Step-by-step explanation:
we know that
The sum of the interior angles in any polygon is given by the formula
where
n is the number of sides of the polygon
step 1
Find the sum of the interior angles in the given polygon
we have
substitute
step 2
Find the value of x
we know that
solve for x
step 3
Find the measure of each interior angle
substitute the value of x
Angle A
Angle B
Angle C
Angle D
Angle E
Answer:
555.56
Step-by-step explanation:
Purpose of the study: To determine if women are better drivers than men.
Survey or Opinion population: 1,000
You are experimenting on 9 out of a thousand opinions.
5 of these opinions are that women are better drivers
4 of these opinions are that women are not better drivers
You want to know the <em>sample</em> (full sample size is 9) <em>proportion</em> for women as better drivers; using the large sample method. This method is also called the asymptotic method.
This involves approximating the desired statistic, with just a small fraction of the population; in this case, 9/1000.
This approximation will get more and more accurate as sample size increases and you know that a larger sample size gives a better representation and interpretation of the population preference!
So using ratio, the sample proportion for women as the better drivers is given by:
5/9 x 1000 = 555.56 opinions
Answer:
19 are blue
37
Step-by-step explanation:
35 - 16 = 19
35 + 3 = 38 & 75 - 38 = 37
Answer:
4.5 hours
Step-by-step explanation:
So, let's write a function p(x) which represents the total cost.
Let's let x represent the amount of hours.
The cost of a piece is a constant 10.
And there is a $8 fee per hour. In other words:
We spent a total of $46.
So, substitute in 46 for p(x) and solve for x:
Subtract 10 from both sides:
Divide both sides by 8:
Reduce:
So, we spent about 4.5 hours.
3 +6=9 and 3-6 =-3. that’s all you need to do
