At Lawson Middle School, Mr. Hernandez asked 90 randomly selected students from each grade level for their favorite subject, and

28 chose social studies as their favorite. He used this data to draw the inference that out of the 250 middle school students, about 20% prefer social studies. Did he make a reasonable inference?

How are 12 fl oz equivalent to 335 ml
Mazyrski [523]
The question asks us to find that 12 fl oz is equivalent to 335 ml. Then we have to either convert the milliliter to oz or vice-verse. In this case we will convert 12 fl oz to milleter and check if it comes to 335 ml.
Now we already know that
1 oz = 29.57 ml
Then
12 oz = (29.57 * 12) ml
          = 354.84 ml
         = 355 ml
So we see that 12 oz is not equal to 335 ml but it is almost equivalent to 335 ml.

Please help please please please!!!!!
Nana76 [90]

Step-by-step explanation:

mean of cheese = 99+8+10/3 = 117/3 = 39

mean of butter = 41+16+0/3 = 57/3 = 19

mean of non fat dairy milk = 255+8+15/3 = 278/3 = 92.6~93

median of cheese 8, 10, 99 median is 10

median of butter 0, 16, 41 median is 16

nonfat dairy milk 8, 15, 255 median is 15

range of cheese 99-10 = 88

range of butter 41-16 = 25

range of nonfat dairy milk = 255-8 = 247

3^17-3^15+3^13 So you factor out 3^13

=3^13(3^4-3^2+1)

3^4-3^2+1=73

3^13*73
