Do you always copy change change while subtracting negative integers?

Evgesh-ka [11]

Think of it like this: imagine a frog on some lily pads and if it hops left it gets smaller(negative) and if it hops right it gets bigger(positive) ,(but think of it like numbers) so -14-5 think about the -14 being way down at the left and then you add on the (-5) since the number you are adding is negative it is getting smaller (going farther away from the zero, not closer) so when you add a negative to a negative number you get smaller instead of bigger. Hope that helps

The director of the library believes that 14% of the library's collection is checked out. If the director is right, what is the

Ksivusya [100]

Answer: 0.2643

Step-by-step explanation:

Let p be the population proportion and $\hat{p}$ be the sample proportion .

As per given question , we have

$p=0.14\\\\ \hat{p}=0.13\\\\ n=478$

z-score : $\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

$z=\dfrac{0.13-0.14}{\sqrt{\dfrac{0.14(1-0.14)}{478}}}\\\\=-0.630087269176\approx-0.63$

The required probability ( using z-table ):-

$P(z$

Hence, the probability that the proportion of books checked out in a sample of 478 books would be less than 13% = 0.2643

Find the quotient. -300x5y4 ÷ xy2 -150 x6y6 -300 x6y6 300 x4y2 -300 x4y2

exis [7]

Answer:

d. -300 x4y2

Step-by-step explanation:

Here is the correct question: Find the quotient. -300x5y4 ÷ xy2

a. -150 x6y6

b. -300 x6y6

c. 300 x4y2

d. -300 x4y2.

Given: -300x5y4 ÷ xy2

Now, simplifying it

Using law of indices to solve it.

= $-300x^{5} y^{4} \div xy^{2}$

we know, $\frac{x^{m} }{x^{n} } = x^{m-n}$

= $-300x^{5-1} y^{4-2}$

= $-300x^{4} y^{2}$

Hence, the answer is $-300x^{4} y^{2}$

What is the formula to find domain?

fomenos

The domain of a function is the set of all possible inputs for the function.

What are the domain and range?

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Let y = f(x) be a function with an independent variable x and a dependent variable y.

If a function f provides a way to successfully produce a single value y using for that purpose a value for x then that chosen x-value is said to belong to the domain of the function.

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x).

Hence, the domain of a function is the set of all possible inputs for the function.
