Do these pairs of values (x and y) represent two quantities that are proportional? PLEASE HELP

Yes it does. If you divide each of the y values by their corresponding x values you will see a pattern. If this pattern is the same number over and over, it is the same ratio.

Jason had three more than four times the amount of money that Jeff has. Together they have $72. How much money does each person
adelina 88 [10]

Answer:

Jason has $58.20 and Jeff has $13.80.

Step-by-step explanation:

Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.

We know that together they have $72. So, we can write the following equation:

x+y=72

We know that Jason has three <em>more</em> than four <em>times</em> the amount of money Jeff has. So:

x=3+4y

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

(3+4y)+y=72

Combine like terms:

5y+3=72

Subtract 3 from both sides:

5y=69

Divide both sides by 5:

y=69/5=\$13.80

So, Jeff has $13.80

We know that Jason has three more than four times the amount of money Jeff has.

Therefore, Jason has:

x=13.8(4)+3

Multiply and add:

x=\$58.20

So, Jason has $58.20 and Jeff has $13.80.

And we're done!

This one is hard for me so can anyone plz help me
nirvana33 [79]

Answer: The distance between a and c is 8 units

Step-by-step explanation:

You can count the number of units they are apart, but if there isn’t a grid, then do this:

If x or y values in the ordered pairs are different, subtract them from each other and find the absolute value of the difference. (It’s my own rule, so there is a better method. My explanation apples only to ordered pairs that share a x or y value, like A and C)

2-(-6) = 8, and the absolute value of 8 is 8

Or

(-6)-2 = (-8), and the absolute value of -8 is 8 (You’ll get the same answer)

An education firm measures the high school dropout rate as the percentage of 16 to 24 year olds who are not enrolled in school a
posledela

Answer:

The value of the test statistic z = -0.6606

Step-by-step explanation:

From the question we are told that

      The high dropout rate is \mu  = 6.1%  = 0.061

      The  sample size is  n = 1000

       The  number of dropouts x = 56

       The probability of having a dropout in 1000 people  \= x  = \frac{56}{1000}  =  0.056

Now setting up Test Hypothesis

 Null  H_o :  p = 0.061

 Alternative  H_a : p < 0.061        

The Test statistics is mathematically represented as

                 z = \frac{\= x - p}{\sqrt{\frac{p(1 -p)}{n} } }

substituting values

               z = \frac{0.056 - 0.061}{\sqrt{\frac{0.061(1 -0.061)}{1000} } }

               z = -0.6606
