The table shows data from a survey about the number of times families eat at restaurants during a week. The families are either
Anna11 [10]

Solution:

1. Rome

Minimum=0

Maximum=16

Q_{1}=3, Q_{3}=13, {\text{IQR}=Q_{3}-Q_{1}=13-3=10,

Median ,Q_{2}=8.5

Mean = 8

Standard Deviation(σ)=5.4

As, difference between , Maximum -Mean =Mean - Minimum=8

So, Mean will Worthy description to find the center of Data set, given about Rome.

2. New York

Minimum=1

Maximum=20

Q_{1}=4.5, Q_{3}=6, {\text{IQR}=Q_{3}-Q_{1}=6-4.5=1.5,

Median ,Q_{2}=5.5

Mean = 7.25

Standard Deviation(σ)=6.1

As, for New york , Mean is not the mid value, that is difference between Mean and Minimum is not same as Maximum and Mean.

As, you can see , the three Quartiles , Q_{1},Q_{2},Q_{3} are very close to each other, it means , other data values are quite apart from each other. So, Mean will not  appropriately describe the given data.So, in this case Median will suitable to find the center.

Option (B): The Rome data center is best described by the mean. The New York data center is best described by the median.

Determine whether the given differential equation is separable. StartFraction dy Over dx EndFraction plus 2 sine (x minus y )equ
Natalka [10]

Answer:

dy/dx+2sin(x-y)=0

so whether the given equation is separable or not

dy/dx= -2sin(x-y)

the given equation is not separable because the argument inside the function is dependent on both x and y

even though we use the formula to open the sin(A-B) we would still get the function dependent on both x and y and the equation would get complicated so instead use any other method.
