The sum of all cars will be = 70 + 30 + 50 + 80 + 20 = 250
So,
<span>the probability that’s the nexts car to drive by will be red = (red cars)/(total cars)
= 50 / 250 = 0.2
</span>
the probability that’s the nexts car to drive by will be <span>blue = (</span><span>blue cars)/(total cars) = 70 / 250 = 0.28
then
</span>
<span>the probability that’s the nexts car to drive by will be red or blue
= 0.2 + 0.28 = 0.48 </span>
Multiply 3x +y =23 by -4
x+4y=4
-12x+(-4y)=-92
Add together
-11x = -88
x = 8
Plug x in to find y.
8 + 4y = 4
Subtract 8 from each sides
4y = -4
Divide by 4
y = -1
So the answer is x =8, y= -1
I hope that helps!
Answer:
C
Step-by-step explanation:
The equation is y=mx+b so you're correct :)
Well if it is -20 then A but if it was just 20 it would be C all you have to do is divide

Answer:
125.6 cm²
Step-by-step explanation:
The relevant area formula is ...
Area = (1/2)ac·sin(B)
Area = (1/2)(13 cm)(21 cm)·sin(67°) ≈ 125.6 cm²
