from 1970 to 1980 the consumer price index increased from 38.8 to 82.4. If a container of onion dip cost $0.48 in 1970 and the p
Vikki [24]
We need to find the percent increase from 38.8 to 82.4, so

x * 38.8 = 82.4
x = 82.4/38.8
x = 2.1237

Multiply by 100 to convert to percentage (move decimal 2 places to the right)

2.1237 = 212.37%

Now we can apply this percentage increase to the onion dip...

0.48 x 212.37% =
0.48 x 2.1237 = 1.019 
 
Round to the nearest cent $1.02 is the amount of increase.  Now add it to the original price to get today's price...

$1.02 + .48 = $1.50

In a certain lake, trout average 12 in. in length with standard deviation 2.75 in. and the bass average 4 lb. in weight with sta
NISA [10]

Answer:

The bass fish was the better catch

Step-by-step explanation:

From the question we are told that

     The  population mean for trout is  \mu_1  =  12 \ in

     The  standard deviation is  \sigma_1  =  2.75  \  in

      The  population mean for  base  is  \mu _2  =  4 \ lb

      The standard deviation is  \sigma_2  =  0.8 \ lb

      The number of  trout caught   x_1  =  18

     The number of  bass caught  x_2  =  6

Generally z-value(standardized value ) for the of number  trout caught  is mathematically represented as

        z_1 = \frac{x_1 -  \mu_1}{\sigma_1 }

substituting value

       z_1 = \frac{18 -  12}{2.75 }

       z_1 = 2.18

Generally z-value(standardized value ) for the of number  bass caught  is mathematically represented as

        z_2 = \frac{x_2 -  \mu_2}{\sigma_2 }

substituting value

       z_2 = \frac{6 -  4}{0.8 }

       z_2 = 2.5

From our calculation we see that  z_2 >  z_1

The  fish that was the better catch is the bass fish
