Answer:
x=3
Step-by-step explanation:
3x + x + x + x − 3 − 2 = 7 + x + x
Combine like terms
6x -5 = 7+2x
Subtract 2x from each side
6x-2x -5 = 7+2x-2x
4x-5 =7
Add 5 to each side
4x-5+5 = 7+5
4x =12
Divide by 4
4x/4 = 12/4
x = 3
Answer:
131°
Step-by-step explanation:
The central angle in the triangle is 180 - 41 - 41 = 98
which makes the intercepted arc 98
the big arc below is then 360 - 98 = 262
x is an inscribed angle which is half of the arc
1/2(262) = 131
Answer:
The require expected value of x is 
Step-by-step explanation:
Consider the provided information.
Mike will play a game in which he will toss a penny, a nickel, and a dime at the same time.
The probability of head is 
He will be awarded 3 points for each coin that lands with heads faceup.
Let the random variable x represent the total number of points awarded on any toss of the coins.
Thus the expected value is:



Hence, the require expected value of x is
