234 chocolates are to be packed into boxes Each of which will contain 11 chocolates. How many boxes of chocolates will there be?

vazorg [7]

Hello!

Divide the total amount of chocolates by the number of chcolates each box will contain.

234 ÷ 11 = 21.2727272727

It is a repeating decimal. Now, obviously there won't be 21.2727272727 boxes chcolates.

11 × 21 = 231

11 × 22 = 242

If you multiply 11 by 21, you get 231 -- which is 3 less than the total amount of chocolates. But if you multiply it by 22, you get a number that is greater than 234, so it is not possible.

ANSWER:

There will be 21 boxes of chocolates, and 3 left over.

Select the correct answer. to solve this system of equations using substitution, what could be substituted in place of y in the

Rina8888 [55]

To use substitution to evaluate this system of equations, the y value to be substituted is 2x - 7.

<h3>What is method of substitution?</h3>

The algebraic method for solving simultaneous linear equations is the substitution method. The values of one variables from one expression is substituted with in second equation, as the name implies.

Now according to the question;

The expressions are as follows;

4x = 5 – 2y and y – 2x + 7 = 0

To solve the following system of equations, we must determine what substitution must be made in place of y in the first equation.

Let us now deduce the value of y from the second equation.

y – 2x + 7 = 0 ⇒ y = 2x – 7

We now have the y value, which we can plug into the first equation;

⇒ 4x = 5 – 2(2x – 7)

4x = 5 – 4x + 14

4x + 4x = 5 + 14

8x = 19

x = 19/8

Substitute the value of x in y to get its value.

y = 2×(19/8) - 7

y = -9/4

Thus, the values obtained for the given set of equations are-

x = 19/8 and y = -9/4 by method of substitution.

What is the standard deviation of the population: Use the stdevp function in the Desmos graphing calculator.

Mice21 [21]

The standard deviation of the given data is 3.5

<h3 /><h3>How to calculate the standard deviation of data?</h3>

Standard deviation is used to determine the rate of dispersion of data with respect to the mean.

The formula for calculating the standard deviation of data is given as:

$\sigma = \sqrt{\frac{\sum (x-\overline x)^2}{n-1} }$

Given the data below:

10.4, 10.3, 11.7, 11.1, 8, 4.4, 2.6, 1.8, 2.5, 4.4, 7.3, 9.5

Using the stdevp calculator the standard deviation is calculated as:

σ = √12.405

σ = 3.5

Hence the standard deviation of the given data is 3.5
