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%

Mini muffins cost $3:00 per dozen Andre says I have $2:00 so I can afford 8 muffins Elena says I want to get 16 muffins so I’ll
jasenka [17]

Answer:

I agree with both.

Step-by-step explanation:

If it's $3 per dozen that would be $0.25 per muffin because

3 ÷ 12 = 0.25

And if Andre has $2 than he can only afford 8 muffins because

0.25 x 8 = 2

And if Elena wants 16 muffins

16 x 0.25 = 4

So she will have to pay $4.

Hope this makes sense and helps!

Answer:

$29000 with a margin of error of $5000

Step-by-step explanation:

We have that the midpoint between the given values ​​is

(X1+X2) / 2 = ($34000+$24000)/2 = $29000

We have that the midpoint between the given values ​​would be

(X2-X1)/2=($34000-$24000)/2=$10000/2=$5000

So I can write that approach as $29000 with a margin of error of $5000

Done
