/25 • /2 further written as
5 • /2 simplified form
so A
Answer:
14/20
Explanation:
Sasha tried to get a marble 20 times. 14 of those times she got a yellow marble.
The experimental probability, which is the probability of choosing a yellow marble when Sasha actually tries choosing marbles from the bag.
The theoretical probability is based on the chance that Sasha will get a yellow marble, 7/70, is from the amount of marbles in the bag of yellow colour.
Answer:
Not factorable with rationable numbers
Step-by-step explanation:
You cannot factor this expression with rationable numbers.
A suitable probability calculator can tell you the probability is about 6.7%.
_____
The standard deviation of the distribution of sample means is the population standard deviation (6) divided by the square root of the sample size (√144=12). Thus, your threshold is about (19.25-20)/(6/12) = -1.5 standard deviations from the mean.
Hey there!
Explanation:
First, you had to do is add by 13 from both sides of an equation.

Then, simplify or add by the numbers.


Next, you can also divide by 3 from both sides of an equation.

And finally, simplify and divide by the numbers,

*The answer must have a positive sign.*
