Answer:
125.66cm²
Step-by-step explanation:
so you need to find the area of the big circle and subtract it from the area of the small circle
area of a circle= π r²
small circle: substitute in what you know
a= π x 3²
a= 28.2743
big circle: substitute in what you know
a= π x 7²
a= 153.9380
now do 153.9380-28.2743=125.6637
now round this number to the nearest hundredth:
125.66cm²
Answer:
216
Step-by-step explanation:
Since a=-6,b=-4 and c= 3,we have to multiply them including the extra three
Answer:
Bob performed better in mathematics part of the SAT than the ACT
Step-by-step explanation:
We need to calculate the z-scores for both parts and compare them.
Z-score for the SAT is calculated using the formula:
where 
is the mean and 
is the standard deviation, and 
is the SAT test score.
We plug in these values to obtain:
to the nearest hundredth.
We use the same formula to calculate the z-score for the ACT too.
Where 
is the mean and 
is the standard deviation, and 
is the ACT test score.
We substitute the values to get:
to the nearest hundredth.
Since 1.29 > 1.25, Bob performed better in mathematics part of the SAT
