Since the real track has a gauge of 3 feet but the model railroad track has a gauge of 3/4 inches, the scale factor must be 1/4, because you must follow the rule
"true measurement * scale factor = model measurement"
In fact, we have
This implies that the original driving wheels height, 44 inches, must be scaled down to
inches.
Answer:
a) Discrete, because the number of point scored during basket ball is countable.
For instance, the amount of point scored in a basketball could be 75, 103, 63 etc. The numbers are countable
b) Continuous, because the amounts of rainfall is a random variable that is uncountable.
For instance, the amount of rainfall in City Upper B during April could be 0.10 inches of rain per hour, 0.30 inches of rain per hour. This numbers are not countable, they are rather approximated or rounded off.
Step-by-step explanation:
A random variable is considered discrete if its possible values are countable while a random variable is considered to be continuous if it's possible values are not countable.
Answer: 50 units squared
explanation: you just use the formula for area which is Length x height. The length would be 10 and the height would be 5. so we input it into the formula 5x10=50
Answer:
C they have equal x-intercepts
Step-by-step explanation:
Answer:
The numbers that work are: -15, 5, 3.5, and 4 3/4
Step-by-step explanation:
Subtract 5 from both sides of the equation. Which will give you 15≥3x. Then you divide both sides by 3 which will give you 5≥x.
20≥5+3x
<u>-5 -5</u>
15≥ 3x
<u>÷ 3 ÷ 3</u>
5 ≥ x
