x - y = 3
x + y= 13

2x = 16
x = 16/2
x = 8
8 + y = 13

the random variable x is known to be uniformly distributed between 5 and 15. compute e(x), the expected value of the distribution.
The expected value of the distribution for the random variable x is 10. This means that if we were to repeat the experiment many times, the average value of x would converge to 10, with some fluctuations around this central value due to the randomness of the uniform distribution.
The expected value of a random variable is a measure of the central tendency of its distribution, representing the average value that we would expect to observe over many trials or events. In the case of a uniform distribution, where all values between the minimum and maximum are equally likely, the expected value can be calculated as the average of the two endpoints:
e(x) = (5 + 15) / 2 = 10
Therefore, the expected value of the distribution for the random variable x is 10. This means that if we were to repeat the experiment many times, the average value of x would converge to 10, with some fluctuations around this central value due to the randomness of the uniform distribution.
It is important to note that the expected value is not always equal to the most common or typical value of a distribution, but rather represents a measure of the overall tendency of the data. Other measures such as the variance or standard deviation can provide additional information about the spread or variability of the distribution, which can be useful for making statistical inferences or predictions.

a recent survey found that of all adults over wear glasses for driving. in a random sample of adults over , what is the probability that at least six wear glasses?
Let p be the probability of an adult over 50 wearing glasses for driving. Since we don't know the value of p, we can't use the binomial distribution directly. However, we can use the normal approximation to the binomial distribution since n is large (assuming n * p >= 10 and n * (1-p) >= 10).
Let X be the number of adults over 50 wearing glasses for driving in a random sample of n adults. Then X ~ Binomial(n, p) can be approximated by a normal distribution with mean µ = n * p and standard deviation σ = sqrt(n * p * (1-p)).
We want to find the probability that at least six adults over 50 in a random sample of n wear glasses for driving. This is equivalent to finding P(X >= 6) = 1 - P(X < 6) using the normal approximation.
To apply the normal approximation, we need to standardize the random variable X:
Z = (X - µ) / σ
Using continuity correction:
P(X >= 6) = P(X > 5.5)
Z = (5.5 - n * p) / sqrt(n * p * (1-p))
We can use the standard normal distribution table or calculator to find the probability:
P(Z >= (5.5 - n * p) / sqrt(n * p * (1-p)))
Since we don't know the value of p, we can use a conservative estimate of p = 0.5 (assuming 50% of adults over 50 wear glasses for driving). Then:
P(Z >= (5.5 - n * 0.5) / sqrt(n * 0.5 * (1-0.5)))
For example, if we sample n = 100 adults over 50, the probability of at least six wearing glasses is:
P(Z >= (5.5 - 100 * 0.5) / sqrt(100 * 0.5 * (1-0.5)))
= P(Z >= 0.5)
Using a standard normal distribution table or calculator, P(Z >= 0.5) = 0.3085.
Therefore, the probability of at least six adults over 50 wearing glasses for driving in a random sample of 100 is approximately 0.3085 or 30.85%.

Answer:
MQ and QP are equal, MO and OP are equal, x=2
Step-by-step explanation:
QO is a perpendicular bisector of MP meaning that Triangle MQP must be isosceles (if at least two of the following, angle bisector, median, or an altitude, coincide in a triangle, that triangle must be isosceles). In this case an altitude and median coincide in triangle MQP. This means that MQ=QP as the triangle is isosceles. And also MO=OP because QO is a median. Now solving for x, 11=4x+3, 8=4x, x=2.

The number of new cases of a disorder in a population that emerge in a particular time interval is called the incidence.
About incidenceIncidence refers to the rate at which a new event occurs in a population. Incidence takes into account the variable time period during which a disease-free individual becomes at risk of spreading the disease.
In incident calculations, the quantifier is the number of events that have occurred in a given time. Then the quantifier of the denominator is the population that is at risk of experiencing the event during this period.
Simply put, incidence refers to new cases and is used to determine the etiology of the disease. While prevalence is more widely used to refer to health status in certain populations.

When s= 25, P = 1400.
Work out the speed (to 1 DP) when the power is 1820 watts
m/s
Answer:
28.5 m/s
Step-by-step explanation:
Given that power is 1400 W when speed is 25 m/s, and power is proportional to the square of speed, you want the speed when the power is 1820 W.
ProportionSince power is proportional to the square of speed, the ratio of speed squared to power is a constant:
s²/P = 25²/1400 = x²/1820
where x is the unknown speed.
SolutionWe can find the value of x by multiplying by 1820 and taking the square root:
x² = 25²(1820/1400)
x = 25√(1820/1400) = 25√1.3 ≈ 28.5 . . . . m/s

the graph of polygon fghi is shown. graph the image of fghi after a refelction across the line y=-1. include the line of reflection. then write the coordinates of the image
The coordinates of the reflected polygon F'G'H'I' are as follows:
F'(-2, -1), G'(5, -4), H'(8, -5), and I'(6, -2).
What is the reflection?
In mathematics, reflection is defined as the mirror image of a figure crossing a line (drawn or imagined), known as the line of reflection.
The vertices of the polygon FGHI are as follows:
F(2, -1)
G(5, 2)
H(8, 3)
I(6, 0)
To reflect the polygon FGHI across the line y = -1, we need to flip the points over the line.
Now we can reflect each of the points of the polygon across the line y = -1 to get the image:
F(2, -1) stays in the same place because it lies on the line of reflection.
G(5, 2) is reflected to G'(5, -4) by flipping it vertically across the line y = -1.
H(8, 3) is reflected to H'(8, -5), and
I(6, 0) is reflected to I'(6, -2).
Hence, The coordinates of the reflected polygon F'G'H'I' are as:
F'(-2, -1), G'(5, -4), H'(8, -5), and I'(6, -2).

Enter your answer using interval notation. If an answer does not exist, enter DNE.
f is concave up on:
f is concave down on:
Therefore, the intervals of concavity of f are: f is concave up on the entire real number line: (-∞, +∞).
To determine the concavity of a function, we look at the sign of its second derivative. If the second derivative is positive, the function is concave up, meaning it curves upward. If the second derivative is negative, the function is concave down, meaning it curves downward.
In the given equation, \(f''(x) = 40x^6(x + 3)^3(x^2 + 49)\), we can see that all the terms are non-negative. The term x^6 is always non-negative for any real value of x, as the exponent is even. The terms \((x + 3)^3\) and \((x^2 + 49)\) are both polynomials, and the sum or product of polynomials is always non-negative if all the individual terms are non-negative.
Since f''(x) is the product of non-negative factors, it can only be positive or zero. This means that the function is always concave up, and it never changes its concavity throughout the entire real number line.

Step-by-step explanation:
-kpl and npm are vertical angles, so they're congruent
-npm and lpm are supplementary angles, meaning they add to 180 degrees
we r given:
npm = 14x - 22
lpm = 7x + 4
add these and set equal to 180:
14x - 22 + 7x + 4 = 180
then combine like terms:
21x -18 = 180
isolate the variable by adding 18 on both sides:
