Answer: Maturation
Step-by-step explanation:Internal validity is a type of validity that establishes a cause and effect relationship,this type of validity tries to eliminate alternative explanation for a Discovery.
One of the threats to internal validity is MATURATION.
MATURATION is the type of threat occuring during experiment to prove a particular Discovery as shown by the question where the police officer shot and killed someone against the intention of the experiment.
The two consecutive integers are 2 and 3
<em><u>Solution:</u></em>
Let x and x + 1 are the two consecutive integers
Let "x" be the smallest integer
Let "x + 1" be the larger integer
<em><u>Given that, sum of 2 consecutive integers is one less than 3 times the smaller integer</u></em>
Therefore,
sum of 2 consecutive integers = one less than 3 times the smaller integer
sum of 2 consecutive integers = 3 times the smaller integer - 1
x + x + 1 = 3(x) - 1
2x + 1 = 3x - 1
3x - 2x = 1 + 1
x = 2
Thus the smaller integer = x = 2
Larger integer = x + 1 = 2 + 1 = 3
Thus the two consecutive integers are 2 and 3
Answer:
2550
Step-by-step explanation:
I'm assuming the interest is annual.
so this is breaking the 6000 into two parts, I am going to call them A and B. i will say A is invsted at 4% and B is invested at 6%
It then tells us the amount of interest gaied from B is $15 more than the interest gained from A. We basically use a system of equations.
A + B = 6000
.06B - .04A = 15
Let me know if you don't see how I got these equations. I will go ahead and solve.
A + B = 6000
Gonna solve for A so I can plug it into the other eqaution and solve for B, which is what the question is asking for. You can get both either way though.
A = 6000 - B
Plug this into the other equation.
.06B - .04A = 15
.06B - .04(6000 - B) = 15
.06B - 240 + .04B = 15
.1B = 255
B = 2550
this means A is 3450. You can check by seeing what theinterest is for each.
2550*.06 = 153
3450*.04 = 138
153 is 15 more than 138 so everything checks out.
Noticed how it forms a supplementary angle.
A supplmentary angle is basically two angles that added up to 180 degrees.
So we have:
64 + x = 180
Then we solve for "x", so "x" = 116.
Hope that makes sense :)
A brachisticrone is a curve of fastest decent. Which is a curve between two points along which a body can move under gravity in shorter amount of time compared to other curves.
