I'm unsure how to solve this equation, but it appears to be the correct one
A sequence for this rule can be established by beginning with the number one and consistently applying the rule to each following number: 1 x 3 + 2 = 5, 5 x 3 + 2 = 17, 17 x 3 + 2 = 53, etc.
Answer:
3 hours
Step-by-step explanation:
The temperature change after an hour shows an increase of 5 degrees. To calculate how long it takes to reach 60 degrees, we first find the difference from the current temperature to 60 degrees.
60 - 45 = 15 degrees
Since a rise of 5 degrees occurs in one hour, we divide 15 by 5 to find out how many hours are needed to reach 60 degrees.
15 / 5 = 3 hours
Answer:
The median value is 47.
Step-by-step explanation:
First, organize the numbers in ascending order.
The median's position is calculated as ((N+1)÷2)th term, where N is the amount of data.
= 6÷2 th term
= 3 rd term
<ptherefore the="" term="" is="" identified="" as="">
</ptherefore>
