Answer:
The inequalities that must be satisfied is
Step-by-step explanation:
Let the number of Heineken bottles be x
Let the number of monster drink bottles be y
Her crate cannot hold more than 32, This situation can be represented as
That is
------------------------(1)
Cost of one Heineken bottles = $800
Cost of one monster drink bottles = $250
then
x

Answer:
Total number number of cars which do not have defects = 539
and 21 are defected out of 560 i.e. 560 - 539 = 21
Step-by-step explanation:
Total cars checked by Car factory = 320
Number of defected cars = 12
The number of cars which do not have defects = 320 - 12 = 308
Total Number of cars = 560
So the equation becomes
⇒
⇒
⇒
Therefore, total number number of cars which do not have defects = 539
and 21 are defected out of 560 i.e. 560 - 539 = 21
Answer:
1.1264
Step-by-step explanation:
Given : An experiment using 35 guinea pigs is set up to study the weight of the pigs after injecting them with a drug.
To Find: If the population mean is 23.5 grams with a standard deviation of 3.4 grams, what is the margin of error of the sample mean?
Solution:
n = 35
Confidence interval = 95%. So, z =1.96
Margin of error =
Margin of error =
Margin of error =
Hence the margin of error of the sample mean is 1.1264.
