2.145 is divisible by which numbers 2 6 5 3​

Mathematics
1 answer:
mariarad [96]2 years ago
6 0

Answer:

  • 3 and 5 if "." marks thousands
  • 2, 3, 5, 6 if "." is a decimal point

Step-by-step explanation:

The number 2145 is not even, so will not be divisible by 2 or 6. It ends in 5 so is divisible by 5. Its sum of digits is 12, which is divisible by 3, so the number is divisible by 3.

2145 is divisible by 3 and 5.

2.145 is divisible by all of these numbers:

  2.145/2 = 1.0725

  2.145/6 = 0.3575

  2.145/5 = 0.429

  2.145/3 = 0.715

_____

Here, we take the mixed number to be divisible if the decimal representation of the quotient is a terminating decimal fraction.

4 green marbles, 5 red marbles, and 2 yellow marbles are placed into a bag. One marble is chosen and replaced into the bag. A se
Ipatiy [6.2K]

Answer:

The probability is 10/121

Step-by-step explanation:

In this question, we are tasked with calculating probability.

The probability to be calculated is that we have an ordered selection of picking a red marble after which we pick a yellow marble.

Firstly let us know the total number of marbles we have. That will be 4 + 5 + 2 = 11 marbles

Probability of picking a red marble will be 5/11 while the probability of picking a yellow marble will be 2/11

Now, the probability of picking a red marble before a yellow marble will be mathematically equal to; P(r) * P(y) = 5/11 * 2/11 = 10/121

Please help??! Solve by elemination <br>4x + y = 6<br>12x + 3y = 18<br>Show your work
RUDIKE [14]
Multiply -3[4x+y=6].
This gets you -12x-3y=-18.
Add the two equations together to eliminate the y.
-12x - 3y = -18
+ 12x + 3y = 18
------------------------
0 = 0
This means that these are in fact the same line, therefore there are infinite solutions.

A student is assessing the correlation between the number of workers in a factory and the number of units produced daily. The ta
lukranit [14]

The number of units produced increases from 2 to 452 as the number of factory workers increases from 0 to 90, which gives;

Part A:

  • Yes there is a strong positive correlation

Part B:

  • The function is <em>y</em> = 5•x + 2

Part C:

  • The slope indicates the number of units produced by each worker daily

  • The y-intercept indicates that two units can be produced without workers.

<h3>How can the existence of a correlation and the best fit function for the data be found?</h3>

Part A:

The correlation is the relationship between variables based on statistical data.

From the given table, the difference between consecutive terms of the <em>x </em>and y-values are constant, therefore as the x-values increases, the corresponding y-value increases.

Change in x-values, ∆x = 10 - 0 = 20 - 10 = 30 - 20 = 10

Change in y-values, ∆y = 52 - 2 = 102 - 52 = 152 - 102 = 50

Therefore;

  • There is a strong positive correlation between the number of workers, <em>x</em>, and the number of units produced, <em>y</em>.

Part B:

Given that the rate of change of the x-values is constant, and the rate of change of the y-values is a constant, the function relating the <em>x </em>and y-values is a linear function, which can be found as follows;

Slope of the equation, <em>m </em>= ∆y/∆x

Which gives;

m = 50/10 = 5

y - 2 = 5•(x - 0)

The function that best fits the data is therefore;

  • y = 5•x + 2

Part C:

The slope of the function is the coefficient of the variable <em>x </em>in the equation, <em>y </em>= m•x + c

  • The slope of the plot, 5, indicates that each worker produces 5 units daily

The y-intercept of the function is the value of the constant term, c, in the equation, y = m•x + c

  • The y-intercept of the linear equation, y = 5•x + 2, which is 2, indicates that the initial number of units of products at the factory before workers arrive is 2.
