Answer:
The Answer is: x / y = 8 / 3
Step-by-step explanation:
3(x - 2) - 4(2y - 1) + 2=0
3x - 6 - 8y + 4 + 2 = 0
3x - 8y = 0
3x = 8y
3x/y = 8
x / y = 8 / 3

Answer:
B
Step-by-step explanation:
The min and max numbers are 5.5 and 8.5. To find range, you subtract the bigger number by the smaller number. To find midrange, you find the median of the 2 min and max numbers.
8.5-5.5=3
5.5 6 6.5 7 7.5 8 8.5
1 2 3 4 5 6 7
So the range is 3 and the midrange is 7.

Answer:
The confidence interval is from 69.82 o 82.18
Step-by-step explanation:
Using this formula X ± Z (s/√n)
Where
X = 76 --------------------------Mean
S = Standard Deviation
If Variance = 144
S = √144
S = 12
n = 25 ----------------------------------Number of observation
Z = 2.576 ------------------------------The chosen Z-value from the confidence table below
Confidence Interval || Z
80%. || 1.282
85% || 1.440
90%. || 1.645
95%. || 1.960
99%. || 2.576
99.5%. || 2.807
99.9%. || 3.291
Substituting these values in the formula
Confidence Interval (CI) = 76 ± 2.576 (12/√25)
CI = 76 ± 2.576(12/5)
CI = 76 ± 2.576(2.4)
CI = 76 ± 6.1824
CI = 76 + 6.1824 ~ 76 - 6.1824
CI = 82.1824 ~ 69.8176
CI = 82.18 ~ 69.82
In other words the confidence interval is from 69.8176 to 82.1824
1 cup of milk = 8 g proteins
2.5 cups of milk = 2.5 * proteins present in 1 cup of milk
= 2.5 * 8
= 20 g
20 grams of proteins is present in 2.5 cups of milk.
