The total number of candies in the store is 312. It is obtained by using the concept of exponent and power on the given problem.
What is an Exponent?
The number of times a quantity is multiplied by itself is referred to as an exponent or power of the given quantity. For eg: 25, where 5 is an exponent or power of 2 and 2 is called the base of exponent 5. Any quantity raised to the power 0 always returns 1 as result.
Calculation of the total number of candies in the store
(36)2 * 30
Using the properties of an exponent, we have
A number with an exponent of 0 always gives 1
(36)2 * 1
(3)6×2 * 1
312 * 1
312
Thus, the total number of candies in the store is 312.

some aspects of the spline smoothing approach to non-parametric regression curve fitting (with discussion).
Regression without parameters using smoothing splines A scatterplot's data is smoothed by fitting a smooth curve to it. Will initially concentrate on two variable issues: OneX Yand Will eventually include more than two predictors. Our example: Where "1; "1;::: "are independent from me," yi=f(xi) + I.
What is a non-parametric regression?The appealing, adaptable, and widely-used method of non-parametric regression uses cubic splines for curve estimation. Although the fundamental concept was developed many years ago, the approach is maybe not as well recognized or used as it could be. This paper's topics and examples are meant to increase comprehension and broaden the applicability of the spline smoothing technology. The fundamentals of the method, its relationship with moving averages and other smoothing techniques, the automatic selection of the degree of smoothing, and the use of residuals for model adaption and diagnostic testing are just a few of the specific topics covered. A finite-dimensional Bayesian framework is used to address the issue of offering inference areas for curves and for pertinent curve attributes.

NO , this fact does not indicate that there was bias in the selection process and that the selection process was not random.
This fact does not indicate that there was bias in the selection process and that the selection process was not random unless we know the number of different subject majors among the thirty volunteers.
It is possible that out of 30 volunteers , 20 can be from music majors and the rest 10 are majors from other subjects.
so in this case it is possibility for the process to be random and for the three students in the committee to all end up being music majors.

According to the given information The highest 10% of the population's IQ is 0.0179.
Describing Standard deviation:The root of the variability in the given group as well as ungrouped data is referred to as the standard deviation. The standardized value is the value left after subtracting the mean and dividing by the standard deviation.
z = (x- μ) / σ
x denotes the observations (a specific value that you are calculating the z-score for).
Mu(μ) is the mean.
Sigma(σ) denotes the standard deviation.
According to the given data:x = 131.5
μ = 200

What do you mean by factorization in polynomial?Factorization of polynomials, also known as polynomial factorization, is a mathematical and computer algebraic technique that combines irreducible factors with coefficients in the same domain to produce a polynomial with coefficients in a particular field or in integers. A polynomial with coefficients in a certain field or in integers is expressed as the product of irreducible factors with coefficients in the same domain in mathematics and computer algebra, which is known as polynomial factorization. A polynomial can be expressed as the product of its factors, where the components must have a degree that is less than or equal to the original polynomial.
The equation is given as:
x^2 + 2 x - 48 = 0
Expand the equation
x^2 + 8x - 6x - 48 = 0
Factorize the equation
x(x + 8)- 6(x + 8)
Factor out x + 2
(x + 8)(x - 6) = 0

To make a small vase, Elisa uses no more than 4.5 ounces of clay. To make a large vase, she uses at least 12 ounces of clay. Which compound inequality represents the number of ounces of clay, c, that Elisa uses to make one vase of either size? 4.5 < c < 12 4.5 ≤ c ≤ 12 c < 4.5 or c > 12 c ≤ 4.5 or c ≥ 12
The compound inequality that represents the number of ounces of clay, "c", Elisa uses to make one vase of either size is [(c ≤ 4.5) or (c ≥ 12)].
As per the question statement, Elisa uses no more than 4.5 ounces of clay to make a small vase and at least 12 ounces of clay to make a large vase.
We are required to find out the compound inequality that represents the number of ounces of clay, that she uses to make one vase of either size.
Let the number of ounces of clay, that Elisa uses to make one vase of either size be denoted by "c".
Since, Elisa uses no more than 4.5 ounces of clay to make a small vase, The words "no more than" implies maximum, i.e., "either less than or equals to" and hence, for a small vase, "c" must be less than or equal to 4.5 oz, which gives [tex](c \leq 4.5)[/tex] ...(1)
On the other hand, to make a large vase, she uses at least 12 ounces of clay where the words "at least" means minimum, i.e, "either more than or equals to" and hence, for a large vase,
Thus "c" is more than or equal to 12 oz, which gives [tex](c \geq 12)[/tex]...(2)
Now, combining (1) and (2), we get [(c ≤ 4.5) or (c ≥ 12)] which is option "d".

sin A = cos(90 - A)
Therefore,
cos (A + 20) = cos(90 - A)
divide both sides by cos
Hence,
A + 20 = 90 - A
A + A = 90 - 20
2A = 70

5. Which equation's line is steeper and explain how you know
A. y = 3x + 7
B. y=x+9
Answer:
Step-by-step explanation:
A, because the slope 3 is larger than a slope of 1.
Equation A's line is steeper than equation B's line because it has a higher slope.
To determine which equation's line is steeper, we need to compare their slopes. In both equations, the coefficients of the x term represent the slope of the line.
Let's first rewrite both equations in slope-intercept form, which is of the form y = mx + b, where "m" is the slope and "b" is the y-intercept:
A. y = 3x + 7
B. y = x + 9
In equation A, the coefficient of x is 3, which means the slope of the line is 3.
In equation B, the coefficient of x is 1, which means the slope of the line is 1.
Now, to compare the slopes, we can see that the slope of equation A (3) is greater than the slope of equation B (1).
This means that the line represented by equation A is steeper than the line represented by equation B.
Hence, equation A's line is steeper than equation B's line because it has a higher slope.

The solution for x and y for the given expression are :
x =1/2y + −1/2 and y=2x+1 respectively.
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, the given equation is : 16x + 9 = 9y - 2x
Now,
solving for x :
16x+9=9y−2x (Add 2x to both sides.)
16x+9+2x=−2x+9y+2x
18x+9=9y
18x+9+−9=9y+−9 (Add -9 to both sides)
18x=9y−9
18x/18 = 9y−9/18 (Divide both sides by 18.)
x =1/2y + −1/2
solving for y :
16x+9=9y−2x
−2x+9y=16x+9 (Flip the equation.)
−2x+9y+2x=16x+9+2x (Add 2x to both sides.)
9y=18x+9
9y/9=18x+9/9 ( Divide both sides by 9.)
y=2x+1
Therefore, the solution for x and y for the given expression are :
x =1/2y + −1/2 and y=2x+1 respectively.
