Answer:

Yes

Step-by-step explanation:

0.23 = 23/100.

AS a rational number is defined as a number which can be written as a/b , where a and b are integers, in its simplest form then we can definitely say that 0.23 is rational.

Given:

A figure in which a transversal line intersect the two parallel lines.

To find:

The missing value for the equation $m\angle \_+m\angle BPD=180^\circ$

Solution:

In the given figure, the two parallel lines are line ED and line AB, and CD is the transversal line.

Angle BPC and angle BPD lie on a straight line CD. So,

$m\angle BPC+m\angle BPD=180^\circ$ (Supplementary angles)

Angle APD and angle BPD lie on a straight line AB. So,

$m\angle APD+m\angle BPD=180^\circ$ (Supplementary angles)

Therefore, the required complete equations are $m\angle BPC+m\angle BPD=180^\circ$ and $m\angle APD+m\angle BPD=180^\circ$ .

IgorC [24]

Answer:

The expected value can be calculated as:

Es = x₁*p₁ + x₂*p2 + .....

where xₙ is the event (the amount of money that you win or lose, and pₙ is the probability for the event)

for example, in a 10 side dice, the probability of obtaining a specific number is 1/10.

we have a d10 i guess (a dice with 10 sides, 1 to 10)

if you roll from 1 to 7, nothing happens.

If you roll an 8, you lose $1500

if you roll a 9, you lose $75

if you roll a 10, you lose $2000 (and the game)

the expected value is,

Es = 1/10*(7*0 - 1*$1500 - 1*$75 - 1*$2000) = -$357

in the second case, you start paying $500.

if you roll a 7, you must pay $1000, if else, nothing happens.

Then the expected value is

Es = -$500 - 1/10*(-1*$1000 + 9*$0) = -$600

So the expected value is smaller in this case, so the deal is not fair

Slope of (-7,-2) (9,4)

Olenka [21]

Answer:

m= $\frac{3}{8}$

Step-by-step explanation:

1. Use the slope equation to solve the problem

$\frac{y_{2} -y_{1}}{x_{2} -x_{1} }$

2. Plug in your values into the equation.

$\frac{4-(-2)}{9-(-7)}$

3. Simplify the equation.

m= $\frac{3}{8}$
