Answer:
0.24
Step-by-step explanation:
it was 0.24161073 not simplified but since the 1 after the 4 is not greater than five it stays the same and it beccome 0.24
Answer:
The values of x that satisfy the given equation are:
x1 = 1.183 + nπ
x2 = -1.183 + nπ
Step-by-step explanation:
Given tan²x - sin²x/sin²x = 5
Simplifying this, we have
tan²x - 1 = 5
Adding 1 to both sides, we have
tan²x = 6
Because tan²x = (tanx)², we can write as
(tanx)² = 6
Taking square roots of both sides, we have.
tanx = ±√6
x = arctan(±√6) + nπ
≈ 1.183 + nπ or -1.183 + nπ
Answer: 0.68
Step-by-step explanation:
given data:
ABC market share = 30%
number of customers surveyed = 800
probability that more than 32% prefers ABC
Solution:
32% of 800
= 256 persons
p ( x ≥ 256 )
= 1 - ( 256/800 )
= 1 - 0.32
= 0.68
the probabiliy that more than 32% of those who carried out the survey would prefer ABC brand is 0.68.
Answer:
x = 33
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180 for x
x = 180 - (90 + 57) = 180 - 147 = 33
