A cross section is the 2D shape that fallouts from cutting a 3D with a plane.To classify the face shape from cuts made parallel and perpendicular to the bases of right dimensional figures, we need to know first what parallel cuts are. These cuts will form the shape of the base while perpendicular cuts will take the form of the lateral face. Cuts at an angle through the right rectangular prism or pyramid will make a parallelogram.

During summer weekdays, boats arrive at the inlet drawbridge according to Poisson distribution at a rate of 3 per hour. In a 2-h
mrs_skeptik [129]

Answer:

The probability that no boats arrive is 2.48\times 10^{-3}.

Step-by-step explanation:

Poisson distribution:

Poisson distribution is a statistical distribution that helps to find out the probability of a certain is likely occur a specified period of time.

P(X=x)=\frac{e^{-\lambda t}(\lambda t)^x}{x!}

\lambda = rate.

Given that, Poisson distribution at a rate of 3 per hour.

\lambda = 3

t=2

x=0

The probability that no boats arrive is

P(X=0)=\frac{e^{-2\times 3}(2\times 3)^0}{0!}

                =2.48\times 10^{-3}

mixer [17]

Answer:

226

Step-by-step explanation:

Area of rectangle:

x+6=17

x=11

11+6=17

11+3=14

17×14=238

Area of triangle:

\frac{1}{2}  \times b \times h

Use phytagoras theorem to find the base of the triangle:

c²=a²+b²

5²=4²+b²

25=16+b²

b²=25-16

b²=9

b=√9

b=3 (only the half)

b=6 (the whole base)

\frac{1}{2}  \times 6 \times 4

3×4

12

Shades region:

238-12

=226

What is the inverse of y = 16x^2 + 1
tankabanditka [31]
X = 16y^2 + 1
x - 1 = 16y^2
(x - 1)/16 = y^ 2
( (x-1) / 16 ) ^1/2 = y
( (x-1) ^ 1/2 ) / 4 = y
