mary pulls out a bead from a bag containing white, red, and yellow beads. she records the color and places it back into the bag. the table below shows the frequency of each color after 100 beads are pulled out. color of beads white red yellow number of draws 27 35 38 how many white draws can you expect if the beads are pulled out 1,000 times? 270 350 390 926

Answers

Answer 1

Answer: P(white) = 27/100 = 270/1000

Therefore, in 1,000 pulls, we eaxpect 270 white beads,

Answer 2

Answer:

A number is multiplied by 7. Then 29 is added to the product. This sum is then divided by 2. The answer is 46. What was the original number? Student's solution - The answer was 46. If this was the result of dividing by 2, the number at this point was 92. If this was the result of adding 29, the number at this point was 63. If this was the result of multiplying by 7, the original number was 9.

Solve this problem using a similar strategy.

A number is multiplied by 10. Then 32 is added to the product. This sum is then divided by 4. The answer is 28.

What was the original number?

Answers

For the student's solution, the student started with the final answer and then worked backwards.
Start your solution with
The answer was 28.

Working backwards, the sentence in the question after the answer is "This sum is then divided by 4."
Use the same thing as the student's solution, but switch out the different numbers.
If this was the result of dividing by 4, the number at this point was 112. ( $28*4=112$ )
The next sentence in the question then says "Then 32 is added to the product."
Going off of the student's solution,
If this was the result of adding 32, the number at this point was 80. ( $112-32=80$ )
Again looking at the question, "A number is multiplied by 10."
Going off of the student's solution,
If this was the result of multiplying by 10, the original number was 8. ( $(80)/(10)$ )

The answer is 8.

Step-by-step explanation:

The bottom of a box has a surface area of 31.4 cm2. The mass of the box is 47.1 kilograms. Acceleration due to gravity at sea level is 9.80 m/s2. What pressure is exerted by the box where it rests?14.7 N
1.5 N
0.153 N
6.53 N

Answers

The correct answer to the physics problem in pressure given above would be 1.5 N.

First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).

Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)

Consequently, I used the equation of pressure (P = Force/Area).
P = 461.58 N / .00314 m^2
P = 1.47 or 1.5 N

Answer:

Pressure = 147,000 N.

Step-by-step explanation:

Given : The bottom of a box has a surface area of 31.4 cm². The mass of the box is 47.1 kilograms. Acceleration due to gravity at sea level is 9.80 m/s².

To find : What pressure is exerted by the box where it rests.

Solution : We have given that area of box = 31.4 cm²

First we convert it in meter².

1 meter = 100 cm

31.4 cm² = 0.00314 meter².

Mass of box = 47.1 kg

Acceleration due to gravity = 9.80 m/s².

According to Newton second law of motion , F = mass * Acceleration due to gravity.

F = 47.1 * 9.8

F = 461.58 Newton.

Pressure = $(Force)/(Area)$ .
