Answer:

Step-by-step explanation:The probability of picking the biased coin: P(biased coin)=1/100. The probability of all three tosses is heads: P(three heads)=1×1+99×18100. The probability of three heads given the biased coin is trivial: P(three heads|biased coin)=1.

Find the area of the figure.
seraphim [82]

\huge \bf༆ Answer ༄

At first Divide the figure into two rectangles, I and Il

Area of figure l is ~

  • \sf24 \times (40 - 30)

  • \sf24 \times 10

  • \sf240 \:  \: ft {}^{2}

Area of figure ll is ~

  • \sf 18 \times 30

  • \sf540 \: ft{}^{2}

Area of whole figure = Area ( l + ll )

that is equal to ~

  • \sf240 + 540

  • \sf780 \:  \: ft{}^{2}

I don’t understand how to solve this graph.<br> (Y=MX+B)
Alla [95]

Answer:

The equation of line shown in the graph is \mathbf{y=-\frac{1}{2}x -1}

Step-by-step explanation:

We need to find equation of the line shown in graph.

The equation of line will be in slope-intercept form y=mx+b where m is slope and b is y-intercept.

We need to find slope and y-intercept.

Finding y-intercept

Looking at the graph, we can find y-intercept when x =0, the value of y is known as y-intercept.

So, when x =0, y=-1

So, y-intercept is -1

Finding Slope

Now, for finding slope, consider 2 points on graph

(0,-1) and (-2,0)

Slope can be found using formula: Slope=\frac{y_2-y_1}{x_2-x_1}

We have x_1=0, y_1=-1, x_2=-2, y_2=0

Putting values and finding slope:

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-1)}{-2-0} \\Slope=\frac{0+1}{-2-0} \\Slope=\frac{1}{-2} \\Slope=-\frac{1}{2}

So, slope is m=-\frac{1}{2}

Equation of line

Now, equation of line having slope m=-\frac{1}{2} and y-intercept b = -1 is

y=mx+b\\y=-\frac{1}{2}x -1

So, equation of line shown in the graph is \mathbf{y=-\frac{1}{2}x -1}
