Solution Steps

To find the circumference of a circle, use the formula \( C = 2 \pi r \), where \( r \) is the radius of the circle. Substitute the given radius and the approximation for \(\pi\) into the formula to calculate the circumference.

Step 1: Identify the Formula for Circumference

The circumference \( C \) of a circle is calculated using the formula: \[ C = 2 \pi r \] where \( r \) is the radius of the circle.

Step 2: Substitute the Given Values

Given that the radius \( r = 4.6 \) miles and using the approximation \(\pi \approx 3.14\), substitute these values into the formula: \[ C = 2 \times 3.14 \times 4.6 \]

Step 3: Calculate the Circumference

Perform the multiplication: \[ C = 28.888 \]

Final Answer

The circumference of the circle is approximately \(\boxed{28.888}\) miles.

3. Find a cell that is in prophase. Prophase is characterized by the dark, spotty nucleus and the absence of nuclear envelope. Asters may also be seen. Draw one cell. - Why is the nucleus stained dark? The nucleus appears dark during prophase because the chromatin condenses into tightly packed chromosomes. - At this stage, each chromosome contains how many copies of DNA molecule? 4. Find a cell that is in metaphase. Metaphase is characterized by the arrangement of dark-stained chromosomes on metaphase plate. Draw one cell. - How many asters should one cell have? - Can you see spindle fibers? 5. Find a cell that is in anaphase. Anaphase is characterized by two somewhat parallel dark bands resulting from separation of sister chromatids. Draw one cell. - What attach to the centromere and pull daughter chromosomes to opposite poles?

A popular casino table game is three-card poker. One aspect of the game is the "pair plus" bet in which a player is paid a dollar amount for any hand of a pair or better, regardless of the hand the dealer has. The table available below shows the profit and probability of various hands of a player playing the 5 pair plus bet. Complete parts (a) and (b) below. (a) What is the expected profit when playing the 5 pair plus bet in three-card poker? The expected profit is - (Round to two decimal places as needed.) (b) If you play the game for 4 hours with an average of 35 hands per hour, how much would you expect to lose? Expect to lose (Round to two decimal places as needed.)
