Area of quilt, Q= 60^2\, in^2=3600\,in^2
Area of purple square, P = (x-5)^2\, in^2
Area of white area 
= Q-P
= 3600-(x-5)^2\, in^2
=3600-x^2+10x-25\, in^2
=3575-x^2+10x\, in^2

(7 points) Cars arrive at a toll both according to a Poisson process with mean 80 cars per hour. If the attendant makes a two-mi
saveliy_v [14]

Answer:

The probability that at least 1 car arrives during the call is 0.9306

Step-by-step explanation:

Cars arriving according to Poisson process - 80 Cars per hour

If the attendant makes a 2 minute phone call, then effective λ = 80/60 * 2 = 2.66666667 = 2.67   X ≅ Poisson (λ = 2.67)

Now, we find the probability: P(X≥1)

P(X≥1) = 1 - p(x < 1)

P(X≥1) = 1 - p(x=0)

P(X≥1) = 1 - [ (e^-λ) * λ^0] / 0!

P(X≥1) = 1 - e^-2.67

P(X≥1) = 1 - 0.06945

P(X≥1) = 0.93055

P(X≥1) = 0.9306

Thus, the probability that at least 1 car arrives during the call is 0.9306.

Maya has to type a document of 2160 words. The graph below shows her initial progress. If
aksik [14]

The time it takes to type the document increases proportionately to the

number of words in the document.

  • The time it would take to type the document is; <u>36 minutes</u>

Reasons:

From the possible figure from a similar question, we have;

The points on the graph are; (0, 0), (1, 60), (2, 120), (3, 180), (4, 240)

The graph is a straight line, therefore, given that the starting point is at the origin, using the points, (0, 0), (1, 60), we have;

The slope of the graph = 60

The y-intercept = 0

The equation that represents the proportional relationship shown on the graph is therefore;

y = 60·x

Where;

y = The number of words

x = The time it takes to type the document

The time it would take Maya to type the document of 2,160 words is given as follows;

2,160 = 60·x

Therefore;

\displaystyle Time, \ x = \frac{2,160 \ words}{60 \ words/minute}  = \mathbf{36 \ minutes}

The time it would take Maya to type the document is x = <u>36 minutes</u>

The function f(x) is given by the set of ordered pairs.
My name is Ann [436]
Answer: f(0) = 6.

Explanation:

Ther ordered pairs are: (x,y) or (x, f(x) )

So, (1,0) means that f(1) = 0 which denies the fourth choice.

(-10,2) means that f(-10) = 2 which denies the first choice

(0,6) means that f(0) = 6, which is the third choice. So, that is the true equation.

Person BMI Total Cholesterol
dlinn [17]
By using the arithmetic sequence, the difference between every other age is 12.98 (interval is 2). Example: 20 and 22 has 157.87 and 170.85 respectively which has the mentioned difference. Hence, if we calculate for the person who has a BMI of 35, then we add 12.98 to 235.75 plus the half which is 6.49. The total is <span>255.22. The answer is C.</span>
