Complete question :
The spinner shown is spun once. Determine the probability of each event. Express each answer as a fraction, a decimal, and a percent. P(C)
Answer:
1 / 8; 0.125 ; 12.5%
Step-by-step explanation:
From the spinner :
The number of partitions or faces on the spinner is 8 ;
The number of occurences of c on the spinner is 1
The probability of obtaining c written as P(c) :
Probability = required outcome = number of c on spinner / total possible outcomes, total number of faces in spinner = 8
P(c) = 1 / 8
As decimal :
1/8 = 0.125
As a percentage :
0.125 * 100% = 12.5%
Answer:
10b/9
Step-by-step explanation:
multiply the quotient of b and 10 by 9
Answer:
x = -18
y = 4
Step-by-step explanation:
x + y = 4
2x + 3y = 30
You can do any math operation to each side of the equal sign as long as you do the same operation to both sides.
change x + y = 4 to x = 4 - y
Now substitute (4 - y) into the second equation, in place of x.
2(4-y) + 3y = 30
multiply the 2(4-y) part:
8 -2y + 3y = 30
simplify:
8 + y = 30
subtract 8 from each side:
y = 22
now substitute the value of y back into the first equation to solve for x:
x + 22 = 4
subtract 22 from both sides:
x = -18
Check:
x + y = 4
22 -18 = 4
4 = 4 (this checks)
2(-18) + 3(22) = 30
-36 + 66 = 30
30 =30 (this checks also)
PS: you could have solved for y first if you had wanted to. The results would be the same.
Answer:
That`s kind of hard to understand, but I think it`s -10
