By what percent will a fraction decrease if its numerator is decreased by 50% and its denominator is decreased by 25%?

ioda

Answer:

The fraction will decrease $33.33\%$

Step-by-step explanation:

Let

x/y ----> the fraction

we know that

100%-50^=50%=50/100=0.50

100%-25%=75%=75/100=0.75

substitute

$\frac{x}{y}*\frac{0.50}{0.75} =\frac{2}{3}(\frac{x}{y})$

therefore

The percent that the fraction will decrease is equal to

$(1-\frac{2}{3})*100=33.33\%$

Dean Halverson recently read that full-time college students study 20 hours each week. She decides to do a study at her universi

Answer: The p-value is 0.154.

Step-by-step explanation:

Since we have given that

We claim that

Null hypothesis :

$H_0:\mu=20$

Alternate hypothesis :

$H_1:\mu$

Population mean = 20 hours

Sample mean = 18.5 hours

Sample standard deviation = 4.3 hours

Sample size n = 35

So, test statistic would be

$z=\dfrac{\bar{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\z=\dfrac{18.5-20}{\dfrac{4.3}{\sqrt{35}}}\\\\z=\dfrac{-1.5}{0.726}\\\\z=-2.066$

So, the p value would be 0.154.

Hence, the p-value is 0.154.

The sum of measures of alternate interior angles of two parallel lines is 210°. What are the measures of these angles?

torisob [31]

The answer is 105. Alternate interior angles of two parallel lines are congruent(meaning they are the same). 210/2=105, also the answer has to be below 180 degrees but more than 0.
