Answer:

26 centilitres.

Explanation:

First, we start by recalling the standard conversion between millilitres and centilitres.

Let 260 milliliters = x centiliters

We express it as a ratio:

Cross multiply to solve for x:

Therefore, 260 millilitres is 26 centiliters.

The expected value of the proposition is $22.6

The given parameters are

Represent 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

Answer:

L x W =   8.5 x 24    or     12 x 17

Step-by-step explanation:

x  (41 -2x) =204

-2x^2 + 41x -204 = 0      Use Quadratic Formula to find x = 8.5 or 12

(x-8.5)(x-12) = 0

         two sides = 8.5       and river/third side =  24

      or  two sides 12     and river/thirdside = 17

Let's simplify the following equation

given: 100 cm = 1 meters

We need to convert 4 m to cm

so,

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 final amount = $1610

The time period = 15 years

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

Hence, 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 graph of the linear function and it's inverse is given at the end of the answer.

The inverse function is: [tex]h^{-1}(x) = -6x + 55[/tex]

To find the inverse function, we exchange x and y in the original function, then isolate y.

In the context of this problem, first we have to find the function h(x), which is a linear function going through points (1,9) and (3,2), hence the slope is given by:

m = (2 - 1)/(3 - 9) = -1/6.

Then:

y = -x/6 + b.

When x = 1, y = 9, hence we can find the intercept b as follows:

9 = -1/6 + b

b = 54/6 + 1/6

b = 55/6.

Then the equation is:

h(x) = -x/6 + 55/6

Then:

y =  -x/6 + 55/6

6y = -x + 55

6x = -y + 55

y = -6x + 55.

Hence the inverse function is:

[tex]h^{-1}(x) = -6x + 55[/tex]

Formula for the trigonometry is y = b sin ( πx/2 - π/2) + 4

y = A sin( ωx + δ) + b

period: t = 4

ω = 2π/t = 2π/4 = π/2

A = 10 -(-2)/ 2

  = 6

b = (10-2)/2

  = 4

y = b sin (πx/2 + δ) + 4

x = 0, y = bsinδ + 4 = -2

sinδ = -1   => δ = -π/2

y = b sin( πx/2 - π/2) + 4

The measure of the fourth angle that is x and the value is 133°

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

The factor by which the current changes if the resistance increases 10% is; 90.9% reduction

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%

The Fundamental Counting Theorem states that if there are n independent trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, the total number of outcomes is given according to the following rule:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

Answer:

x-intercept: (-0.5,0)

y-intercept: (0,1)

Slope: 2

Domain: All real values

Range: All real values

Step-by-step explanation:

x-intercept:

The x-intercept is the value of x when y = 0. In this graphic, we have that when y = 0, x = -0.5. So the x-intercept is given by: (-0.5,0)

y-intercept:

The y-intercept is the value of y when x = 0. In this graphic, we have that when x = 0, y = 1. So the y-intercept is given by: (0,1).

Slope:

To find the slope, we select two points. The slope is given by the division of the change in y by the change in x.

Two points: (-0.5, 0) and (0,1)

Change in y: 1 - 0 = 1

Change in x: 0 - (-0.5) = 0 + 0.5 = 0.5

Slope: 1/0.5 = 2
