A rectangular carport has area of one 50 ft.The width of the carport is 5 feet less than twice its length. Find the length and width of the carport
Width= ? feet,
Length= ? feet
Answer:
It is 10 because 5 times 10 is 50
Answer:
A) = 5
B) = 10
C) = (5 x 10)= 50
Step-by-step explanation:
Area of a rectangle a x b = c
Where a is the short side
Where b is the long side
And c is our area
Okay now we we have to think what numbers give us 50 so ( 1 x 50 , 5 x 10 , 2 x 25)
So since now we have the numbers we look for a number that is twice the other and is - 5 the other one and the only numbers are 10 and 5 so in conclusion
A= 5
B= 10
C= 50

A university researcher wants to estimate the mean number of novels that seniors read during their time in college. An exit survey was conducted with a random sample of 9 seniors. The sample mean was 7 novels with standard deviation 2.29 novels. Assuming that all conditions for conducting inference have been met, what is a 95 percent confidence interval for the population mean number of novels read by all seniors?
Answer:
(5.240 ; 8.760)
Step-by-step explanation:
Given :
Sample mean, xbar = 7
Standard deviation, s = 2.29
Sample size, n = 9
95% confidence interval for the population mean :
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 0.05 ; df = 8 = 2.306
Margin of Error = 2.306 * 2.29/sqrt(9)
Margin of Error = 1.760
Lower boundary = (7 - 1.760) = 5.240
Upper boundary = (7 + 1.760) = 8.760
(5.240 ; 8.760)

The graph of the function
Answer:
A. the function is increasing for all real values of x where x < -4
What is the range of the function graphed below?
Answer:
-3<y<=3 or B
Step-by-step explanation:
first we find the smallest y value which is -3
then we find the largest y vlaue which is three
so since there is an open circle at negative three we do not include it while at three we do.
so the answer would be -3<x<=3

Find the slope of the line by comparing the change in y to the change in x.
Answer:
3/4
Step-by-step explanation:
i was just learning this stuff
The slope of the line = 3/4
What is slope?"It is the ratio of change in the y values to the change in x values"
From given graph,
Consider AB,
assuming scale of 1 unit on each axis,
change in y = 3 and the change in x = 4
Therefore, the slope of the line = 3/4

Use △GHJ, where A, B, and C are midpoints of the sides.
When GH = 7z−1 and CB = 4z−3, what is GA?
Answer:
GA=17
Step-by-step explanation:
As A, B, C are the midpoints of the sides of AGHJ,
so GH= 2(CB)
⇒7z-1= 2(4z-3)
⇒7z-1= 8z-6
⇒7z-8z= -6+1
⇒-7= -5
z=5
so GA=CB
⇒GA= 4(5)-3= 17

The value of the variable 'z' is 5. Then the length of GA will be 17 units.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Use △GHJ, where A, B, and C are midpoints of the sides. When GH = 7z − 1 and CB = 4z − 3.
From the graph, then the condition is given as,
GH = 2 × BC
7z - 1 = 2 × (4z - 3)
Simplify the equation, then we have
7z - 1 = 2 × (4z - 3)
7z - 1 = 8z - 6
6 - 1 = 8z - 7z
z = 5
Then the length of the GA is given as,
GA = BC
GA = 4z - 3
GA = 4 (5) - 3
GA = 20 - 3
GA = 17 units
The value of the variable 'z' is 5. Then the length of GA will be 17 units.

Consider a taxi station at an airport where taxis and (groups of) customers arrive at times of Poisson processes with rates 2 and 3 per minute. Suppose that a taxi will wait no matter how many other taxis are present. However, if an arriving person does not find a taxi waiting he leaves to find alternative transportation. (a) Find the proportion of arriving customers that get taxis. (b) Find the average number of taxis waiting
Answer:
a) [tex]\pi(0)=\frac{1}{3}[/tex]
b) [tex]X=\frac{2}{3}[/tex]
Step-by-step explanation:
From the question we are told that:
Arrival time with Poisson's process =[tex]t_p=2-3minutes[/tex]
where
[tex]\lambda_1=2\\\lambda_2=3[/tex]
a)
Generally the equation Poisson's process is mathematically given by
[tex]\pi()n*\lambda_1=\pi(n+1*) \lambda_2[/tex]
[tex]\pi()n*2=\pi(n+1*)*3[/tex]
[tex]\pi(n+1)=\frac{2}{3} \pi+1*\pi(0)[/tex]
Therefore
[tex]\pi(0)(1+2/3+(2/3)^2+...)=1[/tex]
[tex]\pi(0)=\frac{1}{3}[/tex]
The proportion of arriving customers that get taxis.
[tex]\pi(0)=\frac{1}{3}[/tex]
b)
Generally the average number of taxis X waiting is mathematically given by
[tex]X=1-\pi(0)\\X=1-(1/3)[/tex]
[tex]X=\frac{2}{3}[/tex]
