*ANSWER FAST* What is the area of the polygon?

Lynn can type 60 words per minute. If she types for 30 minutes, how many words does she type in all?

Crazy boy [7]

Answer:1800 words

Step-by-step explanation:

Multiply how many words per minute she types by how many minutes she types. In this case 60x30=?. The easy way to do this is drop the 2 zeros and do 6x3=18. In the original equation we dropped the 2 zeros. Now we add them back on the back of the 18 and get 1800.

I need help ASAP I will give brainliest if correct

alexdok [17]

Part 1)
we know that
the property of cyclic quadrilaterals for which opposite angles are supplementary
then
m∠A°+43°=180°------------> m∠A=180°-43°=137°

the answer is m∠A=137°

Part 2) Quadrilateral ABCD is inscribed in a circle. What is the measure of angle A?

we know that
the property of cyclic quadrilaterals for which opposite angles are supplementary
then:
m∠A+m∠C=180∘
(2x+9)+(3x+1)=180---------------> 5x+10=180
x=(180-10)/5=34

m∠A=2x+9-------------> 2*34+9=77°

the answer is m∠A=77°

Which function does not have a vertical asymptote? A) y=(x) /(1-x²) . B) y=(5x) /(1-2x²) . C) y=(5x-1) /(3+x^2) . D) (5x) /(x+x²

A function has a vertical asymptote $x=a$ at point a, where the denominator becomes equal to 0.

A. The denominator of the function $f(x)=\dfrac{x}{1-x^2}$ turns into 0 at $x=1$ or $x=-1.$ Then $x=1$ and $x=-1$ are two vertical asymptotes of this function.

B. The denominator of the function $f(x)=\dfrac{5x}{1-2x^2}$ turns into 0 at $x=\sqrt{\frac{1}{2}}$ or $x=-\sqrt{\frac{1}{2}}$ Then $x=\sqrt{\frac{1}{2}}$ and $x=-\sqrt{\frac{1}{2}}$ are two vertical asymptotes of this function.

C. The denominator of the function $f(x)=\dfrac{5x-1}{3+x^2}$ never turns into 0, then this function hasn't any asymptotes.

D. The denominator of the function $f(x)=\dfrac{x}{x+x^2}$ turns into 0 at $x=0.$ Then $x=0$ is vertical asymptote of this function.

Answer: correct choice is C.

In the United States, 36 percent of the people have a blood type that is A positive. From a random sample of 150 people from Nor

djverab [1.8K]

Answer:

The standard deviation used in the test statistic is 0.04.

Step-by-step explanation:

A single proportion z-test can be used to determine whether the proportion of people in Norway with a blood type of A positive is different from that in the United States.

The proportion of people in Norway with a blood type of A positive is 36% or 0.36.

The hypothesis can be defined as:

H₀: The proportion of people in Norway with a blood type of A positive is 36%, i.e. p = 0.36.

Hₐ: The proportion of people in Norway with a blood type of A positive is different from 36%, i.e. p ≠ 0.36.

The test statistic is:

$z=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}$

The information provided is:

p = 0.36

n = 150

Compute the standard deviation used in the test statistic as follows:

$\sigma=\sqrt{\frac{p(1-p)}{n}}$

$=\sqrt{\frac{0.36\times (1-0.36)}{150}}$

$=\sqrt{0.001536}\\=0.03919184\\\approx 0.04$

Thus, the standard deviation used in the test statistic is 0.04.

What's the degree of the polynomial? P(x)= 7x^7+2x^5+7x+7

mario62 [17]

Answer:

7

General Formulas and Concepts:

Degree of Polynomial is determined by the highest power

Step-by-step explanation:

Step 1: Define function

P(x) = 7x⁷ + 2x⁵ + 7x + 7

Step 2: Identify

7x⁷ is the largest term.

Has the highest power
Therefore, highest degree
