Answer:sin240
Step-by-step explanation:
Sin300=(-√3)/2
Sin240=(-√3)/2
So sin300 is equivalent to sin240
Answer:
Find the median of this data
21+23+60+60+50+54+54+59+26+15+43+15=480/ 12 = 40
Now the median should be 50 so take 50 - 40 = 10
The missing number from the data is 10
84 to 62. You have to subtract 146-84 to get the number of girls from the class.
<span>5x-102=13
Add 102 to both sides
5x=115
Divide 5 on both sides
Final Answer: x=23</span>
Answer:
first, we put them in order
78,[80],83,(85),86,[87],90
Q1 = 80
Q2 (median) = 85
Q3 = 87
Interquartile range (IQR) = Q3 - Q1 = 87 - 80 = 7 <==
Hope this helps!
