Answer:
No we can consider A as single event. See the explanation below
Step-by-step explanation:
Let's define the event A as:
A=" Select a 4 from a standard deck of 52 cards"
We know that in a standard deck we have 4 different types of 4, spade, heart, diamond and club.
And by definition of simple event we need to have just one possible outcome in the experiment, and on this case we have 4 possible options for event A, so for this reason the event A can't be considered as simpl event.
To calculate this, we need to do the following:
92 * 115 = 10580 (we first multiply the percentage with our number)
10580 / 100 = 105.8 (and divide what we get by 100 to get the final answer)
And this is also already the answer: 105.8
Answer:
- Elanor's standardized score is 1.19
- Gerald's standardized score is 0.72
- Elanor has higher score
Step-by-step explanation:
To compare Elanor's and Gerald's math scores, we need to standardize them and calculate their z-scores.
z score can be calculated using the formula
z=
where
- M is the mean score of the exam
- s is the standard deviation of the exam
Elanor's standardized score is:
z(e) = 
≈ 1.19
Gerald's standardized score is:
z(g)= 
≈ 0.72
Since z(e) > z(g), Elanor has higher score
Answer:
It has to be a single digit between 1 and 10
Answer:
y = 2
Step-by-step explanation:
-3y + 6 = 0
-3y = -6
y = -6/-3
y = 6/3
y = 2
