Answer:
Yes, there is one outlier (lower)
Step-by-step explanation:
Looking at the distribution of the lower/smallest observation, we can see that there is a values in the lower/smallest that is very far from others. See the attached box-plot for understanding.
The median is the line in the middle of the box-plot.
The Lower fourth is the lower whisker line and upper fourth is the upper whisker line. The lower box (just below the median) line is the 1st quartile and the upper box line (just above the median) is 3rd quartile.
Answer:
x=7.5
Step-by-step explanation:
Let's solve your equation step-by-step.
3(x+4.5)=36
Step 1: Simplify both sides of the equation.
3(x+4.5)=36
(3)(x)+(3)(4.5)=36(Distribute)
3x+13.5=36
Step 2: Subtract 13.5 from both sides.
3x+13.5−13.5=36−13.5
3x=22.5
Step 3: Divide both sides by 3.
3x/3=22.5/3
x=7.5
Answer:
x=7.5
√42 is an irrational number, because you cannot express the answer as a fraction (ratio), and it certainly isn't a whole number or an integer.
Answer: 373/50
Step-by-step explanation:
Step 1: convert to a fraction
746% = 746 ÷ 100 = 7.46
7.46 = 373/50
Step 2: Write the number as a fraction of one: 7.46 = 746/100
Step 3: use a common divisor of 2 to reduce the numbers, we have
(746÷2)= 373
(100÷2)=50
when reduced to the simplest form= 373/50
Therefore, 746/ 100 = 373/50 when expressed as a mixed number.
Answer:
The three consecutive integers are 12, 13, 14.
Step-by-step explanation:
Encode the question in an equation. We are given two facts: (1) the three integers are consecutive, and (2) they relate to each other through a sum.
Pick any of the integers (first, second, or third) and call it n. Then write the two others correspondingly in terms of n. I pick the middle one as n, so the three consecutive integers are (n-1), n, (n+1). That's (1). As for (2), here is the fact:
Lo and behold, one equation with one unknown! Easy to solve for n to give us the middle integer, n:
The three consecutive integers are 12, 13, 14.
