The correct interpretation regarding the confidence interval is that we are 95% confident that the mean number of words used in all papers is between 20,995 and 22,905.
What is the interpretation of a x% confidence interval?It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b
In this problem, the 95% confidence interval for the number of words in the sample of 25 papers is (20,995, 22,905), hence the interpretation is that we are 95% confident that the mean number of words used in all papers is between 20,995 and 22,905.

What is the equation of the line that passes through the point (-1,9) and is parallel to the line y=-5x+7?
Answer:
Y=5x+14
Explanation:
here, x=-1 y= 9
the equation of the line in slope intercept form is
y=mx+b
the slope(m)= 5
y intercept (b)= 7
note that slope of parallel lines are the same
then the equation
y= mx+b
substituting
9= 5(-1)+b
9 = -5+b
9+5 =b
14 = b
b= 14
therefore, y intercept of the parallel line will be 14.
finally, the equation of the parallel line will be
Y= 5x+14

A wealthy man just died and left his pet dogs the following estate: $20,000 per year for the next 11 years with the first cash flow today. at a discount rate of 4. 2%, what is the doggy estate worth in today's dollars?
The concept of present value lets us know that the doggy estate worth in today's dollars is $180614.80
What is the present value of the doggy estate worth?The concept of present value is significant because it enables investors to determine whether the amount they pay for an investment is reasonable. The present value of a future cash flow defines how much it is worth in today's value.
From the given information:
The annual cashflow C = $20,000Interest rate (i) = 4.2% = 0.042Number of period (n) = 11Thus, the present value of the doggy estate can be calculated by using the formula;
[tex]\mathbf{PV = C \times \Big [ \dfrac{1 - \dfrac{1}{(1+i)^n}}{i}\Big] \times (1+i)}[/tex]
[tex]\mathbf{PV = 20000 \times \Big [ \dfrac{1 - \dfrac{1}{(1+0.042)^{11}}}{0.042}\Big] \times (1+0.042)}[/tex]

The sequence of transformation is:
a dilation with center (0, 0), a scale factor 2, and a reflection across the y-axis
How to determine the sequence of transformation?The coordinates are given as:
p = (-1, 1)
q = (-2, 3)
r = (-2.5, 1)
p' = (2 , 2)
q' = (4, 6)
r' = (5, 2)
Start by reflecting the triangle pqr across the y-axis.
The transformation rule is:
[tex](x,y) \to (-x,y)[/tex]
So, we have:
p = (1, 1)
q = (2, 3)
r = (2.5, 1)
Dilate the resulting by a scale factor of 2 with the center of (0, 0)
The transformation rule is:
(x,y) = 2(x,y)
So, we have:
p' = (2 , 2)
q' = (4, 6)

A n example of Lesson 16.2 modeling exponential growth and decay is find out if y =5(2)ˣ is exponential growth or decay.
How do you know an exponential growth or decay?One can know if a function is an exponential growth or decay when it has a as positive and b is said to be greater than 1 (to be exponential growth).
If a is said to be positive and b is said to be lower than 1 but when it is also greater than 0, we can say that it is an exponential decay.
From the above, y =5(2)ˣ is an exponential growth because the base is said to be greater than 1 and the exponent contain a positive notation.

Two skydivers of different masses jump from a plane. in three to five sentences, explain how their falls compare, including the effects of gravity, mass, and air resistance.
When a skydiver jumps out of a plane, the skydiver is said to accelerates down as a result of the force of gravity. No air resistance do acts in the upwards direction, and thus, the resultant force is said to be acting downwards.
Due to the above, the skydiver is known to moves or accelerates towards the ground.
How gravity and air resistance affect the motion of the skydiver?Note that before the parachute of a skydiver is opened, the air resistance is known to be more than the downward force of gravity.
The net force and the acceleration on the falling skydiver is said to be often upward. And as such, the upward net force on a downward falling object such as the skydiver would cause the diver to slow down.
