Answer:$4,500
Step-by-step explanation:
Let S be the amount of her sales for the week....and we have:
.05S + 375 = 600 subtract 375 from both sides
.05S = 225 divide both sides by ,05
S = $4500
Answer:
6
Step-by-step explanation:
Hello! We know how many have jumped, which is 36. In all, there are 42. So we can do 42 minus 36, and we get 6! SO 6 people still need to jump.
Answer:
The nuts weigth is 37/16 or 2.3125 pounds.
Step-by-step explanation:
In order to solve this problem we first need to convert all the measurements to the same unit, in this case we will convert ounces to pounds, to do that we need to divide the value by 16, we have:
almonds = 9/16 pounds
We can now convert the weigh of pecans from a mixed fraction to a simple fraction, to do that we sum the integer part to the fraction, we have:
pecans = 1 + 1/8 = 8/8 + 1/8 = 9/8 pounds
We now sum all the weigths:
total weigth = 9/8 + 5/8 + 9/16
Applying LMC we have:
total weigth = (2*9 + 2*5 + 9)/16 = (18 + 10 + 9)/16 = 37/16 = 2.3125 pounds
The nuts weigth is 37/16 or 2.3125 pounds.
Answer:
138
Step-by-step explanation:
Population standard deviation = 
.95 probability of estimating the population mean monthly income within a margin of $20
So, Significance level = 1-0.95 = 0.05
α =0.05
Margin error = 20
Z at 0.05 = 1.96
So, n = 138
Hence sample size should be 138 selected to obtain a .95 probability of estimating the population mean monthly income within a margin of $20
