Equation of 2x-y= 5 where we know the y value from (x,1)
We substitute the y value in the equation to get the x value easily
2x-1= 5
2x = 5 + 1
2x = 6
x = 3 (divide both side by 2)
Answer x = 3 when y = 1
Round 57.8 to 60 and round 81 to 80.
60/80 or, if you simplify it, 3/4
And it is common knowledge that 3/4 = .75
So the quotient of 57.8/81 is ~.75
Answer:
The data is skewed to the bottom and contains an outlier.
Step-by-step explanation:
1. Test for outlier
An outlier is a point that is more than 1.5IQR below Q1 or above Q3.
IQR = Q3 - Q1 = 74 - 51 = 23
1.5 IQR = 1.5 × 23 = 34.5
51 - 15 = 36 > 1.5IQR
The point at 15 is an outlier.
2. Test for normal distribution
The median is not in the middle of the box.
Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.
3. Test for skewness
The longer part is to the left of the median, so the data is skewed left.
Answer:
a. There are 48 angelfish.
b. There are 36 goldfish.
Step-by-step explanation:
the ration of clownfish to angelfish is 5:4 and there are 60 clownfish.
60:? 5x=60 x=12 12(4)=48
60:48 there are 48 angelfish
the ration of angelfish to goldfish is 4:3 and know we know there are 48 angelfish
48:? 4x=48 x=12 12(3)=36
48:36 there are 36 goldfish
Answer:
I think it's rational number
