Step-by-step explanation:
For each bulb, there are only two possible outcomes. Either they are defective, or they are not. This means that we solve this problem using the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
There are 100 bulbs, so .
3% are defective, so .
a) 0
b) 1
c) 2
d) 3
e) 4
e) 5
Answer:
1/729
Step-by-step explanation:
a negative exponent is fractioned like 1/9^3. Which can be simplified as 1/729 ans 9^3 = 729

Answer:
gradient = 9
Step-by-step explanation:
Note that is a measure of the gradient.
Differentiate y using the power rule
(a) = na
Given
y = x² + 5x - 3, then
= 2x + 5
x = 2 : = 2(2) + 5 = 4 + 5 = 9 ← gradient
Answer:
Step-by-step explanation:
A quick review on PEMDAS, the order of how to solve an equation:
P - parentheses. When parentheses are being used, you have to do everything inside them before doing everything outside of them.
E - exponents. We'll skip these, since there aren't any exponents we need to worry about in this equation.
M/D - multiplication/division. I include these both together because they can be done at the same time.
A/S = addition/subtraction. Can also be done at the same time.
Some other things to note:
You add all the things with an x attached to it, and you add all the things without an x attached to it, and these never cross.
When you bring something from one side of an equal sign to another, you make it negative.
Let's solve for x using what we've learned:
