5. A theater wants to take in at least $2000 for the matinee. Children's
tickets cost $5 each and adult tickets cost $10 each. The theater can seat
up to 350 people. Select all the combinations of children and adult tickets
that will make the $2000 goal.
There are several possible answers.
A- (80, 150)
B- (40, 200)
C- (60, 150)
D- (70, 160)
E- (90, 200)
F- (200, 100)
The required number of children and adults for sitting in the theater are 300 and 50 respectively.
Explain linear equation of two variable.A equation is supposed to be linear equation in two factors in the event that it is written as hatchet + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an a and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are straight equation in two factors.
According to question:Let be consider number of children be x and that of adults is y.
We have,
x + y = 350-------(1)
y = 350 - x
And 5x + 10y = 2000------------------(2)
Put value of y in equation (2)
5x + 10( 350 - x) = 2000
5x + 3500 - 10x = 2000
-5x = -1500
x = 300
Then
y = 350 - x = 350 - 300 = 50
Thus, There will be 300 children and 50 adults in the theater .

3. Kai Hayashi owns 60 shares of Comerica Inc. for which he
paid $3,945.90, including a commission of $113.40. Comerica
pays annual dividends of $1.92.
a. What was the cost per share?
b. What is the annual yield?
The Annual yield is approximately 2.92%.
To determine the cost per share and the annual yield, we need to perform some calculations based on the given information.
a. Cost per share:
The cost per share can be calculated by dividing the total cost (including the commission) by the number of shares.
Total cost = Cost of shares + Commission
Total cost = $3,945.90
Number of shares = 60
Cost per share = Total cost / Number of shares
Cost per share = $3,945.90 / 60
Cost per share ≈ $65.76
Therefore, the cost per share is approximately $65.76.
b. Annual yield:
The annual yield is the dividend per share divided by the cost per share, expressed as a percentage.
Dividend per share = $1.92
Annual yield = (Dividend per share / Cost per share) * 100
Annual yield = ($1.92 / $65.76) * 100
Annual yield ≈ 2.92%
Therefore, the annual yield is approximately 2.92%.
In summary:
a. The cost per share for Comerica Inc. is approximately $65.76.
b. The annual yield for Comerica Inc. is approximately 2.92%.

this is a graphing problem and I am trying to figure out what the x-intercepts and the y-intercepts are. "Pleas show the steps"
Answer:
x- intercept = 4 , y- intercept = - 2
Step-by-step explanation:
To find the x- intercept let f(x) = 0 , that is
\(\frac{x-4}{-x+2}\) = 0
The denominator cannot be zero as this would make f(x) undefined
Equating the numerator to zero
x - 4 = 0 ⇒ x = 4 ← is the x- intercept
To find the y- intercept let x = 0 , that is
f(0) = \(\frac{0-4}{-0+2}\) = \(\frac{-4}{2}\) = - 2 ← is the y- intercept

Consider the following observations on a receptor binding measure (adjusted distribution volume) for a sample of 13 healthy individuals: 22, 39, 40, 42, 43, 46, 51, 57, 64, 65, 68, 69, 72. Predict the adjusted distribution volume of a single healthy individual by calculating a 95% prediction interval.
The 95% prediction interval for the adjusted distribution volume of a single healthy individual is approximately 12.03 to 76.89.
To calculate a 95% prediction interval for the adjusted distribution volume of a single healthy individual based on the given data, follow these steps:
1. Calculate the mean (µ) and standard deviation (σ) of the sample:
Mean (µ) = (22+39+40+42+43+46+51+57+64+65+68+69+72) / 13 = 578 / 13 = 44.46
Standard deviation (σ) = √(Σ(x-µ)² / (n-1)) = 15.15 (approx.)
2. Find the t-value corresponding to a 95% prediction interval for 12 degrees of freedom (n-1) from a t-distribution table or calculator (e.g., online t-table or calculator). The t-value for 12 degrees of freedom and 95% prediction interval is 2.179 (approx.).
3. Calculate the prediction interval using the following formula:
Prediction interval = µ ± t * σ * √(1 + (1/n))
Prediction interval = 44.46 ± 2.179 * 15.15 * √(1 + (1/13))
4. Compute the final values:
Lower bound: 44.46 - 2.179 * 15.15 * √(1 + (1/13)) = 12.03 (approx.)
Upper bound: 44.46 + 2.179 * 15.15 * √(1 + (1/13)) = 76.89 (approx.)

g(x) has the greatest x-intercept.
Option(A) is correct.
What is the x-intercept of the function?
To find the x-intercept of a function, we set y = 0 and solve for x. The x-intercept is the point where the graph of the function intersects the x-axis.
To find the x-intercept of a function, we set y = 0 and solve for x.
For g(x) = 3/2 * x + 1, setting y = 0 gives:
0 = 3/2 * x + 1
Solving for x:
x = -2/3
So the x-intercept of g(x) is -2/3.
For h(x), there is no x-intercept because all the y-values are negative.
For f(x), setting y = 0 gives:
0 = 3/2 * x + 1
Solving for x:
x = -2/3
So the x-intercept of f(x) is also -2/3.
For j(x), we don't have enough information to determine the function. Therefore, we cannot compare it with the other functions in terms of x-intercepts.
So, between g(x), h(x), and f(x), the function with the greatest x-intercept is g(x) because it has an x-intercept of -2/3, which is larger than the x-intercepts of f(x) and h(x).
Hence, g(x) has the greatest x-intercept.
Option(A) is correct.

c. To differentiate e^(-BQ) with respect to Q, we use the chain rule. The derivative is dp/dQ = -B * e^(-BQ).
The log-linear demand for a product can be expressed as ln(Q) = -BQ, where Q represents the quantity demanded and B is a constant coefficient. In order to find the relationship between price (p) and quantity (Q) and calculate the derivative dp/dQ, let's follow the steps below:
a. Express Q as a function of p:
To find the relationship between Q and p, we need to exponentiate both sides of the equation ln(Q) = -BQ. This gives us:
Q = e^(-BQ).
Now, we can solve for Q in terms of p by substituting p for Q:
p = e^(-Bp).
To calculate dp/dQ, we differentiate the expression with respect to Q:
dp/dQ = d/dQ(e^(-BQ)).
b. Express p as a function of Q and find dp/dQ:
To express p as a function of Q, we start with the equation p = e^(-Bp) and solve for p:
p = e^(-BQ).
To find dp/dQ, we differentiate the expression with respect to Q:
dp/dQ = d/dQ(e^(-BQ)).
c. Show mathematical steps for differentiation:
To differentiate e^(-BQ) with respect to Q, we can use the chain rule. Let's denote f(Q) = e^(-BQ), then:
df/dQ = (df/dQ)(dQ/dQ) = (d/dQ(e^(-BQ))) * 1 = -B * e^(-BQ).

let f(x) = x[infinity] n=1 x n n2 . find the interval of convergence for f. (Enter your answers using interval notation.)
Find the intervals of convergence for f?'.
Find the intervals of convergence for f?''.
The intervals of convergence for f'(x) are (-1, 1).
The intervals of convergence for f''(x) are (-1, 1).
To find the interval of convergence for the function f(x) = Σ(xⁿ/n²), where the summation is from n = 1 to infinity, we can use the ratio test.
The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. Mathematically, the ratio test can be written as:
lim |(a[n+1] / a[n])| < 1
Let's apply the ratio test to f(x):
f(x) = x + x²/2² + x³/3² + x⁴/4² + ...
First, let's calculate the ratio of consecutive terms:
|r| = |(x⁽ⁿ⁺¹⁾ / (n+1)²) / (xⁿ / n²)|
= |(x⁽ⁿ⁺¹⁾ × n²) / ((n+1)² × xⁿ)|
= |x × (n² / (n+1)²)|
Taking the limit as n approaches infinity:
lim |x × (n² / (n+1)²)|
= |x × 1|
Since the absolute value of x is independent of n, we can drop it from the limit.
Therefore, for the series f(x) to converge, |x × 1| < 1.
This implies -1 < x < 1.
Hence, the interval of convergence for f(x) is (-1, 1).
Now let's find the intervals of convergence for f'(x), the derivative of f(x).
Differentiating f(x) term by term, we get:
f'(x) = 1 + x/2 + x²/3²+ x³/4² + ...
We can apply the ratio test to find the intervals of convergence for f'(x):
|r| = |(x⁽ⁿ⁺¹⁾ / (n+1)²) / (xⁿ / n²)|
= |(x⁽ⁿ⁺¹⁾ × n²) / ((n+1)² × xⁿ)|
= |x × (n² / (n+1)²)|
Taking the limit as n approaches infinity:
lim |x × (n² / (n+1)²)|
= |x × 1|
Since the absolute value of x is independent of n, we can drop it from the limit.
Therefore, for the series f'(x) to converge, |x × 1| < 1.
This implies -1 < x < 1.
Hence, the intervals of convergence for f'(x) are (-1, 1).
Finally, let's find the intervals of convergence for f''(x), the second derivative of f(x).
Differentiating f'(x) term by term, we get:
f''(x) = 0 + 1/2 + x/3² + x²/4²+ ...
Again, we can apply the ratio test to find the intervals of convergence for f''(x):
|r| = |(x⁽ⁿ⁺¹⁾ / (n+1)²) / (xⁿ / n²)|
= |(x⁽ⁿ⁺¹⁾ × n²) / ((n+1)² × xⁿ)|
= |x ×(n² / (n+1)²)|
Taking the limit as n approaches infinity:
lim |x × (n² / (n+1)²)|
= |x × 1|
Since the absolute value of x is independent of n, we can drop it from the limit.
Therefore, for the series f''(x) to converge, |x × 1| < 1.
This implies -1 < x < 1.
Hence, the intervals of convergence for f''(x) are (-1, 1).

You have $1000 invested for 3 years and get 10% interest.
Answer:
$1331 compounded annually after three years
Step-by-step explanation:
Given the following question:
1000 dollars invested (princpal)....
You invest that 1000 dollars for three years (time)....
Assuming it's compounded annually we need to substitute the values into the formula to calculate compound interest.
\(A=P(1+\frac{r}{n} )^{nt}\)
\(P=1000\)
\(\frac{r}{n} =\frac{10}{100} =10\div100=0.1\)
\(nt=(1)(3)\)
\(A=1000(1+0.1)^{(1)(3)}\)
\(1\times3=3\)
\(A=1000(1+0.1)^{3}\)
\(1+0.1=1.1\)
\(1.1^3=1.1\times1.1\times1.1=1.331\)
\(A=1000\times1.331\)
\(1000\times1.331=1331\)
\(=1331\)
Which means after a intital investment of 1000 dollars you will have "1331 dollars" after three years compounded annually.

new cell phone plan costs $39.99 per month plus $0.18 for each text message you send or receive you have at most $44 to spend on your cell phone bill what is the maximum number of text messages that you can send or receive next month
Answer:
22
Explanation:
The cell phone plan costs $39.99 per month plus $0.18 for each text message.
Let the number of text messages sent or receive = t
The cost, C in a month will be:
\(C=39.99+0.18t\)If you have at most $44 to spend, it means the cost can be less than or equal to $44.
\(39.99+0.18t\leq44\)We then solve the inequality for t.
\(\begin{gathered} \text{Subtract 39.99 from both sides} \\ 39.99-39.99+0.18t\leq44-39.99 \\ 0.18t\leq4.01 \\ \text{Divide both sides by 0.18} \\ \frac{0.18t}{0.08}\leq\frac{4.01}{0.18} \\ t\leq22.3 \end{gathered}\)Since text messages cannot be decimal, the maximum number of text messages that you can send or receive next month is 22.
