Answer: I think I cn help bt nt sure
Step-by-step explanation:
X° + 52° + 78° = 180°
X° + 130° = 180°
X° + 130° - 130° = 180° - 130 °
X° = 50°
M is <50°
Answer: 86.64%
Step-by-step explanation:
Let x be a random variable that represents the diameter of metal samples.
Given : Population mean : 
Standard deviation: 
Specified tolerance on the diameter is 0.75 mm.
i.e. range of diameter = 10-0.75< x <10+0.75 = 9.25< x< 10.75
Formula to find the z-score corresponds to x: 
At x= 0.75, 

Using standard normal table for z-value,
P-value : 
∴ Percentage of samples manufactured using this process satisfy the tolerance specification = 86.64%
Answer:
x intercept (36, 0)
y intercept (0, 9)
Step-by-step explanation:
x intercept when y = 0 so x = 36
y intercept when x = 0 so 4y = 36; y = 9
Answer
x intercept (36, 0)
y intercept (0, 9)
Answer: a<13
Step-by-step explanation:
a*(a+1)<a^2+13
a^2+a<a^2+13
subtract a^2 from both sides:
a<13
