Answer:
A stem and leaf diagram displays numerical data.The stem and leaf diagram is ordered if the data is in numerical order.
Step-by-step explanation:
Answer:
- x + y ≤ 20,000
- y ≤ 5,000
- x ≥ 2y
Step-by-step explanation:
Given:
Total amount = $20,000
Assume
Government bonds = x
Municipal bonds = y
Computation:
1. Invest total money
x + y ≤ 20,000
2. invest no more than $5,000 into municipal bonds
y ≤ 5,000
3. at least twice as much into government bonds.
x ≥ 2y
Domain means the set of x values. So the domain would be 1,4,6
Answer:
a. The probability that 359 or more of 1487 adults sleepwalked is zero (0).
b. Yes, it's significantly higher than the 21.6% of people who sleepwalked.
c. The result suggests 321 adults.
Step-by-step explanation:
a. The assumed 359 sleepwalked adults exceed the 21.6% correct rate. 359 sleepwalked adults give 24.1%.
b. Yes, it is significantly high because it's 24.1% instead of correctly assumed 21.6%.
c. 21.6% sleepwalked adults give 321.2 people. Hence, people can only be in whole of numbers. Therefore, it is 321 adults.
