Answer:
a
[tex]A_w = 1.667 \ hour [/tex]
b
[tex]b = 0.667 \ hour [/tex]
Step-by-step explanation:
From the question we are told that
The mean number of ticket per hour is [tex]\mu = 12 \ tickets[/tex]
The mean number of customers arrive to purchase tickets each hour is [tex]\lambda = 8 \ customers[/tex]
Generally the average time the ticket buyer must wait is mathematically represented as
[tex]A_w = \frac{\lambda }{ \mu [\mu -\lambda]}[/tex]
=> [tex]A_w = \frac{8 }{ 12 [12-8]}[/tex]
=> [tex]A_w = 1.667 \ hour [/tex]
Generally the portion of time is the ticket seller busy is mathematically represented as
[tex]b = \frac{\lambda}{ \mu}[/tex]
=> [tex]b = \frac{8}{ 12} [/tex]
=> [tex]b = 0.667 \ hour [/tex]
corey tracks heart rate after coming off the ice in a hockey game. in 1/6 minute, her heart beats 26 times.
Answer:156
Step-by-step explanation: 26÷1/6 =26×6 =156
The intensity level is moderate
In one second Corey's heart will beat 3 times.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Corey's heart beats 26 times in 1/6 minutes.
Assume that her heart beats [x] times in 1 second. Then -
1/6 of minute = 1/6 x 60 = 10 seconds
In 10 seconds, her heart beats 26 times
So, in one second, her heart will beat (26/10) = 2.6 times = 3 times (approx.).
Therefore, in one second Corey's heart will beat 3 times.

What is R,S,W? I really need help!
Answer:
R- 73°
S- 73°
W- 138°
Step-by-step explanation:
Every triangle is 180°.
So 65+42=107
180-107=73
So that's the triangle to the right.
Now the other one is identical.
So we know the line w is on is 180°
On the corner w is on it took up 42°
So 180-42= 138° (which is 'w')

A superstar major league baseball player just signed a new deal that pays him a record amount of money. The star has driven in an average of 110 runs over the course of his career, with a standard deviation of 31 runs. An average player at his position drives in 80 runs. What is the probability the superstar bats in fewer runs than an average player next year
Answer:
0.1667
Step-by-step explanation:
Given that:
Average / mean runs (m) = 110 runs
Standard deviation (σ) = 31 runs
Number of runs driven in by an average player in his position = 80
The probability the superstar bats in fewer runs than an average player next year will be the :
P(x < 80)
Zscore = (x - mean) / σ
Zscore = (80 - 110) / 31
Zscore = - 30 / 31
Zscore = - 0.9677419
P(Z < 0.9677419) = 0.1666 ( from z probability calculator)
= 0.1667

Why might you need to use the addition or subtraction property of equality more than once after you have used the distributive property and combined like terms?
Answer:
If there is a variable term and a constant on each side of the equation, then you will need to use the addition or subtraction property of equality once to isolate the variable term and once to isolate the constant.

A pool measuring 8 meters by 24 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the pool and the path combined is 720 square meters, what is the width of the path? 8 + 2x 8 24 - 2x
The Width of the path is ____ meters
The real answer is 6
Step-by-step explanation:
the width of the path is 6 meters.
Let's assume the width of the path is represented by 'x' meters.
The overall dimensions of the combined pool and path would be:
Width = 8 + 2x
Length = 24 + 2x
To calculate the area of the combined pool and path, we multiply the width and length:
Area = (8 + 2x) * (24 + 2x)
Given that the area is 720 square meters, we can set up the equation:
(8 + 2x) * (24 + 2x) = 720
Expanding the equation:
192 + 16x + 48x + 4x² = 720
4x² + 64x + 192 = 720
Rearranging the equation:
4x² + 64x - 528 = 0
Now we can solve this quadratic equation either by factoring, completing the square, or using the quadratic formula. After solving the equation, we find that x = 6.
Therefore, the width of the path is 6 meters.

Caculate the unit rate using the following
information, mom drove 20 miles in 1/4 of an hour
What was her rate or spee in Miles per hour.
Answer:
80 miles per hour
Step-by-step explanation:
To find her speed in miles per hour, multiply 20 by 4.
Since she drove 20 miles in 1/4 of an hour, we can find the amount she can drive in 1 full hour by multiplying it by 4.
20(4)
= 80
So, her rate in miles per hour is 80 miles per hour
Answer:
80 mph
Step-by-step explanation:
20 miles multiplied by 4(quarters of the hour) is 80mph
