Formula of finding the distance : absolute value (x2-x1)^2 + (y2-y1)^2
Distance from house to school : (Under Absolute value) (x2-x1)^2 + (y2-y1)^2
( -4 - (-4) )^2 + (10 - 3 )^2 = 0 + 49 = Radical 49 = 7
Distance from house to grocery store : (using the same method) you get = Radical 1200 = 60
Distance from house to community center : (using the same method) =
Radical 85
Yes, the distance from her house to grocery store is greater then to community center
Answer:
2.897
Step-by-step explanation:
Let us find the mean and variance for the sample first.
105 104 110 112
114 106 108 109
Mean = sum/8 = 108.5
Variance = 12
Std dev = sq rt of variance = 3.464
Std error = std dev/ sq rt n
since n =8, we get std error = 1.225
Since sample size is small, df =8-1 =7
For 95% confidence intervals, t critical value for two tailed=2.365
Margin of error = std error x t critical = 1.225(2.365)
=2.897
Answer:
Step-by-step explanation:
According to coulombs law "the force of attraction or repulsion between two charges Q1 and Q2 in a given medium is directly proportional to the product of their charges and inversely proportional to the square of the distance separating them"
where
k = constant of proportionality (
