Answer: The 95% confidence interval is approximately (55.57, 58.43)
======================================================
Explanation:
At 95% confidence, the z critical value is about z = 1.960 which you find using a table or a calculator.
The sample size is n = 17
The sample mean is xbar = 57
The population standard deviation is sigma = 3
The lower bound of the confidence interval is
L = xbar - z*sigma/sqrt(n)
L = 57 - 1.960*3/sqrt(17)
L = 55.5738905247863
L = 55.57
The upper bound is
U = xbar + z*sigma/sqrt(n)
U = 57 + 1.960*3/sqrt(17)
U = 58.4261094752137
U = 58.43
Therefore the confidence interval (L, U) turns into (55.57, 58.43) which is approximate.

Answer:
<h2><u><em>
16 cm </em></u></h2>
Step-by-step explanation:
The volume of a cube can be found using the equation V=s^3 where s represents the length of the sides of the cube. if a cube has volume 4096 cubic centimeters, what is the length of each side of the cube?
you use the inverse formula
s = ∛V
s = ∛4096
s = 16 cm
-------------------------
check
16 × 16 × 16 = 4096 cm³
The answer is good
The equation given is in slope-intercept form. This is the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -4 and the y-intercept is 2. The answer is A.
