Answer:
Lets solve = 3/5 ÷ 1/2
3/5 ÷ 1/2
= 3/5 × 2/1
= 3 × 2/5 × 1
= 6/5
In mixed fraction its

____________________
Now lets solve "a" option
3/5 × 2
= 3 × 2/5 × 1
= 6/5
In mixed fraction

So option a = 3/5 x 2/1 is ur answer
Answer:

Step-by-step explanation:
From the question we are told that:
Sample size 157
Sample mean



Generally the equation for Standard deviation is mathematically given by



Therefore



Answer:

Step-by-step explanation:
Hi there!
Because we're given the vertex of the parabola, we can determine its equation in vertex form:
where the vertex is 
Plug in the vertex (0,0)

Now, we must solve for a. Plug in the given point (-2,3) and solve for a:

Therefore, the value of a is
. Plug this back into
:

I hope this helps!
