Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km
Answer:
25% of 80 is D. 20kg
Step-by-step explanation:
50% of 80 is 40 and we know that 25% is half of 50%, so half of 40 would be 20.
So, the answer is D. 20kg

Answer: C
Step-by-step explanation:
and 
Answer:
C. (1, 1, 2)
Step-by-step explanation:
Well plugging them in one by one.
x + y - z = 0
-1 + 2 - 4 = 0
no.... no it doesn't equal 0 so it isn't the solution
-1 + 0 - 2 = 0
nope it doesn't equal 0 so it's also not the solution
1 + 1 - 2 = 0
Yes! this could equal the solution so lets keep going down the line
3x - y + z = 4
(3*1) -1 + 2 = 4
Yes! this also is correct
I could keep talking and talking but yes, (1, 1, 2) is your answer
Hope this helps! <3
The given sample's confidence interval is 4.73 ± 0.1199, or from 4.61 to 4.85
<h3>What is the z score?</h3>
The z-score is a numerical assessment of a value's connection to the mean of a set of values, expressed in terms of standards from the mean, that is used in statistics.
Given data;
Mean = 4.73
Standard deviation = 0.865
Sample size = 200
interval = 95%
Confidence interval=?
95% of samples contain the population mean (μ) within the confidence interval of 4.73 ± 0.1199.
Hence, the sample's confidence interval is 4.73 ± 0.1199, from 4.61 to 4.85
