Suppose that 25% of adults exercise regularly. If 11 adults randomly selected, what is the probability that four or less exercise regularly
Answers
The probability that four or less adults exercise regularly out of 11 randomly selected adults is approximately 0.9824.
This problem can be solved using the binomial distribution, since we are interested in the probability of a certain number of successes (adults who exercise regularly) in a fixed number of trials (selecting 11 adults randomly).
Let X be the number of adults who exercise regularly out of 11. Then X has a binomial distribution with parameters n = 11 and p = 0.25, since the probability of success (an adult who exercises regularly) is 0.25.
We want to find the probability that four or less adults exercise regularly, which is equivalent to finding the probability of X ≤ 4. We can use the binomial cumulative distribution function to calculate this probability:
P(X ≤ 4) = Σ P(X = k), for k = 0, 1, 2, 3, 4
Using a calculator, spreadsheet software, or a binomial probability table, we can find the probabilities for each value of k, and then add them up to get the cumulative probability:
P(X = 0) = (11 choose 0) * (0.25)^0 * (0.75)^11 = 0.0563
P(X = 1) = (11 choose 1) * (0.25)^1 * (0.75)^10 = 0.2015
P(X = 2) = (11 choose 2) * (0.25)^2 * (0.75)^9 = 0.3159
P(X = 3) = (11 choose 3) * (0.25)^3 * (0.75)^8 = 0.2747
P(X = 4) = (11 choose 4) * (0.25)^4 * (0.75)^7 = 0.1340
P(X ≤ 4) = 0.0563 + 0.2015 + 0.3159 + 0.2747 + 0.1340 = 0.9824
Therefore, the probability that four or less adults exercise regularly out of 11 randomly selected adults is approximately 0.9824.

Equation of line in ordinary form: y = 2x+0
Equation of line in standard (general) form: 2x - y = 3
What is Slope?
The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).
a) Ordinary form =>
Slope Intercept Form:
y = mx+b
where m is the slope of the line
(Δy/Δx)
and b is the y-intercept.
For a line with slope 2 and point (-3,-6), plug 2 in for m, -3 for x, -6 for y, and solve for b.
-6 = 2(-3) + b
-6 = -6 + b
6 - 6 = b
b = 0
The equation in slope intercept form is
y = 2x+0
b) Standard form =>
Point Slope Form:
(y - y1) = m(x - x1)
Where m is the slope of the line
(Δy/Δx), y1 is the y coordinate of a point, and x1 is the x coordinate of a point.
For a line with slope 2 and point (-3,-6), plug 2 in for m, -3 for x1, -6for y1,
(y - (-6)) = 2(x - (-3))
Standard Form:
Ax + By = C
Where A, B, and C are integers. To write an equation in standard form, rewrite the equation in point slope form so that it fits the formula for standard form.
(y - (-6)) = 2(x - (-3))
(y + 6) = 2(x + 3)
y + 6 = 2x + 3
2x - y = 6 - 3
2x - y = 3
Hence, Equation of line in ordinary form is y = 2x+0
Equation of line in standard (general) form is 2x - y = 3

Answers
It's important to note that if any of the resulting inequalities is false, then the ordered pair is not a solution. Therefore, it's crucial to check both inequalities to make sure that the ordered pair satisfies both of them.
To verify that an ordered pair is a solution of a system of linear inequalities, you need to substitute the values of the ordered pair into the inequalities and check if they are true. There are different ways to do this, but the most common ones are:
1. Substitute the x value into the inequalities and solve each for y: This involves replacing the x variable with its value in each inequality and then solving for y. If the resulting inequality is true, then the ordered pair is a solution. Repeat the process with the other inequality.
2. Substitute the y value into the inequalities and solve each for x: This is similar to the previous method, but you replace the y variable with its value and solve for x. If both resulting inequalities are true, then the ordered pair is a solution.
3. Substitute the x and y values into the inequalities and verify that the statements are true: This involves plugging in the values of x and y into both inequalities and checking if they are both true. If they are, then the ordered pair is a solution.

and (1,1,0,1).
Then, I got (0,1,0,0)+a∗(1,1,1,0)+b∗(1,1,0,1

Therefore, all possible results are (0,1,0,0),(1,0,1,0),(1,0,0,1),(0,1,1,1)
Would this be correct?
Answers
The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).
Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.
Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).
Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).
Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).
To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.
(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)
Expanding this expression, you get:
(0+a+b, 1+a+b, 0+a, 0+b)
Simplifying, you obtain the following set of solutions:
(0, 1, 0, 0)
(1, 2, 1, 0)
(1, 2, 0, 1)
Therefore, the correct set of possible results would be:
(0, 1, 0, 0)
(1, 2, 1, 0)
(1, 2, 0, 1)
Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

Weights of chocolate chip bags follow an approximate normal distribution with mean 12.16 ounces and standard deviation of 0.12 ounce. What is the probability that a randomly selected bag weighs between 11.95 and 12.05 ounces?
Answers
The probability that a randomly selected bag weighs between 11.95 and 12.05 ounces can be calculated using the normal distribution.
To find the probability that a randomly selected bag weighs between 11.95 and 12.05 ounces, we need to calculate the area under the normal distribution curve between these two values. We can standardize the values using the z-score formula: z = (x - μ) / σ, where x is the value, μ is the mean, and σ is the standard deviation.
For 11.95 ounces:
z1 = (11.95 - 12.16) / 0.12
For 12.05 ounces:
z2 = (12.05 - 12.16) / 0.12
We can then look up the corresponding probabilities for z1 and z2 in the standard normal distribution table or use statistical software to find the area between these two z-scores. This area represents the probability that a randomly selected bag weighs between 11.95 and 12.05 ounces.

If a food item with an original (AP) weight of 4 pounds at a cost of $1.10 per pound yields a servable weight of 2 pounds, what is the cost per servable pound for this food item? a. $0.50 b. $1.50 c. $2.20 d. $4.40
Answers
Given that the cost is $1.10 per pound, we can calculate the cost per servable pound by dividing the total cost ($1.10 * 4 pounds) by the servable weight (2 pounds). Therefore, the correct option is c. $2.20.
The original weight of the food item is 4 pounds, and the cost per pound is $1.10. Therefore, the total cost of the food item is 4 pounds * $1.10 = $4.40.
The servable weight of the food item is 2 pounds. To find the cost per servable pound, we divide the total cost ($4.40) by the servable weight (2 pounds):
Cost per servable pound = Total cost / Servable weight = $4.40 / 2 pounds = $2.20.
Hence, the cost per servable pound for this food item is $2.20. Therefore, the correct option is c. $2.20.

Answers
Answer:
27°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let the third angle be x , then
x + 90° + 63° = 180°
x + 153° = 180° ( subtract 153° from both sides )
x = 27°
Answer:
27 degrees
Step-by-step explanation:
A right angled triangle has 1 angle as 90 degree. And as you know the other angle is 63 degree, and the angle sum property of a triangle is 180 degrees. So-
Let's take 'x' as the other angle.
90 + 63 + x = 180
153 + x = 180
x = 180 - 153 = 27
x = 27 degrees
So, the other angle is 27 degrees.
All the angles of the right-angled triangle are- 90, 63, 27.

Estimate the disease probability in one city given the probability is very low nationwide. Randomly asked 1000 person in this city, with all negative response (NO disease). What is the probability of disease in this city?
Answers
The probability of the disease is very low nationwide. We need to estimate the disease probability in one city. The probability of disease in this city is 0.0976% (0.000976 or 0.00001) or 99.9024%.
Solution:Let's assume that the probability of the disease in the city is p.
We know that the probability of having no disease is (1-p).
Out of the 1000 people randomly asked, all of them have no disease which means they all responded negatively.
The probability of one person not having a disease = 1-p
Probability of 1000 people not having a disease =
(1-p) × (1-p) × (1-p) × ... (1000 times)
= (1-p)^1000
Given that the probability of disease is very low nationwide.
The probability of having no disease is high (say 0.9).
So the probability of a disease in the city = 1 - probability of no disease in the city
= 1 - (1-p)^1000= 1 - (1-0.9)^1000
= 1 - 0.000976
= 0.999024
= 99.9024%
Therefore, the probability of disease in this city is 0.0976% (0.000976 or 0.00001) or 99.9024%.
