An article claimed that only 38\88, percent of hotel visitors used the alarm clock provided. A hotel manager wanted to see whether that proportion applied to the hotel where she worked, so she took a random sample of 700700700 of the approximately 10{,}00010,00010, comma, 000 visitors to the hotel one month and checked whether they used their room alarm clock. Of the sampled visitors, only 35\55, percent used the alarm clock. Assuming that the article's 38\88, percent claim is also the true proportion for visitors to the hotel, what is the approximate probability that less than 35\55, percent of the sample used the alarm clock

Answers

Answer 1

Answer: P(p<0.35) = 0.05

Step-by-step explanation:

Khan told me

Answer 2

The approximate probability that less than 355 of the same used the alarm clock will be equal to 0.0485.

What is Probability?

Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.

As per the given information given in the question,

P = 0.38

Q = 1 - P = 1 - 0.38 = 0.62

n = 700 and sample proportion, p = 0.35

Use the formula given below,

z = (p - P)/√(PQ/n)

z = (0.35 - 0.38)/√(0.38 × 0.62)/700

z = -0.03/0.018

z = -1.666

Now,

For P(X < 35%) = P(Z < -1.66)

= P(-∞ < Z < 0) - P(-1.66 < Z < 0)

= 0.5 - 0.4515 = 0.0485

Suppose you are hired by the STAR Lab to analyze vehicle arrivals at the right lane of the Evergreen Point Bridge on Westbound SR-520 for the period from 12:00am to 4:00am in a weekday. It is known that vehicle arrivals follow a Poisson process at this location and time period. There is a single-loop detector embedded on this lane at the east end of the bridge. Since you do not want to go to the bridge to count vehicles at this time period, you decided to use the loop detector data for the analysis. Of the 720 20-second intervals (the loop detection system stores data every 20 seconds), 508 intervals were identified to have at least one vehicle detected. Assume the loop detector is free of error. Please estimate the vehicle arrival rate (vehicles per second) for this lane. With the estimated arrival rate, please calculate the probability of having three or more vehicles detected in a 20-second interval and the probability of having a headway shorter than 10 seconds. [15 points]

Answers

Answer:

0.126

Step-by-step explanation:

Given :

Total time interval = 720

Number of interval in which one vehicle is detected =508

Proportion of atleast one detected vehicle :

508 / 720 = 0.7056

The mean arrival rate per second :

P(x ≥ 3) = 1 - P(x ≤ 3)

P(x ≥ 3) =1 - [p(x =0) + p(x = 1) + p(x =2) + p(x = 3)]

P(x ≥ 3) = 1 - 0.8745

P(x ≥ 3) = 0.1255

P(x ≥ 3) = 0.126

find the missing number in this proportion.

Answers

Step-by-step explanation: Remember that "times" mean multiply.

So reading the problem from left to right, we have n times 5,

that's n multiplied by 5 or 5n, is means equals, 24.

So we have 5n = 24.

We want to solve our equation for n so we want to get

n by itself on the left side of the equation.

Since n is being multiplied by 5, we need to divide both sides

of the equation by 5 and we have n = 24/5.

Answers

200 stamps

Step-by-step explanation:

Divide the 90 stamps by 45: The result is 2; it's equal to 1% of the total number of stamps. You then multiply it by 100 to get the full amount, which is 200 stamps.

90 stamps are .45 of her collection
90/.45=x/1.00
cross-multiply
.45x=90
x=200 stamps, dividing both sides by 0.45

+.45x+=+90+
+x+=+90%2F.45+

Answers

Answer:

x=9

Step-by-step explanation:

Original equation: 16x-8-14x=10

Combine like terms: 2x-8=10

Add 8 to both sides: 2x=18

Divide by 2 on both sides: x=9

Let me know if this helps!

Answer:

x=9

Step-by-step explanation:

16x-8-14x=10

16x+-8+-14x=10

(16x+-14x)+(-8)=10 ( Combine like terms)

2x-8=10

Add 8 to both sides

2x-8=10

+8 +8

2x=18

Divide both sides by 2

2x=18/2

x=9

Answers

Answer:

a = 1.8 to the nearest tenth.

Step-by-step explanation:

Remark

I don't think this case is ambiguous. It has only 1 solution, I think.

Step One

Find the top angle.

All triangles have 180 degrees.

15 + 105 + x = 180

120 + x = 180                     Subtract 120 from both sides

x = 180 - 120

x = 60

Step Two: Find a

a/sin(60) = 2/Sin(105)       Multiply both sides by sin(60)

a = 2 *  Sin(60) / sin(105)

a = 2 * .8660 / 0.9659

a = 1.793
