Answer:
fourth option
Step-by-step explanation:
Using the trigonometric identity
cos²x + sin²x = 1
Divide all terms by cos²x
+
=
which gives
1 + tan²x = sec²x
1. Which choice describes the translation represented by the translation rule (Y) → (*+4,7-17/
1 answer:
Answer:
4 unit to the left side and 1 unit to the down.
Step-by-step explanation:
We have to find the translation which is represented by translation rule
We can see that
The coordinate x shift 4 unit toward left side on x- axis .
The coordinate y shift 1 unit downward on y- axis.
Suppose,we have (x,y)=(4,6)
x=4,y=6
x+4=4+4=8
y=6-1=5
Then, the new coordinate (x',y')=(8,5) is obtained by shifting x- coordinate 4 units towards left and y-coordinate shift 1 unit downward.
Hence, the translation represented by the given translation rule is given by
4 unit to the left side and 1 unit to the down.

Answer:
Mean = 3.12, Variance = 3.324, Standard deviation = 1.8232
Step-by-step explanation:
Total number of students = 10 students.
Given data, 1.1, 5.2, 3.6, 5.0, 4.8, 1.8, 2.2, 5.2, 1.5, 0.8
To find the mean, at first we have to take the sum of all given data and then divide with the number of students.
Let the data is X, = 1.1, + 5.2, + 3.6, + 5.0, + 4.8, + 1.8, + 2.2, + 5.2, + 1.5, + 0.8 = 31.2
Mean = 31.2 / 10 = 3.12
