Three types of tickets for a football game are available: sidelines, goal-view, and upper-deck. The sidelines tickets cost $25 more than the goal-view tickets and $50 more than the upper deck tickets. The goal-view tickets cost $13 less than twice the cost of the upper-deck tickets. Determine the price of each type of ticket.
Answer:
Upper deck = $38
Goal View = $63
Sidelines = $88
Step-by-step explanation:
Represent
- Sidelines with S
- Goal-view with G
- Upper-deck with U
We have that:
[tex]S = 25 + G[/tex]
[tex]S = 50 + U[/tex]
[tex]G = 2U - 13[/tex]
Required
Solve for S, G and U
Substitute 25 + G for S in the second equation
[tex]25 + G = 50 + U[/tex]
Make G the subject
[tex]G = 50 -25+ U[/tex]
[tex]G = 25+ U[/tex]
Substitute 25 + U for G in the third equation
[tex]25 + U = 2U - 13[/tex]
Collect Like Terms
[tex]U - 2U = -13 - 25[/tex]
[tex]-U = -38[/tex]
[tex]U = 38[/tex]
Substitute 38 for U in [tex]G = 25+ U[/tex]
[tex]G = 25 + 38[/tex]
[tex]G =63[/tex]
Substitute 63 for G in [tex]S = 25 + G[/tex]
[tex]S = 25 + 63[/tex]
[tex]S = 88[/tex]

Cathy bough treats at her local bakery the past two weeks. The first week she bought 6 donuts and 3 muffins and paid $42. The second week she bought 3 donuts and 2 muffins and paid $24. How much does it cost for each donut and each muffin?
Answer:
Donuts are $4 and Muffins are $6
Step-by-step explanation:
Start by setting up both equations:
6d+3m=42
3d+2m=24
Then multiply the second equation by -2:
-6d-4m=-48
Then subtract the second equation by the first:
6d+3m=42
-6d-4m=-48
The sixes will cancel out and you'll have the equation:
-m=-6 or m=6
This tells you that each muffin is $6
Then you want to plug in six for m in one of the original equations:
3d+2(6)=24
Then solve for d:
3d+12=24
3d=12
d=4
This tells you that each dount is $4

In ΔRST, t = 4.1 inches, r = 7.1 inches and ∠S=45°. Find the length of s, to the nearest 10th of an inch.
Answer:
The length of s is 5.1 inches to the nearest tenth of an inch
Step-by-step explanation:
In Δ RST
∵ t is the opposite side to ∠T
∵ r is the opposite side to ∠R
∵ s is the opposite side to ∠S
→ To find s let us use the cosine rule
∴ s² = t² + r² - 2 × t × r × cos∠S
∵ t = 4.1 inches, r = 7.1 inches, and m∠S = 45°
→ Substitute them in the rule above
∴ s² = (4.1)² + (7.1)² - 2 × 4.1 × 7.1 × cos(45°)
∴ s² = 16.81 + 50.41 - 41.1677568
∴ s² = 26.0522432
→ Take √ for both sides
∴ s = 5.10413981
→ Round it to the nearest tenth
∴ s = 5.1 inches
∴ The length of s is 5.1 inches to the nearest tenth of an inch

Suppose a particular brand of energy bars has come up with a new recipe. They want to know how many energy bars they need to test for calorie content in order to be 94% confident that the sample mean will be within 3 calories of the true mean
Complete Question
Suppose a particular brand of energy bars has come up with a new recipe. They want to know how many energy bars they need to test for calorie content in order to be 94% confident that the sample mean will be within 3 calories of the true mean? Suppose there is a population standard deviation of 20 calories
Answer:
The value is [tex]n =157 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is [tex]E = 3[/tex]
The standard deviation is [tex]\sigma = 20[/tex]
From the question we are told the confidence level is 94% , hence the level of significance is
[tex]\alpha = (100 - 94 ) \%[/tex]
=> [tex]\alpha = 0.06[/tex] \
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.881[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2[/tex]
=> [tex]n = [\frac{1.881 } * 20 }{3} ] ^2[/tex]
=> [tex]n =157 [/tex]

Answer:
a. 0.45 customers
b. 0.0145 hours
c. 1.05 customers
Step-by-step explanation:
Missing word "A vending machine dispenses hot chocolate or coffee. service time is 30 seconds per cup and is constant. customers arrive at a mean rate of 72 per hour, and this rate is Poisson-distributed."
λ = 72 customers per hours
μ = 120 customers per hours
a. Lq = λ²/ 2μ(μ-λ)
Lq = 72² / 2(120)(120-72)
Lq = 9/20
Lq = 0.45 customers
b. Ws = Wq + 1/μ = Lq/λ + 1/μ
Ws = 9/20 customers/72 customers + 1/120 customers
Ws = 0.0145 hours
c. Ls = Lq + r
Ls = 9/20 + 72/120
Ls = 1.05 customers

An insurance company checks police records on 582 accidents selected at random and notes that teenagers were at the wheel in 91 of them. Which is a correct 90% confidence interval for the proportion of all auto accidents that involve teenage drivers
Answer:
The 90% confidence interval is [tex]0.1316 < p < 0.1812[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 582
The number of teenagers at the wheel is k = 91
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{91}{582}[/tex]
=> [tex]\^ p = 0.1564[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.645 * \sqrt{\frac{0.1564 (1- 0.1564)}{582} } [/tex]
=> [tex]E = 0.0248 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.1564 -0.0248 < p < 0.1564 + 0.0248[/tex]
=> [tex]0.1316 < p < 0.1812[/tex]
Which of the following is an accurate description of the scatterplot?
A. The more seeds that are planted per square foot the smaller the expected yield of the crop.
B. the more seeds that are planted per square foot the larger the expected yield of the crop.
C. The expected yield of a crop is high whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square is around 60.
D.The expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square is around 60.
Answer:
WARNING! THE PERSON ABOVE ME IS WRONG!
A is incorrect, it does NOT decrease, it goes in a parabola.
This makes (D) the correct answer.
The expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square is around 60.
D.The expected yield of a crop is low whenever the number of seeds planted per square foot is small or large.
A larger yield is expected when the number of seeds per square is around 60.
What is a scatterplot?A scatter plot is a particular kind of plot or mathematical diagram that displays values for typically two variables for a collection of data.
It uses Cartesian coordinates. A second variable can be shown if the points are coded.
Here x coordinate represents the no. of seeds planted per square foot and the y coordinate represents crop yield per square foot.
If we observe the given scatterplot we see that before and after 60 seeds planted per square foot crop yield decreases.
∴ Every time there are few or many seeds planted per square foot, the crops predicted yield is poor. When there are about 60 seeds per square, a greater yield is anticipated.
