6 - r = 2 (subtract 6 from both sides)
Your left with: -r = -4 (divide each side by -1)
Answer: r = 4

Answer $39.75
Explanation: $5.49 (hamburgers) x 2 = $10.98
chicken sandwich is $6.25 and ribs are $12.99
$1.75 (sodas) x 4 = 7
$10.98 + $12.99 + $7 = $30.97
7 percent tax is $2.16 so $30.97 + $2.16 = $33.13
20 percent of $33.13 is $6.62 so $33.13 + $6.62 = $39.75
Answer:
Based on the confidence interval, Sheldon's claim is plausible
Step-by-step explanation:
The number of customers in the sample, n = 620 customers
The number of customers that replied that they had moved at least once in the last five years = 201 (32.4%)
The 90% confidence interval for the sample = (0.293, 0.355)
Let 'p' represent the proportion of all customers who have moved in the past five years
The proportion of customers Sheldon claimed have moved in the past five years, p > 1 in 4 (0.25)
The proportion Zachary urges Sheldon to claim is, p > 1 in 3 (0.)
Given that the lower estimate of the confidence interval is 0.293 (>0.25) and upper bound of the confidence interval is 0.355 (> 0.), and that 0.26 in also more than 1 in 4 but less than 0.293, but however that 0.293 which is within the 90% confidence interval is less than 0. or 1 in 3, as opposed to what Zachary urges Sheldon to claim, Sheldon's claim is more plausible.
