X+y=6 --> Equation 1
x-y=8 --> Equation 2
Equation 1 - Equation 2 =
2y =-2
y = -1
x+y = 6 --> Plug y value into equation
x + (-1) = 6
x-1 = 6
x = 7
y = -1, x = 7
Answer:
"You" are 25.
Step-by-step explanation:
Let's do a check list with the number 25.
Multiple of 5? Yup.
When you add 3 to 25, is it divisible by 7? Indeed it is. This is because 25 + 3 is 28, which can be divided by 7. (28 divided by 7 is 4, by the way.)
Is 25 between 14 and 32? Yes.
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%

Answer:
The first thing you need to do is, have a square whose area is 11² = 121 square inches. Then we are going to multiply the radius by π which is 3.14 the area of the circle with the radius 4 is equal to 3.14 × 4² = 3.14 × 16 = 50.24, you need to divide the calculated radius times π (3.14) you can get the answer and you need to round your answer to the nearest hundredth probability that the dart will hit within the circle is equal to 50.24 ÷ 121 = 0.4152066116 which is rounded to 0.04152 or 41.52% this assumes the dart will always hit the square at least.
