A certain model of remote-control Stanley garage door opener has nine binary (off/on) switches. The homeowner can set any code sequence. (a) How many separate codes can be programmed
Answers
Answer:
[tex]Codes= 512[/tex]
Step-by-step explanation:
Given
[tex]Switches = 9[/tex]
[tex]Controls = 2[/tex] ------- on or off
Required
Determine the number of codes to be programmed
Since each switch has any of the on or off controls (i.e on or off), then:
The first switch can be coded in any of the 2 controls
The second switch can be coded in any of the 2 controls
The third switch can be coded in any of the 2 controls
Up till the ninth switch
So, we have that:
[tex]Codes= 2 * 2 *2*2*2* 2 *2*2*2[/tex]
[tex]Codes = 2^9[/tex]
[tex]Codes= 512[/tex]
Hence, there are 512 possible codes

Understand the question explain and u will be brainiest
Answers
This is because the question asks if a student DOES NOT have any pets, so you find the total outside of the ‘has pets’ area. This is 30 that have siblings and 5 which do not:
30+5 = 35
Then the question asks for the probability that they DO NOT have siblings so that is 5 people.
5/35 = 1/7

Priya ran 1 1/2 miles today, and Tyler ran 3 3/4 miles. How many times the length of Priya’s run was Tyler’s run?
Answers
Answer:
2.5
Step-by-step explanation:
The length of Priya’s run was 2.5 times Tyler’s run.
Given
Priya ran 1 1/2 miles today, and Tyler ran 3 3/4 miles.
To determine how many times the length of Priya’s run was Tyler’s run following all the steps given below.
Let, the distance covered by Priya be x and Tyler be y.
Priya ran 1 1/2 miles today.
Then,
[tex]\rm = 1 \dfrac{1}{2}\times x\\\\= \dfrac{2\times 1+1}{2}\times x\\\\= \dfrac{2+1}{2}\times x\\\\=\dfrac{3x}{2}[/tex]
Tyler ran 3 3/4 miles.
[tex]\rm = 3 \dfrac{3}{4}\times y\\\\= \dfrac{4\times 3+3}{4} \times y\\\\= \dfrac{12+3}{4} \times y\\\\= \dfrac{15y}{4}[/tex]
On comparing both the distance
[tex]\rm \dfrac{3}{2} \times x= \dfrac{15}{4}\times y\\\\x = \dfrac{5y}{2} \\\\x = 2.5y[/tex]
Hence, the length of Priya’s run was 2.5 times Tyler’s run.

Joanne designs and sells t shirts through an online forum. she paid 80 dollars for general supplies. It costs her 2 dollars to make each t shirt. She charges 6 dollars per shirt. Determine how many t shirts Joanne needs to sell in order to break even.
Answers
Answer:
20 shirts
Step-by-step explanation:
We are told she paid 80 dollars for general supplies. It costs her 2 dollars to make each t shirt.
Total cost of production is;
80 + 2t
Where t is number of t-shirts.
We are told that She charges 6 dollars per shirt.
This means that total revenue from sales is; 6t
Now,in economics or business, break even point is the point where revenue and total cost are equal.
Thus, break even point will be at;
80 + 2t = 6t
6t - 2t = 80
4t = 80
t = 80/4
t = 20 shirts
