A variable star is one whose brightness alternately increases and decreases. For one such star, the time between periods of maximum brightness is 4.5 days, the average brightness (or magnitude) of the star is 5.4, and its brightness varies by ±0.30 magnitude. Find a function that models the brightness of the star as a function of time (in days), t. (Assume that at t = 0 the brightness of the star is 5.4 and that it is increasing.)
Answer:
f(t) = 5.4 + 0.3sin (2π/4.5t)

A one-tailed hypothesis test with the t statistic Antisocial personality disorder (ASPD) is characterized by deceitfulness, reckless disregard for the well-being of others, a diminished capacity for remorse, superficial charm, thrill seeking, and poor behavioral control. ASPD is not normally diagnosed in children or adolescents, but antisocial tendencies can sometimes be recognized in childhood or early adolescence. James Blair and his colleagues have studied the ability of children with antisocial tendencies to recognize facial expressions that depict sadness, happiness, anger, disgust, fear, and surprise. They have found that children with antisocial tendencies have selective impairments, with significantly more difficulty recognizing fearful and sad expressions. Suppose you have a sample of 40 16-year-old children with antisocial tendencies and you are particularly interested in the emotion of disgust. The average 16-year-old has a score on the emotion recognition scale of 11.80. (The higher the score on this scale, the more strongly an emotion has to be displayed to be correctly identified. Therefore, higher scores indicate greater difficulty recognizing the emotion). Assume that scores on the emotion recognition scale are normally distributed.
The null hypothesis is that your sample of children with antisocial tendencies would have no more difficulty recognizing emotion than the general population of 16-year-olds. Stated using symbols:_________. This is a __________ tailed test. Given what you know, you will evaluate this hypothesis using a________ statistic.
Step-by-step explanation
The answers in bold is what was required from the question.
the null hypothesis using symbol:-
H₀ : μ = 11.80
the alternative hypothesis using symbol:-
H₁: μ ≠ 11.80
This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.
Alpha level = 0.05
Sample size = n
Degree of freedom = n-1 = 40-1 = 39
To use the t distribution we will have to find the critical value from the t table this value is 1.685
But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error
What is the domain of the relation?
The producer believes that there is more variety in people's appreciation of comedies, and so he assumes that the two population standard deviations are not equal in this situation. Calculate the test statistic (t) for this test. Give your answer to 3 decimal places.

From the question we are told that
The first sample mean is [tex]\= x_1 = 71.1[/tex]
The first standard deviation is [tex]\sigma _1 = 19.4[/tex]
The second sample mean is [tex]\= x_2 = 63.4[/tex]
The second sample deviation is [tex]\sigma_2 = 10.5[/tex]
The first sample size is [tex]n_1 = 55[/tex]
The second sample size is [tex]n_2 = 46[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\= x_1 - \= x_2 }{ \sqrt{\frac{s_1^2 }{n_1} +\frac{s_2^2 }{n_2} } }[/tex]
=> [tex]t = \frac{71.1 - 63.4 }{ \sqrt{\frac{19.4^2 }{55} +\frac{10.5^2 }{46} } }[/tex]
=> [tex]t = 2.51 [/tex]

At 8 A.M. the temperature was-14 °F. By noon, the temperature was 12 °F. How many degrees did it change? *
Answer:
I think that to go to the temperature you you can draw a straight line then on one side write negative the other side positive that the centre write 0 then locate -14 and 12 so negative 14 will fall on the negative side and 12 will fall on the positive side then count from -14 up to positive 12 and you'll find that it changed by 26°
Which ordered pairs are solutions to the equation x + 6y = 4?
Answer:
24
Step-by-step explanation:
For example, the ordered pair x + 6y = 4 answer is 24
The required ordered pair is the solution of the equation x + 6y = 4 is (1, 1/2).
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
Given equation,
x + 6y = 4,
In order to determine the ordered pair for the given equation, we must assign the value of the one variable, so the satisfied value of the other value of the independent variable will be determined, and the pair will be said to be the required ordered pair.
Now,
Put x = 1
1 + 6y = 4
y = 4 -1 / 6
y = 1/2
Thus, the required ordered pair is the solution of the equation x + 6y = 4 is (1, 1/2).

and the other measures
2
x

7
. Find the value of x and the measure of the smaller angle.
Answer:
x = 35°77Step-by-step explanation:
Supplementary angles add up to 180°
3x - 2° + 2x + 7° = 180°5x + 5° = 180°5x = 175°x = 35°Angles
3*35° - 2° = 105° - 2° = 103°and
180° - 103° = 77°Answer:
x = 35
77 degrees
Step-by-step explanation:
Supplementary angles mean that two angles add up to measure 180 degrees.
Solve for x.
(3x - 2) + (2x + 7) = 180
~Combine like terms
5x + 5 = 180
~Subtract 5 to both sides
5x = 175
~Divide 5 to both sides
x = 35
Angle 1:
3x - 2
3(35) - 2
105 - 2
103 degrees
Angle 2:
2x + 7
2(35) + 7
70 + 7
77 degrees
103 > 77
The smaller angle is 77.
Best of Luck!

Because of recent tax law changes, Ms. Benoit’s tax rate for next year will decrease to 25 percent. Based on a static forecast, how much less revenue will the government collect from Ms. Benoit is a self-employed architect who earns $300,000 annual taxable income. For the past several years, her tax rate on this income has been 35 percent. Because of recent tax law changes, Ms. Benoit’s tax rate for next year will decrease to 25 percent. a) Based on a static forecast, how much less revenue will the government collect from Ms. Benoit next year? b) How much less revenue will the government collect from Ms. Benoit next year if she responds to the rate decrease by working more hours and earning $375,000 taxable income? c) How much less revenue will the government collect from Ms. Benoit next year if she responds to the rate decre
Answer:
a
[tex]Y = \$ 30000[/tex]
b
[tex]Y = \$ 11250 [/tex]
c
[tex]X = \$ 36250 [/tex]
Step-by-step explanation:
From the question we are told that
The annual taxable income is [tex]A = \$ 300,000[/tex]
The tax rate for next year is [tex]r = 0.25[/tex]
The present tax rate is [tex]R = 0.35[/tex]
Generally the present amount of tax collected from Ms Benoit is
[tex]K = A * R[/tex]
[tex]K = 300000 * 0.35 [/tex]
=> [tex]K = \$105000 [/tex]
Generally the amount of tax collected from Ms Benoit nest year is
[tex]B = A * r[/tex]
[tex]B = 300000 * 0.25 [/tex]
=> [tex]B = \$75000 [/tex]
The reduction in the tax amount is mathematically represented as
[tex]Y = K - B[/tex]
=> [tex]Y = 105000 - 75000[/tex]
=> [tex]Y = \$ 30000[/tex]
Generally the tax amount of next year when the income is $375,000 is mathematically represented as
[tex]M = 375 000 * r[/tex]
=> [tex]M = 375 000 * 0.25[/tex]
=> [tex]M = \$ 93 750 [/tex]
The reduction in the tax amount is mathematically represented as when the income for next year is $375,000
[tex]Z = K - M[/tex]
=> [tex]Z = 105000 -93 750 [/tex]
=> [tex]Z = \$ 11250 [/tex]
Generally the tax amount of next year when the income is $275,000 is mathematically represented as
[tex]U = 275,000 * r[/tex]
=> [tex]U = 275 000* 0.25[/tex]
=> [tex]M = \$ 68 750 [/tex]
The reduction in the tax amount is mathematically represented as when the income for next year is $275,000
[tex]X = K - M[/tex]
=> [tex]X = 105000 -68 750 [/tex]
=> [tex]X = \$ 36250 [/tex]
