The grid shows the positions, in miles, of a subway stop and a house. The image is of a 2-dimensional graph with an x-axis and a

Arte-miy333 [17]

Here we can use the distance formula. We label one point $( x_{1}, y_{1})$ and the other $( x_{2}, y_{2})$ . It doesn’t matter which point we label with the 1s and which we label with the 2s. The distance will be the same either way (the distance from the subway to the house is the same as that from the house to the subway — to give a related easier to follow example). What does matter is that the 1s are together and the 2s are together.

So let’s call (-4,-3) $( x_{1}, y^{1})$ which means that -4 is $x_{1}$ and -3 is $y_{1}$ . We call the other point (4,3) $( x_{2},y_{2})$

The distance formula is $d= \sqrt{( x_{2} - x_{1} )^{2} +( y_{2}-y_{1})^2 }$

We substitute using the points given and obtain:
$d= \sqrt{(3- - 3) ^{2} +( 4- -4)^2 }$

and simplify to get $\sqrt{16+9}= \sqrt{25}=5$

The distance is 5 miles

In the diagram, CE = 12 and BE = 5. Based on the given information, AE =

lubasha [3.4K]

Answer:

12 units

Step-by-step explanation:

From the given figure, it can be seen that AB=BC, thus

From ΔBEC, using the Pythagoras theorem, we have

$(EC)^{2}=(BE)^{2}+(BC)^{2}$

$(12)^2=(5)^2+(BC)^2$

$144=25+(BC)^2$

$119=(BC)^2$

$BC=\sqrt{119} units$

Now, from ΔABE, using the Pythagoras theorem, we have

$(AE)^2=(BE)^2+(AB)^2$

$(AE)^2=25+119$

$(AE)^2=144$

$AE=12 units$

Thus, the measure of AE is 12 units.

A graduate student designs a research study. She hopes to show that the results of her experiment are statistically significant.

Mekhanik [1.2K]

Answer:

A small P-value.

Step-by-step explanation:

A small P- value.

A small P- value , P-value indicates that the results are statistically significant.

P value in Statistics helps to perform hypothesis test and it helps to determine the significance of the results.

A small P- value typically (P<0.05) indicates strong evidence against the null hypothesis so, we reject the null hypothesis, on contrary when P- value is large we cannot reject the null hypothesis.
