Answer:

1,124.49

Step-by-step explanation:

Answer:

1000 + 100 + 20 + 4 + 0.4 + 0.09

Step-by-step explanation:

The solution to this system of equations are x = -2 and y = 4.

In order to determine the solution to a system of two linear equations, we would have to evaluate and eliminate each of the variables one after the other, especially by selecting a pair of linear equations at each step and then applying the elimination method.

Given the following system of linear equations:

-4x + 2y = 16                .........equation 1.

4x+8y = 24                 .........equation 2.

By adding equation 2 to equation 1, we have:

10y = 40

y = 40/10

y = 4.

For the value of x, we have:

-4x + 2(4) = 16

-4x = 16 - 8

x = -2.

Answer:

1. Mean : 85.6

2. Median : 90

3. Mode : 95

4. Range : 35

Step-by-step explanation:

1. For Mean, you add up all the terms and divide the resulting sum by the number of terms. In this case there were 9 terms that added up to 770, and when you divided that result by 9, the answer was 85.555 repeating. Since the question asks to round to the nearest tenth 85.6 represents the correct mean or average of the class.

2. To find the median, line up all the numbers in order from least to greatest. Like so :

60,75,75,90,90,95,95,95,95

In order to find the median, find the middle term. Since there are 9 terms, the middle term will be the fifth one. In this case, the answer was 90.

3. Mode represents the number that appears the most in a data set. Look at the 9 terms and find the one that appears the most. In this case it is 90.

4. Lastly, to find the range, subtract the lowest value in the data set from the highest one. 95 is the highest and 60 is the lowest. Do \(95-60\) and you will get an answer of 35.

Hope this helps!

Answer:

Mean: 85.6

Median: 90

Mode: 95

Range: 35

Step-by-step explanation:

Mean: Add up all the value and divide by the number of values you have.

75 + 95 + 90 + 95 + 60 + 95 + 75 + 95 + 90 = 770

770 / 9 = 85.6

Median: Rearrange in increasing order + look at middle number

60, 75, 75, 90, 90, 95, 95, 95, 95

Mode: Number that shows up the most.

95 shows up 4 times.

Range: Maximum - Minimum.

95 - 60 = 35.

Substituting the given values in the formula, the standard deviation (or standard error) of the sampling distribution of the difference between the two sample proportions is 0.04.

The standard deviation or standard error of the sampling distribution of the difference between two sample proportions is given by the formula as,

σp1 - p2 = √{ [P1(1 - P1)] / n1 + [P2(1 - P2)] / n2 },

where P1 and P2 are the sample proportions, n1 and n2 are the sample sizes, and σp1 - p2 is the standard deviation (or standard error) of the sampling distribution of the difference between the two sample proportions.

Therefore, substituting the given values in the formula, we get,

σp1 - p2 = √{ [0.67(1 - 0.67)] / 200 + [0.73(1 - 0.73)] / 400 }

σp1 - p2 = √{ [0.22 / 200] + [0.1974 / 400] }

σp1 - p2 = √{ 0.0011 + 0.0005 }

σp1 - p2 = √0.0016

σp1 - p2 = 0.04

Therefore, substituting the given values in the formula, the standard deviation (or standard error) of the sampling distribution of the difference between the two sample proportions is 0.04.

Answer:

Wrong values are plotted in the question statement graph.

Please find correct graph.

Step-by-step explanation:

Given that:

\(y =x+3\) and \(-1<x<5\)

i.e. we can put a value of x in the equation which is greater than -1 and lesser than 5.

OR

we can say, the points where x = -1 and x = 5 will not be included in the graph (they will be shown as hollow circle).

Now, let us put the values one by one:

x = -1, y = -1 + 3 =2

x = 0, y = 0 + 3 = 3

x = 1, y = 1 + 3 = 4

x = 2, y = 2 + 3 = 5

x = 3, y = 3 + 3 = 6

x = 4, y = 4 + 3 = 7

x = 5, y = 5 + 3 = 8

Therefore, the table of values become:

\(\begin{center}\begin{tabular}{ c c } x & y\\ -1 & 2\\ 0 & 3 \\ 1 & 4 \\ 2 & 5 \\ 3 & 6 \\ 4 & 7 \\5 & 8\\\end{tabular}\end{center}\)

Points (-1, 2) and (5, 8) will not be included in the graph.

Answer:

A, 152 cm.

Step-by-step explanation:

A rectangular pyramid has a volume equation of

V = (lwh)/3.

Therefore, when we plug the values in:

[(7)(5)(13)]/3 = V

V = 455/3

V = 151.666667

V is approximately equal to 152 cm^3.

opposit side of parallelogram are equal and opposit angles are also equal

The triangle that has the coordinates as A(0,-4) B(0,-9) C(-2,-5) is; A scalene Triangle

The formula for the distance between two coordinates is;

D = √[(y₂ - y₁)² + (x₂ - x₁)²]

Thus;

Distance AB = √[(-9 + 4)² + (0 - 0)²]

Distance AB = √25

Distance AB = 5

Distance BC = √[(-5 + 9)² + (-2 - 0)²]

Distance BC = √20

Distance CA = √[(-4 + 5)² + (-2 - 0)²]

Distance CA = √5

Since the three sides all have different lengths, then they the triangle is said to be a scalene triangle.

To answer this given question, we will make use of the Empirical rule of normal distribution

The Empirical Rule states that 99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean. Under this rule, 68% of the data falls within one standard deviation, 95% percent within two standard deviations, and 99.7% within three standard deviations from the mean.

The image below helps gives a clearer understanding

So in our case, since the mean is 189 mg/dL and the standard deviation is 23

So on solving the provided question, we can say that here in the quadrilateral; angle MJL = angle JLK = 60

A quadrilateral is a four-sided polygon in geometry that has four edges and four corners. The word is a derivative of the Latin words quadri and latus (meaning "side"). Having four sides, four vertices, and four corners, a rectangle is a two-dimensional form. Concave and convex come in primarily two varieties. Additionally, there are several subclasses of convex quadrilaterals, including trapezoids, parallelograms, rectangles, rhombuses, and squares. Four straight sides make up a rectangle, which is a two-dimensional form. There are several different types of quadrilaterals, including parallelograms, trapezoids, rectangles, kites, squares, and rhombuses.

(a) The function f(x) = 4x³ - 2 is injective (one-to-one) and surjective (onto).

(b) The inverse function of f is f⁻¹(x) = ∛((x + 2)/4).

(a) To show that the function f: R → R defined by f(x) = 4x³ - 2 is injective (one-to-one) and surjective (onto):

Injectivity: Suppose we have two values x₁ and x₂ in the domain such that f(x₁) = f(x₂). We need to prove that x₁ = x₂. So, let's assume 4x₁³ - 2 = 4x₂³ - 2. By simplifying, we get 4x₁³ = 4x₂³.

Dividing both sides by 4 gives us x₁³ = x₂³.

Taking the cube root of both sides gives x₁ = x₂. Therefore, the function f is injective.

Surjectivity: For surjectivity, we need to show that for every y in the codomain (R), there exists at least one x in the domain (R) such that f(x) = y. Let's take an arbitrary y ∈ R.

We need to find an x such that f(x) = y. Solving the equation 4x³ - 2 = y for x, we have x = ∛((y + 2)/4). Thus, for any y in the codomain, there exists an x in the domain such that f(x) = y. Therefore, the function f is surjective.

(b) To find f⁻¹(x) (the inverse function of f), we interchange the roles of x and f(x) in the original function equation and solve for x.

Start with y = 4x³ - 2 and solve for x:

y + 2 = 4x³

x³ = (y + 2)/4

x = ∛((y + 2)/4)

Thus, the inverse function of f is f⁻¹(x) = ∛((x + 2)/4).

Answer:

\(y = -\frac{1}{2}x - 2.5\)

Step-by-step explanation:

If the second line is parallel, then we know that the slope must be the same. Therefore, the slope of the second equation must also be -1/2

Now, we can substitute the given values into the slope-intercept equation, and solve for the y-intercept, b, of the second equation:

\(y=mx+b\)

\(1 = (-\frac{1}{2})(-7) + b\)

\(1 = 3.5 + b\)

\(b = -2.5\)

Therefore, the equation of the second line should be:

\(y = -\frac{1}{2}x - 2.5\)

1&(1/2) or 1.5 or 3/2 cups flour needed for 36 cookies

Step-by-step explanation:

Flour : Cookie ratio (Flour needed to make particular cookie) = 1 : 24

1 cup flour make 24 cookies, so 1/2 cup floor make 12 (half) cookies.

So, 1&(1/2) or 1.5 or 3/2 cups would make 24 + 12, ie = 36 cookies

Multiplying numerator & denominator of fractional ratio 1 : 24 with 1.5 each

(1 x 1.5) : (24 x 1.5)

It implies 1.5 : 36 flour cookie ratio
