Find the distance between each pair coordinates. Select the correct answer. (-8, -8), (4, 8)

hodyreva [135]

ANSWER

20 units.

EXPLANATION

We want to find the distance between (-8,-8) and (4,8).

We use the distance formula:

$d = \sqrt{ {(x_2-x_1)}^{2} + {(y_2-y_1)}^{2} }$

We substitute the points into the formula to get:

$d = \sqrt{ {(4 - - 8)}^{2} + {(8 - - 8)}^{2} }$

We simplify to get;

$d = \sqrt{ {(12)}^{2} + {(16)}^{2} }$

$d = \sqrt{144+ 256}$

$d = \sqrt{400}$

$d = 20$

The distance between the two points is 20 units.

6 7 9

under the sea can be sold for $6 $7 or $9

6, 7, 9

driving test can be sold for $6 $7 or $9

6, 7, 9

here are all the combinations:

p,6

p,7

p,9

s,6

s,7

s,9

d,6

d,7

d,9

since out of 9 combinations driving test is the only one that is not water related lets look at that. There are only 2 combinations of driving test which are less than or equal to $7, (d,7 and d,6) hence the probability of selling no water games for less than $7 is 2/9
