The value of c in the triangle is 14.
How to angles of triangle?A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.
In the triangle LMN, m ∠L = (3c + 66)°. The exterior angle to ∠L measures 72 degrees.
Therefore, let's find c.
Hence, the sum of the exterior angle and the interior angle is 180 degrees.
Therefore,
72 + 3c + 66 = 180
3c = 180 - 66 - 72
3c = 42
divide both sides by 3
c = 42 / 3
Therefore,
c = 14

The t critical value and confidence interval must be determined.
What is confidence interval?A confidence interval (CI) is a range of estimates for an unknown parameter in frequentist statistics.
The 95% confidence level is the most popular, however other levels, such 90% or 99%, are occasionally used when computing confidence intervals.
The percentage of related CIs over the long run that include the parameter's actual value is represented by the confidence level.
For instance, 95% of all intervals calculated at the 95% confidence level should include the parameter's actual value.
The sample size, sample variability, and confidence level are all variables that have an impact on the width of the CI.
Assuming all other factors remain constant, a larger sample results in a narrower confidence interval, while a sample with more variability results in a wider confidence interval.
According to our question-
At a confidence level of 90%, we have α = 1 - 0.90 = 0.1
α/2 = 0.1/2 = 0.05.
Degree of freedom = 4-1 = 3

whenever suzan sees a bag of marbles, she grabs a handful at random. she has seen a bag containing four red marbles, five green ones, three white ones, and two purple ones. she grabs eight of them. find the probability of the following event, expressing it as a fraction in lowest terms. she has at least one green one.
For this problem, it is best to consider E to be the case in which she has all of the green ones, and then apply the formula for calculating the probability of a complement.
. To determine the likelihood that she will receive all of the green ones, we must first determine two values: the total number of possible outcomes, n(S), and the total number of favorable outcomes for the given event. Because she selects 8 marbles from a total of 11, n(S) = C(11, 8) = 165. To get all the green ones, she must first select three red marbles from a set of three, and then select the remaining five marbles.
from the 8 non-red ones. There are (3,3)(8, 5) = 56 ways to do this. Thus,
() =56/165
. The probability of not occurring is then (′) = 1 −56/165=109/165
, so this is the probability that she does get all the green one.

The rate at which the energy pass through an area of 1.0 m² at 2.0 km is equal to 1.97 × 10⁹ J/s.
How to calculate the intensity of the earthquake from the source?At a constant power, the intensity of a wave is inversely proportional to the distance from the source. Mathematically, the intensity of a wave with respect to the distance from a source can be modeled (represented) by this mathematical expression;
I ∝ 1/r²
Where:
I represents the intensity of a wave.r represents the distance from a source.Next, we would re-write the mathematical expression and then determine the intensity of a wave from source as follows;
I₁/I₂ = r₂²/r₁²
I₁ = I₂(r₂²/r₁²)
Note: We know that its intensity when it passed a point from the source is 2.0 km.
Substituting the given parameters into the formula, we have;
I₁ = 2.8 × 10⁶ × (53²/2²)
I₁ = 1.97 × 10⁹ J/m²s.
Now, we can calculate the rate of the energy by using this formula;

dB/dt = 2×10^{-6} + 1×10^{-6}/2 - 5×10^{-6}
dB/dt = - 2×10^{-6}
Now finding the area
Area = 1/2 wh
Firstly converting the w and h in m
So w = 0.20 m, h = 0.30 m
Area = 1/2 *0.20*0.30
Area = 0.03 square m
The induced EMF is
EMF = -AdB/dt
EMF = -(0.03)*(- 2×10^{-6})
EMF = 0.06×10^{-6}
The magnitude of the current induced in the wire is
I = EMF/R
I = 0.06×10^{-6}/5
I = 0.012×10^{-6}
I = 1.2×10^{-8}
Now, the direction of the current induced in the wire is counter clockwise.

You want to be able to withdraw $30,000 each year for 25 years. Your account earns 8% interest.
a. How much do you need in your account at the beginning
Answer: you need to have at least $312,500 in your account at the beginning.
Step-by-step explanation:
The total amount of money you will need to withdraw over the 25-year period is $30,000 * 25 years = $750,000. To find the total amount of interest you will earn, we need to use a compound interest formula. The formula for compound interest is:
A = P(1 + r/n)^nt
where A is the total amount of money you will have in your account after 25 years, P is the initial amount of money in your account, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In our case, we have A = $750,000, P = ?, r = 8%, n = 1 (since the interest is compounded annually), and t = 25. Plugging these values into the formula, we get:
$750,000 = P * (1 + 0.08/1)^1 * 25
We can simplify this equation to:
$750,000 = P * 1.08^25
To find the value of P, we can divide both sides of the equation by 1.08^25:
$750,000 / 1.08^25 = P
We can use a calculator to compute the value of 1.08^25, which is approximately 2.4. This means that the initial amount of money you need in your account is $750,000 / 2.4 = $312,500.
Therefore, to be able to withdraw $30,000 each year for 25 years and earn 8% interest on your account, you need to have at least $312,500 in your account at the beginning.
