Answer:
3.14
Step-by-step explanation:
A=π*r^2
3.14*(2^2)
3.14*4
12.56/4 (because it's 1/4th a circle)
3.14.
Answer is B.
Standard deviation is a measure of spread in statistics which tells about how the data is clustered around or close to the mean. There is a quick rule known as the Range Rule of Thumb by which we can estimate the standard deviation. According to the range rule of thumb, the range is approximately four times the standard deviation.
s ≈ R4
To use this rule, we may first find the range by subtracting the smallest value from the greatest value: 45 - 18 = 27
now divide the range by 4 to estimate the standard deviation:
s = 27/4 = 6.75 ≈ 6.8
I believe the answer would be that 0.09375 of 2 1/4 cups of flour would go into each cookie because:
2 dozen = 24 cookies
Therefore...
2 1/4 divided by 24 = 0.09375
I'm not sure if this is correct but I hope this may help. :))
Answer:
I think by using a prime factor tree
2.35 * 10^-4 move the decimal 4 places to the left
.000235
6.5 * 10^-3
move the decimal 3 places to the left
.0065
7.07*10^-5
move the decimal 5 places to the left
.0000707
