your baseball team has won 6 games and lost 4 games. if the team does not lose any more games, how many games must the team win

puteri [66]

Answer:

<em>The team must win 2 games to have a win : loss ratio o 2.</em>

Step-by-step explanation:

<u>Ratio win : loss, r</u>:

r = total wins / total losses

<u>Total wins, Tw</u>:

Call n the number of new wins:

Tw =number of wins until so far + number of new win = 6 + n

<u>Total losses, Tl</u>:

Tl = number of losses so far + number of new losses = 4 + 0 = 4

<u>Target ratio</u>:

r = 2 ⇒ Tw / Tl = (6 + n) / 4 = 2

Solve for n:

(6 + n ) = 4 × 2
6 + n = 8
n = 8 - 6
n = 2

Hence,<em> the team must win 6 more games.</em>

<u>Verification</u>: (6 + 2 ) / 4 = 8 / 4 = 2, which is the target ratio.

Miss Taylor graded 50 English research papers. Twelve of them received a grade of A. Miss Taylor drew a circle graph to display

nikdorinn [45]

<h3>Answer:</h3>

$\large\boxed{24\%}$

<h3>Step-by-step explanation:</h3>

In this question, it's asking you to find how much percentage the circle graph is for "A" papers.

To solve this question, we would need to use information from the question.

Important information:

Graded 50 English research papers
12 of those papers had an "A" grade

With the information above, we can solve the question.

We know that there are 12 research papers that received an A and there are 50 research papers in total.

We would divide 12 by 50 in order to find the percentage of the papers that got an A.

$12\div50=24$

When you divide, you should get 24.

This means that 24% of the circle graph is devoted to "A" papers.

Can someone help me ASAP!!

The answer is 5.

Step-by-step explanation:

To find the interquartile range you must look at the median and the upper and lower halves of the data. The median (12) to the upper half of the data (15) is 3. Next, look at the median (12) to the lower half of the data (10) it is 2. We then add 2 and 3 to get the interquartile range of 5.
