Answer:

2 hours and 29 minutes

Step-by-step explanation:

if you change 9 hours to minutes you get 540 plus 17 equals 557. if you turn 6 hours to minutes it's 360 plus 48 equals 408. 557 minus 408 equals 149 minutes. Now if you convert it to hours and minutes you need to divide by 60. So if you divide it you get 2 hours and 29 minutes. hope this helped! :)

Answer:

The value of <em>n </em>is 15.

Step-by-step explanation:

The combined proportion is computed using the formula:

$P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}$

The information provided is as follows:

$n_{A}=25\\p_{A}=0.56\\n_{B}=n\\p_{B}=0.60\\P=0.575$

Compute the value of <em>n</em> as follows:

$P=\frac{n_{A}\cdot p_{A}+n_{B}\cdot p_{B}}{n_{A}+n_{B}}$

$0.575=\frac{25\times 0.56+n\times 0.60}{25+n}\\\\0.575(25+n)=14+0.60n\\\\14.375+0.575n=14+0.60n\\\\0.60n-0.575n=14.375-14\\\\0.025n=0.375\\\\n=15$

Thus, the value of <em>n </em>is 15.
