O si it told me that the solution was -1/2,x2 and it equals =1/2 hope it helps
Answer:
50
Step-by-step explanation:
9. There are 4 odd numbers and 4 even numbers
P(odd number) = odd numbers/ total
= 4/ (4+4)
=4/8
= 1/2
If we spin 100 times, we multiply the number of times we spin * the probability
100 * 1/2 = 50
Answer:
a. 5% of the employees will experience lost-time accidents in both years
b. 24% of the employees will suffer at least one lost-time accident over the two-year period
Step-by-step explanation:
a. What percentage of the employees will experience lost-time accidents in both years?
20% last year, of those who suffered last year, 25% during this year. So

5% of the employees will experience lost-time accidents in both years.
b. What percentage of the employees will suffer at least one lost-time accident over the two-year period?
5% during the two years.
10% during the current year. 25% of employees who had lost-time accidents last year will experience a lost-time accident during the current year.
So the 10% is composed of 5% during both years(25% of 20%) and 5% of the 80% who did not suffer during the first year.
First year yes, not on the second.
75% of 20%. So, total:

24% of the employees will suffer at least one lost-time accident over the two-year period
You can calculate it using the law of cosines: c^2=a^2+b^2-2*a*b*cos(C)
your triangle is
CD=15=a
CE=?=b
DE=CE+3=b+3=c
and C=90°
-> insert those values, with c substituted with b+3 to remove c
c^2=a^2+b^2-2*a*b*cos(C)
(b+3)^2=15^2+b^2-2*15*b*cos(90)
cos(90)=0->
(b+3)^2=15^2+b^2
b^2+2*3*b+3^2=225+b^2
6b+9=225
6b=216
b=36=CE
DE=CE+3=36+3=39
Answer: No it is <u>not</u> a solution
Why not? Because it doesn't make the first inequality true. Replace x with 1 and y with 2
y > 2x
y > 2*1 ... replaced x with 1
2 > 2*1 .... replaced y with 2
2 > 2 .... which is a false inequality statement since 2 is not larger than itself
