Answer:
Yes, the answer is C {3,5,7}
Domain of a function is the input value and range is the result or output value that we get.
You can fit 153 flowers in a circle with the diameter of 14. You find the area of the circle by doing pi times 7 squared.
Answer:
The height of the roof is 534.8 feet.
Step-by-step explanation:
Let h be the height of the roof.
We know the formula
Since, the stone is dropped from the edge of the roof hence, the initial velocity should be zero. Thus, u = 0
Now, we have
v = -185 feet per second
g = 32 feet per square second
On substituting these values, we get
The height of the roof is 534.8 feet.
Answer:
the probability that a sample of 4 bags will have a mean weight less than 9.8 pounds is 0.05
Step-by-step explanation:
Given the data in the question;
μ_x = 10 pound bags
standard deviation s_x = 0.24 pounds
sample size n = 4
The bag weights are normally distributed so;
p( x' less than 9.8 ) will be;
p( (x'-μ_x' / s_x') < (9.8-μ_x' / s_x') )
we know that;
μ_x' = μ_x = 10
and s_x' = s_x/√n = 0.24/√4
so; we substitute
p( z < ( (9.8 - 10) / (0.24/√4) )
p( z < -0.2 / 0.12 )
p( z < -1.67 )
{ From z-table }
⇒ p( z < -1.67 ) = 0.0475 ≈ 0.05
Therefore, the probability that a sample of 4 bags will have a mean weight less than 9.8 pounds is 0.05
