Answer:
the last option bc 90÷2 is 45 so, we consider as *special*
So first we need to find approximately the number of total students.
Rock I would say is about 200 people. Country, 100, Rap, 255, Classical, 64 as said before, and Blues, 80.
So if we add these all up we can find the total students.
200 + 100 + 255 + 64 + 80
699
Now the relative frequency is how many times something appears in a group.
Classical appears 64 times in about 700 people.
So, 64/700, is closest to the 0.9 selection.
Answer:
2 Kg and 2.5Kg.
Step-by-step explanation:
Total number of parts = 4 + 5 = 9.
So the required quantities are 4*4.5 / 9 and 5*4.5/9
= 2 and 2.5.
First you need to find how many grams is 1 ounce. 1o z.is 28.35 g, then you need to multiply 28.35 g by 5 which is 141.75. you need to round it to the nearest hundred so it is about 142 grams.
the key here would be
1 oz. = 28.35g or 1 oz. = 28 g
1.) the y-intercept would be 4.95
