The table below represents the total number of laps Jessica swam in the pool this summer:
Minchanka [31]

Compare the linear function given with the slope-intercept form of a line, given by,

y=mx+b

Where m is the slope and b is the y-intercept.


Comparing tells us that 10 is the slope. What does it mean?

<em>It means for </em><em>every unit increase in w (weeks)</em><em>, there is a </em><em>10 unit increase in number of laps</em><em>. </em>

This is choice 4.


ANSWER: "The number of laps Jessica increased her swim by each week"

Experimental vs. Theoretical Probability:
liubo4ka [24]
Hello Nitagomez,

To start the numbers 1 through 6 are on a number cube.
Half of them are even, 2, 4, and 6.

So it makes sense that when you roll the cube 60 times, you should have 30 even numbers. The theoretical probability is 30.

A predication of 20 is 10 less than the expected value of 30.
10 out of 30 is 33%.

The predication is off by 33%, I would argue that it is not a very good prediction.

I hope this helps, Good luck!

Please help! I'll give out the brainiest!
Oxana [17]
-5n-10>/20
Add 10
-5n>/30
On both sides, divide by 5 on (the coefficient of x)
-n>/6
Therefore n>/-6, so D is correct
