Answer:
A. It is symmetric and has no gaps.
Step-by-step explanation:
Given
See attachment for dot plot
Required
Select the true statement
From the attached plot, we can see that
- The plot is bell shaped (by tracing the number of dots on each dataset)
- There is no gap between each dataset (from 4 to 7)
Since (1) all bell shaped distribution are symmetric and (2) there is no gap between the dataset, <em>then (a) is correct.</em>
Answer:
raju is 20 years old while the father is 40 years old
Step-by-step explanation:
present : lets assume raju is x years old so the father will be 2x
after 10 yrs raju will be x+10 yrs while the father will be 2x+10 yrs
therefore :
(x+10)+(2x+10)=80
liketerms together
x+2x+10+10=80
3x+20=80
3x=80-20
3x=60
simplify
x=20 so raju is 20 years old now and the father since he is twice the age of his son he is 40 years old
It is equal to 21/2 which is a rational number
Answer:
0.67 feet
Step-by-step explanation:
This question can be interpreted as find the 11th term of a geometry progression where a = 6.25 and r = 80%
So, we have:
In this case:
So, we have:
Hence, the height of rebound at the 11th time is approximately 0.67
Answer:
No, doubling the base and height would actually quadruple the area,
Step-by-step explanation:
With the original measurements of b = 3 ft and h = 5 ft,
<em>b x h = A</em>
<em>(3) x (5) = </em><em>15 ft</em>
So lets say we <em>doubled</em> the factors:
<em>(2)(3) x (2)(5) = A</em>
We would end up with 60 feet, four times that of 15.
<em>(6) x (10) = </em><em>60 ft</em>
