<h3>
Answer: 5</h3>
The coefficient is the term just to the left of the variable. So for the term 5y, the number to the left of y is 5.
extra info: 5y is the same as 5*y or "5 times y", where y is a placeholder for some unknown number.

I took the test
Answer: $35.35
Step-by-step explanation:
Facts
3 items
item 1: 8.95
item 2: 11.49
item 3: 12.75
6.5% sales tax
Step 1: Find the total cost of the items ,before tax
8.95+11.49+12.75= 33.19
Step 2: Apply the sales tax
6.5% of 33.19 = 2.15735 --> approximatley $2.16
Step 3: Add the sales tax amount to the total cost of the items to find the final total cost.
$33.19+$2.16= $35.35
Hence the answer is B
Hope this helps !! :)) And brainliest would be appreciated
If inspection department wants to estimate the mean amount with 95% confidence level with standard deviation 0.05 then it needed a sample size of 97.
Given 95% confidence level, standard deviation=0.05.
We know that margin of error is the range of values below and above the sample statistic in a confidence interval.
We assume that the values follow normal distribution. Normal distribution is a probability that is symmetric about the mean showing the data near the mean are more frequent in occurence than data far from mean.
We know that margin of error for a confidence interval is given by:
Me=
α=1-0.95=0.05
α/2=0.025
z with α/2=1.96 (using normal distribution table)
Solving for n using formula of margin of error.

n=
=96.4
By rounding off we will get 97.
Hence the sample size required will be 97.
