Answers
From the given triangle, x has a value of 35°.
As a result, one of the triangle's sides has been stretched to create an exterior angle of 125° outside angle.
Which angles are adjacent?Angles that are always located near one another, sharing a similar vertex and common side but not overlapping, are said to be adjacent angles.
According to the above figure, the tringle's exterior angle is 125°, and y is an adjacent angle to that.
Now, 125°+ y =180°
y = 180°-125°
y = 55°
As a result, the supplied triangle's value for y is 55°.
The sum of the triangle law,
55°+ 90° + x = 180°
x = 35°
Therefore the value of x = 35°

The measure of angle JKM is 26°
What is exterior angle theorem?The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the opposite angles in the triangle.
Also the sum of angle in a triangle is 180°
Therefore ;
3x+64 = 5x+4
collecting like terms
5x -3x = 64-4
2x = 60
x = 60/2
x = 30
since x = 30
value of the exterior angle = 5x+4
= 5×30+4
= 150+4 = 154
therefore angle JKM = 180-( 154)

The company performed another experiment in which they tested three website designs to see which one would lead to the highest probability of a purchase. The first (design A) used enhanced product information, the second (design B) used extensive iconography, and the third (design C) allowed the customer to submit their own product ratings. After 6 weeks of testing, the designs delivered probabilities of purchase of 4.5%, 5.2%, and 3.8% respectively. Equal numbers of customers were sent randomly to each website design. what is the probability that a customer who visited made a purchase?
Answers
The probability that a customer who visited any of the three website designs made a purchase is 4.5%.
To find the probability that a customer who visited any of the three website designs made a purchase, we need to find the average probability of purchase across all three designs.
We can do this by taking the mean of the three probabilities:
Mean probability = (4.5% + 5.2% + 3.8%) / 3
= 13.5% / 3
= 4.5%
This assumes that the customers were randomly assigned to each design and that there were no other factors that may have influenced their purchasing behavior. Additionally, the sample size and duration of the experiment may also affect the accuracy of the results.

The ordered pairs model an exponential function, where w is the function name and t is the input variable.

What is the function equation in sequence notation?
ANSWER: 60(4)t−1
just took the test
Answers
Answer: w(t) = 60 * 4^(t-1).
Step-by-step explanation:
The given ordered pairs model an exponential function of the form w(t) = ab^t, where w is the function name, t is the input variable, a is the initial value, and b is the growth factor.
From the first ordered pair (1, 60), we can see that the initial value a is 60. From the second and third ordered pairs (2, 240) and (3, 960), we can see that the output value is multiplied by 4 when the input value increases by 1. This means that the growth factor b is 4.
So, the function equation in sequence notation is w(t) = 60 * 4^(t-1).

b) the average temperature of the water in the system is 1527.
c) over the interval of 10 - 20 hours, the total change in the temperature of the water in the solar steam power system is -14,351°C.
a) g'(x) = 2 + [tex]\int\limits^x_0[/tex] ƒ'(t) dt
g'(-3) = -2
b) The absolute maximum value of g on the closed interval [-5, 5]=
10 + 2√7.
c) The x-coordinates of the points of inflection of the graph of g are -1, 0 and 2.
What is right Riemann sum formula?
The right Riemann sum formula uses the right-most value of each interval as the value of the function over that interval.
a) g(5) = 2(5) + [tex]\int\limits^5_0[/tex] ƒ(t) dt
= 10 + 2√7
g'(x) = 2 + [tex]\int\limits^x_0[/tex] ƒ'(t) dt
g'(-3) = 2 + [tex]\int\limits^3_0[/tex]ƒ'(t) dt
= 2 - (4 + 0)
= -2
b) The absolute maximum value of g on the closed interval [-5, 5]=
10 + 2√7.
This is because the highest value of ƒ(t) dt on the interval= 4√7, which occurs at x = 2.
The highest value of g is thus given by 10 + 2√7.
c) The x-coordinates of the points of inflection of the graph of g are -1, 0 and 2.
This is because ƒ'(t) dt is undefined at these points, so the second derivative of g is also undefined.
a) To evaluate the S'(t) dt, we need to calculate the area under the curve of the temperature data given in the table. To do this, we use the trapezoidal rule. This gives us the following:
[tex]\int\limits^10_0[/tex] S'(t) dt = [(142 + 210 + 254 + 280 + 274 + 268)/2] × 8
= 17,088
This means that over the interval of 0 - 10 hours, the average rate of change of the temperature is 17,088°C/hr.
This can be interpreted in the context of the problem as the average rate at which the temperature of the water in the solar steam power system is changing over the given time interval.
b) To approximate the average temperature of the water in the system using a right Riemann approximation, we need to calculate the area under the curve of the temperature data given in the table. We can do this using the right Riemann sum formula, which gives us the following:
Right Riemann Approximation = [(210 + 254 + 280 + 274)/4] × 6 = 1527
In this case, the right-most value of each interval is lower than the true average over that interval, so the approximation will be lower than the true average.
c) To determine the total change in the temperature of the system for the interval 10≤t≤20, we need to calculate the area under the curve of the equation S'(t)=-√2xe (√x²-100)/x.
This can be done using the definite integral of the equation, which gives us the following:
Total Change = ∫1020-√2xe (√x²-100)/x dx
= -14,351
This means that over the interval of 10 - 20 hours, the total change in the temperature of the water in the solar steam power system is -14,351°C.

A container built for transatlantic shipping is constructed in the shape of a right rectangular prism. Its dimensions are 4.5 ft by 11.5 ft by 10.5 ft. The container is entirely full. If, on average, its contents weigh 0.4 pounds per cubic foot, and, on average, the contents are worth $4.60 per pound, find the value of the container’s contents. Round your answer to the nearest cent.
Answers
The value of the container's contents is approximately $983.25
What is the value of the container's contents?To find value of the contents, we must calculate its volume first.
Volume = length x width x height
Volume = 4.5 ft x 11.5 ft x 10.5 ft
Volume = 534.375 cubic feet
The container is full and its contents have a volume of 534.375 cubic feet. If its contents weigh 0.4 pounds per cubic, then, total weight of the contents is:
= Volume x Weight per cubic foot
= 534.375 cubic feet x 0.4 pounds per cubic foot
= 213.75 pounds
If the contents are worth $4.60 per pound on average, then the total value of the contents is:
= Weight x Value per pound
= 213.75 pounds x $4.60 per pound
= $983.25.

The probability of surveying 100 randomly selected households and getting 4 or fewer tuned to 60 minutes is only 0.02%.
How to calculate the probabilityP(X <= 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)
P(X = k) = (100 choose k) * 0.078^k * (1 - 0.078)^(100-k)
P(X <= 4) = (100 choose 0) * 0.078^0 * (1 - 0.078)^(100-0) + (100 choose 1) * 0.078^1 * (1 - 0.078)^(100-1) + (100 choose 2) * 0.078^2 * (1 - 0.078)^(100-2) + (100 choose 3) * 0.078^3 * (1 - 0.078)^(100-3) + (100 choose 4) * 0.078^4 * (1 - 0.078)^(100-4)

I can't think of a reason why you'd need to use height or width when measuring a line on a graph. Besides if it were height, it'll just be the length of the line when vertical. And all generated graphed lines have the same width. You wouldn't need to measure it.

Algebra substitution y=-3x+5 2x+y=6
Answers
The solution to the system of equations y=-3x+5 and 2x+y=6 is (x,y) = (-1,8).
To solve the system of equations using substitution, we can substitute the expression for y in the second equation with the expression for y in the first equation:
2x + y = 6
2x + (-3x + 5) = 6 (substitute y = -3x + 5)
2x - 3x + 5 = 6
-x + 5 = 6
-x = 1
x = -1
Now that we have found the value of x, we can substitute it back into either of the original equations to find the value of y:
y = -3x + 5
y = -3(-1) + 5
y = 8
We can check our solution by verifying that it satisfies both equations:
y = -3x + 5 => 8 = -3(-1) + 5 => 8 = 8 (true)
2x + y = 6 => 2(-1) + 8 = 6 => 6 = 6 (true)

L = 8(0) + 120
L = $120.
When t = 1, the value of L is given by;
L = 8(1) + 120
L = $128.

Identifying the graph of the function g(x)?From the question, we have the following parameters that can be used in our computation:
f(x) = 3√x
The transformed function g(x) is given as
g(x) = 2f (x − 3)
In f(x) = 3√x , we have

Multiply both sides by 2
So, we have
