What is normal distribution?
A continuous probability distribution for a real-valued random variable is called a normal distribution or a Gaussian distribution in statistics.
The normal distribution describes a symmetrical plot of data around its mean value, with the standard deviation serving as the determinant of the curve's width. The "bell curve" is used to visually represent it.
Given:
Lengths of pregnancies of women are normally distributed with a mean of 266 days and a standard deviation of 16 days.
⇒ μ = 266, σ = 16
Consider, the normal distribution formula
f(x) = (1 / σ√2π) e^(-1/2)(x - μ/ σ)^2
For x = 274,
f(274) = (1 / 16√2π) e^(-1/2)(274 - 266/16)^2
f(274) = 0.02
Hence, the percentage of children are born from pregnancies lasting less than 274 days are 0.02.
For x = 246
f(246) = (1/16√2π) e^(-1/2)(246 - 266/16)^2
f(246) = 0.02
Hence, the percentage of children are born from pregnancies lasting less than 246 days are 0.02.

You are given the difference of the numbers of boys and girls in a class and the ratio of boys to girls. How many boys and girls are in class?
3 more boys; 5 for every 4
Answer:
By using the given ratio, we will see that there are 15 boys and 12 girls.
How we can find the number of boys and girls in the class?
The given information is:
There are 3 more boys.
There are 5 boys for every 4 girls.
Now, notice that in the ratio we have a difference of 1 boy, so if we want to have a difference of 3 boys, we must multiplicate it by 3, then we get:
3*15 boys for every 3*4 girls (remember that you can multiply both quantities on the ratio and it does not change).
15 boys for every 12 girls.
Now the difference is 3.
15 - 12 = 3
So we can conclude that there are 15 boys and 12 girls.

already. -They are selling tickets to a dance performance for $10 each. They need to sell
x tickets to have enough money to buy the new dance outfits. Which inequality
represents the situation?
Answer:
x>=45 is the req. inequality
The inequality equation for the number of tickets to be sold is x ≥ 45
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the number of tickets to be sold be x
Let the total amount of money to be saved be = $ 800
The amount of money already saved = $ 350
So , the remaining amount of money = $ 800 - $ 350 = $ 450
The cost of each ticket = $ 10
So , the cost of x tickets = 10x
Now , the number of tickets to be sold to raise $ 450 is given by
10x ≥ 450 be equation (1)
On simplifying the equation , we get
Divide by 10 on both sides of the equation , we get
x ≥ 45
Therefore , the number of tickets to be sold is 45

if a sample includes 27 people, the degrees of freedom used in the formula to estimate the population variance would be
The degrees of freedom for the sample variance is equal to the number of data points in the sample minus 1, so for a sample of 27 people, the degrees of freedom would be 26.
The degrees of freedom for the sample variance is calculated by taking the number of data points in the sample and subtracting 1. In this case, the sample size is 27 people, so the number of degrees of freedom is 26. This is because we need to account for one degree of freedom in order to calculate the overall variance of the sample. The degrees of freedom is important in estimating the population variance because it helps to determine the size of the sample necessary to accurately estimate the population variance. By knowing the degrees of freedom, we can better understand the accuracy of our estimates and adjust our sample size accordingly.

nine congruent circles are inscribed in a square with a side length of 126. if a point in the square is chosen at random, what is the probability that the point is not in a circle?
There is a 21.5% chance that a point in a square with nine congruent circles drawn there won't be within one if it is chosen at random.
It is given to us that :
Nine congruent circles are inscribed in a square
The square has a side length of 126
We have to find out the probability that the point is not in a circle, if a point in the square is chosen at random.
It is known that the square has a side length of 126.
=> Area of the square = [tex](Length)^{2}[/tex]
=> Area of the square = [tex]126^{2}[/tex]
=> Area of the square = 15876 ------ (1)
It is also known to us that nine congruent circles are inscribed in the square that has a side length of 126.
=> Diameter of each circle = 126/3
=> Diameter of each circle = 42
=> Radius of each circle = 21 ------ (2)
We know that the area of a circle is given as -
Area of circle = [tex]\pi r^{2}[/tex] ------ (3)
where,
r = radius of the circle
Substituting the value of r from equation (2) in equation (1), we have
Area of circle = [tex]\pi r^{2}[/tex]
=> Area of circle = [tex]\pi (21)^{2}[/tex]
=> Area of circle = 1385.44
=> Area of 9 circles = 12468.96 ----- (4)
Now, we can say that -
Area not in a circle = Area of square - Area of 9 circles
=> Area not in a circle = 15876 - 12468.96 [From equation (1) and (4)]
=> Area not in a circle = 3407.04 ------ (5)
We know that the probability of a outcome is given as -
Probability = Number of favorable outcomes/Total number of outcomes
So, the probability that the point is not in a circle can be calculated as -
Probability = Area not in a circle/Area of square
=> Probability = 3407.04/15876
=> Probability = 0.215
=> Probability = 21.5%
Thus, if there are nine congruent circles inscribed in a square and a point in the square is chosen at random, the probability that the point is not in a circle is 21.5%.

How does the transformation of a function happen?
The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the function be represented as A
Now , the value of A is
f ( x ) = 7ˣ
The function f ( x ) is stretched vertically by a factor of 5
Let the new function be represented as g ( x )
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
So , the value of the function g ( x ) is given by the equation
g ( x ) = 5 ( f ( x ) )
g ( x ) = 5 ( 7ˣ )

model to show how the acres could be distributed for each type of tree. Using your model, complete the table.
Answer:
Step-by-step explanation:
Robb’s Fruit Farm consists of 100 acres on which three different types of apples grow. On 25 acres, the farm grows Empire apples. Mcintosh apples grow on 30% of the farm.
express cos r as a fraction in simplest terms
Answer:
[tex]\frac{5}{13}[/tex]
Step-by-step explanation:
If you have studied trigonometry, you will know that [tex]cos(\theta )=\frac{adjacent}{hypotenuse}[/tex], where the adjacent is the side with both the right angle and the angle θ, and the hypotenuse is the diagonal side.
We know here that the hypotenuse is 26.
We know do not know that adjacent where both angle R and the right angle are, but we can find it using Pythagoras' Theorem, something else which you may have studied.
[tex]a^2=c^2-b^2\\a^2=26^2-24^2\\a^2=100\\a = \sqrt{100}=10[/tex]
We now know that the adjacent is equal to 10.
Therefore, we substitute them into the cos ratio, and simplify the fraction.
[tex]cos(R)=\frac{10}{26} =\frac{5}{13}[/tex]
find the area enclosed by the curve x = t2 − 3t, y = t and the y-axis.
The area under the curve is [tex]\frac{6 \sqrt{3}}{5}[/tex].
Consider the following parametric equations:[tex]$$x=t^2-3 t \text { and } y=\sqrt{t} \text { and the } y \text {-axis. }$$[/tex]
The objective is to find area enclosed by the curve using the formula.
The area under the curve is given by parametric equations x=f(t), y=g(t), and is traversed once as t increases from α to β, then the formula for calculating the area under the curve:
[tex]$$A=\int_\alpha^\beta g(t) f^{\prime}(t) d t$$[/tex]
The curve has intersects with y-axis. so x=0
[tex]$$\begin{aligned}t^2-3 t & =0 \\t(t-3) & =0 \\t & =0 \text { or } t=3\end{aligned}$$[/tex]
Now we have to draw the graph,
Let f(t)=[tex]t^2-3 t, g(t)=\sqrt{t}$[/tex]
Differentiate the curve f(t) with respect to t.
[tex]f^{\prime}(t)=2 t-3[/tex]
Now, find the area under the curve use the above formula.
[tex]\begin{aligned}A & =\int_0^3(\sqrt{t})(2 t-3) d t \\& =\int_0^3(2 t \sqrt{t}-3 \sqrt{t}) d t \\& =\int_0^3\left(2 t^{\frac{3}{2}}-3 t^{\frac{1}{2}}\right) d t \\& =\left[2 \frac{t^{\frac{5}{2}}}{\frac{5}{2}}-3 \frac{t^{\frac{3}{2}}}{\frac{3}{2}}\right]_0^3 \\& \left.\left.=\left[\frac{4 t^{\frac{5}{2}}}{5}-2 t^{\frac{3}{2}}\right]_0^3\right]^{\frac{5}{2}}\right] \\\\\end{aligned}$$[/tex]
[tex]& =\left[\frac{4(3)^{\frac{5}{2}}}{5}-2(3)^{\frac{3}{2}}\right]-\left[\frac{4(0)^{\frac{5}{2}}}{5}-2(0)^{\frac{3}{2}}\right][/tex]
[tex]$\begin{aligned}& =\left[\frac{4(3)^{\frac{5}{2}}}{5}-2(3)^{\frac{3}{2}}\right]-\left[\frac{4(0)^{\frac{5}{2}}}{5}-2(0)^{\frac{3}{2}}\right] \\& =\frac{4(3)^{\frac{5}{2}}}{5}-2(3)^{\frac{3}{2}}-0 \\& =\frac{6 \sqrt{3}}{5}\end{aligned}[/tex]
Therefore, the area of the curve is [tex]\frac{6 \sqrt{3}}{5}[/tex].
