Which event has theoretical probability of exactly One-fifth? Select three options.

Answers

Answer:

1.) spinning a 4 or 5

2.) spinning a number less than 3

3.) spinning a number greater than 8

Step-by-step explanation:

The spinner has 10 spaces, if we took a 4/5 (2) and made it into a fraction (2/10) then simplified is (1/50---Less than 3, so that means not 3 itself either, so a 1 or a 2, so (2/10), then simplify it, (1/5)--- Greater than 8, so not 8 itself, so 9 or a 10 (2/10) then simplified, (1/5)

Answer:

A) solution 2 is more acidic than solution 1

Step-by-step explanation:

A chemist prepares two acid solutions:

Solution 1: 3 parts sulfuric acid to 7 parts water

Ratio of sulphur to water: 3/7 (3:7)

Solution 2: 4 parts sulfuric acid to 9 parts water

Ratio of sulphur to water: 4/9 (4:9)

___________________________________________________

Part A: (using ratios to determine which solution is more acidic)

First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.

Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63

Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63

Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.

Mathematical Line (Not sure what you would call this lol): 28 > 27

Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)

Equation of solution 1: y = 3/7x

Equation of solution 2: y = 4/9x

Please find attachment for graph.

Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)

Use a number line to order the numbers from least to greatest.

Answers

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

9/4=2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

A metal paperweight is in the shape of a cylinder. The paperweight has the height of 1.5 inches and a diameter of 2 inches. How much does the paperweight weigh if 1 cubic inch weighs 1.8 ounces? Round to the nearest tenth!

Answers

Answer:

8.5 ounces

Step-by-step explanation:

area of circle = pi*r^2

pi*1^2 = pi

pi*1.5 = 8.48 = 8.5

The weight of the paperweight is 8.5 ounces.

Concept:Firstly, we will calculate the volume of the cylinder by using the formula,
$V = \pi r^2h$Then, we will find the weight by multiplying volume with a specific weight.

How to solve the given question?For the given paperweight,
Diameter = 2 inches ⇒ Radius = 1 inchVolume of Cylinder, $V = \pi r^2h$
∴ $V = \pi (1)^2 (1.5) = 4.72 \ inch^3$As the weight of 1 cubic inch = 1.8 ounces
∴ Weight, W = 4.72 × 1.8 = 8.5 ounces

The weight of the paperweight is 8.5 ounces.

In a pile of playing cards, there are six hearts, twelve clubs, and six diamonds. What is the probability that you will draw a heart?
1/2
1/6
1/4
1/3

Answers

Answer:

Step-by-step explanation:

1/4 because all equal 24 together

and so

12 is half so pulling a club would be 1/2

6 is a fourth so pulling a diamond or heart would be 1/4

because 6x2=12 so pulling a diamond or heart would be 50 - 50 from pulling a heart/diamond or a club

6=cards

2=diamonds and hearts

The probability of drawing a heart from the pile of 52 cards is 0.25.

The ratio of the number of favorable outcomes to the total number of outcomes of an event is defined as probability.

We know, the probability of an event = Number of favorable outcomes/Total number of outcomes.

As it is given that there are 6 hearts, 12 clubs, and 6 diamonds in a pile of playing cards.

Therefore, the total number of outcomes = 6+12+6= 24

and number of favorable outcomes = 6

Now, the probability of an event = 6/24

= 1/4

= 0.25

Therefore, the probability of drawing a heart is 0.25.

========================================================

Explanation:

We have these three rules for scale factors

scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identical

With those rules in mind, we have enlargements for these transformations.

P to QP to RQ to R

All of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

----------------

We also have these reductions

Q to SR to P

This is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

----------------

And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.

P to SS to P

The order doesn't matter for this subset, but the order will matter for the other batches of transformations.

American Trucking Associations, Inc.,BackgroundSection 109(b)(1) of the Clean Air Act instructed the EPA to set "ambient air quality standards the attainment and maintenance of which in the judgment of the Administrator, based on [the] criteria [documents of Section 108] and allowing an adequate margin of safety, are requisite to protect the public health." The D.C. Circuit Court of Appeals had decided that the standard making procedure delegated by Congress to the EPA to set air quality was an unconstitutional delegation in contravention of Article I, Section I, of the US Constitution because the EPA had interpreted the statute to provide "no intelligible principle" to guide the agency's exercise of authority. It also found that the EPA could not consider the economic cost of implementing a national ambient air quality standard.DecisionIn an opinion written by Justice Antonin Scalia, the Supreme Court affirmed in part and reversed in part the Court of Appeals' decision.[3] The Court affirmed that the text of Section 109(b) unambiguously barred cost considerations from the NAAQS-setting process. The Court wrote, "Whether the statute delegates legislative power is a question for the courts, and an agencys voluntary self-denial has no bearing upon the answer."[4] The Court determined that the scope of discretion that Section 109(b)(1) allowed was well within the outer limits of nondelegation precedents.[5] The Court concluded this based on prior holdings, noting it had only twice found an intelligible principle lacking in a statutory delegation: one which contained "literally no guidance for the exercise of discretion," and the other "conferred authority to regulate the entire economy on the basis of no more precise a standard than stimulating the economy by assuring 'fair competition.'"[6] Consequently, the Court remanded the case for the Court of Appeals to reinterpret the statute that would avoid a delegation of legislative power.[7]ConcurrenceJustice Clarence Thomas wrote a separate concurrence. He was not sure that the intelligible principle criterion served to prevent all cessions of legislative power.[8] He believed that there are cases in which the principle itself is intelligible but the significance of the delegated decision is simply too great for the decision to be called anything other than legislative. He stated that he would be willing to reconsider the delegation precedents in the future to determine whether delegation jurisprudence has strayed too far from Founders' understanding of separation of powers. The Court also held that EPAs implementation policy constituted a final agency action subject to judicial review and that two statutory provisions for ozone, Subpart I and Subpart 2, were seemingly in conflict and EPA must reconcile these provisions on remand.[9]Justice John Paul Stevens also wrote a separate concurrence, which was joined by Justice Souter.[10]Questions:In your own words, what do you think the Supreme Court said regarding the consideration of the costs of implementation?Do you think the Supreme Court was correct in its interpretation of the CAA as it relates to greenhouse gas emissions?
