Answer:
x = 30°
y = 70°
z = 80°
Step-by-step explanation:
[tex]x = 180 \degree - 150 \degree = 30 \degree \\ \\ z = 180 \degree - 100 \degree = 80 \degree \\ \\ y = 180 \degree - (30 \degree + 80 \degree ) \\ \\ y = 180 \degree -110 \degree \\ \\ y = 70 \degree[/tex]
Consider the functions k(x) = x + 1, m(x) = x - 4, n(x) = x + 5, and f(x) = k(x) • m(x) · n(x). a. Determine the degree of the function f(x).
Answer:
[tex]Degree = 3[/tex]
Step-by-step explanation:
Given
[tex]k(x) = x + 1[/tex]
[tex]m(x) = x - 4[/tex]
[tex]n(x) = x + 5[/tex]
[tex]f(x) = k(x) * m(x) * n(x)[/tex]
Required
The degree of f(x)
First, calculate f(x)
[tex]f(x) = k(x) * m(x) * n(x)[/tex]
[tex]f(x) = (x +1) * (x - 4) * (x + 5)[/tex]
Expand
[tex]f(x) = (x +1) * (x^2 - 4x + 5x - 20)[/tex]
[tex]f(x) = (x +1) * (x^2 + x - 20)[/tex]
Further Expand
[tex]f(x) = x^3 + x^2 - 20x +x^2 + x - 20[/tex]
Collect like terms
[tex]f(x) = x^3 + x^2 +x^2 - 20x + x - 20[/tex]
[tex]f(x) = x^3 + 2x^2 - 19x- 20[/tex]
The degree of f(x) is the highest power of x.
Hence:
[tex]Degree = 3[/tex]

Step-by-step explanation:
A researcher conducted a hypothesis test to see if students on average spend more than 1 hour per homework assignment. The level of significance, a, selected was 0.05. This means that if on average they do spend exactly 1 hour per assignment, then there is a 5% chance that the erroneous conclusion will be made that students spend on average more than 1 hour per assignment.
a. Trueb. False
Answer:
a. True
Step-by-step explanation:
By ∝= 5% we mean that there are about 5 chances in 100 of incorrectly rejecting a true null hypothesis. To put it in another way , we say that we are 95% confident in making the correct decision.
In the given question the null hypothesis is
H0: u ≤ 1 hour and Ha: u > 1 hour
So there is a 5% chance that the erroneous conclusion will be made that students spend on average more than 1 hour per assignment.
The given statement is true.

Find the sum of the first 20 terms of the sequence {4,10,16,22,...} step by step
Answer:
All terms separated by 6 so #20 = 4 + 6 * 19 = 118
(if the first term were 6 instead of 4 the 20th would be 120)
Also, #10 = 58 and #11 = 64 (you can use the same reasoning)
The 1st and 20th term add to 4 + 118 = 122
The 2nd and 19th add to 10 + 112 = 122
Likewise 10th and 11th add to 58 + 64 = 122
So 10 * 122 = 1220

A random sample of 500 registered voters in Phoenix is asked if they favor the use of oxygenated fuels year-round to reduce air pollution. If more than 313 voters respond positively, we will conclude that at least 60% of the voters favor the use of these fuels.
Required:
a. Find the probability of type I error if exactly 60% of the voters favor the use of these fuels.
b. What is the type II error probability β if 75% of the voters favor this action?
Answer:
[tex]\alpha=0.11767[/tex]
[tex]\beta=0[/tex]
Step-by-step explanation:
From the question we are told that:
Population size size [tex]N=500[/tex]
Sample mean [tex]n=313[/tex]
Null hypothesis [tex]H_0:P=0.6[/tex]
Alternative hypothesis[tex]H_a:P>0.6[/tex]
Generally the equation for for P value is mathematically given by
[tex]P=\frac{n}{N}[/tex]
[tex]P=\frac{313}{500}[/tex]
[tex]P=0.6[/tex]
Generally the mean [tex]\=x[/tex] is mathematically given by
[tex]\=x=np\\\=x=500*0.6[/tex][tex]\=x=300[/tex]
Generally the standard deviation [tex]\sigma[/tex] is mathematically given by
[tex]\sigma=\sqrt{npq}[/tex]
[tex]\sigma=\sqrt{500*0.6*(1-0.6)}[/tex]
[tex]\sigma=10.95[/tex]
a)
Generally the probability of Type_I error [tex]P(X>313)[/tex] is mathematically given as
[tex]P(X>313)=P(\frac{x-\mu}{\sigma}>\frac{313-300}{10.95} )[/tex]
[tex]P(X>313)=P(z>1.187 )[/tex]
Therefore using z table
[tex]\alpha=0.11767[/tex]
b)
Null hypothesis [tex]H_0:P=0.75[/tex]
Alternative hypothesis[tex]H_a:P>0.75[/tex]
Generally the probability of Type_II error [tex]P(X<313)[/tex] is mathematically given as
[tex]P=0.75,n=500\\q=1-0.75\\q=0.25[/tex]
Generally the mean [tex]\=x'[/tex] is mathematically given by
[tex]\=x'=500*0.75[/tex]
[tex]\=x'=500*0.75[/tex]
[tex]\=x'=375[/tex]
Generally the standard deviation [tex]\sigma[/tex] is mathematically given by
[tex]\sigma=\sqrt{npq}[/tex]
[tex]\sigma=\sqrt{500*0.75*(1-0.75)}[/tex]
[tex]\sigma=9.68[/tex]
Therefore
[tex]P(X<313)=P(\frac{x-\mu}{\sigma}<\frac{313-375}{9.68} )[/tex]
[tex]P(X<313)=P(z<-6.405)[/tex]
Therefore from standard normal table
[tex]P(X<313)=0[/tex]
[tex]\beta=0[/tex]

The time it takes for the friend in the left seat to move upward, downward, and then back to the initial position is 4 seconds.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Two friends are sitting on a seesaw at the park. The height, h(t), of the left seat, in inches above the ground, is modeled by a sine function.
Let t represent the time, in seconds, since the friends started seesawing.

The group has to come back to this position after moving upward and downward. The time it takes to reach upward is,
[tex]f(48)=t_{up}\\f(48)=1[/tex]
The time it takes to reach downward after going upward is,
[tex]f(0)=t_{down}\\f(0)=3[/tex]
Coming back to initial potion,
