Surface area will consist of:
2 triangles, 3 rectangles:

Solving for triangles:
A=1/2bh
A=1/2(120)
A=60
60*2 gives us the surface area of both triangular sides.

Solve for rectangles:
(17*20)+(8*20)+(15*20)
(340)+(160)+(300)
(800)

800+120=920
The surface area of the prism is 920 square feet

The number of knots in a particular type of wood has a Poisson distribution with an average of 1.6 knots in 10 cubic feet of the
HACTEHA [7]

Answer:

0.994 = 99.4% probability that a 10-cubic-foot block of the wood has at most 5 knots.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

1.6 knots in 10 cubic feet of the wood.

This means that \mu = 1.6

Find the probability that a 10-cubic-foot block of the wood has at most 5 knots.

P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

In which

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

P(X = 0) = \frac{e^{-1.6}*(1.6)^{0}}{(0)!} = 0.202

P(X = 1) = \frac{e^{-1.6}*(1.6)^{1}}{(1)!} = 0.323

P(X = 2) = \frac{e^{-1.6}*(1.6)^{2}}{(2)!} = 0.258

P(X = 3) = \frac{e^{-1.6}*(1.6)^{3}}{(3)!} = 0.138

P(X = 4) = \frac{e^{-1.6}*(1.6)^{4}}{(4)!} = 0.055

P(X = 5) = \frac{e^{-1.6}*(1.6)^{5}}{(5)!} = 0.018

P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.202 + 0.323 + 0.258 + 0.138 + 0.055 + 0.018 = 0.994

0.994 = 99.4% probability that a 10-cubic-foot block of the wood has at most 5 knots.

If the breadth of rectangle is one-fourth of its length and perimeter in60 CM find the length and breadth of rectangle
Gennadij [26K]

Answer:

Step-by-step explanation:

Let length be x

So breadth will be 1/4x

2(x+1/4x)=60

x+1/4x=60/2=30

find lcm and the lcm would be 4 and make denominators equal and add it

4/4x+1/4x=30

5/4x=30

x=30*4/50=6*4=24

Therefore the length is 24/4=6cm and breadth is 24cm.

15*x+12+10-20=12<br><br><br> WHAT
kupik [55]

Answer:

Step-by-step explanation:

15x + 12 + 10 - 20 = 12

15x + 22 - 20 = 12

15x + 2 = 12

15x = 12 - 2

15x = 10

x = 10/15 which reduces to 2/3

Analyze the solution set of the following system by
blsea [12.9K]

Answer:

The equations in the slope-intercept form

y = - 2 x + 5

y = - 2 x + 3

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

  • m is the slope of the line.
  • b is the y-intercept.

To put any equation in the slope-intercept form state y on the left side, x and the numerical term on the right side, the coefficient of y must be 1.

Let us do that with the given equations

∵ 2x + y = 5

→ Subtract 2x from both sides to move x to the right sides

∴ 2x - 2x + y = 5 - 2x

∴ y = 5 - 2x

→ Switch 5 and - 2x

∴ y = - 2x + 5

∵ 3y = 9 - 6x

→ Divide each term by 3 to make the coefficient of y = 1

∴ \frac{3y}{3}=\frac{9}{3}-\frac{6x}{3}

∴ y = 3 - 2x

→ Switch 3 and - 2x

∴ y = - 2x + 3

The equations in the slope-intercept form

y = - 2x + 5

y = - 2x + 3
