We have to identify our evens from our odds
2,4,6,8 are evens
1,3,5,7,9 are odds.
From this we can conclude there are 4 even numbers so that is a 4/9 chance to pick an even or 44% chance.
Hope this helped!!!

Step-by-step explanation:
s = σ / √n
s = 20 / √100
s = 2
Final answer:
Using the formula for standard error, we calculate the expected error between the sample mean and the population mean in the scenario provided. The answer is 2.
Explanation:
The standard error of the mean (SEM) can be calculated using the formula SEM = sigma/ sqrt(n), where 'sigma' is the standard deviation of the population and 'n' is the sample size. In this case, sigma (σ) is 20 and the sample size (n) is 100. So, SEM = 20/sqrt(100) = 20/10 = 2.
The standard error quantifies the average amount of error between the sample mean and the population mean. Therefore, one can expect, on average, a 2 score difference between the sample mean and the population mean.

Answer:
162 Joules
Step-by-step explanation:
Remember, the equation for the kinetic energy of an object is:
where m is the mass of the object in kg (kilograms), v is the velocity of the object in m/s (meters per second), and K is the kinetic energy of the object in J (joules).
We are given that the cat's mass is 4 kg. We will use this for m. We are also given that the cat is moving at 9 m/s. This would be it's speed. We can use this for velocity, or v. Plugging in we get:
So K, or the kinetic energy, would be 162J.

(B) What is the least squares regression line
(C) According to the model in (b), for every increase of $1000 in income, the ulcer rate (per 100 population) will go down by _________ points.
Answers
Answer:
B) y = -9.98×10⁻⁵ x + 13.95
C) 0.1
Step-by-step explanation:
Using Excel, the least squares regression line, rounded to two decimal places, is y = -9.98×10⁻⁵ x + 13.95.
The slope is -9.98×10⁻⁵, so if x increases by 1000, then y changes by -9.98×10⁻² = -0.0998. Rounded to one decimal place, the ulcer rate per 100 population will go down by 0.1 points.
