What is the probability of a die landing on an even number on the first toss, and then an odd number on the second toss?
Dice- 6 sides
Please help
Answer:
i dotn know sorry
Step-by-step explanation:
and this is why brainly is bad
Answer:
1/4 chance
Step-by-step explanation:
Number of even numbers on a die-3
Number of odd numbers on a die-3
a die has 6 sides,
therefore
1/2 of the numbers on a die are even and 1/2 are odd
so a 3/6 chance (1/2 chance (simplify)) of landing on an even number on the first roll
And a 3/6 chance (1/2 chance (simplify)) of landing on an odd number on the second roll
Multiply the two together and a 9/36 chance of this event or simplified to a 1/4 chance of this event
Describe the translation that maps ABCD onto A’B’C’D’
A. Left 6, up 5
B. Left 6 down 5
C. Right 6, up 5
D. Right 6, down 5
Pls don’t do this just for the points.
Answer:
D
Step-by-step explanation:
The translation that maps ABCD onto A’B’C’D’ is Right 6, down 5.
What is the translation of coordinates?Translation on the coordinate plane is sliding a point or figure in any direction without any changes in size or shape.
In fact, during translation, the coordinates of the vertices of a figure or point change, and they slide left or right, up, or down without changing size or shape.
The translation that maps ABCD onto A’B’C’D’ is;
Shift ABCD to the right side by 6 units then shifted down by 5 units to get A'B'C'D'.
ABCD moved ( 6 units ) times to the ( right), and ( 5 units ) times to the ( bottom) to convert into A'B'C'D'.
Hence, the translation that maps ABCD onto A’B’C’D’ is Right 6, down 5.

Answer:
Circumference = 3.14 diameter C = 3.14(6) Answer: 18.84
Step-by-step explanation:
The equation for circle at A is (x+4)²+(y+2)²=9 whose radius is 3 units.
The equation of the circle is (x-h)²+(y-k)²=r²
Where h and k are the coordinates of centre of circle and r is radius of the circle.
From the given figure (h, k) is (-4, -2) and r is 3 units
Plug in these values in the equation of circle.
(x-(-4))²+(y-(-2))²=3²

You raise $420 during a fundraising event. The amount of money that you raise is 120% of your goal. How much more did you raise than your goal?
9514 1404 393
Answer:
$70
Step-by-step explanation:
The excess amount is 20% of the goal. The given amount is 120% of the goal, so the proportion of the given amount that is excess is ...
(20% of goal)/(120% of goal) = 1/6
Then the excess is (1/6)($420) = $70.
You raised $70 more than the $350 goal.
The original fundraising goal was $350, and since $420 was raised, which is 120% of the goal, $70 more was raised than the goal.
Explanation:To find out how much more was raised than the goal during the fundraising event, start by understanding the percentage given. The $420 raised is 120% of the goal, which means the goal amount represents 100%. To calculate the original goal, you should divide the amount raised by the percentage raised (expressed as a decimal), so you divide 420 by 1.2 (since 120% as a decimal is 1.2).
Now, calculate the goal amount:
420 / 1.2 = $350
Therefore, the original goal was $350. Since the amount raised was $420, we subtract the goal from the amount raised to determine how much more was raised:
420 - 350 = $70.
Thus, the amount raised exceeded the goal by $70.

Andre says 10x + 6 and 5x + 11 are equivalent because they both equal 16 when x is 1. Do you agree with Andre?
Answer:
No, They are not equivalent
Step-by-step explanation:
The two expressions are only said to be equivalent if they are the same regardless of whatever value the variable(s) is.
The variable in this question is x.
To prove this, we equate both expressions:
[tex]10x + 6 = 5x + 11[/tex]
[tex]10x - 5x = 11 - 6\\\\\\5x = 5\\\\\\x = 1[/tex]
This shows that they have the same value ONLY when x is 1.
This is why Andre says that they are equivalent, but they are not.
No, I do not agree with Andre because the two equations 10x + 6 and 5x + 11 are indeed equivalent.
Explanation:No, I do not agree with Andre. Two equations are considered equivalent if they have the same solution for all values of x.
Let's check if 10x + 6 and 5x + 11 are equivalent by substituting x = 1 into both equations:
For 10x + 6: 10(1) + 6 = 10 + 6 = 16
For 5x + 11: 5(1) + 11 = 5 + 11 = 16
We can see that both equations indeed equal 16 when x is 1, so Andre is correct in this case. 10x + 6 and 5x + 11 are equivalent equations.

Find the common difference: 1, 201, 401, 601, ... A
The common difference of the arithmetic sequence 1, 201, 401, 601, ... is 200, which is the difference between successive pairs of terms.
Explanation:In Mathematics, the common difference in an arithmetic sequence is the amount by which successive terms increase. In the given series: 1, 201, 401, 601, ..., the common difference can be found by subtracting a term from the term after it. For instance, if we subtract 1 (the first term) from 201 (the second term), we get 200. If we do the same for 201 and 401 (the second and third terms), we also get 200. This means that the common difference for this arithmetic sequence is 200.

Answer:
x-6
Step-by-step explanation:
The formula for the area of a rectangle is (l)(w)
x-5(w)=x²-11x+30
To solve, you need to put the quadratic equation into standard form
x-5(w)=(x-5)(x-6)
Divide both sides of the equation by x-5 to isolate the width(basically strike out x-5 on both sides)
the width is x-6
I pretty sure that's the right answer since (x-5)(x-6)=x²-11x+30, but I'm in geometry right now, and I had to go back and re-learn.

Answer:
1. C.
2. B.
3. A.
Step-by-step explanation:
First situation given:
An adult and 5 children rent skates. It costs $ 4 per adult for skates and a total of $ 16.
Correct equation: C
4 + 5 x = 16
Second situation given:
It costs Mikael $ 4 to make a bike bag, and he sells each for $ 5. He has made a profit of $ 16, so far.
Correct equation: B
( 5 − 4 ) x = 16
Third situation given:
It was 16°C. It began falling 4°C per hour until it reached 5°C.
Correct equation: A
16 − 4 x = 5
Equations are matched to situations based on the context provided: the adult and children renting skates is described by 4 + 5x = 16, Mikael's profit from selling bike bags fits the equation (5 - 4)x = 16, and the temperature dropping over time corresponds to 16 - 4x = 5.
To match each equation to its corresponding situation, let us consider each situation and then associate the relevant equation.
Adult and children renting skates: An adult rents skates at $4, and the total cost including 5 children is $16. The equation representing the total cost is the adult's cost plus 5 times the children's cost equals $16, which is: 4 + 5x = 16.
Mikael making a profit from bike bags: Mikael spends $4 to make a bike bag, sells it for $5, and has made a profit of $16. To determine how many bags he sold (x), we can use the equation that accounts for profit, which is the selling price minus the cost of making the bag, multiplied by the number of bags, equals the profit: (5 - 4)x = 16.
Temperature drop: The temperature started at 16°C and dropped at a rate of 4°C per hour until it reached 5°C. To find the number of hours (x) it took for the temperature to drop, we can use the equation that links the initial temperature, minus the drop per hour times the number of hours, equals the final temperature: 16 - 4x = 5.
Now, we can clearly match the equations to their situations:
The situation where an adult and children rent skates corresponds to the equation 4 + 5x = 16.
Mikael making a profit from selling bike bags is represented by the equation (5 - 4)x = 16.
The decrease in temperature over time until it reached 5°C is described by the equation 16 - 4x = 5.
The probability of rolling a 6 on a biased die is 1/5
Work out the probability of rolling exactly one 6
Answer:
if the probability of a 6 is 1/5, the probability of “not six” is 4/5. The probability of a 6 on the first roll and not on the second is 1/5 x 4/5 = 4/25. The six could come on the second roll so that probability must be doubled. The overall probability of exactly one six is 8/25 or 0.32.
Step-by-step explanation:
James’s four-year-old brother is trying to arrange black and yellow Legos in rows. He has 56 yellow Legos and 120 black Legos. He wants to arrange them in rows so that there are either only yellow or only black Legos in each row, and so that each row has the same number of Legos. What is the least number of rows he can make?
Answer:
22
Step-by-step explanation:
The four-year-old brother can arrange the Legos in rows of 8.
Explanation:To find the least number of rows the four-year-old brother can make with the black and yellow Legos, we need to determine the greatest common divisor (GCD) of 56 and 120. The GCD will represent the number of Legos in each row.
To find the GCD, we can use the Euclidean algorithm. Divide the larger number (120) by the smaller number (56). The remainder is 8. Then, divide the smaller number (56) by the remainder (8). The new remainder is 0.
Therefore, the GCD of 56 and 120 is 8. This means that the four-year-old brother can arrange the Legos in rows of 8, with 7 rows of black Legos and 1 row of yellow Legos, or vice versa.
