Let x be the score of the 3rd quiz,, then the average score will be:
(83+91+x)/3, which = (174+x)/3. but this average should be greater or equal to 85 and smaller or equal to 90:
85 ≤ (174+x)/3 ≤ 90
1st multiply all terms with 3 → 255 ≤(174+x) ≤ 270
2nd subtract 173 from all terms → 255-174 ≤174-174+x ≤270-174
81 ≤ x ≤ 96
Answer:
1700 trees/acre
Step-by-step explanation:
All you must do is divide 15300÷3 which is 1700.
The frequency of the second class is 6.
Since the class width is 6 and the lower limit of the first class is 50, this means the first class goes from 50-55. This would put the second class at 56-61. There are 6 data points in this set that would go in the second class.
Answer:
the answer is d.
Step-by-step explanation:
D} the independent variable is cows, and the dependent variable is milk.
The independent variable is cows, and the dependent variable is milk.
The value of the independent variable, often denoted by x, does not depend on the value of another variable. The value of the dependent variable, often denoted by y, depends on the value of the independent variable.
