Pluto has been hard to measure from earth because of its atmosphere. in 2007 young, young, and buie measured pluto as having a diameter of 2322 km. in 2015 the new horizons probe reached pluto and measured it up close and we now know the actual diameter is 2372 km. what was the percent error of the 2007 measurement?

2.15% was the percent error of the 2007 measurement.

Step-by-step explanation:

To calculate the percentage error, we use the equation:

We are given:

Experimental value of diameter of Pluto ,2015= 2372 km

Theoretical value of diameter of Pluto, 2007 = 2322 km

Putting values in above equation, we get:

Hence, 2.15% was the percent error of the 2007 measurement.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
