3/6 should b you answer answer
Final answer:
The volume will be of 6.3 for the second model.
Explanation:
The student is asked to calculate the volume of the second model pyramid, Khafre's pyramid, which is 9/10 the volume of the first model, Khufu's pyramid. The student has already calculated that, for Khufu's pyramid, S = √3*73.5/4.5=7. To find the volume Kristina should make the second model, we simply multiply the volume of the first model by 9/10.
Although the question does not provide the exact volume of the first model, we will assume the value of S given is the volume of Khufu's pyramid model. Therefore, the volume of Khafre's pyramid model should be 7 * (9/10) = 6.3.
This result is based on the proportion given between the two pyramids' volumes and is a straightforward calculation of this proportion.

When, reflection takes place,the two, Image, and Pre-Image are Congruent, that is neither the shape nor the Size changes only translation of the shape takes place on the coordinate plane.
Option C: → Reflection across y = x.
Answer:
C. reflection across y = xStep-by-step explanation:
The given transfomation is
[tex]A(-1,3) \implies A'(3,-1)\\B(2,4) \implies B'(4,2)\\C(-5,6) \implies C'(6,-5)[/tex]
Notice that the rule of the given transformation is
[tex](x,y) \implies (y,x)[/tex]
That is, the coordinates were change of position, like an inverse.
According to transformation rules, this represents a reflection across the line [tex]y=x[/tex].
Therefore, the right answer is C.

A number cube has sides numbered 1 through 6. The probability of rolling a 2 is 16 .
What is the probability of not rolling a 2?
Enter your answer as a fraction, in simplest form, in the box.
Answer: The probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]
Step-by-step explanation: Given that a number cube has sides numbered 1 through 6. And the probability of rolling a 2 is [tex]\dfrac{1}{6}.[/tex]
We are to find the probability of not rolling a 2.
Let, 'A' denotes the event of rolling a 2.
So, we have
[tex]P(A)=\dfrac{1}{6}.[/tex]
The event of not rolling a 2 is given by the complement of event A.
The probability of the complement of event 'A' can be calculated as
[tex]P(A')=1-P(A)=1-\dfrac{1}{6}=\dfrac{5}{6}.[/tex]
Thus, the probability of not rolling a 2 is [tex]\dfrac{5}{6}.[/tex]
The line plots show the number of hours two groups of kids spent studying last weekend.
How does the data compare for the two groups of kids?
The 10- to 13-year olds spent an average of 6 hours studying last weekend.
The range for the hours spent studying last weekend for the 10- to 13-year olds is the same as the range for the hours spent studying last weekend for the 14- to 17-year olds.
The median value for the hours spent studying last weekend for the 10- to 13-year olds is greater than the median value for the hours spent studying last weekend for the 14- to 17-year olds.
The 14- to 17-year olds spent more hours studying, on average, last weekend than the 10- to 13-year olds.
We can conclude that: the 14- to 17-year olds spent more hours (6.8 hours) studying, on average, last weekend than the 10- to 13-year olds (4.3 hours).
What is Range, Median, and Average of a Data Distribution:Range = max - minMedian = middle valueAverage = total sum of values/number of values.Range for hours spent studying for 10 - 13 year olds = 8 - 1 = 7
Range for hours spent studying for 14 - 17 year olds = 10 - 4 = 6
Median for hours spent studying for 10 - 13 year olds = 4
Median for hours spent studying for 14 - 17 year olds = 7
Average for hours spent studying for 10 - 13 year olds = (1+1+2+4+4+4+4+6+6+7+8)/11 = 4.3
Average for hours spent studying for 14 - 17 year olds = (4+4+4+4+6+7+8+9+9+10+10)/11 = 6.8
Therefore, we can conclude that: the 14- to 17-year olds spent more hours (6.8 hours) studying, on average, last weekend than the 10- to 13-year olds (4.3 hours).

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.

Write an equation that you can use to solve for x. Enter your answer in the box. Two lines intersect at a point, forming two adjacent angles. One adjacent angle is labeled x degrees and the other adjacent angle is labeled 47 degrees.
Answer: The value of x is 133°.
Step-by-step explanation:
Since we have given that
Two lines intersect at a point forming two adjacent angles.
Measure of one adjacent angle is labeled as = x degrees
Measure of other adjacent angle is labeled as = 47 °
We need to find the value of x in degrees.
As shown in the figure:
Since they are adjacent angles.
So, we can write it as
[tex]x+47^\circ=180^\circ\\\\x=180^\circ-47^\circ\\\\x=133^\circ[/tex]
Hence, the value of x is 133°.
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.

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%.

a number multiplied by -8, subtracted from the sum of 14 and five times the number
Let us suppose the number is x. Now we try to make an algebraic expression going step by step.
Step 1:
Five times the number means 5 multiplied by x.
So it becomes 5x.
Step 2:
Sum of 14 and five times the number means 5x+14.
Step 3:
Number multiplied by -8 means -8x.
Step 4:
Subtract the expression in step (3) from expression in step (2)
5x+14-(-8x)
Now we can simplify it further,
5x+14+8x
Combining like terms,
13x+14
Answer: The final expression becomes 13x+14.
