Answer:
a. 54.05 Mpbs.
b. 2.745... standard deviations.
c. The z-score is 2.745....
d. The carrier's highest data speed is significantly high.
Step-by-step explanation:
a. The difference between the highest measured data speed and the mean is 72.6 - 18.55 = 54.05 Mbps.
b. The amount of standard deviations of 54.05 Mbps is equal to this value divided by the standard deviations, so we yield
standard deviations.
c. The z-score is equal to the difference between the mean and a data point in standard deviations, so the z-score is 2.745....
d. 2.745... is not between -2 and 2, so the carrier's highest data speed is not insignificant - so it's significantly high.
Answer:
answer is b
Step-by-step explanation:
I'm smart bro
<dpb because they’re vertical angles (they’re directly across from each other)
Answer:
3) 5
5) 1
Step-by-step explanation:
substitute the value of 9 for each 'x' in the expression
3) h(9) = 2/3(9) - 1
= 18/3 - 1
= 6-1 or 5
substitute the value of 5 for each 'x' in the expression
5) f(5) = -5² + 6(5) - 4
= -25 + 30 - 4
= 5-4 or 1
