Answer:
the scientific name is the same name around the world and if you use common names they are different around the world
Step-by-step explanation:
Answer:
8 hours
Step-by-step explanation:
Given:
Sheyna drives to the lake with average speed of 60 mph and
Sheyna drives back from the lake with average speed of 36 mph
It took 2 hours less time to get there than it did to get back.
Let 
be the time taken to drive to lake.
Let 
be the time taken to drive back from lake.
hrs ..... (1)
To find:
Total time taken = ?
Solution:
Let D be the distance to lake.
Formula for time is given as:
Putting in equation (1):
So,
So, the answer is:
Answer:
Step-by-step explanation:
1) Let the random time variable, X = 45min; mean, ∪ = 30min; standard deviation, α = 15min
By comparing P(0 ≤ Z ≤ 30)
P(Z ≤ X - ∪/α) = P(Z ≤ 45 - 30/15) = P( Z ≤ 1)
Using Table
P(0 ≤ Z ≤ 1) = 0.3413
P(Z > 1) = (0.5 - 0.3413) = 0.1537
∴ P(Z > 45) = 0.1537
2) By compering (0 ≤ Z ≤ 15) ( that is 4:15pm)
P(Z ≤ 15 - 30/15) = P(Z ≤ -1)
Using Table
P(-1 ≤ Z ≤ 0) = 0.3413
P(Z < 1) = (0.5 - 0.3413) = 0.1587
∴ P(Z < 15) = 0.1587
3) By comparing P(0 ≤ Z ≤ 60) (that is for 5:00pm)
P(Z ≤ 60 - 30/15) = P(Z ≤ 2)
Using Table
P(0 ≤ Z ≤ 1) = 0.4772
P(Z > 1) = (0.5 - 0.4772) = 0.0228
∴ P(Z > 60) = 0.0228
I don’t feel like doing school and I keep getting distracted by this app
The correct answer is D. 2s + 3
Hope this helps!
