An accountant's annual net salary is his gross income minus  tax liability:

Annual net salary = $81,120 - $5,146.90 = $75,973.10

iv. The accountant's semi-monthly net salary is the annual net salary divided by 26:

Net salary for two weeks = $75,973.10 / 26 = $2,922.81

The required value of x that makes the equation 2(x - 5) = 12 true when x is chosen from the set {10, 11, 12, 13} is x = 11.

To make the equation 2(x - 5) = 12 true, we need to solve for x. We can start by simplifying the equation using the distributive property:

2(x - 5) = 12

2x - 10 = 12

Next, we can isolate the variable x by adding 10 to both sides:

2x - 10 + 10 = 12 + 10

2x = 22

Finally, we can solve for x by dividing both sides by 2:

2x/2 = 22/2

x = 11

Therefore, the value of x that makes the equation 2(x - 5) = 12 true when x is chosen from the set {10, 11, 12, 13} is x = 11.

[tex]10x = 360[/tex]

[tex]x = 36[/tex]

So x, the smallest angle in this quadrilateral, is 36°.

Answer:

32 yards = 96 feet (1 yard = 3 feet, so 32 yards x 3 feet/yard = 96 feet)

1 foot = 12 inches, so 4 feet = 48 inches

3 miles = 5,280 yards (1 mile = 1,760 yards, so 3 miles x 1,760 yards/mile = 5,280 yards)

Therefore, the conversions are:

Answer:

x = 9.75 and y = 0

Step-by-step explanation:

Since the path of the windsurfer crosses both angles, we can use the fact that the sum of the angles around a point is 180 degrees to set up an equation:

m∠1 + m∠2 + m∠3 = 180°

We know that m∠1 = (8x + 5y)° and m∠2 = (8x + y)°. We can also see from the diagram that m∠3 = 180° - 78° = 102°. Substituting these values into the equation, we get:

(8x + 5y)° + (8x + y)° + 102° = 180°

Simplifying and solving for x and y, we get:

16x + 6y = 78°

8x = 78° - 6y

x = (78° - 6y)/8

We can substitute this expression for x into one of the earlier equations to solve for y:

8[(78° - 6y)/8] + y = 78°

78° - 6y + y = 78°

-5y = 0

y = 0

Now that we know y = 0, we can substitute this value into the equation we found for x:

x = (78° - 6(0))/8 = 9.75

Step-by-step explanation:

If x and y vary inversely, we can write the equation:

xy = k

where k is a constant of proportionality. To solve for k, we can use the values x = -3 and y = 4:

(-3)(4) = k

-12 = k

So the equation relating x and y is:

xy = -12

To find y when x = 6, we can plug in these values and solve for y:

(6)y = -12

y = -2

So when x = 6, y = -2.

Answer: [tex]\tt{a.\fra{2}{3}}[/tex]

Step-by-step explanation:

If cos A = sqrt(5)/3 and tan A < 0, we can use the fact that:

sin^2 A + cos^2 A = 1

to find the value of sin A. First, we can square both sides of the equation cos A = sqrt(5)/3 to get:

cos^2 A = 5/9

Then, we can use the identity sin^2 A = 1 - cos^2 A to get:

sin^2 A = 1 - cos^2 A

sin^2 A = 1 - 5/9

sin^2 A = 4/9

Taking the square root of both sides gives us:

sin A = +/- 2/3

However, we know that tan A < 0, which means that the sine and cosine functions have opposite signs in the quadrant where angle A lies. Since cosine is positive (given by cos A = sqrt(5)/3), angle A must lie in either the first or fourth quadrant, where sine is positive or negative, respectively. Therefore, we can eliminate the negative solution and conclude that:

sin A = 2/3

Answer:

The area is 92 square yards.

Step-by-step explanation:

We can decompose this figure into a rectangle and a triangle.

First, we can find the area of the rectangle.

A(rect) = length × width

A(rect) = 10 × 8

A(rect) = 80 yd²

Next, we can find the area of the triangle.

A(triangle) = (1/2) × base × height

[tex]A(\text{triangle}) = \dfrac{1}{2} \, (13 - 10) \times 8[/tex]

[tex]A(\text{triangle}) = \dfrac{3}{2} \times 8[/tex]

[tex]A(\text{triangle}) = 12 \text{ yd}^2[/tex]

Finally, we can add the two shapes' areas to get the area of the entire figure.

A = A(rect) + A(triangle)

A = 80 yd² + 12 yd²

A = 92 yd²

Answer: 92 yd²

Step-by-step explanation:

Decomposition means to break the shape into parts, but it's not necessary to break apart.

This is a trapezoid turned sideways A=1/2(b1+b1)h

b1=10

b2=13

h=8

A=1/2(10+13)8 =92 yd²

if you decompose, you can make the top a triangle and bottom a rectangle.

A(triangle) = 1/2(b)(h)     b=3   h=8

                 1/2(b)(h)

                 = 12

A(rectangle)=bh     b=10     h=8

                  =10*8

                   =80

Add the 2 and you get 92 again

If Lerato spends ²/₅ of her money, loses ¹/₃ of what is left, and still has R6 left, the amount of money she had to begin with was R15.
