Answer:
0,250
Step-by-step explanation:
The probability that you looking for is sum of probability of getting someone in the 18-27age (74 persones) and probability to getting someone who refused (36 and 19 persones) - probability of getting some of 18-27 age who refused (36 persons).
The probability is:
P(a or b)= p(a)+p(b)-p(a&b)=74/371+(36+19)/371-36/371=0,199+0,148-0,097=0,250
Dy/dx = y/(x^2)
dy/y = dx/(x^2)
int[dy/y] = int[dx/(x^2)] ... apply integral to both sides
ln(|y|) = (-1/x) + C
|y| = e^{(-1/x) + C}
|y| = e^C*e^(-1/x)
|y| = C*e^(-1/x)
y = C*e^(-1/x)
So you have the correct answer. Nice job.
------------------------------------------------
Check:
y = C*e^(-1/x)
dy/dx = d/dx[C*e^(-1/x)]
dy/dx = d/dx[-1/x]*C*e^(-1/x)
dy/dx = (1/(x^2))*C*e^(-1/x)
is the expression for the left hand side (LHS)
y/(x^2) = [C*e^(-1/x)]/(x^2)
y/(x^2) = (1/(x^2))*C*e^(-1/x)
is the expression for the right hand side (RHS)
Since LHS = RHS, this confirms the solution for dy/dx = y/(x^2)
Answer: If you multiply a number by a fraction less than 1, the resulting product will be smaller than the original fraction.
Imagine, if you had half a pizza and you ate one-half of that. You would multiply 1/2 by 1/2 and get an even smaller number. The result would be 1/4.
On the other hand, if you multiply a number by a mixed number that is larger than one, the result would be larger than when you started.
ANSWER:
∠1 = ∠4 (Vertically opposite angle).
∠1 = ∠5 (Corresponding angle).
∠1 = ∠8 (Alternate exterior angle).
So, ∠4 , ∠5 and ∠8 are congruent to ∠1.
Answer:
1 ounce =0.0625 pounds
if 72 ounces then you multiply it by 0.0625=45
so the recipe calls for 45 pounds of meat
