x= -3/8

here's how you solve it!

first distribute the -2/3 into the parentheses and you'll get:

4-8/3x+6=11

Then add 4 and 6 together

10-8/3x=11

Then multiply the equation by 3

30-8x=33

Then move the constant to the other side and change the sign

-8x=33-30

Subtract 30 from 33

-8x=3

Then divide both sides by -8

x=-3/8

Then you are left with your answer:

x= -3/8

Hope this helps! :3

Simplify both sides of the equation.

4 −  2/3  (4x − 9) = 11

4 +  −8/3  x + 6 = 11

Distribute

(−8/3  x) + (4 + 6) = 11

Combine Like Terms

−8/3x+10=11

Subtract 10 from both sides.

−8/3x + 10 − 10 = 11 − 10

−8/3

x = 1  

Multiply both sides by 3/(-8).

(3/−8)*(−8/3  x) = (3/−8)*(1)

x =  −3/8

timama [110]

Answer:

D.​No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

Step-by-step explanation:

(a) Range is the difference between the smallest and largest observation.

Here Smallest observation = 0.63

and Largest observation = 1.48

⇒ Range = 0.85

(b) Standard Deviation is calculate by,

Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }

where, \bar{x} is mean of the observation.

Here, Mean = 0.988

⇒ Standard Deviation = 0.313

(c) Variance is the square of Standard deviation.

Thus, Variance = (Standard Deviation)² = 0.098

(d) Here last option(D) is true i.e. ​No, because some models of cell phones will have a larger market share than others. Measures from different models should be weighted according to their size in the population.

Answer:

Percent increase is 17.6%

We still have to pay 7.50 with the coupon

Step-by-step explanation:

Percent increase = (new- original)/original *100%

                             = (10-8.5)/8.5 * 100%

                             = 1.5/8.5 * 100%

                             = 17.6470588%

Round to the nearest tenth

                                 17.6%

This is an increase since the cost went up.

If we have 25% off, we still have to pay (100%-25%) = 75%

10 *.75 = 7.50

We still have to pay 7.50 with the coupon
