Answer:
2. 1- Experimental probability of rolling a 4 = 40%
3. 2- Theoretical probability is 3% greater than experimental probability.
Step-by-step explanation:
Experimental probability of rolling a 4 = 100 × 
= 100 × 0.4
= 40%
Experimental probability of getting at least one tail = 
= 0.72
Theoretical probability of getting at least one tail = 
= 0.75
Theoretical probability is 3% greater than experimental probability.
Answer:
9
Step-by-step explanation:
PEMDAS IS
parentheses
Exponents
Multiply and divide
Addition and subtraction
First you start with the parentheses so
1 + 2 = 3
Now you have 6/2 x 3
Multiply and divide means you either divide or multiply what ever comes first going left to right
So
6/2 = 3
3 x 3 = 9
If it was reversed we’d have
2 x 3/6 which would be
6/6 = 1
Answer:
.
Step-by-step explanation:
The given equation is

Using distributive property, we get



Isolate variable terms.


Divide both sides by -0.35.



Therefore,
.
Answer:
Step-by-step explanation:
a) Standard deviation of 10 mean the fluctuation for values range from +10 to -10 from the mean.
b) Since the sixth student is 50 minutes, which is higher than the mean of 45 minutes, this will bring the over all mean higher that 45 minutes. Also, since 50 falls within the standard deviation range (35 to 55), this mean the new standard deviation will be smaller than 10.
