A package of ground beef costs $6.98. The price per pound is $3.86. How many pounds of ground beefare in the package? Round to the nearest hundredth.
A. .27
B. 1.81
C. 1.80
D. 1.72

Answers

Answer 1

Answer: We have to find how many pounds of ground beef are in the package and to round that number to the nearest hundredth. We know that a package costs $6.98 and that the price per pound is $3.86. We will divide the cost of a package by the price per pound. 6.98 : 3.86 = 1.80829. When we round it to the nearest hundredth it is 1.81. Answer: B ) 1.81.

Answer 2

Answer:

Answer:

B. 1.81 pounds.

Step-by-step explanation:

We have been a package of ground beef costs $6.98. The price per pound is $3.86.

To find the number of pounds of ground beef in the package we will divide the cost of package by cost of each pound of ground beef.

$\text{The number of pounds of ground beef in the package}=(\$6.98)/(\$3.86)$

$\text{The number of pounds of ground beef in the package}=1.808290155$

Upon rounding our answer to nearest hundredth we will get,

$\text{The number of pounds of ground beef in the package}\approx 1.81$

Therefore, there were 1.81 pounds of ground beef in the package and option B is the correct choice.

Sarah described the following situation:When fertilizer was added to one plant and nothing was added to another plant, there was a noticeable difference in the color of the leaves of the plants.

Which of the following best describes the situation?

A. This is an example of correlation but not causation.

B. This is an example of causation but not correlation.

C. This is an example of both correlation and causation.

D. This is an example of neither correlation nor causation.

Answers

When Sarah added the fertilizer and there was a noticeable difference, we can say that:

B. This is an example of causation but not correlation.

What is Causation?

Causation occurs when an effect is noticed because of a traceable item. The traceable item, in this case, is the fertilizer.

So when the fertilizer was added and a change in color was noticed, we can deduce that the difference was because of the fertilizer.

Therefore, option B is correct.

Answer: B.) This is an example of causation but not correlation.

Step-by-step explanation: Causation is a cause and effect, because fertilizer was added to one plant, it's leaf color was improved.

A, B & C form a triangle where ∠ BAC = 90°. AB = 13.5 mm and CA = 3.2 mm. Find the length of BC, giving your answer rounded to 1 DP.

Answers

Answer:

13.9

Step-by-step explanation:

Use Pythagorean Theorem:

Both of the lengths given are the legs,

13.5^2 + 3.2^2 = c^2

182.25 + 10.24 = c^2

192.49 = c^2

13.87 = c

What is 782,444 rounded to the nearest hundred thousand

Answers

782,444 rounded to the nearest hundred thousand would be 800,000.

This is because we know that the hundred thousands place has a 7 in it, so it would be 700,000. However, because 8 is greater than 5, we have to round up instead of down.

Hope this helps!

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.
