Answer:
See below
Step-by-step explanation:
The measure of all the arcs can be obtained by using 'Central angle and its corresponding arc theorem'.
1. The measure of arc AD is
2. The measure of arc ABC is
3. The measure of arc ADB is
4. The measure of arc BD is 
P = 10% = 0.1
q = 1 - 0.1 = 0.9
P(at least one defective calculator) = P(1) + P(2) + P(3) + P(4) = 1 - P(0)
The brobability of a binomial distribution is given by

where: n = 4

Therefore,
P(at least one defective calculator) = 1 - 0.6561 = 0.3439
Answer:
Y=1x+2
Step-by-step explanation:
start with the intersept and then add the slope. have you used y+mx+b formula. that should help
8-/x(x-4)/x-3
That should be it if you can’t understand it the whole equation after the eight is a fraction
Answer:
2. increasing when x > 0
the result of root is a positive number
and since there is no value of neg number in roots so it's increasing when x>0
plus in zero it self has a positive number (0,8)
but u cannot find either it's increasing or decreasing in zero bcoz in first derivative test
when x =0
y= not defined
