Answer: It will take the Dolphin 2 hours to swim 40 miles. The penguin will take 8 hours. The swordfish will take 2/3 of an hour, that is 40 minutes, to travel 40 miles.

Step-by-step explanation: Divide the given distance by the unit rate given:

40/20=2 hours

40/5=8 hours

40÷60= 2/3 hour

This is the reverse of the process described in the question.

If the dolphin takes 2 hours to swim 40 miles, what is its unit rate? x ÷ y = R 40 miles÷2 hours= 20 mph.

40 miles ÷ 2/3 hour

3/2 × 40 = 60 mph

I hope this helps.

Add an intersection the red light times normally distributed by the mean of three minutes and a standard deviation of .25 minute
Soloha48 [4]

95% of red lights last between 2.5 and 3.5 minutes.

<u>Step-by-step explanation:</u>

In this case,

  • The mean M is 3 and
  • The standard deviation SD is given as 0.25

Assume the bell shaped graph of normal distribution,

The center of the graph is mean which is 3 minutes.

We move one space to the right side of mean ⇒ M + SD

⇒ 3+0.25 = 3.25 minutes.

Again we move one more space to the right of mean ⇒ M + 2SD

⇒ 3 + (0.25×2) = 3.5 minutes.

Similarly,

Move one space to the left side of mean ⇒ M - SD

⇒ 3-0.25 = 2.75 minutes.

Again we move one more space to the left of mean ⇒ M - 2SD

⇒ 3 - (0.25×2) =2.5 minutes.

The questions asks to approximately what percent of red lights last between 2.5 and 3.5 minutes.

Notice 2.5 and 3.5 fall within 2 standard deviations, and that 95% of the data is within 2 standard deviations. (Refer to bell-shaped graph)

Therefore, the percent of  red lights that last between 2.5 and 3.5 minutes is 95%

Which inequality defines the shaded region graphed below?
masha68 [24]

Answer:

Every ordered pair within this region will satisfy the inequality y ≥ x. Incorrect. The boundary line here is y = x, and the correct region is shaded, but remember that a dotted line is used for < and >. The inequality you are graphing is y ≥ x, so the boundary line should be solid.
