Determine whether the data described are discrete or continuous. The number of pixels in a cellphone display.
Answers
Answer:
Discrete
Step-by-step explanation:
The random variable that can be counted is known as discrete random variable. The number of pixels in cell phone display is a discrete variable. The reason is that the number of pixels is countable and can be represented by whole number. Also, the number of pixels are finite and can be counted so it is a discrete variable.
Final answer:
The number of pixels in a cellphone display is a discrete data set because the number of pixels can only take on countable and finitely limited values.
Explanation:
The data you are referring to, the number of pixels in a cellphone display, would be considered discrete. This is because the values this data can assume are countable and limited. For instance, a screen could have 2000, 3000, or 4000 pixels, but not 2000.5. In contrast, continuous data is data that can take any value within a certain range, usually represented by an interval on the number line which includes fractions and decimals.

Answer:
11 am
Step-by-step explanation:
Bus A and Bus B leave the bus depot at 9 am.
Bus A takes 30 minutes to complete its route once
Bus B takes 40 minutes to complete its route once.
We solve this finding the Lowest Common Multiple of the minutes each bus uses to complete it's route
30 = 3 × 10
40 = 4 × 10
= 3 × 4 × 10
= 120 minutes
120 minutes after 9 am is
60 minutes = 1 hour
60 minutes = 1 hour
= 2 hours.
9am + 2 hours
= 11 am.
Therefore, they be back at the bus depot together at 11 am

2) here you must us pq-formel as:
5m^2-5m=60
5m^2-5m-60=0
(m^2-5m-60)/5=0
m^2-m-12=0
m=0,5(+-) the root of 0,25+12
m=0,5(+-)3,5
m1=0,5+3,5
m2=0,5-3,5
15) x^2=7x
x^2-7x=0 here there is two x, so:
x(x-7)=0
x1=0
x2=7
Here you can only use PQ formula in all the others, just as I did in the question number 2
