1.425 and 17.57 satisfy the equation.
Answer :
<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3>
Step-by-step explanation:
<h3>The average of a distribution is equal to the summation of x divided by the number of observations is called <u>Mean</u></h3><h3>For :</h3>
- We know that
where N is the number of observations
<h3>Therefore the average of a distribution is known as Mean.</h3>
So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.
Answer:
no they're not
Step-by-step explanation:
4(x+2) = 4x +8
4x+2= 4x+2
Answer:
The vertex is (-3,1)
Step-by-step explanation:
Here, we want to write the given function in the vertex form
Mathematically, we have this as;
y = a(x-h)^2 + k
where the vertex is (-h,k)
Thus, we have
Let us divide the coefficient of x by 2, square and add to both sides ; prior to this, we will equate y to 0
Thus, we have it that;
0 = x^2 + 6x + 10
x^2 + 6x + 10 + 9 = 9
x^2 + 6x + 9 = 9-10
x^2 + 6x + 9 = -1
(x + 3)^2 = -1
(x + 3)^2 + 1 = 0
So the vertex here as represented by (-h,k) is;
(-3,1)
