Which statement is not true about the data?

A.
The range of the sales is 66 bars.

B.
The interquartile range of the data is 24 bars.

C.
The first quartile of the data is 24 bars.

D.
The third quartile of the data is 45 bars.

The statement that is not true about the data is statement D.

Step-by-step explanation:

The higher value is 78 and the lower value is 12. In order to find the range, we must subtract these two.

78 - 12 = 66

The range of the sales is 66 bars, so A is correct.

The upper quartile is 48 and the lower quartile is 24. To find the interquartile range, we have to subtract them.

48 - 24 = 24

The interquartile range of the data is 24, so B is correct.

The first quartile, or lower quartile, of the data is 24 bars, so C is correct aswell.

Lastly, the third quartile of the data is 48 bars, so D is not true, it is incorrect.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
