You would have a grade of an 88%
Answer: Yes, he makes a reasonable inference.
Step-by-step explanation:
Since we have given that
Number of students = 60
Number of chosen science students = 12
Percentage of students who chose science is given by
12/60 x 100
= 1/5 x 100
= 20%
Since Mr. Rodriguez used the data to draw the inference that about 20% of middle school students prefer to read science fiction.
So yes, he makes a reasonable inference.
Answer:
Ok, to find MAD, you have to add up all of the decimals in the set, and then divide by how much decimals there are in the set.
Adding them all up...
The final result of the adding is 56.7
Now, we have to divide by how much decimals.
We now have. 56.7 / 6
Do the division.
56.7 / 6 ===> 9.45
No need to round, the final answer is 9.4
The 4 is underlined right? if so then the answer would be c
Answer:
r = 6 mph and f = 11 mph
Step-by-step explanation:
Representations:
1) speed of faster cyclist: f = r + 5
2) speed of slower cyclist: r
Distances covered:
(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)
Then 5r + 25 + 5r = 55, or, after reducing this equation:
r + 5 + r = 11, or
2r = 6
Then r = 6 mph and f = 11 mph
