.Answer:
Step-by-step explanation:
Part A: 0.7(x)
Part B: 8.96/0.7 ---> (You can solve this by yourself)
For getting the answer, you can assume the regular price of the book is x. Then, the sale price would be x-0.3x, which is 0.7x
For part B, the price is 0.7 of the original. Dividing the number by 0.7 gets you the original price
Answer:
22°
Step-by-step explanation:
If the mean is m and the standard deviation is s, then we can say that the temperatures that fall <em><u>within 1 standard deviation of the mean</u></em> will be:
m - s < temperatures < m + s
To we take the sum of mean and standard deviation: 24 + 4 = 28
and, the different of mean and standard deviation: 24 - 4 = 20
So, <em>the temperature that is in between 20 and 28 is the temperature within 1 standard deviation of the mean</em>.
This is the third answer, 22°
Answer:
3x - 2x
Step-by-step explanation:
The difference - the subtraction symbol
The product of three and a number - 3 multiplied by x (basically says what's the solution to three times x)
Two times the number - 2 times x
