Answer:

Principal = $975

Step-by-step explanation:

Formula for interest is;

I = PRT/100

Where;

P is principal

R is interest rate

T is time

We are given;

I = $195

R = 4%

T = 5 years

Thus, making P the subject of the formula, we have;

P = 100I/RT

P = (100 * 195)/(4 * 5)

P = $975

Answer:

The principal is $975.

Step-by-step explanation:

As per given question we have provided that :

  • ➣ Interest = $195
  • ➣ Rate = 4%
  • ➣ Time = 5 years

Here's the required formula to find the Principal :

{\longrightarrow{\pmb{\tt{I= \dfrac{PRT}{100}}}}}

  • ↝ I = Interest
  • ↝ P = Principal
  • ↝ R = Rate
  • ↝ T = Time

Substituting all the given values in the formula to find the Principal :

{\implies{\sf{I= \dfrac{PRT}{100}}}}

{\implies{\sf{195= \dfrac{P \times 4 \times 5}{100}}}}

{\implies{\sf{195= \dfrac{P \times 20}{100}}}}

{\implies{\sf{195= \dfrac{20P}{100}}}}

{\implies{\sf{P = 195 \times  \dfrac{100}{20}}}}

{\implies{\sf{P = 195 \times  \dfrac{\cancel{100}}{\cancel{20}}}}}

{\implies{\sf{P = 195 \times 5}}}

{\implies{\sf{\underline{\underline{P = \$975}}}}}

Hence, the principal is $975.

In the data set below, what is the mean absolute deviation?
lbvjy [14]

Add the numbers and divide by 5 to get a mean of 6.4

8 - 6.4 = 1.6

4 - 6.4 = -2.4

7 - 6.4 = 0.6

8 - 6.4 = 1.6

5 - 6.4 = -1.4

Add the absolute value of each: 1.6 + 2.4 + 0.6 + 1.6 + 1.4 = 7.6

Divide by 5 = 1.52
