36.4/(312312*1.065)
36.4/332612.28=0.00 (2dp)
If you meant 312
36.4/(312*1.065)
36.4/332.28=0.10 (2dp)
Hope this helps :)
(I'll assume that the blank spaces are PLUS signs ( + ),
as they usually are on Brainly.)
The mystery complex number is (5 - i) .
(3 + 2i) x (5 - i) = (17 + 7i)
FOIL it out and you'll see it.
Answer:
Step-by-step explanation:
Given that a business school reports that 37% of its graduate students have an engineering background, and 24% have a social science background
In addition, the university’s annual report indicates that the students in its business school comprise 18% of the total graduate population at the entire university.
a) What is the probability that a randomly chosen university graduate student student is a business school student with a social science background?
Prob for business school student and social science background
= ![0.18*0.24\\=0.0432](https://tex.z-dn.net/?f=0.18%2A0.24%5C%5C%3D0.0432)
(b) What is the probability that a randomly chosen university graduate student is neither a business school student with an engineering background nor a business school student with a social science background?
Prob neither business schools student with an engineering background nor a business school student with a social science background
=![1-0.18(0.24+0.37)\\=1-0.1098\\=0.9902](https://tex.z-dn.net/?f=1-0.18%280.24%2B0.37%29%5C%5C%3D1-0.1098%5C%5C%3D0.9902)
Answer:
Step-by-step explanation:
Five equivalent ratios:
7:8 = 14:16
= 21:24
= 70:80
= 49:56
= 35:40
There are several ways you can answer this. The law of cosines may be helpful. It tells you
... c² = a² + b² - 2ab·cos(C)
or
... cos(C) = (a² + b² - c²)/(2ab)
If this value is negative, then angle C is obtuse. Since 2ab is always positive, it amounts to finding the sign of
... a² + b² - c²
Of course, for repetitive calculations, a spreasheet or other machine evaluator is helpful.
The results shown in the figure indicate that side lengths {5, 7, 8} result in an acute triangle.
