Please help me , I have been try to solve it for 2 hours. thank you very much.

Alexxandr [17]

Answer:

See the three answers with their explanation below

Explanation:

a. To eliminate the fraction from each side you multiply both sides by the least common denominator of the fractions of the two sides.

In this case it is 2×3 = 6

See how you do it:

$6\times \frac{1}{2}(x-4)=6\times \frac{1}{3}x+6\times 2\\ \\ 3(x-4)=2x+12$

b. This word problem would lead to the given equation:

Half the age of Alice 4 years ago equals 2 more than one third of her current age.

Current age: x
Age four years ago: x - 4
Half the age of Alice four years ago: $\frac{1}{2}(x-4)$

2 more than one third of her current age: $2+\frac{1}{3}x=\frac{1}{3}x+2$

Equality condition:

$\frac{1}{2}(x-4)=\frac{1}{3}x+2$

c. Solution

$\frac{1}{2}(x-4)=\frac{1}{3}x+2\\ \\ 3(x-4)=2x+12\\ \\ 3x-12=2x+12\\ \\ x=24$

Meaning: Alice is currently 24 years old.

What is the difference between confidence level and confidence interval.

Mazyrski [523]

Answer:

The confidence level is the percentage of times you expect to get close to the same estimate if you run your experiment again or resample the population in the same way. The confidence interval consists of the upper and lower bounds of the estimate you expect to find at a given level of confidence.
