Which statement must be true according to the dot plot? The number of text messages that Reza sent each day so
far in this billing cycle is shown on the dot plot.
Text Messages Per Day
O The data is symmetric and shows that he typically sent
about 6 to 8 text messages per day.
o The data is symmetric and shows that he sent 11 or 12
texts with the same frequency that he sent 1 or 2 texts.
O The data is skewed and shows that he typically sent
about 6 to 8 text messages per day.
O The data is skewed and shows that he sent 11 or 12
texts with the same frequency that he sent 1 or 2 texts.

The data is symmetric and shows that he typically sent about 6 to 8 text messages per day

Step-by-step explanation:

The distribution of the data set on a dot plot can be said to be symmetric when most of the data points in the data are located or are concentrated at the center of the dot plot.

As we can observe from the given dot plot in the attachment, it shows that 6 to 8 text messages per day have more frequencies and are just right at the center of the dot plot. This shows the data is symmetric.

This also shows that Reza dents averagely 6 - 8 text messages per day. Reza can be said to have typically sent 6 - 8 text messages per day.

The rest statements about the dot plot are untrue.

80 minutes ; $25

Step-by-step explanation:

Let x = number of minutes

Plan A :

17 + 0.1x - - - (1)

PLAN B :

13 + 0.15x - - - (2)

Both plans will cost the same when ;

17 + 0.1x = 13 + 0.15x

Solve for X

0.1x - 0.15x = 13 - 17

-0.05x = - 4

divide both sides by - 0.05

-0.05x / - 0.05 = - 4 / - 0.05

x = 80 minutes

Amount :

17 + 0.1(80) = 17 + 8 = $25
