An equation is y = -12/3 when x = 3, y = -4.

What is equation?

An equation is a mathematical statement that indicates that two expressions are equal to each other. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Equations are used to solve problems and find the value of unknown variables that satisfy the given conditions.

If x and y vary inversely, it means that as x increases, y decreases and vice versa. We can write this relationship as:

x × y = k

where k is a constant of proportionality. To find the value of k, we can use the given information.

When x = 3, y = -4:

3 × (-4) = k

k = -12

Now we can substitute k into the equation to get:

x × y = -12

This is the equation relating x and y. To find y when x = 3:

3 × y = -12

y = -12/3

Therefore, when x = 3, y = -12/3.

-5/4 - x = -1

value of x is -1/4

Answer: i= -6

Step-by-step explanation:

first, you want to separate the constants(Normal numbers that do NOT have i or a letter attached to them, in this case the 3 and the 8) from the -2i. To do this, you have to combine like terms first

3+8=11

Now you must subtract 11 from both sides of the equation,

11-11=0

23-11=12

you should be left with just -2i on one side, and 12 on the other side.

You now want i (the variable) by itself, so divide by the number attached to it (in this case, -2) do this for both sides.

-2i/-2= i

12/-2=-6

you are now left with your variable (i) equaling -6

(a) To compute the experimental probability of rolling a 1 or 6 from Latoya's results, we need to determine the number of times a 1 or 6 was rolled and divide it by the total number of rolls Latoya made.

Let's assume that Latoya rolled the dice 100 times and obtained 20 1's and 10 6's. The total number of successful outcomes (rolling a 1 or 6) is 20 + 10 = 30.

Therefore, the experimental probability of rolling a 1 or 6 is 30/100 = 0.3 or 30%.

(b) Assuming the cube is fair, the theoretical probability of rolling a 1 or 6 can be determined by considering the favorable outcomes (rolling a 1 or 6) divided by the total possible outcomes (rolling any number from 1 to 6).

Since there are two favorable outcomes (1 and 6) out of six possible outcomes (1, 2, 3, 4, 5, 6), the theoretical probability is 2/6 = 1/3 or approximately 0.3333.

(c) The correct statement is B. As the number of rolls increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal. This is due to the law of large numbers, which states that as more trials are conducted, the experimental probability tends to converge towards the theoretical probability. However, it is not necessary for them to be exactly equal. Random variations can cause some discrepancy, but with a larger number of rolls, the experimental probability should approach the theoretical probability more closely.

Using equation of proportionality, the unit rate of canine cakes is 1.5, for bark bits is 1.64 and for woofy waffles is 1.2

A unit rate is a rate in which the second quantity in a comparison is one unit. In other words, it is the rate per unit of the first quantity.

Unit rates are useful for making comparisons and for solving problems. For example, if you are comparing the prices of two similar products that come in different sizes, you can use the unit price to determine which product is a better value. The unit price is the price per unit of measurement, such as price per ounce, price per pound, or price per item.

To find the unit rate of the item, we can apply the concept of proportion here;

y = kx

k = constant of proportionality

For canine cakes

24 = 16k

k = 24/16 = 1.5

We can solve for bark bits

82 = 50k

k = 82/50

k = 1.64

And for woofy waffles

48 = 40k

k = 48/40 = 1.2

The weighted average length of a nail from the carpenter's box whose distribution is give in image is: 3.5cm.

What is weighted average ?

Weighted average is a type of average that takes into account the relative importance or weight of each data point. In a weighted average, each data point is multiplied by a corresponding weight, which reflects its relative importance, and the products are then summed and divided by the sum of the weights.

To find the weighted average length of a nail, we need to multiply each nail length by its percent abundance, then add up all the products and divide by the total percent abundance.

Let's start by calculating the product of each nail length and its percent abundance:

Short nail: (2.5 cm) x (70.5%) = 1.7625 cm

Medium nail: (5.0 cm) x (19%) = 0.95 cm

Long nail: (7.5 cm) x (10.5%) = 0.7875 cm

Now, we add up all the products:

1.7625 cm + 0.95 cm + 0.7875 cm = 3.5 cm

Finally, we divide by the total percent abundance:

70.5% + 19.0% + 10.5% = 100%

Therefore, the weighted average length of a nail from the carpenter's box is: 3.5 cm ÷ 100% = 3.5cm

As per the given data, to enable the drain pipe to carry 60 liters per second, there needs to be a 66.67% increase in the diameter of the drain pipe.

We must comprehend the link between the carrying capacity and the area of the pipe's cross-section in order to calculate the percentage increase in the drain pipe's diameter required to make it capable of carrying 60 litres per second.

The cross-sectional area of the pipe directly relates to its carrying capacity. This implies that the carrying capacity will grow if the cross-section's area increases.

Q ∝ A

Q1/A1 = Q2/A2

A2 = (Q2/Q1) * A1

A2 = (60/36) * A1

A2 = (5/3) * A1

Percentage increase = (A2 - A1)/A1 * 100

Percentage increase = [(5/3) * A1 - A1]/A1 * 100

Percentage increase = (2/3) * 100

Percentage increase = 66.67%

Thus, the answer is 66.67%.
