Answer

If we had a sale price of 30% off of $1,050then the sale price is 70% of $1,050 or 0.7(1050) Then we add 7% sales tax to that making thefinal price paid 107% of [0.7(1050)] ... 1.07[0.7(1050)] = $786.45

The average amount that a college student spends on a textbook is $205. What is the probability that a students spends between $
garri49 [273]

Complete question :

The average amount that a college student spends on a textbook is $205 with a

standard deviation of $35. What is the probability that a student spends:

A. between $10 and $310?

Answer:

0.999

Step-by-step explanation:

Mean, m = 205 ; Standard deviation, s = 35

Z = (x - m) / s

x = 310

Z = (310 - 205) / 35 = 3

P(z < 3) = 0.99865

x = 10

Z = (10 - 205) / 35 = - 5.57

P(Z < - 5.5)

P(z < 3) - P(z < - 5.5)

0.99865 - 0

= 0.999

HELP ILL GIVE YOU BRAINLIEST
Alex Ar [27]

Answer:

1. Distributive Property

2. Addition Property of Equality

3. Multiplicative Property of Equality

Step-by-step explanation:

1. The 3 is multiplied by each number in the parenthesis

3*10=30

3*2=6

So 3*(10-2x)=30-6x

2. The 30 is subtracted from both sides

30-6x-30 = -6x

6-30 = -24

30-6x-30=6-30

So -6x=-24

3. The -6 is divided from both sides

-6x/-6 = x

-24/-6 = 4

-6x/-6 = -24/-6

So x=4

Need the answer to number 8 pls
Rama09 [41]
We can split it up into

( \frac{x^4+2x^2}{x^2+2})+(  \frac{1}{x^2+2} )= (\frac{x^2(x^2+2)}{x^2+2})+(  \frac{1}{x^2+2} )x^2+\frac{1}{x^2+2}
I see you were supposed to use synthetic division

not sure what the 'related function is'
but as |x| approaches positivie infinity, y approaches positive infinity
as |x| approaches negative infinity, y approaches positive infinity

for the original function
as x approaches positivie infinity x^2+ \frac{1}{x^2+2} approaches positive infinity
as x approaches negative infinity x^2+ \frac{1}{x^2+2} approaches positive infinity
this is due to the x^2 term making it positive

Sati [7]

Answer:

C=25d

Step-by-step explanation:

We write an equation where C or cost is my output and d or days is my input. I should be able to put in any number of days and find the cost. Let's gather some data:

River Ramble

Day 1 $25(1)=25 cost

Day 2 $25(2)=50 cost

Day 3 $25(3)=75 cost

Day d $25(d)=C.

Our equation is C=25d.
