BRO I TRIED OVER AND OVER AGAIN AND I NEED HELP
torisob [31]

Answer:

Try 116?

Explanation:

First, let's us know the formula for finding area of a rectangle.

Formula - A = l * w

In the image, it shows the length (12) and width (10)

Length = L

Width = W

Now, what is 12 x 10? 120

Because we need the shaded region and the little box isn't apart of it, we need to find the area of that box to and subtract it from big box

The length is 2 and the width is 2, shown by the image.

2x2 = 4

120-4 = 116

If u = (1,3) and v=(2,6) find u + v
Alchen [17]

Answer:

Third option <3, 9>

Step-by-step explanation:

u and v are two vectors and we know the Cartesian components of these vectors.

We must find the sum of u + v.

If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.

u = \\v =

u + v = (1 + 2) i + (3 + 6) j

Where i is the vertical component and j is the horizontal component

Then u + v is

u + v = (3) i + (9) j

u+v =

A student hypothesized that in the US adult population, women drank the same amount of water per day as men per kg of body weigh
Kamila [148]

The conclusion that is justified based on the research is that he rejected the null hypothesis that women drank the same amount of water per kg of body weight per day as men.

<h3>How to illustrate the research?</h3>

It should be noted that a research is simply used to get information about a topic.

In this case, it can be deduced that a type 1 error is committed. This implies the rejection of the null hypothesis when it's true.
