Can i have help plz ..

Simplify 8g+9h-4g-5h include instructions plz

Monica [59]

You can only add/subtract LIKE TERMS ( the exact same variable part )
Think of adding apples and oranges ...

8g-4g + 9h-5h I grouped them like this so you can see the LIKE TERMS.
= 4g + 4h

Get it?

A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a ne

Evgen [1.6K]

Answer:

a. With 90% confidence the proportion of all Americans who favor the new Green initiative is between 0.6290 and 0.6948.

b. If the sample size is changed, the confidence interval changes as the standard error depends on sample size.

About 90% percent of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about 10% percent will not contain the true population proportion.

Step-by-step explanation:

We have to calculate a 90% confidence interval for the proportion.

The sample proportion is p=0.6619.

$p=X/n=370/559=0.6619$

The standard error of the proportion is:

$\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.6619*0.3381}{559}}\\\\\\ \sigma_p=\sqrt{0.0004}=0.02$

The critical z-value for a 90% confidence interval is z=1.6449.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_p=1.6449 \cdot 0.02=0.0329$

Then, the lower and upper bounds of the confidence interval are:

$LL=p-z \cdot \sigma_p = 0.6619-0.0329=0.6290\\\\UL=p+z \cdot \sigma_p = 0.6619+0.0329=0.6948$

The 90% confidence interval for the population proportion is (0.6290, 0.6948).

removable and nonremovable discontinuities in exercises 35–60, find the -values (if any) at which is not continuous. which of th

My name is Ann [436]

This prompt is about removable discontinuities. See the explanation below.

<h3>What is a removable discontinuity?</h3>

A removable discontinuity is a point in a graph where it is not linked but may be made so by filling in a single point.

It is also possible to define it as follows:

A discontinuity is detachable at x=a if the limit limxaf(x) exists and is finite. There are two kinds of removable discontinuities. At x=a, the function is undefined.

It should be noted that a non-removable discontinuity is one in which the limit of the function does not exist at a given point, i.e. lim xa f(x) does not exist.

<h3>What is the calculation justifying the above answer?</h3>

Part A: Where F(x) = 6/x

At x = 0
f(x) = 6/0 = ∞; Thus,

At x = 0

f(x) is not defined. It is correct to state therefore, that f is continuous for all real integers or number save "zero".

Hence, f(x) is continuous at each x ∈ R - {α}

Part B: Where F(x) = 4/(x-6)

At x = 6
F(x) = 4/(6-6)

= 4/0

= ∞;

Thus, f (x) is not defined.

We can state therefore that F is continuous at x ∈ R - { α}

Part C: Where F (x)

F(x) = x² - 9

For each C∈R,

F(c) = C² = 9

Thus, F(x) here is defined and continuous. That is F(x) is continuous at x ∈ R

Part D: Where F(x) x² - 4x + 4

With respect to every C ∈ R,

F(c) = C² - 4c + 4
In this instance as well, F(c) is defined and continuous.

Thus, F(x) in this case is continuous for all X ∈ R
