What is the equation of the line that passes through the points (- 2, 3) and (4, 1)
Answer:
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = ((- 2, 3) and (x₂, y₂ ) = (4, 1)
m = [tex]\frac{1-3}{4+2}[/tex] = [tex]\frac{-2}{6}[/tex] = - [tex]\frac{1}{3}[/tex] , thus
y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 3), then
3 = [tex]\frac{2}{3}[/tex] + c ⇒ c = 3 - [tex]\frac{2}{3}[/tex] = [tex]\frac{7}{3}[/tex]
y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{3}[/tex] ← equation of line

Is there a smallest decimal that is greater than the number 2? Explain your answer.
Answer:
Technically, yes. It's called epsilon, which is defined as an infinitely small number. So
2 + epsilon is the smallest number greater than 2. But for practical purposes no there isn't.
00
Step-by-step explanation:Not without limits. You can always move the .1 one place further from the interring. For example,
2.1>2.01
and
2.01>2.001
So, unless there are a limited number of decimal spaces, you can continually add an infinite amount of zeros behind the decimal point, followed by a one.
If you use two or three decimal spaces as a standard in your class, then the smallest decimal greater than 2 would be 2.01 or 2.001, respectively.

In a survey of 1,003 adults concerning complaints about restaurants, 732 complained about dirty or ill-equipped bathrooms and 381 complained about loud or distracting diners at other tables.
a. Construct a 95% confidence interval estimate for the population proportion of adults who complained about dirty or ill-equipped bathrooms )
b. Construct a 95% confidence interval estimate for the population proportion of adults who complained about loud or distracting diners at other tables.
c. How would the manager of a chain of restaurants use the results of (a) and (b)?
Answer:
a
[tex]0.716 < p < 0.744[/tex]
b
[tex]0.3498 < p < 0.4089[/tex]
c
With the result obtained from a and b the manager can be 95 % confidence that the proportion of the population that complained about dirty or ill-equipped bathrooms are within the interval obtained at a
and that
the proportion of the population that complained about loud or distracting diners at other tables are within the interval obtained at b
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n = 1003[/tex]
The number that complained about dirty or ill-equipped bathrooms is [tex]e = 732[/tex]
The number that complained about loud or distracting diners at other tables is [tex]q = 381[/tex]
Given that the the confidence level is 95% then the level of significance is mathematically represented as
[tex]\alpha = (100- 95)\%[/tex]
[tex]\alpha = 0.05[/tex]
Next we obtain the critical value of [tex]\frac{\alpha }{2}[/tex] from the normal distribution table , the value is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Considering question a
The sample proportion is mathematically represented as
[tex]\r p = \frac{e}{n}[/tex]
=> [tex]\r p = \frac{732}{1003}[/tex]
=> [tex]\r p = 0.73[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{ \r p (1- \r p)}{n} }[/tex]
[tex]E = 1.96* \sqrt{ \frac{ 0.73 (1- 0.73)}{1003} }[/tex]
[tex]E = 0.01402[/tex]
The 95% confidence interval is
[tex]\r p - E < p < \r p +E[/tex]
[tex]0.73 - 0.01402 < p < 0.73 + 0.01402[/tex]
[tex]0.716 < p < 0.744[/tex]
Considering question b
The sample proportion is mathematically represented as
[tex]\r p = \frac{q}{n}[/tex]
=> [tex]\r p = \frac{381}{1003}[/tex]
=> [tex]\r p = 0.3799[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{ \r p (1- \r p)}{n} }[/tex]
[tex]E = 1.96* \sqrt{ \frac{ 0.3799 (1- 0.3799)}{1003} }[/tex]
[tex]E = 0.0300[/tex]
The 95% confidence interval is
[tex]\r p - E < p < \r p +E[/tex]
[tex]0.3798 - 0.0300 < p < 0.3798 + 0.0300[/tex]
[tex]0.3498 < p < 0.4089[/tex]
You want to estimate the mean amount of time college students spend on the Internet each month. How many college students must you survey to be 95% confident that your sample mean
Answer:
752.95
Step-by-step explanation:
Data provided in the question
The standard deviation of population = 210
The Margin of error = 15
The confidence level is 75%, so the z value is 1.96
Now the required sample size is
[tex]= 1.96^2\times \frac{210^2}{15^2}[/tex]
= 752.95
Hence, the number of college students spends on the internet each month is 752.95

Complete the table shown below. f(x) = 2x2 - 8x + 6 1 0 2 y 3 4. 6 X= y = Z
Answer:
x = 6, y = -2, z = 0
Step-by-step explanation:
To find x, we have to plug 0 into f(x). Therefore, x = f(0) = 2 * 0² - 8 * 0 + 6 = 6. Similarly, to find y, we have to plug 2 into f(x) so y = f(2) = 2 * 2² - 8 * 2 + 6 = -2. Finally, z = f(3) = 2 * 3² - 8 * 3 + 6 = 0.

Give the largest interval over which the general solution is defined. (Think about the implications of any singular points. Enter your answer using interval notation.) Determine whether there are any transient terms in the general solution. (Enter the transient terms as a comma-separated list; if there are none, enter NONE.)
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
No singular point due to the exponent in the solution
The interval is [tex]-\infty <0 < \infty[/tex]
b
NONE
Step-by-step explanation:
From the question we are told that
[tex]\frac{dy}{dx} = 9y[/tex]
The generally solution is mathematically represented as
[tex]\frac{dy }{dx} = 9y[/tex]
=> [tex]\frac{dy}{y} = 9dx[/tex]
integrating both sides
[tex]\int\limits {\frac{ dy}{y} } \, = \int\limits {9} \, dx[/tex]
=> [tex]lny = 9x + c[/tex]
=> [tex]y = e^{9x +c }[/tex]
=> [tex]y = e^{9x} e^{c}[/tex]
Here [tex]e^c = C[/tex]
=> [tex]y = C e^{9x}[/tex]
From the above equation we see that the domain for x has no singular point the interval is
[tex]-\infty <0 < \infty[/tex]
Also there is no transient term in the general solution obtained because as [tex]x \to \infty[/tex] there no case where [tex]y \to 0[/tex]

Complete Question
A boat sails 4km on a bearing of 038 degree and then 5km on a bearing of 067 degree.(a)how far is the boat from its starting point.(b) calculate the bearing of the boat from its starting point
Answer:
a)8.717km
b) 54.146°
Step-by-step explanation:
(a)how far is the boat from its starting point.
We solve this question using resultant vectors
= (Rcos θ, Rsinθ + Rcos θ, Rsinθ)
Where
Rcos θ = x
Rsinθ = y
= (4cos38,4sin38) + (5cos67,5sin67)
= (3.152, 2.4626) + (1.9536, 4.6025)
= (5.1056, 7.065)
x = 5.1056
y = 7.065
Distance = √x² + y²
= √(5.1056²+ 7.065²)
= √75.98137636
= √8.7167296826
Approximately = 8.717 km
Therefore, the boat is 8.717km its starting point.
(b)calculate the bearing of the boat from its starting point.
The bearing of the boat is calculated using
tan θ = y/x
tan θ = 7.065/5.1056
θ = arc tan (7.065/5.1056)
= 54.145828196°
θ ≈ 54.146°
The average cost of a scientific calculator was $96.50 in 1970. The same type of calculator cost $21 in 2016. Assuming the exponential decay model applies, what will a similar calculator cost in the year 2019? Round your answer tbo the nearest cent.
Answer: the cost of a similar scientific calculate in 2019 will be $19.01
Step-by-step explanation:
Given that;
in 1970 cost of S.C = $96.50
in 2016 cost of same calculator = $21
In 2019 cost of a similar calculator = ?
Assuming the exponential decay model applies
dN/dt = -λN
we know that λ is the decay constant
⇒ N(t) = N₀e^-λt
N(t) is price at time t year, N₀ is initial price,
so t = 0 in 1970 thus N₀ = 96.50
also t = 46 in 2016 thus N₄₆ = 21
substituting into our initial expression
N(t) = N₀e^-λt
N(46) = N₀e^-λ×46
21 = 96.50e^-46λ ⇒ In 21/96.50 = -46λ
= -1.5250 = - 46λ
λ = -1.5250 / -46
λ = 0.03315
t = 0 in 1970 thus N₀ = 96.50
also t = 49 in 2019 thus N₄₉ = ?
so
using our initial expression again
N(49) = N₀ e^-49λ
= 96.5 × e^ (-49 × 0.03315 )
= 96.5 × 0.197014404
= 19.01189 ≈ 19.01
therefore the cost of a similar scientific calculate in 2019 will be $19.01

. Every month, there are 1000 independent TIE fighter flights, and each TIE fighter flight crashes with a probability of 0.0035. (a) What is the probability that at least 2 crashes occur in the next month
Answer:
[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]
Step-by-step explanation:
From the information given:
The probability that at least 2 crashes occurs in the next month can be estimated by using Poisson distribution because the sample size is large and the probability of the event p = 0.0035 is rare.
∴
Let X be the random variable that follows a Poisson distribution
The probability that at least 2 crashes occurs in the next month is:
[tex]\mathbf{P (X \geq 2) = 1 - P( X \leq 1) \sum \limits ^1_{x=0} ( ^{1000}_x) (0.0035)^x (0.9965)^{1000-x}}[/tex]

1: find the value of 8 4s. It’s not 84 but it’s 8 and then at the top it’s 4.
2: a mug is 1/7 full. The mug contains 1/3 of a cup of water. Find the capacity of the mug. Write the answer a fraction or mixed number in simplest form.
Problem 1
If you meant to say [tex]8^4[/tex], then you would have four copies of 8 multiplied together
[tex]8^4 = 8*8*8*8 = 4096[/tex]
==============================================
Problem 2
1/7 full = 1/3 cup of water
7*(1/7 full) = 7*(1/3 cup of water) ... multiply both sides by 7
1 full = 7/3 cup of water
So a full mug has 7/3 cups of water. Let's convert this to a mixed number
7/3 = (6+1)/3
7/3 = 6/3 + 1/3
7/3 = 2 + (1/3)
7/3 = 2 & 1/3
The full capacity of the cup is 7/3 cups or 2 & 1/3 cups
7/3 is the improper fraction form
2 & 1/3 is the mixed number form
One way to think of it is to imagine there are 7 cookies and you want to distribute among 3 friends. We could say 7/3 = 2 remainder 1 meaning each person gets 2 full cookies and there's 1 left over. So that's how we'd get 2 & 1/3.
