The way to find the difference between 5y - 3 you have to first do the inverse operation of multiplication which is division.
5y - 3
__ __
5 5
y - 0.6
Answer:
A. Randomized experiment.
Seee explanation below.
Step-by-step explanation:
Previous concepts
In a Randomized experiment the results can be use to establish causal inferences about means of control. and present two important characteristics:
a) "the independent or explanatory variable is controlled by direct manipulation.
b) "All other sources of variability are controlled by chance".
An observational study is an empirical but is nonexperimental investigation in order to see the effects caused by an specific treatment.
Solution to the problem
For this case we want to determine the effect of adhesive brands on the bonding of veneer to cabinets.
The experiment is conducted with 6 different groups defined with different adhesive and all the groups are the same except by the type of brand for the adhesive used.
So on this case we see that the variable of interest is controlled with direct manipulation with the creation of the 6 groups. And we have that all the the others sources of variability are controlled by chance since all the groups are identical except by the brand type.
So for this case the correct answer would be:
A. Randomized experiment.
The seats must be arranged in a 38 by 39 arrangement to have the minimum amount of seats used.
You can find this by finding the square root of 1450, which is 38.0788655293.
Answer:
Δx= 184.12 ft
Step-by-step explanation:
The equation you need to use is velocity as a function of displacement.
v = the speed at which the car is travelling,
and
v_o is the original speed (in this case zero).
The change in x (displacement) is how far the car travels. You will be solving for a (acceleration).
solving we get
a= 12.19
now put this acceleration value into the second case when v= 67mi/h
⇒Δx= 184.12 ft
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.
