Hey there!

We know that Tara saves 1/5 th of her money every week.

We know the amount Tara get is $228.75 per week.

The amount saved per week =

(1/5) × 228.75

= $45.75

She saves $45.75 per week.

We know that we have about 4 weeks in each month.

In 2 months we will have 8 weeks.

The amount saved after 8 weeks would be =

45.75 × 8

366

<em>Hence, the saved amount is $366.00 </em>

<u><em>Hope it helps!</em></u>

Dmitriy789 [7]

<span>We know that there is no universal acceptance meaning of a percentile. When someone told you that you are in the 80th percentile, the meaning of that is you have achieved the lowest score that is greater than 80 percent of the score. It is calculated by using the formula     <span>R = P/100 x (N + 1)</span></span>

Solve quadratic equation (x-3)^2+5=14
loris [4]
(X-3)^2+5=14
Step 1: simplify both sides of the equation
X^2-6x+14=14

Step 2: subtract 14 from both sides
X^2-6x+14-14=14-14
X^2-6x=0

For this equation: a=1, b=-6,c=0
1x^2+-6x+0=0

Step 3: Use quadratic formula with a=1, b=-6, c=0

The answer is x=6 or x=0

If z=2.5, x=102 and x=100, what is s?
Bad White [126]

I believe the problem ask for s which is the standard deviation. We must recall that the formula for z statistic is stated as:

z = (x – x over bar) / s

Where,

z = z statistic = 2.5

x = sample value or sample score = 102

x over bar = the sample mean or sample average  = 100

s = standard deviation = unknown

Rewriting the equation in terms of s:

s = (x – x over bar) / z

Substituting the given values into the equation:

s = (102 – 100) / 2.5

s = 0.8  

Therefore the standard deviation s is 0.8
