Answer:
a) linear function = 150 + 30x represents 1km
and 150 + 60x represents 2km We can therefore remove the ones and even factor 15 and 3 into
3(5+1x)
b) y = 2/3x + 225
Can be factored from 2/3 (30x+75) and simplified to 2/3(3x+15/2)
Step-by-step explanation:
if 150 stop and 30 for each mile
we show zero on each axis and show the y intercept at 150
The X axis should determine time or distance travelled
So if showing distance we show miles in 10,20,30,40,
and costs 0,30,60,90 but if 150 applies to any passengers entering vehicle and all journeys then we start graph at $ cost = 150 and go up by 30 showing 150.180.210.240 for the data for the y axis/
Therefore 20k is 2/3 km and we can show 2/3 as our multiple.
2/3 of 225 is 150 to find we flip 3/2 x 150 = 225
y = 2/3 ( 30x + 225) and we have our equation for b
y = 2/3x + 225

Find the surface area of a regular square pyramid with a base edge length
of 9 feet and a slant height of 12 feet.
Answer:
Perimeter = 9 . 4=36 ft
lateral area=(perimeter . slant height) / 2 = (36 . 12) /2 = 216 sq ft
area of the base=9*9=81 sq ft
Surface area = LA+BA = 216 + 81 = 297 sq ft

The following data are the monthly salaries y and the grade point averages x for students who obtained a bachelor's degree in business administration.
GPA Monthly Salary ($)

3.4 3,800
3.6 4,200
3.1 3,700
3.4 4,200
3.1 2,500
The estimated regression equation for these data is = 2090.5 + 581.1x and MSE = 21,284.
Required:
a. Develop a point estimate of the starting salary for a student with a GPA of 3.0
b. Develop a 95% confidence interval for the mean starting salary for all students with a 3.0 GPA (to 2 decimals).
c. Develop a 95% prediction interval for Ryan Dailey, a student with a GPA of 3.0 (to 2 decimals).
Answer:
1.) 3833.8
2.) (3428.81 ; 4238.79)
Step-by-step explanation:
1.)
Point estimate of the salary for student with GPA of 3.
Using the regression model given :
Y = 2090.5 + 581.1x
x = 3
Y = 2090.5 + 581.1(3)
= 3833.8
2.)
95% confidence interval :
Y ± Tcritical * √MSE
Y = point estimate at x =3 ; = 3833.8
MSE = 21,284
Tcritical at 95% ; df = n-2 = 6-2 = 4
Tcritical(0.025 ; 4) = 2.776
√MSE = √21284 = 145.89036
Lower boundary : 3833.8 - 2.776(145.89036) = 3428.81
Upper boundary : 3833.8 + 2.776(145.89036) = 4238.79
(3428.81 ; 4238.79)

Answer:
Option A.
(x + 8) + (–4x + 31) / (x² + 2x + 1)
Step-by-step explanation:
x³ + 10x² + 13x + 39 / x² + 2x + 1
To rewrite the above expression in the form q(x) + r(x) / b(x), we shall simply divide (x³ + 10x² + 13x + 39) by
(x² + 2x + 1)
Please see attached photo for explanation
From the attached photo,
the quotient q(x) = x + 8
The remainder r(x) = –4x + 31
Divisor b(x) = x² + 2x + 1
Thus,
x³ + 10x² + 13x + 39 / x² + 2x + 1
= (x + 8) + (–4x + 31) / (x² + 2x + 1)

The area of the region under the curve of a function f(x) = ax + b on the interval [0, 4] is 16 square units.
(a, b) can't equal
The area of the given region under the curve of a function f(x) = ax + b on the interval [0, 4] is 16 square units. So, all the options satisfy the value of a and b except (7, -9).
How to find the area of a region?Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly.
Then summing all those pieces' area gives us the area of the main big region.
The area of the given region under the curve of a function f(x) = ax + b on the interval [0, 4] is 16 square units.
f(x) is a linear function, the area under the curve on the interval [0,4] is a trapezoid with a height of 4 and bases of lengths f(0) and f(4).
The area of a trapezoid is the height times the average of the bases.
a. f(x)=-2x+8 f(0)=8, f(4)=0;
area = 4(8/2) = 16
b. f(x)=x+2; f(0)=2, f(4)=6;
area = 4(8/2) = 16
c. f(x)=3x-2; f(0)=-2, f(4)=10;
area = 4(8/2) = 16
d. f(x)=5x-6; f(0)=-6, f(4)=14;
area = 4(8/2) = 16
e. f(x)=7x-9; f(0)=-9, f(4)=19;
area = 4(10/2) = 20
Thus, The area is NOT 16 for choice e.

mZR = 110 and mZS = 80. Find mZT. The diagram is not to scale.
Answer:
d. 90°
Step-by-step explanation:
Recall: based on the properties of a kite, the angles where the two unequal sides meet are congruent, this means that m<S = m<U.
Also, the sum of all angles of a kite = 360°
Therefore:
m<S + m<U + m<R + m<T = 360°
m<S = m<U = 80°
m<R = 110°
Substitute
80° + 80° + 110° + m<T = 360°
270° + m<T = 360°
Subtract 270° from each side
m<T = 360° - 270° = 90°

Step-by-step explanation:
We solve the equation the following way...
[tex]\frac{1}{5}6x - 3 = \frac{1}{10}(6x + 12)\\1.2x = 0.6x + 1.2 + 3\\1.2x - 0.6x = 1.2 + 3\\0.6x = 4.2\\6x = 42\\x = 7[/tex]
The average score of 100 students taking a statistics final was 70 with a standard deviation of 7. Assuming a normal distribution, what test score separates the top 5% of the students from the lower 95% of students?
Answer:
Hence, the answer is [tex]x>71.1515[/tex]
Step-by-step explanation:
We have,
[tex]n=100,\mu=70,\sigma=7[/tex]
The top percentage of the students is [tex]5\%[/tex]
The lower percentage of the students is [tex]95\%[/tex]
The lowest [tex]95\%[/tex] is the left area from the normal distribution table, the area [tex]0.95[/tex] lies in the z-table
[tex]z=1.645[/tex] from the z- table
[tex]P(z<1.645)=0.95\\P(z>1.645)=0.05\\z>1.645[/tex]
[tex]\frac{x-\mu}{\frac{\sigma}{\sqrt{\mu}} } >1.645\\x>1.645\times \frac{\sigma}{\sqrt{n}} +\mu[/tex]
[tex]>1.645\times \frac{7}{\sqrt{100}} +70[/tex]
[tex]\Rightarrow x>71.1515[/tex]

Approximately how many square meters does the field cover? Use pi = 3.14.
9514 1404 393
Answer:
4041 m²
Step-by-step explanation:
The area is the sum of the areas of the circle and the central rectangle.
A = πr² + LW
A = (3.14)(18 m)² + (36 m)(84 m) = 1017.36 m² +3024 m²
A = 4041.36 m²
The field covers about 4041 square meters.

Two sides of a parallelogram are 730 feet and 970 feet. The measure of the angle between these sides is 151°. Find the area of the parallelogram to the nearest square foot.
Answer:
343294 feets
Step-by-step explanation:
We Obtian the height:
Using trigonometry :
Sin151 = h / 730
0.4848096 = h / 730
h = 353.91102
Area of parallelogram = base * height
Base = 970 feets ; height = 353.91102 feets
Area = 970 * 353.91102
= 343293.6894 feets
= 343294 feets
