An observation study is where nothing changes and you record what is seen. An experimental study you have a control group and a testable group.

The answer would be: .C. The groups in an experiment are chosen at random, but not in an observational study.

ANSWER

$1,413.81

EXPLANATION

The compound interest formula is given by:

A=P(1+r\%)^t

Where P=900 is the balance in the account, t=10 is the number of years and r=0.0462 is the rate.

We substitute the values in to the formula to get:

A=900(1+4.62\%)^{10}

A=900(1.0462)^{10}

This simplifies to:

A=1413.81

Therefore $1413.81 will be in the account after 10 years.

Given:

Base length of triangle = 40 units

Height of triangle = 9 units

Length of hypotenuse of triangle = 41 units

To find:

Find the value of Tan A

Steps:

Tan of an angle is equal to the opposite length by adjacent length.

So,

Tan A = \frac{opposite}{adjacent}

Tan A = \frac{9}{40}

Tan A = 0.225

Therefore, the exact value of Tan A is 0.225.
