Hello!
We have to find how fast the car goes a minute
To find this we can do 57/60 since the car goes 57 miles an hour and there are 60 minutes in an hour
This gives us 0.95 miles a minutes
Answer:
Probability of an event E = p(E) = (number of favorable outcomes of E)/(number of total outcomes in the sample space) This approach is also called theoretical probability. The example of finding the probability of a sum of seven when two dice are tossed is an example of the classical approach.

Answer:
Mean speed is 55.7 mph.
Step-by-step explanation:
The provided frequency distribution is:
Speed Cars
30-39 4
40-49 19
50-59 50
60-69 15
70-79 12
The formula to compute the mean for the grouped data is:
Here, m is mid point and f is frequency.
The mean speed can be computed as:
Thus, the mean speed is 55.7 mph.
Answer:
L= 42
M= 88
N= 50
X= 42
Y= 88
Z= 50
Step-by-step explanation:
X and L have congruent angles
M and Y have congruent angles as well
Then to find X and L do 180-50 and subtract 88 as well.
