The vol. of a cube of side length s is V=s^3.

So, if the side length is 5a+4b, then the volume of the cube is

V(a, b) = (5a+4b)^3.  This could, of course, be expanded, using the binomial theorem, but there's no point in doing so.

What is the y intercept?​
timama [110]

Hey there!

We can see that the y-intercept is 6, or (0, 6), because when x is equal to 0, that is the y-intercept.

A driving school wants to find out which of its two instructors is more effective at preparing students to pass the state’s driv
jonny [76]

Answer:

Yes, there is evidence to support that claim that instructor 1 is more effective than instructor 2

Step-by-step explanation:

We can conduct a hypothesis test for the difference of 2 proportions.  If there is no difference in instructor quality, then the difference in proportions will be zero.  That makes the null hypothesis

H0:  p1 - p2 = 0

The question is asking whether instructor 1 is more effective, so if he is, his proportion will be larger than instructor 2, so the difference would result in a positive number.  This makes the alternate hypothesis

Ha:  p1 - p2 > 0

This is a right tailed test (the > or < sign always point to the critical region like an arrowhead)

We will use a significance level of 95% to conduct our test.  This makes the critical values for our test statistic: z > 1.645.  

If our test statistic falls in this region, we will reject the null hypothesis.

Kelly answered 3 items on a test incorrectly. This was 6% of the items. How many items were on the test?
alukav5142 [94]

Answer:

50

Step-by-step explanation:

6/100=3/y

Let y be the total number of items on the test

[cross multiply]

6×y =3×100

6y = 300

divide both sides by 6

y = 50
