Hitung jarak di antara titik P(7, 1) dengan titik Q(7, 8)

MaRussiya [10]

Answer:

7 units

Step-by-step explanation:

Distance between 2 points

= $\sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }$

Thus, distance PQ

$=\sqrt{(8 - 1)^{2} + (7 - 7)^{2} } \\ = \sqrt{7^{2} } \\ = 7$

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.

John is about to roll a six-sided, fair number cube 60 times. He wants to predict how many times the cube will land on an even n

Juli2301 [7.4K]

Even numbers
so each dice has numbers
1,2,3,4,5,6
the eve numbers are
2,4,6
odd are others
1,3,5
so 1/2 are odd

therefor 1/2 of 60 is how many times it would get even
1/2 of 60=1/2 times 60=30

No not good predicition
my prediction would be 30 tiemes
