2. 0
3. See explanation
Step-by-step explanation:
Solving (1):
From the list of given options, Option C. Rational Algebraic Expression answers the question.
And it is always of the form P/Q where P and Q are polynomials
Take for instance
P = x² - x + 2 and Q = x² + 2x - 4
P/Q = (x² - x + 2)/(x² + 2x - 4)
The above expression is a perfect example of a Rational Algebraic Expression
Solving (2): The denominator of a rational algebraic expression must not equal 0
Hence, option A answers the question
Solving (3): The options are missing.

Statistical significance at the 0.01 level is __________ than significance at the 0.05 level .
a. less informative
b. more difficult to achieve
c. easier to achieve
d. less costly
Answers
Answer:
d. less costly
Step-by-step explanation:
Statistical significance level is the probability of rejecting the null hypothesis. Statistical significance at the 0.05 level is the standard level for rejecting the null hypothesis.
A significance of 0.01 shows that there is strong evidence to conclude that the null hypothesis is not true. A 0.05 significance is the most used level while 0.01 is used when multiple tests are conducted or when the researcher is not so sure if the null hypothesis should be rejected. It increases the amount of evidence required to prove the null hypothesis and it also reduces the possibility of obtaining a false positive.

Flight Path of a Bird
In this activity, you'll use quadratic equations to model situations and interpret the solutions to the equation
The flight path of a bird can be represented by this equation, where x represents the horizontal distance, in feet, from a tree
branch and y represents the height, in feet, relative to the ground.
y = 2x2 - 8x + 10
Part A
Question
Rewrite the equation modeling the path of the bird in vertex form by completing the square,
Substitute the values of a, h, and k to complete the equation.
Answers
Answer:
The equation modeling the path of the bird in vertex form is [tex]y=2(x-2)^2+2[/tex]
Step-by-step explanation:
General vertex form equation: [tex]f(x) = a(x-h)^2 + k[/tex]
where (h,k) is the vertex
The flight path of a bird can be represented by this equation: [tex]y = 2x^2 - 8x + 10[/tex]
To convert the equation in vertex form
Completing the square :
[tex]y = 2(x^2 - 4x + 5)\\y = 2(x^2 - 4x + 5 +(2)^2-(2)^2)\\y = 2(x^2 - 4x + 5 +(2)^2-4)\\y = 2((x-2)^2-4+5)\\y = 2((x-2)^2+1)\\y=2(x-2)^2+2[/tex]
Where:
(h,k)=(2,2)
a=2
Hence the equation modeling the path of the bird in vertex form is [tex]y=2(x-2)^2+2[/tex]

Step-by-step explanation:
A tortoise challenged a hare to a 100-meter race on a track. The tortoise negotiated a 60-meter head start with the hare. When they passed their respective starting points the hare was running at a constant speed of 3.6 meters per second and the tortoise was crawling at a speed of 0.7 meters per second. (They both maintained these speeds for the entire race.) Our goal is to determine who won the race. Take out a piece of paper and read the above problem statement again. In a couple of sentences, describe how you might determine who won the race. Construct a drawing to represent the 100-meter length of the track. Then place the tortoise and hare's starting points on the track. Define the variable t to represent the number of seconds since the start of the race.
Answers
Answer:
Hare wins the race
Step-by-step explanation:
Length of track = 100 m
Let t represent the number of seconds in completing the race.
Speed of tortoise = 0.7 m/s
Distance covered by tortoise in t seconds = Speed \times time = 0.7t
We are given that The tortoise negotiated a 60-meter head start with the hare.
So, Distance covered by tortoise in t seconds = 60+0.7t
Speed of hare = 3.6 m/s
Distance covered by hare in t seconds = 3.6 t
Now
3.6t = 100
[tex]t=\frac{100}{3.6}[/tex]
t=27.77
60+0.7t=100
[tex]t=\frac{100-60}{0.7}[/tex]
t=57.14
So, Hare took less time
So, Hare wins the race

Answer:
P (S∩E) = 0.1591
Step-by-step explanation:
Let the stockholders be donated by S then the P (s)= 0.43
Let the stockholders having some degree be donated by D then the P (d)= 0.75
Let the American having some college degree be donated by E then the
P (E)= 0.37
As the events are independent their joint probability can be found by multiplying the individual probabilities
P (S∩E) = P(s) . P (E)= 0.43 * 0.37= 0.1591
If QS bisects ZRQP, mZRQS =

find mZRQS.
Answers
Answer:
66°
Step-by-step explanation:
[tex]\because \overrightarrow{QS} \: bisects\: \angle RQP\\\\
\therefore m\angle RQS = m\angle SQP\\\\
\therefore 2x + 10 = 3x - 18\\\\
\therefore 18 + 10 = 3x - 2x\\\\
\therefore 28 = x\\\\
\therefore x = 28\\\\
m\angle RQS = (2x + 10)\degree \\\\
m\angle RQS = (2\times 28+ 10)\degree \\\\
m\angle RQS = (56+ 10)\degree \\\\

A DVD rental store wants to know what proportion of its customers are under age 21. A simple random sample of 400 customers was taken, and 280 of them were under age 21. Presume that the true population proportion of customers under age 21 is 0.68. What is the probability that the sample proportion \hat{p} is within 0.03 of the true proportion of customers who are under age 21 that is , what is the probability that \hat{p} is between 0.68 - 0.03 and 0.68 0.03
Answers
Answer:
The sample proportion [tex]\hat{p}[/tex] is within 0.03 of the true proportion of customers who are under age 21 is 0.803
Step-by-step explanation:
Total no. of customers = n = 400
We are given that the true population proportion of customers under age 21 is 0.68.
So, p =0.68
q=1-p=1-0.68=0.32
Standard deviation =[tex]\sqrt{\frac{pq}{n}}=\sqrt{\frac{0.68 \times 0.32}{400}}= 0.023[/tex]
We are supposed to find the probability that the sample proportion [tex]\hat{p}[/tex] is within 0.03 of the true proportion of customers who are under age 21 that is , what is the probability that [tex]\hat{p}[/tex]is between 0.68 - 0.03 and 0.68+ 0.03
[tex]P(0.65 < X < 0.71) = P((\frac{0.65-0.68}{0.0233}) < Z < (\frac{0.71-0.68}{0.0233}))[/tex]
Using Z table
[tex]= P(-1.2875 < Z < 1.2875)= 0.803[/tex]
Hence the sample proportion [tex]\hat{p}[/tex] is within 0.03 of the true proportion of customers who are under age 21 is 0.803
