1. Summarize the data given.
You know that you made $51 in just one day. You charge $9 for going to their house, plus $6 hours for raking.
9 + 6x = 51
X = The Hours Spent Raking
2. Turn the equation so then 6x is by itself.
9 + 6x = 51
-9 -9
6x = 42
3. Remove the number, so x remains by itself.
6x = 42
/6 /6
x = 7
So that means, you spent 7 hours raking leaves on the day I made 51 dollars.
Answer:
6
Step-by-step explanation:
To find the median you simply look for the number in the middle of the list.
In this particular case 1 and 11 are both the fifth number in the series of numbers. When this happens you have to add the two terms together (1+11) and divide by two (12/2)=6
Answer:
There are 21 blue marbles
Step-by-step explanation:
In this question, we are asked to calculate the number of blue marbles in a bag that contains a total of 60 marbles, given the probability of choosing a blue marble.
Mathematically, the probability of choosing a blue marble can be represented as:
P(B) = number of blue marbles/ Total number of marbles
From the question, we can identify that P(B) is 0.35, number of Marbles is unknown while the total number of marbles is 60.
We insert these values in the equation;
0.35 = number of blue marbles/60
Hence, number of blue marbles = 60 * 0.35 = 21
