A girl studied for 5 2/3 hours daily. She devotes 2 4/2 hours of her time for science and mathematics. How much time does she de
enot [183]

Given :

Number of hours studied daily , T=5\dfrac{2}{3} .

Time given for science and mathematics is , t=2\dfrac{4}{2} .

To Find :

How much time does she devote for other subjects .

Solution :

Let , time devote for other student is x .

So , Time left for other subject = Total time - Time taken by science and mathematics .

x=T-t\\\\x=5\dfrac{2}{3}-2\dfrac{4}{2}\\\\x=\dfrac{(5\times 3)+2}{3}- \dfrac{(2\times 2 )+4}{2}\\\\x=\dfrac{17}{3}-4\\\\x=\dfrac{17-(4\times 3)}{3}\\\\x=\dfrac{5}{3}=1\dfrac{2}{3}

Therefore , time devote for other subject is 1\dfrac{2}{3} hours .

Hence , this is the required solution .

A researcher testing seed varieties for tulips got a confidence interval of (14.2%,17.4%) for the percent of seeds that can grow
Alex73 [517]

Answer:

The sample proportion is 0.158.

Step-by-step explanation:

In a confidence interval of proportions, we have the lower bound and the upper bound of the interval. The sample proportion is the halfway points between these bounds, that is, the sum of these bounds divided by 2.

In this problem, we have that:

Lower bound: 0.142

Upper bound: 0.174

Sample proportion: (0.142+0.174)/2 = 0.158

The sample proportion is 0.158.
