Given a matrix \left[\begin{array}{ccc}a&b&\\c&d&\\\end{array}\right]

Then the determinant = ad - bc

For the matrix \left[\begin{array}{ccc}2&3&\\1&4&\\\end{array}\right]

determinant = (2 × 4) - (3 × 1) = 8 - 3 = 5

Which equation represents the line of BEST fit for the data?
Sladkaya [172]

Equation that fits best in data is y = -30x + 4 .Although there are no options , kindly match this equation to options available!

<u>Step-by-step explanation:</u>

We are given a graph with y & x-axis , with 4 points given and best fit for data can be found out by joining points  . On joining points , we see that best fit is a line . General equation of a line is : y = mx + c ,

where m = slope of line & c = intercept.

Let's calculate slope m :

Consider any two given points , let's have ( 4,0) & (3,30) :

Slope = m

⇒ m = \frac{y_2-y_1}{x_2-x_1}

⇒ m = \frac{0-30}{4-3}

⇒ m = -30

So , equation now becomes : y = mx + c

⇒ y = -30x + c

at x = 0 we have y = 4

y = -30x + c

4 = -30(0) + c

c = 4

Therefore, equation that fits best in data is y = -30x + 4 .Although there are no options , kindly match this equation to options available!

A number is greater than 50 and less than 85 the number has 13 and 3 as factors
alina1380 [7]

Answer:

The Answer is: 78.

Step-by-step explanation:

This one makes you think!

Let n = the number.

The number is greater than 50 and less than 85:

50 < n < 85

Some of the factors are 13 and 3.

So, multiply 13 * 3 = 39.

Multiply again by 2:

39 * 2 = 78.

78 can be factored as:

13 * 3 * 2 = 78, and it is greater than 50 and less than 85.

The number is 78.

Hope this helps! Have an Awesome Day!! :-)
