Answer:
x = 15
Step-by-step explanation:
A full circle = 360°
Therefore,
(8x - 10)° + (6x)° + (10x + 10)° = 360°
Solve for x
8x - 10 + 6x + 10x + 10 = 360
Add like terms
24x = 360
Divide both sides by 24
x = 360/24
x = 15
Answer:
Step-by-step explanation:
1: 128+102= 230
2: 230x32= $7360
Answer:
Its 1
Step-by-step explanation:
Prime factorization
45 = 3 × 3 × 5
56 = 2 × 2 × 2 × 7
To find the gcf, multiply all the prime factors common to both numbers
Therefor, it equals 1
Answer: 0.9660
Step-by-step explanation:
Given: Mean :
Variance :
⇒ Standard deviation :
The formula to calculate z is given by :-
For x= -3
The P Value =
For x= 3
The P Value =
Hence, the probability that a given error will be between -3 and 3=0.9660
