Twenty different statistics students are randomly selected. For each of them, their body temperature (C) is measured and their head circumference (cm) is measured. If it is found that r0, does that indicate that there is no association between these two variables? Choose the correct answer below. A. No, because if r0, the variables are in a perfect linear relationship. B. No, because while there is no linear correlation, there may be a relationship that is not linear. C. No, because r does not measure the strength of the relationship, only its direction. D. Yes, because if r0, the variables are completely unrelated.
Answer:
B. No, because while there is no linear correlation, there may be a relationship that is not linear.
Step-by-step explanation:
Relationships between variables are diverse and fitted model of a dataset for each of the models will usually differ. That is the lebl of association between variables for a linear model may differ and better than a quadratic model or an exponential may perform. For r = 0 ; this means no relationship exists between the variables, however , this is the information for the linear model, which clearly depicts that no assicitio exist for the linear fit. A model change could result in a differ and slightly or highly correlated R value.

Write a cosine function that has an amplitude of 5, a midline of 2 and a period of \frac{2\pi}{5} 5 2π .
Answer:
f(x) = 5*cos(5*x) + 2
Step-by-step explanation:
A general cosine function is written as:
f(x) = A*cos(ω*x) + M
where:
A is the amplitude
M is the midline
ω is the angular frequency.
In this case we know that:
The amplitude is 5, then A = 5
The midline is 2, then M = 2
The period is 2*pi/5
The relation between the angular frequency ω and the period T is:
ω = 2*pi/T
Then if the period is T = 2*pi/5, replacing that in the above equation we find that:
ω = 2*pi/T = 2*pi/(2*pi/5) = 5
ω = 5
Then the function is:
f(x) = 5*cos(5*x) + 2
The cosine function should be [tex]f(x) = 5\times cos(5\times x) + 2[/tex]
The calculation is as follows:
A general cosine function is written as:
[tex]f(x) = A\times cos(\omega\times x) + M[/tex]
where
A is the amplitude
M is the midline
ω is the angular frequency.
Here, in the given situation
The amplitude is 5, then A = 5
The midline is 2, then M = 2
The period is [tex]2\times \pi\div 5[/tex]
The relation between the angular frequency ω and the period T is:
[tex]\omega = 2\times \pi\div T[/tex]
Now Then if the period is [tex]T = 2\div \pi\div 5,[/tex] replacing that in the above equation we find that:
[tex]\omega = 2\times \pi\div T = 2\times \pi\div (2\times \pi\div 5) = 5[/tex]
ω = 5
Then the function is [tex]f(x) = 5\times cos(5\times x) + 2[/tex]

The length of the diagonal of a television is 30 inches and its width is 18 inches. Find the length of the television.
48 inches
36 inches
24 inches
12 inches
Answer:this his lil h
Step-by-step explanation:
The length of the television will be 24 inches. Then the correct option is C.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The length of the diagonal of a television is 30 inches and its width is 18 inches.
Then the length of the television will be
30² = 18² + L²
L² = 900 - 324
L² = 576
L = 24 inches
Then the correct option is C.

Answer:
(24,4,84)
Step-by-step explanation:
Since they restricted our domains to certain x values, we can find the range by plugging in the x values to find it y value or output.
[tex]f( - 2) = 5( { - 2}^{2} ) + 4[/tex]
[tex]5(4) + 4 = 24[/tex]
[tex]f(0) = - 5( {0}^{2} ) + 4 = 4[/tex]
[tex]5(4) {}^{2} + 4 = 84[/tex]
So our range is (24,4,84)
Answer:
f(x)=5x²+4
f(-2)=5×(-2)²+4
5×4+424f(0)=5(0)²+4
0+44f(4)=5×(4)²+4
5×16+484so the range of function{-2,0,4}is{24,4,85}

If the vertex of a parabola is (2,3), what is the axis of symmetry?
Answer:

Step-by-step explanation:
Two best friends, Pluto and Goofy, have very different hobbies. Pluto likes to skydive from a height of 24,568 feet. Goofy likes to scuba dive down to a depth of 124 feet. If they participate in their hobbies at the same time, how far apart will these friends be?
Answer:
They are 24, 692 feet aprart
Step-by-step explanation:
Let us assume at the instance we are measuring their position, that Pluto is at the highest point in the air, which is = 24,568 feet, and Goofy is at the lowest point of the sea (that he can go) = 124 feet.
Before we can proceed with the addition, we need to establish a datum, which will serve as the reference point from which the two distances are measured. This definitely is the sea level, because altitude and depth are usually measured above and below sea level.
Pluto's location to the sea level = 24,568 feet
Goofy's Location to the sea level = 124 feet
their distance apart = 24,568 feet + 124 feet =24, 692 feet apart
The two-dot plots below show the number of miles run by 14 students at the beginning and end of the school year.
Answer:
Step-by-step explanation:
From the dot plot of start of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 5
Range of the data set = 10 - 5
= 5 miles
From the dot plot of End of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 6
Range of the data set = 10 - 6
= 4 miles
The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.
