Answer:
-38.85 or -24
Step-by-step explanation:
What I do is start with the brackets along with the rest of the numbers involved
2(10) is basically 2 x 10= 20
-39 + 3/20
3/20 = 0.15
-39 + 0.15 = -38.85
Unless if 3/2(10) has 3/2 as a fraction, the answer would be -24
5. We add all the freshman, 92 + 86 = 178.
6. We add all the sophomores surveyed, 116 + 52 = 168,
7. We add the numbers under the "yes" category, 92 + 116, which is 208.
8. We add the numbers under the "no" category, 86 + 52, which is 138.
11. A marginal frequency is the total of freshman, 222, and the total sophomores are 192. The marginal frequency of freshman are greater than that of the sophomores.
(there is no #9, #10, or a table for #12)
