You use inclined planes by putting an object on something and push it down like a ramp.
I found the picture of the bowl.
AB is the diameter of the sphere.
So the radius is 20in / 2 = 10 in
And the volume of water is half the volume of the sphere.
=> V of water = (1/2)* (4/3) π (r^3)
Also, this problems asks to use 22/7 as approximation of π.
=> V of water = (1/2) (4/3) (22/7) (10in)^3 = 2,095 in^3
Answer: (1/2)(4/3)(22/7)(10in)^3 = 2,095 in^3
Hi!
If you want to show these are congruent, you make a single line through each of the sides. Just do this for both of the triangles.
See the screenshot for example
Hope this helps! :0)
Answer:The correct answer is A
Step-by-step explanation: just trust me
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.
