Evaluate: 30 - 12÷3×2 =
lara [203]

Answer:

22

Step-by-step explanation:

We can use the order of operations (PEMDAS), to solve this equation.

We must first multiply and divide, and order. This means we divide 12 by 3 and get 4, then multiply that by 2 and get 8. (30-12÷3×2,30-4×2,30-8). Now we just subtract 8 from 30 and get 22 as our answer.

What type of graph organizes data into 4 groups of equal size, and is often used to compare two sets of data.
aliina [53]

The plot that organizes the data into 4 groups of equal sizes is box and whisker plot.

The image below shows a box and whisker plot. Following are the elements of box and whisker plot:

Minimum = This is the smallest value of the data set

Q1 = First (Lower) Quartile of the data set. 25% of the data values lie below this point

Q2 = Second Quartile or Median. This is the central value so 50% of the data values lie below this point

Q3 = Third (Upper) Quartile of the data set. 75% of the data values lie below this point.

Maximum = This is the maximum value of the data set.

Based on box and whisker plot we can compare two or more sets of data by comparing the spread of the data. We can also directly observe from the box and whisker plot if the data is uniform, normal or skewed. Using box and whisker plot we can also visualize any outliers that may be in the data.

What is the solution to the proportion 3y-8/12=y/5? can someone help me do this?
RideAnS [48]
   
\displaystyle\\
 \frac{3y-8}{12} = \frac{y}{5}  \\  \\ 
5(3y-8)=12y\\\\
15y-40=12y\\\\
3y = 40\\\\
\boxed{y =  \frac{40}{3}}
