The following six integers are arranged from smallest to largest 1 , x , 3 , y , 14 , z
The mode is 1, the median is 5 and the mean is 7.
a. [1 mark] Find the value of x;
b. [2 marks] Find the value of y;
c. [2 marks] Find the value of z.

c.

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

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°
