Answer:
well it might take some time to get used to going on the work and doing it. then soon or later you will be used to going on online classes
Step-by-step explanation:
C^2=a^2+b^2
a=x
c=9
b=7
9^2=x^2+7^2
81=x^2+49
x^2=81-49
x^2=32
x= √32
x= 5.65685424949
Answer:
n = 195
Step-by-step explanation:
What sample size is necessary such that a 98% confidence interval for the mean, using σ = 3, has a width of pm±0.5?
We solve using Margin of error formula
= z × Standard deviation/√n
Margin of error = ± 0.5
Standard deviation = 3
n = ??
z = 2.326
Hence,
±0.5 = 2.326 × 3/√n
Cross Multiply
±0.5 × √n = 6.978
√n = 6.978/±0.5
√n = ±13.956
Square both sides
n = (±13.956)²
n = 194.769936
Approximately = 195 samples
44900 mgs converted to grams would equal 44.9 grams
