Answer:

\bar X =  31.09

Midrange = \frac{50+8}{2}= 29.00

\bar G = (x_1 *x_2*...*X_{32})^{\frac{1}{32}} = 28.33

If we Trim the top and bottom 14% from the data we need to eliminate 32*0.14 =4.48 so we need to eliminate approximately 5 values from each tail and we got:

16 20 20 22 25 27 29 31 32 32 32 34  34 35 36 36 37 38 39 41 42 43

And the mean calculated from this data is :

\bar X_{T}= 31.86

Step-by-step explanation:

For this case we have the following data:

27 11 36 22 36 12 35 37 50 16 31 45 48 14 20 34 46 15 25 41 34 39 42 29 32 32 8 32 20 38 43 45

And we can calculate the mean with this formula:

\bar X =\frac{\sum_{i=1}^n X_i}{n}

And replacing we got:

\bar X =  31.09

The mid range is calculated with this formula:

Midrange = \frac{High +Low}{2}

And replacing we got:

Midrange = \frac{50+8}{2}= 29

Since the sample size is n =32 we can calculate the geometric mean with this formula:

\bar G = (x_1 *x_2*...*X_{32})^{\frac{1}{32}} = 28.33

For the trimmed mean we need to sort the dats on increasing order and we got:

8 11 12 14 15 16 20 20 22 25 27 29 31 32 32 32 34  34 35 36 36 37 38 39 41 42 43 45 45 46 48 50

If we Trim the top and bottom 14% from the data we need to eliminate 32*0.14 =4.48 so we need to eliminate approximately 5 values from each tail and we got:

16 20 20 22 25 27 29 31 32 32 32 34  34 35 36 36 37 38 39 41 42 43

And the mean calculated from this data is :

\bar X_{T}= 31.86

A = P(1 + rt)

Where:

<span>·         </span>A = Total Accrued Amount (principal + interest)

<span>·         </span>P = Principal Amount

<span>·         </span>I = Interest Amount

<span>·         </span>r = Rate of Interest per year in decimal; r = R/100

<span>·         </span>R = Rate of Interest per year as a percent; R = r * 100

<span>·         </span>t = Time Period involved in months or years

A = 15,000(1+ 0.07(5))

A = 20,250 they acquired in total for 5 years

The yearly amount the get is 15,000 xx 0.07 = $ 1050 per year

So in the next 25 years addition of 1050x25 = $26250 they will get

The sum of two numbers is 148. The larger number is two less than three times the smaller. What are the two numbers?
Lyrx [107]
Let
x--------->  the larger number
y---------> the smaller number

we know that
x+y=148------> equation 1
x=3y-2------> equation 2

substitute 2 in 1
[3y-2]+y=148--------> 4y=150---------> y=150/4------> y=37.5
x=3y-2----> x=3*37.5-2-----> x=110.5

the answer is
the larger number is 110.5
the smaller number is 37.5

Ymorist [56]

Answer:

<em>1 cm^2 : 9 m^2</em>

Step-by-step explanation:

The scale factor of an area is the square of the scale factor of a length.

The scale for lengths is 1 cm : 3 m.

You now square that scale to get the scale of the areas.

Scale of areas:

(1 cm)^2 : (3 m)^2

1 cm^2 : 9 m^2

I need help with 5 and 6
8_murik_8 [283]

Answer:

w = 6

RS = 13

Step-by-step explanation:

RS + ST = RT

(2w + 1) + (w - 1) = 18

3w = 18

; w = 6

Hence the value of RS = 2(6) + 1

; RS = 13

AC = AB + BC

56 = (x + 16) + (5x + 10)

56 = 6x + 26....then rearrange the equation to form...;

56 - 26 = 6x

30 = 6x...

where...; x = 5

AB = 5 + 16 and BC = 5(5) + 10

;AB = 21 ;BC = 35
