Mike is 5 years old and Randy is 8 years old. Select all proportional relationships that have the same ratio to that of mike and randys age ​

Answer:

[tex]2.5\; \rm m^3[/tex].

Step-by-step explanation:

Let [tex]V_1[/tex] and [tex]P_1[/tex] denote the volume and pressure of this gas before the change. Let [tex]V_2[/tex] and [tex]P_2[/tex]denote the pressure of this gas after the change.

The ratio between the volume of this gas before and after the change would thus be [tex]\displaystyle \frac{V_1}{V_2}[/tex].

The ratio between the pressure of this gas before and after this change would be [tex]\displaystyle \frac{P_1}{P_2}[/tex].

Because the volume of a given mass of (ideal) gas varies inversely with pressure, these two ratios should be reciprocal of each other. That is:

[tex]\displaystyle \frac{V_1}{V_2} = \frac{1}{\displaystyle \displaystyle \left(\frac{P_1}{P_2}\right)}[/tex].

In other words:

[tex]\displaystyle \frac{V_1}{V_2} = \frac{P_2}{P_1}[/tex].

Rearrange and solve for [tex]V_2[/tex], the volume of this gas after the change:

[tex]\displaystyle V_1 = V_2\cdot \left(\frac{P_2}{P_1}\right)[/tex].

[tex]V_2 = \displaystyle V_1 \cdot \left(\frac{P_1}{P_2}\right)[/tex].

From the question:

Solve for [tex]V_2[/tex]:

[tex]\begin{aligned} V_2 &= V_1 \cdot \left(\frac{P_1}{P_2}\right) \\ &= 2\; \rm m^3 \times \frac{500\; \rm N \cdot m^{-2}}{400\; \rm N \cdot m^{-2}} = 2.5\; \rm m^3\end{aligned}[/tex].

Answer:

( 1 ; -2 )

Step-by-step explanation:

x + 3y = -5..............1

5y - 10 = -20x........2

x = -5 - 3y..............3

5y - 10 = -20( -5 - 3y)

5y - 10 = 100 + 60y

-55y = 110

y = -2

x = 1

Answer:

Option B is the correct answer

Answer:

Largest: 800,499

Smallest: 799,500

The required largest number is 8,00, 499 and the smallest number is 7,99, 500.

Given that,
800,000 rounded to the nearest hundred thousand.
To determined the largest and smallest number.

What is rounding of values?

The rounding of values is superseding a number with an inexact value that has a more ephemeral, more uncomplicated, or more direct representation.

Here,
Any number range -500 and + 499 to 8,00,000 will be the smallest and largest number that could be rounded to 8,00,000.

smallest number  = 8,00,000 - 500 = 7, 99, 500

largest number = 8,00,000 + 499 = 8,00,499

Thus, the required largest number is 8,00, 499 and the smallest number is 7,99, 500.

Answer:

Convergent

Step-by-step explanation:

This is an alternating series where bn = 2n / eⁿ.  Apply the alternating series test:

lim(n→∞) bn

= lim(n→∞) (2n / eⁿ)

Use L'hopital's rule:

= lim(n→∞) (2 / eⁿ)

= 0

For n ≥ 1, the series is decreasing. 2(n+1) / eⁿ⁺¹ < 2n / eⁿ.

Therefore, the series converges.

The outlier of the data that represents the miles jogged by Mary each day for the past nine days is 0.

An outlier is a number that is very different from other data in a data set. It is either very big or way smaller than the other numbers.

Answer:

The slope is -1/1 or just -1.

(When you need to plot the slope, you use -1/1 to use the strategy Rise/Run or Rise over Run.

If you look at the point (-3,1) From that point, you go down -1 and you run to the side for a positive 1.

Once you do that you'll land at (-2,0) and you can keep on repeating this and you'll see that it lands on the points on the line.

Given parameters:

Percentage of enrollment of 3-year-olds = 40%

Unknown:

Probability that a randomly selected 3-year-old is enrolled in a day care = ?

Probability is the likelihood of an event to occur.

   Probability  = [tex]\frac{Possible outcome}{Total out come}[/tex]

In this problem, 40% of the total number of 3-year-olds are enrolled in a day care.

  We can say, out of every 100 3-year-olds, 40 of them will enroll in day care.

The possible enrollment is 40 and the total is 100;

Input the parameters and solve;

      Probability  = [tex]\frac{40}{100}[/tex]   = [tex]\frac{2}{5}[/tex]

The probability that any randomly selected 3 year old is enrolled in day care is [tex]\frac{2}{5}[/tex]
