Answer:

Mean=76

Median=72.5

Step-by-step explanation:

Mean= 70+71+72+73+74+96

                         456/6=76

Median = 70,71,72,73,74,96

               72+73=145/2=72.5

Mean= 76

Median= 72.5

The first step is to rearrange the numbers

70, 71, 72, 73, 74, 96

1. mean= sum of terms/number of terms

= 70+71+72+73+74+96/6

= 456/6

= 76

2. Median can be described as the middle number, the median can be calculated as follows

= 72+73/2

= 145/2

= 72.5

Hence the mean is 76 and the median is 72.5

Least common multiple of 8 and 5 is 40.

1/8 = 5/40

9/5 = 72/40

1/8 + 9/5 = 5/40 + 72/40 = 77/40 = 1 37/40

Answer:3:7

Step-by-step explanation:

Answer:

y = 120

Step-by-step explanation:

y = 4x (corresponding angles)

y + 2x = 180

substitute the value of y into the second equation

4x + 2x = 180

6x = 180

x = 30

now that we have the value of x, plug it into either equation and solve for y

y = 4 (30)

y = 120

Answer:

(f o g)(x) = 4x^2 - 8

Step-by-step explanation:

(f o g)(x) = f(g(x))

f(x) = x^2 - 8

g(x) = 2x

f(g(x))

f(2x) = (2x)^2 - 8

       = 4x^2 - 8

(f o g)(x) = 4x^2 - 8

Answer:  After they've played 8 games, they will have the same amount of money remaining.

Step-by-step explanation:

Represent the number of games by the variable x and the remaining amount of money by the variable y.  

 Deanna's situation can be represented by the equation   y = 15 - 0.75x  

Lisa's situation can be represented by the equation   y = 13 - 0.50x  

Now to find out how many games they will have the same amount of money remaining, you have to use substitution and solve for x.

15 - 0.75x = 13 - 0.50x

-13               -13

        2 - 0.75x = - 0.50x

             +0.75x      +0.75x

  2 =  0.25x  

 x  = 8

Step-by-step explanation:

The height of the given Ferris wheel can be described with the aid of a

sinusoidal function.

The height above the ground in terms of the angle turned, a, is

presented as follows;

The height above the ground in terms of the distance traveled, s, is

presented as follows;

Reason:

The general form of an equation of a Ferris wheel is presented as follows;

f(a) = A·sin(a + C) + D

Where, the amplitude, A = The radius = 37 ft.

D = The midline = Height above the ground + The amplitude

D = A + 0.6 = 37 + 0.6 = 37.6

The 6 O'clock is the lower most position, therefore, at the start, where, 'B·t + C' = 0, we have;

f(a) = A·sin(0 + C) + D

Therefore

f(a) = 37·sin(0 + C) + 37.6 = 0.6

f(a) = 37·sin(C) = 0.6 - 37.6 = -37

[tex]sin(C) = \dfrac{-37}{37} = -1[/tex]

C = sin⁻¹(-1) = [tex]-\dfrac{\pi}{2}[/tex]

The equation of Ferris wheel is presented as follows;

Which gives the equation of the height above the ground (in feet) in terms

of the number of radians, a, you have swept out from the 6 O'clock

position is given as follows; Ferris ;

Part 2

s = a·r = a·A

Therefore;

[tex]a = \dfrac{r}{s} = \dfrac{A}{s} = \dfrac{37}{s}[/tex]

Plugging the value of s into the above equation gives the function that

determines the height above the ground (in feet) in terms of the number of

feet traveled g(s) as follows;

Answer:

1.92

Step-by-step explanation:   niueikieoewdn4u

Answer:

Density is defined as:

Density = mass/volume.

We know that:

For liquid A:

Density = 70kg/m^3

Mass = 1400kg

Then the volume is:

Volume = mass/density = (1400kg)/(70kg/m^3) = 20 m^3

For liquid B:

Density = 280 kg/m^3

Volume = 30m^3

We can find the mass of liquid B as:

mass = density*volume = (280kg/m^3)*(30m^3) = 8400 kg

We know that liquid C is a mixture of liquid A and B.

Then the mass of liquid C will be equal to the sum of the masses of liquid A and B, then:

Mass of liquid C = 1400kg + 8400kg = 9800kg

The same happens for the volume, then:

Volume of liquid C = 30m^3 + 20m^3 = 50m^3

Then the density of liquid C is:

Density of liquid C = (9800kg)/(50m^3) = 196 kg/m^3

Answer: how are you doing this tho

Step-by-step explanation:

The 1/3 of 5/8 as a fraction is 5/24 after applying the arithmetic operation the answer is 5/24.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

1/3 of 5/8 as a fraction

Let x be the fraction:

x = 1/3 of 5/8

Or

x = (1/3)(5/8)

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

After multiplication:

x = 5/24

Thus, the 1/3 of 5/8 as a fraction is 5/24 after applying the arithmetic operation the answer is 5/24.
