7.72 convert the nickels and dimes into pennies, add that to the other number of pennies and divide that by 100
This is a quadratic in the form of ax squared +bx +c
So
a = 3
b = -5
c = 2
Hope this helps!
Student's error is –5 < x.
Solution:
Step 1: Given inequality
31 < –5x + 6
Step 2: Subtract 6 from both sides of the inequality.
31 – 6 < –5x + 6 – 6
25 < –5x
Step 3: Multiply both sides by –1 to reverse the inequality.
25 × (–1) > –5x × (–1)
–25 > 5x
Step 4: Divide by 5 on both sides.
–5 > x
The correct answer is –5 > x.
Student's error is –5 < x.
Answer:
The value of the test statistic is 2.8.
Step-by-step explanation:
The test statistic is:
In which X is the sample mean, 
is the value expected value for the population mean, 
is the standard deviation and n is the size of the sample.
Sales at a fast-food restaurant average $6,000 per day
This means that 
Sample of 49
This means that 
The sample showed average daily sales of $6,400.
This means that 
Population standard deviation is about $1,000.
This means that 
The value of the test statistic is
The value of the test statistic is 2.8.
