Answer:
It's steepness decreases
Step-by-step explanation:
If you graph both, you can see it's less steep. Sorry I don't know if there's any other faster way.
Answer:
B) approximately normal with mean 2.3 and standard deviation 2
Step-by-step explanation:
Given the following :
Mean crimes per day = 2.3
Standard deviation = 2
Number of samples = 100
Sampling distribution of the mean:
According to the central limit theorem:
Sample mean = population mean
2.3 = 2.3
The standard deviation of the sample (s) : ratio of the population standard deviation and square root of the sample size.
s = population standard deviation / √sample size
s = 2 / √100
s = 2 / 10
s = 0.2
The central limit theorem also posits that once ths sample size is large enough, the sampling of the sample mean will be approximately normal.
Hence, the distribution is approximately normal, with mean of 2.3 and standard deviation of 0.2
A geometric sequence follows a pattern with a common ratio.
Find the ratio between 3 and 9
If you multiply 3 by 3 the answer would be 9.
The common ratio is 3.
Now multiply 9 by 3 to get 27.
The answer is D. 27
<h3> Answer:</h3><h2>surface area is 227•1</h2><h2>volume is 321•7</h2>
Step-by-step explanation:
diameter is 8•5
radius is d/2
8•5/2
=4•25
surface area = 4πr^2
4×22/7×4•25×4•25
=1589•5/7
=227•1
Volume= 4/3πr^3
4/3×22/7×4•25×4•25×4•25
4/3×22/7×76•76
=321•7
