Answer:
Step-by-step explanation:
<u>Use properties of rhombus:</u>
- diagonals are perpendicular
- diagonals are angle bisectors
- opposite angles are equal
<u>The angle measures are:</u>
- m∠2 = 90°
- m∠3 = 70°
- m∠1 = m∠4 = 90° - 70° = 20°

adding 5 each time
Answer:
Colin's mean score = 17.10
The new mean is 18.00
Step-by-step explanation:
Given scores: 31, 10, 26, 16, 28, 31, 9, 11, 8, 1
number of terms: 10
mean is calculated by given formula = sum of all the data set/ number of terms in the data set.
mean for the 10 scores = (31+ 10+ 26+ 16+ 28+ 31+ 9+ 11+ 8+ 1 )/10
= 171/10 = 17.1
Colin's mean score = 17.10
____________________________________________
runs scored by Colin in 11th match = 27
number of terms: 11
new mean = new sum /number of terms
new mean = (old sum score + 27)/11 = (171+27)/11
new mean = 198/11 = 18
The new mean is 18.00
The range is the highest number minus the lowest number
98 - 13 = 85 <==
