Step-by-step explanation:

as AD bisects them they will be two equal parts so

5x-10=3x+10

5x-3x=10+10

2x=20

divide both sides by 2 and

x=10

5x-10= 3x+10

5x-3x= 10+10

2x÷2= 20÷2

x= 10

Which r-value represents the strongest correlation?<br> –0.83<br> –0.67<br> 0.48<br> 0.79
maks197457 [2]

Answer:

–0.83

Step-by-step explanation:

An r-value, or correlation coefficient, tells us the strength of the correlation in a linear regression.  This number ranges from -1 to 1; -1 is a perfect linear fit for a decreasing set of data, while 1 is a perfect linear fit for an increasing set of data.

The closer the r-value is to either -1 or 1, the stronger the correlation is.

The two negative numbers we have are -0.83 and -0.67.  The first one, -0.83, is 0.17 away from -1.  -0.67, on the other hand, is 0.33 away from -1.  The two positive numbers we have are 0.48 and 0.79.  The first one, 0.48, is 0.52 away from 1.  The second one, 0.79, is 0.21 away from 1.  The one that is closest to the perfect fit is -0.83, since it is only 0.17 away from a perfect fit.

A roulette wheel has the numbers 1 through 36, 0, and 00. A bet on four numbers pays 8 to 1 (that is, if you bet $1 and one of t
Natasha_Volkova [10]

Answer:

Lose $0.05

Step-by-step explanation:

There are 38 possible spots on the roulette wheel (numbers 1 to 36, 0 and 00).

If the player can choose four numbers on single $1 bet, his chances of winning (W) and losing (L) are as follows:

P(W) = \frac{4}{38} \\P(L) = 1-P(W) = 1-\frac{4}{38} \\P(L) = \frac{34}{38}

The expected value of the bet is given by the probability of winning multiplied by the payout ($8), minus the probability of losing multiplied by the bet cost ($1)

EV=\frac{4}{38}*\$8 -\frac{34}{38}*\$1\\EV= -\$0.05

On each bet, the player is expected to lose 5 cents ($0.05).

x^2+2x+9=0 \\ \\&#10;a=1 \\ b=2 \\ c=9 \\ b^2-4ac=2^2-4 \times 1 \times 9=4-36=-32 \\ \\&#10;x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-2 \pm \sqrt{-32}}{2 \times 1}=\frac{-2 \pm \sqrt{-16 \times 2}}{2}=\frac{-2 \pm 4i\sqrt{2}}{2}=-1 \pm 2i\sqrt{2}

The answer is D.
