Answer:
I believe the correct answer is A.
Step-by-step explanation:
If we were to make a list of the amount of money in Jobie's piggy bank at the end of each month (including the amount she started with), the first number in the list would have to be $325, which means that a1 is equal to 325. So we can rule out choices C and D.
When reading the problem, notice that it states that she <u><em>ADDS</em></u> $10 a month. This means that the model will have to be an addition based function. This rules out answer choice B, leaving us with choice A as the the answer.
I hope this helps!
Answer:
12 x 40 = 480 feet per minute.
480 x 60 = 28800 feet per hour.
28800/5280 = 5.45 miles per hour.
Hope that helps.Thank you!!!
Distributive property is being used to get 8x-4x+6.
Answer:
2.083 < µ1 - µ2 < 5.917
Step-by-step explanation:
We will need to construct a 90% confidence interval for the difference of 2 means where the populations are normally distributed, and their variances are equal.
The calculations of the sample means and standard deviations are done for us.
Sample 1: Catalyst 1
n = 12, x = 85, s = 4
Sample 2: Catalyst 2
n = 10, x = 81, s = 5
See attached photo for the construction of the confidence interval...
