Answer:
y=10x-5
Step-by-step explanation:
should be the right answer since I used a calculator :p
Answer:
For answer a,
the equation is -1 - 5
this equals -6
From -1 to -6 is 5
A.) The difference is 5
For answer b,
the equation is -7 - (-3)
There are two minus signs by the -3 so that means to turn those two signs into a plus sign
- 7 + 3
Start at -7 and move to the right 3
You will end up at -4
B.) The difference is 3
Answer:
0.5 ; 0.475 ; 0.689 ; 0.4013
Step-by-step explanation:
Given that:
Rate of production of defective batteries p = 0.05
Number of batteries produced (n) = 10
The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries
Variance of defective batteries :
Var(X) = n * p * q ; q = 1 - p
Hence,
Var(X) = 10 * 0.05 * 0.95 = 0.475
Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689
Probability that atleast 1 battery is defective :
Using the binomial probability function
P(x ≥ 1) = 1 - p(x = 0)
= 1 - q^n
= 1 - 0.95^10
= 1 - 0.59873693923837890625
= 0.40126306076162109375
= 0.4013
Answer:
-9
Step-by-step explanation: It crosses the y axis. A y intercept is in when the x axis is 0. So the point would be (0,-9).
