In order to simplify a fraction, we have to find a common factor in both numerator and denominator. So, let's start by factor the expressions completely: at the numerator we have
At the denominator we have
So, the fraction can be written as
You can see that there is a factor in common, that can be simplified:
Answer:
A dot plot is like a histogram but it uses dots instead of bars. Like histogram, a dot plot also presents the frequency of data points. The dot plot as described by the problem is shown in the picture. A bell shape is drawn for a symmetrical data. From the choices, the answer is: It is symmetric and has no gaps. The other statements are wrong because the peak is at $5 or $6.
As it is perimeter you would have to multiple by 2 for both as l and w are the same on both sides 2(5x-4) + 2(4x-5)
Answer:
No
Step-by-step explanation:
They are not the same size.
The average speed of the family during their walk will be 1.4 km per hour.
<h3>What is the average speed?</h3>
The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. Its unit is a meter per second or Km per hour.
Given that over a 1.35-hour period of time, a family walk 0.75 km, stop to talk to the neighbor, and then walk another 1.15 km before reaching their destination.
The average speed will be calculated as:-
Average speed = Total distance / Total time
Average speed = ( 1.15 + 0.75 ) / 1.25
Average speed = 1.4 km per hour.
Therefore, the average speed of the family during their walk will be 1.4 km per hour.
