Hi there,
There are 16 members in a math club such as 2 girls and 14 boys in a math club.
The ratio would be:
1:7
Divide both terms by 2.
2 ÷ 2 = 1
14 ÷ 2 = 7
Therefore:
2 : 14 = 1 : 7
Answer:
5383 4983
i dont know
Step-by-step explanation:
Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° = 
, sin30° = 
, then
cos30° = 
= 
= ( cross- multiply )
2x = 20
× = 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° = 
= 
= ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10

Answer:
300-400
Step-by-step explanation:
The first step is finding the total of the data we have. So, we take 5 + 10 + 15 + 20 + 25 + 15 + 10 which equals 80.
The median is the middle point of all the data. If it's an odd number, you can calculate the median with the equation (n+1) / 2, plugging in the total amount of data for n.
When it's an even number though, there is no one middle point since the data splits evenly in 2, so we have to use 2 equations: n/2 & (n/2) + 1. Then, we find the average of those two data points. (Although, you don't have to do that for this particular question).
When we plug 80 in for n in both of these equations, we get 40 and 41.
To where this is in the question, we have to count up from the bottom of the chart. 1-5 is below 100, 6-15 is 100-200, 16-30 is 200-300, and 31-50 is 300-400.
Since 40 and 41 are between 31 and 50, the answer is 300-400.
Hope this helps! :)
