−8x−7
EXPAND
−8x−7
Step-by-step explanation:
SOLUTION STEPS
(−6x−11)−(2x−4)
To find the opposite of 2x−4, find the opposite of each term.
−6x−11−2x−(−4)
The opposite of −4 is 4.
−6x−11−2x+4
Combine −6x and −2x to get −8x.
−8x−11+4
Add −11 and 4 to get −7.
−8x−7

Answer:
decimal format = 29.25mixed number = 29 1/4Improper fraction = 117/4Step-by-step explanation:
Make the denominators equal after simplifying the denominators*. The denominators are currently 2 and 4. So you can just make your life easier by making the denominator of the first number a 4. Multiply both sides by 2.
1. Simplify
12*2+1 = 25/2
25/2*2/2 = 50/4
2. Simplify second number
16*4+3 = 67/4
3. Add the improper fractions
50/4 + 67/4 = 117/4
Total answer:29.25 = decimal formatmixed number = 29 1/4Improper fraction = 117/4Terms:

The weekly amount spent by a small company for in-state travel has approximately a normal distribution with mean $1450 and standard deviation $220. What is the probability that the actual expenses will exceed $1560 in 20 or more weeks during the next year?
Answers
Answer:
0.0903
Step-by-step explanation:
Given that :
The mean = 1450
The standard deviation = 220
sample mean = 1560
[tex]P(X > 1560) = P( Z > \dfrac{x - \mu}{\sigma})[/tex]
[tex]P(X > 1560) = P(Z > \dfrac{1560 - 1450}{220})[/tex]
[tex]P(X > 1560) = P(Z > \dfrac{110}{220})[/tex]
P(X> 1560) = P(Z > 0.5)
P(X> 1560) = 1 - P(Z < 0.5)
From the z tables;
P(X> 1560) = 1 - 0.6915
P(X> 1560) = 0.3085
Let consider the given number of weeks = 52
Mean [tex]\mu_x[/tex] = np = 52 × 0.3085 = 16.042
The standard deviation = [tex]\sqrt {n \time p (1-p)}[/tex]
The standard deviation = [tex]\sqrt {52 \times 0.3085 (1-0.3085)}[/tex]
The standard deviation = 3.3306
Let Y be a random variable that proceeds in a binomial distribution, which denotes the number of weeks in a year that exceeds $1560.
Then;
Pr ( Y > 20) = P( z > 20)
[tex]Pr ( Y > 20) = P(Z > \dfrac{20.5 - 16.042}{3.3306})[/tex]
[tex]Pr ( Y > 20) = P(Z >1 .338)[/tex]
From z tables
P(Y > 20) [tex]\simeq[/tex] 0.0903

The net force is the vector sum of all of the forces acting on an object. To find the net force when there are two opposite forces subtract the smaller number from the larger, for example, 7-2. Then take to total, 5N, and add the direction of the stronger force. If the equation equals zero that means you have a balanced force. To find the force of two actions in the same direction simply add them.

A school is installing a flagpole in the central plaza. The plaza is a square with side length 100 yards as shown in the figure below. The flagpole will take up a square plot in the middle of the plaza and its base will have an area of x^2−6x+9 yd^2.
Area of the flagpole plot: x^2−6x+9
Find the length of the base of the flagpole by factoring. (Hint: Because the area of the flagpole is an expression that involves the variable x, the length of the base will also involve the variable x.)
The length of the base of the flagpole is
Answers
Answer:
[tex]x-3[/tex]
Step-by-step explanation:
The area of the flagpole base is [tex]x^2-6x+9\ \text{yd}[/tex]
where the factor of the equation is the length of the base.
In order to find the length we need to factorize the equation
[tex]x^2-6x+9[/tex]
[tex]=x^2-3x-3x+9[/tex]
[tex]=x(x-3)-3(x-3)[/tex]
[tex]=(x-3)(x-3)[/tex]
The length of the base of the flagpole is [tex](x-3)\ \text{yd}[/tex].
The area of a square base is the product of the side lengths.
The length of the base is x - 3
The area is given as:
[tex]\mathbf{Area =x^2 - 6x + 9}[/tex]
Expand
[tex]\mathbf{Area =x^2 - 3x - 3x + 9}[/tex]
Factorize
[tex]\mathbf{Area =x( x- 3) - 3(x - 3)}[/tex]
Factor out x - 3
[tex]\mathbf{Area =( x- 3) (x - 3)}[/tex]
Express as squares
[tex]\mathbf{Area =( x- 3)^2}[/tex]
Rewrite the area as:
[tex]\mathbf{Length^2 =( x- 3)^2}[/tex]
Take square roots of both sides
[tex]\mathbf{Length =x- 3}[/tex]
Hence, the length of the base is x - 3
