<h3>hello!</h3>

==========================================================

Let's simplify the expression:-

$\bigstar{\boxed{\frac{3}{1} *\frac{1}{2}}$

Multiply 3 times 1 and 1 times 2:-

$\bigstar{\boxed{\pmb{\frac{3}{2} }}$

======================================================

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)

The equation of line QR is x + 2y = 2. What is the equation of a line perpendicular to line QR in slope-intercept form that cont

Elza [17]

Answer:

y = 2x-4

Step-by-step explanation:

x + 2y = 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

First find the slope of the line

2y = -x+2

Divide by 2

y = -1/2x +1

The slope of this line is -1/2

We want a line that is perpendicular, which is the negative reciprocal

-1 /(-1/2) = 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the line

6 = 2(5)+b

6 = 10+b

6-10 =b

-4=b

y = 2x-4

An example of dependent events is drawing a red marble out of one jar and then drawing a

sladkih [1.3K]

Answer:

Second Option:

"green marble out of the same jar, without replacing the first marble"

Step-by-step explanation:

Two events r and s are independent if the probability that r occurs does not affect the probability that s occurs.

When choosing an object of some color b from a jar with n objects where there are x objects of the desired color b, the probability of obtaining 1 object of color b when randomly selecting an object from the jar is:

$P_1 =\frac{x}{n}$

If after taking the object it does not return it to the jar (without replacement) then, now the probability of obtaining an object of color b is:

$P_2 = \frac{x-1}{n-1}$ if the one selected in the first trial was the color b.

$P_2 = \frac{x}{n-1}$ if the one selected in the first test was not the color b

Note that now the probability P depends on the result obtained in the previous test.

This event is dependent.

However, if by take object b in the first test, and the object is returned to the jar, and then the second test is made, then

$P_1 = P_2$ .

The probability does not depend on the result of the first trial. The same happens if the objects are taken from different jars.

These would be independent events.

Finally the correct option is the second option.

Given the Trapezoid ABCD Find the length of AD Pls hellpppp

matrenka [14]

Given:

In trapezoid $ABCD, AD\parallel BC, MN$ is the mid-segment of $ABCD, AD=30x-10,MN=31x+1,BC=30x+28$ .

To find:

The length of $AD$ .

Solution:

We know that the length of the mid-segment of a trapezoids is half of the sum of lengths of two parallel sides of the trapezoid.

In trapezoid $ABCD$ ,

$MN=\dfrac{AD+BC}{2}$

$31x+1=\dfrac{30x-10+30x+28}{2}$

$31x+1=\dfrac{60x+18}{2}$

$31x+1=30x+9$

Isolate variable terms.

$31x-30x=9-1$

$x=8$

Now,

$AD=30x-10$

$AD=30(8)-10$

$AD=240-10$

$AD=230$

Therefore, the length of $AD$ is 230.
