Hey there! :D
All you need to remember is this formula:
A= 1/2*base*height <== this is for a triangle's area
Base= 4 Height=3
1/2*3*4
1/2*12
6 square meters. <== the answer
I hope this helps!

Answer:
just function A
A is, for every 2x (2 steps) the value of y increased linearly by 2.5
B isn't, for every 10x (10 steps), the increase of y varies
X -2y = 5
X -2y +2y = 5 +2y
X = 5 + 2y
Plug this into first formula.
2X + 3y = -4
2 (5 + 2y) +3y = -4
10 + 4y +3y = -4
10 + 7y = -4
10 -10 + 7y = -4 -10
7y = -14
7y/7 = -14/7
y = -2
Now plug Y back into <span>2x + 3y = -4
2x + 3(-2) = -4
2x -6 = -4
2x -6 +6 = -4 +6
2x = 2
</span>2x/2 = 2/2
x = 1
Check by plugging X & y values in either formula.
2(1) + 3(-2) = -4
2 -6 = -4
-4 = -4

Answer with Step-by-step explanation:
Yes No No Opinion
Male 92 48 47
Female 78 63 49
Given that a randomly selected response was "No Opinion"
what is the probability that it came from a female?
It is a problem of conditional probability in which
A: response came from a female
B: Response is "No Opinion"
Total number of no opinions=49+47=96
Total outcomes=92+78+48+63+47+49=377
P(B)=96/377
A∩B: No opinion from a female
P(A∩B)=49/377
P(A|B)=P(A∩B)/P(B) (by Baye's theorem)
=![\dfrac{\dfrac{49}{377}}{\dfrac{96}{377}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cdfrac%7B49%7D%7B377%7D%7D%7B%5Cdfrac%7B96%7D%7B377%7D%7D)
= 49/96
= 0.51
Hence, given that a randomly selected response was "No Opinion",the probability that it came from a female is:
0.51
