To find your new number of sales per month, you will need to find the number of sales you have per month (based on 30 days per month).
55 x 20 = 1650 sales.
Than, you will need to calculate what 10% of this is and add it to your original sales number.
0.1 (10%) x 1650 = 165
1650 + 165 = 1815
You will need approximately 1815 sales based on the 30 day month.
Answer:
83.4% or 83%
Step-by-step explanation:
when trying to find a percent, divide the numerator (# of correct answers) by the denominator (# of total questions possible to get correct)
Which would be 16.67 divided by 20 which equals .8335. Move the decimal point over two placements which would be 83.35. I rounded it up to 83.4. If trying to find a whole number not a decimal it would be 84%. Depending on the grading scale, it would be a B.
Answer:0.8413
Step-by-step explanation:
Mean= 188, Std Dev. =20.8, Z=(x-mean)/Std Dev
P(X less than 167.2)= P(Z less than (167.2-188)/20.8)
=P(Z less than (-20.8/20.8))
=P(z less than -1)= P(Z less 1)
The value of 1 in the normal distribution table is 0.3413
So we add 0.5 to 0.3413 =0.8413
