Answer:
The 2 numbers are 512.8 and 487.2.
Step-by-step explanation:
Let the numbers be x and y, then:
x + y = 1000............(1)
x^2 - y^2 = 25600
(x + y)(x - y) = 25600
1000(x - y) = 25600
x - y = 25.6............(2)
Adding (1) + (2):
2x = 1025.6
x = 512.8
so y = 1000 - 512.8
y = 487.2.
Answer:
Third week = 23.35 miles
Step-by-step explanation:
First week total miles = 15 miles
he would like to run 30% more miles each week than the week before
Second week = 15 miles + (30% of 15 miles)
= 15 + (30% * 15)
= 15 + (0.3 * 15)
= 15 + 4.5
= 19.5 miles
Second week = 19.5 miles
Third week = 19.5 miles + (30% of 19.5 miles)
= 19.5 + (30% * 19.5)
= 19.5 + (0.3 * 19.5)
= 19.5 + (5.85)
= 23.35 miles
Third week = 23.35 miles
Answer:
For the sampling distribution of the sample proportion for a sample of size 50, the mean is 0.061 and the standard deviation is 0.034.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean 
and standard deviation 
In this question:
So
Mean:
Standard deviation:
For the sampling distribution of the sample proportion for a sample of size 50, the mean is 0.061 and the standard deviation is 0.034.
Answer:
D.the distance you drive
Step-by-step explanation:
The range of the function is the values of the output
h is the input
60h is the output
60 = miles driven = distance
