Lucy has the spinner pictured and
spins it twice in a row. What is the
probability that she lands on blue
first and then on yellow or green?
Answers
Answer:
d
Step-by-step explanation:
Final answer:
To find the probability of landing on blue first and then on yellow or green, one must multiply the probability of landing on blue by the combined probability of landing on yellow or green. However, exact probabilities cannot be provided without more information about the spinner.
Explanation:
The student is asking about the probability of a sequence of events occurring with a spinner. To calculate the probability of landing on blue first and then on yellow or green on the second spin, we must first know the individual probabilities of landing on each color. Assuming the spinner is fair and has equal sections for each color, the probability of landing on blue on the first spin (P(B)) and the probability of landing on yellow (P(Y)) or green (P(G)) on the second spin need to be calculated separately.
The probability of two independent events occurring in sequence is the product of their individual probabilities. Therefore, if the probability of landing on blue first is P(B), and the combined probability of landing on either yellow or green on the second spin is P(Y or G), then the total probability of the sequence is P(B) multiplied by P(Y or G). However, without the exact probabilities or a clear description of the spinner, we cannot provide a numerical answer.

6. A cone has a diameter of 6 inches and a height of 8 inches. Find the
volume using 3.14 for Tr. *
Answers
Final answer:
To calculate the volume of a cone with a diameter of 6 inches and a height of 8 inches, use the radius which is 3 inches and apply the formula V = 1/3πr²h, resulting in a volume of 226.08 cubic inches.
Explanation:
The subject's question is about finding the volume of a cone with a given diameter and height. The formula to calculate the volume of a cone is V = ⅓πr²h. Given that the diameter is 6 inches, the radius (r) is half of that, which is 3 inches. Using 3.14 for π (pi), and the given height (h) of 8 inches, we can substitute these values into the formula to find the volume.
So, the calculation is:
Find the radius (r) by dividing the diameter by 2, r = 3 inches.
Substitute r and h into the volume formula: V = ⅓πr²h = ⅓(3.14)(3 inches)²(8 inches).
Calculate the square of the radius (3 inches)² = 9 inches².
Multiply the area with height and π: V = ⅓(3.14)(9 inches²)(8 inches) = 226.08 cubic inches.
Therefore, the volume of the cone is 226.08 cubic inches.

During his career, Walter Payton rushed for 16,726 yards. How many feet is that? I WILL GIVE BRAINLIEST!!!!!!!!
Answers
Step-by-step explanation:
1 yard = 3 feet so we will multiply 16726 yards with 3 so answer = 16726 × 3 = 50178
Final answer:
To convert yards to feet, multiply the number of yards by 3. Walter Payton rushed for 16,726 yards, which equals 50,178 feet when converted.
Explanation:
The question asks to convert the number of yards rushed by Walter Payton during his career into feet. To find the conversion, you can use the fact that there are 3 feet in 1 yard. Therefore, to convert yards to feet, you should multiply the number of yards by 3.
Walter Payton rushed for 16,726 yards during his career. Using the conversion factor:
Feet = Yards × 3So,
Feet = 16,726 yards × 3
Feet = 50,178 feet
Thus, Walter Payton rushed for 50,178 feet during his career.

Martin made his first mistake in Step 2.
Explanation:Martin made his first mistake in Step 2.
In Step 2, Martin subtracted 25 from both 1,000 and 200, correctly. However, for the third number, 50 / 25 is actually 2, not 25. Therefore, the correct calculation should be (50 / 25) instead of (50 - 25).
So, the correct calculation in Step 2 should be (1,000 - 25) + (200 - 25) + (50 / 25) = 975 + 175 + 2 = 1,152.

A rectangle has a height of 5 and a width of 4x2 – 2x – 6.
Express the area of the entire rectangle
Expression should be expanded.
Answers
Answer:
The area of the rectangle is given by the expression "20x² - 10x - 30".
Step-by-step explanation:
The area of a rectangle is given by the product of it's dimensions. This is shown in the formula bellow:
area = width*height
In this case the width is an expression, so we need to multiply the numeric part of each mnemonic
area = 5*(4x² - 2x - 6)
area = 20x² - 10x - 30
The area of the rectangle is given by the expression "20x² - 10x - 30".
