A six-sided die with sides numbered 1 through 6 is tossed 2 times. What is the probability that the product of the two toss results will be even?
Answers
The probability of the product being even when two six-sided dice are rolled is 3/4 or 0.75, since there is a 1/2 chance of rolling an even number on each die, and the only way to have an odd product is if both dice show odd numbers.
Explanation:To solve this problem, we will find the probability that the product of two rolls of a six-sided die is even. The product of two numbers is even if at least one of the numbers is even. In the case of a six-sided die, there are 3 even sides (2, 4, 6) and 3 odd sides (1, 3, 5).
For the first roll, the probability of rolling an even number is 3 out of 6, or 1/2. The second roll is independent of the first, so the probability of rolling an even number again is also 1/2. To find the probability that at least one roll is even, we can use the complement rule which states that the probability of an event 'E' is 1 minus the probability of the event's complement. The only way not to get an even product is to roll two odd numbers.
The probability of rolling an odd number on the first toss is 3/6, and similarly 3/6 for the second toss. Therefore, the probability of both being odd is (3/6) × (3/6) which simplifies to 1/4. Hence, the probability of at least one die being even (and therefore the product being even) is 1 - 1/4 = 3/4.
The final answer is that the probability of getting an even product from two rolls of a six-sided die is 3/4 or 0.75.

Question 1.
Okay let's go through each option and see if it could be there or not.
Quadrant IV?
It could not be in quadrant IV because in quadrant IV all of the y values are negative, and all of the x values are positive.
y-axis?
It could not be on the y-axis because on the y-axis all of the x values are 0, and it already said the point is not (0, 0).
Quadrant II?
It could not be in Quadrant II because in quadrant II all of the y values are positive and all of the x values are negative.
Quadrant III?
It could be in Quadrant III because in quadrant III all of the y values are negative and all of the x values are negative.
Quadrant I?
It could be in Quadrant I because in quadrant I all of the y values are positive and all of the x values are positive.
x-axis?
It could not be on the x-axis because on the x-axis all of the y values are 0, and it already said the point is not (0, 0).
So the answer to question 1. is Quadrant I and Quadrant III.

B) You should take all integers from (-2, 2) which are: -2, -1, 0, 1, 2 and put them one by one in the example:
x = -2
y1 = 4^-(-2) = 4^2 = 16
y2 = 2^(-(-2) + 1) = 2^(2+1) = 2^3 = 8
y1 ≠ y2 => so x=-2 isn't our answer
-------------------------------------------------------
x = -1
y1 = 4^-(-1) = 4^1 = 4
y2 = 2^(-(-1) + 1) = 2^(1+1) = 2^2 = 4
y1 = y2 => so our answer will be x = -1
-------------------------------------------------------
x = 0
y1 = 4^-(0) = 4^0 = 1
y2 = 2^(-(0) + 1) = 2^(0+1) = 2^1 = 2
y1 ≠ y2 => so x=0 isn't our answer
--------------------------------------------------------------
x = 1
y1 = 4^-(1) = 4^(-1) = 1/4
y2 = 2^(-(1) + 1) = 2^(-1+1) = 2^0 = 1
y1 ≠ y2 => so x=1 isn't our answer
--------------------------------------------------------------
x = 2
y1 = 4^-(2) = 4^(-2) = 1/16
y2 = 2^(-(2) + 1) = 2^(-2+1) = 2^(-1) = 1/2
y1 ≠ y2 => so x=2 isn't our answer
Which means that our final answer is: x=-1
C) You should draw both graphics, and their intersection point (x) will be the answer.

Of the children at Molly's daycare, 1/8 are boys and 2/5 of the boys are under 1 year old. How many boys at the daycare are under 1 year old.
Answers
To find the number of boys at Molly's daycare that are under 1 year old, we can use the given fractions to calculate the answer.
Explanation:To find the number of boys at Molly's daycare that are under 1 year old, we first need to determine the total number of boys at the daycare. Since 1/8 of the children are boys, we can assume that 1/8 of the total number of children are boys. Let's say there are a total of x children at the daycare. If 1/8 of x represents the number of boys, we can write the equation (1/8) * x = number of boys. Now, we need to find the number of boys that are under 1 year old. Since 2/5 of the boys are under 1 year old, we can write the equation (2/5) * (1/8) * x = number of boys under 1 year old. Simplifying this equation gives us the answer: (1/20) * x = number of boys under 1 year old.
Fathi wants to print out a PDF document that is 48 pages long. To save paper, he decides to print on both sides of each sheet and to print two pages on each side of the sheet.
Answers
Fathi will need 12 sheets of paper to print a 48 page PDF document by printing two pages on each side of the paper. The total page count is halved twice, once for each side of a sheet and again for each pages printed per side.
Explanation:Fathi has a PDF document that is 48 pages long and he wants to print it in a way that saves paper. This involves printing two pages on each side of a sheet of paper and then using both sides of the sheet. To find out how many sheets he will need, we can start by halving the total page count because printing two pages on each side means we effectively halve the number of pages. So, 48÷2 equals 24 'effective' pages. Then, because he's printing on both sides of each sheet, we halve that number again, giving us 24÷2 equal 12 sheets of paper. So Fathi will need 12 sheets of paper to print his 48-page document.

Figure X Is translated down 5 and then reflected over the y-axis, forming figure Y
Answers
hope this helps:)
Answer:
Option D.
Step-by-step explanation:
In the graph attached if we consider a point X. We find that the given point or figure is reflected over the y - axis first.
It means x gets a mirror image in second quadrant when reflected over y-axis (equidistant form y-axis) and the coordinates of X' becomes(-3, 2).
Now this point X'(-3, 2) is translated down by 5 units to form a new point Y in third quadrant with the new coordinates (-3, -3)
Y- coordinates of Y = Y coordinates of X' - (-3)
= 2 - (-3) = 5 units down.
Therefore, Option D.is the correct option.
What is the length of the segment of the number line consisting of the points that satisfy (x-4)^2 <= 9$?
Answers
first we find that 4 times 4 is 16 then we subtract 16 from 9 which results in 5.
now lets try the question (5-4)^2=9 the square roots of 5 and 4 are 25 and 16
25-16 is 9 so the length should be 5
The length of the number line segment satisfying the inequality (x-4)² ≤ 9 is 6 units, found by solving the inequality to get the range 1 <= x <= 7 and subtracting the lower endpoint from the higher endpoint.
To find the length of the segment of the number line for the points that satisfy the inequality (x-4)² ≤ 9, we first solve the inequality. Taking square roots of both sides gives us |x-4| ≤ 3.
This means that the distance from x to 4 on the number line is less than or equal to 3. We can express this as two separate inequalities: x-4 ≤ 3 and x-4 ≥ -3. Solving these gives us x ≤ 7 and x ≥ 1, which represent the endpoints of the segment on the number line.
The length of this segment is the difference between the endpoints, which is 7 - 1 = 6. So, the length of the number line segment that contains all points satisfying the original inequality is 6 units.

show the graphical representation of 2/3 using a pie chart.
Answers
To produce a pie chart reflecting 2/3, the pie must be divided into 3 equal parts, representing the whole. Two of these sections are then filled in or marked, representing the 2 in the fraction 2/3 or roughly 66.7% of the total pie chart.
Explanation:To create a pie chart representation of the fraction 2/3, you need to think of the pie as representing the whole or 1. From there, we split the pie into 3 equal parts (since your denominator is 3), then, you will shade in 2 of those parts (as your numerator is 2). That shaded area of the pie chart represents 2/3.
It's essential to remember that each slice of the pie in a pie graph represents a share of the total or percentage. Thus, if you consider your pie to be 100%, then each one-third piece would be roughly 33.3%, and two of these would give you approximately 66.7%, which is the decimal equivalent of 2/3.

54=2*3*3*3
2 and 3 cannot be further factored so that is the prime factorization.
Final answer: 2*3*3*3
Final answer:
The prime factorization of 57 is 3 × 19, and the prime factorization of 54 is 2 × 3 × 3 × 3.
Explanation:
The prime factorization of 57 is 3 × 19. To find the prime factorization of 57, we start by dividing the number by the smallest prime number, which is 2. We continue dividing until we cannot divide any further. In this case, 57 is not divisible by 2. Next, we try dividing by the next smallest prime number, which is 3. 57 divided by 3 equals 19, which is a prime number. Therefore, the prime factorization of 57 is 3 × 19.
The prime factorization of 54 is 2 × 3 × 3 × 3. To find the prime factorization of 54, we use the same process. We start by dividing the number by 2, then 3, and so on, until we cannot divide any further. 54 divided by 2 equals 27. 27 divided by 3 equals 9, and 9 divided by 3 equals 3. 3 is a prime number, so we stop here. Therefore, the prime factorization of 54 is 2 × 3 × 3 × 3.
