The number of ways can 6 couches and 5 beds are chosen from a shipment of 11 couches and 12 beds will be 55440

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

It is given that, the total number of couches and beds will be 11 and 10.

We have to find a number of ways for the 5 couches and 7 beds are chosen from a shipment.

The different methods are there to select 5 couches and 7 beds from a shipment of 11 couches and 10 beds obtained as,

=11C₅× 10C₇

=462×120

=55440

Thus, the number of ways can 6 couches and 5 beds are chosen from a shipment of 11 couches and 12 beds will be 55440

Answer:

Option: A is the correct answer.

Step-by-step explanation:

Clearly from the graph we could observe that the graph is a decay exponential function as the graph of the function is decreasing with the increasing value of x.

Hence, the rate has to be less than 1.

So, option: B and D are ruled out as they represent a growth exponential function.

Also from the graph given in the question we could observe that when x=0 the value of y is:

y=4

So, the exponential function that is represented by the graph is:

Answer: true

Step-by-step explanation:

The coordinates of the points are given as follows:

The coordinates of the fourth vertex are of:

Answer:

10.5 cm

Step-by-step explanation:

YZ corresponds to TU

YZ:TU = 9:3 = 3:1

XY corresponds to ST

ST = 3.5 cm

XY:ST = 3:1

XY/ST = 3/1

XY/3.5 cm = 3

XY = 10.5 cm

The value of the car zero km is given by the expression x = 60000.

LET ME EXPLAIN SOMETHING:

An algebraic expression is one that has several operations between numbers and letters (unknowns): addition, multiplication, subtraction, division, potentiation, rooting, etc.

LET'S GO TO THE SOLUTION:

Let x be the initial value of the car, we know that it depreciates 10% when leaving the agency and another 5% after one year. If the value of this car is $51,300.00 after 1 year, we will have to:

When you leave the agency, your value decreases by 10%:

After a year, its value decreases by 5%:

0.855x = 51300

x = 60000

Answer:

f⁻¹(x)= 9x + 18

Step-by-step explanation:

1. Replace f(x) with x, and x with y:  x=1/9y-2

2. Solve for y:

   x=1/9y-2

   9x=y-18

   9x+18=y

3. Replace y in step 2 with f⁻¹(x)

Answer:

d) 189.3 in²

Step-by-step explanation:

Area of rectangle is,

→ w × l

→ 10 × 15

→ 150 in²

Area of semi circle is,

→ (1/2)πr²

→ (1/2) × 3.14 × (5)²

→ 1.57 × 25

→ 39.3 in²

Now the total area will be,

→ 150 + 39

→ 189.3 in²

Thus, total area is 189.3 in².

Answer:

8

Step-by-step explanation:

Because we multiply 4 by both sides

2 times 4 is 8 for girls

4 times 3 is 12 for boys

So it asked for girls and 4 times 2 is 8

So the answer is 8

8 women are in the class.

Answer:

64

Step-by-step explanation:

Since one of the 3 identical factors is 4, then the number is 4×4×4, or 4³

The percent error of her estimate relative to the time it actually took is approximately 5.9%

Error = Estimated time to construct the shed - Actual time taken to build the shed

= 18 hours - 17 hours

= 1 hour

Percent error = error / actual time × 100

= 1/17 × 100

= 0.058823529411764 × 100

= 5.882352941176470

Approximately,

5.9%

Consequently, the percent error of Keiko estimation and actual time is 5.9%

Applying the properties of a parallelogram:

1. Length of AC = 24.8 units

2. x = 1

Some properties of parallelogram we need to recall in  order to solve the problem given are:

1. q = 1x + 10

AC = 7x + 8

Therefore:

q = 1/2(AC) [based on the property of a parallelogram]

Substitute

x + 10 = 1/2(7x + 8)

Solve for x

2(x + 10) = 7x + 8

2x + 20 = 7x + 8

2x - 7x = -20 + 8

-5x = -12

x = -12/-5

x = 2.4

Length of AC = 7x + 8 = 7(2.4) + 8

Length of AC = 24.8 units

2. x + 8 = 7x + 2 [based on the property of a parallelogram]

x - 7x = -8 + 2

-6x = -6

-6x/-6 = -6/-6

x = 1

The required leaves values for the given stems are calculated below.

A plot where every information esteem is parted into a "leaf" (typically the last digit) and a "stem" (different digits). For instance "32" is parted into "3" (stem) and "2" (leaf). The "stem" values are recorded down, and the "leaf" values are recorded close to them.

For example , 42, 34, 48, and so on.

Here 42 and 48 qualities will be written in stem 4 as their most memorable digit is 4, while 2 and 8 will be placed in the leaf side.

From the solution to the given inequality, the correction representations are -6x + 15 < 10 - 5x and a number line from -3 to 7, with an open circle at 5 and an arrow pointing to the right.

From the question, we are to determine the correct representations of the given inequality

The given inequality is

-3(2x - 5) < 5(2 - x)

To determine the correct representation, we will solve the inequality

Solving the inequality

-3(2x - 5) < 5(2 - x)

Clear the parentheses by applying the distributive property

-6x + 15 < 10 - 5x

Add 6x to both sides

-6x + 6x + 15 < 10 - 5x + 6x

15 < 10 + x

Subtract 10 from both sides

15 - 10 < 10 - 10 + x

5 < x

Therefore,

x > 5

Hence, the correction representations are -6x + 15 < 10 - 5x and the number for x > 5
