Quartile Q 1 = 110. We have to find how many of electricians have score 110 or less.
For Q 1 : 25 % of the scores are below this value. The area under the bell-shaped curve of the normal distribution is 0.25. And since we have 288 electricians that took a certification test:
0.25 * 288 = 72.
Answer: 72 electricians had a score of 110 and less.
Answer: The distance is 17.
Step-by-step explanation:
Find their difference in the y values and the difference in the x values then find their absolute values.
2-17 = -15
-6 - 2 = -8
The absolute value of -15 is 15 and the absolute value of -8 is 8.
Now square them and add them up to find their square root.
15^2 + 8^2 = c^2
225 + 64 = c^2
289= c^2
c= 17
So you need to add 6n with +2 then 5-7
Well 25 is = to 1/4 of 100
so is 23 is 1/4 of the amount in the bag.
multiply 23 by 4 and that should get 92.
I hope that that was correct. I'm kinda new at this.
The domain is 0 < n < 75 (The maximum amount of cars is 75) also those are GREATER THEN OR EQUAL TO, not greater than
