Answer:
75.94% of the households spent between $5.00 and $9.00 on sugar.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What proportion of the households spent between $5.00 and $9.00 on sugar?
This is the pvalue of Z when X = 9 subtracted by the pvalue of Z when X = 5. So
X = 9
has a pvalue of 0.7611
X = 5
has a pvalue of 0.0017.
So 0.7611 - 0.0017 = 0.7594 = 75.94% of the households spent between $5.00 and $9.00 on sugar.
Yes because 484 + 484 equals 964
And equation you should always do the opposite of the sign you get to find your answer so he got minus he should use Addition

Step-by-step explanation:
Answer:
yes it would beacuse eight is a valid number sorry if it's wrong
Step-by-step explanation:
5x+y=-24x+3y=-2
-24x-5x=-29x
y=-29x+3y=-2
y+3y=4y
4y=-29x=-2
+2 +2
4y=-27
/4 /4
y=-6.75
