For which swimming stroke is diving not recommended to start a race?

Answers

Answer:

Backstroke

Explanation:

For backstroke, you have to lay on your back. When I was on a swimming team, we'd always go on the diving blocks for all strokes except for backstroke.

Backstroke is the swimming stroke in diving that is not recommended to start a race

There are different types of swimming strokes such as

Butterfly Backstroke BreaststrokeFreestyle

The backstroke involves the use of the back on water for movement. This

stroke has a main advantage which is the ability of the swimmer to  breathe

well in water as his nose aren't always submerged in it.

The backstroke isn't however recommended to start a race as there is the

issue of the inability to see where he/she has to dive into the water or swim

through. Other swimming strokes are however recommended for starting a race.

The base model, Reguplo, has demand that is normally distributed, with a mean of 10,000 and a stand deviation of 1,000. The three other models have additional features, and each has demand that is normally distributed, with a mean of 1,000 and a standard deviation of 700. Currently all four models are manufactured on the same line at a cost of $100 for Reguplo and $110 for each of the other three models. Reguplo sells for $200, whereas each of the other three models sells for $220. Any unsold blowers are sold at the end of the season for $80. Snoblo is considering the use of tailored sourcing by setting up two separate lines, one for Reguplo and one for the other three. Given that no changeovers will be required on the Reguplo line, the production cost of Reguplo is expected to decline to $90. The production cost of the other three products, however, will now increase to $120.Required:a. How will tailored sourcing affect the production and profits? b.
