The height h and collar size c , both in centimeters, measured from a sample of boys were used to create the regression line cˆ=−94+0.9h . The line is used to predict collar size from height, both in centimeters, for boys’ shirt collars. Which of the following has no logical interpretation in context?
Answers
Answer:
The C=intercept of the regression line
Step-by-step explanation:
The slope of the regression line has a logical interpretation as the average rate of change in collar size for a 1cm increase in height.
A linear regression is represented as [tex]^\wedge y = mx + c[/tex]
The option that has no logical interpretation is: E The c-intercept of the regression line
From the question, we have:
[tex]^\wedge c = 94 + 0.9h[/tex]
Using the above representation of a regression line [tex]\wedge y = mx + c[/tex]
[tex]m \to[/tex] the slope
[tex]c \to[/tex] the y-intercept
By comparing [tex]\wedge y = mx + c[/tex] to [tex]^\wedge c = 94 + 0.9h[/tex]
[tex]0.9 \to[/tex] slope
[tex]94 \to[/tex] the y-intercept
While [tex]^ \wedge c[/tex] and [tex]h[/tex] are the variables (i.e. collar size and height)
From the list of given options (see attachment), the option that has no logical interpretation is:
E. The c-intercept of the regression line
This is because c does not represent the intercept of [tex]^\wedge c = 94 + 0.9h[/tex]

How are proportional quantities described by equivalent ratios?
Answers
Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin. ... Describe situations in which opposite quantities combine to make 0.
Proportional quantities are described by equivalent ratios as shown below
[tex]\frac{p_1}{q_1} = \frac{p_2}{q_2}[/tex]
Let the two proportional quantities be p and q
If p and q are proportional, then [tex]p \alpha q[/tex]
Introducing a proportionality constant (k)
[tex]p = kq\\\\k = \frac{p}{q}[/tex]
Since the two quantities are proportional, the ratio of initial values will be equal to the ratio of their final values.
That is [tex]\frac{p_1}{q_1} = \frac{p_2}{q_2}[/tex]
Therefore, proportional quantities are described by equivalent ratios as shown below
[tex]\frac{p_1}{q_1} = \frac{p_2}{q_2}[/tex]

Answers
Answer:
The two fractions equivalent to eachother are 2/3 and 6/9
Step-by-step explanation:
These fractions are equivalent because 6/9 can be reduced into 2/3. Also 6 is a multiple of 2 and 9 is a multiple of 3.
The fractions 2/3 and 6/9 are equivalent to each other after simplifying the fractions.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
The three fractions are:
2/3, 4/5, 6/9
The above fractions can be written in the form of decimals:
After dividing:
2/3 = 0.666
4/5 = 0.8
6/9 = 0.66
The fractions 2/3 and 6/9 are equivalent to each other because its decimal forms are equal.
Or
2/3 = 6/9
Thus, the fractions 2/3 and 6/9 are equivalent to each other after simplifying the fractions.

Is 3125 a perfect cube ? If not find the smallest number by which 3125 must be multiplied so that the product becomes a perfect cube.
Answers
Answer:
Yes it is
Step-by-step explanation: 3125 is a prefect cube
Answer:
5
Step-by-step explanation:
3125 is not a perfect cube.
The cubes around it are 14^3=2744 and 15^3=3375.
It seems like the only way to find the smallest number to multiply 3125 to make it a perfect cube is to guess and check.
3125*2=6250 cube root is 18.4
3125*3=9375 cube root is 21.08
3125*4=12500 cube root is 23.2
3125*5=15625 cube root is 25, which makes it a perfect cube.
You have to multiply by 5 to make 3125 a perfect cube.

a packing machine fills boxes at a constant rate of 1/2 box every 1/5 of a minute what is the number of boxes per minute that the machine packs
Answers
Answer:
2½ boxes
Step-by-step explanation:
From the question given above,
We understood that the machine fills 1/2 box in 1/5 min.
Thus, we can simply obtain the number boxes the machine will fill by doing the following:
The machine fills 1/2 box in 1/5 min.
Therefore, the machine will fill y box in 1 min i.e
y box = (1/2 × 1) ÷ 1/5
y box = 1/2 ÷ 1/5
y box = 1/2 × 5/1
y box = 5/2 = 2½
Therefore, the machine fills 2½ boxes in a minute.
