How do I solve 2x-3y=12 step by step?
anzhelika [568]

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

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 72.6 Mbp
Lapatulllka [165]

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 \frac{54.05}{19.69} = 2.745... 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.
