Margin of error is 4.645% with 95% confidence that the mean number of hours all the residents of the city are watching news on television is 1.8 .
Data given :
A researcher surveyed 220 residents of a city about the number of hours they spend watching news on television each day. The mean of the sample was 1.8 with a standard deviation of 0.35 .
The researcher can be 95% confident that the mean number of hours all the residents of the city are watching news on television is 1.8 with what margin of error,
By formula of margin of error = [tex]M = 1.96 \times S / \sqrt{N} ,[/tex]
[tex]Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}}[/tex]
z - represents the z-value for the required confidence level .
s - represents the standard deviation of the sample .
N - represents the sample size .
Now, using the above information, compute the margin of error as -
[tex]\therefore \ Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}} \\= 1.96 \times \frac{0.35}{\sqrt{220}}[/tex]
[tex]=0.04625 (rounded \ to \ 5\ decimal\ places) \\\\ =4.625\%[/tex]
Thus, the margin of error, M, is approximately 4.625% .

Neil Down is doing some remodeling and needs to cut a triangular piece of wood such that the diagonal is 10 feet long, and the sides of the triangle are in a ratio 3:4. How long should each side be?
Answers
Answer:
6 and 8
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Given this,
(3x)² + (4x)² = 10²
9x² + 16x² = 100
25x² = 100
Divide both sides by 25
x² = 4
x = 2
Substitute this into 3x and 4x.
3x = 3 * 2 = 6
4x = 4 * 2 = 8
Thus, the answer is 6 and 8

Ronald runs 6,000 meters in 2 hours. He is thinking of running an 18 kilometers race. How much time will he take in the race if he maintains the same speed?
Answers
Answer:
6 hours
Step-by-step explanation:
speed = distance/ time
6000meters to km = 6000/1000= 6km
speed for the first race = 6/2
speed = 3km/hr
for the second race
speed = distance/time
3 = 18/time
cross multiply
3* t = 18
divide both sides by 3
t = 18/3
t = 6 hours
Answer:
Ronald will take 6 hours to complete the 18 km race if he maintains this speed.
Step-by-step explanation:
6000m in 2h = 6km in 2h
multiply by 3:
18km in 6h

The ordered pair (3, 4) is a solution for the equation:
5x + 2y = 23
2. True or false:
The ordered pair (0, 4) is a solution for the equation:
5x + 2y = 23
Answers
1) true
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23
= 15+8=23
23=23
thus, (3,4) is solution for 5x + 2y = 23
2) 5(0)+2(4) =23
= 0+8 is not 23
thus, (0,4) is not solution for 5x + 2y = 23
