Answer:

18.4%

Step-by-step explanation:

The formula for rel. freq. is:

Relative Frequency = Class Frequency/n

Where

Class Frequency will be the number of students in the class we are interested in (in 35-38, the number of students is 9)

n is the total number of students [which is 6+7+8+9+10+9= 49]

Putting into formula we get:

Relative Frequency = 9/49 = 0.1837

To get percentage, we need to multiply by 100:

0.1837 * 100 = 18.37%

Rounded to 1 decimal place, that is 18.4%

Solve for x I need help on this question

AlexFokin [52]

Answer:

$x\approx7.8$

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

$sin(\theta)=\frac{opposite}{hypotenuse}$

$sin(23^\circ)=\frac{x}{20}$

$20sin(23^\circ)=x$

$x=20sin(23^\circ)$

$x\approx7.8$

Therefore, the length of the opposite side is about 7.8 units
