Answer:
715
Step-by-step explanation:
All you do is 465 + 250
465 + 250 is 715
Answer: (B)
Explanation: If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.
But a more intuitive way is to determine what happens during each transformation.
A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.
Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.
What happens to the graph?
Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).
What about the y = |x| + h graph?
Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.
So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.
.Answer:
D. 12.3
Step-by-step explanation:
Arrange the data in increasing order
3.4, 10.8, 16.7, 23.1, 31.5
⇒This is an odd set of numbers, to find the interquartile range you include the median in both quartiles.
Locate the median/center value
3.4, 10.8, 16.7, 23.1, 31.5
Find lower half and find the median
lower half values⇒3.4, 10.8, 16.7
Median=Q1=10.8
Find the upper half and find
upper half= 16.7,23.1, 31.5
median= 16.7,23.1,31.5
Q3=23.1
Interquartile range=Q3-Q1
23.1-10.8=12.3
