Answer:

Volume of the figure = 64 cm³

Step-by-step explanation:

Volume of the given figure = Volume of complete cuboid - volume of the cuboid having one face as ABCD

Volume of complete cuboid = Length × Width × Height

                                               = 10 × 2 × 6

                                               = 120 cm³

Volume of the part having one face as ABCD = AB × BF × BC

                                                                            = 7 × 2 × (6 - 2)

                                                                            = 56 cm³

Volume of the given figure in the picture = 120 - 56

                                                                    = 64 cm³

Therefore, volume of the figure = 64 cm³

Answer:

a) Since both np >= 5 and n(1-p) >= 5,  it is reasonable to approximate the sampling distribution of p^‚ using a normal distribution.

b) 0.5 = 50% probability of observing a sample proportion of at 0.658.

Step-by-step explanation:

a. Show that it is reasonable to approximate the sampling distribution of p̂ using a normal distribution.

We need that:

np >= 5

n(1-p) >= 5

Sample of 76, 50 of the children were born were right-handed.

So [tex]n = 76, p = \frac{50}{76} = 0.658[/tex]

np = 76*0.658 >= 5

n(1-p) = 76*0.342 >= 5

Since both np >= 5 and n(1-p) >= 5,  it is reasonable to approximate the sampling distribution of p^‚ using a normal distribution.

b. Assuming left- and right-handed children are equally likely from right-handed parents, what is the probability of observing a sample proportion of at least p̂ =0.658 ?

This is the mean, so 50% below and 50% above.

0.5 = 50% probability of observing a sample proportion of at 0.658.

Answer:

See below.

Step-by-step explanation:

1) 3 congruent sides and 3 congruent angles: equilateral, equiangular, acute

2) 2 congruent sides and a right angle: right isosceles

3) 2 congruent sides and an obtuse angle: obtuse isosceles

4) 1 obtuse angle and all different lengths of sides: obtuse scalene

5) 1 right angle and all different side lengths: right scalene

6) 2 congruent sides, all acute angles: acute isosceles

7) x + 2 = 10

x = 8

8) 10x + 3 + 10x + 3 + 34 = 180

20x + 40 = 180

20x = 140

x = 7

Answer:

Probability = 0.12025

Step-by-step explanation:

P (Am) = 1/50 = 0.02       {Magazine ad}

P (At) = 1/8 = 0.125         {Television ad}

P (Am ∩ At ) = 1/100 = 0.01      {Both ads}

P (Am U At) = P (Am) + P (At) - P (Am ∩ At )

= 0.02 + 0.125 - 0.01

P (Am U At)  = 0.135       {Person sees either ad}

P (Am' ∩ At') = 1 - P (Am U At)

P (Am' ∩ At')  = 1 - 0.135 = 0.865      {Person sees none ad}

Prob (Purchase) = Prob (Purchase with ad) + Prob (purchase without ad)

P (P/ A) = 1/4 = 0.25 , P (P / A') = 1/10 = 0.1

P (P) = (0.25) (0.135) + (0.1) (0.865)

= 0.03375 + 0.0865

0.12025

Answer:

Step-by-step explanation:

6x + 26 = 8x - 12 ( 1 - 3x )

6x + 26 = 8x - 12 + 36x

Doing like terms on one side,

6x -8x -36x = -12 -26

-38x = -38

x = -38 / -38

x = 1

Answer:

interest is $105

total is $455

Step-by-step explanation:

350 * .03 = 10.5

10.5*10 = 105

interest is 105

350 +105 = 455

Interest earned: $105

The balance of the account: $455

Answer:

x=8

Step-by-step explanation:

subtract 9 from 17 to get x alone on one side. 17-9=x+9-9. That will equal 8=x. Hope this helps

Answer:

hello !

x = 8

transpose nine to isolate x:

17 - 9 = x

8 = x

Answer:

Following are the solution to the given points:

Step-by-step explanation:

For point (a) :

In this, two points are  exclusive to one another,  it is a probability that first or the  second project will have breaches,

[tex]\to P = P(A) + P(B)[/tex]

       [tex]= 0.3 + 0.25\\\\= 0.55[/tex]

Since the p(A & B)=0  is mutually exclusive.

For point (b):

[tex]\to P = ( \frac{1 -p(A)) \times P(B)}{((1-P(A)) \times P(B) + P(A&B)}) \\\\[/tex]

       [tex]= \frac{(1 -0.3)\times 0.25}{(1-0.3)*0.25 + 0} \\\\ = 1[/tex]

For point (c):

 if both a and b are independent:

(a):

[tex]P = P(A) + P(B) - P(A)\times P(B) \\\\[/tex]

   [tex]= 0.3 + 0.25 - 0.3 \times 0.25\\\\ = 0.475[/tex]

(b):

[tex]P = \frac{(1 -p(A)) \times P(B)}{((1-P(A)) \timesP(B) + P(A&B))} \\\\[/tex]

   [tex]= \frac{(1 - 0.3)\times 0.25}{((1-0.3)\times0.25 + 0.3\times0.25)}\\\\ = 0.7[/tex]

Answer:

15.24feet

Step-by-step explanation:

Using the method of SOH CAH TOA;

Length of the kite is the hypotenuse = x

If the kite is 10 feet up in the air, then the height = 10feet (opposite)

Angle of elevation = 41 degrees

Sin theta = Opposite/hypotenuse

Sin 41 = 10/x

x = 10/sin41

x = 10/0.6561

x = 15.24 feet

Hence the kite is 15.24feet long

Answer:

D. x+2y=12

Step-by-step explanation:

From the graph we know that the y-intercept is 6. (0,6) and the x-intercept is 12. (12,0)

The graph is going down so the slope is negative, from (0,6) count down to (0,0) and count right 12 unit to reach the x-intercept(12,0) the slope is -6/12 or -1/2.

the equation of the line is y=-1/2+6 or x+2y=12

x+2y=12

2y=-x+12

y=-1/2x+6
