<h3>Answer: 2x+10 inches</h3>

Explanation:

There are 2 opposite sides that are x inches long, so they add to x+x = 2x

Then there are 2 opposite sides that are 5 inches long, which add to 5+5 = 10

Overall, the four sides add to 2x+10 inches

You could also apply the formula below

P = 2L+2W

P = 2x+2*5

P = 2x+10

That formula is the same as P = 2(L+W)

Answer:

96.8 percent

Step-by-step explanation:

You can cut off two zeros from both numbers to compare 1000 to 32.

The difference is 968, and the original is 1000.

So you divide 968 by 1000 to get 0.968 which is equal to 96.8 percent.

Monique is planning the locations for three exhibit areas at the festival. She drew a model of one of the exhibit areas as shown

WITCHER [35]

The second area was translated 1 unit right and 6 units down to form the third exhibit area.

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, dilation and rotation.

Translation is the movement of a point either up, down, left or right.

Given the translation (x,y)→(x+1,y+6). Hence:

The second area was translated 1 unit right and 6 units down to form the third exhibit area.

What’s the slope 3y=15-6x

Vera_Pavlovna [14]

Answer:

-2

Step-by-step explanation:

Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:

(3y)/3 = (15 - 6x)/3

y = (15 - 6x)/3

y = 5 - 2x

Note the equation:

y = mx + b

m = slope

b = y-intercept

x & y = the point (x , y)

Note that the slope is directly next to x. -2 is your answer.

The Center for Medicare and Medical Services reported that there were 295,000 appeals for hospitalization and other Part A Medic

Ksivusya [100]

Answer:

(a) P (X = 0) = 0.006

(b) P (X = 1) = 0.0403

(d) P (X > 5) = 0.1664

Step-by-step explanation:

Let <em>X</em> = number of successful appeals.

The probability that an appeal is successful is, <em>p</em> = 0.40.

The sample size is, <em>n</em> = 10.

The random variable $X\sim Bin(n=10, p=0.40)$ .

The probability function of a Binomial distribution is:

$P(X=x)={n\choose x}p^{x}(1-p)^{n-x}$

(a)

The probability that none of the appeals is successful is:

$P(X=0)={10\choose 0}(0.40)^{0}(1-0.40)^{10-0}\\=1\times1\times0.0060466176\\=0.0060466176\\\approx0.006$

Thus, the probability that none of the appeals is successful is 0.006.

(b)

The probability that exactly one of the appeals will be successful is:

$P(X=1)={10\choose 1}(0.40)^{1}(1-0.40)^{10-1}\\=10\times0.40\times0.010077696\\=0.040310784\\\approx0.0403$

Thus, the probability that exactly one of the appeals will be successful is 0.0403.

(c)

The probability that at least two of the appeals will be successful is:

$P(X\geq 2)=1-P(X$

Thus, the probability that at least two of the appeals will be successful is 0.9537.

(d)

The probability that more than half of the appeals will be successful is:

$P(X> 5)=1-P(X\leq 5)\\=1-P(X=0)-P(X=1)-P(X=2)-P(X=3)-P(X=4)+P(X=5)\\=1-[{10\choose 0}(0.40)^{0}(1-0.40)^{10-0}]-[{10\choose 1}(0.40)^{1}(1-0.40)^{10-1}]\\-[{10\choose 2}(0.40)^{2}(1-0.40)^{10-2}]-[{10\choose 3}(0.40)^{3}(1-0.40)^{10-3}]\\-[{10\choose 4}(0.40)^{4}(1-0.40)^{10-4}]-[{10\choose 5}(0.40)^{5}(1-0.40)^{10-5}]\\=1 - 0.006-0.0403-0.1209-0.2150-0.2508-0.2006\\=0.1664$

Thus, the probability that more than half of the appeals will be successful is 0.1664.
