Which of these questions is most likely to result in response bias? A. "What do you think of this TV show?" B. "What is your opinion of this TV show?" C. "How do you like this great new TV show?" D. "How do you feel about this TV show?"
Answer: C. "How do you like this great new TV show?"
The term "great" put in there skews the question to make people think the show is great, when it may not be. So people may have a tendency to say they really like the show when they may not.
Or perhaps they may like the show (somewhat) but the fact that they can sense the bias built into the question makes them decide to say opposite and say they don't like the show. Maybe this sort of scenario would have them rebel in a way.
Either way, the use of "great" is likely to alter the opinion of people answering the question.

Taylor opened a savings account with $425. After 2 years, the total interest earned was $10.20. What was the annual interest rate?
Answer:
R = 1.2%
Step-by-step explanation:
Given the following data;
Principal = 425
Time = 2
Simple interest = 10.20
To find the annual interest rate;
Mathematically, simple interest is calculated using this formula;
\( S.I = \frac {PRT}{100} \)
Where;
S.I is simple interest. P is the principal. R is the interest rate. T is the time.Substituting into the equation, we have;
\( 10.20 = \frac {425*R*2}{100} \)
\( 10.20 = \frac {850R}{100} \)
Cross-multiplying, we have;
\( 1020 = 850R \)
\( R = \frac {1020}{850} \)
R = 1.2%
Therefore, the annual interest rate is 1.2 percent.
If you are using algebra tiles to factor a trinomial of the form ax2 + bx + c, when would you need to bring in zero pairs? Why? ANSWER ASAP ON EDGE
Answer:
*Sample Response:* If the value of c is negative, you would need zero pairs to model the factorization of the polynomial. The x-tiles on the board determine what the constants are in the factors. The product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. Opposite signs on the constants will result in a negative value for c when multiplying the factors.

How to find the (r) or difference in this scenario:
Aliens Away is a new video game where a player must eliminate a certain number of aliens on the screen by scaring them with an adorable house cat. When James plays the game, he eliminates 64 aliens in the first level and 216 aliens in the fourth level. If the number of aliens are destroyed in a geometric sequence from one level to the next, how many total aliens will James have wiped out by the end of the sixth level?
It is given that it is a geometric sequence, if I am not mistaken it is the explicit formula.
IF YOU COULD PLASE EXPLAIN:)
Total number of aliens James have wiped out by the end of the sixth level is 1330
The number of aliens eliminated in first level a = 64
The number of aliens eliminated in the fourth level = 216
The sequence is in geometric sequence
The nth term of the geometric sequence is
\(a_n=ar^{n-1}\)
The fourth term is 216
216 = \(64r^3\)
\(r^{3}\) = 216/64
r = 3/2
Then we have to find the total alien James killed by the end of sixth level
Sum of n terms = \(\frac{a(r^n-1)}{r-1}\)
Substitute the values in the equation
= \(\frac{64(1.5^6-1)}{1.5-1}\)
= 665/0.5
= 1330
Hence, total number of aliens James have wiped out by the end of the sixth level is 1330

A leasing agreement is for 5 years. A sum of £10,000 must be paid at the beginning of the first year, to be followed by four equal payments of £x at the beginning of years two, three, four and five. At a discount rate of 8 per cent, the present value of the four equal payments is £26,496. Compute the total amount to be paid during the lease period.
The total amount paid during the lease period is £45,665.64.
To find the total amount paid during the lease period, we need to add the initial payment of £10,000 to the present value of the four equal payments, which can be calculated using the present value formula:
PV = FV / (1 + r)^n
Where PV is the present value, FV is the future value, r is the discount rate, and n is the number of periods. In this case, the present value of the four equal payments is £26,496, the discount rate is 8%, and the number of periods is 4. We can solve for the future value by rearranging the formula:
FV = PV × (1 + r)^n
Plugging in the given values, we get:
FV = £26,496 × (1 + 0.08)^4
FV = £26,496 × 1.34
FV = £35,664.64
This is the total future value of the four payments. To find the total amount paid during the lease period, we need to add this to the initial payment of £10,000. Therefore, the total amount paid during the lease period is:
£35,664.64 + £10,000 = £45,665.64
Therefore the total amount paid during the lease period is £45,665.64.

A board 60 in. long is cut into two parts so that the longer piece is 5 times the shorter. What is the lengths of the two pieces
The shorter piece is ___ inches
The longer piece is ___ inches
Step-by-step explanation:
x = length of longer piece
y = length of shorter piece
x + y = 60
x = 5y
so, we can use the identity of the second equation in the first equation ;
5y + y = 60
6y = 60
y = 10 in
x = 5y = 5×10 = 50 ft
the shorter piece is 10 inches long.
the longer piece is 50 inches long.
Which of the following is an improper form of the null and alternative hypotheses? a. H_0: mu lessthanorequalto mu_0 and H_a: mu > mu_0 b. H_0L: mu = mu_0 and H_a: mu = mu_0 c. H_0: mu < mu_0 and H_a: mu greaterthanorequalto mu_0 d. H_0: mu greaterthanorequalto mu_0 and H_a: mu < mu_0
They are known as the two types of first is null hypothesis and the second is alternative hypothesis. These two hypotheses bear opposite viewpoints.
H0: also known as null hypothesis: It is a statement about the population that either is taken to be true or is used to put forth an argument until it can be shown to be incorrect behind a reasonable doubt.
Ha: also known as the alternative hypothesis: It is a state about the population that is contradictory to H0 and what we conclude when we reject H0.
H0 every time has a symbol with an equal in it. It never has a symbol with an equal in it. The option of the symbol depends on the wording of the hypothesis test.
Yet, be aware that many researchers use = in the null hypothesis, even with > (greater) or < (less) as the symbol in the alternative hypothesis.
We can accept this practice because we only decide to reject or not reject the null hypothesis.

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a larger class size, which school is a better choice for you? Explain your reasoning. (1 point)
Part A: The measures of center in Mountain View School, mean = 4.75, median = 4.5 and Bay Side School, mean = 5.5, median = 4.5
Part B: The measures of variability: Mountain View School, Range= 9 IQR= 4, Bay Side School, Range= 10 IQR= 3
Part C: Bay Side School would be the better choice.
Part A: Measures of Center
To calculate the measures of center, we will determine the mean and median for each school.
Mountain View School:
Mean = (0 + 5 + 6 + 8 + 9 + 8 + 2 + 0) / 8 = 38 / 8 = 4.75
Median = (4 + 5) / 2 = 4.5
Bay Side School:
Mean = (10 + 2 + 4 + 5 + 6 + 8 + 8 + 7 + 6 + 5 + 5 + 4 + 4 + 3 + 1 + 0) / 16 = 88 / 16 = 5.5
Median = (4 + 5) / 2 = 4.5
Part B: Measures of Variability
To calculate the measures of variability, we will determine the range and interquartile range (IQR) for each school.
Mountain View School:
Range = 9 - 0 = 9
IQR = (6 - 2) = 4
Bay Side School:
Range = 10 - 0 = 10
IQR = (6 - 3) = 3
Part C: Choice based on Class Size
If you are interested in a larger class size, Bay Side School would be the better choice. The mean class size at Bay Side School is 5.5, while at Mountain View School it is 4.75. The range of class sizes at Bay Side School is also larger (10) compared to Mountain View School (9). This indicates that there is a greater variation in class sizes at Bay Side School, providing a higher likelihood of finding larger class sizes. However, it's important to consider other factors such as teaching quality, resources, and overall educational environment before making a final decision.

find the domain and range of each f(x)^ * = 1 + x ^ 2
The function f(x)* = 1 + x^2 is defined for all real numbers x, so the domain is all real numbers, or (-∞, ∞).
How to explain the domainIn determining the function's output values, one must consider its collection of feasible results to extract the range. Reviewing f(x)* exhibits a minimum value of 1 due to x^2 being perpetually non-negative, while adding another factor merely preserves positivity.
Concurrently as x skyrockets, so too does the value of f(x)* given that approaching infinity generates infinitely larger powers than any constant coefficient subordinated by it. Consequently, the overall range of f(x)* becomes [1, ∞), enwrapping all feasible solutions equivalent or superior to 1.
