Step-by-step explanation:
125 + 30 + 25 + b is equal to 180 degree 19 + y equal to 180 degree equal to 180 - 190 equal to - -10
I have mercy:
8x and 9x+5 (the angles) form a right angle so 8x+9x+5=90 which means x is 5 and plugging it back into the angles 8x we get 40 sinceBHR and angle 8x are vertical angles they are equal to each other and so it's equal to 40
Starting point 27(3/8) - loss 2(1/2) = 24.875 which is the closing value
![\bf \begin{cases} f(x)=\cfrac{2}{x}\\[1em] g(x)=x^2+9 \end{cases}~\hspace{5em}f(~~g(x)~~)=\cfrac{2}{g(x)}\implies f(~~g(x)~~)=\cfrac{2}{x^2+9}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Bcases%7D%20f%28x%29%3D%5Ccfrac%7B2%7D%7Bx%7D%5C%5C%5B1em%5D%20g%28x%29%3Dx%5E2%2B9%20%5Cend%7Bcases%7D~%5Chspace%7B5em%7Df%28~~g%28x%29~~%29%3D%5Ccfrac%7B2%7D%7Bg%28x%29%7D%5Cimplies%20f%28~~g%28x%29~~%29%3D%5Ccfrac%7B2%7D%7Bx%5E2%2B9%7D)
that's one combination for f(x) and g(x), off many combinations.
Answer:
1/10
Step-by-step explanation:
P( 1st out of ink) = out of ink/total
=2/5
Then we have 4 pens left, 1 out of ink
P( 2nd pen out of ink) = out of ink/total
=1/4
P(2 pens out of ink) =P( 1st out of ink) * P( 2nd pen out of ink)
= 2/5* 1/4
=1/10
