Equation: 120 ≥ 10n + 20

Subtract 20 from both sides, 

100 ≥ 10n

Divide both sides by 10, 
10 ≥ n

It means, it is equal or Smaller than 10.

So, the answers would be: 7, 8, 9, 10

Hope this helps!

Hello there.

Question: <span>Click on all the values for n that make this inequality true. 

Answer: The inequality states that 10 times a number plus 20 is equal to or smaller than 120.
120 - 20 = 100.
Therefore whichever value it is needs to be 10 or below.
10 x 10 = 100
100 + 20 = 120.
Anything below 10 would for this inequality.

In short, Your answers are  7 , 8 , 9 and 10

Hope This Helps You!
Good Luck Studying ^-^</span>

A bag contains two coins, one for which the probability of heads is equal to 1 and one for which the probability of heads is equ
wlad13 [49]

Answer: Option E is the correct answer; (1 + p⁴) / (1 + p³)

Step-by-step explanation:

P (3 head) = P(first and 3 heads) + P(second coin and 3 heads)

= (1/2)×1³ + (1/2)× p³ = (1/2) × (1 + p³)

therefore P(first coin given 3 heads) = (1/2)×1³/ ((1/2)×(1 + p³))

= 1 / (1 + p³)

Also P( second coin given 3 heads) = p³ /(1 + p³)

therefore P(4th toss in heads given first 3 are heads)  will be;

= P(first and 4th toss heads) + P(second and 4th toss heads)

=(1/( 1 + p³ )) × 1 + p³ / (1+p³) × p

= (1 + p⁴) / (1 + p³)

Therefore Option E is the correct answer

A principle of $2000 is placed ina saving account at 3% APR compounded annually. How much is in the account after one year, two
Kisachek [45]

Answer:

1 year:  $2060

2 years: $2121.80

3 years: $2185.45

Step-by-step explanation:

Compound interest formula is A = P(1 + \frac{r}{n}^{nt) where A is the final amount, P is the initial principal balance, r is the interest rate, n is the number of times interest applied per time period, and t is the number of time periods elapsed. In our case, P would be equal to 2000 dollars, r would be equal to 0.03, for 3 percent, and our n value would just be one, so the final equation is:

2000(1.03)^t

First, let's evaluate t for 1, as in one year.

2000 * 1.03^1 = 2000 x 1.03 = 2060

Two years: 2000 * 1.03 squared = 2121.80

Three years: 2000 * 1.03^3 = 2185.45!

Hope this helps!

Terri played 70 tournament chess games during the school year and won 49 of them. What is her win-to-loss ratio?
Scilla [17]

Alright so the answer would be letter B, because

win-to-loss

49 to 21 (You can determine her losses by subtracted the number of wins from her total number of games played)

Now you must simplify your answer

7 is the greatest common factor (GCF) of both 49 and 21

Now divide both 49 and 21 by 7 to get

7 to 3

Jenny can swim 10 laps In 5 minutes. How many laps should she swim in 1/3 of an hour?
DIA [1.3K]

1/3 of an hour is 20 minutes. If show 10 laps in 5 minutes, just divide 20 by 5, which gives you 4, then multiply 4 times 10. She can swim 40 laps in 1/3 of an hour. Hope that helps. Mark Brainliest if it does. Thank you!
