The equation of the linear function in slope intercept form is;

y = -0.5x + (-5)

The equation of a line in slope intercept form is expressed as;

y = mx + c

where;

m is slope

c is y-intercept

From the given table, we can see that the slope is;

m = (y2 - y1)/(x2 - x1)

m = (-4.5 - (-4))/(-1 - (-2))

m = -0.5/1

m = -0.5

At x = 0, y = -5 and so the y-intercept is -5. Thus the equation is;

y = -0.5x + (-5)

We need to calculate the total  of the rectangular prism and divide it with the volume of single 1/3 cubes to get the number of cubes. It takes almost 25 cubes to fill the rectangular prism of given dimension.

The rectangular prism has 2.5 m length, 5 m tall and 0.75 m wide.

The total volume of the rectangular prism will be 2.5 m × 5 m × 0.75 m = 8.25 m³.

The volume of single cube will be (1/3) m³ = 0.33 m³

Now to find the number of cubes to fill the rectangular prism, we can divide the volume of the prism with the volume of single cube.

8.25 m³ / 0.33 m³ = 25 cubes.

The Number of sodas sold: 174,

The number of hot dogs sold: 58.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given a vendor sold a combined total of 232 sodas and hot dogs.

let S for the number of sodas sold and H for the number of hot dogs sold,

S + H = 232

The number of sodas sold was three times the number of hot dogs sold

S = 3H

substitute the values,

S + H = 232

3H + H = 232

4H = 232

H = 232/4

H = 58

and the number of sodas sold

S = 3H

S = 3*58

To construct and interpret 95% confidence intervals for the outcomes of each simulation, then option C. The confidence interval from the first simulation is (0.564, 0.616), and the confidence interval from the second simulation is (0.615, 0.665). For the first trial, we are 95% confident the true proportion of wins with the new game strategy is between 0.564 and 0.616. For the second trial, we are 95% confident the true proportion of wins with the new game strategy is between 0.615 and 0.665 is correct.

To calculate the confidence interval, we can use the formula for a normal approximation to the binomial distribution.

The standard error of the proportion is given by the formula SE = sqrt(p(1-p)/n), where p is the proportion of wins, and n is the number of games played. The 95% confidence interval is given by p +/- 1.96 * SE.

Plugging in the values from the first simulation, we have p = 590/1000 = 0.59, and n = 1000. So, SE = sqrt(0.59(1-0.59)/1000) = 0.0242. The 95% confidence interval is 0.59 +/- 1.96 * 0.0242 = (0.564, 0.616).

Similarly, for the second simulation, p = 640/1000 = 0.64, and n = 1000. So, SE = sqrt(0.64(1-0.64)/1000) = 0.0244. The 95% confidence interval is 0.64 +/- 1.96 * 0.0244 = (0.615, 0.665).

To prove that two triangles are similar, we must show that they have the same shape, but not necessarily the same size. This can be done by showing that the corresponding angles of the two triangles are equal and that the corresponding sides are in proportion.

To do this, we can use the Side-Side-Side (SSS) Similarity Theorem. This theorem states that if all three pairs of corresponding sides of two triangles are in proportion, then the two triangles are similar. To prove this, we must show that the ratio of each pair of corresponding sides is equal.

For example, let's say we have two triangles ABC and DEF. To prove that these two triangles are similar, we must show that the ratio of AB to DE is equal to the ratio of BC to EF. We can do this by solving the following equation:

AB/DE = BC/EF

If the equation is true, then the two triangles are similar.

We can also use the Angle-Angle-Angle (AAA) Similarity Theorem to prove that two triangles are similar. This theorem states that if all three pairs of corresponding angles of two triangles are equal, then the two triangles are similar. To prove this, we must show that the measure of each pair of corresponding angles is equal.

For example, let's say we have two triangles ABC and DEF. To prove that these two triangles are similar, we must show that the measure of angle A is equal to the measure of angle D, the measure of angle B is equal to the measure of angle E, and the measure of angle C is equal to the measure of angle F.

If the measures of the corresponding angles are equal, then the two triangles are similar.

Therefore, to prove that two triangles are similar, we must show that either the corresponding sides are in proportion (using the SSS Similarity Theorem) or the corresponding angles are equal (using the AAA Similarity Theorem).

A child's ticket cost is  $12.50 and an adult's ticket cost $25.00.

Two or more expressions with an Equal sign is called as Equation.

Given that Mr and Mrs Tan and their three children bought tickets for a 'Holiday- On-Ice' show.

Let x be the cost of a child's ticket, 2x be the cost of adult's ticket

The cost of all three children's tickets would be 3x and total cost of Mr. and Mrs. Tan's tickets would be 4x

So the total cost of all five tickets would be 3x + 4x = 7x.

We know that the total cost was $87.50

7x = 87.50

Divide both sides by 7

x = 87.50 / 7

x=12.50

Taking into account the definition of a system of linear equations, Celia has 58 coins in her bank, 13 dimes and 45 quarters.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

In the systems of equations, the values of the unknowns must be found, with which, when replaced, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

You know:

So, the system of equations to be solved is

d + q= 58

0.10d + 0.25q= 12.55

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, Isolating the variable "d" from the first equation, we obtain:

d= 58 -q

Substituting in the second equation you get:

0.10× (58-q) + 0.25q= 12.55

Solving:

0.10×58 - 0.10q + 0.25q= 12.55

5.8 - 0.10q + 0.25q= 12.55

- 0.10q + 0.25q= 12.55 -5.8

0.15q= 6.75

q= 6.75÷ 0.15

q= 45

Remembering that d=58 - q, you get:

d= 58 - 45

d= 13

A 90% confidence interval based on a sample of size 200 would be more reliable than the original 90% interval.

This is because the larger sample size gives the interval a larger margin of error, meaning the interval is more likely to contain the true population means. This is due to the greater number of data points used to calculate the mean, which reduces the possibility of outliers skewing the results.

Additionally, the larger sample size increases the power of the test, meaning that the probability of getting a statistically significant result is increased. Therefore, the 90% confidence interval based on a sample of size 200 would be more reliable than the original 90% interval.
