Using a mean and standard deviation as inputs, the following formula can be used to get the percentile of a normal distribution:
Percentile Value is equal to z +.
What is standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers.
While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.
The lower case Greek letter (sigma), for the population standard deviation, or the Latin symbol s, for the sample standard deviation, are most frequently used in mathematical texts and equations to indicate standard deviation.
Standard deviation may be written as SD.
A random variable, sample, statistical population, data set, or probability distribution's standard deviation is equal to the square root of its variance.
Though in algebra, it is simpler
According to our question-
a. 157 is less then 161
b. n>173, n be a real number.

Yujin Pon has a principal of $900 in her savings Iccount on October 1. The money earns interest at a rate of 6.5% compounded quarterly until July 1 of the following year. What is the amount in the account on July 1?
а.$914.63
b. $943.75
c.$943.87
d. $944.59
Answer: The correct answer is c. $943.87.
Step-by-step explanation: To solve this problem, we need to first determine the length of time between October 1 and July 1 of the following year. This is a period of 9 months, or 3 quarters. We can then use this information to calculate the amount of interest earned over this time period.
The principal in Yujin Pon's account is $900, and the interest rate is 6.5% compounded quarterly. This means that for each quarter, the account will earn 6.5/4 = 1.625% in interest. Over the 3 quarters between October 1 and July 1 of the following year, the account will earn a total of 1.625% * 3 = 4.875% in interest.
To calculate the amount of interest earned, we can multiply the principal by the interest rate:
Interest = Principal * Interest Rate
= $900 * 0.04875
= $43.87
The total amount in the account on July 1 will be the original principal plus the amount of interest earned over the 3 quarters:
Total = Principal + Interest
= $900 + $43.87
= $943.87
Therefore, the correct answer is c. $943.87.
Solve for y. Find m∠ C and m∠ D. Show all work.
The value of y is 10. The measure m∠ C and m∠ D are 40° and 76° respectively.
What is external angle?
The angle created when a transversal cuts one of two lines and is located outside of the line. It describes the angle between a side of a polygon and an expanded adjacent side.
The measure of an external angle of a triangle is equal to the sum of opposite interior angles.
∠DEF is an exterior angle. The opposite interior angles of ∠DEF are m∠ C and m∠ D
Therefore,
m∠ C + m∠ D = ∠DEF
4y° + (7y + 6)° = 116°
Add like terms
11y + 6 = 116
Subtract 6 from both sides:
11y = 110
Divide both sides by 11:
y = 10
Putting y = 10 in m∠ C = 4y° and m∠ D = (7y + 6)°
m∠ C = 40°
m∠ D = 76°

cory has $3$ apples, $2$ oranges and $2$ bananas. if cory eats one piece of his fruit per day for a week and the pieces of fruit within each category are indistinguishable, in how many orders can cory eat the fruit? one such order is $aaaoobb.$
Then the orders can Cory eat the fruit is = 25
Given that,
If Cory has eat apples = 3$
If Cory has eat oranges = 2$
If Cory has eat bananas = 2$
Total eat fruits = 3 + 2 + 2
Total eat fruits = 7$
We have to express the amount of total fruits as an equation.
The amount of apples will be x,
The amount of oranges will be y,
The amount of bananas will be z
The amount of apples multiplied by 7 because they ate each day of the week.
7*(x) + y + z = now we have to replace the values of x, y and z with the ones that gave us the problem
Then,
x = 3
y = 2
z = 2
So,
We can write,
7*(x) + y + z = 7 *(3) + 2 + 2
= 21 + 2 + 2
= 25

Name the property of real numbers illustrated by the equation. -2(x 4)=-2x-8
Distributive property of real numbers illustrated by the equation. -2(x 4)=-2x-8
The equation -2(x 4)=-2x-8 is an example of the distributive property of real numbers. This property states that when a number is multiplied by a group of numbers that are being added together, the number can be distributed to each of the terms in the group. To rewrite this equation as -2x + (-2)(-4) = -2x - 8, the number -2 is allocated to each of the terms in the group (x and -4) in this equation.Simplifying further, we get -2x - 8 = -2x - 8.
-2(x 4) = -2x - 8

A= 0.95
C= (blank)
opposite leg ++ adjacent leg
A= 3.06
C= (blank)
The required trigonometric ratios of angle C in the given table are
(a) adjacent leg ÷ hypotenuse (cos C) = 0.95
(b) opposite leg ÷ hypotenuse (sin C) = 0.31
(c) opposite leg ÷ adjacent leg (tan C) = 0.33
What are required trigonometric ratios?The three important trigonometric ratios are:
sin θ = opposite leg ÷ hypotenuse
cos θ = adjacent leg ÷ hypotenuse
tan θ = opposite leg ÷ adjacent leg
Calculation:In the given right-angle triangle, the ratios are given as
cos A = adjacent leg ÷ hypotenuse = 0.31
sin A = opposite leg ÷ hypotenuse = 0.95
tan A = opposite leg ÷ adjacent leg = 3.06
These ratios are w.r.t the angle A.
Since we know that, in the right angle triangle,
∠A + ∠B + ∠C = 180°
⇒ ∠A + 90° + ∠C = 180°
⇒ ∠A = 180° - 90° - ∠C
∴ ∠A = 90° - ∠C
So, the trigonometric ratios w.r.t the angle C are:
(a) cos A = cos (90° - ∠C) = sin C
But we have cos A = 0.31
∴ sin C = 0.31
(b) sin A = sin (90° - ∠C) = cos C
But we have sin A = 0.95
∴ cos C = 0.95
(c) Then, tan C = sin C/cos C
Here we got sin C = 0.31 and cos C = 0.95
So, tan C = 0.31/0.95 = 0.33

The function rule that could be represented by the graph is given as follows:
y = 2x³ + x - 3.
How to define the function?The first step in defining the function is looking at it's y-intercept, which is the value of y when the graph of the function crosses the y-axis.
This value is of -3, hence the function can be defined as follows:
f(x) = ax^n + x - 3.
Then we look at the behavior of the function. It has an inflection point, as it is concave down and then it becomes concave up, hence:
It's second derivative is of the first degree.It's first derivative is of the second degree.The function is of the third degree, hence n = 3.Thus:
f(x) = ax³ + x - 3.
Then we look at the x-intercept, meaning that when x = 1, y = 0, this the leading coefficient is obtained as follows:
0 = a + 1 - 3
a = 2.

Given that:

standard deviation = 0.3
P(18.295 < x < 19.705)
The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an event can be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
= P[(18.295 - 19.0)/0.3) < (x-mean)/standard deviation < (19.705-19.0)/0.3)]

does anyone have the answer
Angle BAC is an inscribed angle, which means that its size is equal to the size of the arc it attempts to represent, arc BC, and that arc BC is the arc that it attempts to represent. Taking that portion of 360° will allow us to calculate the angle 45°.
What is the measure of ∠ BAC?One degree is represented by each of these tiny notches on a scale. Therefore, eleven degrees are equal to 10 plus one. And that is how we responded: the BAC angle is eleven degrees in length.Percentages are all that are involved here. The proportion of the surface area that is represented by 4.5 must first be calculated. Calculating the overall surface area is necessary to accomplish that. Radius equals six if the diameter is twelve.A = π * 6 * 6 = 36π
The current value
Taking that portion of 360° will allow us to calculate the angle:
0.125 * 360 = 45°.

What are inequalities?Inequality refers to a way of representing relationships between variables at the left hand side of equation to the variables to the right hand side of an equation.
The signs used in inequality are of 4 types namely
less thangreater thanless than or equal togreater than or equal toThe strict inequality are those inequality that the equation fails when equality sign is used to represent the relationship of the left and right hand side of an equation.. The inequality sign used here is only less than or greater than
The non strict inequality maintains the balance between both sides of the equation whether the equality is used or not. Instances include "less than or equal to" OR "greater than or equal to"
