The scatter plot shows the average price of a major-league baseball ticket from 1997
to 2006.
Use the points (2001, 17.60) and (2002, 18.75) to write the slope-intercept form of equation for the line of fit Baseball Ticket Prices shown in the scatter plot.
Line of Fit:_________
b. Use your equation to tell the price of a ticket in 2009. Is this extrapolation or interpolation?
Answer:
a) y = [tex]\frac{23}{20}[/tex] x + 13
b) ticket price in 2009 would be $23.35 by extrapolation

help me! I have a retake on this and my last answer I put was A and D and I got it wrong!
9514 1404 393
Answer:
A, E
Step-by-step explanation:
You are correct that the appropriate relationship is ...
g = 0.4t . . . . choice A
You are also correct that an equivalent relationship is ...
t = 2.5g . . . . choice D
However, when we say gallons are proportional to seconds, we usually expect that to be written ...
g = kt . . . . for some value of k
__
We note that another equivalent is ...
g = 2/5t . . . . choice E
The appropriate choices are probably A and E. Choice D might be argued to be correct, but you could very well lose that argument to someone who prefers a "g = " form of the relationship.
A person places $3090 in an investment account earning an annual rate of 3%,
compounded continuously. Using the formula V = Pet, where V is the value of the
account in t years, P is the principal initially invested, e is the base of a natural
logarithm, and r is the rate of interest, determine the amount of money, to the
nearest cent, in the account after 11 years.
Answer:
$4298.10
Step-by-step explanation:
Using the relation :
V = Pe^rt
P = 3090 ; r = 3% = 0.03 ; t = 11 years
V = 3090 * e^(0.03 * 11)
V = 3090 * e^0.33
V = 3090 * 1.3909681
V = 4298.0915
Amount in the investment after 11 years will be $4298.10
How many solutions does the system of linear equations represented in the graph below have?
A
No Solution
B
One Solution
C
Infinitely many solutions
D
None of the above
Answer:
No solution
Step-by-step explanation:
They must intersect to have one solution. For infinite many solutions, the lines would be on top of each other.
Determine whether y= 1 is a solution to 10 = y-9.
Answer:
y = 19
Step-by-step explanation:
19-9=10
y = 19
No, it cannot equal one because if it did the answer would be -8. If you add 10 and 9 it is equal to 19, which means that y=19.
Find the distance between the given points. Round to the nearest tenth. 5,-2 and 1,2.
Answer:
[tex]4\sqrt{2}[/tex]
Step-by-step explanation:
Use the distance equation
[tex]\sqrt{(x1-x2)^2+(y1-y2)^2}[/tex]
insert values (5,-2)=(x1,y1) and (1,2)=(x2,y2)
[tex]\sqrt{(5-1)^2+((-2)-2)^2}[/tex]
[tex]\sqrt{16+16}[/tex]
[tex]4\sqrt{2}[/tex]

Hanna wants to estimate the number of eels in a lake
Debbie has $460 in a savings account that earns 8% simple interest annually. How much interest will she earn in 5 years?
Answer:
Hello! The interest would be $184. You would have to use the formula
I= P x r x t. I would equal interest, p is principal amount, r is interest rate and t is the time involved which is 5 years. But first you have to divide 8% by 100 which is 0.08. 460 x 0.08 x 5= $184

In ΔBCD, the measure of ∠D=90°, the measure of ∠B=22°, and DB = 44 feet. Find the length of BC to the nearest tenth of a foot.
Answer: 47.5 ft
Step-by-step explanation:
since this is a right triangle, you can use trig to solve for x:
cos 22° = [tex]\frac{44}{x}[/tex] (cos = adjacent/hypotenuse)
x * cos 22° = 44
x = [tex]\frac{44}{cos 22}[/tex] (plug into calc)
x = 47.5 ft

closest to the volume of
the cone in cubic
kilometers?
7 km
14 km
781.3 km
O 435.1 km
O 562.4 km
718.4 km
Answer:
A) 781.3
Step-by-step explanation:
To find the volume of the cone, you must first find the radius and height of the cone. Which is 7km (radius) and 14km(height).
Next use the formula (Which is in the picture since it's too hard to type out on here)
I also would of explained it but I found it easier just to type it out (In the file attached below)
Finally the answer is 781.3 km

Answer: [tex]y=2.75x+7.5[/tex], 10 miles
Step-by-step explanation:
Given
The company charges $2.75 per mile
The total charge is $29.50
Also, x represents the number of miles and y represents the total cost of the cab ride
Assume extra charge be c
for 8 miles, the charge is
[tex]\Rightarrow 29.50=2.75\times 8+c\\\Rightarrow c=\$7.5[/tex]
The slope-intercept form of the information is
[tex]\Rightarrow y=2.75x+7.5[/tex]
for $35 charge, miles covered
[tex]\Rightarrow 35=2.75x+7.5\\\Rightarrow 2.75=27.5\\\Rightarrow x=10\ \text{miles}[/tex]

pyramid A: 16 + [tex]8\sqrt{5[/tex]
pyramid B: 400 + [tex]8\sqrt{125[/tex]
pyramid A: 4 by 4= 16 cm.
with a height of 1 and length of 2, we use pythagorean theorem to find height of other surfaces to be square root of 5. area of triangle is 1/2 bh
square root of 5 multiplied by 4 and divided by 2 is 2 root 5
multiply this by 4 sides total for 8 root 5
Add the 8 root 5 to 16
To find pyramid B: use ratio of 25:1 and multiply 16 by 25 to find 400, and root 5 to 125
Which graph shows exponential growth?
Answer:
VTFV
Step-by-step explanation:
The authors of a paper concluded that more boys than girls listen to music at high volumes. This conclusion was based on data from independent random samples of 768 boys and 745 girls from a country, age 12 to 19. Of the boys, 397 reported that they almost always listen to music at a high volume setting. Of the girls, 331 reported listening to music at a high volume setting.
Do the sample data support the authors' conclusion that the proportion of the country's boys who listen to music at high volume is greater than this proportion for the country's girls? Test the relevant hypotheses using a 0.01 significance level. (Use a statistical computer package to calculate the P-value. Use μboys − μgirls. Round your test statistic to two decimal places and your P-value to four decimal places.)
Answer:
Since the calculated value of z= 2.82 does not lie in the critical region the null hypothesis is accepted and it is concluded that the sample data support the authors' conclusion that the proportion of the country's boys who listen to music at high volume is greater than this proportion for the country's girls.
The value of p is 0 .00233. The result is significant at p < 0.10.
Step-by-step explanation:
1) Let the null and alternate hypothesis be
H0: μboys − μgirls > 0
against the claim
Ha: μboys − μgirls ≤ 0
2) The significance level is set at 0.01
3) The critical region is z ≤ ± 1.28
4) The test statistic
Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]
Here p1= 397/768= 0.5169 and p2= 331/745=0.4429
pc = 397+331/768+745
pc= 0.4811
qc= 1-pc= 1-0.4811=0.5188
5) Calculations
Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]
z= 0.5169-0.4429/√ 0.4811*0.5188( 1/768+ 1/745)
z= 2.82
6) Conclusion
Since the calculated value of z= 2.82 does not lie in the critical region the null hypothesis is accepted and it is concluded that the sample data support the authors' conclusion that the proportion of the country's boys who listen to music at high volume is greater than this proportion for the country's girls.
7)
The value of p is 0 .00233. The result is significant at p < 0.10.

Ella has a part-time job selling cupcakes at a cart in the park. She is paid $25 for a shift plus a fee of $0.25 for each cupcake she sells. A) Write and equation that can be used to solve for the total amount, t, Ella earns for working a shift in the park and selling c cupcakes. Ella works a shift and earns $38. B. Use the equation you wrote for part A to solve for the number of cupcakes Ella sold during her shift. Show your work. In the summer, the average number of cupcakes sold during a weekday shift is 36 and the average number of cupcakes sold during a weekend shift is 62. Ella has been given the choice to work a regular schedule of 3 weekday shifts each week or 2 weekend shifts each week. C. Explain which schedule will allow Ella to earn $300 more quickly. Support your answer with mathematical evidence, and state which shift Ella should choose.
9514 1404 393
Answer:
A) t = 0.25c +25
B) c = 52
C) 3 weekday shifts
Step-by-step explanation:
A. The amount Ella earns is $0.25 per cupcake, so for c cupcakes, that is ...
0.25c
In addition, she is paid $25, so her total amount she is paid is ...
t = 0.25c +25
__
B. In order to earn $38, the number of cupcakes sold must be ...
38 = 0.25c +25
13 = 0.25c . . . . . . subtract 25
52 = c . . . . . . . . . multiply by 4
Ella sold 52 cupcakes to earn $38.
__
C. On one of the average weekdays, Ella could be expected to earn ...
t = 0.25(36) +25 = 34
Then for 3 weekday shifts, her earnings would be 3($34) = $102. (It would take Ella 3 weeks to earn $300.)
On one of the average weekend shifts, Ella could be expected to earn ...
t = 0.25(62) +25 = 40.50
Then for 2 weekend shifts, her earnings would be 2($40.50) = $81. (It would take Ella 4 weekends to earn $300.)
Ella would earn $300 more quickly by working weekday shifts.
