Answer: 10

Step-by-step explanation:

if x=-5

y= |-5-5| + |-5 + 5|    add what's inside the absolute values first

y=|-10|            absolute value means just take the positive of what's inside, even if its' positive

y=10

Step-by-step explanation:

y = |x-5|+|x+5| when x = -5

y = |(-5)-5|+|(-5)+5|

y = |-10|+|0| note: |x| = positive

y = 10

Mary needs to pay a total of 483.09 pounds per month for her National Insurance contribution at a rate of 12.5% and her pension contribution at a rate of 3.4%.

To calculate Mary's National Insurance contribution, we can use the following formula

National Insurance Contribution = (Salary × Rate) / 12

where Rate is the percentage rate for National Insurance.

Substituting the values given in the problem, we get

National Insurance Contribution = (34833.33 × 12.5%) / 12

= 364.59 pounds per month

To calculate Mary's pension contribution, we can use the following formula

Pension Contribution = (Salary × Rate) / 100

where Rate is the percentage rate for pension contribution.

Substituting the values given in the problem, we get

Pension Contribution = (34833.33 × 3.4%) / 100

= 118.50 pounds per month

Therefore, Mary needs to pay a total of 364.59 + 118.50 = 483.09 pounds per month.

Answer:

a) -3n + 7

b) -5n -2

Step-by-step explanation:

a) 4 1 -2 -5 -8

the difference = -3

the -3 times table = -3, -6, -9, -12 etc

from -3 to 4 we add 7

answer = -3n + 7

check = -3(4) + 7 should give -5 (because -5 is the 4th term in the sequence)

b) -7 -12 -17 -22 -27

the difference = -5

-5 times table = -5, -10, -15, -20

from -5 to -7 we subtract 2

answer = -5n -2

check = -5(5)-2 should give -27 (because -27 is the 5th term in the sequence)

Answer: One angle is 27 degrees and the other is 63 degrees.

Step-by-step explanation:

Use the equation:

x + x + 36 = 90

2x + 36 = 90

     - 36   -36

-------------------------

2x = 54

/2     /2

---------------

x = 27

If x is 27, that is the measure of one angle.

Than 27 + 36 which is 63 is the measure of the other angle because this is 36 more than the previous angle.

Based on the results of the test, either reject or fail to reject the null hypothesis.

Based on the given information, the hypothesis test that can be used to determine whether there has been an increase in the proportion of rooms occupied over the one-year period can be formulated as follows:

Null hypothesis (H0): There is no significant increase in the proportion of rooms occupied over the one-year period.

Alternative hypothesis (Ha): There is a significant increase in the proportion of rooms occupied over the one-year period.

To test this hypothesis, we can use a one-sample proportion test. We can calculate the proportion of rooms occupied in February for each year and then compare the difference in proportions using a confidence interval or a hypothesis test.

If the calculated p-value is less than the level of significance (usually set at 0.05), we can reject the null hypothesis and conclude that there is a significant increase in the proportion of rooms occupied over the one-year period. On the other hand, if the p-value is greater than 0.05, we fail to reject the null hypothesis and conclude that there is no significant increase in the proportion of rooms occupied over the one-year period.

It is important to note that other factors such as content loaded tourism, seasonality, and external events can also impact hotel occupancy data. Therefore, it is essential to consider these factors when analyzing hotel occupancy data and making conclusions about the tourism industry.
Hi! To formulate a hypothesis test to determine if there has been an increase in the proportion of rooms occupied in Florida over a one-year period using the given terms, follow these steps:

1. Define the null hypothesis (H0): There is no significant increase in hotel occupancy between the two consecutive years.

2. Define the alternative hypothesis (H1): There is a significant increase in hotel occupancy between the two consecutive years.

3. Collect hotel occupancy data for February in two consecutive years, specifically focusing on "content loaded tourism," which refers to the experiences and attractions that draw visitors to the area.

4. Analyze the occupancy data and compare the proportions of rooms occupied in both years.

5. Perform a statistical test, such as a Z-test or a Chi-square test, to determine if there is a significant difference between the proportions.

6. Based on the results of the test, either reject or fail to reject the null hypothesis.

If you reject the null hypothesis, it would indicate that there has been a significant increase in hotel occupancy over the one-year period in Florida's tourism industry. If you fail to reject the null hypothesis, it means there is not enough evidence to support a significant increase in occupancy.

The equation of the given parabola is expressed as: y = (-5/4)(x - 4)² + 3

We can see that the given parabola curve comes with x-coordinates and axis of symmetry.

The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y = ax² + bx + c , the axis of symmetry is a vertical line x = −b/2a .

The coordinates of the axis of symmetry are: (4, 3)

Thus:

4 = −b/2a

The equation of a parabola written in vertex form is:

y = a(x - h)² + k

where:

(h, k) is the coordinate of the vertex.

We have that (h, k) = (4, 3)

Thus:

y = a(x - 4)² + 3

At the coordinate (6, -2), we have:

-2 = a(6 - 4)² + 3

-2 = 4a + 3

The weight of Keenan's paperweight is 340 grams using the volume of a pyramid given by V = (1/3)Bh.

To find the weight of Keenan's paperweight, we need to first find its volume. The volume of a pyramid is given by V = (1/3)Bh, where B is the area of the base and h is the height. Substituting the given values, we get:

V = (1/3)(80)(7.5) = 200 cm³

Next, we need to find the mass of the paperweight using the density of the clay. We know that density (p) is defined as mass (m) per unit volume (V), or p = m/V. Rearranging this equation, we get:

m = pV

Substituting the values, we get:

m = (1.7)(200) = 340 grams

The expected value of the distribution is 0.84, which means that on average, a randomly chosen family household in the US in 2016 had 0.84 related children under the age of 18.

To find the expected value of this distribution, we need to multiply each possible number of children by its corresponding probability, and then add up the products. Since the table includes the category "4" to represent "four or more" children, but we're assuming it means exactly four children, we need to adjust the probability for the "4" category.

We can do this by subtracting the total probability of all the other categories from 1, since the probabilities must add up to 1

P(4) = 0.02 - 0.58 - 0.18 - 0.16 - 0.06 = 0.04

Now we can calculate the expected value

E(X) = (0)(0.58) + (1)(0.18) + (2)(0.16) + (3)(0.06) + (4)(0.04)

= 0 + 0.18 + 0.32 + 0.18 + 0.16

To find the length of the loop of the given curve, we need to use the formula for arc length: L = ∫√(dx/dt)² + (dy/dt)² dt.

where dx/dt and dy/dt are the derivatives of x and y with respect to t.
In this case, we have:

dx/dt = 12 - 12t²
dy/dt = 24t

Therefore,
(dx/dt)² + (dy/dt)² = (12 - 12t²)² + (24t)² = 144t⁴ - 96t² + 144
and √(dx/dt)² + (dy/dt)² = √(144t⁴ - 96t² + 144)
The loop of the curve occurs when y = 0, which implies 12t² = 0, i.e., t = 0.

So, we need to integrate from t = 0 to t = 2: L = ∫₀² √(144t⁴ - 96t² + 144) dt
This integral can be quite difficult to solve analytically, so we can use numerical methods to approximate the value of L. Using a numerical integration tool, we get: L ≈ 33.14

Therefore, the length of the loop of the given curve is approximately 33.14 units.

Answer:

Step-by-step explanation:

Step-by-step explanation:

Starting with x^2 + 6x = 9:

1. Move the constant term to the right side: x^2 + 6x - 9 = 0

2. Find the coefficient of x (which is 6) and divide it by 2: 6/2 = 3

3. Square the result from step 2: 3^2 = 9

4. Add the result from step 3 to both sides of the equation to complete the square: x^2 + 6x + 9 = 18

5. Factor the left side of the equation: (x + 3)^2 = 18

6. Take the square root of both sides of the equation: x + 3 = ±√18

7. Simplify the right side of the equation: x + 3 = ±3√2

8. Solve for x by subtracting 3 from both sides of the equation: x = -3 ±3√2

So the solutions are x = -3 + 3√2 and x = -3 - 3√2.

Solving we get that option (C) that is x equals plus or minus root 18 minus 3 is correct.

Completing the Square is a method used to solve a quadratic equation by changing the form of the equation so that the left side is a perfect square.

The steps of the method are as follows:

Isolate the number or variable c to the right side of the equation. Divide all terms by a (the coefficient of x2, unless x2 has no coefficient). Divide coefficient b by two and then square it. Add this value to both sides of the equation.

By dividing the state's total personal income of 268025 million dollars by its population of 5.5935 million, one can estimate the per capita income in 2022 to be around 47,917 dollars per person.

Finding the values of P and t for 2022 is necessary before we can determine the per capita income.

Assuming that t is the number of years since the year 2000, t will equal 22 in 2022.

The state's population in millions in 2022 can be determined using the P equation:

The P equation can be used to calculate the state's population in millions for the year 2022:

P = 0.034 (52) plus 4.909 to equal 5.5935 million

Using the computation for the total amount of personal income earned in the state, we can compute the total personal income in millions of dollars in 2022:

I is equal to 6983(22) + 109359, or 268025 trillion dollars.

To calculate the per capita income, we divide the total personal income by the population:

Total personal income divided by population yields a per-person income of 47,917 dollars (26,8025 / 5.5935).

Consequently, the amount of per capita income predicted for 2022 is almost 47,917 dollars per person.
