Answer:

p = $\frac{16}{3}$

Step-by-step explanation:

Given

$\frac{p}{20}$ = $\frac{p-4}{5}$ ( cross- multiply )

20(p - 4) = 5p ← distribute left side

20p - 80 = 5p ( subtract 5p from both sides )

15p - 80 = 0 ( add 80 to both sides )

15p = 80 ( divide both sides by 15 )

p = $\frac{80}{15}$ = $\frac{16}{3}$

If the mean heights of three groups of students consisting of 20,16 and 14 students are 167m, 150m and 1.40m respectively find t

Aleonysh [2.5K]

Answer:

1.54 m

Step-by-step explanation:

Given information:

Three groups of students

20 students with a height of 1.67 m
16 students with a height of 1.50 m
14 students with a height of 1.40 m

⇒ Total number of students = 20 + 16 + 14 = 50

To find the mean height of all the students, divide the sum of all the students' heights by the total number of students:

$\begin{aligned}\implies \sf mean\:height & =\dfrac{(20 \times 1.67)+(16 \times 1.50)+(14 \times 1.40)}{50}\\\\ & = \dfrac{33.4+24+19.6}{50}\\\\ & = \dfrac{77}{50}\\\\ & = 1.54\:\: \sf m\end{aligned}$

Therefore, the mean height of all the students is 1.54 m
