Answer:
D
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Here r = 15, thus
x² + y² = 15² , that is
x² + y² = 225 → D
Answer:
Please see the answers below:
Step-by-step explanation:
The wrong answers are deleted only the correct answers are listed below:
- Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.
- Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.
- Claire saves $320 in 16 weeks. The unit rate is $20 per week.
- % increase in price of gas = [(New Price - Original Price) / Original Price] x 100
% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100
% increase in price of gas = [$0.3 / $2.18] x 100
% increase in price of gas = 13.76%
Don't know if it's right, but do let me know! use percentage to visualise your workings. :)
The number of simple events in this experiment according to the probability is 16.
According to the statement
we have to find that the number of simple events in this experiment.
So, For this purpose, we know that the
Simple events are the events where one experiment happens at a time and it will be having a single outcome. The probability of simple events is denoted by P(E) where E is the event.
And according to the given information is:
Total number of coins tossed is 4.
then
the simple events become
Simple events = no. of coins * total coins tossed
Simple events = 4*4
Now solve it then
Simple events = 16.
So, The number of simple events in this experiment according to the probability is 16.
