Answer:
T = 47.1875°C
Step-by-step explanation:
Given:
Surrounding temp, Ts = 100°C
Initial Temperature ,T0= 20°C
Increase in temperature = 15°C
Final temperature, T = 20 + 15 = 35°C
Time, t = 9 seconds
Let's take Newton's law of cooling:
We'll solve for k
Divide both sides by -5
Let's now find the temperature of the ball after 18 seconds in boiling water.
Use the Newton's equation again:
T = 47.1875°C
Temperature of the ball after 18 seconds in boiling water is 47.1875°C
The standard error for the distribution of sampling proportions will be 0.0686.
<h3>What is standard error for the distribution of sampling proportions?</h3>In mathematics, the difference between a data set and the populace's true average is known as primary data deviation from the mean.
According to the National Postsecondary Student Aid Study conducted by the U.S.
Department of Education in 2008, 62% of graduates from public universities had student loans.
We randomly select 50 students at a time.
Then the standard error for the distribution of sampling proportions will be
