Solution:-
- Claim : pizza shop deliver in 30 minutes or less or it is free.
- Alternate : People who live in on opposite side of town believe it will take the pizza shop longer than 30 minutes to make and deliver the pizza.
- Sample size taken n = 50 > 30
- The sample mean = 32 mins
- The appropriate symbol for sample mean used in test statistics is (u).
Answer:
Subtract 63 from both sides
Step-by-step explanation:
we always have to try to clear the incognita that in this case is going to be h
First we
Subtract 63 from both sides
then
Divide by -7 on both sides
19 - 7h = 63
19 - 7h - 19 = 63 - 19
- 7h = 44
-7h/-7 = 44/-7
h = -44/7
Answer:
Only options A and B are correct, i.e. y = sin∅ and y = cos∅.
Step-by-step explanation:
The graphs that oscillate, should be periodic in nature and continuous functions.
We know all trigonometric functions are periodic in nature. But not all trigonometric functions are continuous.
The function is continuous if its values are defined at all angles and it should not be undefined for any particular angle.
We know the following facts:-
tan(90°) = ∞
sec(90°) = ∞
csc(0°) = ∞
cot(0°) = ∞
<u>Only sin and cos don't have values ∞ at any angle.</u> It means only sin and cos are continuous functions.
Hence, only options A and B are correct, i.e. y = sin∅ and y = cos∅.
