Students at Maple school earned $708 selling candles. They want to accumulate $2000 for a club trio. What percent of their goal

Sholpan [36]

Answer:

The correct answer is 35.4%

Step-by-step explanation:

Let's check the information provided in the question:

Savings goal = US$ 2,000 for the club trip

Earnings for the candles selling = US$ 708

For calculating the accumulated percentage, we can do it this way:

Accumulated percentage = Earnings / Savings goal

Accumulated percentage = 708 / 2,000 * 100

Accumulated percentage = 0.354 * 100

Accumulated percentage = 35.4%

Students at Maple School has accumulated 35.4% of their savings goal with the candles selling.

A taxi driver can cover a distance of 130.16 miles per gallon per 5 gallons of gas if the same taxi driver travel 60 miles at th

uysha [10]

Answer:

$Gallons = 2.305$

Step-by-step explanation:

Given

Rate = 130.16 miles for 5 gallons

Required

Number of gallons used for a journey of 60 miles

The rate in miles per gallon is calculated as:

$Rate = \frac{Distance}{Gallons}$

When distance = 130.16 and gallons = 5, we have:

$Rate = \frac{130.16}{5}$

$Rate = 26.032$

When distance = 60 miles.

Substitute 60 for distance and 26.032 for rate in $Rate = \frac{Distance}{Gallons}$

$26.032 = \frac{60}{Gallons}$

Cross Multiply

$Gallons * 26.032 = 60$

$Gallons = \frac{60}{26.032}$

$Gallons = 2.305$ --- approximated

15.

boyakko [2]

Explanation:

${3 \choose 2} = \frac{3!}{2!(3-2)!} = \frac{6}{2*1} = 3$

${3 \choose 1} = \frac{3!}{1!(3-1)!} = \frac{6}{1*2} = 3$

b) First, we have that

${n \choose k} = \frac{n!}{k!(n-k)!}$

On the other hand,

${n \choose n-k} = \frac{n!}{(n-k)!(n(n-k))!} = \frac{n!}{(n-k)!k!}$

Therefore, both expressions are equal. This makes sense, because selecting k elements from a group of n is the same than specify which elements you will not select. In order to specify those elements you need to select the n-k elements that will not be selected. Hence, each time you are selecting k from n, you are also selecting n-k from n, and from that reason both combinatorial numbers are equal.
