This is further explained below.
<h3>The graph shows the relationship between the total cost and the number of erasers bought at the student store. Which statement is true?</h3>
Generally, A cost is the worth of the money that has been spent in the process of producing something or delivering a service, and as a result, it is no longer accessible for use.
This concept is utilized in manufacturing, research, retail, and accounting. In the world of business, a cost may refer to a purchase, in which case the sum of money spent on the item in question is considered to be the cost of the item.
In conclusion, each eraser will cost u 50 cents
so 7 erasers will cost (7 * 0.50) = 3.50

Answer: 9.5 hours
In order to solve this, you must divide his total (80.75) by his hourly wage (8.50) When you do that, you get 9.5, so he worked 9.5 hours
Step-by-step explanation:
Answer:
a) 280.4; b) E. Yes, because 300 is greater than mu plus 2 sigma .
Step-by-step explanation:
For part a, we multiply the percentage of murders committed by a firearm by the total number of murders:
0.701(400) = 280.4
This will be the average number of murders by a firearm out of a sample of 400.
Since this is a binomial distribution (two outcomes; independent trials; same probability of success for each trial; and fixed number of trials), the standard deviation is given by
√npq
Since n = 0.701, q = 1-0.701 = 0.299.
This gives us
√(400*0.701*0.299) = √83.8396 = 9.16
This means any unusual values will be less than 2 standard deviations below the mean or more than 2 standard deviations above the mean.
2 standard deviations below the mean will be 280.4-2(9.16) = 280.4-18.32 = 262.08. 300 is not below this value.
2 standard deviations above the mean will be 280.4+298.72. 300 is above this, so it is an unusual value.
First, how much water is required?
Multiply 702 by 1.2 acre ft; the result is 842.2 acre ft of water.
Next, mult. this result by the rate $12.95/acre-ft:
$10909 to water his 702 acres of crops.
