You should look for outliers. If there is an outlier then you should use median because if you use mean the data would be skewed.
Answer:
the ratio of the adjacent side to the hypotenuse is a function of the angle c, so we can write the symbol as cos(c) = value. 90
Step-by-step explanation: You can also see that 40 + 41 + 9 = 90. hope this helps
<span>W = event where white marble is drawn
B = event where black marble is drawn
The two events W and B are independent. This is because the marble taken out on the first draw is put back into the bag. Since W and B are independent, we can use this rule
P(W and B) = P(w)*P(B)
Use the rule to get
P(W and B) = P(W)*P(B)
P(W and B) = (1/2)*(1/4)
P(W and B) = (1*1)/(2*4)
P(W and B) = 1/8
1/8 is equivalent to 0.125. Use long division or a calculator
0.125 = 12.5% </span>
Answer:
The will play the song at the same time by 4:12 pm
Step-by-step explanation:
here, we want to know the time both radio station will play the song after 3pm.
Mathematically to get this, we shall need to find the lcm of both 18 and 24. LCM stands for the lowest common multiple of both.
The lowest common multiple of both is 72.
This means that after 72 minutes, they will both play the song
So the time then would be;
72 + 3 = 4 : 12 pm
Alright, lets get started.
Suppose previously I was selling product per week = x
As per question, I have decreased my average number of product by 15 %
Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x
So, the new average product = x - 0.15 x = 0.85 x
As per given question, the new average product = 21.25
0.85 x = 21.25
Dividing by 0.85 in both sides
0.85 x / 0.85 = 21.25 / 0.85
x = 25
Hence it means, 25 products were selling previuosly. : Answer
Hope it will work :)
