-7 * -8 = 7 * 8

-7 * -8 = 56

7 * 8 = 56

56 = 56

Answer: YES they are equivalent/equal to each other because both of them equal positive 56.

• It wouldn’t be equivalent if one is a negative number and the other one is positive (even when it looks like the same number). If both numbers are positives / negatives with the same number then they’ll most likely be equivalent/equal to each other!

Step-by-step explanation:

The solution contains 68.7 milliliters of acid, according to the data provided.

An acid is any substance that tastes sour in water, turns blue litmus paper red, combines with some metals to free hydrogen, reacts without bases to form salts, and facilitates chemical reactions (acid catalysis).

Count the hydrogens in each component both before and after the reaction to determine if it is an acid or a basic. If the amount of hydrogens has reduced, that material seems to be the acid (which donates hydrogen ions).

Solution = 356 milliliters

Acid = 19.3% of solution

The amount of acid in the solution is calculated as:

Acid = 19.3% × 356 milliliters

Evaluate

Acid = 68.708 milliliters

Acid = 68.7 milliliters

The solution contains 68.7 milliliters of acid, according to the data provided.

It's {2} since it's the common between A and B

Answer: 12%

Step-by-step explanation:

Since we are given the information that at a school carnival, that 3 out of 25 tickets sold were early-admission tickets, to calculate the percentage of the tickets that were early-admission tickets goes thus:

= Number of early admission tickets / Total number of tickets × 100

= 3/25 × 100

= 12%

Therefore, the percentage of the tickets were early-admission tickets is 12%.

The mean squared error formula is:

\(MSE=\frac{\sum (y_i-\bar{y})^2}{n}\)

where, MSE is the mean squared error

\(y_i\) - observed values

\(\bar{y}\) - the predicted values

n - the number of data points

We know that in statistics the mean squared error tells us that whether or not a regression line is an accurate model for predicting data points in a particular set of data.

If the mean squared error value is minimum then it indicates an accurate regression model, or, goodness of fit.

The mean square error is calculated by taking the average of errors squared from data.

The formula for the mean squared error is:

\(MSE=\frac{\sum (y_i-\bar{y})^2}{n}\)

where, MSE is the mean squared error

\(y_i\) represents observed values

\(\bar{y}\) represents the predicted values

n represents the number of data points

There are 240240 possible permutations of choosing 5 shows from 14 available shows. It can be obtained by applying the formula of permutation.

What is permutation?

In mathematics, it is the number of ways in which given number of items can be arranged in different orders.

Here, we need to select 5 iteams from the given 14 iteams.

\(P(14,5)=\frac{14!}{(14-5)!}\\=\frac{14!}{(9!)}\\=\frac{(14)(13)(12)(11)(10)(9!)}{(9!)}\\=(14)(13)(12)(11)(10)\\=240240\)

Answer:

a) 22 batches

c) 7.3 batches

Step-by-step explanation:

a) It takes 0.25 cup of sugar to make a batch of chocolate chip cookies. I have 5.50 cups of sugar. How many batches of cookies can I make?

0.25 cup = 1 batch

5.5 cup = x

Cross Multiply

0.25 cup × x = 5.5 cup × 1 batch

x = 5.5 cup × 1 batch/0.25 cup

x = 22

Answer:

In A: y is a 25% decrease of x

In B: y is a 25% increase of x

Step-by-sep explanation:

For A:

The diagram in A shows that x = 4, while y = 3.

Thus, this means that y decreased by 1, relative to x.

The percentage decease would be:

\( \frac{1}{4} \times 100 \)

\( \frac{100}{4} = 25 \)

Therefore, y is a 25% decrease of x.

For B:

The diagram for B shows that x = 4, while y = 5.

Thus, this means that y increased by 1, relative to x.

The percentage increase would be:

\( \frac{1}{4} \times 100 \)

\( \frac{100}{4} = 25 \)

Therefore, y is a 25% increase of x.

Answer:

Step-by-step explanation:

A- Y is a decrease.

1/4 x 100 = 100/4 =25%

25% and decrease.

B- Y is a increase

1/4 x 100 = 100/4=25%

25% and increase.

The stream velocity has no influence on the amount of dissolved load it contains. The amount of dissolved material depends on erosion and deposition carried out in the watercourse. These are affected by factors such as the slope of the land, the resistance of the material to erosion, the size of the sediments transported, etc.

Stream velocity plays an important role in the transport of sediments and dissolved loads in a watercourse. It affects the erosion and deposition processes that occur in the watercourse, which in turn affect the amount of sediment and dissolved load that is carried by the stream. For example, faster stream velocities can cause more erosion of the stream bed, leading to more material being carried in the water.

Sediment is any particulate matter that is transported by a fluid, and it can come in many different forms. The three main types of sediment are:

Answer:

Step-by-step explanation:

A, the measures of variation would all be 0. This is because variation measures the differences or spread of values within a dataset. If there is no mercury present in the tuna sushi, then all the values would be the same, resulting in no variation and all measures of variation would be 0.

that since there is no difference or spread in the data, it is not possible to calculate the range, variance, or standard deviation, which are the measures of variation. Therefore, the correct answer is option A.

In conclusion, if the tuna sushi contained no mercury, the measures of variation would all be 0, as there would be no variation in the data.

The measures of variation describe the dispersion or spread of a dataset. If the tuna sushi contained no mercury, that means there is no variation in mercury content. In this case, all data points would be the same (0 mercury), resulting in no dispersion or spread.

If tuna sushi had no mercury content, the measures of variation would be 0, indicating no dispersion in the data.

Answer:

Step-by-step explanation:

x^3 = 1,000,000  Find the cube root of 1,000,000

x^3 = 1.0x10^6     Using scientific notation, we can split the 1,000,000 into a 1.0 and a factor of 10*10*10*10*10*10 or 10^6

x = 1.0x10^2         The cube root of 1.0 is 1.0.  The cube root of 10^6 is found by dividing the exponent by 3:  10^2

The cube root of 1,000,000 is 1.0X10^2, or 100.

x = 100

⇒ x² - 6x = -8

\(\sf add \ 9 \ on \ both \ sides\)

⇒ x² - 6x + 9 = -8 + 9

\(\sf simplify \ and \ complete \ square\)

⇒ x² - 3x - 3x + 9 = 1

\(\sf factor \ common \ term\)

⇒ x(x - 3) - 3(x - 3) = 1

\(\sf collect \ into \ groups\)

⇒ (x - 3)² = 1

\(\sf square \ root \ both \ sides\)

⇒ x - 3 = ±√1

\(\sf simplify\)

⇒ x - 3 = ±1

\(\sf change \ side\)

⇒ x = 1 + 3, -1 + 3

\(\sf simplify\)

⇒ x = 4, 2

\(\rightarrow \sf 4x^2 + 12x + 11 = 0\)

\(\rightarrow \sf 4\left(x^2+3x+\dfrac{11}{4}\right) = 0\)

\(\rightarrow \sf 4\left(x^2+3x+\dfrac{11}{4}+\left(\dfrac{3}{2}\right)^2-\left(\dfrac{3}{2}\right)^2\right) = 0\)

\(\rightarrow \sf 4\left(x+\dfrac{3}{2}\right)^2+2 = 0\)

\(\rightarrow \sf \left(x+\dfrac{3}{2}\right)^2 = -\dfrac{2}{4}\)

\(\rightarrow \sf \left(x+\dfrac{3}{2}\right)^2 = -\dfrac{1}{2}\)

\(\rightarrow \sf x+\dfrac{3}{2} = \pm \sqrt{-\dfrac{1}{2} }\)

\(\rightarrow \sf x+\dfrac{3}{2} = \pm i\sqrt{\dfrac{1}{2} }\)
