Answer:

Step-by-step explanation:

The interest accrued is $258.48.

Step-by-step explanation:

Given that:

Initial balance in the savings account = $359

Interest rate = 8%

Time for which no withdrawals or deposits were done = 9 years

To find:

Simple Interest accrued = ?

Solution:

First of all, let us have a look at the formula for simple interest.

Where P is the Principal Amount.

R is the annual rate of interest

T is the time in years.

Here, we are given:

P = $359

R = 8%

T = 9 years

Let us put all the values in the formula:

So, the interest accrued is $258.48.

Which equation contains the points (-1,-8) and (3,4)
katrin [286]

Answer:

y = 3x –5

Step-by-step explanation:

for slope-intercept form, y = mx + b

find the slope, m

(-8 -4)/(-1-3) = m

-12/-4 =m

3 = m

Substitute for m and use either coordinate for y and x to calculate b

4 = 3(3) + b

4 = 9 + b. Subtract 9 from both sides

4 –9 = b

–5 = b. Rewrite the equation with the calculated values for m and b

y = 3x –5

S=[E,F,G,H,J] identify the ways to select two members from s allowing the repetition
Fofino [41]

Answer: There are 25 ways to select two members.

Step-by-step explanation:

Since we have given that

S={E,F,G,H,J}

Number of elements = 5

We need to select two members from S allowing the repetition.

We will use "Fundamental theorem of counting":

There are 5 choices for the first member.

There are 5 choices for the second member.

So, Number of ways would be

5\times 5\\\\=25

Hence, there are 25 ways to select two members.
