The slope is basically the coefficient of x and that is 1 since 1x=x. To find the y-intercept, you need to subtitute x=0 into y=x+5 because x is at 0 when you are looking at the y-intercept.
y=0+5=5
So the slope is 1 and the y-intercept is 5.
Answer:
1.2378×104
Step-by-step explanation:
The number 10 is called the base because it is this number that is raised to the power n. Although a base number may have values other than 10, the base number in scientific notation is always 10.
Answer:
The number of defective bulbs in the shipment should be around 15, give or take 4.
Step-by-step explanation:
For each bulb, there are only two possible outcomes. Either it is defective, or it is not. The probability of a bulb being defective is independent of any other bulb. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:

The standard deviation of the binomial distribution is:

Suppose the probability at a light bulb factory of a bulb being defective is 0.11
This means that 
Shipment of 133 bulbs:
This means that 
Mean and standard deviation:


Rounding to the nearest integers:
The number of defective bulbs in the shipment should be around 15, give or take 4.
Answer:
Step-by-step explanation:
-3x<9
+3x to ech side
0<9+3x
-9<3x
-3<x
or x>-3
Answer:
B.
Step-by-step explanation:
P(something not happening)+P(something happening)=1 or 100%.
So if we have
P(something not happening)+40%=100%
Then the P(something not happening)=60% since 60%+40%=100%.
Yes I was using the event="something not happening" as the complement of something happening.
In fancy notation, some people might write:
