ACTIVITY 1. Given the following cases, solve for mean, standard deviation and variance. Express the measurement of the physical quantity completely.
1. In an experiment, 5 trials were done to determine the inside diameter of a ring. The measurements are as
follows: 1.24cm, 1.31cm, 1.28cm, 1.29cm,1.19cm mean, x= standard deviation, or
variance, oʻ=
Diameter of the ring =
2. During an experiment, a group of students was asked to measure the height of a liquid in a graduated
cylinder. The measurements were as follows: 5.3ml, 5.4ml, 5.6ml, 5.8ml, 5.1ml and 4.9ml.
mean, x= standard deviation, a = variance, height of the liquid

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.
