The equation y= 94.38x+ 38.17 fits the scatterplot of the values for stock
ABC over the past month with an value of 0.9948. How much do you think
ABC will be worth at x= 47 days?
Answers
The value of the stock ABC over a period of 47 days is $4474.03.
What is a scatterplot?
A scatterplot is used to show the relationship between two variables. The variables are plotted on Cartesian axes.
First, we must determine the fitness of the line to show if it is linear. We can get this from r^2 = (0.9948)^2 = 0.9896. This value is close to one hence the line is linear.
Thus;
y= 94.38x+ 38.17 and x = 47 hence
y= 94.38(47)+ 38.17
y = $4474.03

BD bisects ABC if ABC=6x+58 find ABD
Answers
The measure of the angle ABD is (3x + 29)
What is Bisecting angles?Bisecting angles is the process of dividing an angle into two congruent angles. In geometry, an angle bisector is a line or ray that divides an angle into two equal parts.
When an angle is bisected, each of the two angles formed is called a half-angle or bisector angle, and the point where the angle is bisected is called the vertex of the angle.
Here we have
BD bisects ABC and ∠ABC = 6x+58
When a straight bisect an angle then the measure of the resultant 2 angles will be equal in measure
Here BD bisected ABC
The resultant angles will be ∠ABD and ∠DBC
Hence,
=> ∠ABC = ∠ABD + ∠DBC
=> ∠ABC = ∠ABD + ∠ABD [ Since two angles are equal
=> ∠ABC = 2∠ABD
From the given data,
=> 6x + 58 = 2∠ABD
=> 2 ∠ABD = 2(3x + 29)
=> ∠ABD = (3x + 29)
Therefore,
The measure of the angle ABD is (3x + 29)

A bus company took a tour bus on the ferry when there were 30 people aboard. The ferry charged the bus company $180. The following week, the bus had 50 people on board and the ferry charged them $220. How much is the "base rate" for the empty bus? hint: look at the difference between number of people and cost to get cost per person and then cost without people
How much does each person cost?
Write an equation to show cost, c, of a bus with x number of people on it
Answers
Answer:
Base rate: $120
Rate: $2 per person
Equation: f(x)=2x+120
Step-by-step explanation:
If 30 people cost $180 and 50 people cost $220, the charge for 20 extra people is $40. This means, \(\frac{220-180dollars}{50-30people}=\frac{40dollars}{20people}=2\frac{dollars}{person}\).
These values correspond to a base rate for the bus of $120.
The function for the cost per bus with x number of people on it would be:
\(f(x)=2x+100\)
This can be checked by using the values given in the problem:
\(f(30)=2(30)+120=180\\f(50)=2(50)+120=220\)
The base rate of $120 and $2 per person satisfies the given equation and established values.

Answers
49 is the smallest possible value of x.
Given: x, y, and z are three perfect square numbers.
What is the least x that can be?
Currently, we have three numbers by the stipulation:
x > y > z > 0
and AP has these figures.
Let's now list every perfect square from 1 to 10 in the following order: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
As a result, we can observe that 25 is equal to the product of 1 plus 49.
The possible outcomes are 1, 25, and 49.
If x = 49 and z = 1, then
x + z / 2 = y
49 + 1 / 2 = y
y = 50 / 2
y = 25
Y is therefore 25 and X is 49.
As a result, 49 is the lowest value of x that can exist.

When sample size increases:____.
A. Standard deviation of the sample mean increases.
B. Confidence interval remains the same.
C. Confidence interval increases.
D. Confidence interval decreases.
Answers
Answer:
D. Confidence interval decreases.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \(\mu = p\) and standard deviation \(s = \sqrt{\frac{p(1-p)}{n}}\)
When sample size increases:
The standard deviation of the sample mean is:
\(s = \frac{\sigma}{\sqrt{n}}\)
That is, it is inversely proportional to the sample size, so if the sample size incerases, the standard deviation decreases, and so does the confidence interval.
This means that the correct answer is given by option D.

Answers
Answer:
Therefore, you need 2600 pounds of 35% supplement and 1300 - 2600 = -1300 pounds of 10% ration.
Step-by-step explanation:
The unknown variable is x, which is the amount of 35% supplement needed. The other expressions are derived from the given information and the fact that the total amount of solution is 1300 pounds.
The equation from the fourth column is:
0.35x + 0.10(1300 - x) = 0.25(1300)
Solving for x, we get:
x = (0.25(1300) - 0.10(1300)) / (0.35 - 0.10) x = 650 / 0.25 x = 2600

The measure of angle x on the straight line is 130 degrees.
What is the measure of angle x?The sum of interior angles in a triangle equals 180 degrees.
To determine the value of x, we first determine its suplemetary angle x .
Hence:
40 + 90 + ( suplemetary angle of x ) = 180
Solve for the suplementary angle:
130 + ( suplemetary angle of x ) = 180
Suplementary angle of x = 180 - 130
Suplemetary angle of x = 50 degree
Now, we can find the measure of angle x.
Note that, sum of angles on a straight line equals 180 degree.
Hence:
x + ( suplemetary angle of x ) = 180
x + 50 = 180
Solve for x
x = 180 - 50
x = 130 degrees.
Therefore, the value of x is 130 degrees.

How do the average rate of change for the functions f(x)=2x2 and g(x)=3x2 over the interval -3 less than or equal to x less than or equal to 4
Answers
To find the average rate of change of f(x) = 2x^2 over the interval [-3,4], we first need to find the change in the function over that interval.
f(4) - f(-3) = 2(4)^2 - 2(-3)^2 = 32 - 18 = 14
Next, we need to find the change in x over the interval:
4 - (-3) = 7
So, the average rate of change of f(x) over the interval [-3,4] is:
14/7 = 2
To find the average rate of change of g(x) = 3x^2 over the same interval, we follow the same steps:
g(4) - g(-3) = 3(4)^2 - 3(-3)^2 = 48 - 27 = 21
4 - (-3) = 7
So, the average rate of change of g(x) over the interval [-3,4] is:
21/7 = 3
Therefore, the average rate of change of f(x) over the interval [-3,4] is 2, and the average rate of change of g(x) over the same interval is 3.

The formula for y in terms of x is y=160/x^2.
We are given that;
y = 20 when t=4
And t = 8 when x = 2
Now,
To find the value of k by using the fact that y = 20 when t = 4:
20=k⋅4
k=5
Also, y=5t
Next, we use the fact that t is inversely proportional to the square of x. We can write:
t=x2k
where k is a constant of proportionality. We can find the value of k by using the fact that t = 8 when x = 2:
8=22k
k=32
Now we know that:
t=x232
Substituting this into the equation for y:
y=5t=5⋅x232=160/x^2

Answers
The area of the trapezium will be 168 ft².
What is a trapezium, exactly?
Trapezoids have two parallel sides and two oblique sides. Another term for it is a trapezium. A trapezoid is a four-sided closed form with a space-filling perimeter. It is a 2D figurine, not a 3D figure. The bases of a trapezoid are parallel to one another. Legs are non-parallel sides, sometimes referred to as lateral sides and height is the distance between the parallel sides.
The area of a trapezium is equal to 1/2*(a+b)*h.
where h is the distance or height between two parallel lines
Lines a and b are parallel.
Now,
As we can decompose given trapezium into a rectangle with length=18 ft and breadth=8 ft and a triangle with base=6 ft and height=8 ft.
Then area of trapezoid=area of rectangle + area of triangle
=l*b+1/2*b*h
=18*8+1/2*6*8
=144+24
=168 ft²
Hence,
The area of the trapezium will be 168 ft².
