Answer:
b) 9 in
Step-by-step explanation:
To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.
If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median
Ascending order:
6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16
total = 10. so even number
Median = average of 5th term and 6th term
=(9+9)/2
= 18/2
= 9
Answer:15
Step-by-step explanation:
She spent 25% and had $99 left.
$99 is 75% of the remaining money.
Divide to find the total remaining
99 / 0.75 = $132
Now she put 80% of her total earnings in the bank, this means the remaining amount is 20%.
Divide the remaining amount by 20%:
132 / 0.20 = $660
She earned $660 total.
Hey there!
To start, none of these triangles appear to have a given height, only a given angle. Another thing to notice is that neither of these triangles are right. This means that you would need to use the function of sine to calculate the area of the triangle.
First, you know that the sine triangle area formula is:
A= 1/2*side*side*sin(given angle)
Knowing that the area of ΔABC is 30, the sides given are x and y, and the angle is 70, you can set up this equation:
1/2*xy*sin(70)=30
Now, solve for xy:
2(1/2*xy*sin(70)=30)
=xy*sin(70)=60
=xy=60/(sin(70))
Now, use the same formula to solve for the area of ΔPQR knowing that xy=60/(sin(70)).
1/2*60/(sin(70))*sin(110)
=30 cm squared
Therefore, the correct answer would be 30.
Hope this helps!
