There are 10 spaces then the first space will be <span><span>(3,1</span></span>), the second one cannot be the same as the first one so it will have to be (2,1).
So it will come down to <span><span>3×2^9</span></span>
Answer: n=1.8
Step-by-step explanation:
6n+14=25
-14 on both sides
25-14=11
6n=11
divide 6 on both sides
n=1.83333..
Answer:
The new level is inches.
Step-by-step explanation:
Given: At the start of summer, Little Crater Lake is inches below normal. By the end of summer, it had decreased an additional inches.
To find: What is it's new level?
Solution:
We have,
At the start of summer, Little Crater Lake is inches below normal.
So, at the start of the summer, Little Crater Lake is inches below normal.
By the end of summer, it had decreased an additional inches.
So, by the end of summer, it had decreased an additional inches.
Now, the new level is inches.
Hence, the new level is inches.

Answer:
The answer is below
Step-by-step explanation:
When you fill your coffee at a gas station, you're supposed to get 8 ounces of coffee with a standard deviation of .7 ounces. A random sample of 50 "8 ounce" coffees is collected and measured and the mean was found to be 7.8 ounces. a) Find a 90% confidence interval. b) Interpret the confidence interval in the context.
Solution:
The confidence = 90% = 0.9, mean (μ) = 7.8 ounces, standard deviation (σ) = 0.7 ounces, sample size (n) = 50
α = 1 - C = 1 - 0.9 = 0.1
α/2 = 0.1 / 2 = 0.05
The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65
The margin of error (E) is given by:
The confidence interval = μ ± E = 7.8 ± 0.16 = (7.64, 7.96)
b) This means that we are 90% confident that any selected coffee has a weight between 7.64 ounce to 7,96 ounce
