Question

10 unit1 exploring one - variable data

1. cubesat missions a cubesat is a miniature satellite used for space research that can be easily deployed from a launch vehicle or from the international space station. more than 1000 cubesats have been launched since specifications for these satellites were jointly developed by cal poly san luis obispo and stanford university in 1999. the relative frequency table summarizes data on the type of mission for each cubesat launched in november and december 2019.

mission type	proportion
technology	0.28
imaging	0.34
communications	0.12
education	0.08

(a) there were a total of 50 cubesats launched during these two months. how many had a communications mission type?

Explanation:

Step1: Identify the formula

To find the number of Cube - Sats with a communications mission type, we use the formula: Number = Total number×Relative frequency.

Step2: Substitute the values

The total number of Cube - Sats launched is 50, and the relative frequency of the communications mission type is 0.12. So, the number of Cube - Sats with a communications mission type is \(50\times0.12\).

Step3: Calculate the result

\(50\times0.12 = 6\).

Answer:
