Answer:
To determine the probability of variances occurring, the appropriate statistic would be d) Chi-Square statistic.
x^2+y^2-18x-2y+82=64
Answer: 28
Step-by-step explanation:
To find the common denominator, you want to find the least common multiple of 4 and 7. The easiest way to do this is to multiply the denominators.
4*7=28
Therefore, the common denominator is 28.
The common denominator of the fractions 8/7 and 2/4 is 28. This is found by multiplying the original denominators together, as this resulting product can be evenly divided by both original denominators.
The question is asking for the common denominator of two fractions, 8/7 and 2/4. A common denominator is a number that both denominators can divide into evenly.
To find this, let's first look at the denominators of your two fractions. We have 7 and 4 as the denominators.
Start by multiplying these two numbers together to give 28. Indeed, both 7 and 4 can divide into 28 evenly (7*4=28, 4*7=28) so, 28 is a common denominator for these two fractions.
Therefore, the common denominator of 8/7 and 2/4 is 28.

Answer:
164 tiles
Step-by-step explanation:
Per the above details, we will require tiles along all the sides of the swimming pool ,hence the circumference of the pool is denoted as;
= 2(wide + long)
Wide = 30 feet
Long = 50 feet
Circumference = 2(30 + 50)
Circumference = 2(80)
Circumference = 160.
It means that minimum of 160 tiles of 1 ft length is required, however, we will also require tile on each of the corners(4), total equals
= 160 + 4
= 164 tiles
A total of 164 tiles are there surrounding the pool.
Just substitute..
y=3x for X
y=3(-1)
y=3(0)
y=3(1)
y=3(2)
y=3(3)
then what you get for y just plot it
