We can use the multiplicative rule since these are independent events. If the probability that one given flight takes place is 0.81, then the probability of 3 flights taking place is (0.81)^3 = 0.5314.

A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto
Gre4nikov [31]
\begin{cases}y=2x-2\\y=2x+2\end{cases}\implies\begin{cases}-2x+y=-2\\-2x+y=2\end{cases}

For these lines, let u=-2x+y.

\begin{cases}y=2-x\\y=4-x\end{cases}\implies\begin{cases}x+y=2\\x+y=4\end{cases}

And for these, let v=x+y.

Now,

\begin{cases}u=-2x+y\\v=x+y\end{cases}\implies \begin{bmatrix}u\\v\end{bmatrix}=\underbrace{\begin{bmatrix}-2&1\\1&1\end{bmatrix}}_{\mathbf T}\begin{bmatrix}x\\y\end{bmatrix}

The vertices of S in the x-y plane are (0, 2), (2/3, 10/3), (2, 2), and (4/3, 2/3). Applying \mathbf T to each of these yields, respectively, (2, 2), (2, 4), (-2, 4), and (-2, 2), which are the vertices of a rectangle whose sides are parallel to the u-v plane.

Pooja's plant began sprouting 2days before Pooja bought it, and she had it for 98 days until it died. At its tallest, the plant
taurus [48]

Given that function H(t) models the height of Pooja's plant (in centimeters) where t is the number of days after she bought it.

Now we have to find about which number type is more appropriate for the domain of h. That means what values can be taken by the variable "t".

Since t is number of days not the hours so t will not use decimal or fraction values. It can use integer values for the number of days.

Since time is counted after she bought the plant then number of days will be positive.

Hence answer for the type of domain can be positive integers or you can say integers greater than or equal to 0.

Whenever you're asked to find the best prediction based on the graph, you always use the line of best fit (the black line) that is determined from your data points.

Since 202cm isn't on your graph, you will need to write an equation for your line of best fit and mathematically figure out the arm span. If you look at your graph, notice that for every x value, the y value is equal to it. That makes writing the equation easy. Since x=y, your equation is pretty much just y = x. 

Your x value that you need to plug in is x=202cm. This is because height is on the x axis and the height you want to find the arm span for is 202cm. Plug x=202 into the equation:
y=x
y=202

The arm span <span>of a player that is 202 cm tall is B) 202cm wide.</span>

If the tax rate on homes in Topeka, Kansas is 2.4 percent of their value and Bonnie owns a $100,000 house, how much will the rea
Ksivusya [100]

Answer:

  $200

Step-by-step explanation:

The annual tax bill is ...

  2.4% × $100,000 = $2,400

On a monthly basis, that is ...

  $2400/(12 mo) = $200/mo

Taxes will add $200 per month to Bonnie's mortgage payment.
