What are domain and range?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 [[tex]\dfrac{-\pi}{8}[/tex] , -3 ] and [ [tex]\dfrac{3\pi}{8}[/tex],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+[tex]\dfrac{\pi}{4}[/tex]] will be [[tex]\dfrac{-\pi}{8}[/tex] , -3 ] and [ [tex]\dfrac{3\pi}{8}[/tex],3].

If pound of cheese costs $3.43, what is the cost per pound?
PLS HELP
Answer:
$3.43
Step-by-step explanation:
Cost per pound means how much you are paying for one pound of the item. In this question it says a pound of cheese costs 3.43, therefore each pound of cheese costs 3.43. We can also use the equation 3.43x where x represents the amount of pounds you are purchasing. Just multiply the two and you will get a cost for any amount (pounds) of cheese.

Two students are registered for the same class and attend independently of each other, student a 90% of the time and student b 70% of the time. the teacher remembers that on a given day at least one of them is in class. what is the probability that student a was in class that day
The probability of student A is 15/44
Given student A is 70% of time and student B is 60% of time
We need to find the probability of student A
Using formula of conditional probability is P(X/Y) = P(X and Y) / P(Y)
Here X = A and Y = A or B
Therefore,
P(A/A or B) = P(A and (A OR B) / P (A or B)
Now, There is none complement for at least 1
We know that Student A attends 70 % of time
So , his absence is 30% of the time .
Hence the probability of absence is 0.3
Now Considering B in the similar way
We get,
Probability of the absence is 0.4
They are both absent (0.3)(0.4)= 0.12
Here we can say that 12 % of time both are absent
So one or another present on that time is 88%
The probability of present of the time is 0.88
Now calculating the probability,
P(A/A or B) = P(A and (A OR B) / P (A or B)
= 0.3/0.88
= 30/88
= 15/44
Hence the Probability Of A is 15/44

Step-by-step explanation:
the formula for area of a parallelogram is a = bh
you know area (a) = 160 and height (h) = 4, so:
160 = 4 * b
divide both sides of this equation by 4,
b = 40

Suppose a simple random sample of size n is obtained from a population whose distribution is skewed right.
As we know, the distribution of sample means will be normally distributed even if the individual samples do not, according to the Central Limit Theorem, if the mean values for increasing sample sizes are determined.
Thus, as the sample size grows, the distribution of the sampled means becomes normally distributed.

Show work, can someone help me out having trouble with this problem
Answer:
Step-by-step explanation:
Formula
a = 9 / (f - 7)
Note
If you are going to try and isolate f, you must take the 7 with it, assuming that getting f to the left hand side will the your first step. It will be mine.
Solution
a = 9 / (f - 7) Multiply both sides by (f - 7) leave the brackets around (f - 7)
a(f - 7) = 9(f - 7)/(f - 7) Combine
a(f - 7) = 9 Remove the brackets
fa - 7a = 9 Add 63 to both sides
fa - 7a + 7a = 9 + 7a Combine
fa = 9 + 7a Divide by a
fa/a = (9 + 7a)/a Simplify
f = (9 + 7a)/a
Answer
f = (9 + 7a)/a
