Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

$y=kx$

The number 'k' is called the constant of proportionality.

Given the equation

$y=3.50x$

$y=kx$

$k=3.50$ ∵ $y=kx$

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.

5.
-4n+ 7+ 2n= 1
⇒ (-4n+ 2n)+ 7= 1 (combine like terms)
⇒ -2n= 1-7
⇒ -2n= -6
⇒ n= -6/(-2)
⇒ n= 3

Final answer: B. 3~

6. 4(y-4)= 8
⇒ y-4= 8/4
⇒ y-4= 2
⇒ y= 2+4
⇒ y= 6

Final answer: D. 6~

12345 [234]

Answer:

The interval 52% to 58% is based on a procedure that includes the true population value 95% of the time.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

95% confidence

We are 95% sure that the interval contains the true mean/proportion, and thus, the correct option is:

The interval 52% to 58% is based on a procedure that includes the true population value 95% of the time.
