Answer: 577
Step-by-step explanation:
Answer:
577.0
Rounded to the nearest 0.1 or
the Tenths Place.
Step-by-step explanation:
576.984
You rounded to the nearest tenths place. The 9 in the tenths place rounds up to 10 because the digit to the right in the hundredths place is 8.
Because the tenths place was rounded up from 9 to 10, the tenths place becomes 0 and the ones place is increased by 1. When a 9 is rounded up to 10, that place value becomes 0 and we add 1 to the previous place value.
577.0
When the digit to the right is 5 or greater we round away from 0.
576.984 was rounded up and away from zero to 577.0
Convert. 260 milliliters to centiliters.
Answer:
26 centilitres.
Explanation:
First, we start by recalling the standard conversion between millilitres and centilitres.
[tex]10\text{ milliliter = 1 centileter}[/tex]Let 260 milliliters = x centiliters
We express it as a ratio:
[tex]\frac{10\text{ }milliliters}{1\text{ centiliter}}=\frac{260milliliters}{x\text{ centiliters}}[/tex]Cross multiply to solve for x:
[tex]\begin{gathered} 10x=260\times1 \\ x=\frac{260}{10} \\ x=26\text{ centiliters} \end{gathered}[/tex]Therefore, 260 millilitres is 26 centiliters.
Determine if it has a minimum of maximum and what that value is whilst also Identifying the domain and range
Hello!
First, let's rewrite the expression here:
[tex]f\mleft(x\mright)=-2x^2+12x-15[/tex]We will have to find the coefficients a, b and c:
• a ,= -2;
,• b ,= 12;
,• c ,= -15;
As we can see, coefficient a is negative. It means that the parabola will face downwards and have a maximum value.
We can obtain this point by using the two formulas below to calculate the coordinates (x, y) of this point, look:
[tex]\begin{gathered} X_V=\text{ }-\frac{b}{2\cdot a} \\ \\ Y_V=-\frac{b^2-4\cdot a\cdot c}{4\cdot a} \end{gathered}[/tex]As we know the coefficients, let's replace the values in the formulas:
Xv:
[tex]\begin{gathered} X_V=-\frac{b}{2\cdot a} \\ \\ X_V=-\frac{12}{2\cdot(-2)}=-\frac{12}{-4}=-(-3)=+3 \\ \\ X_V=3 \end{gathered}[/tex]Now let's find Yv:
[tex]\begin{gathered} Y_V=-\frac{b^2-4\cdot a\cdot c}{4\cdot a} \\ \\ Y_V=-\frac{12^2-4\cdot(-2)\cdot(-15)}{4\cdot(-2)}=-\frac{144-120}{-8}=-\frac{24}{-8}=-(-3)=+3 \\ \\ Y_V=3 \end{gathered}[/tex]Doing this, we obtained the coordinate of the maximum point (x, y) = (3, 3).
As it doesn't have any restrictions, the domain will be: [-∞, +∞].
[tex]-\infty\: We have one restriction in the range, do you remember which?The maximum value will be when y = 3, so the range is [-∞, 3].
Look at the graph of this function below:
graph the line with the slope -3/2 and y intercept -1
Answer: y = -3/2x - 1
Step-by-step explanation:
y = mx + b
1. m is the slope so substitute -3/2 for m. ( y = -3/2x + b)
2. b is the y intercept so substitute -1 in for b. ( y = -3/2x - 1)

If the player makes the next 3 free throws, I will pay you $39. Otherwise you pay me $43.
Step 1 of 2 : Find the expected value of the proposition
The expected value of the proposition is $22.6
How to determine the expected value?The given parameters are
Proportions of free throws = 359 out of 449Amount paid for making a throw = $39Amount collected for losing a throw = $43Represent the proportion as a fraction
So, we have
p = 359/449
The expected value is then calculated as
E(x) = p * Amount paid for making a throw - (1 - p) * Amount collected for losing a throw
Where p represents the proportion defined above
So, we have
E(x) = 359/449 * 39 - (1 - 359/449) * 43
Evaluate the difference
E(x) = 359/449 * 39 - 90/449 * 43
So, we have
E(x) = 22.6
Hence, the proposition has an expected value of $22.6

The current in a resistor is inversely proportional to the resistance. By what factor will the current change if the resistance increases 10%.
The factor by which the current changes if the resistance increases 10% is; 90.9% reduction
How to Interpret Ohms' Law?
Ohm's law states that the electrical current (I) flowing in a circuit is directly proportional to the voltage (V) and inversely proportional to the resistance(R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change. Thus;
I = V/R
Now, we are told that the resistance increases by 10%.
Thus, New value of resistance = 1.1R
Thus, new current/old current = 1/1.1 = 0.909 = 90.9%

If Montraie is going to invest in an account paying an interest rate of 4.6% compounded annually, then she has to invest $820.06 for the value of the account to reach $1610 in 15 years
The interest rate = 4.6%

The compound interest
A = [tex]P(1+\frac{r}{100})^{t}[/tex]
Where A is the final amount
P is the principal amount
r = interest rate
t is the time period
Substitute the values in the equation
1610 = [tex]P(1+\frac{4.6}{100})^{15}[/tex]
1610 = P×1.96
P = 1610/1.96
P = $820.06

The measure of the fourth angle that is x and the value is 133°
What is an octagon?A regular octagon will have all its sides equal in length. Each interior angle of a regular octagon is equal to 135°. Therefore, the measure of exterior angle becomes 180° – 135° = 45°. The sum of the interior angles of the octagon is 135 × 8 = 1080°.
Let the 8 interior angles of the octagon be:
x-12, x-8, x-4, x, x+4, x+8, x+12, x+16.
Their sum = 8x+16 = 1080, or
this implies 8x = 1080–16 = 1064
thus on further solving we get x = 133
Hence the sixth angle = x+8 =141 degrees.

Using the Fundamental Counting Theorem, the number of length-n sequences that have at least one pair of adjacent LEDs that light up with the same color is:
[tex]N = 4 - 4 \times 3^{n - 1}[/tex]
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, each thing independent of the other, the number of results is given as follows:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In the context of this problem, there are n LEDs, each with 4 possible colors, hence he total number of sequences is:
[tex]T = 4^n[/tex]
For sequences with no repeating LEDs, we have that:
The first LED can have 4 outcomes.Any of the following LEDs can have 3 outcomes. (except the color of the previous one).Hence the number is:
[tex]T_n = 4 \times 3^{n-1}[/tex]
(n - 1) as the first LED is not included on those with 3 possibilities.
Having at least one repeating and no repeating are complementary events, hence the number of sequences is:
