The <em><u>correct answers</u></em> are:
90°, 180° and 270°
Explanation:
Squares have rotational symmetry at 90°. This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:
360/4 = 90
This means that at all multiples of 90, the square will rotate onto itself. This means that 90, 180 and 270 are all correct.
Answer:
We have (60/100)·x - 17 = - 65;
Then (6/10)·x = 17 - 65;
(3/5)·x = - 48;
x = (5/3)·(-48);
x = 5·(-16);
x = - 80;

Answer: 0.0475
Step-by-step explanation:
Given : A firm’s marketing manager believes that total sales X can be modeled using a normal distribution.
Where , Population mean : 
Standard deviation : 
To find : Probability that the firm’s sales will exceed $3 million i.e. $ 3,000,000.
∵ 
Then , for x= 3,000,000
Then , the probability that the firm’s sales will exceed $3 million is given by :-
Hence, the probability that the firm’s sales will exceed $3 million = 0.0475
