He'll spend 138.91 dollars.
First multiply 427 and 231 to find out how much square feet you need to cover. Then divide the number by 3500 to see how many bags of fertilizer you need. Since there is a remainder, he'll have to buy another bag. Then, multiply the number of bags needed with the price of each bag to get the amount of money spent.
Answer:
m< LMJ=119.6 degrees
Step-by-step explanation:
In parallel lines, m<LMO and m< LMJ are supplementary. So that means that they add up to 180 degrees. If , m<LMO is 60.4 degrees, m< LMJ would be 180 degrees minus 60.4 degrees which equals to 119.6 degrees.
If you change the decimal to a fraction you will be able to tell be cause a proportion is basically a fractional part
Using the z-distribution, it is found that the smallest sample size required is given by:
B) 7 vehicles.
<h3>What is the margin of error for a z-distribution confidence interval?</h3>
It is given by:
In which:
is the population standard deviation.
In this problem, we have a 90% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.645.
The margin of error and the population standard deviation are given by, respectively:
.
Then, we solve for n to find the needed sample size.
Rounding up, 7 vehicles have to be sampled, hence option B is correct.

Answer:
10 bracelets
Step-by-step explanation:
we need to convert 5 ft to inches
1 ft = 12 inches
multiply by 5
5 ft = 60 inches
60 inches of yarn, 6 inches per bracelet
60/6 = 10
10 bracelets
