Answer:
b=60
Step-by-step explanation:
6+4/5b=9/10b
-4/5b -4/5b
6=1/10b
divide both sides by 1/10
b=60
Answer:
The total area of the surface of a three-dimensional object.
Step-by-step explanation:
Answer:
9x2 +42x + 24 <u>is</u> (x + 4) (9x + 6)
9x2 + 30x + 24 <u>is</u> (3x + 6) (3x + 4)
9x2 + 58x + 24 <u>is</u> (9x + 4) (3x + 4)
I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)
Your answers will be:
x= 0.44
and
x= -1.84
Answer: 90% confidence interval would be
Step-by-step explanation:
Since we have given that
n₁ = 50
Number of metal tagged penguins survived = 10
So, 
n₂ = 50
Number of electronic tagged penguins = 18
So, 
So, at 90% confidence interval, z = 1.28
So, interval would be
Hence, 90% confidence interval would be
