May someone help me with this plzzz

Anna71 [15]

Her book was 10 days late. D = days. The equation is .25(4) + .30d = 4.00. First you multiply .25 • 4 to get 1. Then you subtract 1 from both sides and get .30d = 3. Next you divide both sides by .30 to get d = 10.

What I the slope of a line that is perpendicular to the line 2y-3x=8

Zolol [24]

<u>ANSWER</u>

$- \frac{2}{3}$

<u>EXPLANATION</u>

The given given equation is

$2y - 3x = 8$

We need to rewrite this equation in the slope-intercept form:

$y = mx + b$

We add 3x to both sides.

$2y - 3x + 3x=8 + 3x$

$\implies \: 2y = 3x + 8$

We divide through by 2 to get,

$y = \frac{3}{2}x + 4$

The slope of this line is

$m = \frac{3}{2}$

Let the slope of the line perpendicular to this line be 'n' .

Then the product of the slopes of two perpendicular lines is always negative 1.

$m \times n = - 1$

$\implies \: \frac{3}{2} n = - 1$

$\implies \: \frac{2}{3} \times \frac{3}{2}n = - 1 \times \frac{2}{3}$

$n = - \frac{2}{3}$

Therefore the slope of the new line is

$- \frac{2}{3}$

Associate the average of the numbers from 1 to n (where n is a positive integer value) with the variable avg.

Kaylis [27]

This is a simple programming question. To calculate the average of any two numbers, where one number is 1 and the other is n, simply add the two numbers and divide by 2. Therefore, the answer is:
<span>avg = (1 + n) / 2</span>

Determine if the following event is independent or dependent. Ursula went to the market and chose a blue marker from one box of

erastova [34]

Because is likely that the first outcome affected the second one, we can conclude that the events are dependent.

<h3>When two events are independent?</h3>

Two events are independent if the outcome of one can't affect the outcome of the other.

Here, first, she chooses a blue marker from one box and then a yellow one from another, these are the two events.

Now, these are independent or dependent?.

Well, the fact that she chooses a blue marker first, means that she probably would not want to choose another blue marker for the second one. So yes, the first outcome does affect the second outcome, meaning that the events are dependent.
