Each of three friends flips a coin 70 times. The results for each friend are shown in the tables. Find the relative frequency for the event ​"heads​" for each friend. If the friends combine their results to get 116 heads and 94 ​tails, what is the relative frequency for the event ​"heads​"? Use pencil and paper. Suppose each friend flips a coin 700 times. Is there a value you would expect the relative frequency for the event ​"​heads" to be close​ to?

tan A= [tex]\frac{10}{\sqrt{96} }[/tex]

tan A= [tex]\frac{5\sqrt{6} }{12}[/tex]

Because sine15. 7°=h/2500

=2500×sine15.7°=h

=676 km

this how you will get h

Answer: [tex]\frac{3}{6}[/tex] or 0.5

Step-by-step explanation:

It has 6 sides,  {1,2,3,4,5}. So the total number of cases is 6.

Even number includes  {2,4,6}.  The sample space of rolling an even is 3.

The probability of rolling an even number formula is:

P(Rollinganevennumber)= [tex]\frac{Number of cases in the sample space​}{Total number of cases}[/tex]

The probability of an even number is [tex]\frac{3}{6}[/tex] or 0.5

2 is your right answer ok my friend

The requried range of the radio station is given as 1256 square miles.

The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.

Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles

Thus, the requried range of the radio station is given as 1256 square miles.

Answer:

2=41     1=49      3=49

Step-by-step explanation:

Angle 2 = 41 because it is directly across the given angle.

Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.

41+41=82

180-82=98

98 / 2 = 49

Angles and 3 both equal 49

Answer:

2=41°(Alternate Interior angles)

1=41°(diagonal of rhombus bisects the interior angles)

3=49°(180-82/2)

Answer:

50

Step-by-step explanation:

12x + 15 = 5x +  85   {Subtract 15 from both sides}

12x + 15 - 15 = 5x + 85 - 15  

          12x = 5x + 70        {Subtract 5x from both sides}

12x - 5x   = 70

         7x = 70         {Divide both sides by 7}

          x = 70/7

x = 10

∠U = 5x = 5*10 = 50

Answer:

t = 1 s

Step-by-step explanation:

The function models the height of the ball after t seconds is given by :

[tex]h=32t - 16t^2[/tex]

We need to find how many seconds does it take for the ball to reach its maximum height.

For maximum height put dh/dt = 0

[tex]\dfrac{dh}{dt}=\dfrac{d}{dt}(32t - 16t^2)\\=32-32t[/tex]

So,

32-32t = 0

t = 1

So, it will take 1 second to reach its maximum height.

Answer:

8.9 x 10...........................

Answer:

1260 ways

Step-by-step explanation:

Given

[tex]Dolls = 8[/tex]

[tex]Boxes = 5[/tex]

From the question, we understand that: the boxes are identical; however, the dolls are different.

Since no box can be empty, the following scenario exists:

2, 2, 2, 1, 1

This means that 3 of the 5 boxes will hold 2 dolls each while the other 2 will hold 1 doll each.

 So, the number of selection is as follows:

2 of the 8 dolls will be selected in 8C2 ways

2 of the remaining 6 dolls will be selected in 6C2 ways

2 of the remaining 4 dolls will be selected in 4C2 ways

1 of the remaining 2 will be selected in 1C1 ways

1 of the remaining 1 will be selected in 1C1 ways

[tex]Expression: ^8C_2 * ^6C_2 * ^4C_2 * ^1C_1 * ^1C_1[/tex]

Since the boxes are identical, we have to divide the above expression by 2 to get the number of ways:

[tex]Ways = \frac{^8C_2 * ^6C_2 * ^4C_2 * ^1C_1 * ^1C_1}{2}[/tex]

[tex]Ways = \frac{28 * 15* 6* 1 * 1}{2}[/tex]

[tex]Ways = \frac{2520}{2}[/tex]

[tex]Ways = 1260[/tex]

Find the diagram attached

Area of a parallelogram = Base * Height

Given

Area = 120ft^2

BAse = 20ft

Required

Height

From the formula;

Height = Area/Base

Height = 120/20

Height = 6ft

Hence the value of h is 6ft

Step-by-step explanation:

Answer:

y = -0.5

Step-by-step explanation:

Since 6 can be multiplied to -3, we can make an equation to make 6 turn into -3

6 ÷ -2 = -3

So since we did that with 6, the denominator, we do the same with 1, the numerator

1 ÷ -2 = -0.5

So the new numerator is -0.5, and the new denominator is -3

And the two fractions are the same

Complete question :

Mavis is interested in whether military dependency is related to gender in American Samoa. Here is data she collected about the population of American Samoa in 2010.

Millitary status _________ female ____ Male

In armed forces _________ 28 _______ 59

Millitary dependent ______ 928 ______ 781

Civilian _______________ 26393 ___27330

Answer:

Male = 0.4193

Female = 0.5087

Step-by-step explanation:

To obtain the marginal distribution of gender :

Total number of civilians (male + female)

(26393 + 27330) = 53,723

Male :

P(male) = number of male / total

P(male) = 26393 / 53,723 = 0.4912793

P(Female) = number of Female / total

P(Female) = 27330 / 53,723 = 0.5087206
