Answer:
304
Step by step:
Using your calculator 5% of 320 is 16.
Since it was a discount, you subtract 16 since you're marking it down.
320-16=304
304 is your answer
How do I know? Well, there it takes 20+20+20+20+20 to equal a hundred. We can do this same math for this problem. 16 x 20 is 320

Answer:
a) Between 74 and 90
b) 81.86% of the scores are between 78 and 90
Step-by-step explanation:
a) According to the Empirical Rule, in a normal distribution, 95% of the data are within 2 standard deviations of the mean. Therefore, the range that 95% of the scores fall in is between 82-4(2)=74 and 82+4(2)=90.
b) The percent of scores that are between 78 and 90 is: normalcdf(lower,upper,μ,σ) = normalcdf(78,90,82,4) = 0.8185946784 ≈ 0.8186, or about 81.86% of the scores.

Answer:
x=-5
Step-by-step explanation:
I did a for #42
2(x-5)=3x+5
simplify
2x-10=3x+5
subtract 2x from both sides
-10=3x+5
subtract 5 from both sides
-15=3x
divide both sides by 3
-5=x
