Use the distributive property to remove the parentheses.
-4(-6y + 2w-4)
Answer: 24y - 8w + 16
Step-by-step explanation:
Basically to remove the parenthesis you just distribute the -4 outside of the parenthesi and you get 24y - 8w + 16.

Which expression is equivalent to (6-2i)(2-3i)?
Answer:
Step-by-step explanation:
(6-2i)(2-3i)=
we will use foil to multiply
-12-18i-4i+6(i^2)=
now remeber that (i^2)=-1
=12-22i-6=6-22i
Explanation: To multiply two complex numbers, use the F.O.I.L method.
So we have (6 - 2i)(2 - 3i).
So we have 12 - 18i - 4i + 6i².
Combining like terms, we have 12 - 22i + 6i².
Now, remember that i² is equal to -1 so we have
12 - 22i + 6(-1) or 12 - 22i - 6 or 6 - 22i.
So our answer is 6 - 22i.
On average, 3 percent of U.S. travelers do not show up for their flight. Suppose this probability is independent and constant across travelers. For a given flight from Seattle to San Francisco, an airline accepted a total of 103 reservations while the plane capacity is 100 seats. What is the probability that the airline will have to bump at least one passenger
Answer:
.3988 .
Step-by-step explanation:
We shall use Binomial distribution formula in the problem .
n = 103
The probability that a passenger will not miss the flight and show up = .97
The probability that a passenger will miss the flight = .03
n = 103 ,
probability of showing up 101 , 102 and 103 passengers so that at least 1 passenger will return or bump .
= 103C₁₀₁ .97¹⁰¹ .03² + 103C₁₀₂ .97¹⁰² .03+ 103C₁₀₃ .97¹⁰³
103 x 102 /2 .97¹⁰¹ .03² + 103 .97¹⁰² .03 + .97¹⁰³
= 5253 x .046 x .0009 + 103 x .00134 + .0434
= .2174 + .1380 + .0434
= .3988 .
The probability that the airline will have to bump at least one passenger is; 0.3988
Binomial probability distributionProbability that the travelers did not show up for the flight is; q = 3% = 0.03
Probability that they will show up for the flight is; p = 97% = 0.97
The formula for binomial probability is;P(X = r) = nCr × p^(r) × q^(n - r)
Thus, the probability that the airline will have to bump at least one passenger is;
(103C₁₀₁ × 0.97¹⁰¹ × 0.03²) + (103C₁₀₂ × 97¹⁰² × 0.03) + (103C₁₀₃ × 0.97¹⁰³ × 0.03⁰)
>> 0.2174 + 0.1380 + 0.0434
>> 0.3988

Answer:
1/9, (-3)/11
Step-by-step explanation:
Both the left and right side are perfect squares,
(x + 2)^2 = (10x + 1)^2
In order for the squares to be equal, we must have the inner expressions equal to each other or negations of each other:
(x + 2) = [tex]\pm[/tex] (10x + 1)
or
x + 2 = -10x - 1
Simplifying the first equation gives 9x = 1 so 1/9 and simplifying the second equation gives 11x = -3, so (-3)/11
Consumer Reports will have an article comparing refrigerators in the next issue. Some of the characteristics to be included in the report are the brand name and model; whether it has a top freezer, bottom freezer, or side-by-side layout; the estimated energy consumption per year (kilowatts); whether or not it is Energy Star compliant; the width, depth, and height in inches; and both the freezer and refrigerator net capacity, in cubic feet. What variables are categorical, and which are quantitative?
Answer:
brand name and model - - > CATEGORICAL
whether it has a top freezer, bottom freezer, or side-by-side LAYOUT - - > CATEGORICAL
the estimated energy consumption per year (kilowatts); - - - > QUANTITATIVE
whether or not it is Energy Star COMPLIANT - - > CAREGORICAL
the width, depth, and height in INCHES - - - > QUANTITATIVE
both the freezer and refrigerator net capacity, in cubic FEET - - - > QUANTITATIVE
Step-by-step explanation:
Given the following refrigerator characteristics :
brand name and model - - > CATEGORICAL
whether it has a top freezer, bottom freezer, or side-by-side LAYOUT - - > CATEGORICAL
the estimated energy consumption per year (kilowatts); - - - > QUANTITATIVE
whether or not it is Energy Star COMPLIANT - - > CAREGORICAL
the width, depth, and height in INCHES - - - > QUANTITATIVE
both the freezer and refrigerator net capacity, in cubic FEET - - - > QUANTITATIVE
To start with ; Categorical and quantitative variables differ most notably in the fact that, quantitative variables deals with numbers, measurements or calculated mathematical values of certain attribute in a measured species or sample. Categorical variable on the other hand mostly deals with making distinctions in properties of a sample by grouping the varibale into the different available categories based on their attributes.
1) A rectangle has the lengths shown
Find the perimeter of the rectangle.
Hi there! :)
[tex]\large\boxed{P = 32cm}[/tex]
Find the perimeter by solving for y.
We know that a rectangle contains two pairs of parallel and congruent sides, therefore:
5y - 1 = 2y + 8
We can solve for y using this expression. Begin by subtracting 2y from both sides:
5y - 2y - 1 = 2y - 2y + 8
3y - 1 = 8
Add 1 to both sides:
3y - 1 + 1 = 8 + 1
3y = 9
Divide both sides by 3:
y = 3
Recall that the perimeter of a rectangle is:
P = 2l + 2w
Plug in the given expressions for the side lengths to find one equation:
P = 2(5y - 1) + 2(y - 1)
Simplify by distribution:
P = 10y - 2 + 2y - 2
Combine like terms:
P = 12y - 4
Plug in the solved value of y into this equation:
P = 12(3) - 4
P = 36 - 4
P = 32 cm.

Alonso signed up for a streaming music service that costs $8 per month. The service
allows Alonso to listen to unlimited music, but if he wants to download songs for
offline listening, the service charges $0.50 per song. How much total money would
Alonso have to pay in a month in which he downloaded 40 songs? How much would
he have to pay if he downloaded s songs?
Answer:
0.5s + 8 is the cost if he downloaded s songs
$28 is the cost for downloading 40 songs
Step-by-step explanation:
First, create an equation to represent the cost where s is the number of songs
Since it is 0.50 per song, the cost per song can be represented by 0.5s. Then, add 8 to this in the equation to represent the monthly fee.
Put this together:
0.5s + 8 is the cost if he downloaded s songs
Plug in 40 as s to find the cost for 40 songs downloaded:
0.5s + 8
0.5(40) + 8
20 + 8
= 28
So, the cost for downloading 40 songs is $28
Answer:
28
Step-by-step explanation:
40 downloaded songs times .50 = 20 dollars plus the 8 dollars he pay every mouth so it's 28 dollars that mouth where he downloaded 40 songs.
y = s x .50 + 8

What is the linear inequality of the graph shown?
Answer:
Tough to tell by just the straight graph, but the inequality will be > or < due to the dashed line
Answer:
y>4x-2
Step-by-step explanation:
Find the slope, which is 4, from (0,-2) and (1,2).
Find the y-intercept, which is -2, because it touches the y-axis at (0,-2).
We know the equation would be a greater/less than sign because the line is dashed.
To find out which sign it is, just substitute a random point from the shaded area. (I like to use (0,0)).
(0)<4(0)-2 (0)>4(0)-2
0<0-2 0>0-2
0<-2 0>-2
The one on the right, 0>-2, is true so the sign is a greater than sign.

Solve the system of linear equations.
y = -2x - 4
y = 2x – 4.
The solution of the linear equations y = -2x - 4 and y = 2x - 4 is (0, -4).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The linear equations are given below.
y = -2x - 4 ...1
y = 2x - 4 ...2
From equations 1 and 2, then we have
2x - 4 = - 2x - 4
4x = 0
x = 0
Then the value of the variable 'y' is calculated as,
y = 2(0) - 4
y = - 4
The solution of the linear equations y = -2x - 4 and y = 2x - 4 is (0, -4).

Answer:
107
Step-by-step explanation:
Since they are congruent triangles angle B is the same as angle D.
To find D, all angles add to 180 degrees, so:
41+32+x=180
73+x=180
X=107
So angle B is 107 degrees
