Hello there! For this word problem we first have to identify the numbers and variables if there are any. Our numbers are 36 cents per 23 ounces, each sample weighs 69 ouches, and how much it costs to mail out one hundred eighty-eight.
Next, let's see how many 23 ounces are in 69 ounces. To solve for that, we can divide 69 by 23. 63 divided by 23 is 3, so there is 3 sets of 23 ounces per 69 ounce samples. Then, we can multiply 3 by 36 cents in order to see how much each sample costs. 3 times .36 is 1.08 or 1 dollar and 8 cents. Lastly, we need to multiply 188 by 1.08 to figure out how much it costs to mail out 188 samples.
188 times 1.08 equals to 203.04 or 203 dollars and 4 cents. Therefore, it would cost $203.04 to mail out 188 samples. Hope this helps! Have a great day!
You can take the amount Sara collected and subtract the amount that Pierre collected to get the answer. Sara collected 244 more cans than Pierre.
Answer:
a) how much difference in number of mean is 2.2
b) standard error of sample mean = 0.8
c) the test statstistical value is greater than the critical value ,hence we reject the null hypothesis. we can conclude that the treatment thus have a significant effect
Step-by-step explanation:
C. 5:6:10 Explanation: since they all have a common dividend of 7, u just have to divide all of them by 7 :)
You would need to do this with a graphing calculator
