Answer:
9). 15 miles
10). 12880.8 in²
Step-by-step explanation:
9). Total distance to be covered by Kelly = Perimeter of the given triangle
= Sum of three sides of the triangle
To know the length of Laurel drive (Hypotenuse of the triangle), we will apply Pythagoras theorem in the given triangle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
= (2.5)²+ 6²
= 6.25 + 36
Hypotenuse = [tex]\sqrt{42.25}[/tex]
= 6.5 mi.
Therefore, total distance covered by Kelly = 6.5 + 2.5 + 6
= 15 mi.
10). Amount of paper required to cover one desk of the class
= Area of the trapezoid shown in the figure
= [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Here, [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides of the trapezoid
And 'h' is the distance between the parallel sides.
By applying Pythagoras theorem in ΔPRT,
PR² = RT² + PT²
PT = [tex]\sqrt{PR^2-RT^2}[/tex]
PT = [tex]\sqrt{(18)^2-2^2}[/tex]
= [tex]\sqrt{324-4}[/tex]
= [tex]\sqrt{320}[/tex]
= 17.89 in.
Area of the trapezoid PQRS = [tex]\frac{1}{2}(PQ+RS)(PT)[/tex]
= [tex]\frac{1}{2}(22+26)(17.89)[/tex]
= 429.36 in²
Therefore, paper required to cover 30 desks = 30 × 429.36
= 12880.8 in²

Answer:
41.67
Step-by-step explanation:
1.) Set up a proprotion
[tex]\frac{5.6}{x}[/tex]=[tex]\frac{20}{x+30}[/tex]
2.) Next solve! Cross multiply.
so we get..
5.6(x+30)= 20x
5.6x+168= 20x
5.6x-20x= -168
x= 11.67
3.) We have found x, but they are asking us for the whole length of AB! So just add 30 to x or 11.67
x+ 30= length of AB
11.67+30= 41.67
There are for the length of AB is 41.67!
Two professors are applying for grants. Professor Jane has a probability of 0.61 of being funded. Professor Joe has probability 0.29 of being funded. Since the grants are submitted to two different federal agencies, assume the outcomes for each grant are independent. Give your answer to four decimal places.
Required:
a. What is the probability that both professors get their grantsfunded? Give your answer to four decimal places.
b. What is the probability that at least one of the professors will befunded? Give your answer to four decimal places.
c. What is the probability that Professor Jane is funded but ProfessorJoe is not? Give your answer to four decimal places.
d. Given at least one of the professors is funded, what is theprobability that Professor Jane is funded but Professor Joe is not?
Answer:
a) 0.1769 = 17.69% probability that both professors get their grants funded.
b) 0.7231 = 72.31% probability that at least one of the professors will be funded.
c) 0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.
d) 0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not
Step-by-step explanation:
a. What is the probability that both professors get their grants funded?
Jane has a 0.61 probability of being funded.
Joe has a 0.29 probability of being funded.
So
[tex]p = 0.61*0.29 = 0.1769[/tex]
0.1769 = 17.69% probability that both professors get their grants funded.
b. What is the probability that at least one of the professors will be funded?
None:
Jane has a 1 - 0.61 = 0.39 probability of not being funded.
Joe has a 1 - 0.29 = 0.71 probability of not being funded.
0.39*0.71 = 0.2769
At least one:
1 - 0.2769 = 0.7231
0.7231 = 72.31% probability that at least one of the professors will be funded.
c. What is the probability that Professor Jane is funded but Professor Joe is not?
Jane has a 0.61 probability of being funded.
Joe has a 1 - 0.29 = 0.71 probability of not being funded.
0.61*0.71 = 0.4331
0.4331 = 43.31% probability that Professor Jane is funded but Professor Joe is not.
d. Given at least one of the professors is funded, what is the probability that Professor Jane is funded but Professor Joe is not?
0.4331/0.7231 = 0.5989
0.5989 = 59.89% probability that Professor Jane is funded but Professor Joe is not

What is m
Look at the image above
Answer:
m∠F = 90°
Step-by-step explanation:
By the property of a kite,
"One pair of the opposite angles are congruent"
m∠E ≅ m∠G
m∠E = m∠G = 113°
Sum of the interior angles of a polygon = (n - 2) × 180°
Here, n = number of sides of the polygon
For a kite, n = 4
Therefore, sum of the interior angles of the given kite = (4 - 2) × 180°
= 360°
Therefore, m∠E + m∠F + m∠G + m∠H = 360°
113° + m∠F + 113° + 44° = 360°
m∠F = 360° - 270°
m∠F = 90°

Heart failure is due to either natural occurrences (89%) or outside factors (11%). Outside factors are related to induced substances or foreign objects. Natural occurrences are caused by arterial blockage, disease, and infection. Assume that causes of heart failure between individuals are independent.
A) What is the probability that the first patient with heartfailure that enters the emergency room has the conditions due tooutside factors?
B) What is the probability that third patient with heartfailure that enters the emergency room is the first one due tooutside factors?
C) What is the mean number of heart failure patients with thecondition due to natural causes that enter the emergency roombefore the first patient with heart failure from outsidefactors?
Answer:
a) 11% probability that the first patient with heart failure that enters the emergency room has the conditions due to outside factors.
b) 0.0871 = 8.71% probability that third patient with heart failure that enters the emergency room is the first one due to outside factors.
c) The mean number of heart failure patients with the condition due to natural causes that enter the emergency room before the first patient with heart failure from outside factors is 9.09.
Step-by-step explanation:
We have these following probabilities:
89% probability that a patient has heart failure due to natural occurrences.
11% probability that a patient has heart failure due to outside factors.
A) What is the probability that the first patient with heart failure that enters the emergency room has the conditions due to outside factors?
We assume that causes of heart failure between individuals are independent, which means that the probabilities are the same for each patient. So:
11% probability that the first patient with heart failure that enters the emergency room has the conditions due to outside factors.
B) What is the probability that third patient with heart failure that enters the emergency room is the first one due to outside factors?
First two due to natural occurrences, each with 89% = 0.89 probability.
Third due to outside factors, with 11% = 0.11 probability. So
0.89*0.89*0.11 = 0.0871
0.0871 = 8.71% probability that third patient with heart failure that enters the emergency room is the first one due to outside factors.
C) What is the mean number of heart failure patients with the condition due to natural causes that enter the emergency room before the first patient with heart failure from outside factors?
11% with outside factors, so the mean number of patients before the first with outside factors is given by
m = 1/0.11 = 9.09
The mean number of heart failure patients with the condition due to natural causes that enter the emergency room before the first patient with heart failure from outside factors is 9.09.

Stefani received a loan for $2,000 and now has acquired $720 in interest. If she pays an annual interest of 4.5% on the amount borrowed. how much time has elapsed since Stefani received the loan?
Answer:
8 years.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.5%/100 = 0.045 per year,
then, solving our equation
t = 720 / ( 2000 × 0.045 ) = 8
t = 8 years
The time required to
accumulate simple interest of $ 720.00
from a principal of $ 2,000.00
at an interest rate of 4.5% per year
is 8 years.

Write the equation of the line that has m = -1/3 and goes through the point (-9, -1). Write the equation in slope-intercept form.
Step-by-step explanation:If you want to find the equation of line with a given a slope of -8 which goes through the point (6,9), you can simply use the point-slope formula to find the equation:
---Point-Slope Formula---
y-y%5B1%5D=m%28x-x%5B1%5D%29 where m is the slope, and is the given point
So lets use the Point-Slope Formula to find the equation of the line
y-9=%28-8%29%28x-6%29 Plug in m=-8, x%5B1%5D=6, and y%5B1%5D=9 (these values are given)
y-9=-8x%2B%28-8%29%28-6%29 Distribute -8
y-9=-8x%2B48 Multiply -8 and -6 to get 48
y=-8x%2B48%2B9 Add 9 to both sides to isolate y
y=-8x%2B57 Combine like terms 48 and 9 to get 57
------------------------------------------------------------------------------------------------------------
Answer:
So the equation of the line with a slope of -8 which goes through the point (6,9) is:
y=-8x%2B57 which is now in y=mx%2Bb form where the slope is m=-8 and the y-intercept is b=57
A student claims that if y-values are not increasing as x-values increase, then the data must show a negative association. Explain the error the student made.
Answer:
Because it can just stay constant. It may not change at all, so that's not a negative association
Step-by-step explanation:
What will be the result of substituting 2 for x in both expressions below? One-half x + 4 x + 6 minus one-half x minus 2 Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Both expressions equal 6 when substituting 2 for x because the expressions are equivalent. One expression equals 5 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent. One expression equals 6 when substituting 2 for x, and the other equals 2 because the expressions are not equivalent.
Replace x with 2 and solve each equation:
1/2(2) + 4 = 1 + 4 = 5
2+ 6 -1/2(2) -2 = 8-3 = 5
The answer is:
both expressions equal 5 when substituting 2 for x because the expressions are equivalent.

Rambo-Conduit Corporation manufactures plastic conduit that is used in the cable industry. A conduit is a tube that encircles and protects the underground cable. In the process of making the plastic conduit, called extrusion, the melted plastic (resin) is pressed through a die to form a tube. Scrap is produced in this process. Information from the cost of production reports for three months is as follows, assuming that inventory remains constant:
May June July
Resin pounds input into the process 470,000 700,000 650,000
Price per pound X$1.50 X$1.50 X$1.50
Plastic material costs $493,000 $640,000 $677,000
Conversion costs $80,000 $120,000 $115,000
Conduit output from the process (feet) 800,000 1,200,000 1,130,000
Assuming that there is one-half pound of resin per foot of the finished product, determine the resin materials cost per foot of finished product for June.
a. $0.53
b. $0.60
c. $0.54
d. None of these choices are correct.
Answer:
The resin materials cost per foot of finished product for June is $0.53
Option a) $0.53 is the right answer
Step-by-step explanation:
Given the data in the question;
May June uly
Resin pounds input
into the process 470,000 700,000 650,000
Price per pound X$1.50 X$1.50 X$1.50
Plastic material costs $493,000 $640,000 $677,000
Conversion costs $80,000 $120,000 $115,000
Conduit output from
the process (feet) 800,000 1,200,000 1,130,000
Assuming that there is one-half pound of resin per foot of the finished product, determine the resin materials cost per foot of finished product for June.
Now;
Materials cost for June = $640,000
Number of Feet produced as output in June = 1,200,000
so
Material Cost per feet of finished product will be;
= $640,000 / 1,200,000
= $0.5333 ≈ $0.53
Therefore, the resin materials cost per foot of finished product for June is $0.53
Option a) $0.53 is the right answer

If a number is multiplied by 7, the result is the same as when 25 is added
to twice the number. Find the number.
Answer:
Step-by-step explanation:
"a number is multiplied by 7" can be represented by 7x
"25 is added to twice the number" can be represented by 2x+25
7x = 2x+25
5x = 25
x = 5
The number is 5 if a number is multiplied by 7, the result is the same as when 25 is added to twice the number.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the number is x:
From the problem, we can model a linear equation in one variable.
7x = 2x + 25
5x = 25
x = 5
Thus, the number is 5 if a number is multiplied by 7, the result is the same as when 25 is added to twice the number.
