The standard deviation for the number of people with the genetic mutation in a group of 1000 individuals is approximately 4.89.
To find the standard deviation for the number of people with a particular genetic mutation in a group of 1000 individuals, we first need to understand the concept of binomial distribution.
Binomial distribution is a statistical probability distribution that represents the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes (success or failure).
In this case, the probability of success (having the genetic mutation) is 0.04, and the probability of failure (not having the mutation) is 0.96. Thus, we can model the number of people with the mutation in a group of 1000 individuals using a binomial distribution with n = 1000 and p = 0.04.
The formula for the standard deviation of a binomial distribution is:
σ = √(np(1-p))
Where σ is the standard deviation, n is the number of trials, and p is the probability of success. Plugging in the values, we get:
σ = √(1000 x 0.04 x 0.96) = 4.89
In other words, we can expect that the number of people with the genetic mutation in a group of 1000 individuals will vary around the mean of 40 (1000 x 0.04) by about 4.89, with about 68% of the observations falling within one standard deviation of the mean.

the elephant population in northwestern namibia and etosha national park can be predicted by the expression 2 , 649 ( 1.045 ) b , where b is the number of years since 1995. what does the value 2,649 represent?
The value 2,649 represents the estimated population of elephants in Northwestern Namibia and Etosha National Park in 1995 and the estimated population was 618.4.
The formula for population growth can be represented as:
P = P0ert
Here, P is the population of elephants, P0 is the initial population, e is the base of the natural logarithm, r is the rate of growth or decay, and t is the time in years.
Now, as per the given data, P = 2,649P0 = initial population r = 1.045 (as per the given expression)b = t - 1995 (as per the given formula)Now, putting these values in the population growth formula,
P = P0ert2,649 = P0e1.045(b-1995)Dividing by P0 on both sides, we get:e1.045(b-1995) = 2649/P0
Taking the natural logarithm on both sides,
ln e1.045(b-1995) = ln (2649/P0)
Applying the property of logarithm,1.045(b-1995) ln e = ln (2649/P0)1.045(b-1995) = ln (2649/P0)
vAs we need to find the value of P0, substitute the value of b = 0,1.045(0-1995) = ln (2649/P0)-1.045*1995 = ln (2649/P0)ln (2649/P0) = -2069.95
Taking anti-logarithm or exponentiation on both sides,2649/P0 = eln (2649/P0) = e^(-2069.95)2649/P0 = 4.29P0 = 2649/4.29P0 = 618.4
Therefore, the estimated population of elephants in Northwestern Namibia and Etosha National Park in 1995 was 618.4.

Write the equation of a circle with a center of (1, -5) and a radius of √5
Simplifying this equation gives: [tex](x - 1)^2+(y+5/8)^2=5[/tex].
What is the circle?A circle is a geometrical shape that consists of all the points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the circle is called the radius, and the distance across the circle passing through the center is called the diameter. The circumference of a circle is the distance around the edge of the circle, and it is calculated as 2 times pi (π) times the radius. Circles are found in many areas of mathematics and the physical world, and they have important applications in geometry, trigonometry, calculus, physics, and engineering, among other fields.
The equation of a circle with center (a, b) and radius r is given by:
[tex](x - a)^2 + (y - b)^2 = r^2[/tex]
In this case, the center is (1, -5/8) and the radius is √5. So, the equation of the circle is:

Out of 80 customers at an ice cream van, 48 had syrup, 28 had sprinkles and 16 had both
toppings on their ice cream. Use a Venn diagram to find the probability that a randomly
selected customer doesn't have either topping, given that they don't have sprinkles.
I know the answer is 20/52, I just can’t work out how to get to that answer…
Answer:
20/52 or simplified to 5/13
Step-by-step explanation:
The Venn Diagram is provided
Let
n(A) = number of customers who had syrup
n(B) = number of customers who had sprinkles
n(A and B) = number of customers who had both syrup and sprinkles = 16
This would be the number in the overlapping region
n(A or B) = number of customers who had either syrup or sprinkles or both
= n(A) + n(B) - n(A and B)
= 48 + 28 - 16
= 60
Therefore number of customers who had neither topping = 80 - 60 = 20
This number is indicated outside both circles but within the rectangle
The number of customers who had only syrup is given by set difference
= No. of customers who had syrup - No. of customers who had both
= n(A) - n(A and B)
= 48 - 16
= 32
This is the figure inside the left circle
Let's consider the statement: Customers who didn't have sprinkles
This would be customers who had only syrup(32) + customers who had neither topping(20)
= 32 + 20 = 52
Number of customers who did not have either topping = 20
P(selected customer doesn't have either topping, given that they don't have sprinkles)
= 20/52
= 5/13

f a barometer were built using water instead of Hg, how high would the column of water be if the pressure were 1 atm, knowing that the density of water is 13.6 times lower than that of mercury?
The height of the water column would be 1033.6 cm if the pressure were 1 atm.
SOLUTION:
If a barometer were built using water instead of mercury, and the pressure were 1 atm, the height of the water column would be:
1. First, find the height of the mercury column at 1 atm. The standard height is 760 mm (or 76 cm) for mercury.
2. Since the density of water is 13.6 times lower than that of mercury, the water column needs to be 13.6 times higher than the mercury column to exert the same pressure.
3. Multiply the height of the mercury column (76 cm) by 13.6:
76 cm x 13.6 = 1033.6 cm.
So, the height of the water column would be 1033.6 cm if the pressure were 1 atm.

A rectangle has an area of 717. 8m2. One of the sides is 7. 4m in length. Work out the perimeter of the rectangle
The perimeter of the rectangle is approximately 208.9 meters.
To find the perimeter of the rectangle, we need to know the length of the other side.
Let's use the formula for the area of a rectangle:
area = length x width
We know that the area is 717.8 m^2 and one of the sides (width) is 7.4 m. So we can rearrange the formula to solve for the length:
length = area / width
length = 717.8 / 7.4
length ≈ 97.05 m
Now we have both the length and width of the rectangle, so we can find the perimeter:
perimeter = 2 x (length + width)
perimeter = 2 x (97.05 + 7.4)
perimeter = 2 x 104.45

Given that330 litres per hour needs to be converted into millimeters per minute.
Conversion factor: 1 litre =1000 cubic centimeter 1 cubic centimeter =1 millimeter³
∴ 1 litre=1000 millimeter³
∴ 1 litre per hour=1000 millimeter³ per hour
Also, 1 hour = 60 minutes
∴ 1 hour = 60 × 60 seconds = 3600 seconds
∴ 1 second = 1/3600 hours=0.0002778 hours
Thus, 1 litre per hour =1000/3600 millimeter³ per second =0.2778 millimeter³ per second
Therefore, 330 litres per hour = 330 × 0.2778 millimeter³ per second=91.494 millimeter³ per second
Also, 1 minute =60 seconds
∴ 1 minute = 60 × 60 seconds=3600 seconds
∴ 1 second = 1/60 minutes=0.01667 minutes
Thus, 91.494 millimeter³ per second = 91.494/0.01667 millimeter³ per minute = 5489.64 millimeter³ per minute

The relation in which a college student is related to another if and only if they have attended class together is an example of an equivalence relation.
An equivalence relation must satisfy three properties :Reflexivity: Every element of the set is related to itself. In this case, every student has attended class with themselves, so the relation is reflexive.
Symmetry: If one element is related to another, then the second element is also related to the first. In this case, if student A has attended class with student B, then student B has also attended class with student A, so the relation is symmetric.
Transitivity: If one element is related to a second, and the second is related to a third, then the first is related to the third. In this case, if student A has attended class with student B, and student B has attended class with student C, then student A has also attended class with student C, so the relation is transitive.

The leaves on the tree make it difficult for Corey to watch the bird, so he moves 10 feet further away from the tree to get a better view. Now his angle of elevation is 56°.
What is the height of the tree? Round your answer to the nearest foot.
pls help
The height of the tree is approximately 76 feet.
What is the angle of elevation?
The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.
We can use tangent to set up the following two equations based on the given angles of elevation:
tan(62°) = h/x
tan(56°) = h/(x+10)
We can rearrange the first equation to solve for "h":
h = x * tan(62°)
tan(56°) = (x * tan(62°)) / (x+10)
We can solve for "x" by multiplying both sides by (x+10) and rearranging:
x = 10 * (tan(62°) - tan(56°)))
Now we can substitute this value for "x" into either of the two equations we set up earlier to find the height of the tree "h". Using the first equation, we get:
h = x * tan(62°) ≈ 76 feet
Therefore, the height of the tree is approximately 76 feet.

Therefore, the store owner should mix 15 pounds of chocolate costing $21.10 per pound with 14 pounds of trail mix costing $3.10 per pound to create a mixture worth $12.41 per pound.
To check this answer, we can verify that the total cost of the mixture equals the total cost of the chocolate and trail mix:
15(21.10) + 14(3.10) = 315 + 43.40 = 358.40
And the total weight of the mixture is:
15 + 14 = 29
So the cost per pound of the mixture is:
358.40 / 29 = 12.41
which matches the desired cost per pound.

The expression g(f(x)) simplifies to -6x + 6, and we can see that the coefficient of x is -6 and the constant term is 6.
What is a function f(x)?A function f(x) is a mathematical relationship that assigns a unique output value (or range value) for every input value (or domain value) from a specified set. In other words, a function takes one or more input values and produces a single output value based on a specific rule or set of rules.
According to question:To find g(f(x)), we need to substitute the expression for f(x) into g(x) wherever x appears, since g(x) is being evaluated at the value of f(x). That is, we need to substitute -2x+5 for x in the expression for g(x). This gives:
g(f(x)) = g(-2x+5)
= 3(-2x+5) - 9
= -6x + 15 - 9
= -6x + 6
So, g(f(x)) = -6x + 6.
Therefore, the expression g(f(x)) simplifies to -6x + 6, and we can see that the coefficient of x is -6 and the constant term is 6. Thus, we can express the response as follows:
g(f(x)) = -6x + 6
= [-6]x + [6]

Answer:
No.
Step-by-step explanation:
Line XY will be tangent to Circle W when XY is perpendicular to the radius XW. We can test if it is perpendicular by using Pythagoras theorem as it only works on right angled triangle. If the angle WXY is 90 degrees (XY ⊥ WX) then the theorem should work.
[tex](XY)^2=(WX)^2+(XY)^2\\R.H.S = 66^2+54^2 = 7272\\L.H.S = 87^2 = 7569\\R.H.S \neq L.H.S[/tex]
Thus the angle is not 90 degrees since the Pythagoras theorem doesn't work thus the line is not tangent since it is not at 90 degrees with the radius WX.
Answer:
not a tangent
Step-by-step explanation:
if XY is a tangent to the circle then ∠ WXY = 90°
using converse of Pythagoras' identity.
if the square of the longest side is equal to the sum of the squares on the other 2 sides , then the triangle is right.
longest side is WY
WY² = 87² = 7569
WX² + XY² = 66² + 54² = 4356 + 2916 = 7272
since WY² ≠ WX² + XY² , then Δ WXY is not right
then XY is not a tangent to the circle
