SOLUTION:

Step 1 ;

In this question, we are meant to select TWO options that have pairs of variables that exhibit linear relationships.

By definition,

The linear relationship between two variables is positive when both increase together; in other words, as values get larger, values get larger.

This is also known as a direct relationship.

The linear relationship between two variables is negative when one increases as the other decreases.

Step 2 :

The TWO options are:

OPTION A - side length and perimeter of 1 face

OPTION D - Area of 1 face and surface area.

The in the canoe race, Dallas paddles faster than Mason.

According to the statement

We have to find that the Speed of the .

So, For this purpose, we know that the

The rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered.

From the given information:

Mason and Dallas are in a canoe race. Mason paddles 7/8 mile in 1/4. Dallas paddles 9/5 miles in 1/3 hour.

Then

The Mason paddles 7/8 mile in 1/4 hour.

We calculate the Speed = Distance/Time

Speed = (7/8)/(1/4)

Speed = (7/8) × (4/1)

Speed = 7/2

Speed = 3.5 miles per hour

And Dallas paddles 9/5 miles in 1/3 hour.

Speed = Distance/Time

Speed = (9/5)/(1/3)

Speed = (9/5) × (3/1)

Speed = 27/5

Speed = 5.4 miles per hour.

So, The in the canoe race, Dallas paddles faster than Mason.

Answer:

Step-by-step explanation:

The total mass of the alloy is the sum of the masses of the two metals:

mass = density x volume = (8800 kg/m³ x 15 m³) + 850 kg = 132,000 kg + 850 kg = 132,850 kg

The total volume of the alloy is the sum of the volumes of the two metals:

volume = 15 m³ + 6.2 m³ = 21.2 m³

Therefore, the density of the alloy is:

density = mass / volume = 132,850 kg / 21.2 m³ ≈ 6266 kg/m³

Rounding to the nearest integer, the density of the alloy is 6266 kg/m³.

The correct statement regarding the transformation is given as follows:

Dilation bu a scale factor of 0.5 about the origin. Then reflect over the x-axis.

The true statements about the dilation are given as follows:

A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.

For this problem, the coordinates of the dilated line segment are half the coordinates of the original line segment, hence the scale factor is given as follows:

k = 0.5.

The y-coordinate then has the signal exchange, hence the figure is also reflected over the x-axis.

The probability is given by -0.001, that the mean of the sample would differ from the population mean by less than 0.9 watts.

What is normal probability distribution?

Normal distribution also known as the Gaussian probability, ia a probability distribution that is symmetric about the mean, showing that data bear the mean are more frequent in occurrence than data far from the mean.

In a set with mean μ and standard deviation (which is the square root of the variance) σ , the z score of a measure X is given by:

Z =X-μ/σ

we have given μ =129

σ = \(\sqrt{100}\) n = 96

This is the pvalue of Z when X = 129+1.7 =130.7 subtracted by the pvalue of Z when X = 129 - 1.7 = 127.3

When X = 130.7

Z =X-μ/σ

Z = 130.7-129/10

Z = 0.17  pvalue = 0.1699

When X = 127.3

Z =X-μ/σ

Z = 127.3-129/10

=-0.17 pvalue

0.1699 - 0.1700 = -0.001

Hence the probability is -0.001

Answer:

q=8/3

Step-by-step explanation:

First, add 5/6 to both sides to get rid of -5/6 to get q=16/6 then simplify to q=8/3.

Answer:

\(q=2\frac{2}{3}\)

Step-by-step explanation:

The given equation consists of a fraction and a mixed number.

First, convert the mixed number into an improper fraction by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:

\(q-\dfrac{5}{6}=1 \frac{5}{6}\)

\(q-\dfrac{5}{6}=\dfrac{1 \cdot 6+5}{6}\)

\(q-\dfrac{5}{6}=\dfrac{11}{6}\)

Now, add 5/6 to both sides of the equation to isolate q:

\(q-\dfrac{5}{6}+\dfrac{5}{6}=\dfrac{11}{6}+\dfrac{5}{6}\)

\(q=\dfrac{11}{6}+\dfrac{5}{6}\)

As the fractions have the same denominator, we can carry out the addition by simply adding the numerators:

\(q=\dfrac{11+5}{6}\)

\(q=\dfrac{16}{6}\)

Reduce the improper fraction to its simplest form by dividing the numerator and denominator by the greatest common factor (GCF).  

The GCF of 16 and 6 is 2, therefore:

\(q=\dfrac{16\div 2}{6 \div 2}\)

\(q=\dfrac{8}{3}\)

Finally, convert the improper fraction into a mixed number by dividing the numerator by the denominator:

\(q=2 \; \textsf{remainder}\;2\)

The mixed number answer is the whole number and the remainder divided by the denominator:

\(q=2\frac{2}{3}\)

The Propositions are resulting

(a) ∀x∃y(x = y²) is False

(b) ∀x∃y(x² = y) is True.

(c) ∃x∀y(xy = 0) is True.

(d) ∀x∃y(x + y = 1) is True.

(a) ∀x∃y(x = y²)

This proposition states that for every x, there exists a y such that x is equal to y². To determine the truth value, we need to check if this statement holds true for every value of x.

If we take any positive value for x, we can find a corresponding value of y that satisfies the equation.

For example, if x = 4, then y = 2 satisfies the equation since 4 = 2². Similarly, if x = 9, then y = 3 satisfies the equation since 9 = 3².

Therefore, the proposition (a) is false.

(b) ∀x∃y(x² = y)

For any given positive or negative value of x, we can find a corresponding value of y that satisfies the equation.

For example, if x = 4, then y = 2 satisfies the equation since 4² = 2. Similarly, if x = -4, then y = -2 satisfies the equation since (-4)² = -2.

Therefore, the proposition (b) is true.

(c) ∃x∀y(xy = 0)

The equation xy = 0 can only be satisfied if x = 0, regardless of the value of y. Therefore, there exists an x (x = 0) that makes the equation true for every y.

Therefore, the proposition (c) is true.

(d) ∀x∃y(x + y = 1)

To determine the truth value, we need to check if this statement holds true for every value of x.

If we take any value of x, we can find a corresponding value of y that satisfies the equation.

For example, if x = 2, then y = -1 satisfies the equation since 2 + (-1) = 1. Similarly, if x = 0, then y = 1 satisfies the equation since 0 + 1 = 1.

Therefore, the proposition (d) is true.

What do you mean by co interior angle?

Co interior angles are interior angles that add up to 180 degrees. This means that the sum of the two interior angles on the same side of the horizontal side are complementary. The interior angles of Co are similar to the shape of a 'C' and both angles are unequal.

Common interior angles are also called continuous interior angles or equilateral interior angles.

In the given figure, line a is parallel to line b. Therefore, these two angles are co interior angle and sum of co interior angle is 180 degree

2x + 5 + 8x + 5 = 180 degree

10x + 10 = 180 degree

10x = 180 - 10

10x = 170

x = 170/10 = 17

Therefore, x = 17

a. To sketch the graph of the function F = 9/5 C + 32, we can plot a few points and connect them with a straight line.

For example, when C = 0, F = 32, so we can plot the point (0, 32).  When C = 100, F = 212, so we can plot the point (100, 212). Connecting these two points gives us the following graph

b. The slope of the graph is 9/5. This represents the rate of change of F with respect to C. Specifically, it means that for every 1 degree Celsius increase in temperature, there is a corresponding increase of 9/5 degrees Fahrenheit.

c. The F-intercept is 32. This represents the Fahrenheit temperature when the Celsius temperature is 0. In other words, it is the point where the graph crosses the y-axis.

To determine the function that models the data, we need to analyze the relationship between the cost per photo and the number of photos a customer buys. From the given information, we can observe that the cost per photo varies inversely with the number of photos. This implies that as the number of photos increases, the cost per photo decreases, and vice versa.

To model this relationship, we can use the inverse variation equation, which can be expressed as:

y = k/x

Here, y represents the cost per photo, x represents the number of photos, and k is the constant of variation.

Let's examine the data given in the table to find the value of k:

Number of Photos (x) Cost per Photo (y)

10 10

25 4

50 2

100 1

We can see that as the number of photos increases, the cost per photo decreases. We can use any pair of values from the table to solve for k. Let's choose the pair (50, 2):

2 = k/50

Solving for k:

k = 2 * 50 = 100

Now that we have the value of k, we can write the function that models the data:

y = 100/x

Therefore, the function that models the data is y = 100/x, where y represents the cost per photo and x represents the number of photos a customer buys.
