Answer:

[tex]\frac{2}{13}[/tex]

Step-by-step explanation:

Find the probability by dividing the number of fixed gear bikers by the total number of bikers in the parade.

Since there are 8 fixed gear bikers and 52 bikers in total, this will be found by dividing 8 by 52.

So, the probability as a fraction is [tex]\frac{8}{52}[/tex]

This can be simplified by dividing both the numerator and denominator by 4:

= [tex]\frac{2}{13}[/tex]

So, the probability is [tex]\frac{2}{13}[/tex]

Mid - point = ( 2 , 1 )

Step-by-step explanation:

Let A = ( - 4 , 2 ) and B = ( 8 , 0 )

Let P = ( x , y ) be the mid-point of AB

Then,

     [tex]P = (\frac{x_A + x_B}{2} , \frac{y_A + y_B}{2} ) \\\\P =(\frac{-4+8}{2} , \frac{2+0}{2}) \\\\P = ( \frac{4}{2} , \frac{2}{2} )\\\\P = ( 2 , 1)[/tex]

Answer:

(2,1)

Step-by-step explanation:

Hi there!

Midpoint: [tex](\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )[/tex] where two endpoints of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (-4,2) and (8,0)

[tex](\frac{-4+8}{2} , \frac{2+0}{2} )\\(\frac{4}{2} , \frac{2}{2} )\\(2, 1)[/tex]

Therefore, the midpoint of the line segment is (2,1).

Answer:

Step-by-step explanation:

5 red

3 blue

6 white

2 green

total 16 marbles.

Note: P(E) = probability of event E happening

P(~E) = probability of event E NOT happening.

We usually leave probabilities in fractions whenever possible because they will not be subject to round-off errors.

A. choose one marble at random.

P(W) = 6 white / 16 total = 3/8

B. choose one marble at random.

P(~R) = (16-5)/16 = 11/16

C. choose one marble at random, then a second one without replacement,

there will be 3 blue out of 16 at the beginning, then if successful, there will be 2 blue out of 15.

P(BB) = (3/16)*(2/15) = 1 / 40

D. choose two with replacement

5 red out of 16 for first draw, still 5 red out of 16 for second draw.

P(RR) = (5/16)^2 = 25/256

Answer:

81 cm^3

Step-by-step explanation:

We know that we have to use 3 for pi.

Formula given for formula of cone is:

πr^2h ÷3

Use formula with the given pi and dimensions:

3(3^2)(9) ÷ 3

= 3(9)(9) ÷ 3

= 243 ÷ 3

= 81

Volume is measured in cubic centimeters.

FINAL ANSWER:

81 cm^3

Hope this helps!

Answer:

Yes

Step-by-step explanation:

We can see step by step how to solve for x, and get 11.5:

2x+9=32

Subtrract the 9 from both sides. You should always try to get the number on one side, and the variable on the other:

2x+9-9=32-9

=

2x=23

In the end, once the number values are on one side, and the variable value on the other, you want you varaible to be 1.

When I mean 1, I mean you want 1x, or just x.

Here we see 2x=23, meaning we need to divide both sides by 2, to get 1x:

2x/2=23/2

=

x=11.5

So x equals 11.5, and you were correct.

Hope this helps!

Answer:

geometric

arithmetic

Step-by-step explanation:

there are no statements to check. you did not copy them in.

but I can solve the first part of the question.

sequence 1 :

-10, 20, -40, 80, -160, 320, -640, ...

I extended the sequence by a few more terms.

but it is clear that each new term is the previous term multiplied by -2.

since the sequence is built by multiplication, it is geometric.

sequence 2:

15, -5, -25, -45, -65, -85, ...

so, it is clear that each new term is the previous term subtracted by -20.

since the sequence is built by adding or subtracting, it is arithmetic.

Answer:

Length could be 14.05 ft and width 3.41 ft.

Step-by-step explanation:

The volume of the sand in the second box = 24 ft^3.

Let its base be x feet wide and y feet long.

Then  2(x + y) < 35.

The volume of sand = 0.5xy ft^3.

So 0.5xy = 24

xy = 48.

x = 48/y

Substituting ih the above inequality:

2(48/y + y) < 35

96/y + 2y < 35

2y^2 - 35y + 96 < 0

Solving 2y^2 - 35y + 96 = 0 gives y = 3.41, 14.09.

So the length  could be 14.05 ft and the width 48/14 = 3.41 ft.

The length could be 14.05 ft and the width will be 3.41 ft.

The volume of the sand in the second box = 24 ft³.

Let its base be x feet wide and y feet long.

Then  2(x + y) < 35.

The volume of sand = 0.5xy ft^3.

So 0.5xy = 24

xy = 48.

x = 48/y

Substituting the above inequality:

2(48/y + y) < 35

96/y + 2y < 35

2y² - 35y + 96 < 0

Solving 2y² - 35y + 96 = 0 gives y = 3.41, 14.09.

So the length could be 14.05 ft and the width 48/14 = 3.41 ft.

==========================================================

Explanation:

The volume of the cone is...

V = (1/3)*pi*r^2*h

V = (1/3)*3.14*(1.25)^2*2.75

V = 4.49739583333333

which is approximate.

-----------

The volume of the sphere is

V = (4/3)*pi*r^3

V = (4/3)*3.14*(0.25)^3 ... note the radius is half the diameter

V = 0.06541666666667

which is approximate as well

-----------

Subtract the two volumes to finish things up

4.49739583333333-0.06541666666667 = 4.43197916666667

The result 4.43197916666667 then rounds to 4.43

This is the approximate amount of empty space in the cone that isn't taken up by the spherical gum. The units are in "cubic inches" or "in^3" for short.

Step-by-step explanation:

we are given

[tex] \displaystyle \frac{ {29}^{3} + {29}^{2} + 30 }{ {29}^{4} - 1} = \frac{1}{28}[/tex]

we want to prove it algebraically

to do so rewrite 30:

[tex] \displaystyle \frac{ {29}^{3} + {29}^{2} + 29 + 1}{ {29}^{4} - 1} \stackrel{ ? }{= }\frac{1}{28}[/tex]

let 29 be a thus substitute:

[tex] \displaystyle \frac{ {a}^{3} + {a}^{2} + a + 1}{ {a}^{4} - 1} \stackrel{ ? }{= }\frac{1}{28}[/tex]

factor the denominator:

[tex] \rm\displaystyle \frac{ {a}^{3} + {a}^{2} + a + 1}{ ({a}^{2} + 1) (a- 1)(a + 1)} \stackrel{ ? }{= }\frac{1}{28}[/tex]

Factor out a²:

[tex] \rm\displaystyle \frac{ {a}^{2} ({a}^{} + 1)+ a + 1}{ ({a}^{2} + 1) (a- 1)(a + 1)} \stackrel{ ? }{= }\frac{1}{28}[/tex]

factor out 1:

[tex] \rm\displaystyle \frac{ {a}^{2} ({a}^{} + 1)+1( a + 1)}{ ({a}^{2} + 1) (a- 1)(a + 1)} \stackrel{ ? }{= }\frac{1}{28}[/tex]

group:

[tex] \rm\displaystyle \frac{ ({a}^{2} +1)( a + 1)}{ ({a}^{2} + 1) (a + 1)(a - 1)} \stackrel{ ? }{= }\frac{1}{28}[/tex]

reduce fraction:

Given:

The function is:

[tex]f(x)=3x-5[/tex]

To find:

The average rate of change of the function between x = 3 and x = 7.

Solution:

We have,

[tex]f(x)=3x-5[/tex]

For [tex]x=3[/tex],

[tex]f(3)=3(3)-5[/tex]

[tex]f(3)=9-5[/tex]

[tex]f(3)=4[/tex]

For [tex]x=7[/tex],

[tex]f(7)=3(7)-5[/tex]

[tex]f(7)=21-5[/tex]

[tex]f(7)=16[/tex]

The average rate of change of the function f(x) between x = a and x = b is:

[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]

The average rate of change of the function between x = 3 and x = 7 is:

[tex]m=\dfrac{f(7)-f(3)}{7-3}[/tex]

[tex]m=\dfrac{16-4}{4}[/tex]

[tex]m=\dfrac{12}{4}[/tex]

[tex]m=3[/tex]

Therefore, the average rate of change of the function between x = 3 and x = 7 is 3.

34 . since the given two figure are similar their corresponding sides are proportonal.

let the missing side be x

take these ratios

15/18 = x/30

do cross multiplication

18*x = 30*15

18x = 450

x = 450/18

x = 25

therefore missing side is 25

35.since they are also similar their corresponding sides are proportional.

let the missing side be x

for this take these ratios

8/12 = 10/x

do cross multiplication

12*10 = 8*x

120/8 =x

15 =x

therefore missing side is 15.
