Which equation has a constant of proportionality
To 1/2?
I have attached an image showing the complete question with the answer options.
Answer:
Option C: y = (3/6)x
Step-by-step explanation:
We are told that the constant of proportionality is 1/2.
Now, in constant of proportionality we use the formula;
y = kx
Where k is the constant of proportionality.
Thus the equation is;
y = ½x
Now, since ½ is a reduced form, we can write ½ as 2/4 or 3/6 and so on.
From the options, we see an equation with; y = (3/6)x
Thus,it's the correct one as when broken down, 3/6 gives ½

Use the angle bisector theorem. In this case, it says
3 / (8 - y) = 9 / y
Solve for y :
3y = 9 (8 - y)
3y = 72 - 9y
12y = 72
y = 6
HELPPP DUE IN 8 MINS!! There are many cylinders with a height of 9 inches. Let r represent the radius in inches and V represent the volume in cubic inches. Is there a linear relationship between the radius and the volume of
these cylinders?
The solution is,
R V
1 9π in³
2 36π in³
3 81π in³
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
For, r = 1
V = π(1)²9
= 9π in³
For, r = 2
V = π(2)²9
= 4*9π in³
= 36π in³
For r = 3
V = π(3)²9
= 9*9π in³
= 81π in
The solution is,
R V
1 9π in³
2 36π in³
3 81π in³

Consider random samples of size 50 from a population with proportion 0.35.
Find the mean and standard error of the distribution of sample proportions.
Round your answer for the mean to two decimal places, and your answer for the standard error to three decimal places.
Answer:
The mean is [tex]\mu_{\^ p } = p = 0.35[/tex]
The standard error is [tex]SE = 0.06745[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 50
The population proportion is [tex]p = 0.35[/tex]
Generally given that the sample size is large enough , then the mean of the distribution is mathematically represented as
[tex]\mu_{\^ p } = p = 0.35[/tex]
Generally the standard error of the distribution is mathematically represented as
[tex]SE = \sqrt{\frac{p (1- p )}{n} }[/tex]
=> [tex]SE = \sqrt{\frac{0.35 (1- 0.35 )}{50} }[/tex]
=> [tex]SE = 0.06745[/tex]

Answer:
98
Step-by-step explanation:
=====================================================
There are two ways to find the answer
-----------------------
Method 1
Multiply the length and width by the scale factor
10*3.5 = 35
4*3.5 = 14
The new larger rectangle is 35 inches by 14 inches
Add up the four sides: 35+14+35+14 = 98
The perimeter of the larger rectangle is 98 inches
-----------------------
Method 2
We can use the formula P = 2(L+W) to get the perimeter of the original rectangle
P = 2(10+4)
P = 2*14
P = 28
The original rectangle has perimeter 28 inches.
Or you could note how 10+4+10+4 = 28
Multiply this with the scale factor to get 28*3.5 = 98 inches
Triangle abc is similar to triangle def. which proportion can be used to find the length of DE on centimeters (please leave a small explanation)
Answer: DE=12
Step-by-step explanation:
ABC similar to DEF
That means that AB corresponds to DE , AC to DF and BC to EF
So AB/DE=AC/DF=BC/EF=5/15=3/9=1/3
So 4/DE=1/3
=>DE=12

If a certain machine makes electrical resistors having a mean resistance of 40 ohms and a standard deviation of 2 ohms, what is the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms?
Answer:
The probability is [tex]P(\= X < 40.4) = 0.84134[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu =40 \ \Omega[/tex]
The standard deviation is [tex]\sigma = 2 \ \Omega[/tex]
The sample size is n = 25
The combined resistance is [tex]\sum x_i = 1010 \ \Omega[/tex]
Generally the sample mean is mathematically represented as
[tex]\= x = \frac{\sum x_i }{n}[/tex]
=> [tex]\= x = \frac{1010 }{25}[/tex]
=> [tex]\= x = 40.4 \ \Omega[/tex]
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_{x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_{x} = \frac{ 2 }{\sqrt{25} }[/tex]
=> [tex]\sigma_{x} = 0.4[/tex]
Generally the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms is mathematically represented as
[tex]P(\= X < 40.4) = P( \frac{\= X - \mu }{\sigma_{x }} < \frac{ 40.4 - 40 }{0.4} )[/tex]
[tex]\frac{\= X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ \= X )[/tex]
[tex]P(\= X < 40.4) = P( Z < 1 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1 is
[tex]P(\= X < 40.4) = P( Z < 1 ) = 0.84134[/tex]
[tex]P(\= X < 40.4) = 0.84134[/tex]
