-8+20 will have a positive sum because the positive number 20 is greater than the negative number 8

Answer:

Positive

Step-by-step explanation:

Without adding you can tell wether a number is positive or negative with addition because it is basically a number line. Think of subtracting -8 from 0 which would give you -8. Now add 20 to it causing it to get out of the negatives and become positive.

-As the size of the sample increases, the mean of the distribution of sample doesn't change.

Step-by-step explanation:

From central limit theorem, as the size of a sample size increases, the sample mean and sample standard deviation will be far much more closer in value to the population mean(μ) and standard deviation(σ).

Thus, as the size of the sample increases, there will be no changes to the mean of the distribution of the sample mean.

Answer:

The total cost of adding wallpaper to the room is $487.20

Step-by-step explanation:

Basically, how I got the answer is:

1. The shorter sides of the rectangle are 12 and the longer sides are 14.

2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.

3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.

The total cost of adding wallpaper to the room by Mr. Hawkins is $487.20.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given that the shape of the wall that Mr. Hawkins covering with wallpaper is rectangular.

The formula to find the area of a rectangular shape is,

Area of a rectangular shape = Length × Width

Given that,

Length of the wall = 14 feet

Width of the wall = 12 feet

Substituting the given measurements to the formula, we get,

Area of the wall = 14 × 12 = 168 feet²

Also, given that,

Cost for each square foot of wall = $2.90

Cost for 168 square feet = $2.90 × 168

                                        = $487.20

Hence the total cost for adding wallpaper to the room is $487.20.

Answer:

75 mph

Step-by-step explanation:

The speed of Raymond from San Antonio to Dallas is given by S = 75 mph

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed of Raymond from San Antonio to Dallas be S

Let the distance between San Antonio to Dallas be represented as D

Now , the value of D = 390 miles

Let the time taken for Raymond to travel D miles be T = 5.2 hours

Now , the speed is = Distance / Time

On simplifying , we get

The speed of Raymond from San Antonio to Dallas S = D / T

The speed of Raymond from San Antonio to Dallas S = 390 / 5.2

The speed of Raymond from San Antonio to Dallas S = 75 mph

Hence , the speed is 75 miles per hour

The expression t(–1.2w + 3) can be expanded as -1.2wt + 3t.

An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms.

Given expression,

t (-1.2w + 3)

Using distributive property

-1.2wt + 3t

Hence, -1.2wt + 3t is the expanded form of the expression t(–1.2w + 3).

Answer:

Step-by-step explanation:

The quotient id the output of the value when 29 is divided by 118.29

On dividing;

118.6/29 = 4 + {26/29}

4 + {26/29} = 4 + 0.08966

4 + 0.8966 = 4.08966

Hence the best estimate will be the estimate of the value to the nearest one decimal place and that is 4.1.
