Since the number ranges between 3 and 10, an equation can't be made because the number is always unknown or can be different every time
Answer:
The answer is below
Step-by-step explanation:
Different countries have different metric system of measurement, but the metric system of measurement accepted all over the world is the international system of unit (SI unit)
1 quintal = 220.462 lbs and 1 bushel of corn = 56 lbs.
151 q/ha = (151 × 220.462) lbs/ha = 33289.762 lbs/ha
But 1 hectare = 2.471 acre, hence:
33289.762 lbs/ha = 
Since 1 bushel of corn = 56 lbs, hence:
= 240.6 bu/ac
For a Margin of Error: +/- 1 bu/ac, the bushels per acre = (239.6 bu/ac, 241.6 bu/ac)
Answer:
unbiased sample values
Step-by-step explanation:
Unbiased sampling involves eliminating any form of bias in the method of selection of participants in a study in order to draw a conclusion about the population.
Paul had introduced bias in the sampling that out to look at the number of hours a day the typical student studies by introducing the variable of studying during the final exam period.
Most likely all student will study during the final exam period. This will not truly represent the study pattern of the sample population and equal chance of selection of study hours of the students. Hence paul had violated the requirement of unbiased sample values for probability sampling by not doing a random selection or systematic random selection
Answer:
x=−15+√10 or x=−15−√10
Step-by-step explanation:
Let's solve your equation step-by-step.
(x+15)2−10=0
Step 1: Simplify both sides of the equation.
x2+30x+215=0
For this equation: a=1, b=30, c=215
1x2+30x+215=0
Step 2: Use quadratic formula with a=1, b=30, c=215.
x=−b±√b2−4ac/2a
x=−(30)±√(30)2−4(1)(215)/2(1)
x=−30±√40/2
x=−15+√10 or x=−15−√10
