What is the explicit formula of a1=-3,d=2

AVprozaik [17]

Answer:

The explicit formula for the given expression is 2 n - 3

Step-by-step explanation:

Here, the first term of sequence = -1

The common difference = 2

In a ARITHMETIC PROGRESSION:

The nth term of a sequence is given as

a(n) = a + (n-1) d

⇒ Here, a(n) = -1 + (n-1)(2)

= -1 + 2n -2

= 2n - 3

or, a(n) = 2n - 3

Hence, the explicit formula for the given expression is 2n - 3.

Calculate annually compounded interest

Hunter-Best [27]

Answer:

$2,851.80

Step-by-step explanation:

Lets use the compound interest formula to solve:

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 1.1% into a decimal:

1.1% -> $\frac{1.1}{100}$ -> 0.011

Next, plug the values into the equation:

$A=2,700(1+\frac{0.011}{1})^{1(5)}$

$A=2,851.80$

She will have $2,851.80 after 5 years.

The heights of adult females are normally distributed. If you were to construct a histogram of 40 randomly selected women, what

Anna11 [10]

Answer:

d. The histogram would be approximately bell-shaped, and the normal quantile plot would have data points have follow a straight-line pattern.

Step-by-step explanation:

Since the variable is normally distributed, the histogram of women's height should be approximately bell shaped (if the data was obtained form a random sample).

Again, the variable is normally distributed, therefore, the quantile plot should follow a straight line pattern (a diagonal line to be more precise).

Amber got a raise, and her hourly wage increased from $8 to $9.50 what is the percent increase

I am Lyosha [343]

Answer:

The percent increase is 18.75%.

Step-by-step explanation:

Given:

Amber got a raise, and her hourly wage increased from $8 to $9.50.

Now, to find percent increase.

Previous wage = $8.

Wage raised = $9.50.

So, to get the increased wage we subtract the previous wage from the wage raised:

$\$9.50-\$8=\$1.50.$

Now, to get the percent increase:

$\frac{1.50}{8} \times 100$

$=\frac{150}{8}$

$=18.75\%.$

Therefore, the percent increase is 18.75%.
