Answer:1/5 is the answer
Step-by-step explanation:
The value of x is for the given trigonometric function is found as: x = 0.1303 + 1/15 *2nπ.
The given expression is:
16 cos(15x) + 8 = 2
On simplification:
cos(15x) = (2-8)/16
cos(15x) = -3/8
15x = arcos ( -3/8 )
15x = 2π - arcos ( -3/8 )
15x = arcos ( -3/8 ) + 2nπ ;or
15x = 2π - arcos ( -3/8 ) + 2nπ ; n ∈ Z
So,
15x = 1.955 + 2nπ
x = 1/15(1.955 + 2nπ)
x = 0.1303 + 1/15 *2nπ , n ∈ Z
Thus, the value of x is found as: x = 0.1303 + 1/15 *2nπ.

The complete question is attached:
2/10 is less, because with a common denominator they are 8/40 and 25/40. Since 5/8 = 25/40, and 8/40 is smaller than that, 2/10 is smaller.
Answer:
2/10 is less than 5/8
Step-by-step explanation:
2/10 =0.20
5/8= 0.625
0.20<0.625
Answer:
[-11,8]

no need explanation, so clear
Answer:
25%
Step-by-step explanation:
So there are four marbles that are red.
It doesnt matter if we have a probability of picking blue because the question says you are picking red.
There are four possible outcomes and one favorable outcome so it is 1/4 of 25/100 or 25%
