Answer:
Odd integers are always one more that an even integer:
1st: 2n+1
2nd: 2n+3
Step-by-step explanation:
14n+7 = 10n+15
4n = 8
n = 2
------------
1st: 2n+1 = 5
2nd: 2n+3 = 7
7x=5*(x+2)
7x=5x+10
7x-5x=10
2x=10
x=5

Answer: A. Approximately 0.017 pounds
Step-by-step explanation:
Formula to find the margin of error :
, where z* = critical value for confidence interval , s= standard deviation , n= sample size.
As per given , we have
s= 0.15 pound
n= 300
Critical value for 95% confidence = 1.96
Then, Margin of error for 9%% confidence interval will be :
Hence, they can expect a margin error of 0.017 pound (approximately.)
Thus , the correct answer is A. Approximately 0.017 pounds
I'm in middle school (8th grade) and this is relatively easy, for me, so...
if each batch of muffins can make 6 muffins, and she makes 2.5 batches of blueberry muffins which will make 15 muffins, she will need to make 7.5 batches of banana muffins to equal 45 muffins and 45 + 15 = 60 muffins.
Here is the math part of it......
1 batch = 6 muffins
She makes 2.5 batches, 2.5 * 6 = 15 muffins
x*6 = 45
divide 6 by both sides to get this
x = 7.5
She needs to make 7.5 batches in order to make the rest of the 60 muffins
