The correct answer is:  [C]:  " $4290.00 " .
_______________________________________
Explanation:
_________________________________________
Given:  principal, "P":  equals:  $14,300  ;
                 rate, "r" : equals:  7.5 %  = 7.5 / 100 = 0.075 ; 
                time, "t" (in years): equals:  4  ;
_________________________________________
What is the interest, "i" ? 
_________________________________________
  Note:  The formula:  i = P * r * t   .
_________________________________________
So, we plug in our given values for "P", "r", and "t", and solve for "i" (interest).
__________________________
i = ($14,300) *(0.075) * (4)  ;

i = $1,490 ;  which is answer choice:  [C]:  " $4290.00 " .

Four triangle are shown above based on these triangles which statement is true?
liubo4ka [24]

Answer:

B

Step-by-step explanation:

Because the number of degrees in a triangle is 180 degrees so x = 180 - (45 + 60) = 75. Now w + 75 = 180 , therfore w = 105 degrees.

Assume that a set of test scores is normally distributed with a mean of 70 and a standard deviation of 10. In what percentile is
vlabodo [156]
Given:
μ = 70, the mean
σ = 10, the standard deviation

The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5

From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.

Answer: 30th

I need the answer and the work! <br> you have to find n.
zloy xaker [14]

Tell you what I'll do:  I'll show you the work, for two of them.
Then, knowing how to do it, you'll find the answers.
Deal ?

#1). n + (-13) = -12

Remove the parentheses
on the left side:                     n - 13 = -12

Add  13  to each side:           n        =    1

================================

#3).                        -15 + n  =  3

Add  15  to each side:     n  =  18


OK.  Look those over, understand how they're done, then TAKE IT !
