The new annual premium including the discount is $504.24.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the new annual premium with the discount, we need to find the total premium and then subtract the discount.

The total premium is the sum of the individual premiums:

Total premium.

= $31.75 + $120.50 + $275.75 + $100.00

= $528.00

The discount is 4.5% of the total premium:

So,

Discount = 0.045 × $528.00 = $23.76

The new annual premium including the discount is:

New premium = Total Premium - Discount

= $528.00 - $23.76

= $504.24

Therefore,

The new annual premium including the discount is $504.24.

Answer:

I got 20 when calculating this

Answer:

they played 20 games together

Step-by-step explanation:

use percentages

Let x be the number of total games.

If 60% is won games then 40% is lost games.

(8/x)*100 = 40

8/x = 4/10

80 = 4x

X = 80/4

Therefore the number of games is 20

The probability that Rachel will pass at least one of the courses is 0.955 or 95.5%

To calculate the probability that Rachel will pass at least one of the courses, we need to use the formula;P(A or B) = P(A) + P(B) - P(A and B)Where P(A or B) is the probability of passing at least one course, P(A) is the probability of passing Math, P(B) is the probability of passing Biology, and P(A and B) is the probability of passing both Math and Biology.

Using the given information, we have:P(A) = 85% = 0.85P(B) = 70% = 0.7P(A and B) = 59.5% = 0.595Substituting these values into the formula, we get:P(passing at least one course) = 0.85 + 0.7 - 0.595= 0.955

As a result, Rachel has a 0.955 or 95.5% chance of passing at least one of the courses.95.5 percent, or 0.955.

a. The unemployment rate is 20%.

b. The labor-force participation rate is 60%.

According to the question,

Working age population- 100,000

Labour force - 60,000

Unemployed - 12000 instructions

a) The unemployment rate is the percentage of the labor force that is unemployed and it is calculated as follows:

Unemployment Rate = \(\frac{Number of unemployed People}{Labor force}\) × 100

When an unemployed population is 12,000 and the labor force is 60,000,

the unemployment rate is  = \(\frac{12000}{60000}\) × 100 = 20%

b) labor force participation rate is the percentage of working adult population that participates in labor either by actively looking for a job, or working. It is calculated as follows:

Labor Force Participation Rate = \(\frac{Labor force}{working age population}\) × 100

When the labor force is 60,000 and the working-age population is 100,000

Labor Force Participation Rate = \(\frac{60000}{100000}\) × 100 = 60%

So, a. The unemployment rate is 20%.

b. The labor-force participation rate is 60 %.

On solving the provided question, we can say that - 45 per hour as for that of 40 hours = \(45x40 = 180 per week\)

An algebraic equation of the form y=mx+b, where m denotes the slope and b the y-intercept, is known as a linear equation. When y and x are variables, the aforementioned is referred to as a "linear equation in two variables." Bivariate linear equations are defined as linear equations with two variables. 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3 are examples of linear equations.

As we work here for  40 hours per a  week, so =   \((8.5-.5 x 5 = 8x5=40 hours a week)\)

45 per hour as for that of 40 hours = \(45x40 = 180 per week\)

Eequation of the tangent line (b) at the given point P.

y + 5¹/² = (1/2) * (-5)⁻¹/² * (x + 5)

To find the slope of the curve at the given point P, we'll first differentiate the function y with respect to x.

Given function: y = x¹/²

Step 1: Differentiate y with respect to x.
dy/dx = (1/2) * x¹/²

Step 2: Plug in the x-coordinate of the point P into the derivative to find the slope at P.
P = (-5, -5¹/²)

dy/dx at P = (1/2) * (-5)⁻¹/²

Slope (a) = (1/2) * (-5)⁻¹/²

Now, we will find the equation of the tangent line at P.

Step 3: Use the point-slope form of a linear equation, y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point P.

y - (-5¹/²) = (1/2) * (-5)⁻¹/²(x - (-5))

Step 4: Simplify the equation.

y + 5¹/² = (1/2) * (-5)⁻¹/² * (x + 5)

This is the equation of the tangent line (b) at the given point P.

There are 9 or 10 distinct ways to arrange 6 beads of distinct colors in a 2x3 grid if reflections and rotations are considered the same. We can solve this problem using Burnside's Lemma.

Burnside's Lemma states that for a group action on a set, the number of fixed points is given by the average over the group of the number of fixed points under a particular group element, where the average is taken over all group elements.

In this case, the group action is the action of rotating and reflecting the grid, and the set is the set of all possible bead arrangements in the grid. To use Burnside's Lemma, we need to find the number of fixed points (i.e., bead arrangements that are unchanged) under each group element, and then take the average over all group elements.

There are a total of $4$ rotations and $2$ reflections possible for a 2x3 grid.

The identity transformation keeps the grid in its original position, and thus there are

6!/(2!3!) = 60

The $90 rotation keeps $3 beads in the same place and switches the other $3, and similarly $180 and $270 rotation also keeps $3 beads in the same place and switches the other $3$, thus there are

3! = 6

The reflection on the horizontal axis keeps $3 beads in the same place and switches the other $3, and similarly the reflection on the vertical axis also keeps $3 beads in the same place and switches the other $3, thus there are

3! = 6

So the average number of fixed points is $(6+6+6+60)/8 = \(\frac{78}{8}\) = 9.75$

So, there are 9 or 10 distinct ways to arrange 6 beads of distinct colors in a 2x3 grid if reflections and rotations are considered the same.
