z+c+t = 48, 7 zucchini, 14 Cucumbers, 22 tomatoes
In this equation, we will change all plants in terms of zucchini
zuccini=z (base term)
cucumbers =2z (two times the number of zucchini
tomatoes = 2z+8 (eight more than cucumbers)
z+c+t= 43
z+2z+2z+8=43 combine like terms
5z+8=43 subtract both sides by 8
5z=35 divide by 5
z=7
Plug in values for z to solve for c and t
cucumbers = 2(7) = 14
Tomatoes = 2(7)+8 = 22

To answer this question you can create an equation in terms of the number of zucchini that were planted.  Each other plant gives information that can relate to the number of zucchini plants.

# of cucumbers +   # of tomatoes  + # of zucchini
       2z              +           2z + 8     +       z =  43 
       5z + 8 = 43
             -8     -8
       <u>5z</u>      = <u>35</u>
       5           5 
       z = 7 plants

There were 7 zucchini plants, 14 (2 x 7) cucumber plants, and 22 (2 x 7 + 8) tomato plants.

What is x+y=10;y=x+10
Alenkasestr [34]

[ Answer ]

\boxed{\bold{X \ = \ 0, \ Y \ = \ 10}}

[ Explanation ]

  • System Of Equations \bold{\left \{ {X \ + \ Y \ = \ 10} \atop {Y \ + \ X \ = \ 10}} \right.}

-----------------------------------

  • [Substitute] Y = X + 10

\bold{\begin{bmatrix}x+x+10=10\end{bmatrix}}

  • Isolate x for x + x + 10 = 10: x = 0

For y = 10

Substitute x = 0

Y = 0 + 10

0 + 10 = 10

y = 10

  • Solutions

X = 0

Y = 10

\boxed{\bold{[] \ Eclipsed \ []}}

At a production process, the produced items are tested for defects. A defective unit is classified as such with probability 0.9,
Snezhnost [94]

Answer:

We use Baye's theorem:  P(A)P(B|A) = P(B)P(A|B)

with (A) being defective and

(B) marked as defective

we have to find P(B) = P(A).P(B|A) + P(¬A)P(B|¬A). .......eq(2)

Since  P(A) = 0.1 and P(B|A)=0.9,

P(¬A) = 1 - P(A) = 1 - 0.1 = 0.9

and

P(B|A¬) = 1 - P(¬B|¬A) = 1 - 0.85 = 0.15

put these values in eq(2)

P(B) = (0.1 × 0.9) + (0.9 × 0.15)

       = 0.225 put this in eq(1) and solve for P(B)

P(B) = 0.4
