Answer:
0.0548
Step-by-step explanation:
The distribution of life span for a certain type of battery is approximately normal with mean 2.5 hours and standard deviation 0.25 hour.
To find the the probability that a selected battery will have a life span of at most 2.1 hours, we need to first determine the z-score for x=2.1 hours using
We substitute the values to get:
We read read -1.6 from the standard normal distribution table to get:
P(X≤2.1)=0.0548
Look for a relationship between the input “X” side, and the output “Y” side. Check thepattern<span> against every row. It has to be true for the whole table, or it's not the </span>rule<span>. Use the </span>rule<span>, and the numbers you </span>know<span>, to complete or </span>extend<span> the </span>pattern<span>.</span>
The answer is whole number,rational number and integers
Answer: x+2 and y +2
Step-by-step explanation:
4x2+2=10
8+2=10
Answer:
Add the exponents
Step-by-step explanation:
Product Rule: am ∙ an = am + n, this says that to multiply two exponents with the same base, you keep the base and add the powers.
EX:
x multiplied by x^5=x^6
