F(x) = - 55x + 330
The domain is the set of possible input-values, i.e. x-values.
You know that f(x) cannot bebigger than 330 not lower than zero, then construct the inequality:
0 ≤ f(x) ≤ 330
0 ≤ - 55x + 330 ≤ 330
Multilply by - 1 and change the inequality signs:
0 ≥ 55x - 330 ≥ -330
Add 330 to all the members
330 ≥ 55x ≥ 0
Divide by 55
6 ≥ x ≥ 0 => 0 ≤ x ≤ 6
The the possible x-values (practical domain) is all the real numbers between 0 and 6 inclusive.
Answer:
736 N
Step-by-step explanation:
Area of the rectangular tile=length*breadth
=1.6*2.3 sq. metres
=3.68 sq . metres
Given, Maximum pressure sustainable by the tile=200N/sq.metres
Thus, the maximum force that can safely be applied to the tile=Pressure*Area
=200*3.68 N
=736 N
Answer:
Step-by-step explanation:
we have
<em>Find the amount of money that each girl spent</em>
For t= 2 hours
<em>Find the amount of money that they spend together</em>
Multiply by 2 the amount of money that each girl spent
When using ANOVA procedures, the research hypothesis is: there is no significance difference within the mean values of the groups.
<h3>What is a Research Hypothesis in ANOVA Procedure?</h3>
ANOVA procedure compares the mean values of different groups that are administered with treatments. The research hypothesis, such as the null hypothesis would be stated as: no significance difference in the mean values within the groups.
Thus, we can conclude that the research hypothesis when using the ANOVA procedures can be stated as a null hypothesis, which states that: there is no significance difference within the mean values of the groups.
