$59.99 if it where on sake for 25% off
gulaghasi [49]
The item would cost approximately $45. You can do this by taking the price of the item ($60) and multiply by the percent (25%). 60 x 0.25 = 15. That is the discount you would subtract from the item itself. Now you would take the original price ($60) and subtract the discount ($15). 60 - 15 = 45.

mihalych1998 [28]

Answer:

Women has better study habit than men.

Step-by-step explanation:

For knowing who has better study habits and attitudes toward learning we have to find the mean of both the women and men data.

The first step is that we only take first 18 values of both women(X) and men(Y) data, to make them of same length

Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.  

Calculating all values:

\bar{X} = 141.0556

\bar{Y} = 121.25

Thus, women has better study habit than men. Since Mean of X is larger than Mean of Y.

devlian [24]
To compare the answers, you need to have the same denominator. 

We know that, 18 is a common denominator between 6 and 9. 

(5/6)*3/3 => 15/18 (ALMONDS) 
(7/9)*2/2 => 14/18 (CASHEWS) 

As seen, the weight of almonds is 1/18 bigger than the cashews.

Hope I helped :)
