answer is A. cosine
Step-by-step explanation:
Answer:
25 times
Step-by-step explanation:
From the question:
Number of :
Yellow = 2
Red = 3
Blue = 5
P(blue) = required outcome / Total possible outcomes = 5/ 10 = 1/2
If marble is drawn with replacement :
Number of times a blue marble is drawn from 50 trials :
P(blue marble) * 50
1/2 * 50
= 25 times
Answer:
Step-by-step explanation:
Hey there!
In order to solve this equation, you need to first simplify and take the absolute value:
x+2+x+2-x+5
Now you need to simplify
x+9
So, the rewritten form of the equation is x+9
Step-by-step explanation:
It is in the form of a² - b²
so it's correct product is
64x² - 16
