Answer:

1/10

Step-by-step explanation:

There are three simple fractions in this problem:  3/5, -1/4 and 7/10.  Rules of order require that the division (-1/4) divided by 7/10 be carried out first; the correct product is  -10/28, or -5/14.  Then we have 3/5 + (-5/14).

Here the LCD is 70.  Then 3/5 + (-5/14) becomes 42/70 - 35/70, which simplifies to 1/10.

This is the example my teacher used. However, I still don't understand what makes the integers even or odd. I was hoping someone
kow [346]

Answer:

<h2>Here's what makes an integer odd:</h2>
  • It is NOT a multiple of 2.
  • When divided by 2, the quotient would be a decimal or have a remainder or fraction.

<h2>Here's what makes an integer even:</h2>
  • It is a multiple of 2.
  • When divided by 2, the quotient has a whole number.

<em>The odd numbers from one to 10 are: 1, 3, 5, 7, 9.</em>

<em>The even numbers from one to 10 are: 2, 4, 6, 8, 10. </em>

  • With big numbers, if it ends with any of the odd numbers from one to ten, listed above, it would be odd. This goes for the same with even.
<h2>With the x + 2, x + 4, etc:</h2>
  • An odd number and even number has a pattern....

[odd, even, odd, even, odd...] [1, 2, 3, 4, 5]

  • So, if x was an odd number, adding it by 2, 4, 6, etc. will result in another odd number.

Here's an example:

x= 17\\x + 2 = ?\\(17) + 2 = 19

<em>See how x is an odd number and the sum of the number and two makes another odd number? </em>

The same can go with an even number:

x=2\\x + 6 = ?\\(2) + 6= 8

<em>See how x is an even number and the sum of the number and six makes another even number? </em>

I hope my answer helps you understand even and odd numbers.

For simple linear regression, y = β0 + β1x + u, which one of the following statements is true?
RSB [31]

Answer:

Option a) u is called the "error term". It is the error we make in prediction

Option d) x is called the independent variable because x is independent from y and u.

Step-by-step explanation:

We are given the following information in the question:

y = \beta_0 + \beta_1x + u

where y is the dependent variable, x is the independent variable.

\beta_0: It is the value of y when x is zero, that is y-intercept.

\beta_1: It is the coefficient of x in predicting the dependent variable y.

u is the error term.

  • An error term represents the margin of error.
  • It refers to the sum of the deviations within the regression line, that is the difference between the predicted value and the observed value of y.

Thus, Option A) u is the error term and Option D)  x is called the independent variable because x is independent from y and u are the correct answer.
