Step-by-step explanation:
Let 'P' represent the principal amount
'R' will stand for the interest rate
'T' indicates the time period
P = $1000
R = 3%
T = 4 years
We can compute the simple interest using,
Interest = (P x R x T) / 100
= (1000 x 3 x 4) / 100
= 12000 / 100
= $120
Thus, the simple interest over 4 years totals $120.
Total amount = P + Interest
= 1000 + 120
= $1120
Consequently, the account will have $1120 after 4 years.
Because each share was originally purchased at 20 1/4, the gain per share when the price rises to 25 1/4 is (25 1/4 - 20 1/4) = $5.00. Selling 30 shares therefore yields a total profit of (30 x 5) = $150.00. Thus, the correct choice is C<span>.</span>
Initially, you must determine the unknown measurements. The actual angle measurements in the hexagon are not specified; however, an expression is provided. First, solve for x to substitute it into the angle measurement. You should set the two provided sides equal: 20x+48=33x+9. After finding x, use it to calculate each angle measurement, leading to 108. Since the hexagon is regular, all angles are equal. Observing the angle at the top exposes two triangles and the angle itself. As it forms a straight line, the total equals 180. You already know the hexagon's angle measurement and lack the triangle measurements. Therefore, 180-108=72. The missing angle part is 72. To find each triangle's angle measurement, divide this by 2, resulting in 36 degrees.
Options
- Counting rule for permutations
- Counting rule for multiple-step experiments
- Counting rule for combinations
- Counting rule for independent events
Answer:
(C) Counting rule for combinations
Step-by-step explanation:
To find the number of outcomes when selecting n objects from N objects, we apply either permutation or combination.
- If the order of selection matters, we utilize permutation.
- On the other hand, if the order of selection does not matter, we opt for combination.
Thus, the counting method employed for determining experimental outcomes when selecting n objects from N objects without regard to selection order is referred to as the counting rule for combinations.
