The standard diameter of a golf ball is 42. 67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0. 002 mm. Which function could represent this situation?.
Answers
The absolute value function that could represent this situation is:
\(|D - 42.67| = 0.002\)
The absolute value function is defined by:
\(|x| = x, x \geq 0\)
\(|x| = -x, x < 0\)
It measures the distance of a point x to the origin.The diameter should be of 42.67 mm with an allowance of 0.002 mm. Thus, the absolute value of the difference between the diameter and of 42.67 should be of 0.002, that is:
\(|D - 42.67| = 0.002\)

What is the image of (x,y) after a translation of 3 units left and 7 units down?
Answers
Answer:
\((x + 3, y - 7)\)
Step-by-step explanation:
Given
\(Function = (x,y)\)
Translation:
\(Left = 3\ units\)
\(Down = 7\ units\)
Required
Determine the image of the function
Apply the first translation
\(Left = 3\ units\)
When function (x,y) is 3 units translated left, we add the units to the x value.
The new function becomes:
\((x,y) -> (x + 3, y)\)
Apply the second translation
\(Down = 7\ units\)
We subtract 7 units from the y value
\((x,y) -> (x + 3, y)\)
becomes:
\((x + 3, y) ->(x + 3, y - 7)\)
Hence:
The image of the function is:
\((x + 3, y - 7)\)

Two sides of a parallelogram are 530 feet and 120 feet. The measure of the angle between these sides is 138°. Find the area of the parallelogram to the nearest square foot.
Answers
Answer:
42,557 ft²
Step-by-step explanation:
Area of the parallelogram = 2×(Area of ∆)
Area of parallelogram = 2×(½×a×b×sin(θ))
Where,
a = 120 ft
b = 530 ft
θ = 138°
Plug in the values into the formula
Area of parallelogram = 2×(½×120×530×sin(138))
= 120×530×sin(138)
= 42,557 ft² (nearest square foot)

a $52 item is marked up 10% and then markdown 10% what is the final price
Answers
Answer: $51.48
Step-by-step explanation:
If a $52 item is marked up by 10%, its new price will be:
$52 + 10% of $52 = $52 + $5.20 = $57.20
Then, if this new price is marked down by 10%, the final price will be:
$57.20 - 10% of $57.20 = $57.20 - $5.72 = $51.48
Therefore, the final price of the item after the markup and markdown is $51.48.
Prove by induction:
5| (21^n+9)
Answers
It's kind of self-evident. Any power of 21 will have a 1 in the units place, and adding 9 to it makes it 0 and hence the number is divisible by 5.
To prove the claim by induction, first establish the base case. I assume \(n\in\Bbb N\), so for \(n=1\) we have
\(21^1 + 9 = 21 + 9 = 30\)
and of course 30 = 5×6 is divisible by 5.
Assume the claim is true for \(n=k\), that \(5 \mid 21^k + 9\). This means that for some integer \(\ell\), we can write
\(21^k + 9 = 5\ell\)
Now the induction step: when \(n=k+1\), we have
\(21^{k+1} + 9 = \bigg(21\times(21^k + 9) - 9\times21\bigg) + 9 \\\\ ~~~~~~~~~~~~~~ = 21\times5\ell - 9\times20 \\\\ ~~~~~~~~~~~~~~= 5\times(21\ell - 9\times4)\)
which is divisible by 5. QED

Answers
The Alternate Exterior Angles Theorem states that when a pair of parallel lines is intersected by a transversal, the pairs of alternate exterior angles formed on opposite sides of the transversal are congruent.
If line AB and line CD are parallel, and line EF intersects both lines at points G and H respectively, then the angles formed on opposite sides of line EF and on the exterior of the parallel lines are congruent.
The Alternate Exterior Angles Theorem states that when a pair of parallel lines is intersected by a transversal, the pairs of alternate exterior angles formed on opposite sides of the transversal are congruent.
In symbols, the theorem can be written as:
∠1 ≅ ∠4
where ∠1 and ∠4 are alternate exterior angles.

Step-by-step explanation:
a. Average rate of change for the height from 0 to 6.6 secs can be calculated using the formula, \( m = \frac{H(b) - H(a)}{b - a} \)
Thus,
Where,
\( a = 0, H(0) = 0 \)
\( b = 6.6, H(6.6) = 198 \)
Plug in the values into the formula:
\( m = \frac{198 - 0}{6.6 - 0} \)
\( m = \frac{198}{6.6} \)
\( m = 30 \)
b. Average rate of change for the height from 8.8 to 13.2 secs = tex] m = \frac{H(b) - H(a)}{b - a} \)
Where,
\( a = 8.8, H(8.8) = 44 \)
\( b = 13.2, H(13.2) = 0 \)
Plug in the values:
\( m = \frac{0 - 44}{13.2 - 8.8} \)
\( m = \frac{-44}{4.4} \)
\( m = -10 \)

Solve the quadratic by completing the square.x^2 + 14x = -69
Answers
We have to solve this equation by completing the square.
We have two terms from the quadratic equation: x² + 14x, so we can add the third term as:
\(\begin{gathered} x^2+14x=-69 \\ x^2+2(7)x+7^2=-69+7^2 \end{gathered}\)We add the same term to both sides of the equation to preserve the equality.
We now can continue solving the equation as:
\(\begin{gathered} x^2+2(7)x+49=-69+49 \\ (x+7)^2=-20 \\ x+7=\pm\sqrt{-20} \\ x=-7\pm\sqrt{-20} \end{gathered}\)This equation does not have solutions for x for the set of real values, as we have a square root of a negative number.
We can express the solution as complex numbers as:
\(\begin{gathered} x=-7\pm\sqrt{-20} \\ x=-7\pm\sqrt{20}i \\ x=-7\pm2\sqrt{5}i \end{gathered}\)Answer: the solutions for the equation are x = -7 - 2(√5)i and x = -7 + 2(√5)i.
What is the total amount required to pay off a loan of $16000 plus interest at the end of 8 years if the interest is compounded half- yearly and the rate is 14% p.a.
Answers
The total amount required to pay off the loan at the end of 8 years would be $37,784.09.
To calculate the total amount required to pay off a loan of $16,000 with an interest rate of 14% per annum compounded half-yearly over 8 years, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
where A is the total amount, P is the principal (or loan amount), r is the interest rate per annum, n is the number of times the interest is compounded per year, and t is the time period in years.
In this case, P = $16,000, r = 14%, n = 2 (since the interest is compounded half-yearly), and t = 8 years.
Plugging in the values, we get:
A = $16,000(1 + 0.14/2)^(2*8)
= $37,784.09
Therefore, the total amount required to pay off the loan at the end of 8 years would be $37,784.09, including the principal amount of $16,000 and the accumulated interest.

researcher created three groups based on participants BMI: normal weight, overweight and obese. The hypothesis being tested is that the three groups differ in the mean number of artificially sweetened drinks consumed weekly. Which statistical test might the researcher use, assuming a reasonable normal distribution of values?
A repeated measures ANOVA
An independent group t test
One way ANOVA
A chi-squared test
Answers
To test the hypothesis of mean differences in artificially sweetened drink consumption among BMI groups, assuming a normal distribution, the researcher might use a one-way ANOVA.
The one-way ANOVA compares the means of three or more independent groups and determines if there are statistically significant differences among them. In this case, the BMI groups (normal weight, overweight, and obese) represent the independent groups, and the number of artificially sweetened drinks consumed is the dependent variable. By conducting a one-way ANOVA, the researcher can assess if there are significant differences in mean consumption among the BMI groups and draw conclusions regarding their hypothesis.

Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.61 and a standard deviation of 0.44. Using the empirical rule, what percentage of the students have grade point averages that are at least 3.49? Please do not round your answer.
Answers
Using the empirical rule about 2.5% of the students have a grade point average that is at least 3.49.
What is empirical rule?
The empirical rule, also known as the 68-95-99.7 rule, states that for a bell-shaped distribution, approximately:
68% of the data falls within one standard deviation of the mean.
95% of the data falls within two standard deviations of the mean.
99.7% of the data falls within three standard deviations of the mean.
To find the percentage of students with a grade point average of at least 3.49, we can use the formula for z-scores:
z = (x - μ) / σ
Where x is the value of interest (in this case, 3.49), μ is the mean (2.61), and σ is the standard deviation (0.44).
z = (3.49 - 2.61) / 0.44
z = 1.989
So a student with a GPA of 3.49 is 1.989 standard deviations above the mean.
Using the empirical rule, we know that approximately 95% of the data falls within two standard deviations of the mean.
Since a z-score of 1.989 is within two standard deviations of the mean, we can estimate that the percentage of students with a GPA of at least 3.49 is approximately -
(100% - 95%) / 2 = 2.5%
Therefore, the percentage of students is 2.5%.
