Answer:

m<4=40

Step-by-step explanation:

Supplementary angles form 180 degrees

m<3 is vertical to the 50 degree angle which is equal.

so. m<3=50

m<5=90

90+50=140

180-140=40

m<4=40

Answer:

D is not a supported statement

Step-by-step explanation:

Let take them one by one:

A: from table: 0.57; in statement: 0.5

0.57 > 0.5 so this is supported

B: from table: 0.2+0.16=0.36; in statement: 1/3=0.33,

0.36>0.33 so this is supported

C: 0.07 is the least, so this is supported

D: the table DOES NOT show number of students, but proportions. So statement '7 students' IS NOT supported

E: from table 0.20 overslept. 0.2 < 1/4=0.25, so this is supported
