Answer:
Step-by-step explanation: •Subtract 2x from both sides of the equation.
-3y = 12 - 2x
•Divide each term by -3y = 12 - 2x by -3.
-3y/-3 = 12/-3 + -2x/-3
•Cancel the common factor of -3.
12/-3 + -2x/-3
•Divide y by 1.
y = 12/-3 + -2x/-3
•Simplify each term.
•Divide 12 by -3.
y = -4 + -2x/-3
•Dividing two negatives values results in a positive value.
y = -4 + 2x/3
Can you post the provable question
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.
