Let a and b be events in a sample space s such that p(a) = 0.41, p(b) = 0.46 and p(a ∩
b.= 0.14. find p(a | b).
The conditional probability that event a will occur given that event b has occurred, denoted as p(a | b), is approximately 0.3 or 30%.
Explanation:The question is asking for the conditional probability of the event a given that event b has occurred, written as p(a | b). In probability theory, the formula for conditional probability is p(a | b) = p(a ∩ b) / p(b). Here, we already know that p(a ∩ b) = 0.14 and p(b) = 0.46. Substituting these values into the formula gives us:
p(a | b) = 0.14 / 0.46 = 0.304347826.
So, the probability of event a occurring given that event b has occurred is approximately 0.3 or 30%.

2+1.25f=10−2.75f solve for f
The value of f is 0.02.
What is an expression ?Expression is a formation of numbers and variables with mathematical operations.
According to the given question we have to solve for f or we can say we have to find the value of f for the given expression which is
2+1.25f=10−2.75f (lets multiply each term by 100 to remove
decimals )
∴ 200 + 125f = 1000 - 275f
125f + 275f = 1000 - 200
400f = 800
f = 800/400
f = 2.
As we have multiplied by 100 we have to divide by 100 we obtain the exact result.
So, 2/100 is = 0.02
f = 0.02.

if f'(2) = 3.1 and g'(2)=7.3 then the graph of f(x)+g(x) has slope 10.4 at x=2.True or false
Final answer:
The statement is true, as the slope of the graph of f(x)+g(x) at x=2 is the sum of the slopes of f and g at that point, which equals 10.4.
Explanation:
The statement is true.
In calculus, the derivative of a function at a particular point measures the rate at which the function is changing at that point. It is analogous to the slope of the tangent line to the graph of the function at that point.
When we are given that f'(2) = 3.1 and g'(2) = 7.3, these values represent the slopes of the functions f and g at x = 2, respectively.
To find the slope of f(x) + g(x) at x = 2, we simply add the slopes of f and g at that point. This is based on the rule that the derivative of the sum of two functions is the sum of their derivatives, or symbolically, (f+g)' = f' + g'.
Therefore, the slope of the graph of f(x)+g(x) at x=2 is indeed 10.4 (3.1 + 7.3).
What is the probability that x is between $34 and $38?
The probability that ( x) is between $34 and $38 is 0.6826 or 68.26%.
To find the probability that a random variable ( x) is between $34 and $38, we need to use the probability density function (PDF) if ( x) follows a continuous distribution. Let's assume ( x ) follows a normal distribution with a mean [tex](\( \mu \))[/tex] of $36 and a standard deviation [tex](\( \sigma \))[/tex] of $2.
Calculate the z-scores for $34 and $38:
[tex]\[ z_1 = \frac{34 - 36}{2} = -1 \][/tex]
[tex]\[ z_2 = \frac{38 - 36}{2} = 1 \][/tex]
Look up the z-scores in the standard normal distribution table:
[tex]\[ P(z_1 < Z < z_2) = P(-1 < Z < 1) \][/tex]
Find the probabilities corresponding to these z-scores:
[tex]\[ P(Z < 1) = 0.8413 \][/tex]
[tex]\[ P(Z < -1) = 0.1587 \][/tex]
Subtract the two probabilities:
[tex]\[ P(-1 < Z < 1) = P(Z < 1) - P(Z < -1) = 0.8413 - 0.1587 = 0.6826 \][/tex]
So, the probability that ( x) is between $34 and $38 is 0.6826 or 68.26%.
Determine whether or not f is a conservative vector field. if it is, find a function f such that f = ∇f. if it is not, enter none. f(x, y) = (yex + sin y) i + (ex + x cos y) j
The vector field f(x, y) = (yex + sin y) i + (ex + x cos y) j is conservative because its curl vanishes everywhere. The function F such that ∇F = f is yex + cos y + C.
Explanation:To determine if the given function f(x, y) = (yex + sin y) i + (ex + x cos y) j is a conservative vector field, we need to see if the curl of the vector field vanishes everywhere. The curl of a vector field in two dimensions is the partial derivative of the j component with respect to x minus the partial derivative of the i component with respect to y.
For f(x, y), the partial derivative of the j component (ex + x cos y) with respect to x is ex + cos y, and the partial derivative of the i component (yex + sin y) with respect to y is ex + cos y. Both derivatives are equal, implying the curl is zero. Hence, f(x, y) is a conservative vector field.
Next, to find a function F such that ∇F = f, we need to integrate. The potential function, F, can be obtained by integrating the i component of f with respect to x (since it does not involve y), and the j component of f with respect to y (since it does not involve x): ∫yex dx + ∫sin y dy = yex + cos y + C. This is the function F such that ∇F = f.

Prove or disprove that the product of two irrational numbers is irrational
The product of two irrational numbers can be either rational or irrational.
The product of two irrational numbers is not always irrational. To understand this, let's consider an example and a counterexample.
Example of an Irrational Product
Take the square root of 2 (\/(2)) and the square root of 3 (\/(3)). Both of these numbers are irrational. Their product is:
\/2 × \/3 = \/6
Since \/6 cannot be expressed as a fraction of two integers (making it irrational), this is an example where the product of two irrational numbers is irrational.
Counterexample of a Rational Product
Now, consider another example with \/(2) and \/(2). Since both are irrational, their product is:
\/2 × \/2 = 2
Here, 2 is a rational number because it can be written as a fraction (2/1). Therefore, this is a counterexample where the product of two irrational numbers is rational.
In summary, the product of two irrational numbers can be either rational or irrational depending on the specific numbers involved.
The perimeter of a college athletic field is 104 meters and the length is 16m more than the width find the length and width
The length and width of the rectangle will be 19 meters.
What is the perimeter of the rectangle?The sum of all the sides of the rectangle will be known as the perimeter of the rectangle. Let L be the length and W be the width of the rectangle.
Then the perimeter of the rectangle will be
Perimeter of the rectangle = 2(L + W) units
The perimeter of a college athletic field is 104 meters and the length is 16 meters more than the width.
L = 14 + W
Then the length and width of the rectangle will be
P = 2(L + W)
104 = 2(14 + W + W)
52 = 14 + 2W
2W = 38
W = 19 meters

What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given,
A father is three times as old as his son
Sum of their age is 76 years
Let age of son is x, age of father = 3x
x + 3x = 76
4x = 76
x = 76/4
x = 19
