Answer:
franchise fast-food restaurant located in the Northeast specializing in halfpound hamburgers, fish sandwiches, and chicken sandwiches. Soft drinks and French fries are
also available. The planning department of Bun-and-Run Inc. reports that the distribution of
daily sales for restaurants follows the normal distribution and that the population standard
deviation is $3,000. A sample of 40 showed the mean daily sales to be $20,000. Find the 95%
confidence interval for the population mean.
Answer:
Domain means all the numbers that the function passes on the x-axis. for example, when you have a straight line horizontally without stopping, your domain is ∞ since it passes every number on the x axis. The same applies to the y-axis, but now it's every number that passes the y-axis of up and down. A straight line going up and down
without stopping has a range of ∞
Answer:
-10, -11, -13, -15, -20
t≤-10
Step-by-step explanation:
Start by solving for t
-8t≥80
t≤ -10
(we flip the inequality sign because we are dividing by a negative)
Then just select all the numbers that are less than or equal to 10
-10, -11, -13, -15, -20
The equivalent inequality is what we solved for
t≤-10

It would be the last one because negative numbers start larger as they get smaller and the pattern is subtracting two
Answer:
Sheila had $300 at first
Step-by-step explanation:
Given that:
Sheila spent:
for coat = $120
Let the original money be x so,
dress for = $(2/3(x - 120 ))
Now she left with = 1/5x
Now by adding all the amounts we get the original amount x:
x = 120 + (2/3(x - 120)) + 1/5x
By simplifying:
x = 120 + 2/3x - 240/3 + 1/5 x
adding like terms:
x = 120 - 80 + 2/3*5/5x + 1/5*3/3x
x = 40 + (10+3)x/15
x = 40 + 13x/15
x - 13x/15 = 40
Taking LCM
(15x - 13x)/15 = 40
2x/15 = 40
Multiply both sides by 15/2
x = 40*15/2
x = $300
so Sheila had $300 at first
i hope it will help you!
