Answer:
0.7969
Step-by-step explanation:
Given that: A sample of size n= 49 is obtained. The population mean is m= 80 and the population standard deviation is s = 14.
The z score measures the number of standard deviation by which the raw sore is above or below the mean. It is given by the equation:
For x = 78.3, the z score is:
For x = 85.1, the z score is:
P(78.3<x<85.1) = P(-0.85<z<2.55) = P(z<2.55) - P(z<-0.85) = 0.9946 - 0.1977 = 0.7969
Remove parentheses:
-4 - 6i + 3i - 8 + i
Combine common terms
-12 -2i
Answer:
23 or more chairs.
Step-by-step explanation:
There are 5 tables to start. Each tables is 450 dollars.
5x450=2250
4500-2250=2250
2250(money still need to be made) divided by 100(the price of a chair)=22.5
Since you can't have a half of a chair but you cant have any less, you round it up to 23 chairs. The answer is 23 or more chairs.
Ok so 7 times 4 is 28 so she read 28 the first day. For the second day since 40-28= 12, 12 divided by 2 is 6. So she read 6 pages per hour.
