Answer:
The first step is to slove the numbers in the brackets
Step-by-step explanation:
[(x+7) x -2] / 4 = 7
-2(x+7) / 4 = 7
-2x-14 / 4 = 7
-2x-14 = 28

Step-by-step explanation:
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

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.

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
It's for middle School PLZZZZ HELPPPP.
Lauren and her brother are buying their mom a watch for her birthday. The original price of the watch is $50, but the store is having a 25% off sale on watches. The sales tax in Lauren’s state is 6%.
How much will Lauren and her brother pay for the watch including tax? How much will each sibling pay if they split the cost equally?
Answer:
$20
Step-by-step explanation:
To find out sale
50 x .25 = 12.5
To find out tax
37.5 x .06 = 2.25
Then final price
37.5 + 2.25 = 39.75
If they spilt price
$19.88
Answer:
1. $37.5 without tax
2. Split bill with tax: $19.88
3. Split bill withput tax: $18.25
Step-by-step explanation:
Make an equation first.
y=.25 (50)
This would help solve the amount for the discpunt sale.
The discout is $12.5 off.
50-12.5=37.5
Now we have tp solve for the tax amount.
y=0.06 (37.5)
y=2.25
2.25 is the tax amount.
We have to add these all together to get the answer for part 1.
37.5+2.25= $39.75

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.

A tree casts a shadow 7.5 feet long at the same time that a 5 foot tall woman casts a shadow 3 feet long. How tall is the tree?
Answer:
The tree is 12.5ft Step-by-step explanation: 1. TREE'S HEIGHT over TREE'S SHADOW equals WOMAN'S HEIGHT over WOMAN'S SHADOW
2. TREE'S HEIGHT over WOMAN'S HEIGHT equals TREE'S SHADOW over WOMAN'S SHADOW
or some other ways as long as you pair them up by 'height', or pair them up by
'shadow'. {But don't get them criss-crossed)
Let TREE's HEIGHT = t.
A tree casts a shadow 7.5 ft long
TREE'S SHADOW = 7.5
at the same time that
a woman 5 ft tall
WOMAN'S HEIGHT = 5
casts a shadow 3 ft long.
WOMAN'S SHADOW = 3
So if you use
1. TREE'S HEIGHT over TREE'S SHADOW equals WOMAN'S HEIGHT over WOMAN'S SHADOW
cross-multiply:
3t = 37.5
t = 12.5
or if you use
2.cross-multiply
3t = 37.5
t = 12.5
Either way, the tree is 12.5 feet tall.

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.
Simplify:
з (2(3) + (4 — 2)(3) - (6 – 2)(2)]

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

American households increasingly rely on cell phones as their exclusive telephone service. It is reported that 53.0% of American households still have landline phone service. We decide to randomly call eight households and ask if the home has a landline phone.
Required:
a. What is the random variable?
b. What is the probability that none of the households in the sampled group have landline phone service?
c. What is the probability that exactly five of the households in the sampled group have a landline phone service?
Solution :
a). According to the reports, 53.0% of the American households still have a landline phone service. Out of which 8 households are randomly called.
Here, the landline phone service is p = 53.0%
n = 8
Therefore, q = 1 - p
= 1 - 0.53
= 0.47
here we use the binomial distance because the probability of having the landline phone service is constant and the number of the trial are finite.
b). Let x be the number of household in the sample group having landline phone service.
Probability that none of the household in the sample group have a landline service is
= P( x = 0)
[tex]$=^8C_0 (0.53)^0(0.47)^8$[/tex]
= 0.002 (using the binomial calculation )
c). Probability that exactly 5 of the household in the sample have a landline service is given by :
P(x = 5)
[tex]$=^8C_5 (0.53)^5(0.47)^3$[/tex]
= 0.24

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).
