30°
Here's why:
Using the well-known Pythagorian theorem we can reckon how long the hypotenuse is:
c^2=6^2+36*3 -> c=12
Knowing that sin(a)=a/c=6/12=0.5 the measure of the angle in degrees is 30°
Hope could help :)
Total units would be: 4+7 = 11
value of 1 unit = 44/11 = 4
Ratio would be: 4(4) & 7(4) = 16 & 28
Answer:
The score is 
Step-by-step explanation:
From the question we are told that
The population mean is 
The standard deviation is 
From the question we are told that the score follow a normal distribution
i.e 
The proportion of score in the top 10% is mathematically

Where x is the minimum score required to be in the top 10%
Now the 
So

So

So the critical value of 0.10 from the normal distribution table is 
So


Answer:
4 strawberries and 6 blueberries
Step-by-step explanation:
2c+3d=900
C=x
D=350-x
2x+3 (350-x)=900
Solve for x to get number of children
attended the fair that day
2x+1050-3x=900
2x-3x=900-1050
-1 x=-150
x=150 children
350-150=200 adult
