The standard deviation of the lifespan of a certain brand of LED light bulbs is 23 months. The quality control department at this company takes a random sample of 75 LED light bulbs and finds the mean lifespan of sample is 135 months. What is the probability that this sample mean is within 1 months of the mean of all light bulbs produced by the company

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

current in the circuit at time t is /, then the power delivered to the resistor is

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
