Answer:
Coin 1 = quarter
Coin 2 = dine
Coin 3 = penny
Step-by-step explanation:
First change the mixed fraction to improper fraction, and then find common denominators.
5 1/2 = 11/2
4/9(2/2) = 8/18
11/2(9/9) = 99/18
-------------------------------------------------------------------------------------------------------------------
Next, subtract
99/18 - 8/18 = 91/18
91/18 = 5.05
-------------------------------------------------------------------------------------------------------------------
As you are finding the best estimate, 5.05 is closest to 5, which makes your answer D)

Answer:
<h3>5cm</h3>
Step-by-step explanation:
From the questions;
1cm represents 200km on the map
If the length of distance between the cities is 1000km, the distnce on the map will be say x;
x cm = 1000 km
Divide both equations;
1/x = 200/1000
Cross multiply;
200x = 1 * 1000
200x = 1000
x = 1000/2000
x = 5cm
Hence the length on the map that represents the distance
between the two cities is 5cm
Answer:
The estimated mean number of rockets hits in the region is 533.
Step-by-step explanation:
We are given the following information,
Number of rocket hits | Observed number of regions
0 | 228
1 | 214
2 | 94
3 | 32
4 | 7
5 | 0
6 | 0
7 | 1
We are asked to estimate the mean number of rocket hits in the region.
The mean or expected value is given by
Therefore, the mean number of rockets hits in the region is 533.
