Determine the amplitude or period as requested. Period of a y = - 1/3 * sin x - 1/3 pi/3 1/3 d 2pi
Answer:
[tex]Period = 2\pi[/tex]
Step-by-step explanation:
Given
[tex]y = -\frac{1}{3} * \sin(x - \frac{1}{3})[/tex]
Required
Determine the period
A sine function is represented as:
[tex]y =A \sin(Bx + C) + D[/tex]
Where
[tex]Period = \frac{2\pi}{B}[/tex]
By comparing:
[tex]y =A \sin(Bx + C) + D[/tex] and [tex]y = -\frac{1}{3} * \sin(x - \frac{1}{3})[/tex]
[tex]Bx = x[/tex]
So:
[tex]B = 1[/tex]
So, we have:
[tex]Period = \frac{2\pi}{B}[/tex]
[tex]Period = \frac{2\pi}{1}[/tex]
[tex]Period = 2\pi[/tex]
Hence, the period of the function is [tex]2\pi[/tex]

Answer:
Perimeter of the summer camp = 38 units
Step-by-step explanation:
Distance between P(5, 14) and Q(8, 14) = 8 - 5
= 3 units
Distance between Q(8, 14) and R(8, 2) = 14 - 2
= 12 units
Distance between R(8, 2) and S(1, 2) = 8 - 1
= 7 units
Distance between S(1, 2) and T(1, 8) = 8 - 2
= 6 units
Distance between T(1, 8) and U(5, 8) = 5- 1
= 4 units
Distance between U(5, 8) and P(5, 14) = 14 - 8
= 6 units
Therefore, perimeter of the summer camp = 3 + 12 + 7 + 6 + 4 + 6
= 38 units
The combined SAT scores for the students at a local high school are normally distributed with a mean of 1527 and a standard deviation of 295. The local college includes a minimum score of 1380 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement
Answer:
69.15% of students from this school earn scores that satisfy the admission requirement.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 1527 and a standard deviation of 295.
This means that [tex]\mu = 1527, \sigma = 295[/tex]
The local college includes a minimum score of 1380 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement?
The proportion is 1 subtracted by the pvalue of Z when X = 1380. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1380 - 1527}{295}[/tex]
[tex]Z = -0.5[/tex]
[tex]Z = -0.5[/tex] has a pvalue of 0.3085
1 - 0.3085 = 0.6915
0.6915*100% = 69.15%
69.15% of students from this school earn scores that satisfy the admission requirement.
Solve m − hp = d for p
p=−d+m/h
Step by step:
m−hp=d
−hp+m+−m=d+−m
−hp=d−m
-hp/-h=d-m/-h
p=-d+m/h
The expression solved for p is [tex]p = \frac{m - d}{h}[/tex].
What is a variable in equation?It is the unknown value in a set of range. Variable always represent a number.
Given that,
m − hp = d
There are 4 variables. If we want to solve the above equation for p, take p at one side of the equation and other variables to the other side:
[tex]ph ={m - d}[/tex]
[tex]p = \frac{m - d}{h}[/tex]
Hence the final equation for p is [tex]p = \frac{m - d}{h}\\[/tex].

Use the information and table to answer the following questions.
A sociologist was interested in determining if there was a relationship between the age of a young adult (18 to 35 years old) and the type of movie preferred. A random sample of 93 adults revealed the following data. Use a Chi-Square independence test to determine if age and type of movie preferred are independent at the 5% level of significance.
18-23 years old 24-29 years old 30-35 years old Totals
Drama 8 15 11 34
Science Fiction 12 10 8 30
Comedy 9 8 12 29
Totals 29 33 31 93
1. State the Null Hypothesis
A) Age and type of movie preferred are not independent.
B) Age and type of movie preferred are independent
C) Age and type of movie preferred are not the same
D) Age and type of movie preferred are related.
E) Cannot be determined.
2. State the alternative hypothesis.
A). Age and type of movie preferred are dependent.
B) Age and type of movie preferred are independent.
C) Age and type of movie preferred are not related
D) Age and type of movie preferred are superior.
E) Cannot be determined.
Answer:
1. B) Age and type of movie preferred are independent
2.A). Age and type of movie preferred are dependent.
Step-by-step explanation:
1. State the Null Hypothesis
B) Age and type of movie preferred are independent
2. State the alternative hypothesis.
A). Age and type of movie preferred are dependent.
This is chi square independence test therefore we will test the independence of the two factors age and the type of movie preferred.
The null hypothesis is formulated as
Age and type of movie preferred are independent
against the claim
Age and type of movie preferred are dependent.

Transform the given function f(x) as described. f ( x ) = x 3 Translate right 2 units Translate up 3 units
Answer:
Step-by-step explanation:
f(x) = x^3
To get this to move right, you must do the opposite to what you think you should do.
f(x) =(x - 2)^3.
That looks like it should go left, but it doesn't. It does go right. Suppose you want to know where (0,0) has moved to. If you put x = 2 into x - 2 you get a value of y = 0. That's where the point 0,0 has moved to. It has gone to 2,0
Now you want f(x) to move up 3 units.
f(x) = (x - 2)^3 + 3 The y value lf x = 2 moves up 3 units
Let's see if this is correct.
If you look at the graphs,
The red one is y = x^3The blue one is y = (x - 2)^3The green one is y = (x - 2)^3 + 3The point 0,0 has been marked for the blue one as it shifts to the right and becomes (2,0) and up 3 in the green graph.

If f(x) = x + 1 and g(x) = 2x - 7, which expression is equivalent to [fog|(3)?
Answer and Step-by-step explanation:
First, we plug in the value of 3 for x in g(x), then we plug the answer os g(x) into the value of x in f(x).
g(3) = 2(3) - 7
Multiply 2 by 3, then subtract 7.
g(3) = 6 - 7
g(3) = -1
Now, we plug -1 for x in f(x).
f(g(3)) = f(-1) = -1 + 1
f(-1) = 0
The value of f(g(3)) is 0.

Step-by-step explanation:
15 is 60% of what number?
15 is 60% of the number 25
To find the number of which 15 is 60%, we can set up the following equation:
0.60 * x = 15
Here, x represents the unknown number.
To solve for x, we divide both sides of the equation by 0.60:
x = 15 / 0.60
Evaluating the division:
x = 25
Therefore, 15 is 60% of 25.
