Answer:
D. 59.50$
Step-by-step explanation:
Lets make an equation:
we know she is going to use 2 parts of yellow to 3 parts of red and she needs 10 quarts, therefore the equation would be:
2x+3x=10
x = 2
2 * 2 = 4( we need four quarts of yellow paint)
Price for yellow paint = 4 * 5.50 = 22
2 * 3 = 6(we need 6 quarts of red paint)
Price for red paint = 6 * 6.25 37.5
Add those prices: 37.5 + 22 = 59.50$
(9,0)
X=8+1=9
Y=2-2=0

Answer: (97.63, 99.77)
Step-by-step explanation:
Given the data:
99.6 99.7 97.9 98.6 97.7
Using calculator, we can obtain the mean and standard deviation of the sample data:
Mean(m) = 98.7
Standard deviation = 0.93
Sample size (n) = 5
Using the relation to find confidence interval :
Mean ± Zcrit * (s/√n)
Zcrit at 99% = 2.576
98.7 ± 2.576 * (0.93 / √5)
Lower limit : 98.7 - (2.576 * 0.4159086) = 97.6286194464 = 97.63 ( 1 decimal place)
Upper limit : 98.7 + (2.576 * 0.4159086) = 99.7713805536 = 99.77 ( 1 decimal place)
(97.6, 99.8)
