Answer:
Step-by-step explanation:
First count the number of sides. There are 6 sides.
Now use the formula
(n - 2) * 180 To determine the total of all 6 angles.
(6 -2) * 180 =
4 * 180 = 720
Is that a 9 in x + 9 [lower left]? I'll assume so. Edited to show it was a 4.
x + 4 + 120 + x + 50 + 140 + 112 + x = 720 Combine
3x + 4 + 120 + 50 + 140 + 112 = 720
3x + 426 = 720 Subtract 431 from both sides
3x = 720 - 426 Combine
3x = 294 Divide by 3
x = 294/3
x = 98
Answer:
19
Step-by-step explanation:
6×(6+14) = 5×(5+z)
120 = 25 + 5z
95 = 5z
z = 19

My apologies if my answer is wrong :)
Answer: option 1 is the correct answer
Step-by-step explanation:
Number of times for which the die was rolled is 360. It means that our sample size, n is 360.
The probability of rolling a 5 or a 6 is 1/3. It means that probability of success,p = 1/3. The probability of failure,q is
1 - probability of success. It becomes
1 - 1/3 = 2/3
The formula for standard deviation is expressed as
√npq. Therefore
Standard deviation = √360 × 1/3 × 2/3
= √80 = 8.9443
Standard deviation is approximately 8.9
