The relative frequency for the class with lower class limit 31 is 8.57%.

<h3>How to calculate the frequency?</h3>

It should be noted that the lowrr class frequency is 31 in this case.

= 3/35 × 100

= 8.57%

Therefore, the relative frequency for the class with lower class limit 31 is 8.57%.

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200
vova2212 [387]

Answer:

x = 200

Step-by-step explanation:

Given

\frac{1}{5} x - \frac{2}{3} y = 30 ← substitute y = 15 into the equation

\frac{1}{5} x - \frac{2}{3} × 15 = 30 , that is

\frac{1}{5} x - 10 = 30 ( add 10 to both sides )

\frac{1}{5} x = 40 ( multiply both sides by 5 to clear the fraction )

x = 200
