Answer:

75/-3 = -25

Step-by-step explanation:

Numerator: -5^2 + 10^2 = 75

-5^2 = -25, since the minus sign is not in parentheses with the 5, it does not get squared so the negative is added on to five squared which is 25.

10^2 = 100,

-25 + 100 = 75

Denominator: (2 x (-5) x 3) + 3^3 = -3

2 x (-5) x 3 = -30, we can simply multiply these all together so 2 x -5 is -10, and -10 x 3 = -30

3^3 = 27, 3^3 = 3 x 3 x 3, which multiplied all together, 3 x 3 = 9, 9 x 3 = 27

-30 + 27 = -3

Total Fraction = 75/-3  

Simplified = -25

The amount of bucket that is filled is 2.25 gallons of water

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The total amount the bucket of water can hold = 5 gallons

The percentage of bucket that is full = 45 %

So ,

The amount of bucket of water that is full is =
percentage of bucket that is full x total amount the bucket of water can hold

The amount of bucket of water that is full is = ( 45 / 100 ) x 5

                                                                         = 0.45 x 5

                                                                         = 2.25 gallons

Hence , the amount of water that the bucket is filled is 2.25 gallons

Answer:

CB = 9

Step-by-step explanation:

To find CB, apply trigonometric function.

Reference angle = 60°

Hypotenuse = 18

Adjacent = CB

Apply CAH:

Cos 60 = Adj/Hyp

Cos 60 = CB/18

Cos 60 × 18 = CB

CB = Cos 60 × 18

CB = 9

What is a distribution?

A distribution includes an algebraic function that calculates the likelihood that long-been-considered outcomes will occur. In the perspective of its population space as well as event probability, it is a schematic representation of random phenomena.

To ascertain regardless of whether the observed sample frequency deviates noticeably from those given in the null hypothesis, should use the chi-square goodness of fit test.

He notes the number of tracks in each classification after listening to 100 songs selected at random while his player is in shuffle mode. One can determine out whether the quality of fit is "good enough" and draw the conclusion that the population matches the distribution by applying the chi-square goodness of fit test.

Answer:

Step-by-step explanation:

We have two types of textbooks. Let's use "x" to represent the number of math textbooks and "y" to represent the number of history textbooks.

Altogether, the bookseller sold 240 math and history textbooks. So:

x + y = 240

Now, the number of history textbooks sold was 72 less than the number of math books sold. So:

y = x - 72

Now we can substitute for y in the equation and solve:

x + y = 240

x + (x - 72) = 240

2x - 72 = 240

2x = 312

x = 156

The bookseller sold 156 math textbooks.

Since y = x - 72, he must have sold 84 history textbooks.

Let's check our answers:

x + y = 240

156 + 84 = 240

That is true, so we did get the correct answers.
