There are 20 cars competing in a race. In how many ways can the cars be awarded first, second, and third place? Please help me!

Answer:

The answer is "32 and 4.6648".

Step-by-step explanation:

binomial distribution of x

probability of sucess[tex](P)=32\%=0.32[/tex]

randomly selected number by giraffes [tex]n=100[/tex]

now

[tex]\mu_x=np\\\\[/tex]

    [tex]=(100)(0.32)\\\\=32\\\\[/tex]

[tex]\Sigma_x=\sqrt{np(1-p)}[/tex]

     [tex]=\sqrt{100(0.32)(1-0.32)}\\\\=\sqrt{21.76}\\\\= 4.664761\\\\=4.6648[/tex]

Step-by-step explanation:

Answer:

X=25

Step-by-step explanation:

All angles of a triangle add up for 180

We know that there is a 90 degree right angle.

So (x+25)+(2x-10)=180-90

Remove parenthesis since they don't matter in this problem.

x+25+2x-10=90

Combine similar terms

3x+15=90

Subtract 15 from both sides

3x=75

Divide both sides by 3

x=25

Answer:

The parallelogram ABCD is what makes the parallelogram.

The proof given was AC and BD bisect each other.

Bisect means to divide into 2 parts. AC and BD both divide into 2 parts with each other.

But the lines need to be in 2 equal parts.

So if we were to divide it in that case, it would be able to bisect.

This is given proof that parallelogram ABCD is a parallelogram.

Answer:

Solution given:

ABCD is a parallegram.

In ∆ADE and ∆BCE

AD=BC[corresponding side of parallelogram are equal]

<AED=<BEC[ vertically opposite angle]

<ADE=<EBC[alternate angle]

so

∆ADE are congruent to ∆BCE by S.A.A. axiom

we have

DE=BE[corresponding side of congruent triangle are equal]

Similarly

AE=CE

we have

AC=BD

AE+CE=BE+DE

2AE=2BE

AE=BE

so.we can rightly say that AC and BD bisect each other.

Answer: D.

Step-by-step explanation: You can't have 2 y of the same y axis numbers in a function and A isn't correct because it doesn't go in order.

Answer:

(a) 1

Step-by-step explanation:

In each outcome triplet, each flip has a chance to be H or T. Thus, the following describes all the possible outcomes:

We see that the only option without one tail is the first one, HHH, so the answer is (a) 1.

Step-by-step explanation:

I think its a normal 7 and a normal 3 then a -4 and a -9 and a -10

Answer:

7.) x = 12

9.) x = 4

Step-by-step explanation:

7.) Angle Y and Angle X both add up to 180

=> 40 + 12x - 4 = 180

=> 36 + 12x = 180

=> 12x = 180 - 36

=> 12x = 144

=> x = 12

9.) Angle W and Angle X add up to 180

=> 145 + (-1) + 9x = 180

=> 144 + 9x = 180

=> 9x = 180 - 144

=> 9x = 36

=> x = 36 / 9

=> x = 4

Hope this helps!

Answer:

([-3], [0]), ([3], [0])

Step-by-step explanation:

The given equation of the hyperbola is presented as follows;

[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = 1[/tex]

The vertices of an hyperbola (of the form)  [tex]\dfrac{x^2}{a^2} - \dfrac{y^2}{b^2} = 1[/tex] are (± a, 0)

The given hyperbola can we presented in a similar form as follows;

[tex]\dfrac{x^2}{9} - \dfrac{y^2}{49} = \dfrac{x^2}{3^2} - \dfrac{y^2}{7^2} = 1[/tex]

Therefore, by comparison, the vertices of the parabola are (± 3, 0), which gives;

The vertices of the parabola are ([-3], [0]), ([3], [0]).

Step-by-step explanation:

-30/100 * 140 = 420/10, 0 gets canceled, so x= 42

-64/100 * 40/1 = 64 *4/10 = 256/10 (simplify by 2) = 128/5 (I'm not sure on this one)

Step-by-step explanation:

3, 6, 12, 24, 48, 96, 192, 384, 768, 1536

Answer:

1536

Step-by-step explanation:

10th term=a x r^(9)

where a is first term and r is common ratio

a=3

r=6/3=2

10th term = 3. x. 2⁹

10th term= 3 x 512

10th term= 1536

Answer:

113.112cm^3

Step-by-step explanation:

Given data

Height= 12cm

Diamter= 6cm

Radius= 3cm

The expression for the volume of a cone is given as

V= 1/3*πr^2h

Substitute

V= 1/3*3.142*3^2*12

V=  1/3*3.142*9*12

V=  1/3*339.336

V=113.112cm^3

Hence the volume is 113.112cm^3

Answer:

33(5/6) sq miles

Step-by-step explanation:

Area = LxW

812 = 24xW

Divide by 24

W = 33.8333333 ( 33 (5/6)

8 is non repeating

3 is repeating

For nominator subtract the non repeating    (83-8 = 75)

For  denominator :  one 9 for each non repeating,one zero for each repeating (only 3 is repeating,then one zero)

  75/90  = 5/6
