Circle One:

No

Explain:

The chart shows that teenagers get roughly between 7 - 8 and 1/2 hours of sleep every night. It shows that no teenagers get 9 and 9 and 1/2 hours of sleep. This is why their data does not support the delay to starting time.

Consider f(x)=-(x+7)^2+4. Which of the following are true for f(x)?Check all that apply.
lisabon 2012 [21]

Answer:

A, D, F

Step-by-step explanation:

A. True, because f(x)=-(x+7)^2+4 represents quadratic function (the greatest power of x is 2)

B. False, because this function is quadratic, so cannot be linear

C. False. The vertex of the parabola is at point (-7,4) (see diagram)

D. True. The axes of symmetry is the line x=-7 that passes through the vertex.

E. False. The y-intercept is at point x=0 and y=-(0+7)^2+4=-49+4=-45.

F. True. The graph has the maximum at vertex, where y_{max}=4.

G. False. The graph of the parabola intersects the x-axis at two points (-9,0) and (-5,0), so x=-9 and x=-5 are two real solutions of the equation f(x)=0.

What are the steps to find the lower and upper quartiles of a data set? 1. Order the values. 2. Find the median. 3. Find the low
Yuri [45]
The steps to finding the upper and lower quartiles are given in the first choice.

1.  Order the data from least to greatest. If you don't do this, the data is random.

2.  Find the median - you will do this so that you can find the midpoint of the data set (half of of the data is smaller and half of the data is larger).

3.  Find the lower quartile - this is the half of the lower half of numbers; think of it as breaking the lower half of the data into 2 sections. 

4.  Find the upper quartile - this is the half of the greater half of numbers; this will break the upper half of the data into 2 sections.
