The cost of the printer is $309 and cost of the computer is $618.
Step-by-step explanation:
Let x denote the cost of computer
Let y denote the cost of printer
Total cost of printer and computer OR
x + y = $927
<u>To find the cost of x and y,</u>
Cost of computer = 2 x cost of the planet
x = 2y
x+y = 927
2y+y = 927
3y = 927
y = 309
x = 2y
x = 2(309)
x = 618
Therefore, the cost of the printer is $309 and cost of the computer is $618.

Answer:
The z-score for this kernel is -2.3
Step-by-step explanation:
* Lets revise how to find the z-score
- The rule the z-score is z = (x - μ)/σ , where
# x is the score
# μ is the mean
# σ is the standard deviation
* Lets solve the problem
- The popping-times of the kernels in a certain brand of microwave
popcorn are normally distributed
- The mean is 150 seconds
- The standard deviation is 10 seconds
- The first kernel pops is 127 seconds
- We want to find the z-score for this kernel
∵ z-score = (x - μ)/σ
∵ x = 127
∵ μ = 150
∵ σ = 10
∴ z-score = (127 - 150)/10 = -23/10 = -2.3
* The z-score for this kernel is -2.3
