Answer:

* Here we assume that the coin tossed is fair.

Probability of event A = # Favorable cases for event A/ # Exhaustive cases for event B

Where

Favorable cases means outcomes of an experiment that favors a particular event

Exhaustive cases means, number of total possible outcomes.

For tossing a coin one time:

# Favorable cases = 1 (getting head)

# Exhaustive cases = 2 (two outcomes, say, head and tail)

So, P(getting head in a single toss) = 1/2

For tossing a coin two times:

# Favorable cases = 1 (getting 2 heads, say, HH)

# Exhaustive cases = 2*2 or 2^2 (4 outcomes, say, HH, HT, TH, TT)

So, P(getting 2 heads in two tosses of a coin) = 1/4

Similarly, for tossing a coin five times:

# Favorable cases = 1 (getting 3 heads, say, HHHHH)

# Exhaustive cases = 2*2*2*2*2 or 2^5 (32 outcomes, say, HHHHH, THHHH, ..... etc)

So, P(getting head in 5 tosses of a coin) = 1/32

Answer:

Step-by-step explanation:

Let w represent the width. Then the length is 2w-5, and the perimeter is ...

  P = 2(L+W)

  44 = 2((2w-5) +w)

  44 = 6w -10

  54 = 6w

  9 = w

  2(9) -5 = 13 = length

The length of the rectangle is 13 meters; the width is 9 meters.

Answer:

150 kg

Step-by-step explanation:

here is the complete question

A rectangular gate is made using 6 straight pieces of steel.

5 m

12 m

The weight of the steel is 2.5 kg per metre.

Work out the total weight of the steel gate.

To solve this question determine the square root of 12 and 5

√169 = 13

5 + 12+ 5 + 12+ 13 + 13 = 60 m

total weight = 60 x 2.5 = 150kg

Answer:

16286

Step-by-step explanation:

the formula for surface area for a sphere is 4 pi r^2

So substitute for r and you get  4pi*1296 then do 3.14 * 4 * 1296 and you get 16286.02 then round it to one decimal (it cancels out) and you get 16286.

6x + 2 = 62

6x + 2 - 2 = 62 - 2

6x = 60

6x / 6 = 60 / 6

Answer:

Step-by-step explanation:

2x - 5 ≤ 6

Add 5 to both sides

2x -5 +5 ≤ 6 +5

2x ≤ 11

Divide both sides by 2

2x/2 ≤ 11/2

x ≤ 5.5

Answer: 11/23

Step-by-step explanation:

I used my calculator to convert those fractions into decimal form and found the biggest number. It was about 0.4789.

The largest fraction will be 11/23.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

All the fractions are,

⇒ 9/19, 5/11, 7/15, and 11/23

Now,

Since, All the fractions are,

⇒ 9/19, 5/11, 7/15, and 11/23

Here, The values are,

⇒ 9 /19 = 0.47

⇒ 5/11 = 0.45

⇒ 7/15 = 0.46

⇒ 11/23 = 0.48

Thus, The largest value of the fraction = 11/23

Answer:

θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

Step-by-step explanation:

Since the integration is in cylindrical coordinates, θ is integrated from 0 to 2π.

Since r = cosθ

when θ = 0, r = cos0 = 1

when θ = 2π, r = cos2π = -1

Since the region is bounded below by the plane z = 0, and on the top by the paraboloid z = 3r², z is integrated from z = 0 to z = 3r².

So, when r = 1, z = 3r² = 3(1)² = 3

when r = -1, z = 3r² = 3(-1)² = 3

So, the limits of integration of  

∭f(r,θ,z)dz r dr dθ are θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

-4 = y-2 ==> y = -2

Answer:

y=-2

Step-by-step explanation:

For a line containing the points (X1,Y1) and (X2,Y2), the gradient/slope is equal to (Y2-Y1)/(X2-X1).

Therefore for a line with gradient -2 and points (3,2) and (5,y), we can say:

-2=(y-2)/(5-3)

-2(2)=y-2

y=-4+2

y=-2

Answer:

x^2+y^2=6^2

Step-by-step explanation:

The equation of a circle is (x-h)^2+(y-k)^2=r^2

where h is the x coordinate of the center, k is the y coordinate of the center, and r is the radius of the circle.

We can see the center is on 0,0, and the radius is 6, so our equation is

(x-0)^2+(y-0)^2=6^2

or

x^2+y^2=6^2

Answer:

[tex] x ^2 + y^2 = 36 [/tex]

Step-by-step explanation:

Center of the circle (h, k) =(0, 0)

Radius of the circle (r) = 6 units

Equation of circle in center radius form is given as:

[tex] (x-h) ^2 + (y-k) ^2 = r^2 [/tex]

[tex] (x-0) ^2 + (y-0) ^2 = (6)^2 [/tex]

[tex] x ^2 + y^2 = 36 [/tex]
