All solutions to the equation 3 cos (5t) + 3 = 2 in the interval from 0 to π will be 0.3821, 0.2462, and 0.8745. Then the correct option is A.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The equation is given below.
3 cos (5t) + 3 = 2
By simplifying the equation, then we have
3 cos 5t = -1
cos 5t = -1/3
Then the value of t will be
5t = 1.91063, 1.12096, 4.3725
t = 0.3821, 0.2462, 0.8745
Then the correct option is A.

Answer:
mean = 254.6
median = 120
mode = 60
midrange = 958
For average data sets i prefer by finding the mean
Step-by-step explanation:
mean :
(98+120+493+206+73+102+183+870+76+60+60+112+147+1018+201) ÷ 15 = 254.6
median : 60 60 73 76 98 102 112 120 147 183 201 206 493 870 1018
find the middle number
= 120
mode :
number that is more than one
= 60
midrange :
highest number - smallest number
= 1018 - 60
= 958
B. The independent quantity is definitely not the words cause' of you think about it the number of words depends on the number of minutes.
