3) -2/9 is the right answer.A boat takes 2 hours to travel 15 miles upriver against the current. If the rate of the boat in still water is 13 miles per hour what is the rate of the current?
Answer:
The rate of the current is 5.5 miles per hour
Step-by-step explanation:
Relative Speeds
The boat takes 2 hours to travel 15 miles upriver against the current. The speed is 15/2 = 7.5 miles per hour.
Since the boat in still water can travel at 13 miles per hour, it means the current subtracts its speed from the speed of the boat:
Vcurrent = 13 mi/h - 7.5 mi/h
Vcurrent = 5.5 mi/h
The rate of the current is 5.5 miles per hour

Answer:
Solve the scientific Calculator
find the slope given the points (3 2) and (4 7)
Answer:
5
Step-by-step explanation:
slope = (y₂ - y₁) / (x₂ - x₁)
= (7 - 2) / (4 - 3)
= 5 / 1
= 5
The slope of the line passing through the points (3 2) and (4 7) is 5
The formula for calculating the slope of a line passing through the point (3 2) and (4 7) is expressed as:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{7-2}{4-3}\\m=\frac{5}{1} \\m=5[/tex]
Hence the slope of the line passing through the points (3 2) and (4 7) is 5

The cube of y varies directly as z. When y = 8, z = 8. Heather’s work finding the value of y when z = 64 is shown:
y^3 = kz
8 = k x 8
1 = k
y^3 = 1 x 64
y^3 = 64
y = 4
What is the first error, if any, in Heather’s work?
A. She did not make any errors.
B. She substituted incorrectly when calculating the constant of variation.
C. She cubed the wrong variable when making her equation.
D. She used an equation that models inverse variation instead of direct variation.
Answer:
Step-by-step explanation:
If the cube of y varies directly as z, then;
y³ ∝ z
y³ = kz
k is the constant of proportionality
y³ = kz
When y = 8, z = 8.
8³ = 8k
k = 8³ /8
k = 64
To get the value y when z = 64, we will have;
y³ = kz
y³ = 64(64)
y³ = 4096
y= ∛4096
y = 16
Hence the value of y is 16

Answer:
a)
Growth rate 0.075
Growth factor 1.075
b) 59177 or approx 60000
Step-by-step explanation:
I love these kind of question where we get to model equations :D So lets get started.
a)
The population of a city after t years after 2010 is given by
[tex]P=20000(1.075)^t[/tex]
The original exponential growth formula is:
[tex]y=a(1+r)^t[/tex]
so we can write our equation in this form as well:
[tex]P=20000(1+0.075)^t[/tex]
the growth factor is 1+r which is 1+0.075 which is 1.075
the growth rate is determined by the value of r which is 0.075
b)
Since our equation represents the population of a city after the year 2010 we can use it to further calculate the population in 2025 so
2025 - 2010 = 15
we set the value of t in our equation to 15 which is in years,
[tex]P=20000(1.075)^{15}\\P=59177[/tex]
so we can say that our population in 2025 would be approximately 60,000
The average price of a 30 second commercial for the 2002 Super Bowl was $1,900,000. What was the price per second?
Answer:
$63,333.33
Step-by-step explanation:
Divide 1,900,000 by 30 to get $63333.3333....which technically just rounds to $63333.33, and if you want to go further, $63333.

a) Using Long Division show your work.
(-6x – 5 + x4 + 4x3) - (x2 – 8)
Answer:
its 85
Step-by-step explanation:
The time needed for all college students to complete a certain paper-and-pencil maze follows a normal distribution with a population mean of 30 seconds and a population standard deviation of 3 seconds.
You wish to see if the mean time μ (where μ stands for population mean) is changed by vigorous exercise, so you have a group of nine college students exercise vigorously for 30 minutes and then complete the maze. It takes them an sample average of 31.2 seconds to complete the maze. Use this information to test the hypotheses:
H0: μ = 30,
Ha: ≠30
at the significance level of 0.01.
You conclude:
a) There is not enough evidence to support the claim.
b) There is enough evidence to support the claim.
Answer:
The correct option is a
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 30\ seconds[/tex]
The standard deviation is [tex]\sigma = 3 \ seconds[/tex]
The sample size is n = 9
The null hypothesis is [tex]H_o: \mu = 30[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 30[/tex]
The level of significance is [tex]\alpha = 0.01[/tex]
The sample mean is [tex]\= x = 31.2[/tex]
Generally the test statistics is mathematically represented as
[tex]z = \frac{ \= x - \mu }{ \frac{\sigma}{\sqrt{n} } }[/tex]
=> [tex]z = \frac{ 31.2 - 30}{ \frac{3}{\sqrt{9} } }[/tex]
=> [tex]z = 1.2[/tex]
From the z table the area under the normal curve to the right corresponding to 1.2 is
[tex]P(Z > 1.2) = 0.11507[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > 1.2)[/tex]
=> [tex]p-value = 2 *0.11507[/tex]
=> [tex]p-value = 0.230[/tex]
From the value obtained w can see that
[tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is there is not enough evidence to support the claim

Answer:
Since it is multiplied by ten, its basically multiplying 8.88 by 1 and moving the decimal to the right once. Multiplying numbers by 10s, 100s etc. means you have to shift the decimal point to the right based on a number of zeros multiplied.
