How many ways can 7 basketball players be listed in order in a program? A. 5,040 B. 720 C. 120 D. 1

Answers

Answer:

A. 5040

Step-by-step explanation:

Number of players of the basketball = 7 and these players are to be listed in order in a program.

Since in any question if order is important then permutation is used and if order does not matters combination is applied.

Therefore for this question where 7 basketball players are to be listed in order, means order matters so permutation is to be used.

$nPr=(n!)/((n-r)!)=7!/(7-7)!=7!/0! = 7! = 7.6.5.4.3.2.1 = 5040$

Therefore option A 5040 is the right answer.

Since the order of basketball players is important, permutation is used. The problem could be interpreted as the permutation of 7 taken 7 at a time

nPr = n! /(n-r)! = 7! /0! = 5040 ways.

The answer is A.

The art museum had a total of 224 visitors on Tuesday. Visitors older than 18 paid $12 for admission. Visitors 18 years or younger paid $8 for admission. The museum collected a total of $2,520. How many visitors were 18 or younger?

Answers

Given:
total of 224 visitors
older than 18 paid $12
18 and below paid $8
total collection 2,520

Let l be visitors older than 18 and m be visitors 18 and below.

l + m = 224
12l + 8m = 2,520

l = 224 - m
12(224 - m) + 8m = 2520
2688 - 12m + 8m = 2520
-4m = 2520 - 2688
-4m = -168
m = -168/-4
m = 42 number of visitors 18 and below.

l = 224 - m
l = 224 - 42
l = 182 number of visitors older than 18.

12(182) + 8(42) = 2520
2184 + 336 = 2520
2520 = 2520

One-fifth of a swarm of bees is resting on a kadaba bush and a third on a silindha bush; three timesthe difference between these two numbers is on a kutaja, and a single bee has flown off in the breeze drawn by the odor of a jasmine and a pandam. Tell me, beautiful maiden, how many bees are there?

Answers

Answer:

There are 15 bees.

Step-by-step explanation:

Let's call x the total number of bees. There is one fifth of that in one bush, which can be written as:

$(1)/(5)x$

there is one third on another, which is:

$(1)/(3) x$

the other one has three times the difference between the previous two:

$3((1)/(3)x-(1)/(5)x)$

So, if we add those three quantities plus one single bee that flew away, it all should add up to the total number of bees, which is x. So:

$3((1)/(3)x-(1)/(5)x)+(1)/(3)x+(1)/(5)x+1=x$

We will solve for x:

$(3)/(3)x-(3)/(5)x+(1)/(3)x+(1)/(5)x+1=x$

$(15)/(15)x-(9)/(15)x+(5)/(15)x+(3)/(15)x+1=x$

$(14)/(15)x+1=x$

We will move the positive x on the right of the equal as a negative one to the left:

$(14)/(15)x-x+1=0$

$(14)/(15)x-(15)/(15)x+1=0$

$-(1)/(15)x+1=0$

$1=(1)/(15)x$

$15=x$

We can prove this answer by replacing in the original equation:

$3((1)/(3)15-(1)/(5)15)+(1)/(3)15+(1)/(5)15+1$

$3(5-3)+5+3+1$

$3(2)+9$

$6+9=15$

Which is an equation in point-slope from for the given point and slope point (-2,4)slope:5

Answers

If we have a point, (x1;y1) and a slope, m, here's the formula we use to find the equation of a line: y - y1 =m( x - x1); where x1 = -2 ; y1 = 4 ; m = 5.
Then, y-4 = 5(x+2);
Finally, y-4 = 5x + 10 / +4
y = 5x + 14 ;

A lamp is on sale, and its price is reduced from $80 to $50. What is the percent of decrease? Select from the drop-down menu to correctly complete the statement.

Answers

The percentage decrease is equal to the change in price ( the decreased amount) divided by the original amount, then multiplied by 100. We have,

Percentage decrease = $(80-50)/(80)=0.375*100=37.5$ %

ANSWER: 37.5%

$80 - $50 = $30

$30 * 100 / $ 80 = 37.5%

answer: 37.5% of decrease.
