Which statement could be used to describe the functions?

The function f(x)=-3 cos(2x+pi/4) has ___

morpeh [17]

The domain will be ( 0, ∞) and the range of the function F(x) = -3Cos[2x+ $\dfrac{\pi}{4}$ ] will be [ $\dfrac{-\pi}{8}$ , -3 ] and [ $\dfrac{3\pi}{8}$ ,3].

<h3>What are domain and range?</h3>

Range and Domain. The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

The range of the function we can see from the graph of the function will be from [ $\dfrac{-\pi}{8}$ , -3 ] and [ $\dfrac{3\pi}{8}$ ,3]

The domain of the function will be all the values of the real numbers for the function ranges from ( 0, ∞ ).

Therefore the domain will be ( 0, ∞) and the range of the function F(x) = -3Cos[2x+ $\dfrac{\pi}{4}$ ] will be [ $\dfrac{-\pi}{8}$ , -3 ] and [ $\dfrac{3\pi}{8}$ ,3].

The complete question is given below:-

what is the domain and range of the function

F(x) = -3Cos[2x+ $\dfrac{\pi}{4}$ ] .

Ryan, a baker, measured the weights of cakes baked in each batch at his bakery and found that the mean weight of each cake is 50

denpristay [2]

Answer: Rejecting the mean weight of each cake as 500 gram when H subscript 0 equals 500

Step-by-step explanation:

Given that :

Null hypothesis : H0 =500

Alternative hypothesis : Ha < 500

Type 1 Error: Type 1 error simply occurs when we reject the Null hypothesis when the Null is true. Alternatively, type 11 error occurs when we fail to reject a false null hypothesis.

Hence, in the scenario above, a type 1 error will occur when we reject the mean weight as 500 even though the Null hypothesis is True.

Jeanine Baker makes floral arrangements. She has 15 different cut flowers and plans to use 5 of them. How many different selecti

AlladinOne [14]

For the first flower she has a choice of 15. For the second 14 (15 minus the one that was already used). For the third 13, and so on.

Each of the first 15 can be match with any of the second 14. Any of the first pairs can be matched with ant of the third 13 and so on.

This gives us

Number of Selections = Choices for Flower 1 x Choices for Flower 2 x Choices for Flower 3 x Choices for Flower 4 x Choices for Flower 5

$N_{s}=f_{1} \times f_{2} \times f_{3} \times f_{4} \times f_{5}$

$N_{s}=15 \times 14 \times 13 \times 12 \times 11$

$N_{s}=360,360$

You could also calculate this as the permutation $_{15}P_{5}=\frac{15!}{(15-5)!}$
