Notebooks cost $1.20 each. This weekend they will be $.80 What percentage is the sale?
Answers
he
The amount of discount during the weekend = (1.20 - 0.80) dollars
= 0.40 dollars
So the amount of discount given during the weekend is $0.40
Now we need to find the percentage of discount given during the weekend.
Then
Percentage of discount during the weekend = (0.40/1.20) * 100
= 0.33 * 100
= 33
Then the percentage of discount given is 33%.
1.2-.8=.4 Now divide .4 by 1.2 to get your answer.
.33=33%
You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so
Does you understand it now?

Answer:
The percentage of the data between 580 and 620 is 68.26 %
Step-by-step explanation:
Given,
Mean, = 600,
Standard deviation, = 20,
Using the equation,
Z-score for the data 580 =
While, the z-score for the data 620 =
Using normal distribution table,
P(580 < z) = 0.1587
Also, P(620 > z) = 0.8413
Hence, the percent of the data is between 580 and 620 = P(620 > z) - P(580 < z)
= 0.8413 - 0.1587
= 0.6826
= 68.26 %
z1 = (580-600)/20 = - 1
z2 = (620-600)/20 = + 1
According to the Empirical Rule 68-95-99.7
Mean +/- 1*SD covers 68% of the values
Therefore, required percent is 68%

Final answer:
By applying the provided ratio of hiring employers to the total number of employers, and then multiplying by the average number of new hires per employer, we can conclude that an estimated 2800 new jobs were about to become available in this metropolitan area.
Explanation:
To solve this problem, we must note that 8 in 25 employers were planning to add more employees. This is a ratio of 8/25. With a total of 1250 employers in the area, we can calculate the number of employers that are hiring by multiplying this ratio by the total number of employers: (8/25)*1250 = 400 employers. Each of these employers was set to hire an average of 7 new employees, so we multiply the number of employers hiring by the average number of new hires: 7 new employees * 400 employers = 2800 new jobs. Thus, 2800 new jobs were about to become available in this area.

Answers
Answer:
A) Yes
Step-by-step explanation:
Yes, the events silver and black are mutually exclusive, meaning they cannot not happen at the same time. While a car can certainly be black and silver, a car cannot be mainly silver AND mainly black at the same time. One color is going to be dominant
P (silver OR black)= P(silver) + P(black)
= 0.22 + 0.19
= 0.41
