Answer:

x = 125°

Step-by-step explanation:

The sum of angles in an n-sided polygon is (180°)(n -2). For a hexagon, the sum of angles is ...

(180°)(6 -2) = 720°

We can use this to find x.

x +117° +124° +102° +145° +107° = 720°

x = 720° -595°

x = 125°

SCORPION-xisa [38]

<u>Answer:</u>

The available amount for the down payment of car and invested $3,200 at 3.75% interest compounded continuously is 3449.23$

<u>Explanation:</u>

We know final amount is given by

Where,

$A=P \times e^{r t}$

A = final amount

P = initial principal balance = $3200

r = interest rate = 3.74%

t = number of time periods elapsed = 2 years

Substituting the values in the formula

$r=\frac{3.75}{100}=0.0375$

A= $3200 \times e^{(0.0375 \times 2)}$

We know, e = 2.72

So we get A = 3449.23$ which is the available amount for the down payment of car .

an instructor grades on a curve by assuming that grades on a test are normally distributed. If the average grade is 80 and the s

sweet [91]

Step-by-step explanation:

According to normal distribution curves following a bell curve formula, it is followed that

34% of people will lie between Mean point and one positive standard deviation

34% of people will lie between Mean point and one negative standard deviation

14% of people will lie between Mean point and two positive standard deviation

14% of people will lie between Mean point and two negative standard deviation

2% of people will lie between Mean point and three positive standard deviation

2% of people will lie between Mean point and three negative standard deviation

Now following this principle, we are given that mean score is 80 and standard deviation is 8, hence the interval for grades would be;

Grade A ; Score greater than 96

Grade B : Score greater than 88 and less than or equal to 96

Grade C : Score greater than 80 and less than or equal to 88

Grade D : Score greater than 72 and less than or equal to 80

Grade E : Score greater than 64 and less than or equal to 72

Grade F : Score less than 64
