Step-by-step explanation:
Connie Harris, in charge of office supplies at First Capital Mortgage Corp., would like to predict the quantity of paper used in the office photocopying machines per month. She believes that the number of loans originated in a month influence the volume of photocopying performed. She has compiled the following recent monthly data:
Number of Loans Originated in Month Sheets of Photocopy Paper
used (1000s)
45 22
25 13
50 24
60 25
40 21
25 16
35 18
40 25
(a) Develop the least-squares estimated regression equation that relates sheets of photocopy paper used to loans originated.
(b) Use the regression equation developed in part (a) to forecast the amount of paper used in a month when 42 loan originations are expected.
(c) Compute the coefficient of determination r2. Comment on the goodness of fit.
(d) Compute the correlation coefficient.
(e) Is there a significant relationship between the two variables? Use a significance level of 0.05 and explain using numerical examples.
Answers
Answer:
y = 0.325X + 7.5 ;
21.5 ;
R^2 = 0.7655 ;
r = 0.8749
Step-by-step explanation:
No. of loans originated ____ sheets of p/paper
45 ______________22
25 ______________ 13
50 _____________ 24
60 _____________ 25
40 _____________ 21
25 _____________ 16
35 _____________ 18
40 _____________ 25
Using the linear regression calculator : the linear model obtained is:
y = 0.325X + 7.5
y = predicted variable = sheets of photocopy paper
X = number of loans originated
0.325 = slope
Intercept = 7.5
B.)
X = 42
y = 0.325(42) + 7.5
y = 21.15
C.)
The Coefficient of determination as determined using the correlation coefficient calculator is :
R^2 = 0.7655 ; this means that about 76.55% of change in number of photocopy performed is explained by the number of loans originated.
D.) The correlation Coefficient (r) :
r = sqrt(R²)
r = sqrt(0.7655)
r = 0.8749
This shows that a strong positive correlation exists between the number of loans originated and the volume of photocopying done.
Determine the length of AY if ARAY is a 30°-60°-90° triangle and RY has a length of 48 centimeters.
Answers
Answer:
48√3 cm
Step-by-step explanation:
I'm assuming that ∠A = 30°, ∠R = 60°, and ∠Y = 90°.
The sides of a 30-60-90 triangle are in the ratio 1:√3:2.
RY is opposite the 30° angle and has length 48 cm.
AY is opposite the 60° angle, so the length of AY = 48√3 cm.
What is one of the solutions to the following system of equations?
y2 + x2 = 53
y − x = 5
Answers
Answer:
x = 2 and y = 7
Step-by-step explanation:
The given equations are :
[tex]y^2+x^2=53\ ....(1)\\\\y-x=5\ ...(2)[/tex]
Squaring both sides of equation (2)
[tex](y-x)^2=5^2\\\\y^2+x^2-2xy=25\\\\53-2xy=25\ \text{from equation (1)}\\\\2xy=53-25\\\\2xy=28\\\\xy=14\ ...(3)[/tex]
Put the value of y from equation (2)
[tex]x(5+x)=14\\\\5x+x^2-14=0\\\\x=2[/tex]
Put the value of x in equation (2)
y-x = 5
y = 5+x
= 5+2
= 7
Hence, the solution of the given equations are (2,7).

express 1400 as a product of its prime factors in index form write the prime factors in ascending order?
Answers
Answer:
[tex]1400=2^3*5^2*7[/tex]
Step-by-step explanation:
Prime Factors
The first prime numbers are:
{1,3,5,7,11,13,...}
To find the prime factors of any integer number, we successively divide the number by all the possible prime numbers, probably more than once.
Let's find the prime factors of 1400.
Dividing by 2 while possible:
1400/2 = 700
700/2 = 350
350/2 = 175
3 is not a divisor of 175, so we try 5:
175/5 = 35
35/5 = 7
Since the last result is a prime number, no more tries are necessary. The product of prime factors in index form is:
[tex]\boxed{1400=2^3*5^2*7}[/tex]

An object is launched directly in the air at a speed of 72 feet per second from a platform located 12 feet above the ground. The position of the object can be modeled using the function f(t)=−16t2+72t+12, where t is the time in seconds and f(t) is the height, in feet, of the object. What is the maximum height, in feet, that the object will reach?
Answers
Answer:
48
Step-by-step explanation:
For the quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the given quadratic, which defines a parabola opening downward, the axis of symmetry defines the time at which the maximum height is reached.
t = -48/(2(-16)) = 1.5
Then the maximum height is ...
f(1.5) = (-16·1.5 +48)1.5 +12 = (24·1.5) +12
f(1.5) = 48
The maximum height the object will reach is 48 feet.
Answer:
93 feet
Step-by-step explanation:
i graphed it and found the maximum
or, if you're not allowed to use a calculator then find the vertex
a = -16, b = 72, c = 12
-b/2a will give you the x-value of 9/4
now plug 9/4 into the equation to get the value of 'y'
= -16(9/4)² + 72(9/4) + 12
= -81 + 162 + 12
= 93

A : 20/100 = 18/ x
B : 18/20 = x/100
C : x/18 = 20/100
D : 20/x = 18/100
Answers
Answer:
C
Step-by-step explanation:
let's say the 18 was the 100 and x was the 20% of that 100, if they equal the same just take 20% of 18 (you will get 3.6)
Therefore is C : x/18 = 20/100.
