Which stem-and-leaf plot represents the data 80, 81, 91, 92, 66, 55, 54, 30, 55, 79, 78?
const2013 [10]
Convert the given data into ascending order.
30,54,55,55,66,78,79,80,81,91,92
Here the minimum value is 30 and maximum is 92.
Total counts=11
Now plot the data.
Stem | Leaf
3 | 0
5 | 4 5 5
6 | 6
7 | 8 9
8 | 0 1
9 | 1 2
This is the required stem leaf plot.
Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The sample size is n = 175
The population proportion is p = 0.45
Generally the mean of the sampling distribution is
Generally the standard deviation is mathematically represented as
=>
=>
Generally the probability of that the sample proportion of orange candies will be between 0.35 and 0.55 is
=>
Generally
So
=>
From the z-table
and
So
=>
Total number of people on boat=30
Half as many children as adults means:
Number of children = 1/2 ( Adults)
Let number of adults= A
Then equation is:
So number of children= 1/2 x 20 =10
Answer: 10 Children
Express x from the secondequation: x=3+y.
Then substitude it in first equation:
4(3+y)+2y=12,
4·3+4y+2y=12,
12+6y=12,
6y=12-12,
6y=0,
y=0 and x=3+0=3
Answer: (3,0)
