X = 3 my answer needs to be 20 characters
Answer:
45,78%
Step-by-step explanation:
42 + 67 = 109
109 x 42 / 100 = 45,78 %
The z-value that corresponds to a two-tailed 95% confidence interval is z = +/- 1.96. Then the bounds of the confidence interval can be determined as:
Lower bound = mean - z*SD/sqrt(n) = 20 - 1.96*2/sqrt(100) = 20 - 0.12 = 19.88 hours
Upper bound = mean + z*SD/sqrt(n) = 20 + 1.96*2/sqrt(100) = 20 + 0.12 = 20.12 hours
So the first choice is the correct answer: 19.88-20.12 hours
2/3-1/4=5/12
You could make the denominators common by finding the GCF
The GCF of 4 and 3 is 12
This means that 8/12-3/12 which would give you 5/12.

Answer: y = 17x
Step-by-step explanation:
Note that the equation that will be used is: y = mx + b,in which m = slope and b = y-intercept.
Solve for b:
0 = 17(0) + b
Simplify:
0 = 0 + b
b = 0
Equation: y = 17(x)
