Answer:
Atleast 93.75% of data lies between 15 and 31.
Step-by-step explanation:
We are given the following in the question:
Mean = 23
Standard deviation = 2
We have to find he data lying between 15 and 31.
Thus, we have to find the data lying within 4 standard deviation from the mean.
Chebyshev's Theorem:
- According to this theorem atleast
percent of data lies within k standard deviation of mean. - For k = 4.
Thus, atleast 93.75% of data lies between 15 and 31.
100,000,000+3,000,000+700,000+20,000+7,000+400+90+5
I think the equation would be either a perimeter equation or a volume equation.
P=a+b+c (For a two-dimensional figure)
V=1/3 Bh (For a three-dimensional figure)
U should get the app "photomath" it will help out alot!!!
Answer:
B.
Step-by-step explanation:
The X-values are between -1 and 5. --> -1 ≤ x ≤ 5
The Y-values are between -4 and 2. --> -4 ≤ Y ≤ 2
Looking at the answer which matches up with these, you get B.
