Answer: See below

Step-by-step explanation:

<u>Let A represent</u> an adult who visited a therapist

<u>Let B represent</u> an adult who used a non-prescription antidepressant

<u>Given:</u>
P(A) = 0.28 P

P (B) = 0.43

P(A Intersection B) = 0.22

a) P(B ∩ A) = P (B ∩ A) / P(A) = 0.22/0.27

P(B | A) = 0.79 or 79%

b)  P(A ∩ B) = P (A ∩ B) / P(B) = 0.22/0.4.3

P(A | B) = 0.51 or 51%

1/2x3+1/4x2 =<br> i need to know please
FrozenT [24]
In complex calculations like this,  the precedence goes like this

B = Brackets
O = Of (or Exponent)
D = Division
M = Multiplication
A = Addition
S = Substraction

So, in your formula, it will go like this

1/2x3+1/4x2
= 0.5 x 3 + 0.25 x 2
= 1.5 + 0.5
= 2

Hope this helps.

Emily and Andy each go to a hardware store to buy wire.The table shows the relationship between the cost and the length of wire.
Lady_Fox [76]

Answer:

So, Emily will spend,  11.52 unit on wire

and, Andy will spend  18.72 unit on wire.

Step-by-step explanation:

Cost of wire is = \frac {4.80}{120}

                       =  \frac {5.40}{135}

                       = \frac {6.00}{150}

                       = \frac {7.00}{175}  

                        = 0.04 unit/inch

We know that,

 12 inch = 1 foot    and

  1 yard = 3 foot    [Note that unit of a quantity always denoted singular].

So, Emily will spend,

  24 \times 12 \times 0.04 unit

 = 11.52 unit on wire

and, Andy will spend,

  13 \times 3 \times 12 \times 0.04 unit

 = 18.72 unit on wire.

MatroZZZ [7]

Answer:

2sqrt(2)

Step-by-step explanation:

5x^2 - 40 = 0

=> 5x^2 = 40

=> x^2 = 40/5 = 8

=> x = sqrt(8) = sqrt(4 x 2) = 2sqrt(2)
