Answer: Just guessing, try.. or dont.

Step-by-step explanation:

There are 3 seniors. To make up 100% we would have to do 33.33%. I would say that the probabilty is around 33.33, and don't know the different orders possible.

ITS TIMED PLEASE HELP

Answer:

The graph of the function $f(x)=\frac{1}{2}x^{2}-4x+5$ has a minimum located at (4,-3)

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

$f(x)=a(x-h)^{2}+k$

where

a is a coefficient

(h,k) is the vertex of the parabola

If a > 0 the parabola open upward and the vertex is a minimum

If a < 0 the parabola open downward and the vertex is a maximum

In this problem

The coefficient a must be positive, because we need to find a minimum

therefore

Check the option C and the option D

Option C

we have

$f(x)=\frac{1}{2}x^{2}-4x+5$

Convert to vertex form

$f(x)-5=\frac{1}{2}x^{2}-4x$

Factor the leading coefficient

$f(x)-5=\frac{1}{2}(x^{2}-8x)$

$f(x)-5+8=\frac{1}{2}(x^{2}-8x+16)$

$f(x)+3=\frac{1}{2}(x^{2}-8x+16)$

$f(x)+3=\frac{1}{2}(x-4)^{2}$

$f(x)=\frac{1}{2}(x-4)^{2}-3$

The vertex is the point (4,-3) ( is a minimum)

therefore

The graph of the function $f(x)=\frac{1}{2}x^{2}-4x+5$ has a minimum located at (4,-3)

Rearrange x = 7y - 5 to make y the subject.

nalin [4]

By rearranging x = 7y - 5 to make y the subject, we get

x + 5 = 7y ( By transposition method )

or, $\huge \purple {\tt {\frac{x + 5}{7} = y}}$

<h2>Answer:</h2>

$\huge \pink {\tt {y = \frac{x + 5}{7}}}$

An item that originally cost $100 is decreased by 8%. The reduced price is then increased by 8%.

VARVARA [1.3K]

Answer:

first, find the decreased price by multiplying 100 by 8% and subtracting:

100 x 0.08 = 8

100-8 = 92 ( reduced price )

now multiply reduced price by 8% and add:

92 x 0.08 = 7.36

92 + 7.36 = $99.36
