Which of the following sets of numbers could be the lengths of the sides of a triangle? A. 3 ft, 6 ft, 9 ft B. 3 ft, 5 ft, 7 ft C. 3 ft, 6 ft, 12 ft D. 3 ft, 9 ft, 27 ft
Answers
B. 3 ft, 5 ft and 7 ft
Explanation:
In any triangle, the sum of any two sides must be greater that the third one.
Therefore, to know if the given sides represent a triangle or not, all what we will do is add the two short sides and compare the result to the largest one.
We would have 3 options:
sum of short sides > longest side ......> It is a triangle
sum of short sides < longest side ......> It is not a triangle
sum of short sides = longest sides ....> It is not a triangle
Now, for the given:
1- Option A:
sum of short sides = 3 + 6 = 9 ft which is equal to the longest side
This option is incorrect
2- Option B:
sum of short sides = 3 + 5 = 8 ft which is greater than the longest side
This option is correct
3- Option C:
sum of short sides = 3 + 6 = 9 ft which is less than the longest side
This option is incorrect
4- Option D:
sum of short sides = 3 + 9 = 12 ft which is less than the longest side
This option is incorrect
Based on the above, the only correct option is B.
Hope this helps :)

Kiesha’s quality-control manager told her she must have 97% of her clocks functioning properly. She found a report that said 6 out of 300 clocks tested were not working properly. Kiesha predicts that she will have enough working clocks to please the manager. Which statements are true about Kiesha’s prediction? Check all that apply.
Kiesha’s experimental probability is 1/30
Kiesha will have more than 97% of the products working.
Kiesha will not meet 97% because more than 3% of her clocks will be broken.
Kiesha’s experimental probability is 1/50
When the inventory is 4000 clocks, the prediction is that 3920 clocks will work.
Answers
Kiesha will have more than 97% of the products working. The experimental probability is 0.98, not 1/30 or 1/50. When the inventory is 4000 clocks, the prediction is that 3880 clocks will work.
Explanation:To determine if Kiesha will have enough working clocks to please the manager, we need to calculate the percentage of clocks that are functioning properly. We know that 6 out of 300 clocks tested were not working, which means 300 - 6 = 294 clocks were working properly. The percentage of working clocks is (294/300) x 100% = 98%. This means that Kiesha will have more than 97% of the products working, so the statement 'Kiesha will have more than 97% of the products working' is true. The statement 'Kiesha’s experimental probability is 1/30' is false because the experimental probability is calculated by dividing the number of successful outcomes (294) by the total number of trials (300), giving 294/300 = 0.98. The statement 'Kiesha will not meet 97% because more than 3% of her clocks will be broken' is false because the percentage of working clocks is 98%. The statement 'Kiesha’s experimental probability is 1/50' is false because the experimental probability is 0.98, not 1/50. When the inventory is 4000 clocks, the prediction is that 97% of the clocks will work, which is (0.97 x 4000) = 3880 clocks.
Kiesha's experimental probability of a clock not working is 1/50, and with 98% of her clocks working properly, she will exceed her manager's 97% requirement. When scaled to an inventory of 4000 clocks, Kiesha can expect 3920 to be functioning correctly.
Explanation:When analyzing Kiesha's prediction about her clocks, we find that if 6 out of 300 clocks are not functioning, then 294 clocks are working properly. To determine if Kiesha will have enough working clocks to please her manager (who requires 97% to be in working order), we calculate the percentage of working clocks:
294/300 = 0.98 or 98%
This is higher than the manager's requirement of 97%. Therefore, the following statements about Kiesha's prediction are true:
Kiesha's experimental probability of a clock not working is 6/300, which reduces to 1/50, not 1/30.Kiesha will have more than 97% of the products working, as 98% are functioning properly.If Kiesha has an inventory of 4000 clocks and the same proportion of nonfunctioning clocks, she would expect 3920 clocks to work, because 98% of 4000 is 3920.Thus Kiesha's prediction that she will meet the quality requirements is accurate.

A math club took a math test. Twelve of the members had an average score of 80. Eighteen of the members had an average score of 86. what is was the class average
Answers
18 x 86 = 1548
960 + 1548 = 2508
12 + 18 = 30
2508/30 = 83.6
The class average is 83.6
There were twelve people who had an average of 80. With this, you just have to believe they all received an 80%. The same with the score of 86.
12•80=960
18•86=1,548
Now add them together.
960+1,548=2,508
Now add the total students.
12+18=30
2,508/30
83.6
The class average is 83.6%

a storage container is shaped like a rectangular prism the volume of the container is 1360 cubic feet the area of the base of the container is 160 square feet what is the height of the container
Answers
The volume of a prism is given by:
Volume of a prism = base area * height
From the the problem, we have been given volume of the prism = 1360 feet^3
Base area = 160 feet^2
height = x
1360 =160 * x
x = 1360/160 = 8.5 feet
Height of the container = 8.5 feet
Find the volume of a right prism with height h=10 cm, if the base is a trapezoid with height htr = 3 cm and bases of 2 cm and 5cm
Answers
Volume =10.5 x 10 = 105 cm³
Answer: 105 cm³
We have been given that the base of the prism is a trapezoid. Hence, first of all we find the area of the trapezoid.
Trapezoid has height 3 cm and bases of 2 cm and 5 cm.
Hence, the area of the trapezoid is given by
[tex]A=\frac{a+b}{2} \times h\\ \\ A=\frac{2+5}{2} \times 3\\ \\ A=\frac{21}{2}[/tex]
Therefore, the volume of the right prism with height h=10 cm is given by
[tex]V=\text{Base area }\times { height}\\ \\ V=\frac{21}{2} \times 10\\ \\ V=105 cm^3[/tex]
Therefore, the volume of the right prism is 105 cubic centimeters.

Richard and samantha are charting their monthly cash flow. They have some expenses like car repairs and vacations that are not paid each month. How can they account for these non-monthly expenses ?
Answers
This way they can take vacations or if they have car troubles
It would make their life so much easier
Final answer:
Richard and Samantha should estimate yearly costs for non-monthly expenses, divide by 12, and save this amount each month, incorporating it as a fixed expense in their budget.
Explanation:
Richard and Samantha can account for non-monthly expenses in their monthly cash flow by setting aside money each month for these irregular expenses. To do this, they should estimate the total cost of these expenses for the year and divide that amount by 12. This will provide the monthly amount they need to save in order to cover costs such as car repairs and vacations without disrupting their budget. Each month, this amount should be treated like a fixed expense and set aside in a savings or separate account, ensuring that funds are available when these expenses occur.
Example:
Car Repairs: Estimated at $600 per year (divide by 12 = $50 per month)
Vacations: Estimated at $1200 per year (divide by 12 = $100 per month)
By including these estimated expenses in their monthly budget, they can create a more accurate and effective budget that accommodates all their financial activities throughout the year.

The probability of Jaden making a free throw is 15%. Predict the number of free throws that he can expect to make if he attempts 40 free throws.
Answers
We have been given that the probability of Jaden making a free throw is 15%.
Now, we have to predict the number of free throws that he can expect to make if he attempts 40 free throws.
In order to find the total number of free throws, we will find 15% of 40.
Therefore, the number of free throws should be
[tex]15\% \text{ of }40\\ \\ =\frac{15\times 40}{100} \\ \\ =\frac{600}{100} \\ \\ =6[/tex]
Therefore, the number of free throws that he can expect to make if he attempts 40 free throws is 6.
