- 2x + 4 for x = - 3, 0 , and 3.
Answer:
when x=-3 y=10
when x=0 y=4
when x=3 y=-2
Step-by-step explanation:
all you have to do is plug in -3 0 and 3 for x
-2(-3)=6
6+4=10 so when x=-3 y=10
-2(0)=0
0+4=4
so when x=0 y=4
-2(3)=-6
-6+4=-2
so when x=3 y=-2

A worker is paid Rs 1110 for 6 days. If he told wage during a month is Rs 4625, for how many days did he work?
Worker work for =25 days and he paid Rs.4625.
Step-by-step explanation:
From the question,
Worker is paid Rs.1110 for =6 days
Worker is paid Rs.1 for =(6/110) days
Worker is paid Rs.4625 for =(6/1110)×(4625) days
=25 days

Answer: The relation is a function.
Step-by-step explanation: Since there is one value of y for every value of x in (-2,4), (3,7), (0,8), (5,8), and (1,6), this relation is a function.

Let the random variable H represent the height of a woman in the population. P(H<60) represents the probability, of randomly selecting a woman with height less than 60 inches. Based on the information given, the probability can be found using either the discrete model for the normal model.
Answer:
Hello your question in incomplete attached below is the complete question
answer : 0.03
Step-by-step explanation:
H represents the height of women
Determine P ( H < 60 ) using either discrete or normal model
using discrete model
P ( H < 60 ) = ∑ relative frequencies of women with height < 60 inches
= 0.01 + 0.02 = 0.03

Calculate the gradient of the line using rise/run method.
Given:
The graph of line.
To find:
The gradient of the line using rise/run method.
Solution:
We know that the gradient of a line is also known as slope.
[tex]Slope=\dfrac{Rise}{Run}[/tex]
Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.
[tex]Rise=-3[/tex]
[tex]Run=2[/tex]
Now,
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{-3}{2}[/tex]
The gradient of the line is [tex]-\dfrac{3}{2}[/tex].
Therefore, the correct option is C.
3. A company makes a profit of $15 per software program and $10 per video game. The company can produce
at most 70 software programs and at most 80 video games per week. Total production cannot exceed 100
items per week. How many items of each kind should be produced per week in order to maximize the profit?
Use linear programming to solve. Show all your work.
Answer:
For the profit to be maximized, 20 software programs and 80 video games should be produced
Step-by-step explanation:
Let x represent the number of the software programs and let y represent the number of video games.
We are told that the company can produce at most 70 software programs and then, at most 80 video games per week. Thus;
x ≤ 70
y ≤ 80
Also, we are told that the overall production cannot exceed 100. Thus;
x + y ≤ 100
Since the company makes a profit of $15 per software program and $10 per video game. Then, the function to be maximized is;
15x + 10y
When they produce at most 70 software programs, it means that the number of video games that can be produced is: 100 - 70 = 30.
Thus, one point of maximizing values is; (70, 30)
Also, when they produce at most 80 video games per week, the number of software programs that can be produced is; 100 - 80 = 20.
Thus, second point of maximization is;
(20, 80)
Putting these points into the objective function, we have;
At (70, 30); 15(70) + 10(30) = $1350
At (20, 80); 15(20) + 10(80) = $1100
For the profit to be maximized, 20 software programs and 80 video games should be produced

2. Celeste was selling meal tickets for the holiday program at her school. The
cost of a dinner ticket is $10. She is also selling dessert tickets for $6. She lost
track of how many of each ticket she sold; however, she remembered that she
was given 100 tickets and she collected $900. The system of equations shown
can be used to represent this situation: Part A: What does the variable x
represent in this system of equations?
A. The number of dinner tickets sold.
B. The number of dessert tickets sold.
C. The number of dollars collected for dinner tickets.
D. The number of dollars collected for dessert tickets. ption 1
Answer:
A. The number of dinner tickets sold.
Step-by-step explanation:
Celeste was selling meal tickets for the holiday program at her school. The
cost of a dinner ticket is $10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold; however, she remembered that she was given 100 tickets and she collected $900.
Let us represent
Number of dinner tickets = x
Number of dessert tickets = y
From the above question, our system of equations is given as:
x + y = 100...... Equation 1
$10 × x + $6 × y = $900
10x + 6y = 900...... Equation 2
Therefore, the variable x in this system of equations represents the number of dinner tickets sold.

The ratio 2 centimetres to 5 metres can be written in the form
1
:
n
.
Find the value of
n
.
Answer:
n = 250
Step-by-step explanation:
To express the ratio, the quantities must have the same measures
2 cm : 5 m
= 2 cm : 500 cm [ 1 m = 100 cm ]
Divide both parts by 2
= 1 : 250 → with n = 250
