Consider the line that passes through the point P(-1,-1) and is parallel to the line x-y=7. Write the point slope equation of the line. Use exact values.​

Answer: A. 192 feet

Step-by-step explanation:

1 foot 4 inches=

1 foot+4 inches=

12 inches+4 inches=

16 inches

Hence,

16*12=

16*(10+2)=

(16)(10)+(16)(2)=

160+32

192 feet

The average cost for 16 gallons is $46.272

The first step is to calculate the price of one gallon

5= 14.46

1= x

cross multiply

5x= 14.46

x= 14.46/5

x= 2.892

The price of 16 gallons can be calculated as follows

= 16 × 2.892

= 46.272

Hence the price of 16 gallons is $46.272

The student is wrong in the steps of the factorization.

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

The above means that the factored equation of x^2 + 2x - 48 = 0 is (x + 8)(x - 6) = 0

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".

Answer:

279936j

Step-by-step explanation:

In any normal distribution, about 0.7 percent (0.7%) of the data are outliers.

An outlier is also referred to as anomalous data and it can be defined as a numerical value that is either unusually too small or large (big) in comparison with the overall pattern of the numerical values contained in a data set.

IQR is an abbreviation for interquartile range and it can be defined as a measure of the middle 50% of data values when they are ordered from lowest to highest.

Mathematically, interquartile range (IQR) is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):

IQR = Q₃ - Q₁ = 75th percentile - 25th percentile.

The 75th percentile is equal to x when z has a p-value of 0.75, therefore, z is equal to 0.675. Similarly, the 25th percentile is equal to x when z has a p-value of 0.25, therefore, z is equal to -0.675.

Based on the 1.5 × IQR rule for outliers, the lower and upper z-scores are given by:

Zl = -0.675 -1.5(IQR)

Zl = -0.675 -1.5(0.675 + 0.675)

Zl = -0.675 -1.5(1.35)

Zl = -0.675 - 2.025

Zl = -2.7

Zu = 0.675 + 1.5(IQR)

Zu = 0.675 + 1.5(0.675 + 0.675)

Zu = 0.675 + 1.5(1.35)

Zu = 0.675 + 2.025

Zu = 2.7

For the p-value, we have:

P(z<2.7) = 1 - 0.9965

P(z<2.7) = 0.0035.

For the percentage of outliers, we have:

Outliers = 2 × 0.0035 × 100

Outliers = 0.0070 × 100

Outliers = 0.7%.

In this context, we can reasonably infer and logically deduce that about 0.7 percent (0.7%) of the data are outliers in any normal distribution.

Answer: A central angle is an angle with its vertex at the center of the circle and its two sides are radii. The sum of all central angles in a circle 360 degrees. The degree of the arc formed by the endpoints of a central angle is equal to the degree of the central angle.

Step-by-step explanation:

Given that x = 8, y = 2, and z = 3, the equation 2x = 3yz is false.

An expression is a number, variable or the combination of both put together by operation symbols while an equation is a statement that shows that two expressions are equal and is separated by an equal sign "=".

To check if the equation 2x = 3yz is true when x = 8, y = 2, and z = 3, plug in or substitute the value of each variable to the equation and evaluate.

2x = 3yz

2(8) = 3(2)(3)

Since 16 is not equal to 18, the given values do not satisfy the equation, then the statement is not true.

Slope of line=0

Slope of line=[tex]\frac{y2-y1}{x2-x1}[/tex]

=[tex]\frac{-4+4}{11-7}[/tex] =[tex]\frac{0}{4}[/tex] =0

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) formulations of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively.

The ratio of the "vertical change" to the "horizontal change" between (any) two unique points on a line is used to compute the slope.A declining line has a negative "rise." The line might be useful, as determined by a road surveyor, or it might appear in a diagram that represents a road or a roof as a description or a design.

The slope's absolute value serves as a gauge for a line's steepness, incline, or grade. A steeper line is indicated by a slope with a higher absolute value. A line can be drawn in one of four directions: upward, downward, horizontal, or vertical.

area of recatangle= 4x^3(x^3+3x^2+2x) =4x^6+12x^5+8x^4

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.

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.

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.
