Answer:
b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.
Step-by-step explanation:
Confidence interval:
Confidence level of x%
We build from a sample.
Between a and b.
Intepretation: We are x% sure that the population mean is between a and b.
In this question:
90%
45 CEO's
Between ($139,048, $154,144).
So
We are 90% sure that the mean salary of all CEO's falls within this interval.
The correct answer is:
b) We are 90% confident that the mean salary of all CEOs in the electronics industry falls in the interval $139,048 to $154,144.
Answer:
Depends
Step-by-step explanation:
In order to see which annual salary is higher, we must calculate the annual salary of B to compare to A. To do this, if B offers $18.00 an hour for 40 hours a week, that's $720 a week. Now to convert this to annual, multiply the weekly earnings by the 52 weeks in a year. Employer B offers $720 × 52 weeks = $37,440 annually. Assuming you didn't have a typo, $350,000 is $312,560 greater meaning A pays more. If you did have a typo, and meant that Employer A offered $35,000, then Employer B would pay more.

Conclusion: young people like condiments.
First, let's convert things into percentages, since the number in each age category is different. There are 143 in "Under 18", 233 in "18 to 40", 161 in "40 to 60", and 122 in "over 60".
Of the under 18s: 71 of 143 = 49.7% order three or more.
Of the 18-40s: 87 of 233 = 37.3% order three or more.
Of the 40-60s: 47 of 161 = 29.2% order three or more.
Of the 60 and ups: 28 of 122 = 23.0% order three or more.
The older you are, the less likely you are to order lots of condiments.
Answer:
The other sides of the square are
8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
Step-by-step explanation:
Square:
- The all sides of a square equal.
- The sum of four angles is 360°.
- The diagonals bisect each other.
- The length of diagonals are equal.
Distributive property:
a(b+c)= ab+ac
Commutative property:
a+b= b+a
Like terms:
Like terms are terms that have the same variables and the power of the variable also same.
Given the length of the side is
=4(2x+3)+16+8x
=4.2x+4.3+16+8x [ Apply distributive property]
=8x+12+16+8x
=(8x+8x)+(12+16) [ separating like terms]
=16x+28 [Adding like terms]
The other sides of the square are
8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
