X≥8
So x has to be at the VERY LEAST 8, so it can be 8, that's what the line under the greater than sign equals, but it can't be less than 8 so you would need the greater than sign not the less than
Answer:
Step-by-step explanation:
If a lift will carry 8 people safely with an average mass of 75kg each we multiply to find the weight the lift can safely carry.
8 x 75kg = 600kg
If the average mass of the people is 100kg each, we divide to find the number of people it can carry. We know the lift can carry 600kg.
600kg/100kg = 6
So the lift can carry 6 people if their average mass is 100kg.
For this case, the first thing we must do is define a variable:
x: number of people that the minivan can transport safely.
We write now the inequality that represents the problem:
0 <= x <= 7
The solution is:
[0, 7]
Answer:
A number line that illustrates the capacity of the Nichols minivan as an inequality is:
option C
Answer:
C. Two-tailed paired t-test.
Step-by-step explanation:
Since Dr. Hernandez takes 30 samples from a contaminated lake and 30 fish from a pristine lake, he should use a two-tailed t-test.
Paired t-tests describe tests used to compare the means of two samples when each observation in one sample can be paired with an observation in the other sample. Dr. Hernandez can certainly pair the samples and observe the differences, so the answer is C. Two-tailed paired t-test.
Hope this helps!
