10% of people are left handed. If 800 people are randomly selected, find the likelihood that at least 12% of the sample is left handed
The likelihood of at least 12% of the sample being left-handed is approximately 0.007 or 0.7%.
Let X be the number of left-handed people in a sample of 800 individuals. Since the probability of a person being left-handed is 0.1, the probability of a person being right-handed is 0.9. Then, X follows a binomial distribution with n = 800 and p = 0.1.
P(X ≥ 0.12*800) = P(X ≥ 96)
where 96 is the smallest integer greater than or equal to 0.12*800.

Brody is going to invest $350 and leave it in an account for 18 years. Assuming the interest is compounded daily, what interest rate, to the
neatest tenth of a percent, would be required in order for Brody to end up with $790?
If the interest is compounded daily, the interest rate is 4.5%.
How to find the interest rate?To determine the interest rate, we can use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:
A = the final amount, $790
P = the principal, $350
r = the interest rate
n = the number of times the interest is compounded per year, in this case daily (n = 365)
t = the time period in years, 18
Substituting the values :
790 = 350(1 + r/365)³⁶⁵ˣ¹⁸
790 = 350(1 + r/365)⁶⁵⁷⁰
790/350 = (1 + r/365)⁶⁵⁷⁰
ln(790/350) = 6570 * ln (1 + r/365)
Using the property of logarithms that ln(1 + x) ~ x for small values of x, we can approximate the right-hand side as:
[ln(790/350)]/6570 = r/365
r = 0.045

a) Calculate the circumference of each pancake.
b) Calculate the area of each pancake.
Answer:
a) 18.84 cm
b) 28.26 cm²
Step-by-step explanation:
We Know
Each pancake is a circle with a diameter of 6 centimeters.
a) Calculate the circumference of each pancake.
Circumference of circle = d · π
d = 6 cm
We Take
6 · 3.14 = 18.84 cm
So, the circumference of each pancake is 18.84 cm.
b) Calculate the area of each pancake.
Area of circle = r² · π
r = 1/2 · d
r = 1/2 · 6 = 3 cm
We Take

Find the equation of the tangent line at (6, f(6)). y =
The equation of the tangent line at (6, f(6)) is y = 6x - 48.
a. The slope of the secant line joining (2, f(2)) and (7, f(7)) is:
slope = (f(7) - f(2)) / (7 - 2)
We can find f(7) and f(2) by plugging in x = 7 and x = 2 into the expression for f(x):
f(7) = 7² - 6(7) = 7
f(2) = 2² - 6(2) = -8
Substituting these values into the slope formula, we get:
slope = (7 - (-8)) / (7 - 2) = 3
Therefore, the slope of the secant line joining (2, f(2)) and (7, f(7)) is 3.
b. The slope of the secant line joining (6, f(6)) and (6 + h, f(6 + h)) is:
slope = (f(6 + h) - f(6)) / ((6 + h) - 6) = (f(6 + h) - f(6)) / h
We can find f(6) and f(6 + h) by plugging in x = 6 and x = 6 + h into the expression for f(x):
f(6) = 6² - 6(6) = -12
f(6 + h) = (6 + h)² - 6(6 + h) = h² - 6h + 36 - 36 - 6h = h² - 12h
Substituting these values into the slope formula, we get:
slope = (h² - 12h - (-12)) / h = h - 12
Therefore, the slope of the secant line joining (6, f(6)) and (6 + h, f(6 + h)) is h - 12.
c. The slope of the tangent line at (6, f(6)) is the derivative of f(x) at x = 6:
f'(x) = 2x - 6
f'(6) = 2(6) - 6 = 6
Therefore, the slope of the tangent line at (6, f(6)) is 6.
d. To find the equation of the tangent line at (6, f(6)), we use the point-slope form of a line:
y - f(6) = f'(6)(x - 6)
Substituting f(6) and f'(6) into this equation, we get:
y - (-12) = 6(x - 6)
Simplifying, we get:
y = 6x - 48
Therefore, the equation of the tangent line at (6, f(6)) is y = 6x - 48.

B between 1 and 1 1/2
C between 1 1/2 and 2
D between 2 and 2 1/2
Elise chose D as the correct answer. How did she get that answer?
Step-by-step explanation:
To estimate the difference between 5 1/2 and 3 5/9, we can first round the fractions to the nearest whole number or simpler fractions. In this case, we can round 1/2 to 1/2 and 5/9 to 1/2 as well. Now, we have:
5 1/2 − 3 1/2
Subtracting the whole numbers, we get:
5−3=2

1/2 − 1/2 = 0
So, the estimated difference is 2, which falls between 2 and 2 1/2. Therefore, Elise chose option D as the correct answer.
Use the rules to find derivatives of the following functions at the specified values
h(x) = 8x at x = 4
h'(4) = _____
To find the derivative of h(x) = 8x, we use the power rule, which states that the derivative of x^n is nx^(n-1). Applying this rule to h(x), we get h'(x) = 8.
To find the value of h'(4), we simply plug in x = 4 into our derivative expression: h'(4) = 8.
Therefore, the derivative of h(x) = 8x at x = 4 is h'(4) = 8.
To find the derivative of the function h(x) = 8x at x = 4, you can use the power rule for differentiation. The power rule states that if h(x) = x^n, then h'(x) = n * x^(n-1).
For h(x) = 8x, n = 1, so:
h'(x) = 1 * 8x^(1-1) = 8
Now, to find h'(4), just plug in x = 4:
h'(4) = 8
So, h'(4) = 8.

In triangle abc, point d is on side ac, ab=bd=dc=12 inches, and measurement of angle bdc= 2 times the measurement of angle abd. find ac
The length of AC in triangle ABC is 24 inches.
In triangle ABC, let point D be on side AC such that AB = BD = DC = 12 inches. We are given that the measure of angle BDC is twice the measure of angle ABD.
To find the length of AC, we can use the Law of Cosines. This law relates the lengths of the sides of a triangle to the cosine of one of its angles. In this case, we can apply the Law of Cosines to triangle ABD to find the length of AD:
AD^2 = AB^2 + BD^2 - 2 * AB * BD * cos(ABD)
Since AB = BD = 12 inches, we have:
AD^2 = 12^2 + 12^2 - 2 * 12 * 12 * cos(ABD)
AD^2 = 288 - 288 * cos(ABD)
Now, let's consider triangle BDC. We are given that the measure of angle BDC is twice the measure of angle ABD. Let's denote the measure of angle ABD as x. Therefore, the measure of angle BDC is 2x.
Since the sum of angles in a triangle is 180 degrees, we can write:
x + 2x + angle BCD = 180
3x + angle BCD = 180
angle BCD = 180 - 3x
Now, let's apply the Law of Cosines to triangle BDC to find the length of BC:
BC^2 = BD^2 + CD^2 - 2 * BD * CD * cos(BDC)
BC^2 = 12^2 + 12^2 - 2 * 12 * 12 * cos(2x)
BC^2 = 288 - 288 * cos(2x)
Since AD = DC, we have AD = 12 inches. Now we can write the equation for the total length AC:
AC = AD + DC
AC = 12 + 12
AC = 24 inches
Therefore, the length of AC in triangle ABC is 24 inches.

3) The expression In(4x^5) - In(x^3) - In 4 can be simplified using the properties of logarithms. We know that ln(a) - ln(b) = ln(a/b) and ln(a^n) = n ln(a), so we can write:In(4x^5) - In(x^3) - In 4 = In[(4x^5)/(x^3)] - In 4= In(4x^2) - In 4= In(4x^2/4)= In(x^2)Thus, the simplified expression is In(x^2).4) To solve this problem, we need to use the formula for compound interest:A = P(1 + r/n)^(nt)where A is the final amount, P is the initial amount, r is the interest rate (as a decimal), n is the number of times interest is compounded per year, and t is the number of years.We want to find t when A = 3P and r = 0.02 (since the price of beef has inflated by 2%). We are told that interest is compounded biannually, so n = 2. Plugging in these values and solving for t, we get:3P = P(1 + 0.02/2)^(2t)3 = (1.01)^2tln(3) = ln(1.01^2t)ln(3) = 2t ln(1.01)t = ln(3) / (2 ln(1.01))Using a calculator, we find t ≈ 34.64 years.

- In(a) - In(b) = In(a/b)
- In(a^b) = b * In(a)
So, we can rewrite the expression as:
In(4x^5 / (x^3 * 4))
Now, we can simplify the expression inside the natural logarithm:

where A is the final amount, P is the initial amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years. In this case, we want the final amount to be triple the initial amount:

To solve for t, we can divide both sides by P:
3 = (1 + 0.01)^(2t)
Now, take the natural logarithm of both sides and use the properties of logarithms:
ln(3) = ln((1 + 0.01)^(2t))
ln(3) = 2t * ln(1 + 0.01)
Finally, isolate t:
t = ln(3) / (2 * ln(1 + 0.01))
t ≈ 109.96

Monica deposits $ 300 into a savings account that pays a simple interest rate of 3.4%. Paul deposits $400 into a savings account that pays a simple interest rate of 3.3 %. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she correct? Justify your response.
Monica's claim is incorrect. Even though her interest rate is higher, she will earn less interest, $10.20, after one year than Paul because her initial deposit is lower.
Paul will earn more interest of $13.20 because he deposited more money, even though his interest rate is slightly lower.
To determine who will earn more interest in one year, we shall calculate the interest earned by each person using the simple interest formula.
What is the simple interest formula?The formula for simple interest is:
I = P * r * t
where:
I = the interest earned
P = the principal (the amount deposited)
r = the interest rate (as a decimal)
t =s the time (in years)
For Monica, we are given:
P = $300
r = 0.034 (the interest rate is 3.4%)
t = 1 (the interest earned in one year)
Plugging these values, we have:
I = 300 * 0.034 * 1 = $10.20
So, Monica will earn $10.20 in interest after one year.
For Paul, we are given:
P = $400
r = 0.033 (interest rate = 3.3%)
t = 1 (interest earned in one year)
Plugging the values, we get:
I = 400 * 0.033 * 1 = $13.20
So, Paul will earn $13.20 in interest after one year.
Therefore, Monica's claim is incorrect. Monica will earn $10.20 in interest after one year while Paul will earn $13.20 in interest after one year.

y varies inversely as x. y= 27 when x=5 Find y when x=3
As y varies inversely as x, the value of y when x = 3 is 45.
What is the value of y when x = 3?Inverse proportionality is expressed as:
y ∝ 1/x
Hence:
y = k/x
Where k is the constant of proportionality.
First, we determine the constant of proportionality.
Using the information given in the problem.
When x = 5, y = 27
Substituting these values into the formula, we get:
y = k/x
27 = k/5
k = 135
Now that we have found the value of k, we can use the formula to find y when x = 3. Substituting x = 3 and k = 135, we get:
y = k/x
y = 135/3
y = 45
Therefore, the value of y is 45.

Watch Talk to a Tutor Read it MY NOTE Cost, revenue, and profit are in dollars and x is the number of units. A firm knows that its marginal cost for a product is MC - 4x + 25, that its marginal revenue is MR - 55 - 6x, and that the cost of production of 80 units is $14,920.

The profit is positive, the firm makes a profit of $21,243 at the optimal level of production.
Cost of producing 40 units
We know that the total cost of producing 30 units is $6000. Let's denote the total cost function by C(x), where x is the number of units produced. Then, we have:
C(30) = $6000
The marginal cost function is given as MC = 8x + 70. Integrating this function, we get the total cost function as:
C(x) = [tex]4x^2[/tex] + 70x + C
To find the value of the constant C, we use the fact that C(30) = $6000:
4[tex](30)^2[/tex] + 70(30) + C = $6000
Solving for C, we get:
C = $300
Therefore, the total cost function is:
C(x) = [tex]4x^2[/tex] + 70x + $300
To find the cost of producing 40 units, we evaluate C(40):
C(40) = [tex]4(40)^2[/tex] + 70(40) + $300
C(40) = $7000
Therefore, the cost of producing 40 units is $7000.
Optimal level of production:
The optimal level of production is the value of x that maximizes the profit function. To find this value, we need to set the marginal cost equal to the marginal revenue:
MC = MR
8x + 70 = -6x + 55
Solving for x, we get:
x = 5/7
Since the optimal level of production should be a whole number, we round x up to 1 unit.
Therefore, the optimal level of production is 1 unit.
Profit function:
The profit function is given as:
P(x) = R(x) - C(x)
where R(x) is the revenue function and C(x) is the cost function.
The marginal revenue function is given as MR = -6x + 55. Integrating this function, we get the revenue function as:
R(x) = -[tex]3x^2[/tex] + 55x + D
To find the value of the constant D, we use the fact that the revenue at x = 80 is $14,920:
[tex]-3(80)^2[/tex] + 55(80) + D = $14,920
Solving for D, we get:
D = $21,520
Therefore, the revenue function is:
R(x) = -[tex]3x^2[/tex] + 55x + $21,520
Substituting the cost function and revenue function in the profit function, we get:
P(x) = ([tex]-3x^2[/tex] + 55x + $21,520) - (4x^2 + 25x + $300)
Simplifying, we get:
P(x) = -[tex]7x^2[/tex] + 30x + $21,220
Therefore, the profit function is P(x) = [tex]-7x^2[/tex] + 30x + $21,220.
Profit or loss at the optimal level:
To find the profit or loss at the optimal level, we evaluate the profit function at x = 1:
P(1) = [tex]-7(1)^2[/tex] + 30(1) + $21,220
P(1) = $21,243
Since the profit is positive, the firm makes a profit of $21,243 at the optimal level of production.
