The conversion between these units is 1 km/hr = 0.62 m/hr

Answer:

m = 0.6k

Step-by-step explanation:

When an object has a speed of k kilometers per hour or m miles per hour, the relationship between k and m can be expressed as

\frac{m}{k}=c where c is a constant.

Substituting k = 100 km/hr and m = 62 mph allows us to figure out the value of c k.

\frac{62}{100}=c

c = 0.62 ≈ 0.6

This leads us to the equation \frac{m}{k}=0.6

Or m = 0.6k

1 kilometer per hour equals 0.6 miles per hour

Matt invested $1500 into a stock of his choice. After two years, he had received
Leona [12618]

For this query, the time presented seems unclear to me. I understand that the rate of return is determined by total return over the investment. Assuming Matt received $400 as dividends without reinvesting them into additional shares, his total return across two years amounted to $500. Conversely, if the dividends were reinvested into the stock—something that typically happens with a 401(k) or IRA—his ROI would render a mere 6% due to only a $100 gain on a $1500 investment. In an actual market scenario, it’s likely that Matt would have experienced about a 5% return on a solid stock, while Bella would have had approximately 0.05% from a savings account.

I hope this was helpful!;)

Amanda is a cabinetmaker. She makes cabinets using one of three types of wood: birch, maple, or cherry. She can finish each type
PIT_PIT [12445]
Assuming that every material in their respective categories has an equal likelihood of selection.

Categories:
(a) Wood types for cabinets: birch, maple, cherry.
Each wood type has a selection probability of 1/3.
(b) Finish types: transparent, semi-transparent.
Each finish type has a 1/2 chance of being selected.
(c) Knob types: bronze, steel, wood.
Each knob material carries a probability of 1/3.

The selection of materials for the cabinet, finish, and knobs is independent of one another.

Consequently,
Probability(birch wood AND bronze knob) = (1/3)*(1/3) = 1/9
Probability(wood knob) = 1/3
Probability(transparent stain) = 1/2
Probability(cherry wood AND semi-transparent stain) = (1/3)*(1/2) = 1/6
