For 1 cup of blue paint, 1/4 cups of black paint is needed

The given parameters are

8 cups of blue paint needed for 2 cups of black paint

This means that

8 cups of blue paint needed = 2 cups of black paint

Divide both sides of the equation by 8

So, we have the following equation

8/8 cups of blue paint needed = 2/8 cups of black paint

Evaluate the quotient

So, we have the following equation

1 cup of blue paint needed = 1/4 cups of black paint

Hence, the amount of black paint is 1/4

Tina has two bags of counters. Bag A has 5 red and 3 blue. Bag B has 4 red and 5 blue. The probability that tina takes two blue counters in fraction is 15/72

Given parameters:

Bag A= 5 red + 3 blue

Bag B = 4 red + 5 blue

Hence,

Total counters in bag A = 5 +3 = 8

Total counters in bag B = 4 + 5 = 9

Now let determine the probability that she takes two blue counters

Probability =  3 /8 × 5 /9

Probability = 15 / 72

Therefore 15 / 72 is the probability that two blue was taken.

Domain of the given function yx-3x=3y-1 is ( -∞,3) ∪ (3,∞), {x|x [tex]\neq[/tex] 3}.

The dependent variable and the independent variable are the two types of variables used to define a function.

The domain of a function is a set of all possible values of x which is an independent variable. For example The domains of function f(x)=x² can be all real numbers.

Despite x=0, the domain of g(x)=1/x can contain any real number.

The input values to a function are referred to as domains, while the output values are referred to as the range. The data flow is as follows:

Domain → Function → Range

We are aware that the value of x is the function's domain. Therefore, the domain is ( -∞,3) ∪ (3,∞), {x|x [tex]\neq[/tex] 3} for the provided function.

The standard deviation (SD) of a sample proportion obtained when the sample size is 1,600 is equal to 0.0121.

A sample proportion can be defined as the proportion of individuals in a sample that have a specified characteristic or trait.

Mathematically, sample proportion can be calculated by using this formula:

[tex]\hat{p} = \frac{x}{n}[/tex]

Where:

In Mathematics, the standard deviation (SD) of a sample proportion obtained when the sample size is 1,600 can be calculated by using this formula:

Standard deviation (SD) = √(p(1 - p)/n)

Substituting the given parameters into the formula, we have;

Standard deviation (SD) = √(0.37(1 - 0.37)/1,600)

Standard deviation (SD) = √(0.37(0.63)/1,600)

Standard deviation (SD) = √(0.2331)/1,600)

Standard deviation (SD) = √0.0001457

11 dogs will eat 15 pounds of food.

According to the question,

We have the following information:

3 dogs eat 4 pounds.

We have to find how many dogs will eat 15 pounds.

We have the following expression:

4 pounds = 3 dogs

We can treat dog as a non-living object or a product.

So, we can find the parts devoted to 1 pound:

1 pound = 3/4

Now, we have to find the same for 15 pounds:

15 pounds = (3/4)*15

15 pounds = 11.25

Now, note that the number of dogs can not be in points. So, we will round it off to form a whole number.

So, 15 pounds = 11 dogs

Hence, 15 pounds of food is enough for 11 dogs.

The proportion of the generated values that fall inside the range of each histogram bar is used to compute the vertical scale. The standard deviation is an indicator of how much the values in the data set typically deviate from the mean.

It always displays the median and the middle 50% of the data. For data displayed in histograms, a similar spread measurement is helpful. The term for it is the standard deviation. The standard deviation is an indicator of how much the values in the data set typically deviate from the mean.

The proportion of the generated values that fall inside the range of each histogram bar is used to compute the vertical scale. The sum of the bar heights is therefore one. Only discrete variables (right), where the histogram heights now total to unity, are suitable for relative frequency analysis.

A measurement of how far points deviate from the mean is the standard deviation. The first histogram includes fewer points that are close to the mean and more points that are distant from the mean (scores of 0, 1, 9, and 10). (scores of 4, 5 and 6). As a result, its standard deviation will be higher.

The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship between a component and a whole in which the value of the whole is always assumed to be 100.

Given that : A toy store is having a sale on puzzles. For each puzzle, Naomi buys she gets 75% off of a second puzzle. The original price of each puzzle is $16.50. Naomi bought 4 puzzles

The equation is true when x = 2.25

Explanation:

On the left side of the equation, there are 3 triangles with value -x and 10 triangles with value 1. So, the expression for the left side of the equation is:

3*(-x) + 10*(1)

-3x + 10

For the right side, we have 5 triangles with value x and 8 triangles with value -1. So, the expression for the right side is:

5*x + 8*(-1)

5x - 8

Now, we can write the equation as:

-3x + 10 = 5x - 8

So, solving for x, we get:

-3x + 10 + 3x = 5x - 8 + 3x

10 = 8x - 8

10 + 8 = 8x - 8 + 8

18 = 8x

18/8 = x

2.25 = x

Therefore, the equation is true when x is equal to 2.25
