The same brand of jelly beans comes in 2 sizes a 10 ounce bag for $1.99 and an 18 ounce bag for $2.99. Which size is the Better buy per ounce
After calculating the price per ounce for both size bags of jelly beans, the 18-ounce bag at $0.166 per ounce is a better buy per ounce compared to the 10-ounce bag at $0.199 per ounce.
To determine which size of jelly beans is the better buy per ounce, we need to calculate the price per ounce for each bag. Then, we can compare the two to see which one provides a lower cost per ounce, indicating the better value.
Calculate the price per ounce for the 10-ounce bag: $1.99 / 10 ounces = $0.199 per ounce.
Calculate the price per ounce for the 18-ounce bag: $2.99 / 18 ounces = $0.166 per ounce.
Compare the two price per ounce figures: $0.199 per ounce for the 10-ounce bag versus $0.166 per ounce for the 18-ounce bag.
The 18-ounce bag has a lower cost per ounce than the 10-ounce bag, so the 18-ounce bag is the better buy per ounce.
there were 170 people at the concert. If 85% of the seats were filled how many seats are in the auditorium
In order to compute for the number of seats available in the auditorium, you just have to divide the number of people at the concert with the percentage of its utilized capacity.
Solution:
170 people / 85% = 200 seats available in the auditorium
To check the answer:
200 seats x 85% = 170 people are in the concert

If 9 is P percent of 17, then P is a number between
To determine P percent when 9 is a percent of 17, we calculate P ≈ 52.94%. Therefore, P is between 50% and 60%.
To find what P percent is when 9 is a percent of 17, we use the formula for percentage: P = (part/whole) x 100. Here, the part is 9, and the whole is 17. Thus, the calculation will be:
P = (9/17) x 100First, divide 9 by 17, which equals approximately 0.5294. Next, multiply this result by 100 to convert it to a percentage:
P ≈ 0.5294 x 100 = 52.94%So, P is approximately 52.94%. This means that P falls between 50% and 60%.

If p=>q and q=> r, which statement must be true?
The condition 'p implies q' and 'q implies r' logically leads to the conclusion that 'p implies r' due to the transitive property of logical arguments, which forms a valid chain argument called syllogism.
Explanation:Given two conditional statements p⇒q and q⇒r, we can deduce another conditional statement that must logically be true. When p implies q (p⇒q), and q implies r (q⇒r), we can conclude that p⇒r is also true. This is known as the transitive property in logic.
Chain argument or syllogism is a logical argument where a series of premises leads to a conclusion. Using this, when p happens before q, and q precedes r, it follows that p must also lead to r. Therefore, we can construct a logical chain: p⇒q⇒r, resulting in p⇒r.

A probability experiment is conducted wich of these can not be considered a probability of an outcome: 1.015, 0.995, - 0.234, 45%, 2/3, 0.66, 0.45% Can not be considered: 0.995, 45% Can not be considered: 0.995; 0.66 Can not be considered: 1.015, - 0.234 Can not be considered: 0.995; 0.45%; 2/3
In probability, the probability of an outcome is a value between 0 and 1, inclusive. From your list, 1.015 and -0.234 do not fall within this range and thus can't be considered as valid probabilities, whilst 45%, 0.45%, 0.995, 2/3, and 0.66 are valid probabilities.
Explanation:In probability theory, the probability of an outcome is always expressed as a value between 0 and 1, inclusive. In other words, the minimum probability is 0 (representing an event that will not occur) and the maximum is 1 (representing an event that is certain to occur). Probabilities can also be represented as fractions, percentages, or decimal numbers that fall within this range.
Looking at your list, 1.015 and -0.234 cannot be considered valid probabilities, because they fall outside the 0 to 1 range. All percentages should also be converted to decimals before comparison, meaning that 45% is equivalent to 0.45 and is a valid probability, while 0.45% is equivalent to 0.0045 and is also valid. Similarly, 2/3 and 0.66 are valid probabilities because they lie within the 0-1 range.

The diameter was of four half circles are sides of a square with a side length of 7 cm.
Find the exact area of the shaded region in terms of pi. (Please show work)
Answer:
shaded area = 24.5π -49
Step-by-step explanation:
The area of a segment of a circle is given by the formula ...
A = 1/2r²(θ -sin(θ))
Here, the radius of the circle is (7 cm)/2 = 3.5 cm, and the angle of interest is π/2 radians.
There are 8 segments of this size in the shaded area, so we have ...
shaded area = 8(1/2)(3.5 cm)²(π/2 -sin(π/2))
shaded area = 24.5π -49

State the geometric sequence both recursive and explicit formulas.
Answer:
recursive formula = [tex]a_{n} = a_{n-1}* r[/tex]
explicit formula: [tex]a_{n} = a_{1}*r^{n-1}[/tex]
Step-by-step explanation:
Thinking process:
Let a sequence be given as:
3 9 27 81
As can be observed from the sequence, the next number of the sequence is a multiple of 3, that is 9 is a multiple of 3. Similarly, 27 is 9 multiplied by 3
then, let the first term be a. the common multiplying factor will be r (in this case 3). Then the formula will be [tex]a_{n} = a_{n-1}*r[/tex]
In addition, the powers rule applies.
For instance:
9 = [tex]3^{2}[/tex]
27 = [tex]3^{3}[/tex]
81 = [tex]3^{4}[/tex]
Then the explicit formula will be [tex]a_{n} = a_{1}*r^{n-1}[/tex]

The Running Shoe Company advertised that tbe would award a number of prizes equal to 1% of the total number of entries in a contest .They received 1,600 entries .How many prizes should they award?
The Running Shoe Company should award 16 prizes, as 1% of 1,600 entries is 16.
The student asked, "How many prizes should The Running Shoe Company award if they received 1,600 entries in a contest and they award a number of prizes equal to 1% of the total number of entries?"
To find the number of prizes, we need to calculate 1% of 1,600 entries.
Step 1: Convert the percentage to a decimal by dividing by 100. So, 1% becomes 0.01.
Step 2: Multiply the total number of entries by 0.01 to find 1% of it.
1,600 entries * 0.01 = 16 prizes
Therefore, The Running Shoe Company should award 16 prizes.

The measurement of angle A in the given cyclic quadrilaterals, is 135°
What is a cyclic quadrilateral?A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. It is also sometimes called inscribed quadrilateral.
Given that, a quadrilateral ABCD is inscribed in a circle, so this type of quadrilaterals are called cyclic quadrilaterals, m ∠ A = 3x+6 and m ∠ C = x+2
We need to find, m ∠ A,
We know that in cyclic quadrilaterals, the opposite angles are supplementary,
Therefore,
m ∠ A + m ∠ C = 180°
3x+6+x+2 = 180°
4x+8 = 180°
4x = 172°
x = 43°
Therefore,
m ∠ A = 3x+6
m ∠ A = 3(43)+6
m ∠ A = 135°
Hence, the measurement of angle A in the given cyclic quadrilaterals, is 135°
