40 tiles
Assuming the vowels and non-vowels are equal to the five picked, there would be 40 tiles that are vowels.
You have picked five different letters. 5% or 1/20 of 100. If two of those five were vowels, then if you consistently pick 2/5 vowels every time, a predicted 40 tiles will be vowels, 60 would not.
Your answer is C.The relation passed the vertical line test.
Answer:
Height: 6.7 Length: 22
Step-by-step explanation:
Use Soh (sin(angle)=) Cah (cos(angle)=) Toa (tan(angle)=)
Height:
You'd use sin so the equation is sin17=x/23 which is equal to (rounded) 6.7
Length:
You'd use cos so the equation is cos17=y/23 which is equal to (rounded) 22
*You always need to use a calculator when using sin, cos, and tan*
*SohCahToa is an easy way to remember the equations!*
Hope this helped!
Answer:
The answer to this system is (0.75, 2.75)
Step-by-step explanation:
To solve a systems of equations graphically, all you need to do is graph the equations and find where they intersect.
It would be 25% because 4 names will be drawn and 25*4 is 100%.
