This question is incomplete. There are options in the question (from reference) and no highlight in the red bolded text in the question.

What effect does decreasing the temperature of a room have on a lifespan of a battery?

Which variable is highlighted in red, bolded tex?  

a . Independent

b . Dependent

c . Control

d . None

But the answer to both the independent and dependent variables will be provided and explained in detail.

Answer:

Independent variable: decrease in temperature

Dependent variable: lifespan of battery

 Step-by-step explanation:

The independent variable in an experiment is defined as the variable that can be changed or manipulated in order to find an outcome while the dependent variable is defined as the variable that is influenced by the changes in the independent variable.

In the given example, a decrease in temperature  is the dependent variable as it is changing and the lifespan of battery  is the dependent variable as it is responding to the independent variable ?9decrease in temperature).

Please help me I will mark brainliest! The ratio of the number of boys to the number of girls in a school is 3:4. One-third of t
Alex17521 [72]

Answer:

a) 952

b) 136

Step-by-step explanation:

<u>Ratio of b:g = 3:4, based on this we have:</u>

  • Number of boys = 3x
  • Number of girls = 4x
  • Total number of pupils = 3x+4x = 7x

<u>Number of spectacle wearers:</u>

  • 1/3*3x + 3/8*4x = x + 3/2x = 2.5x

<u>Number of those not wearing spectacles:</u>

  • 7x - 2.5x= 4.5x

<u>And this number equals to 612, then we can find the value of x:</u>

  • 4.5 x = 612
  • x= 612/4.5
  • x= 136

a) T<u>otal number of pupils:</u>

  • 7x = 7*136 = 952

b)<u> The difference in the number of boys and girls:</u>

  • 4x-3x= x = 136

Pls help need this ASAP !
elena-s [515]
A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).

In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.

The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”

Please help very confused! How do you graph the solution set to a system of linear inequalities in two variables?
BlackZzzverrR [31]
<h3>Step-by-step explanation:</h3>

We will use as an example the following system of inequalities:

  • 3x +2y ≥ 5x -4
  • y < (1/2)x +3

For each inequality, do the following:

1. If it is not this way already, arrange the inequality so that each variable appears on only one side of the inequality. Putting the inequality into any of the standard forms will do this. It will be helpful later if you arrange the inequality so that at least one variable has a positive coefficient. (You may have to multiply by -1 (and change the sense of the inequality) to do this.)

Our example inequalities are now ...

  • -2x +2y ≥ -4 . . . . . or divide by 2 to get . . . . -x +y ≥ -2
  • y < (1/2)x +3

2. Notice the inequality symbol, and whether it includes the "or equal to" case.

  • the first inequality is ≥, so includes "or equal to"
  • the second inequality is <, so <em>does not</em> include "or equal to"

3. Replace the inequality symbol with an equal sign and graph the resulting equation. If the "or equal to" case is included, the line is graphed as a solid line. If it is not, then the line is graphed as a dashed line.

  • the first equation (-x +y = -2) is graphed with a solid line
  • the second equation (y = (1/2)x +3) is graphed with a dashed line

4. It is not necessary, but is less confusing, to choose a variable in the inequality (after step 1) that has a <em>positive</em> coefficient. Notice whether this variable is "less than" or "greater than" the stuff on the other side of the inequality.

  • y ≥ . . . . for the first inequality
  • y < . . . or . . . x > . . . . for the second inequality

If it is less than, shade the portion of the graph below (for y <) or to the left (for x <) of the line you graphed in step 3.

  • the second inequality has y < , so the graph will be shaded <em>below</em> the dashed line. It also has x > , so will be shaded <em>to the right</em> of the dashed line. (These are the same shading.)

If it is greater than, shade the portion of the graph above (for y >) or to the right (for x >) of the line you graphed in step 3.

  • the first inequality has y ≥ , so the graph will be shaded <em>above</em> the solid line.

5. The solution set is where the shaded areas overlap. Any point on a dashed line is not in the solution set.

_____

The graph for the example inequalities is attached. The first one is graphed and shaded in red; the second one is graphed and shaded in blue.
