It would equal to 12.7 cm because an inch equals 2.54 cm.
Step-by-step explanation:
Formula: z = (x-μ)/σ
So, plug in the numbers.
N(14,4), find the z score for 9
x is the number you're finding, so x=9
μ is the mean, so μ = 14
σ is the st. deviation, so σ=4
Plug them in, so it's z=(9-14)/4 and you'll get your answer :)
hint: it should be a negative number
Answer:
x = 20
Explanation:
Let's solve your equation step-by-step.
−10x = −200
