Nico has conducted an observational study to learn about how different personal experiences affect car purchases. nico surveyed 300 new car buyers at the auto mall and found that 75% of the buyers were shopping for the same model of a car they have owned before. what conclusion can nico make from his study?
The conclusion of the given study is that; There may be a link between .... but he cannot draw a cause-and-effect conclusion from an observational study.
What is the conclusion of the study?We are told that;
Number of new cars Nico surveyed = 300
Percentage of buyers that surveyed the new cars = 75% .
Thus, number of customers surveying this cars = 75% * 300 = 225 customers
If people are satisfied with their car's current company and brand and model,it means that they can also prefer the same thing again for the same better experience. Thus, the conclusion is that;
There may be a link between owning a model of a car and buying that model again, but he cannot draw a cause-and-effect conclusion from an observational study.

Evaluate the expression under the given conditions. cos(2theta); sin(theta) = − 5 13 , theta in quadrant iii
The value of the given trigonometric expression which is cos 2θ under the 3rd quadrant is; -119/169
What is the value of the trigoneometric ratio?We are given the trigonometric ratio;
sin θ = -⁵/₁₃
From trigonometric identities, we know that;
cos 2θ = 1 - 2sin²θ
Thus;
cos 2θ = 1 - 2(-⁵/₁₃)²
cos 2θ = 1 - 2(25/169)
cos 2θ = 119/169
since cos θ is negative in the third quadrant, then we have;l

A spool is on a horizontal surface (with friction) and pulled to the right with a thread attached to the center of the spool, so that the spool rolls without slipping. the spool has a mass of m, moment of inertia i, and a radius of r
The relationship between the magnitude of the force of tension and the force of friction is; Ff = (r/R)Ft
What is Rotational Acceleration?We are given;
mass of spool = M
Radius = R
moment of inertia = I.
Now, the spool is not moving and as such;
r < R which means there is net torque = 0
Thus;
Ff × R = Ft × r
>> Ff = (r/R)Ft
Finally, the angular acceleration is expressed as;
α = a/R

The length of Main St. between 5th Ave. and 6th Ave Round to the nearest hundredth is; 0.24 km
How to use triangle proportionality theorem?From the image attached, we are given that 5th Avenue is parallel to 6th avenue.
Now, Let the length of main street between 5th and 6th Avenue be x.
By using the triangle proportionality theorem, we have;
0.4/x = 0.5/0.3
Thus;
x = (0.4 * 0.3)/0.5
x = 0.24 km

Which example shows an interaction between the urinary system and the circulatory system?
The main interaction between the urinary system and the circulatory system is both of the following parts of the human body work for the kidney.
The human body is the collection of many systems like the cardiovascular system for the heart, the urinary system for filtering the body, the circulating system for movement, and so on. All these functions help the body to regulate the smooth functioning of the body.
When the blood enters the kidney through arteries they go through the tiny capillaries that are seen in the urinary system. The blood entered into the kidney later moves to nephrons, where the blood is purified with the help of filters.
The waste that is obtained after the purification of the blood is then transferred to the vital substance that absorbs the bloodstream. It helps the body to manage and control the level of pressure in the blood.
Here the job of the heart is to simultaneously send the oxygenated blood all around the body and send the unwanted, discharged waste to the kidney where it helps to observe the required elements from the waste and transpose it to the urinary system.
The main work of the circulating system is to transpose the oxygenated blood to every part of the cell and provide them with sufficient nutrients.
From this system it is understandable that the similarities between circulatory and urinary system is both of the parts functions to remove waste from the body.

Lesson 16.2 modeling exponential growth and decay answer key
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.

What is the female reproductive system?It is in charge of physically and biochemically promoting the encounter between the sperm and the ovules generated by a female.
This union occurs in the uterus and, once the cells have been fertilized, a zygote is generated which, after nine months of growth, will become a new human individual.
