Answer:

There is an error in the application of the DMAS rule, The answer as per the DMAS rule is 75.

Step-by-step explanation:

There is an error in the implication of the DMAS rule of Mathematics.

DMAS rule determines the arrangement of mathematical functions to be performed in an expression where multiple functions are present.

The DMAS Rules describes the following arrangement of the mathematical functions.

1st Division

2nd Multiplication

3rd Addition

4th Subtraction

Applying the above rule the solution is as follow

62 + 3 + 5 x 2

First, we need to solve the Multiplication because there is no division

62 + 3 + 10

Now perform the addition function

65 + 10

Given the graph of a line y=−x. Write an equation of a line (there are many) which intersects the line, but is not perpendicular

BaLLatris [955]

This would be any equation whose slope isn’t -1 or 1.

If the slope was -1, the lines would be parallel because the have the same slope.

If the slope was 1, the lines would be perpendicular because 1 is the negative reciprocal of -1.

Any line with any other slope will intersect with y=-x.

Hope this helps!

Find the MAD for this set of data.

Nostrana [21]

Answer:

Hence MAD=0.8

Step-by-step explanation:

MAD is also known as Mean Absolute Deviation.

We find MAD by the following steps:

Firstly we find the mean of the data
Then we subtract each entry from the mean to obtain the deviation
Then find the absolute value of the deviation which is also known as absolute deviation.
Finally we find the mean of the absolute deviation.

Now we are given a table of the absolute deviation we just need to calculate the mean of the absolute deviation.

The absolute deviation is given as:

1 3 1 0 0 1 0 0 1 1

The mean of this is calculated as:

$\dfrac{1+3+1+0+0+1+0+0+1+1}{10}=\dfrac{8}{10}=0.8$

Hence, MAD=0.8

Which factored form is equivalent to the expression x^2 + 5x + 4? A) (x + 2)(x + 3) B) (x + 4)(x + 1) C) (x + 5)(x − 1) D) (x −

777dan777 [17]

<h3>Answer ↓</h3>

option B.

Calculations ↓

First, let's think of two numbers so that :

if we multiply these numbers, we'll get 4
if we add these numbers, we'll get 5

These numbers are :

4 and 1

Plug these numbers here :

(x+4) (x+1)

So the correct factored form of this expression is

Option B) (x+4)(x+1)
