a. How many selected traveling as their favorite hobby?

Answers

Answer:

180 people

Step-by-step explanation:

Total of people surveyed = 1,000

% of people that selected travelling as their favorite hobby = 18 %

Number of people that selected travelling = % that selected travelling of 1,000

= 18% of 1,000

= 18/100 × 1,000

= 180 people

Therefore, 180 people selected travelling as their favorite hobby.

1. A company has $6582 to give out in bonuses. An amount is to be given out equally to each of the 32 employees.
(a) A manager, Jake, reasoned that since 32 goes into 64 twice, each employee will get about $2000. Is his estimate correct? Why or why not?
(b) How much will each employee receive, rounded to the nearest whole dollar? Leave the remainder undivided. Show your work.
Answer:

Answers

Answer:

A) His estimate is incorrect, since he has increased a figure to the amount that each employee would receive.

B) Rounded to the nearest dollar, each employee would receive $ 209.

Step-by-step explanation:

Since a company has $ 6582 to give out in bonuses, and an amount is to be given out equally to each of the 32 employees, and A) a manager, Jake reasoned that since 32 goes into 64 twice, each employee will get about $ 2000 , to determine if his estimate is correct, and B) determine how much will each employee receive, rounded to the nearest whole dollar, the following calculations must be performed:

A)

2000 x 32 = 64000

200 x 32 = 6400

Therefore, his estimate is incorrect, since he has increased a figure to the amount that each employee would receive.

B)

6582/32 = X

208.68 = X

Therefore, rounded to the nearest dollar, each employee would receive $ 209.

Answer:

Equation = 4x + 9y = 16

Step-by-step explanation:

co-ordinate = (-5.4) & (4,0)

slope(m) = (0-4) / (4+5)

slope(m) = -4 / 9

For a sample with mean = 50 and standard deviation = 10...
A. Find the z-score for each of the following X values:
X = 60
X = 75
X = 30

Answers

X = 60 is 1 standard deviation above the mean.

X = 75 is 2.5 standard deviations above the mean.

X = 30 is 2 standard deviations below the mean.

To find the z-score for a particular X value, we use the formula:

z = (X - mean)/standard deviation

where X is the given value, mean is the population mean, and standard deviation is the population standard deviation.

For X = 60:

z = (60 - 50)/10 = 1

Therefore, the z-score for X = 60 is 1.

For X = 75:

z = (75 - 50)/10 = 2.5

Therefore, the z-score for X = 75 is 2.5.

For X = 30:

z = (30 - 50)/10 = -2

Therefore, the z-score for X = 30 is -2.

The z-score represents the number of standard deviations that a particular X value is away from the mean. Since the mean z-score is 0 and a positive z-score means that the X value is above the average.

Find the area of the smaller sector.
Round to the nearest tenth.

Area = [? ]ft2

Answers

Answer:

22.2

Step-by-step explanation:

Hello There!

This is the sector area formula

[tex]A=\frac{0}{360} (\pi r^2)[/tex]

where 0 = sector angle

and r = radius

The given sector has a measure of 50 degrees and a radius of 7.13

Knowing this information we plug it into the formula

[tex]A=\frac{50}{360} (\pi 7.13^2)\\\frac{50}{360} =0.1388888889\\7.13^2=50.8369\\50.8369\pi =159.7088316\\159.7088316*0.1388888889=22.18178216[/tex]

so we can conclude that the area of the sector is 22.18178216 ft²

finally we round to the nearest tenth

and get that the answer is 22.2

[? ]%
Round to the nearest tenth of a percent.

Answers

Answer:

25.54

Step-by-step explanation:

somebody say it on the comments :)

The probability that a randomly selected point within the circle falls in the red-shaded area is 75.61%.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

We need to find the probability that a randomly selected point within the circle falls in the white area.

We have been given the following parameters;

Radius r = 4 cm

a = 3.2 cm

S = 4.7 cm

The area of the circle A = πr²

A = π(4)²

A = 16π square cm

Here, The total number of outcomes = 16π square cm = 50.26 square cm

The side length of the pentagon a = 4.7 cm

The area of the pentagon can be calculated using:

Area = (1/4)√[5(5+2√5)]a²

Plug a = 4.7

Area = (1/4)√[5(5+2√5)](4.7)²

After calculating, we get;

Area = 38.01 square cm

The Total favorable outcomes = 38.01 square cm

The probability = 38.01/50.26

The probability = 0.7561

In percent,

The probability = 75.61%

Therefore, the probability that a randomly selected point within the circle falls in the red-shaded area is 75.61%.

In this problem you will derive the efficiency of a CSMA/CD like multiple access protocol. In this protocol the time is slotted and all nodes are synchronised to the slot times. The length of a slot in this case is much less the than the actual time to transmit one frame. Let the slot length be S seconds Let the frame length be L bits Let the transmission rate be R bps Let the number of nodes be N and assume that each node has an infinite amount of packets to send Assume the propagation delay is much less than S, so that all nodes can detect a collision before the end of the slot. The protocol operates as below: o Ifa node has not acquired the channel, all nodes contend with probability p. If exactly 1 user transmit in that slot, then that user keep possession of the channel for the next k slots, transmitting an entire frame. o If a node has the possession of the channel, other nodes refrain from transmitting until that node finish transmitting the frame. Once the transmission completes all nodes again compete for the channel. Avery leans a 24-foot ladder against a wall so that it forms an angle of 80 with the ground.
