How many distinguishable 5-letter combinations are possible of the letters of the word TIGHT?
A. 40
B. 60
C. 72
D. 120
Answer:
A. 40 combinations
we have 8 x 5 = 40
Step-by-step explanation:
Would be 60 as 3 letter words with 5 letters.
The logic is that all letters are being used to their maximum and with numbers 3 within 5 or 5 within 5 the maximum that cna be used is 12 rotation for 3 per letter or 8 rotaion for 5. Then we have 5 rotations = 60 for 3 and 40 for 5. Another logic is the many combinations can you make from the numbers 1 2 3 4 5 not multiplying?
The rearrangement of 5 figure numbers will be 5x4x3x2x1 which is 120 combinations, when you don't repeat a number.
We see that 4+3 +2+1 = 10 and shows less than 5 number combinations at 120, and then we have 5
5:10 ratio = 5/15 = 1/3
This = 1/3 of 120 =40
Then we find answer is 40 as compact 5 letter words from the word tight.

two data sets have similar variabilities. suppose the measures of center of the data sets differ by 4 times the measure of variation. describe the visual overlap of the data.
Answer:
When two data sets have similar populations, the value of difference measures at the center as a measure of multiple variation will tend to overlap.
Step-by-step explanation:
When two data sets have similar variables, at the center as a multiple, the value of the difference measures of of variation explains the visual overlap.
Normally, the higher the value, the less the overlap populations . since it is known that the value is 4 which is small, the population should have an amount that is large of overlap.
Final answer:
When measures of center differ from measures of variation by 4 times, it implies significant differences in data sets, visually showing minimal overlap with separated distributions.
Explanation:
Measures of center and variation: When the measures of center of two data sets differ by 4 times the measure of variation, it indicates a significant difference in the central tendencies of the data sets. The visual overlap of the data sets would be minimal, with the distributions of the two data sets largely separated rather than overlapping.

Suppose you double the radius length of a circle. What happens to the circumference and to the number of radii that will fit around the circle?
If you double the radius of a circle, the circumference also doubles; however, the number of radii that can fit around the circumference remains unchanged.
Explanation:If you double the radius of a circle, the circumference of the circle also doubles because the formula for the circumference of a circle is 2πr (`r` being the radius). Thus if `r` becomes 2r, the circumference becomes 2(2πr) or 4πr, which is twice the original circumference.
Similarly, if you try to fit radii around the circle, you would find that exactly the same number of radii will fit around the circle as before. This is because the radius is the distance from the center of the circle to the circumference, and no matter how long the radius is, you can always fit exactly 2π radii around the circumference. Doubling the radius length therefore does not alter the number of radii that can fit around the circle.

A chest of drawers was originally priced at $100, but Sam waited to buy it until the chest of drawers was on sale for 80% off. If he paid 10% sales tax on the sale price, how much did he pay in total?
Answer:
$25
Step-by-step explanation:
Since it was originally $100, 80% off would mean he would only have to pay $20 for it. But sales tax, you would have to add 10% back of the sale price which was $20. so, 10% of 20 is $5. The sale price, $20, plus the $5 is 25 dollars he had to pay.
After waiting for a 80% off discount, Sam purchased the dresser for $20. Including a 10% sales tax, he paid a total of $22.
Explanation:In this problem, we first need to figure out what 80% off of the original $100 price is. This can be done by converting the 80% discount to a decimal (0.8) and then multiplying it by the original cost ($100). This gives us $80.
However, since this is the amount discounted, we subtract it from the original price to get the sale price of the chest of drawers, so $100 - $80 = $20. This is how much Sam paid before sales tax.
Next, we need to calculate the sales tax amount. We first convert the 10% sales tax to a decimal (0.10), and then we multiply it by the sale price ($20). This gives us $2 in sales tax.
Finally, we add the sales tax to the sale price to get the total amount Sam paid for the chest of drawers: $20 + $2 = $22. So, Sam paid a total of $22 for the chest of drawers.

The diameter, D, of a sphere is 8.4 mm. Calculate the sphere's volume, V.
Use the value 3.14 for a, and round your answer to the nearest tenth
Answer:
73.8 cubic mm.
Step-by-step explanation:
The volume of a square V is given by the formula:
[tex]V= \frac{4}{3}\pi r^{2}[/tex] where r is the radius of the sphere.
We also know that the diameter is two times the radius, so in this case if the diameter is 8.4 mm, then the radius is 4.2 mm.
Now we substitute the information in the formula, taking into account that we are going to use the value of 3.14 for [tex]\pi[/tex].
[tex]V= \frac{4}{3}\pi r^{2}\\ V= \frac{4}{3}(3.14)(4.2)^{2} \\V=\frac{(4)(3.14)(17.64)}{3} \\V=\frac{221.55}{3}=73.8528[/tex]
Which rounded to the nearest tenth is 73.8. Thus, the sphere's volume is 73.8 cubic mm.
Answer:
V = 310.2 mm³
Step-by-step explanation:
The formula for volume of a sphere is given as:
V = 4/3 * π * r³
where r is the radius of the sphere.
We are given the diameter in the question. Diameter is twice the radius. So, radius = diameter/2
radius = 8.4/2
radius = 4.2 mm
V = 4/3 * π * r³
= 4/3 * 3.14 * (4.2)³
V = 310.181
V = 310.2 mm³
Abigail invested $29,000 in an account paying an interest rate of 2.1% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 8 years?
Final answer:
Using the formula for continuous compounding A = Pert, the amount in the account after 8 years will be approximately $34,305 when $29,000 is invested at a 2.1% interest rate, compounded continuously.
Explanation:
Abigail invested $29,000 in an account with an interest rate of 2.1% compounded continuously. To calculate the amount of money that would be in the account after 8 years, we use the formula for continuous compounding: A = Pert, where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), e is the base of the natural logarithm, r is the annual interest rate (as a decimal), and t is the time in years. Plugging in the values: A = 29000e0.021×8.
The calculation results in A ≈ 29000×e0.168≈ 29000×1.18301 = $34305.29. After rounding to the nearest dollar, the amount in the account after 8 years will be $34,305.
Final answer:
To the nearest dollar, there would be approximately $36,884 in Abigail's account after 8 years.
Explanation:
To calculate the future value of an investment with continuous compounding, we can use the formula: A = Pe^(rt), where A is the future value, P is the initial amount, e is a mathematical constant approximately equal to 2.71828, r is the interest rate, and t is the time in years.
For Abigail's investment, P = $29,000, r = 0.021 (2.1% as a decimal), and t = 8 years. Plugging those values into the formula, we get:
A = 29000 * e^(0.021 * 8) ≈ 29,000 * e^0.168 ≈ $36,883.65
Therefore, to the nearest dollar, there would be approximately $36,884 in Abigail's account after 8 years.
Donation Amounts (in dollars) A charity receives donations ranging from 5 to 35 dollars. The donation amounts from 10 different people were used to create the box plot shown above.

Without an actual box plot to reference, it's impossible to accurately determine which set of donation amounts correctly corresponds to the box plot in question.
Explanation:The question seeks to identify the set of donation amounts that matches a given box plot. When analyzing sets of donation amounts to determine which one aligns with a box plot, we look for key features such as the minimum, the maximum, the median, and the quartiles. These features divide the data set into four parts of equal importance, helping us understand the distribution of the data.
Given that there isn't an actual box plot provided, we would typically compare the given options against the features one would expect to find in a box plot:
Minimum and maximum values to set the range.Quartiles that split the data into four equal parts.Median as the middle value when the data is sorted.However, without the specific details of the box plot, such as the exact median or quartile values, we cannot accurately determine which set of donations matches the box plot. Typically, an analysis would involve calculating or identifying these characteristic numbers from each option and then seeing which one fits the description given by the box plot.

A rice store estimates that if it sells each pack of rice forxdollars, then the projected number of packssold daily is 240−10x. What is the price per pack that maximizes its daily profit?
Answer:
Price per pack = 12
Step-by-step explanation:
The profit can be calculated as the product of the price by the quantity sold:
P = x * (240-10x)
P = -10x^2 + 240x
To find the maximum of this quadratic function, we can use the formula to find the vertix:
x_v = -b/2a
Where a and b are coefficients of the quadratic equation (a = -10 and b = 240)
x_v = -240/(-20) = 12
Now, we use this value to find the maximum profit:
P_max = -10*(12)^2 + 240*12 = 1440
