The 4 becomes 8/-7 because 4×2/-7 =8/-7
To find this, first we have to find the square root of 200, which is about 14.14
Now we multiply 14.14 * 4 = 56.56
So Rae will need about 56.56 feet of fencing to surround the garden.
The following are the answers to
the questions presented:
Part 1:
Vertex: <span>(<span><span>−3</span>/ 2</span>,<span> 11/2</span>)</span>
Axis of
symmetry = x = -3/2
Domain = all
real numbers
Range = <span>y </span><span>≤ </span>11/2
Part 2:
A quadratic equation is symmetrical around its vertex. The
equation for the axis of symmetry is x = -3/2 since the equation is in terms of
x. Since no value of x is undefined, then the domain of the equation is clearly
all real numbers. Since the value of “a” is negative, then that means the y
coordinate of the vertex is the maximum value so the range will never get above
11/2. I am hoping that these answers have satisfied your queries and it
will be able to help you in your endeavors, and if you would like, feel free to
ask another question.
Answer:
The right solution is "-8.25".
Step-by-step explanation:
The given values are:
Sampled people,
n = 150
Null and alternative hypotheses will be:
The z-statistics will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
⇒ 
Cross multiply then solve for x:
3/2 * 125/x
2*125 = 250
3 * x = 3x
3x = 250
x = 83.33 = 83 (rounded)
