Answer:
497
Step-by-step explanation:
If x ≥ 5, we round up.
If x < 5, we round down.
Since 7 ≥ 5, we round 496.739386253 to 497.
Answer:
467
Step-by-step explanation:
7 is greater than 5 so the six is rounded to a 7

Answer:
2/3 ≈ 0.666667
5/11 ≈ 0.454545
5/6 ≈ 0.833333
6/7 ≈ 0.857143
Step-by-step explanation:
Easiest and fastest way to do this is to use a calculator to find your decimals and then approximate.
Answer:
2/3 = 2 divided by 3 so 2 divided by 3 = 0.666667. We round up because it is a repeating decimal which goes on forever
5/11= 5 divided by 11 = 0.454545
5/6 = 5 divided by 6 =0.833333
6/7 = 6 divided by 7 = 0.857143
rounded up because it is an infinite decimal
Hope this helps

Answer: 1) Percentage, Probability, Proportion
Step-by-step explanation:
In statistics,
▪Proportion means a fraction of the total.
▪Percentage means a number or a ratio, expressed as a fraction of 100. Here, the total is 100.
▪Probability which may look slightly different from the other two means a number between 0 and 1, showing the exact likelihood of an event happening. Which in context can mean, a number showing a fraction of an event happening out of the whole (0 to 1).
▪Critical value means a point in hypothesis testing on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis.
In the four definitions, the odd one out is Critical Value.
So the option without critical value in it is option 1) Percentage, Probability, Proportion since we can use the three interchangeable.
Answer:
1. Percentage, Probability, and Proportion
Step-by-step explanation:
Proportion means a portion of a whole e.g. 2/5
Percentage means a ratio of a number expressed as a fraction of 100 e.g 20/100
Probability- This means the likelihood of an event to occur e.g 1/2
All these three terms are usually expressed as a Fraction of a Number which makes them similar.
Answer:
Yes it's a function.
Step-by-step explanation:
To know if it's a function check if there is two x-intercepts. If there is them it's not a if there isn't then, it's a function.

Answer:
Width of the rectangle is (x-5)
Step-by-step explanation:
We know that, the product of length and width gives the area of the rectangle.
The area of a rectangle is given as,
Factoring the area,
Putting it in the equation,
A clue that would help to find the speed of the current is that the rate of Chan's rowing in still water is 8 mph.
This concept comprises of 4 terminologies:
Given:
Speed of Chan's boat in stillwater = 8 mph
Time taken by Chan to row upstream from his house to the park = 3 h
Time taken by Chan to row downstream from the park to his house = 2 h
we have to find the speed of the current.
Let the speed of the current be v.
We know, Speed = Distance / Time
⇒ Distance = Speed × Time
Now, the distance between the house and the park is constant, hence the distance travelled upstream and downstream will be constant.
For upstream, speed of the boat is calculated as:
⇒ Speed = (speed of the boat in still water) - (speed of the current)
⇒ Speed = (8 - v)
Hence, distance is:
⇒ Distance = (8 - v) × 3 …(1)
Similarly for downstream, speed of the boat is:
⇒ Speed = (speed of the boat in still water) + (speed of the current)
⇒ Speed = (8 + v)
Distance will be:
⇒ Distance = (8 + v) × 2 …(2)
Now since the distance is equal we can equate the equation (1) and (2).
⇒ (8 - v) × 3 = (8 + v) × 2
⇒ 24 - 3v = 16 + 2v
⇒ 5v = 8
⇒ v = 1.6 mph
Hence, the speed of the current is 1.6 mph.
Here, we can observe that to solve this problem we need the time taken to cross along each stream and the speed of the boat in the still water.
The option: Chan rows from house to the park on Wednesday, gives information about the the distance travelled by the boat and it is constant and cannot be used to deduce the speed of the current.
The option: The entire trip takes five hours, is not used anywhere to solve the problem, instead the separate times to cross each stream was required. Hence this option was also not sufficient.
Therefore, the rate of Chan's rowing in still water is 8 mph, is the clue that helps to solve this word problem.
