Answer:

$The~answer~you~should~be~getting~is:83x+32y$

Step-by-step explanation:

$First,~combine~the~like~terms~-$

$=43x+-10y+40x+42y\\=(43x+40x)+(-10y+42y)\\=83x+32y$

Answer:

The game is not fair

Step-by-step explanation:

Let us find the sample space. It is the sum of the two spins

1+1 1+2 1+3 1+4

2+1 2+2 2+3 2+4

3+1 3+2 3+3 3+4

4+1 4+2 4+3 4+4

Adding

2,3,4,5

3,4,5,6

4,5,6,7

5,6,7,8

P(2) = 1/16

p(3) = 2/16

p(4) = 3/16

p(5) = 4/16

p(6) = 3/16

p(7) = 2/16

p(8) = 1/16

Player A gets a point if the sum is 6 or more

P (6,7,8) = P (6) + P(7) + P(8) since they are independent event

=( 3+2+1) /16 = 6/16 = 3/8

Player P gets a point if the sum is less than 6

P (2,3,4,5) =P (2) + P(3) + P(4 + P(5)

(1+2+3+4)/16 = 10/16= 5/8

Player B has a better chance of winning, so the game is not fair

An analyst must decide between two different forecasting techniques for weekly sales of roller blades: a linear trend equation a

Amiraneli [1.4K]

Answer:

Following are the responses to the given question:

Step-by-step explanation:

Mean Absolute Deviation MAD

$MAD = \sum_{i=1}^{n} \frac{\left | actual_{i}-forecast_{i} \right |}{n}$

Mean squared error

$MSE=\Sigma^{n}_{i=1} \frac{(Actual_i - Forecast_i)^2}{(n - 1)}$

linear trend equation is $Ft = 124 + 2t$

$MAD = \frac{23}{10} = 2.3\\\\MSE = \frac{91}{9}= 10.11\\\\$

Naive method

$MAD = \frac{36}{9} = 4\\\\MSE = \frac{202}{8}=25.25\\\\MAD (Naive) = 4\\\\MAD (Linear) =2.3\\\\MSE (Naive)=25.25\\\\MSE (Linear)=10.11\\\\$

The area of a rectangle is 4w - 10 square units.

podryga [215]

Area of rectangle = 2(2w - 5) is the factored form of given expression

Multiplying the length and width of a rectangle, we get the area of the rectangle

Solution:

Given that, area of rectangle is 4w - 10 square units

We have to factor the expression

From given,

Area of rectangle = 4w - 10

Take 2 as common factor

Area of rectangle = 2(2w - 5)

Thus the given expression is factored

The area of rectangle is given as:

$Area\ of\ rectangle = length \times width$

$Area\ of\ rectangle = 2 \times (2w - 5)$

Thus, multiplying the length and width of a rectangle, we get the area of the rectangle

When we multiply 2 with 2w - 5 we get the area of rectangle

From above we can say,

Length = 2 or 2w - 5

Width = 2w - 5 or 2

So when dimensions of rectangle are multiplied we get area of rectangle
