    x + y = 4(1 + y) + y = 4        1 + 2y = 4  1 - 1 + 2y = 4               2y = 4                 y = 2

-x = -1 + y-x = -1 +2
-x = 1
.... that's as far I can go... sorry

The team won 18 of its 30 games. What was the team’s won-lost ratio?
NemiM [27]

Answer:

18:12 (accurate)

3:2 (simplified)

Step-by-step explanation:

The team won 18 games out of 30 total games. Find the amount of games lost by simply subtracting 18 with 30:

30 - 18 = 12

The ratio you are trying to find is won to lost, or won:lost. Plug in the corresponding numbers to the corresponding terms:

won:lost ⇒ 18:12

18:12 is the ratio.

If the teacher asks you to simplify, factor both sides. Divide 6 from both sides:

(18)/6 : (12)/6

3:2

3:2 is your simplified ratio.

Sal places $500 in a retirement account that offers a return of 3.5% compounded annually . He will not deposit or withdraw any m
Tju [1.3M]

Answer:

f(t) = 500 * (1.035) ^ t

Step-by-step explanation:

A = p(1 + r/n)^nt

Where

A = future value = ?

P = principal = $500

r = interest rate = 3.5% = 0.035

n = number of periods = 1

t = number of years = t

A = p(1 + r/n)^nt

= 500(1 + 0.035/1)^1*t

= 500(1 + 0.035) ^t

= 500( 1.035)^t

= 500 * (1.035)^t

f(t) = 500 * (1.035) ^ t

Talia tossed a penny many times. She got 30 heads and 70 tails. She said the experimental probability of getting heads was 30 70
-BARSIC- [3]

Answer:

The experimental probability of landing on heads is 0.3

Step-by-step explanation:

We are given the following in the question:

Number of heads = 30

Number of tails = 70

Talia said the probability of getting heads is \frac{30}{70}.

She evaluated the wrong probability.

She did not considered total number of trials in the experiment.

Formula for probability:

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

Probability of heads =

P(H) = \dfrac{30}{30+70} = \dfrac{30}{100} =0.3

The experimental probability of landing on heads is 0.3
