WANR - 22%
WCLM - 24%
WWCN - 41%
WKOD - 13%

The ratio of WANR to WCLM is 22:24  OR 11:12
Ratio of WANR to the whole is 22:100 OR 11:50
Ratio of WCLM to the whole is 24:100 OR 12:50

Answer: 11/12 is the ratio to express  the number of people who preferred WANR to those who preferred WCLM.

Step-by-step explanation:

Let the total number of people= x

So, According to the given diagram,

The number of people who preferred WANR = 22% of x

While, The number of people who preferred WCLM = 24% of x

Therefore, The number of people who preferred WANR/The number of people who preferred WCLM = 22% of x / 24% of x

= \frac{22/100\times x}{24/100\times x} = \frac{22}{24} =\frac{11}{12}

Which is the required answer.

The answer would be 14/15

Find a common denominator that both of the fractions can use. An easy way to do this is simply multiply the denominators together. So for 3/5 you would multiply by 3 to get the fraction 9/15 and then multiply 1/3 by 5 to get 5/15. Add both 9/15 and 5/15 to then get 14/15.

Adam is building a rectangular planter without a top the planter will be 7 feet wide 5 feet wide, 5 feet long, and 9 inches high
Tom [10]
Answer: The surface area of the planter will be 120.5 square feet.

In our shape, we will have 5 sides. The base and the four sides going up from each edge of the base.

The base will be 7 x 5 = 35 square feet.

The front and back side will each be 7 x 0.75 = 5.25 square feet.

The left and right side will each be 5 x 0.75 = 3.75 square feet.

If we add up the 5 faces we get:
35 + 5.25 + 5.25 + 3.75 + 3.75 = 120.5 square feet

I need help on this I am just going to use the picture
Radda [10]

Answer:

D

Step-by-step explanation:

let y = f(x), that is

y = \frac{2x-3}{5}

Rearrange making x the subject

Multiply both sides by 5

5y = 2x - 3 ( add 3 to both sides )

5y + 3 = 2x (divide both sides by 2 ) , then

x = \frac{5y+3}{2}

Change y back into term of x, hence

f^{-1}(x) = \frac{5x+3}{2} → D

Michelin Tire Company wishes to set a minimum mileage guarantee on its new MX100 tire. Tests reveal the mean mileage is 67,900 w
Keith_Richards [23]

Answer:

The minimum guaranteed mileage is  x = 71489.55

Step-by-step explanation:

From the question we are told that

   The mean is  \mu  =  67900

     The standard deviation is  \sigma =  2050

Generally for the probability to be 4% the minimum guaranteed mileage is evaluated as

    P( X  \ge x ) =1-  P( \frac{X - \mu }{\sigma } < \frac{ x -  67900 }{ 2050}  ) = 0.04

\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )

     P( X  \ge x ) =1-  P( Z

=>  P( X  \ge x ) = P( Z

=>    z = \frac{ x -  67900 }{ 2050}

From the z table, the critical value corresponding to 0.96 to the left of the curve is  

         z = 1.751

So

        1.751 = \frac{ x -  67900 }{ 2050}

=>     x = 71489.55
