Bot Darrell paints a circular logo that has a diameter of 15.5 inches. He wants to calculate the circumference, and he uses 3.14 as an estimate for *. His work is shown, but he makes an error. Step 1 (3.14)(15.5/2) Step 2 (3.14)(7.75) Step 3 24.335. Select the reason that Darrell's circumference calculation is incorrect, and enter the correct circumference using 3.14 for *. Pick one of these answers. Darrell applied the circumference formula incorrectly. Darrell multiplied 3.14 and 7.75 incorrectly. Darrell found the area instead of the circumference. The correct circumference, using 3.14 for *, is blank inches.
The correct circumference, using 3.14 for π, is 24.31 inches.
The reason Darrell's circumference calculation is incorrect is that he applied the circumference formula incorrectly. He multiplied 3.14 and 7.75 correctly in step 2, but he failed to perform the final multiplication correctly.

Jerrod's error first appears in Step 3. Jerrod's error first appears in Step 4. Jerrod's error first appears in Step 5. The correct value of 3/2 × |4 - ( -2)|³ + 1.5 is what?
Jerrod's error first appears in Step 1.
The correct value of 3/2 × |4 - (-2)|³ + 1.5 is 39.5.
Bot Elise has four cards labeled 1 to 4. She randomly draws a card, records the number, and puts it back in the deck. She repeats the process 99 more times. A table of her data is shown. Results: Number on Card:1 2 3 4 Frequency:10 40 26 24. Enter a value and select a phrase to compare the theoretical and experimental probabilities of drawing a card labeled 2. Based on Elise's data, the experimental probability of drawing a card labeled 2 is what? The experimental probability is less than, greater than, or equal to thr theoretical probability.
Based on Elise's data, the experimental probability of drawing a card labeled 2 is 40.
The experimental probability is greater than the theoretical probability.
Bot the table shows a proportional relationship. X:0 2 5. Y:b 4 c. What are the values of b and c?
To determine the values of b and c in the proportional relationship, we can use the given values of x and y.
The relationship between x and y is proportional, which means that the ratio between corresponding values of x and y will remain constant.
Using the given values:
When x = 0, y = b.
When x = 2, y = 4.
When x = 5, y = c.
To find the value of b, we can set up a proportion:
0/2 = b/4
Simplifying the proportion, we get:
0 = 2b/4
Cross-multiplying, we get:
0 = 2b
Therefore, b equals 0.
To find the value of c, we can set up another proportion:
2/4 = 5/c
Simplifying the proportion, we get:
2c = 20
Dividing both sides by 2, we get:
c = 10
So, the values of b and c are 0 and 10, respectively.
