a decimal

2/3 = 0.7

9/2 =  4.5

-11/3 = -3.7

13/5 = 2.6

-7/4 = -1.8

Esto es solo un bosquejo del número, usando un gráfico, use 0.1 para una unidad en la recta numérica.

Hope is the coach of the Wilson High School girls' soccer team. There are 3 minutes left in the game they are currently playing,
NISA [10]

To answer this question, we need to find the winning probability in either case.

Probability = no. of outcomes / total no. of possible outcomes

<u>When Hope pulled her defender :</u>

Total no. of games = 9

No. of games won = 3

Winning probability = 3/9 =1/3

<u>When Hope left her defender :</u>

Total no. of games = 10

No. of games won = 6

Winning probability = 6/10 = 3/5

We know that , 1/3 < 3/5.

So, Hope should not pull her defender, as the winning probability is better when Hope left her defender.

Answer : A. Hope should not pull her defender.

kayden paddled a canoe to an island. the island is 8 miles from the shore. his trip to the island took two hours while paddling
Andrew [12]

Answer:

2\text{ mph}

Step-by-step explanation:

GIVEN: kayden paddled a canoe to an island. the island is 8 miles from the shore. his trip to the island took two hours while paddling against the current. he paddles 6 mph with no current.

TO FIND: what was the speed of the current.

SOLUTION:

distance of island from the shore =8 miles

total time taken by Kayden =2 hours

speed of Kayden in still water =6\text{ mph}

Let the speed of current be x

Speed of Kayden against current =6-x\text{ mph}

As,

\text{Time}=\frac{\text{Distance}}{\text{speed}}

2=\frac{8}{6-x}

12-2x=8

x=2\text{ mph}

Hence speed of current is 2\text{ mph}
