Answer:

Step-by-step explanation:

Surface area

The length of the hypotenuse of the front facing triangle is given by the Pythagorean theorem:

  d^2 = 13^2 +6^2 = 169 +36 = 205

  d = √205

So, the perimeter of that triangle is ...

  P = 13 +6 +√205 = 19 +√205

The total area of the rectangular faces of this triangular prism is then ...

  rectangular face area = (base perimeter)·(prism height)

  = (19 +√205)(7) = 133 +7√205

The area of the two triangular faces will be ...

  triangular face total area = 2·(triangle area) = 2(1/2)(6)(13) = 78

Then the total surface area is ...

  total surface area = rectangular face area + triangular face total area

  total surface area = (133 +7√205) +78

  surface area = 211 +7√205 ≈ 311.22 . . . . square units

__

Volume

The volume is the product of the area of the triangular base and the height of the prism.

  V = Bh

  V = (39)(7)

  volume = 273 . . . . cubic units

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0+1}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

x = -5/3

Step-by-step explanation:

6x-(2x-1) =9x+2(2-x)

6x - 2x - 1 = 9x + 4 - 2x

4x - 1 = 7x + 4

collect like terms

4x - 7x = 4 + 1

-3x = 5

x = -5/3

Answer:

a. The probability that the aircraft is fully occupied = 0.3642

b. The probability that between 1 and 5 (including 1 and  5) passengers do not show up is  = 0.6354

Step-by-step explanation:

From the given information:

We are to compute the probability that:

a. The aircraft is fully occupied( i.e. all the passengers show up)

b. Between 1 and 5 (including 1 and  5) passengers do not show up

Given that:

Percentage of passengers that do not show up  = 2% = 0.02

And the population of the passengers = 50; since 50 tickets are being sold for a specific flight.

Let assume X be the random variable that follows a binomial distribution, thus, the number of passengers from the aircraft with 50 passengers can be represented as:

[tex]X \sim Bin (n = 50, p =0.02)[/tex]

Thus;

The probability that the aircraft is fully occupied i.e. all the passengers show up is:

[tex]= (1 - 0.02)^{50}[/tex]

= 0.98⁵⁰

= 0.3642

Hence, The probability that the aircraft is fully occupied = 0.3642

b.  The probability that between 1 and 5 (including 1 and  5) passengers do not show up is:

= P(X = 1) + P(X =2) + P(X = 3) + P(X = 4) + P(X = 5)

= [tex]=(^{50}_1) 0.02(1-0.02)^{50-1} +(^{50}_2) 0.02(1-0.02)^{50-2} + (^{50}_3) 0.02(1-0.02)^{50-3} + ... + (^{50}_5) 0.02(1-0.02)^{50-5}[/tex]

[tex]=(^{50}_1) 0.02(0.98)^{49} +(^{50}_2) 0.02(0.98)^{48} + (^{50}_3) 0.02(0.98)^{47} + ... + (^{50}_5) 0.02(0.98)^{45}[/tex]

= 0.6354

Hence, The probability that between 1 and 5 (including 1 and  5) passengers do not show up is  = 0.6354

Answer:

7. 33%

6. 75%

8. 67%

Step-by-step explanation:

5. 80-15=65

65/85=0.8125 => 81%

6. 100-25= 75

75/100= 0.75=> 75%

7. 60-40=20

20/60=0.333333=>33%

8. 39-13=26

26/39=0.666666667=67%

Answer:

The value is  [tex]P( p < 0.27 ) = 0.67792[/tex]

Step-by-step explanation:

From the question we are told that

      The population proportion is  p= 0.25

       The sample size is  n  =  100

Generally given that the sample size is sufficiently large n > 30  , the mean of this sampling distribution is mathematically represented as

          [tex]\mu_{x} = p = 0.25[/tex]

Generally the standard deviation is mathematically represented as

          [tex]\sigma = \sqrt{ \frac{ p(1 - p)}{n} }[/tex]

=>       [tex]\sigma = \sqrt{ \frac{ 0.25 (1 - 0.25 )}{100} }[/tex]      

=>       [tex]\sigma = 0.0433[/tex]

Generally the probability that less than 27 percent (0.27)of the sample expect their lives to be better in five year is mathematically represented as

      [tex]P( p < 0.27 ) = P( \frac{ p - \mu_{x}}{\sigma} < \frac{0.27 - 0.25 }{ 0.0433} )[/tex]

[tex]\frac{p -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ p )[/tex]

=>     [tex]P( p < 0.27 ) = P( Z< 0.4619 )[/tex]

From the z table the area under the normal curve to the left corresponding to 0.4619 is

     [tex]P( Z< 0.4619 ) = 0.67792[/tex]

     [tex]P( p < 0.27 ) = 0.67792[/tex]

adding 12.5

Step-by-step explanation:

12.5 --> 25 through +12.5

25 --> 37.5 through +12.5

37.5+12.5 = 50 = 50

Answer:

You are adding 12.5 every time.

Step-by-step explanation:

12.5+12.5=25

25+12.5= 37.5

37.5+12.5=50

2.5

Step-by-step explanation:

Answer:

2 1/2cm  is the answer for w

Step-by-step explanation:

the reason for this is because the total area for the triangle is 17 cm

and from whats shown on the rectangle it has only 12 so far so that means the w equals 2 1/2 because 12 + 2 1/2 + 2 1/2 = 17 so therefor the answer is 2 1/2cm

hope this helps :)

Answer:

y<5/3

Step-by-step explanation:

3y+5<10

subtract 5 on both sides

3y<5

divide both sides with 3

y<5/3

Answer:

Step-by-step explanation:

You take the plus 5 and subtract it from 10

So then you have 3y<5

So then you divide both sides by 3

So you get y<5/3
