Answer:
1+3i
Step-by-step explanation:
i is a variable. -1 has an absolute value of 1. 3i is multiplying i by 3.
That would be 1/2 divided by 3
Its A
a triangle needs to have 180 degrees in all.
65 + 65 = 130
180 - 130 = 50
x = 50 degrees
Answer:
y = -1|x+1| +1
Step-by-step explanation:
The vertex form of an absolute value equation is y = a* |x-h| +k
a = -1 because it opens downwards with a slope of ± 1. Next it's vertex is at (-1,1). So replace h with -1 and k with one.
y = -1|x+1|+1
Answer: 0.0221
Step-by-step explanation:
We know that the formula to find the standard deviation of the sample proportion is :

, where p = proportion of success.
n= sample size.
As per given , we have
p=0.58
n= 500
Then, the standard deviation of the sample proportion in this situation would be :

Hence, the standard deviation of the sample proportion in this situation is 0.0221 .
