14). Find the measures of both angles.
xo
(3x +20)°
Answer:
40 degrees and 140 degrees
Step-by-step explanation:
To solve this problem you can add x+3x+20 and set that equal to 180. (We can do this because angle x and angle 3x + 20 make a linear pair. Knowing this we can estimate that both angles added together will equal 180)
Let us add x + 3x + 20 = 180 to find x. We can then substitute that into the equation.
[tex]x+3x+20=180 :a\\\\4x+20=180 :b\\\\4x + 20 -20=180-20:c\\\\4x=160:d\\\\\frac{4x}{4} = \frac{160}{4}:e\\\\x=40:f[/tex]
a: So in this part, we have rewritten the equation to make it easier to solve
b: In this step, you combine the like terms x+3x to get 4x
c: In step c, you are subtracting 20 from both sides to keep constants on one side and variables on the right
d: In this last step the equation has been simplified to make it easier to solve.
e: To isolate x you have to divide both sides by 4, we do this because the coefficient of x is 4 so you divide the equation by 4 to cancel it out.
f: You rewrite and simplify the equation.
Now to find the measure of both angles you substitute x into the equation.
The first angle's value is 40 degrees and the second is 140 degrees.

I have two similar triangles and can't find x. since I'm too lazy to download the app, the larger one has two sides of 6 and 12 and the smaller has two sides of x-3 and x+1. what is x??
Answer:
7
Step-by-step explanation:
We can use the fact that the corresponding sides of similar triangles are in proportion to each other.
Let's compare the corresponding sides of the two triangles:
Corresponding sides and ratio
larger triangle's side of length 6 larger triangle's side of length 12Ratio
smaller triangle's side of length x-3smaller triangle's side of length x+1Since the triangles are similar, we know that these ratios are equal. That is,
6 / (x-3) = 12 / (x+1)
We can simplify this equation by cross-multiplying:
6(x+1) = 12(x-3)
Expanding and simplifying:
6x + 6 = 12x - 36
42 = 6x
x = 7
Therefore, x has a value of 7.

Out of 300 applicants for a job, 134 are male and 40 are male and have a graduate degree. You were asked to find the probability that a randomly chosen applicant has a graduate degree, given that they are male.
Answer: We can use Bayes' theorem to find the probability that a randomly chosen applicant has a graduate degree, given that they are male. Bayes' theorem states:
P(A|B) = P(B|A) * P(A) / P(B)
where A and B are events, P(A|B) is the conditional probability of event A given that event B has occurred, P(B|A) is the conditional probability of event B given that event A has occurred, P(A) is the prior probability of event A, and P(B) is the prior probability of event B.
In this case, we want to find P(grad degree | male), which is the probability that an applicant has a graduate degree given that they are male. Using Bayes' theorem, we have:
P(grad degree | male) = P(male | grad degree) * P(grad degree) / P(male)
We are given that 134 applicants are male, and 40 of those males have a graduate degree. Therefore:
P(male | grad degree) = 40 / total number of applicants with a graduate degree
We are not given the total number of applicants with a graduate degree, but we can find it using the fact that 40 applicants are male and have a graduate degree, and that there are 134 male applicants in total. Therefore:
total number of applicants with a graduate degree = 40 / (40/134) = 118.33 (rounded to the nearest whole number)
Next, we need to find the prior probability of having a graduate degree, P(grad degree). We can use the total number of applicants and the number of applicants with a graduate degree to calculate this probability:
P(grad degree) = number of applicants with a graduate degree / total number of applicants = 118 / 300 = 0.3933 (rounded to four decimal places)
Finally, we need to find the prior probability of being male, P(male). This probability can be calculated similarly:
P(male) = number of male applicants / total number of applicants = 134 / 300 = 0.4467 (rounded to four decimal places)
Now, we can substitute these values into Bayes' theorem to find the probability that a randomly chosen applicant has a graduate degree, given that they are male:
P(grad degree | male) = (40 / 118) * 0.3933 / 0.4467 = 0.332 (rounded to three decimal places)
Therefore, the probability that a randomly chosen applicant has a graduate degree, given that they are male, is approximately 0.332 or 33.2%.

If g(x) = 3x -2 and (gof)(x) = 15x + 10, find f(x).
Answer:
the function f(x) is f(x) = 5x + 4.
Step-by-step explanation:
To find f(x), we need to use the formula:
(gof)(x) = g(f(x)) = 3f(x) - 2
We are given that (gof)(x) = 15x + 10, so we can substitute this expression into the formula to get:
3f(x) - 2 = 15x + 10
Simplifying this equation, we get:
3f(x) = 15x + 12
Dividing both sides by 3, we get:
f(x) = 5x + 4
Therefore, the function f(x) is f(x) = 5x + 4.
22 randomly picked people were asked if they rented or owned their own home, 9 said they rented. Obtain a point estimate of the proportion of home owners. Use a 95% level of confidence.
point
Answer:
True proportion of homeowners in the population lies between 0.333 and 0.847
Step-by-step explanation:
If 9 out of 22 randomly picked people said they rented their homes, then the remaining 13 must own their homes. Therefore, the point estimate of the proportion of homeowners is:
Point estimate = Number of homeowners / Total number of people surveyed
Point estimate = 13 / 22
Point estimate = 0.59 (rounded to two decimal places)
To calculate the 95% confidence interval for the true proportion of homeowners, we can use the following formula:
Confidence interval = Point estimate ± (Z-value x Standard error)
where the Z-value corresponds to the desired level of confidence and the standard error is given by:
Standard error = sqrt [ (Point estimate x (1 - Point estimate)) / Sample size]
For a 95% confidence interval, the Z-value is 1.96 (from the standard normal distribution). Using the point estimate obtained earlier, the sample size is 22, and we can calculate the standard error as:
Standard error = sqrt [ (0.59 x 0.41) / 22 ]
Standard error = 0.131 (rounded to three decimal places)
Substituting these values into the formula, we get:
Confidence interval = 0.59 ± (1.96 x 0.131)
Confidence interval = 0.59 ± 0.257
Confidence interval = (0.333, 0.847)
Therefore, with 95% confidence, we can say that the true proportion of homeowners in the population lies between 0.333 and 0.847.

Find the volume of the composite solid. Round your answer to the nearest hundredth.
Therefore, the volume of the composite solid is approximately 1357.28 cubic feet, rounded to the nearest hundredth.
What is volume?Volume is a measure of the amount of space occupied by an object or a substance. In other words, it is the three-dimensional space that an object or substance occupies. The SI unit for volume is cubic meters (m³), although other units such as cubic centimeters (cm³) and liters (L) are also commonly used.
Here,
The composite solid is made up of a hemisphere and a cone with the same base radius and height. The volume of the hemisphere is given by (2/3)πr³, and the volume of the cone is given by (1/3)πr²h, where r is the radius and h is the height. Given that the radius is 6 feet and the height is 12 feet, we can find the volumes of the hemisphere and the cone as follows:
Volume of hemisphere = (2/3)π(6³)
= 288π cubic feet
Volume of cone = (1/3)π(6²)(12)
= 144π cubic feet
The total volume of the composite solid is the sum of the volumes of the hemisphere and the cone, which is:
Total volume = Volume of hemisphere + Volume of cone
= 288π + 144π
= 432π
To find the numerical value of this volume, we can use the approximation π ≈ 3.14 and round the result to the nearest hundredth:
Total volume ≈ 432(3.14)
= 1357.28 cubic feet

An angle measures 125°. Through what fraction of a circle does the angle turn?
If an angle measure 125° then the angle measures a fraction of 25/72 of a full circle.
What is a circle?A circle is a two-dimensional geometric shape that is defined as the set of all points that are equidistant from a single point, called the center. The distance from the center to any point on the circle is called the radius, and the distance across the circle, passing through the center, is called the diameter. The circumference of a circle is the distance around the edge or perimeter of the circle. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle, and π (pi) is a mathematical constant that represents the ratio of the circumference to the diameter of a circle, approximately equal to 3.14159.
According to the given informationA circle has 360 degrees. To find what fraction of a circle an angle measures, we can divide the angle by 360. In this case, the angle measures 125 degrees, so the fraction of a circle it turns can be calculated as:
125/360 = 0.347222222...
To simplify this fraction, we can multiply both the numerator and denominator by 2:
125/360 = (1252)/(3602) = 250/720
We can further simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 10:
250/720 = (2510)/(7210) = 25/72
Therefore, the angle measures a fraction of 25/72 of a full circle.

how do i use change of base formula with logorothims
To use the change of base formula, we first identify the base of the original logarithm and the desired base of the new logarithm.
The change of base formula is a useful tool in logarithmic functions that allows us to rewrite a logarithm with one base as an equivalent logarithm with a different base. The formula is as follows:
logᵦ a = logᵦ(x) / logₐ(x)
where a is the value being logged, β is the base of the original logarithm, and x is any positive number other than 1.
We then apply the formula by taking the logarithm of the value being logged with the desired base, and dividing it by the logarithm of the same value with the original base.
For example, let's say we want to rewrite the logarithm log₂ 8 in base 10. Using the change of base formula, we have:
log₂ 8 = log₁₀ 8 / log₁₀ 2
The value of log₁₀ 8 is simply 0.9031, and the value of log₁₀ 2 is 0.3010, so we have:
log₂ 8 = 0.9031 / 0.3010 ≈ 3
Therefore, log₂ 8 is equivalent to log₁₀ 8 ≈ 3. By using the change of base formula, we can simplify logarithmic expressions and evaluate them using common logarithms or natural logarithms.

How to calculate the valueUse the amount in 11/1 as your balance, then compute by deducting the checks (chk) and debit purchases and adding the deposits. Then get the difference.
Check Register:
Total = 397.45 - 50.32 - 16.32 + 190.67
Total = 521.48
Online Statement:
Total = 486.44 - 84.80 - 19.73 - 16.32 + 190.67
Total = 556.26
Difference = online - check register
Difference = 34.78
On 11/10 and 11/18, check and online have the same transactions (same date, same amount) which are 16.32 and 190.67. Add them together to get 206.99

Christian earned a grade of 67% on his multiple choice science final that had a total of 200 problems. How many problems on the final exam did Christian answer correctly?
Answer: 134.
Step-by-step explanation:
First revert 67% into it's decimal form. You get 0.67. Then, multiply 0.67 by 200 because there were 200 problems.
0.67 x 200
67 x 2
134
So, christian got 134 out of 200 problems correct.

the function g(x) = 12x^2-sinx is the first derivative of f(x). If f(0)=-2 what is the value of f(2pi
Answer:
[tex]f(2\pi) = 32\pi^3 - 2[/tex]
Step-by-step explanation:
Main steps:
Step 1: Use integration to find a general equation for f
Step 2: Find the value of the constant of integration
Step 3: Find the value of f for the given input
Step 1: Use integration to find a general equation for f
If [tex]f'(x) = g(x)[/tex], then [tex]f(x) = \int g(x) ~dx[/tex]
[tex]f(x) = \int [12x^2 - sin(x)] ~dx[/tex]
Integration of a difference is the difference of the integrals
[tex]f(x) = \int 12x^2 ~dx - \int sin(x) ~dx[/tex]
Scalar rule
[tex]f(x) = 12\int x^2 ~dx - \int sin(x) ~dx[/tex]
Apply the Power rule & integral relationship between sine and cosine:
Power Rule: [tex]\int x^n ~dx=\frac{1}{n+1}x^{n+1} +C[/tex]sine-cosine integral relationship: [tex]\int sin(x) ~dx=-cos(x)+C[/tex][tex]f(x) = 12*(\frac{1}{3}x^3+C_1) - (-cos(x) + C_2)[/tex]
Simplifying
[tex]f(x) = 12*\frac{1}{3}x^3+12*C_1 +cos(x) + -C_2[/tex]
[tex]f(x) = 4x^3+cos(x) +(12C_1 -C_2)[/tex]
Ultimately, all of the constant of integration terms at the end can combine into one single unknown constant of integration:
[tex]f(x) = 4x^3 + cos(x) + C[/tex]
Step 2: Find the value of the constant of integration
Now, according to the problem, [tex]f(0) = -2[/tex], so we can substitute those x,y values into the equation and solve for the value of the constant of integration:
[tex]-2 = 4(0)^3 + cos(0) + C[/tex]
[tex]-2 = 0 + 1 + C[/tex]
[tex]-2 = 1 + C[/tex]
[tex]-3 = C[/tex]
Knowing the constant of integration, we now know the full equation for the function f:
[tex]f(x) = 4x^3 + cos(x) -3[/tex]
Step 3: Find the value of f for the given input
So, to find [tex]f(2\pi)[/tex], use 2 pi as the input, and simplify:
[tex]f(2\pi) = 4(2\pi)^3 + cos(2\pi) -3[/tex]
[tex]f(2\pi) = 4*8\pi^3 + 1 -3[/tex]
[tex]f(2\pi) = 32\pi^3 - 2[/tex]
Answer:
[tex]f(2 \pi)=32\pi^3-2[/tex]
Step-by-step explanation:
Fundamental Theorem of Calculus[tex]\displaystyle \int \text{f}(x)\:\text{d}x=\text{F}(x)+\text{C} \iff \text{f}(x)=\dfrac{\text{d}}{\text{d}x}(\text{F}(x))[/tex]
If differentiating takes you from one function to another, then integrating the second function will take you back to the first with a constant of integration.
Given:
[tex]g(x)=12x^2-\sin x[/tex][tex]f(0)=-2[/tex]If g(x) is the first derivative of f(x), we can find f(x) by integrating g(x) and using f(0) = -2 to find the constant of integration.
[tex]\boxed{\begin{minipage}{4 cm}\underline{Integrating $x^n$}\\\\$\displaystyle \int x^n\:\text{d}x=\dfrac{x^{n+1}}{n+1}+\text{C}$\end{minipage}}[/tex] [tex]\boxed{\begin{minipage}{4 cm}\underline{Integrating $\sin x$}\\\\$\displaystyle \int \sin x\:\text{d}x=-\cos x+\text{C}$\end{minipage}}[/tex]
[tex]\begin{aligned} \displaystyle f(x)&=\int f'(x)\; \text{d}x\\\\&=\int g(x)\;\text{d}x\\\\&=\int (12x^2-\sin x)\;\text{d}x\\\\&=\int 12x^2\; \text{d}x-\int \sin x \; \text{d}x\\\\&=12\int x^2\; \text{d}x-\int \sin x \; \text{d}x\\\\&=12\cdot \dfrac{x^{(2+1)}}{2+1}-(-\cos x)+\text{C}\\\\&=4x^{3}+\cos x+\text{C}\end{aligned}[/tex]
To find the constant of integration, substitute f(0) = -2 and solve for C:
[tex]\begin{aligned}f(0)=4(0)^3+\cos (0) + \text{C}&=-2\\0+1+\text{C}&=-2\\\text{C}&=-3\end{aligned}[/tex]
Therefore, the equation of function f(x) is:
[tex]\boxed{f(x)=4x^3+ \cos x - 3}[/tex]
To find the value of f(2π), substitute x = 2π into function f(x):
[tex]\begin{aligned}f(2 \pi)&=4(2 \pi)^3+ \cos (2 \pi) - 3\\&=4\cdot 2^3 \cdot \pi^3+1 - 3\\&=32\pi^3-2\\\end{aligned}[/tex]
Therefore, the value of f(2π) is 32π³ - 2.
