Researchers make a one-sample z interval to estimate the proportion of adults who would say they learned
something new in the past month. Previous studies have suggested that about 40% would answer "yes" to this
question. The researchers plan on using a confidence level of 95%, and they want the margin of error to be no
more than 25%.

Andrew is starting his own snow plowing business. Andrew has calculated that he needs to earn $500 per week to support his family. If he knows he will only be able to work 50 hours per week, what is the minimum amount of dollars per hour that he will need to charge his customers?
Answer:Ten dollars per hour
Step-by-step explanation:
50 hour =500 dollars
1 hour = ?
Using the criss cross method we multiply one hour by five hundred dollars and divide by fifty dollars.
?=(1 hour×500 dollars)/50 hour
?= 500 dollars/50
?=10 dollars per hour
Answer:
$10
Step-by-step explanation:
$500/50= 10
He needs to earn $10 an hour x the 50 hours = $500

Im going with B hope this helps
Step-by-step explanation:
Write an equation for (-1,-2),(-3,-4)
Answer:
y=x+1
Step-by-step explanation:
First find the slope by subtracting the y values from both points and dividing it by the subtraction of the x values from both points:
-4--2/ -3--1= -2/-2= 1
so the slope is 1
Now find the y-intercept by plugging in the x and y from one of the points into the equation y=x+b
-3=-4+b
1=b
now plug the slope and y intercept in:
y=x+1
hope this helps :D

Pls help me with my homework
what is $420 with a 6% tax
=============================================================
Explanation:
There are two approaches.
The slightly longer approach will have us take 6% of 420 to get 0.06*420 = 25.20
So 25.20 is the amount of tax you pay on top of the original $420. The total bill is 420+25.20 = 445.20 dollars
--------------
The shortcut is to multiply 420 by 1.06 to get 420*1.06 = 445.20
The 1.06 multiplier indicates an increase of 6%
We can think of it it as 1.06 = 1 + 0.06 = 100% + 6%

y=xe^x how do you find the domain of the following function
9514 1404 393
Answer:
all real numbers
Step-by-step explanation:
Basically, you look for any values of x for which the function is not defined. There are none. So, the domain is "all real numbers."
__
The function is the product of a polynomial (x) and an exponential function (e^x). Each of those kinds of functions has a domain of "all real numbers". Multiplication is also defined for all real numbers, so there is nothing about this product that would restrict the domain.
Which of the following shows the correct evaluation for the exponential expression 1 over 5 to the power of 3?
1 over 5 times 3 equals 3 over 5
1 over 5 times 1 over 5 times 1 over 5 equals 1 over 125
1 over 5 plus 3 equals 3 and 1 over 5
1 over 5 divided by 3 equals 1 over 15

Step-by-step explanation:
Caitlin purchased a prepaid phone card for $20. Long distance calls cost 7 cents a minute using this card. Catin used her card only once to make a long
distance all the remaining credit on her card is $168. how many minutes did her call last?
Correct question is;
Caitlin purchased a prepaid phone card for $20. Long distance calls cost 7 cents a minute using this card. Catin used her card only once to make a long distance all the remaining credit on her card is $16.8. how many minutes did her call last?
Answer:
45 minutes 43 seconds
Step-by-step explanation:
We are told that she purchase the prepaid phone card for $20.
Now she has $16.8 after making the call.
Therefore;
Amount spent on the call = 20 - 16.8 = $3.2
We are told that the long distance call costs 7 cents per minute. Which is $0.07 per minutes
Thus, time spent = $3.2/$0.07 = 45.714 minutes or 45 minutes 43 seconds
4x + 3y = -26
x-3y =-14
Answer:
y = 8 x= -16
Step-by-step explanation:
4x+26x = -6y =14
30x = 14
-6y = 14 x = 14- 30
y+= 14-6
y = 8 x= -16

What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation?
What number would you multiply the second equation by in order to eliminate the y-terms when adding to the first equation?
Answer:
To eliminate the x-terms, multiply the second equation by 2.
To eliminate the y-terms, multiply the second equation by 3.
Step-by-step explanation:
The first step of solving by elimination requires that you eliminate either the x-terms or y-terms by making the two terms have the same coefficient, but opposite signs.
So, if you wanted to eliminate the x-terms, you could multiply the second equation so that its x term has the same coefficient as the x-term in the first equation, but with opposite signs. The x-term in the first equation is 4x. The x-term in the second equation is -2x. They already have opposite signs, so we just need the -2x to become -4x. -4x divided by -2x is 2, thus you would multiply the second equation by 2.
If you wanted to eliminate the y-terms, the process is the same. The y-term in the first equation is -9y and the y-term in the second equation is 3y. Again, they already have opposite signs, we just need 3y to become 9y. 9y divided by 3y is 3, thus you would multiply the second equation by 3.
Answer:
to eliminate x, u would multiply second equation by 2
to eliminate y, u would multiply second equation by 3
