Answer:
8
Step-by-step explanation:
d=√(−5−3)2+(−2−(−2))2
d=√(−8)2+(0)2
d=√64+0
d=√64
d=8
W X = 83
W Y = 119
X Y = 36
W X = 3y + 11
W Y = 6y - 25
X Y = y + 12
-For a known standard deviation, the sample size for a desired margin of error is calculated using the formula:
Where:
We substitute our given values to calculate the sample size:
Hence, the smallest desired sample size is 23
12.8, 11.6, 10.4, 9.2, 8.0, 6.8, 5.6
3, 1.5, 0.75, 0.375, 0.1875, 0.09375, 0.046875
The first one is arithmetic as the pattern is deducting 1.2, second one is geometric as it is dividing 2.
15=13
15=-6 you solve the left side, 7+6 which is 15?
15=-6 =
7+6 = 13
i'm not sure...
The answer is C
