A C and F those would be the correct answers girlie
Answer:
B could be used to show the formula to describe the sentence
-4n*(n^2 -6n +3)
= (-4n)*n^2 +(-4n)*(-6n) +(-4n)*(3)
= -4n^3 +24n^2 -12n . . . . . . . . . . . . corresponds to selection B
Note that the signs alternate. For the first question the signs of the answer are the reverse of those of the original trinomial.
For the second question, multiplying by -n changes the signs back to those of the original trinomial. Only one answer has the signs correct, selection A.
Answer:
AE = 43.2 units
Step-by-step explanation:
As per the given question image, it can be seen that in the 
1. 
2. 
is common to both the triangles.
3. Two angles are common, so the third angle 
is also equal to 
.
All the three angles in the 
are equal to each other, hence the triangles are similar.
As per the property of similar triangles, the ratio of their sides will be equal.
AB : AC = AE : AD
AC = 88 units
BC = 55 units
AB = AC - AB = 33 units
Let side AE = 
units
Side AD = AE + ED
So, AD = 
Using the ratio:
So, AE = 43.2 units
There are several information's already given in the question. based on those information's, the answer can be easily deduced.
a. It is already given that 1% are defective. It is required to find the number that is needed to be checked to get 5 defective products.
Then
1% of X = 5
0.01X = 5
x = 5/0.01
= 500
b. <span>σ = square root [(<span><span><span><span>n^2</span>−1)/</span>12]
= square root [(250000 - 1)/12]
= square root [249999/12]
= square root (20833.25)
= 144.34
= 144
I hope the procedure is clear enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.</span></span></span>
