C < 5
there will be an open circle on 5....it is open because there is no equal sign in the problem.....the shading will be to the left....because less then is shaded to the left
14.94 cm ( to 2 dec. places )
We require the sum totals of the 2 groups before calculating the mean of all 14
using mean = 
Children's sum
12.6 = 
( cross-multiply )
sum = 6 × 12.6 = 75.6
Adult's sum
16.7 = 
( cross- multiply )
sum = 8 × 16.7 = 133.6
Total sum of all 14 = 75.6 + 133.6 = 209.2
mean = 
= 14.94 cm
Answer:
4x+y=34
Step-by-step explanation:
Linear equations can be written in 3 forms:
slope-intercept form
standard form
point-slope form
standard form's formula is ax+by=c,
now sub in 34 for c and 4 for a
4x+by=34
we can put in 1 for b since there is no other integers
4x+y=34
2 1/4 you divide 4 into nine and minus the remainder
