Answer:

The answer is 20 points

Step-by-step explanation:

If the points is based on 100 by rating, and your confidence level of 'I think I know it' places you on the initial risk of 80 points as suggested, which eventually places you on the wrong side, you will be left with the following:

Total rating point of 100 minus initial risking points of 80. This leaves you with a second chance points of just 20.

(MATH) (6) ((PHOTO))<br>label is sq yd​
Annette [7]

Answer:

<em>20 sq yd</em>

Step-by-step explanation:

To find the total amount of sq yd's of paint needed, you have to find the area.

The area of a triangle is: A = 1/2 bh

We know:

b = base = 8

h = height = 5

Plug in and solve:

A = 1/2 (8) (5)

A = 1/2 (40)

A = 20

Kurt and Maria's high school is having a newspaper drive.The goal is to collect 3,585 pounds of newspapers. So far, 21% of the g
Novay_Z [31]

Options:

Who is right, and why?

a. Neither Kurt nor Maria is right, because 3,500 should be used instead of 3,600.

b. Kurt is right, because finding 1/5 of 3,600 is not a good way to approximate 21% of 3,585.

c. Maria is right, because finding 10% of 3,600 and multiplying the result by 2 is not a good way to approximate 21% of 3,585.

d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.

Answer:

d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.

Step-by-step explanation:

Given

Goal = 3585

Collected = 21\%

Kurt= 10\% * 3600 * 2

Maria = \frac{1}{5} * 3600

Required [Missing from the question]

Who is correct and why?

First, we calculate the actual amount collected.

Actual = Collected * Goal

Actual = 21\% * 3585

Actual = 752.85

Actual = 753 --- approximate

Next, determine the estimate (round 3585 to 3600 and 21% to 20%)

Estimate = 20\% * 3600

Estimate = 720

Next, calculate Kurt and Maria's estimates

Kurt= 10\% * 3600 * 2

Kurt = 720

Maria = \frac{1}{5} * 3600

Maria = 720

<em>Hence, Kurt and Maria are correct because of option (d)</em>

When you are finished with the experiment, complete the following data analysis and submit your answers.

Determine the volume of the box and the block.

Determine the ratio of the block to the box:

The volume of box=(L)(W)(H)

The volume of the block (L)(W)(H)

Multiply this number by 100 to turn it into a percent.

Complete this statement: The volume of the block is _____ percent of the volume of the box.

Determine the ratio of the number of hits to the number of shots:

(number of hits100 shots)

Multiply this number by 100 to turn it into a percent.

Complete this statement: The block was hit _____ percent of the time.

Compare the results of step 2 to the results of step 3. Are the percentages similar?

Write a conclusion discussing the following items:

Based on your findings, do you think Rutherford's hypothesis was reasonable?

Restate Rutherford's hypothesis and describe how you tested it.

State whether your results support the hypothesis. If they do not, can you suggest some error in experimental procedure (other than a general human error) that might explain it?

Finally, explain how this experiment confirms the nuclear model of the atom and the idea that most of the atom is empty space.
