The expression for the money deposited in the bank is 500 + 40m and it will take 7 months to get the required amount.
What is compound interest?
The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.
(A) The balance of Raj's account is given as $500.
And, the money deposited every month is $40.
Suppose, the number of months be m.
Then, the following expression can be written for money in account as,
500 + 40m.
(B) The equation for the given case can be written as,
500 + 40m = 780
⇒ 40m = 280
⇒ m = 7
Hence, the required expression is 500 + 40m number of months required is 7.

mean number of points Holly scores is 20 with
a standard deviation of 2. The mean number
of points Juanita scores is 12 with a standard
deviation of 1.25. Whose score is better relative
to her average number of points per game?
Answers
Answer:
Juanita's score was better
Step-by-step explanation:
Juanita scored 6.4 points above her average score whereas Holly only scored 2.5 points above her average score. (this was calculated via z-scores)
Final answer:
To find who performed better relative to their average, we calculated the z-scores of both players. Juanita's score was 3.2 standard deviations above her mean, whereas Holly's was 2.5 standard deviations above her mean, making Juanita's performance relatively better.
Explanation:
To answer this question, we need to find how many standard deviations each player's score deviates from their respective means. This is referred to as the z-score. The z-score is calculated using the formula (X - μ) / σ, where X is the score, μ is the mean score and σ is the standard deviation.
For Holly, her z-score would be (25 - 20) / 2 = 2.5. This means Holly's score was 2.5 standard deviations above her mean score.
For Juanita, her z-score would be (16 - 12) / 1.25 = 3.2. This means Juanita's score was 3.2 standard deviations above her mean score.
Since Juanita's z-score is higher than Holly's, Juanita's score is better relative to her average number of points per game.
