Kimberly is measuring the temperature fluctuations of a city
1 answer:
Answer:
Easy Peasy!
Step-by-step explanation:
First we have to set up our equation:
(Let x= Temp. after 5 days)
Sorry, have to define variables. If I didn't do it in Middle School Tests, I get an automatic 0 for that question.
So, let's solve!
(If you didn't know what I did there, I just multiplied the rate of the decreasing and increasing temperature by the number of days it was in effect)
So, the temperature during the fifth day is 58.2 degrees.
Hope this helps!
P.S. Stay Safe!

The probability of choosing two yellow marbles = 5/26
Step-by-step explanation:
Step 1 :
Given
Total number of marbles in the bag = 13 marbles
Number of yellow marbles = 6.
We choose 2 marbles from the bag without replacing and need to determine the probability that both are yellow.
Step 2 :
Probability of finding yellow marble in the first try = Number of yellow marbles / Total number of marbles =
Once the yellow marble is selected we have 5 yellow marbles among 12 remaining marbles in the bag.
Probability of finding yellow marble in the second try = Number of yellow marbles / Total number of marbles =
Step 3:
P(yellow in first 2 tries) = P(yellow in first try) * P(yellow in second try)
P(yellow in first 2 tries) = =
Step 4:
Answer:
The probability of choosing two yellow marbles = 5/26
