Step-by-step explanation:
The given data set is:
Week 1: 600
Week 2: 300
Week 3: 500
Week 4: 900
The following are the steps to find the standard deviation:
Step 1. Jim enters the data and calculates the average or mean.
Step 2. Jim calculates the deviation from the mean by subtracting the mean from each value.
Data value (x)
600 25
300 -275
500 -75
900 325
Step 3. Jim squares each deviation to remove negative signs.
Data value (x)
600 625
300 75625
500 5625
900 105625
Step 4. Jim sums the squares of each deviation and divides by the count for the variance.
Step 5.Jim takes the square root of the variance to find the standard deviation.
Answer:
The cost of one small box of fruit is $5.00 and the cost of one large box of fruit is $15.50
Step-by-step explanation:
Let
x ----> the cost of one small box of fruit
y ----> the cost of one large box of fruit
we know that
Ahmed
Ahmed sold 24 small boxes of fruit and 14 large boxes of fruit for a total of $337.00.
so
-----> equation A
Christy
Christy sold 21 small boxes of fruit and 16 large boxes of fruit for a total of $353.00
so
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (5,15.5)
see the attached figure
therefore
The cost of one small box of fruit is $5.00 and the cost of one large box of fruit is $15.50
The greatest common factor would be c
The LCM (lowest common multiple) of 4 and 5 is 20, so convert them so that the denominator is 20:
3/4 = 15/20
2/5 = 8/20
I didn't quite read the question properly, but regardless. Since only 15/20 of the batch has raisins, of which only 8/20 has nuts, we can formulate this equation to solve:
1x15/20x8/20
=3/10
