Solution Steps

To find the approximate number of e-scooter rides that resulted in injuries, we need to calculate the injury rate for each given scenario and then sum them up. The injury rate is calculated by dividing the number of injuries by the total number of rides and then multiplying by the total number of rides to get the number of injuries.

Step 1: Calculate Total Injuries

We are given the following data for e-scooter rides resulting in injuries:

  • \( \text{Injuries}_1 = 10 \) out of \( \text{Rides}_1 = 500,000 \)
  • \( \text{Injuries}_2 = 40 \) out of \( \text{Rides}_2 = 750,000 \)
  • \( \text{Injuries}_3 = 20 \) out of \( \text{Rides}_3 = 100,000 \)
  • \( \text{Injuries}_4 = 30 \) out of \( \text{Rides}_4 = 250,000 \)

To find the total number of injuries, we sum the injuries from each scenario:

\[ \text{Total Injuries} = \text{Injuries}_1 + \text{Injuries}_2 + \text{Injuries}_3 + \text{Injuries}_4 = 10 + 40 + 20 + 30 = 100 \]

Final Answer

The total number of e-scooter rides that resulted in injuries is \\(\boxed{100}\\).

- You were first asked to elicit a second stimulus after the force of the muscle completely fell. The second stimulus should have resulted in a stronger second contraction. What phenomenon was demonstrated and what generally causes that phenomenon? -When asked to elicited multiple stimuli before the muscle completely relaxed, what kind of summation were you simulating? - When you were asked to "mash" the stimulus button, what phenomenon were you trying to simulate?

Read the stanza from "Monet's 'Waterlilies"' by Robert Hayden. How does the imagery in the stanza contribute to the poem's overall meaning? O light beheld as through refracting tears. Here is the aura of that world Here is the shadow of its joy. It illustrates tears as being soothing. It illustrates a sense of misfortune. It illustrates faith in humankind. It illustrates the beauty of nature.
