Answer:
- see the attachment for a graph
- domain: all real numbers
- range: -6 and y>-5
Step-by-step explanation:
The graph below was created by a graphing utility.
It shows no horizontal gaps: f(x) is defined for all values of x, so the domain is all real numbers.
It shows a vertical gap between y=-6 and y>-5. So, the range is in two parts:
{-6} ∪ {y > -5}
Answer:
I would say 98% chance

if this helps you pls give me brainliest
Answer:
First, The experimental probability of spinning a 4 is 200 or 18.5%.
18.5 in fraction form is 37/2.
Step-by-step explanation:
185/10 = 37/2 = 18 and 1/2
Shouldn't it be the same volume, 38.4?
Answer:
There is a strong positive correlation coefficient for the relationship between data plan size 'x' and number of text messages sent 'y'
Step-by-step explanation:
In statistics, the correlation coefficient is attributed to a symbol R. Correlation Coefficient value spread over a range from -1 to +1. It shows the depth of relationship between the movement which is relative of two existing variables
From the given question;
We have the study of the relationship between the data plan size and the number of text messages sent in the U.S.
When R value is at 0 ; it illustrates and pinpoint the fact that there is no relationship between these two variables under study.
However; the R value near to +1 and -1 definitely shows the strength of the positive and negative correlation of the two variables under study.
Given that :
R = +0.97 ; we can see from above explanation that this is showing and telling us that there is a strong positive correlation coefficient for the relationship between data plan size 'x' and number of text messages sent 'y'.
Conclusion: we conclude that the large data size corresponds to the large number of text messages and the small data size corresponds to the small number of text messages.
