During the past week, an accounting firm made a total of 77 long distance calls to its clients. Twenty-four of the calls were less than or equal to 30 minutes in duration while 41 of the calls were less than or equal to 40 minutes. The longest call was one hour and fifty-five minutes and the tenth percentile of the length of calls was 20 minutes.
Step 4 of 5 : What percentage of the calls were greater than 30 minutes in duration? Round your answer to the nearest whole number percentage.
The percentage of the calls were greater than 30 minutes in duration is 69%.
How to illustrate rye information?Let N = 77 Total long-distance calls
X= 24 calls are less than or equal to 30 minutes duration
Y = N - X= 77 - 24= 53 calls are greater than 30 minutes duration
To find the percentage of calls greater than 30 minutes duration. This goes thus:
= Number of calls greater than 30 minutes / Total calls
= 53 / 77
= 0.69
Therefore, 69% of the call were greater than 30 minutes in duration.

Create a polynomial that has 4 terms, a degree of 6, a leading coefficie
and a constant term of -5.5.
-6 is the product of this equation,
therefore there are no constant term or leading coefficient.

Determine whether the following procedure results in a binomial distribution or a distribution that
can be treated as binomial (by applying the 5% guideline for cumbersome calculations). If it is not
binomial and cannot be treated as binomial, identify at least one requirement that is not satisfied.
In a Pew Research Center survey of 150 subjects, the ages of the respondents are
recorded.
The correct statement regarding whether the situation results in a binomial distribution is:
C. It is not binomial because there are more than two possible outcomes.
What is required for the binomial distribution to represent a situation?Three things are needed for a situation being represented by the binomial distribution:
Each trial having only two possible outcomes, one equivalent to success and one to failure.Fixed number of trials.Each trial is independent, that is, the probability of a success on a single trial is independent of any other trial.For this problem, for each respondent, there are multiple possible ages, a number greater than 2, hence the binomial distribution cannot be used and option c is correct.
The trials are independent, because the age of a respondent is not related to the age of any other respondent, hence option b is wrong.

b. Distance from here to the moon
c. Area of a circle

e. The height of a ball as it is thrown into the air.
f. The balance in an account over a week.
The variables are:
a) discrete.
b) continuous.
c) continuous.
d) discrete.
e) continuous.
f) discrete.
Is the situation an example of a continuous or discrete relation?A continuos variable can take any value in a dense set, while a discrete variable can only take some selected values.
a) "Bag of apples"
Here the variable is the number of apples in the bag, we can only have whole numbers of apples, then this variable is discrete.
b) "Distance from here to the moon"
This is a distance, so the value is continuous.
c) "Area of a circle"
Exactly like in the case above, the area is continuous.
d) "Number of telephone calls made each day"
Like in the first example, here the variable can only take whole numbers thus, it is discrete.
e) "The height of a ball as it is thrown into the air."
Similar than case b, a height can take any value on a given range, thus, this is continuous.
f) "The balance in an account over a week."
Here the balance can only be a number followed by 2 digits after the decimal point, so from:
$23.50
We can only go up to:
$23.51
Then all the values in between are not allowed, this means that the variable is discrete.

find the measures of the angles of a triangle if the angles are resented by x, 4x, and 4x. show work
x = 20
Step-by-step explanation:Total degrees of a triangle = 180 degrees.
The three angles are x, 4x & 4x
x + 4x + 4x = 180 degrees
x + 8x = 180 degrees
9x = 180 degrees
(9x)/9 = 180/9
x = 180/9

three lakes lost water during a drought. Lake Jensen lost 1/6 of its water, Lake parlow lost 26% of its water, and lake stockton lost 33/200. which lake lost the least amount of water whats the answer?
Answer:
lake stockton
Step-by-step explanation:
26% is equal to 26/100
you have to figure out a common denominator for all three numbers. the easiest for me was 600
to get from 1/6 to x/600 you multiply by 6 so you do the same to the top. equaling 100/600
for 26/100 you times top and bottom by 6 equaling 156/600
for 33/200 you multiply by 3 on both equaling 99/600
now you can clearly see that 99/600 is the least amount
Find the distance between each pair of points. The points are (3,-5) and (-2,0)
Answer:
5√2
Step-by-step explanation:
The distance formula is the the square root of the difference of the x (delta x) squared plus the difference of the y (delta y) squared. So, you would do
0 - (-5) = 5 & -2 - (3) = -5
Then
5² + (-5)² = 25 + 25 = 50
Square root 50

Beth purchased a $50,000 nonparticipating whole life insurance policy. The annual premium was $1,608. The cash value of the policy after 10 years will be $13,740. Assuming 5% interest rates. What is the traditional net cost of this policy, per thousand per year, over the first 10 years the policy is in force? (Round your answer to 2 decimal places)
Based on the annual premium, the cash value of the policy, and the number of years, the traditional net cost of this policy over the first 10 years is 5.76.
What is traditional net cost?First, find the net cost over 10 years:
= Total premium over 10 years - cash value
= (1,608 x 10) - 13,740
= $2,340
The net cost per year is:
= 2,340 / 10
= $234
The traditional net cost of this policy, per thousand per year for the first 10 years is:
= 234 / 50,000 x 1,000

W X and ←→ Y Z intersect at point V. If m ∠ W V Y = ( 4 a + 58 ) ° and m ∠ X V Y = ( 2 b − 18 ) ° , find the values of a and b such that ←−→ W X is perpendicular to ←→ Y Z
The values of a and b are 8 and 54 respectively.
As WX and YZ are perpendicular to each other and they intersect at point V, so both ∠WVY and ∠XVY are 90°.
Given that,
∠WVY = (4a + 58)°
∠XVY = (2b - 18)°
Which means:
4a + 58 = 90
4a = 90-58
4a = 32
a = 32/4
a = 8
and 2b - 18 = 90
2b = 90+18
2b = 108
b = 108/2
b = 54°
hence we get the values of a and b as 8° and 54°
