Answer:

B) 400 pounds

Step-by-step explanation:

w => weight

w + 831 ≤ 1250

x ≤ 1250 - 831

x ≤ 419

the elephant can carry amount of additional weight 419 pound or less than 419 pounds.

Hope this helps ^-^

Use a graphing calculator to determine the linear, quadratic, or exponential equation that best represents the data. For linear

Sav [38]

The linear equation that best represents the data is given by:

y = 1.35x - 2.11.

<h3>Why is the data best represented by a linear equation?</h3>

We have to consider two things:

The data increases over the entire interval, not having changes in the behavior related to increasing/decreasing, hence a quadratic equation would not be a good representation for the data.

The increase is best followed by a constant, especially for higher values, and not by a multiplier, hence a linear function is selected over an exponential function.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points are given as follows:

(1, 0.2), (2, 0.4), (3, 1.1), (4, 2.3), (5, 5.1), (6, 6.3), (7, 7.5).

Inserting these points into the calculator, the equation is given by:

y = 1.35x - 2.11.

A book has a front and a back and 400 pages. The front and back cover are each 0.9mm thick measured to 1 decimal place. Each pag

zhuklara [117]

The minimum thickness of the book would simply be the sum of the thickness of the two cover pages and all the pages in between. That is:

minimum thickness = 0.9 mm * 2 + 0.13 mm * 400

<span>minimum thickness = 53.8 mm</span>

#19 is the question. i’m stuck on it, i missed the class where we went over it. please help!!

vodka [1.7K]

Step-by-step explanation:

Since the powers are equal you can write the expression as a one root

But we cannot get 9 out since the square root of 9 is 3 which is second power (3^2) and the power of the root is 4

Holpe this helps, if you need further explanation you can ask.

The algebra tiles represent the perfect square trinomial x2 10x c. what is the value of c? c =

devlian [24]

The value of c for which the considered trinomial becomes perfect square trinomial is: 20 or -20

<h3>What are perfect squares trinomials?</h3>

They are those expressions which are found by squaring binomial expressions.

Since the given trinomials are with degree 2, thus, if they are perfect square, the binomial which was used to make them must be linear.

Let the binomial term was ax + b(a linear expression is always writable in this form where a and b are constants and m is a variable), then we will obtain:

$(ax + b)^2 = a^2x^2 + b^2 + 2abx$

Comparing this expression with the expression we're provided with:

$x^2 + 10x + c$

we see that:

$a^2 = 1 \implies a = \pm 1\\b^2 = 10\\b = \pm 10\\2ab = c\\\pm2(10)1 = c\\c = \pm 20\\$

Thus, the value of c for which the considered trinomial becomes perfect square trinomial is: 20 or -20

The owner of a skate shop notices that every time a certain employee has a shift, there are higher sales numbers at the end of t

Serjik [45]

Answer:

Correlation.

Step-by-step explanation:

When relationship between two or more variables are to be established such that the measure of the effect of one variable (independent variable) on the other variable (dependent variable) is evaluated , this is called correlation study or analysis. In the scenario above, the relationship between productivity or revenue and employee shift is correlated, that is a relationship was established between the revenue made and the shift days of a particular employee, which yielded a positive association between the two variables. The employee shift is the independent variable and the revenue made is the dependent variable.
