The expression for the money deposited in the bank is 500 + 40m and it will take 7 months to get the required amount.
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.

What is the degree of the polynomial?
Answer:
the degree of the polynomial given is 1
Step-by-step explanation:
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?
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)
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.
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.
