Answer:
√10
Step-by-step explanation:
√(x2-x1)^2+(y2-y1)^2=√10
Answer:
The resistance is 7.5 ohms
Step-by-step explanation:
V = IR
V = voltage I is the current and R = resistance
120 = 16*R
Divide by 16 on both sides
120/16 = 16R/16
7.5 = R
The resistance is 7.5 ohms

Answer:
2.23 this the answer use the calculator
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
