Which measurement is most accurate to describe the weight of a quarter?630 g
63 mg
6.3 g
0.63 kg

Answers

Answer 1
Answer:

Answer: 6.3 g

Step-by-step explanation:

First, we need to put every mesure into the same unit. Let's put all into grams.

- kg would be too heavy for a quarter (consider that we use kg to weight people, for example)

- mg is too light (consider that we use mg to weight pills, for example)

We know that

1 kg = 1000 g

1 g = 1000 mg

630 g = 630 g

63 mg  = 63/1000 = 0.063 g

6.3 g  = 6.3 g

0.63 kg = 0.63*1000 = 630 g

The most suitable answer for a quarter is 6.3g, because 630 g would be too heavy and 0.063 g would be too light.
Answer 2
Answer: 63 mg it is the smallest measurement listed.

Answers

Note: Since you missed to add the image, so after a little research, I was able to find the image related to this question, which hopefully serves the purpose to clear your concept. The image is attached below.

Step-by-step explanation:

Part 1) What is the slope for section "d" of Mrs. Washington's commute

Calculating the slope for section "d" of Mrs. Washington's commute:

Slope of the section d  =(y_(2) - y_(1))/(x_(2) - x_(1))

(6 - 0)/(32 - 20)=(1)/(2)=0.5

Part 2) What does it mean that the slope is negative in context of the problem?

The slope is being negative as it is moving downward from the left. In negative slop, the value of x increase, while the vale of y decreases. In positive slop, the value of both x and y increases.

Part 3) Why are the slopes different over different intervals?

Slopes are different at different intervals as the distance covered in time taken for each part of the given journey are different, also the speed is not the same for each interval.

As the speed can be calculated as

Speed\:=\:(distance)/(time)\:

Distance = y_(2) -y_(1) = 20 - 15 = 5

Time = x_(2) -x_(1)= 8 - 0 = 8

Speed = (5)/(8)=0.625

Therefore, the speed in the part 1 is 0.625ms^(-1)

Part 4) How long does it take Mrs. Washington to get home? How did you know this?

It is clear from the graph that does take 32 minutes to her to get home.  

We can observe it from the graph that it represents the total time taken across the entire journey.

A paper drinking cup in the shape of a cone has a heightof 10 centimeters and a diameter of 8 centimeters.

Which of the following is closest to the volume
of the cup in cubic centimeters?

27 cm
53 cm
80 cm
160 cm

Answers

The solution is, 160 cm is closest to the volume of the cup in cubic centimeters.

What is volume of cone ?

The formula for the volume of a cone is ⅓ r2h cubic units, where r is the radius of the circular base and h is the height of the cone.

here, we have,

a cone has a height of 10 centimeters

and a diameter of 8 centimeters.

so, we know,

Volume =  ⅓ r²h

i.e. V = 167.55

Hence, 160 cm is closest to the volume of the cup in cubic centimeters.

Answer:

I am pretty sure it is 53cm.

Step-by-step explanation:

If it were in a cylinder shape 10 x 8 is 80 but is is in the shape of a cone so the volume lessens so it can't be 80cm or 160cm. 27cm is a bit to low so that is why I am 90% sure it is 53cm.

Donner Summit, California, is a popular ski resort area. Over the past 60 years, the annual snowfall totals of Donner Summit have followed a distribution that is strongly skewed right with a mean of 404 inches and a standard deviation of 129 inches. If many samples of size 9 were taken, which of the following would best describe the shape of the sampling distribution of xbar

Answers

Answer:

This sampling distribution will only reflect the nature of its population distribution (strongly skewed right because the sample size of each sample, 9, is way less than the sample size of 30 required for the sampling distribution to be approximately normal) with mean 404 inches and standarddeviation of sampling distribution equal to 43 inches.

Step-by-step explanation:

The Central limit theorem explains that for an independent, any random set of sample taken from such a population distribution will have a distribution that is approximately normal (provided that the sample size is large enough) with the mean of sampling distribution also approximately equal to the population mean and the standard deviation of the sampling distribution is given as

σₓ = (σ/√n)

where

σ = population standard deviation

n = sample size

To work these out,

Mean of sampling distribution = population mean

μₓ = μ = 404 inches

Standard deviation of the sampling distribution = σₓ = (σ/√n)

σ = population standard deviation = 129 inches

n = sample size = 9

σₓ = (129/√9) = 43 inches.

For most databases, the 'large enough' criteria for the sampling distribution to be approximately normal is a sample size of about 30 and it gets closer as the sample size becomes larger.

The sample size in the question is 9 which is way less than 30, hence, this sampling distribution will only reflect the nature of its population distribution (strongly skewed right) with mean 404 inches and standarddeviation of sampling distribution equal to 43 inches.

Hope this Helps!!!

Answer:answer is D The shape is skewed right but less so than the population distribution.
