Laila is 14 years older than tom. Laila is 5 years younger than Dan. Altogether they have a combined age of 51. How old are they
notka56 [123]
Laila=l
Tom=t
Dan=d

l=t+14
l=d-5
l+t+d=51

In terms of l:
d=l+5
t=l-14

So:
l+l+5+l-14=51
3l+5-14=51
3l-9=51
3l=60
l=20
d=25
t=6

Hope this helps :)

Which statement must be true according to the dot plot?
expeople1 [14]

*see attachment for the dot plot being referred to

Answer:

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.
