Answer:
divide both sides by 1.57 so
x=0.636943y
The integer is always negative or a fraction
Answer:
Step-by-step explanation:
The two ringtones will cost her a total of 
and is a fixed amount. The relationship between the cost and number of songs only is 
and therefore the answer is 
. You can also directly find the answer by finding the y-intercept (in this case 
), as no other answer choices include the term , so A must be the correct answer.
Answer:
0.03593
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 17,340
μ is the population mean = 15,000
σ is the population standard deviation = 1300
z score:
z = 17340 - 15000/1300
z =1.8
Probability value from Z-Table:
P(x<17340) = 0.96407
P(x >17340) = 1 - P(x<17340)
= 1 - 0.96407
= 0.03593
The probability that the life span of the monitor will be more than 17,340 hours is 0.03593
A. 20. plug 20 in to both equations and they will be equal to eachother
