Answer:
A = 60
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
119 = 3y+14 + 4y
Combine like terms
119 = 7y+14
Subtract 14 from each side
119-14 = 7y+14-14
105 = 7y
Divide each side by 7
105/7 = 7y/7
15 = y
We want to find Angle A
A = 4y
A = 4*15
A = 60
Answer:
Your reading speed will increase if you're reading a book you're familiar with than one you barely know. So, on average, you can read 40 to 50 pages of a book in an hour.
Step-by-step explanation:
Answer: The answer is A
Step-by-step explanation: Add the coefficient of x to the both sides.
X²+4x=12
X²+4x+4=12+4
X²+4x+4=16
X²+2x+2x+4=16
X(x+2)+2(x+2)=16
(X+2)(x+2)=16
(X+2)²=16
Answer: 95% confidence interval would be (0.555,0.745).
Step-by-step explanation:
Since we have given that
n = 97
x = 63
So, we get that
At 95% confidence interval , z = 1.96
so, Margin of error would be
So, interval would be
Hence, 95% confidence interval would be (0.555,0.745).
I believe multiply then 3
