Answer:
The 80% confidence interval is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 23
The sample mean is 
The standard deviation is 
From the question we are told the confidence level is 80% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the margin of error is mathematically represented as
=> 
Generally 80% confidence interval is mathematically represented as
=>
Answer: There are n = a/7 pretzels into each bag.
Step-by-step explanation:
The options are missing, but ill try to explain it anyways.
Suppose that Sydney has pretzels, where a is an integer number.
If she puts the same number of pretzels into 7 bags. then we must divide an into 7 equal parts, then the amount of pretzels that go into each bag is
n = a/7

-47.25
0 is the real number for which there is no multiplicative inverse.
<u>Solution:</u>
Need to find a real number not having multiplicative inverse. Let’s first understand what is multiplicative inverse.
<em>Multiplicative inverse of a real number</em> is that number which when multiplied to the real number gives result as 1.
That is product of real number and multiplicative inverse is always 1.
Can you imagine any real number which whatever be the case, when multiplied by any number will never give result as 1.
Think about 0.
Whenever any number multiplied by 0, result is always zero. So there will never be a case when zero multiplied by any number gives result as 1.
Hence 0 is that real number for which there is no multiplicative inverse.
