Money in a bank triples every 10 years. If $100 is deposited today, what will its value be after 40 years? PLEASE SHOW ME STEP B

LenKa [72]

Answer:

d) $8,100

Step-by-step explanation:

Given information:

Money triples every 10 years
Initial deposit = $100
Number of years invested = 40 years

If the money triples (multiplies by 3) every 10 years,
then in 40 years time it will triple 4 times, as 40 ÷ 10 = 4

⇒ Account balance after 40 years = $100 × 3 × 3 × 3 × 3

= $100 × 3⁴

= $8,100

Proof

In 10 years time the balance of the account will be:

$100 x 3 = $300

In another 10 years time, the balance of the account will be:

$300 x 3 = $900

In another 10 years time, the balance of the account will be:

$900 x 3 = $2700

In another 10 years time, the balance of the account will be:

$2700 x 3 = $8100

A spring stretches by 21.0 cm when a 135 n object is attached. what is the weight of a fish that would stretch the spring by 49

Akimi4 [234]

If the stretch is proportional to the weight, it will satisfy
weight/(49 cm) = (135 N)/(21 cm)
weight = (49/21)×135 N
weight = 315 N

The weight of the fish would be 315 N.

What is the probability that the number of “HEADs” on these four coins is equal to 3? (4 points)

slavikrds [6]

Answer:

a. $\frac{1}{4}$

Step-by-step explanation:

We are asked to find the probability of getting 3 heads on 4 flips.

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$

Since we know that flipping a fair coin has 2 equally likely possible outcomes, so flipping four coins will have $2*2*2*2=16$ possible outcomes.

Sample space of possible outcomes.

HHHH, HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, HTTT,

THHH, THHT, THTH,THTT, TTHH, TTHT, TTTH, TTTT.

We can see that there are 4 favorable outcomes of getting heads.

$\text{Probability of getting 3 heads}=\frac{4}{16}$

$\text{Probability of getting 3 heads}=\frac{1}{4}$

Therefore, the probability of getting 3 heads on 4 coins will be $\frac{1}{4}$ and option a is the correct choice.
