240.
Step-by-step explanation:
Here is the correct question: Three sister are getting new outfits. shirts cost 11 each,skirts coat 25 each and shoes cost 44 a pair. what is the total cost of the new outfits for all of the sisters?
Given: Cost of each shirt is 11
Cost of each skirts coat is 25
Cost of each pair of shoes cost is 44.
Now, finding total cost of shirt, skirt coat and shoes as cost of one new outfit.
=
∴ Total cost of one new outfit is 80.
Next, finding cost of new outfit for all, three sisters.
Cost of new outfit for three sister =
∴ Cost of new outfit for three sister =
240 is the total cost of new outfit for all the sisters.
Answer:
1. coefficient of variation(systolic) = 13.88%
2. coefficient of variation(diastolic) = 16.2%
3. The coefficients of variation for each data set are within 5 percentage points of each other Therefore the systolic measurements vary signifcantly less than the diastolic
Step-by-step explanation:
1. Mean of systolic = ( 117+126+158+96+157+122+116+134+127+122)÷10
= 127.5
Standard Deviation of systolic = (((117-127.5)^2 +(126-127.5)^2+(158-127.5)^2+ (96-127.5)^2 + (157-127.5)^2 + (122-127.5)^2 + (116-127.5)^2 +(134-127.5)^2 +(127-127.5)^2 +( 122-127.5)^2) ÷ 10)^(0.5)
SD = 17.7
coefficient of variation(systolic)
= Standard Deviation of systolic /mean of systolic
=
coefficient of variation(systolic) = 13.88%
2. Mean of diastolic = ( 80+77+76+51+90+89+60+64+72+83) ÷ 10
= 74.2
Standard Deviation of diastolic = (((80-74.2)^2 +(77-74.2)^2+(76-74.2)^2+ (51-74.2)^2 + (90-74.2)^2 + (89-74.2)^2 + (60-74.2)^2 +(64-74.2)^2 +(72-74.2)^2 +(83-74.2)^2) ÷ 10)^(0.5)
SD = 12
coefficient of variation(diastolic)
= Standard Deviation of diastolic /mean of diastolic
=
coefficient of variation(diastolic) = 16.2%
3. The coefficients of variation for each data set are within 5 percentage points of each other Therefore the systolic measurements vary signifcantly less than the diastolic
