Answer:
(A) the addition property of equality and then the division property of equality
Step-by-step explanation:
To get from Step 1 to Step 2, we have added 5 to both sides of the equation:
-3x -5 +5 = 13 +5
-3x = 18
To get from Step 2 to Step 3, we have divided both sides of the equation by -3:
-3x/-3 = 18/-3
x = -6

What is the range?
Answers
Answer:
- 4, - 1, 2, 5
Step-by-step explanation:
To find the range, simply substitute each of the domains into the function to get the y-values.
f(-2) = 3(-2) + 2
= - 6 + 2
= - 4
f(- 1) = 3(-1) + 2
= - 3 + 2
= - 1
f(0) = 3(0) + 2
= 0 + 2
= 2
f(1) = 3(1) + 2
= 3 + 2
= 5
The range is - 4, -1, 2, 5.

Answers
Answer:
#2) 6,440 kilograms
The density of steel is 8,050 kilograms per cubic meter. A construction company is using a steel beam in the shape of a rectangular prism that measures 12 meters long, 1/5 of a meter wide, and 1/3 meter deep then the mass of the steel beam is 6,440 kilograms Option b.
To find the mass of a steel beam.
Let's start by defining the variables we have:
- The density of steel, denoted by "ρ" (rho), is given as 8,050 kilograms per cubic meter (kg/m³).
- The dimensions of the steel beam are:
- Length (L) = 12 meters (m)
- Width (W) = 1/5 meter (m)
- Depth (D) = 1/3 meter (m)
We want to find the mass (m) of the steel beam. The mass of an object can be calculated using its density and volume:
M = ρ [tex]\times V[/tex]
Here, "V" represents the volume of the steel beam. The volume of a rectangular prism (like the steel beam) is calculated as:
[tex]\[ V = L \times W \times D \][/tex]
Substitute the given values:
[tex]\[ V = 12 \, \text{m} \times \frac{1}{5} \, \text{m} \times \frac{1}{3} \, \text{m} \][/tex]
[tex]\[ V = 12 \, \text{m} \times \frac{1}{5} \times \frac{1}{3} \, \text{m} \][/tex]
[tex]\[ V = \frac{12}{5} \times \frac{1}{3} \, \text{m}^3 \][/tex]
[tex]\[ V = \frac{12}{15} \, \text{m}^3 \][/tex]
[tex]\[ V = \frac{4}{5} \, \text{m}^3 \][/tex]
Now that we have the volume, we can find the mass of the steel beam using the given density:
[tex]\[ m = 8,050 \, \text{kg/m}^3 \times \frac{4}{5} \, \text{m}^3 \][/tex]
[tex]\[ m = \frac{8,050 \times 4}{5} \, \text{kg} \][/tex]
[tex]\[ m = \frac{32,200}{5} \, \text{kg} \][/tex]
[tex]\[ m = 6,440 \, \text{kg} \][/tex]
After performing the calculations, we find that the mass of the steel beam is 6,440 kilograms. Therefore, the correct answer is option Option b 6,440 kilograms.

New legislation passed in 2017 by the U.S. Congress changed tax laws that affect how many people file their taxes in 2018 and beyond. These tax law changes will likely lead many people to seek tax advice from their accountants (The New York Times). Backen and Hayes LLC is an accounting firm in New York state. The accounting firms believe that it may have to hire additional accountants to assist with the increased demand in tax advice for the upcoming tax season. Backen and Hayes LLC has developed the following probability distribution for x= number of new clients seeking tax advice.x f(x)20 .0525 .2030 .2535 .1540 .1545 .1050 .10a. Is this a valid probability distribution? Explain.b. What is the probability that Backens and Hayes LLC will obtain 40 or more new clients?c. What is the probability that Backens and Hayes LLC will obtain fewer than 35 new clients?d. Compute the expected value, variance, and standard deviation of x.
Answers
Answer:
a. Yes
b. 0.35
c. 0.5
d.
E(x)=34.25
V(x)=73.1875
SD(x)=8.555
Step-by-step explanation:
a.
x 20 25 30 35 40 45 50
f(x) 0.05 0.2 0.25 0.15 0.15 0.1 0.1
This will be valid probability distribution if
1. All probabilities are between 0 and 1 inclusive.
2. Sum of probabilities must be 1.
Condition 1 is satisfied in this distribution. Now, we will check second condition
sum(f(x))=0.05+0.2+0.25+0.15+0.15+0.1+0.1=1.
As the both conditions are satisfied, thus the given distribution is a valid probability distribution.
b.
P(x≥40)=P(X=40)+P(X=45)+P(X=50)
P(x≥40)=0.15+0.1+0.1
P(x≥40)=0.35
So, the probability that Backens and Hayes LLC will obtain 40 or more new clients is 0.35.
c.
P(x<35)=P(X=20)+P(X=25)+P(X=30)
P(x<35)=0.05+0.2+0.25
P(x<35)=0.5
So, the probability that Backens and Hayes LLC will obtain fewer than 35 new clients is 0.5.
d.
Expected value of x=E(x)= sum[x*f(x)]
E(x)= 20*0.05+25*0.2+30*0.25+35*0.15+40*0.15+45*0.1+50*0.1
E(x)=1+5+7.5+5.25+6+4.5+5
E(x)=34.25
Variance of x=V(x)=sum[x²*f(x)]-(sum[x*f(x)])²
sum[x²*f(x)]= 20²*0.05 +25²*0.2 +30²*0.25 +35²*0.15 +40²*0.15 +45²*0.1 +50²*0.1
sum[x²*f(x)]=20+1255+225+183.75+240+202.5+50
sum[x²*f(x)]=1246.25
V(x)=1246.25-(34.25)²
V(x)=73.1875
Standard deviation of x=SD(x)=√V(x)
SD(x)=8.555

Andrew and his children went into a grocery store and he bought $12 worth of
apples and bananas. Each apple costs $1 and each banana costs $0.60. He
bought a total of 16 apples and bananas altogether. By following the steps
below, determine the number of apples, x, and the number of bananas, y,
that Andrew bought.
Answers
1(X) + 0.60y =12
I used the process of elimination.
Subtract everything.
0.40y = 4
Then divide
Y= 10
Therefore, he bought 10 bananas and 6 apples.
The number of apples and bananas andrew and his children bought is 6 and 10 respectively.
Andrew and his children bought $12 worth of apples and bananas. Each apple costs $1 and each banana costs $0.60. He bought a total of 16 apples and bananas altogether.
Let number of apples = x and number of bananas is x-16
What is arithmetic?
In mathematics it deals with numbers of operations according to the statements.
Here,
x*4 + 0.60(16-x) = 12
0.4x + 9.6 = 12
0.4x = 2.4
Number of apples, x = 6
And number of bananas = 16 -x
= 16 - 6
= 10
Thus, the number of apples and bananas andrew and his children bought is 6 and 10 respectively.

Answers
Answer:
a. Function
b. Function
c. Not a function
Step-by-step explanation:
Here is a basic rule to determine if a relation is a function of not:
1. A function has only one exact y-value (range) assigned to each x-value (domain).
2. A x-coordinate value is not repeated in a function, however, a y-coordinate value can be repeated. This means, the same y-value can be assigned to different x-values.
Bearing these in mind, let's label the given representation accordingly:
a. There is exactly one y-value assigned to each x-value, and also, no x-value is repeated. Therefore, it is a function.
b. The graph shows a repeating y-value, however, each x-value has exactly one y-value assigned to it. Therefore the graph represented is a function.
c. The table shows a repeating x-values. This is definitely not a function.

[tex]\frac{20}{sinA}[/tex] = [tex]\frac{29}{sin82}[/tex] ( cross- multiply )

Answer:
(a) 3, (b) 96, (c) No
Step-by-step explanation:
(a) Since we have [tex]p = 150 - 6q^2[/tex] and [tex]p = 10q^2 + 2q[/tex], we can set up a quadratic equation by [tex]150 - 6q^2 = 10q^2 + 2q[/tex], moving all values to one side.
The equation is: [tex]16q^2 + 2q - 150 = 0[/tex].
Let's use the quadratic formula to find q,
we obtain that [tex]q = 3[/tex] or [tex]q = -3.125[/tex]
We can ignore [tex]-3.125[/tex] because supplying a negative quantity is impossible.
Hence, the answer of (a) is 3
(b) Simply substitute [tex]q = 3[/tex] into either equations given in the question to find p, and the answer of (b) is 96.
(c) We want to find if there is an exact quantity that makes the TR exactly 1500.
We substitute TR = 1500,
[tex]1500 = 85q - 2q^2[/tex]
Use the quadratic formula again, and we will find that the answer is "undefined".
As a result, there is not output level in which the total revenue is exactly 1500.
