Answer:
12.5
Step-by-step explanation:
If the number of workers injured in each accident is i<em>ndependent </em>of the number of accidents that occur, <em>then the expected number of workers injured in a week equals the expected number of accidents per week times the expected number of workers injured in each accident.
</em>
But the expected number of workers injured in each accident is precisely the average or mean, so
<em>Expected number of workers injured in a week = 5*2.5 = 12.5.
</em>
Or in other words, in 10 weeks there will probably be 125 workers injured.

Answer:
(See bolded numbers)
<u>Factoring</u><u> -1 out of negative numbers</u><u>:</u>
11) (-6) • (3)= (-1 • 6) • 3= -1 • 6 • 3= -18
-6 is the negative number here and factoring out -1 from -6 will give us -1(6). In the second last step, multiply 6 and 3 together then multiply the product by -1.
-1(6 ×3)= -1(18)= -18
12) (-4) • (-8)= (-1 • 4) • (-1 • 8)= 1 • 4 • 8= 32
Multiplying 2 negative numbers will give us a positive number. The 3rd step is 1 as (-1)(-1)= 1.
13) (-9) • (-5)= (-1 • 9) • (-1 • 5)= 1 • 9 • 5= 45
14) (2) • (-8)= 2 • (-1 • 8)= -1 • 2 • 8= -16
Negative numbers are numbers with a negative sign and are numbers less than zero. Factoring -1 out of negative numbers will leave us with the positive number.
Answer:
3
Step-by-step explanation:
Period of a function is the period after which the function attains the same value
in the graph attached with this problem we can see that
f(0)=1
the value of x for which function f(x) attains the value 1 again is at
x=3
f(3)=1
similarly , we see
f(6)=1 , f(9)=1
Hence we see that after every increased value of x by 3 units , we attain the same value of function . hence the period of the function is 3
