Good evening!

In this question, we were asked to solve for the sales tax of the laptop that Youlanda bought.

We were given:
- Cost of laptop: $459

- Sales Tax: 7.5%

In order to find the amount Youlanda paid for the sales tax, we would multiply the cost of the laptop ($459) by the sales tax (0.075):

Calculate:
459 × 0.075 = 34.425

Your answer would be: $34.425

Longitud = L Ancho = A
2A + 2L = 54
L = 2A Sustituir este valor por L en la primera ecuación:
2A + 2(2A) = 54
2A + 4A = 54
6A = 54
A = 9
También porque L = 2A,
L = 2(9) = 18

Answer:

The p-value for this test is 0.22065.

Step-by-step explanation:

We are given that a national study report indicated that 20.9% of Americans were identified as having medical bill financial issues.

A news organization randomly sampled 400 Americans from 10 cities and found that 90 reported having such difficulty.

Let p = proportion of Americans who were identified as having medical bill financial issues in 10 cities.

SO, Null Hypothesis, $H_0$ : p $\leq$ 20.9% {means that % of Americans who were identified as having medical bill financial issues in these 10 cities is less than or equal to 20.9%}

Alternate Hypothesis, $H_A$ : p > 20.9% {means that % of Americans who were identified as having medical bill financial issues in these 10 cities is more than 20.9% and is more severe}

The test statistics that will be used here is One-sample z proportion statistics;

T.S. = $\frac{\hat p-p}{{\sqrt{\frac{\hat p(1-\hat p)}{n} } } } }$ ~ N(0,1)

where, $\hat p$ = sample proportion of 400 Americans from 10 cities who were found having such difficulty = $\frac{90}{400}$ = 0.225 or 22.5%

n = sample of Americans = 400

So, test statistics = $\frac{0.225-0.209}{{\sqrt{\frac{0.225(1-0.225)}{400} } } } }$

= 0.77

Now, P-value of the test statistics is given by the following formula;

P-value = P(Z > 0.77) = 1 - P(Z $\leq$ 0.77)

= 1 - 0.77935 = 0.22065

HELP ASAP What is the area of this polygon on a coordinate plane?

iren2701 [21]

Answer:

Step-by-step explanation:

One way to find the area of any polygon is to find areas of all of its inside sections and then adding them together. For example, if I had a polygon made of a square stuck to a triangle, I could calculate the area of the polygon by adding the area of the square to the area of the triangle.

Mr. Grayson owns a wood company that sells trees, wood materials, and specialty items created from wood. (Score for Question 1:

BigorU [14]

Question 1:
A) No; 9.3 or 20.6.
B) Yes, because the triangles are similar.
C) No, because the triangles will not necessarily be similar.

There is not enough information to answer Questions 2 or 3.

Explanation for Question 1:
A) We are not told which side is the longest, so these two sides could be placed anywhere in the Pythagorean theorem. They could either be both legs, or one could be the hypotenuse:

Hypotenuse: 13² + b² = 16²
169 + b² = 256
169 + b² - 169 = 256 - 169
b² = 87
b = √87 = 9.3

Both legs: 13² + 16² = c²
169 + 256 = c²
425 = c²
√425 = c
20.6 = c

B) The two triangles will be similar, since each pair of corresponding sides will have the same ratio (2, since it is doubled). Similar triangles have the same angle measures, so this must also be a right triangle.

C) Simply adding a value to each side will not preserve similarity. For example, if we had a triangle with sides 3, 4, and 5, adding 2 to each side would give us 5, 6 and 11. These do not have the same ratios; 3/5 is not the same as 4/6 or 5/11.
