This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
Hope this helps!
Answer:
slope=1/3
Step-by-step explanation:
y=mx+b
2=m*6+0
m=1/3
10.1*2.1*2.11 is 3 decimals
Answer:
The mean is 0.32 and the standard deviation is 0.0122.
Step-by-step explanation:
Given that the Tampa Times polled 1,457 adults in the city to determine whether they put on their shirt before they put on their pants.
Of the respondents, 48% said they put their shirt on first.
32% of all adults actually put their shirt on first
i.e. sample proportion is 48% while population proportion is 32%
Hence sampling distribution follows a distribution with mean = population proportion p
Hence here mean = 0.32
Std deviation of sampling distribution = 
Hence option 3) The mean is 0.32 and the standard deviation is 0.0122.
is right
-3x(-7) = -3(-2)(-7) ⇒ -42
-42 would be the answer.
