Answer: 0.4127
Step-by-step explanation:
The probability formula to find p(F/E):
p(F/E)= N(E n F) / N(E)
p(F/E)= 260 / 630
p(F/E) = 0.4127
Answer: +80°C or -20°C
Step-by-step explanation:
This is the answer because if you add 80 then it will equal 100°C and freeze and if 20°C is taken away it will equal 0°C and freeze.
Answer:
×-10×+21=0
FACTORIZATION of splitting the middle term
There is a mistake in your writing
:The similar triangles should be ABE (& not ABD as you stated) & ACD
If so, we can write the following proportion:
AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8
3x/10-2 = x/5+2
+2 +2
3x/10 = x/5+4
x10 x10
3x = x(5 x 4)
-x -x
2x = 20
/2 /2
x=10
