Answer:
18.21 cm^2.
Step-by-step explanation:
Area of the unshaded part
= area of the square - area of the quadrant
= 7^2 - 1/4 pi *7^2
= 49 - 30.788
= 18.21 cm^2.
- The answer is, The means differ by only about 0.5, but the standard deviations shows that the hurricanes' number of points is generally closer to the mean.
Step-by-step explanation:
- Red hawks and Hurricane in two columns.
- Total of both Red hawks and Hurricane 725 and 716.
- Mean is the measure of centrality.
- Mean = Adding total number of points / by games played.
- Formula is Ex/N.
- Result mean of Red hawks and Hurricane is 45.31 and 44.75.
- The difference between the mean is 0.56 as mentioned.
- Standard deviation shows, how much of data is away from mean.
- Standard deviation shows the variability of data.
- Standard deviation of Red hawks and Hurricane is 8 and 4.
- Red hawks is 8 further away from mean.
- Hurricane is 4 further away from mean.
- Hurricane is closer because they are consistent.
30%
percent means parts out of 100 so 30%=30/100=3/10
42 is 3/10 of x
'of' can be translated to multiply
42=3/10 times x
multiply both sides by 10/3 to get rid of fraction
420/3=x
140=x
the number is 140
Since a serving is 1/2 cup and he needs 72 servings you can multiply 72 by 1/2 and find out that he needs to make 36 cups of punch. Two cups is a pint so he needs (36 / 2) 18 pints of juice. He already has the 8 pints of pineapple juice so 18 - 8 leaves 10 pints of orange juice.
