Which number rounds to 10,000 when you round it to the nearest ten thousand and to 6,000 when you round it to the nearest thousand?
Answers
Answer:
10000
Step-by-step explanation:
The answer would be 10000. You always use the digit to the right of the place you want to round to help you determine whether to round up or down. But notice you said "round the thousand", but you are actually rounding the ten thousand, by looking at the thousand.
Answer:
The number that rounds to 10,000 when rounded to the nearest ten thousand and to 6,000 when rounded to the nearest thousand is 7,500.
When 7,500 is rounded to the nearest ten thousand, the result is 10,000 because the ten thousand digit is 1 and the rounding digit (the thousands digit) is 5, which is greater than or equal to 5.
When 7,500 is rounded to the nearest thousand, the result is 6,000 because the rounding digit (the hundreds digit) is 5, which rounds up the tens digit to 0 and changes the thousands digit to 6.

Answers
The elements of the complement of set K (K') are {1, 4, 6, 8, 9}.
The elements of the complement of set K (K'), we need to determine all the elements in the universal set that are not in set K.
The universal set, denoted as U, is defined as the set of positive integers less than 10.
The elements in the universal set U are {1, 2, 3, 4, 5, 6, 7, 8, 9}.
Set K is defined as the set of prime numbers.
The prime numbers less than 10 are {2, 3, 5, 7}.
To find the complement of set K (K'), we need to identify all the elements in the universal set U that are not in set K.
K' = U - K
Substituting the values, we have:
K' = {1, 2, 3, 4, 5, 6, 7, 8, 9} - {2, 3, 5, 7}
Performing the set difference operation, we remove the elements in set K from the universal set U:
K' = {1, 4, 6, 8, 9}
These are the positive integers less than 10 that are not prime numbers.

Barney has a biased coin. When the coin is thrown once, the probability that the coin will land heads is 0.3 Barney throws the coin 4 times. Work out the probability that the coin will land heads exactly 3 times. (3 marks)
Answers
The probability that the coin will land heads exactly three times in four throws is approximately 0.0756 or 7.56%. We can use the binomial probability formula, which is P(X=k) = (n choose k) * p^k * (1-p)^(n-k), where X is the number of successes, n is the total number of trials, k is the number of successes we're interested in, p is the probability of success on a single trial, and (n choose k) is the binomial coefficient.
In this case, n=4, k=3, and p=0.3. So the probability of getting exactly three heads is: P(X=3) = (4 choose 3) * 0.3^3 * (1-0.3)^(4-3)
= 4 * 0.027 * 0.7
= 0.0756
Therefore, the probability that the coin will land heads exactly three times is 0.0756.
To calculate the probability of the coin landing heads exactly three times out of four throws, we will use the binomial probability formula. The formula is: P(X=k) = (nCk) * (p^k) * (q^(n-k))
In this case, n=4 (number of throws), k=3 (number of heads), p=0.3 (probability of heads), and q=0.7 (probability of tails, which is 1-p). Using the formula, the answer to the probability of the coin landing heads exactly three times in four throws is: P(X=3) = (4C3) * (0.3^3) * (0.7^(4-3))
P(X=3) = 4 * (0.027) * (0.7)
P(X=3) ≈ 0.0756

given the equation 4x^2 − 8x + 20 = 0, what are the values of h and k when the equation is written in vertex form a(x − h)^2 + k = 0? a. h = 4, k = −16 b. h = 4, k = −1 c. h = 1, k = −24 d. h = 1, k = 16
Answers
the values of h and k when the equation is written in vertex form a(x − h)^2 + k = 0 is (d) h = 1, k = 16.
To write the given quadratic equation \(4x^2 - 8x + 20 = 0\) in vertex form, \(a(x - h)^2 + k = 0\), we need to complete the square. The vertex form allows us to easily identify the vertex of the quadratic function.
First, let's factor out the common factor of 4 from the equation:
\(4(x^2 - 2x) + 20 = 0\)
Next, we want to complete the square for the expression inside the parentheses, x^2 - 2x. To do this, we take half of the coefficient of x (-2), square it, and add it inside the parentheses. However, since we added an extra term inside the parentheses, we need to subtract it outside the parentheses to maintain the equality:
\(4(x^2 - 2x + (-2/2)^2) - 4(1)^2 + 20 = 0\)
Simplifying further:
\(4(x^2 - 2x + 1) - 4 + 20 = 0\)
\(4(x - 1)^2 + 16 = 0\)
Comparing this to the vertex form, \(a(x - h)^2 + k\), we can identify the values of h and k. The vertex form tells us that the vertex of the parabola is at the point (h, k).
From the equation, we can see that h = 1 and k = 16.
Therefore, the correct answer is (d) h = 1, k = 16.

Two factor plants are making tv panels. Yesterday, plant A produced 8000 panels. Ten percent of the panels from plant A and 3% of the panels from plant B were defective. How many panels did plant B produce, if the overall percentage of defective panels from two plants was 7%?
Answers
Let panels produced by plant A be represented by a

Can someone help me with this Question.

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.
\(P=3W+D\)A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.
B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.
\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.
That leaves \(27-14=13\) matches. These represent the matches team lost.
Finally, the answers are below.
\(A)29\)
\(B)13\)
Answer:
a) 29 points
b) 13 losses
Step-by-step explanation:
You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.
A 8 wins, 5 drawsThe number of points the team has is ...
P = 3W +D
P = 3(8) +(5) = 29
The team has 29 points.
B 54 pointsYou want the number of losses the team has if it has 54 points and 12 draws after 39 games.
The number of wins is given by ...
P = 3W +D
54 = 3W +12
42 = 3W
14 = W
Then the number of losses is ...
W +D +L = 39
14 +12 +L = 39 . . . substitute the known values
L = 13 . . . . . . . . . . subtract 26 from both sides
The team lost 13 games.
__
Additional comment
In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Find the slope of the line that passes through (-33, -27) and (-32, -25).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answers
Answer: 2.
Step-by-step explanation:
You can find the slope between two points by using the "rise-over-run" method.
This method essentially calculates the slope as the quotient of the vertical span and horizontal span of the two points.
You can find it through this formula:
\(s = \frac{y2 - y1}{x2 - x1}\)
To find the slope, use two points, (x1, y1) and (x2 and y2).
For the points given, I will replace those values in the formula with (-33, -27) and (-32, -25).
\(s = \frac{-27 - (-25)}{-33 - (-32)}\\\\s = \frac{-2}{-1}\\\\s = 2\)
The slope of the line is 2.
Answer:
\( = 2\)
Step-by-step explanation:
\(( - 33 \: \: \: \: - 27) = > (x1 \: \: \: \: y1) \\ ( - 32 \: \: \: \: - 25) = > (x2 \: \: \: \: y2)\)
\(slope \\ = \frac{y1 - y2}{x1 - x2} \\ = \frac{ - 27 - ( - 25)}{ - 33 - ( - 32)} \\ = \frac{ - 27 + 25}{ - 33 + 32} \\ = \frac{ - 2}{ - 1} \\ = 2\)

the first term of a geometric sequence is 2, and the common ratio is 3. what is the 8th term of the sequence?1,458813,1224,374
Answers
The 8th term of the sequence is 4374. A geometric sequence is a sequence in which each term after the first is obtained by multiplying the previous term by a fixed, non-zero number called the common ratio.
To find the 8th term of the geometric sequence, we can use the formula for the nth term of a geometric sequence:
an = a1 x r^(n-1)
where an is the nth term, a1 is the first term, r is the common ratio, and n is the term number.
Given that the first term is 2 and the common ratio is 3, we have:
a1 = 2
r = 3
Plugging in n = 8, we get:
a8 = 2 x 3^(8-1)
a8 = 2 x 3^7
a8 = 2 x 2187
a8 = 4374
In summary, a geometric sequence is a sequence in which each term is obtained by multiplying the previous term by a constant called the common ratio. In this case, the first term is 2 and the common ratio is 3. We can use the formula an = a1 x r^(n-1) to find the nth term of the sequence. By plugging in n = 8, we get the 8th term of the sequence as 4374.
