1 answer:
The solution to the given system of equation is -7 and 7
<h3>Solving linear equation</h3>Linear equations are equation that has a leading degree of 1. Given the expression
4x^2 = 196
Divide both sides by 4
4x^2/4 = 196/4
x^2 = 49
Take the square root of both sides
√x^2 = √49
x = √49
x = ±7
Hence the solution to the given system of equation is -7 and 7

Answer:
68% Confidence interval = [4.5752, 4.5848]
95% Confidence interval = [4.5688, 4.5918]
Step-by-step explanation:
Sample mean (X) = 4.580
Sample Standard Deviation (S) = 0.01065
Sample size (n) = 6
for alpha/2 0.84 = 1.1037
for alpha/2 0.975 = 2.5706
68% Confidence interval = = [4.5752, 4.5848]
95% Confidence interval = = [4.5688, 4.5918]
