4 2/3 think of how many time you can put 3 into 14 the section out the rest
X=1.464102
Simplifies to: (1/2x)+1=1.732051
Step 1: Subtract 1 from both sides.
1/2x + 1 -1=1.732051-1
(1/2x)=0.732051
Step 2: Multiply both sides by 2
2*(1/2x) = (2) * (0.732051)
X=1.464102
Answer:
30
Step-by-step explanation:
The sample size should be 30 for the given confidence interval of 90%.
Sample size is calculated as follows:
Sample size = Z score ^2 * standard deviation * [ 1 - Standard deviation] / margin of error^2
For the given 90% confidence level, the sample size calculated as;
Sample size = 1.645^2 * 2.3 [1 - 2.3] / 0.01^2
sample size = 30.

m angle 1 = 120° (linear pair)
Answer:
There were 48 ounces of milk left
Step-by-step explanation:
∵ Lessils used 25% of half a gallon of milk
→ Assume that the total amount of the milk is 25%
∴ The amount of milk left = 100% - 25% = 75%
∵ Half gallon = 64 ounces
→ That means the amount of milk left is 75% of 64 ounces
∴ The amount of milk left = 75% × 64
→ Divide 75% by 100 to change it to decimal
∵ 75% = 75 ÷ 100 = 0.75
∴ The amount of milk left = 0.75 × 64
∴ The amount of milk left = 48 ounces
∴ There were 48 ounces of milk left
