$\frac{f(x+h)-f(x)}{h}=\frac{(x+h)^2-3-(x^2-3)}{h}=\\\frac{x^2+2xh+h^2-3-x^2+3}{h}=\frac{2xh+h^2}{h}=\\\frac{h(2x+h)}{h}=2x+h$

A public health department wants to determine the rate that parents of teen boys are choosing to vaccinate their sons for HPV wi

viktelen [127]

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

The sample size is $n = 64$

The proportion that choose to vaccinate the teen boys is $\r p = 0.12$

considering the first statement

The 95% confidence interval is 12% ± the margin of error*standard deviation is false because

The 95% confidence interval is is %12 ± the margin of error

considering the second statement

The confidence interval should not be calculated due to the small sample size is true because from the central limit theorem

np = 64 * 0.12 = 7.68

and this value is less than 10 hence the confidence interval should not be calculated

considering the third statement

A 99% confidence interval will be smaller than the 90% confidence interval is false

This is because as the confidence level increase (for example from 90% to 99%) the margin of error increase which increases the confidence interval

Hence missing value in the solution to the equation is:(-5,2)

Step-by-step explanation:

We are given the equation:

$x-5y= -15$

and we need to complete the missing value in the solution to the equation

(-5,?)

Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)

So, x= -5, Now finding y:

Putting value of x in given equation:

$x-5y= -15\\-5-5y= -15\\-5y=-15+5\\-5y=-10\\y=-10/-5\\y=2$

So, value of y is 2

Hence missing value in the solution to the equation is:(-5,2)
