Answer:

income tax=13% of total salary

Step-by-step explanation:

Here,

let salary be 'x'

Now,

13%of x = $10 000

13/100 × x = $10 000

13x = 1000000

x=10 00000/13

Therefore x =76,923.0769

His salary that year was 76,923.0769

Step-by-step explanation:

The required value of the x in the expression of angle is 19.

An expression of angle is given as 7x + 2 = 135°, the value of the x is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
7x + 2 = 135
Simplifying,
7x = 135 - 2
7x = 133
x = 133 / 7
x = 19

Thus, the required value of the x in the expression of angle is 19.

Answer:  480 and 253.2

Step-by-step explanation:

For the first one we want to do (12 x 5 / 2) x 16 which equals 480.

For the next question, the answer is 253.2 because 2πrh is the formula of lateral area. If we just plug in the numbers it's (2 x 3.14 x 4.8 x 8.4) = 253.2cm

[tex]~~~~~~150\times x\% = 35\\\\\implies 150 \times \dfrac{x}{100} = 35\\\\\implies \dfrac{3x}{2}=35\\\\\implies 3x = 35\cdot 2\\\\\implies 3x = 70\\\\\implies x = \dfrac{70}{3}\\\\\implies x =23.\overline{3}\\\\\text{So, 35 is}~ 23.\overline{3}\%~ \text{of} ~150.[/tex]

Quadratic equation has a leading degrees of 2. The correct equation in vertex form is (x - 3)^2 + 5

Quadratic equation has a leading degrees of 2.

Given the quadratic function expressed as:

f(x) = x^2 - 6x + 14

Complete the square

x^2 - 6x + (-3)^2 - (-3)^2 + 14

(x- 3)^2 - 9 + 14
(x - 3)^2 + 5

Hence the correct equation in vertex form is (x - 3)^2 + 5

For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.

A combination is a mathematical technique that determines the number of possible arrangements.

Let's we have to define

A, B, and C, as the regions in the spinner.

So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:

The outcome of spin 1, the outcome of spin 2, outcome of spin 3.

The total number of  different outcomes will be:

Answer:

26.17%

Step-by-step explanation:

P(Grey) = 1/4

P(Grey at least 2 times in 4) = 1 - P(no Grey in 4) - P(1 Grey in 4)

P(no Grey in 4) = 4C0 * 3/4 * 3/4 * 3/4 * 3/4 = 81/256

P(1 Grey in 4) = 4C1 * 1/4 * 3/4 * 3/4 * 3/4 = 27/64

P(Grey at least 2 times in 4) = 1 -  81/256 -  27/64 = (256-81-108)/256=67/256=26.17%

The standard deviation of the population dataset is 9.35

The dataset is given as:

18, 14, 35, 34, 11, 26

Start by calculating the mean using:

Mean = Sum/Count

This gives:

[tex]\bar x = (18+ 14+ 35+ 34+ 11+ 26)/6[/tex]

Evaluate

[tex]\bar x = 23[/tex]

The standard deviation is then calculated using:

[tex]\sigma = \sqrt{\frac{\sum (x - \bar x)^2}{n}}[/tex]

This gives

[tex]\sigma = \sqrt{\frac{(18 - 23)^2 + (14- 23)^2 + (35- 23)^2 + (34- 23)^2 + (11- 23)^2 + (26- 23)^2}{6}}[/tex]

Evaluate

[tex]\sigma = \sqrt{\frac{524}{6}}[/tex]

This gives

[tex]\sigma = 9.35[/tex]

Answer:

(6, 0)

Step-by-step explanation:

Coordinates are written in the form (x, y), where x is the x-axis value that the point is in, in this case 6, and where y is the y-axis value, in this case 0.

Hi!

Answer:

(6, 0)

Step-by-step explanation:

Coordinate point "G" on this graph is on the very bottom. On the X axis, point G is on the 6. On the Y axis, its on the 0, so since the domain, (X) comes first before the range, (Y), you get (6, 0)

Answer:

y = 15

Step-by-step explanation:

JKLM ~ PQRS means that quadrilateral JKLM is similar to quadrilateral PQRS.

In similar shapes the corresponding sides have same ratio and the corresponding angles are congruent.

This means angle J is congruent to angle P, K is congruent to Q, L is congruent to R and M is congruent to S. Order of the vertices matters.

Solving for y.

Angle J is congruent to angle P.

5y - 4 = 71 Add 4 on both sides.

5y = 71 + 4

5y = 75  Divide both sides with 5.

y = 15

Answer:

a) 11/100

b) 60 times

Step-by-step explanation:

a)

We want to find the probability that a 3 will be rolled.

Probability = # of favorable outcomes / total # of outcomes.

Here the number of favorable outcomes will be the number of times a 3 was rolled and the total number of outcomes will simply be the # of times that the dice was rolled which can be calculated by finding the sum of the frequencies of each number.

So # of favorable outcomes = 11 ( as the dice was rolled on a 3 11 times.)

And the total number of outcomes would be 100 ( the sum of the frequencies , 12 + 35 + 11 + 23 + 7 + 12 = 100 )

So the probability of rolling a 3 would be 11/100

b)

For this part we want to find the expected times that a 6 would be rolled if we rolled the die 500 more times.

To calculate this we simply find the probability of rolling a 6 and then multiply that by 500.

So again probability = # of favorable outcomes / total # of outcomes.

Here # of favorable outcomes is frequency of rolling a 6 which would be 12 and the total number of outcomes is 100 as we found out during the last part.

So the probability of rolling a 6 is 12/100 or 3/25

We then multiply this by 500 to find the expected number of times a 6 would be rolled if the dice was rolled 500 more times

So our answer = 3/25 × 500 = 60 times
