Answer:
The estimated profit is 62.784
Step-by-step explanation:
y = 4.009x - 77.531
Plug in the number of pizzas sold for x:
y = 4.009(35) - 77.531 = 140.315 - 77.531 = 62.784
Answer: The answer came out to 1105.19 so the answer would be about 1105 people bought the Nintendo game.
Explanation: To find the number of people using percentages, you would do 0.37 (you have to convert the percent to a decimal) times 2987.
I hope this helps , and if you have anymore questions feel free to message me! (:
D and b i think because i know the other answers are wrong lol
step 1
<span>compute the average: add the values and divide by 6
Average =(44+ 46+40+34+29+41)/6=39
step 2
</span><span>Compute the deviations from the average
dev: (44-39)=5,
</span>dev: (46-39)=7
dev: (40-39)=1
dev: (34-39)=-5
dev: (29-39)=-10
dev: (41-39)=2
step 3
<span>Square the deviations and add
sum (dev^2): 5^2+7^2+1</span>^2+-5^2+-10^2+2^2
sum (dev^2): 25+49+1+25+100+4-----> 204
step 4
<span>Divide step #3 by the sample size=6
(typically you divide by sample size-1 to get the sample standard deviation,
but you are assuming the 6 values are the population,
so
no need to subtract 1, from the sample size.
This result is the variance
Variance =204/6=34
step 5
</span><span>Standard deviation = sqrt(variance)
standard deviation= </span>√<span>(34)------> 5.83
the answer is
5.83</span>
