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%
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.
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 = 
= 
= 
= 
= 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,
unit
= 11.52 unit on wire
and, Andy will spend,
unit
= 18.72 unit on wire.
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)
