We know that there is a total of 900 cells, and 37 of the samples 60 are red. 900/60 is our unit rate of 15. 37 times 15 is 555. We will see 555 red blood cells in all of the cells.
555 is our answer.
Please forgive any typeos because I did this on my phone.
Because thee dimensions of ΔRAH is twice as large as corresponding dimensions of ΔEAC,
|RA|=2|EA|=2*3.5=7
|AH|=2|AC|=2*6=12
So, we have that 2 corresponding sides are in proportion and angle between them =90⁰, so the angle between them are congruent,
we can use SAS to prove that these triangles are similar.
Answer:
Step-by-step explanation:
The easiest way to determine the answer to your question is to evaluate the
discriminant
For a quadratic in the form:
y
=
a
x
2
+
b
x
+
c
the
discriminant
) is equal to
b
2
−
4
a
c
For your example
4
x
2
+
8
x
+
3
=
0
The
discriminant
is
Δ
=

It would be the median of the data set
