Answer:
The correct answer is: 3. QR ∦ ST 4. QR ║ ST
Step-by-step explanation:
If the PST and PQR triangles are similar, then the corresponding sides are proportional. We will check that:
PS : PQ = PT : PR ⇔ PS / PQ = PT / PR = k
3.
10/4 = 8/3 => 5/2 = 8/3
When we multiply the both fractions to get same denominators we get
15/6 ≠ 16/6
the corresponding sides are not proportional and triangles PST and PQR are not similar and QR ∦ ST => QR is not parallel to ST
4. 27/22 = 43.2/35.2 = 1.2272727.... = 1.2(27)
the corresponding sides are proportional and triangles PST and PQR are similar and QR ║ ST => QR is parallel to ST
God with you!!!
Answer:
x – 3y = 9 ⇔ y =
the line parallel is y' =
y' = passes through (3, -1) --> -1 = × 3 + b --> b = -2
⇒ y' =
c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.
First equation: -8x+7y=-17
Second equation: y=2x+1
Take the value of y from the second equation, as y is already isolated, and plug it in for y in the first equation. Simplify and solve for x.
-8x+7(2x+1)=-17
-8x+14x+7=-17
6x+7=-17
6x=-24
x=-4
Take the value of x we just found and plug it into the first equation. Solve for y.
-8(-4)+7y=-17
32+7y=-17
7y=-49
y=-7
Hope this helps!! :)
Answer:
The false statement is "it can be used for one variables at a time"
Step-by-step explanation:
Given:
Simulation for NPV.
To Find :
Which statements is not correct .
Solution;
In simulation NPVs, Net present values.
<em>In Excel the simulation called as monte carlo simulation</em>
So it consists of variables like mean ,standard deviation, variance etc.
In simulation it develops the graphs .
It consists of formula for probability calculation
So it has probability distribution function.
Ultimately, It will develop the output values for input variables.
Hence The false statement will be that" it can only be used for one variable at a time"
