We have the given in the problem as mentioned:
A total of 130 students and only 7 had been placed in the wrong math class.
With this given, we can easily draw the proportion of all students who have been placed in the wrong math class by estimation method and the solution is shown below:
Proportion = 7/130
Answer: 13
Step-by-step explanation:
4,7,13,18,32
cross out 4 and 32
7, 13, 18
cross out 7 and 18
13
there is your median
Step-by-step explanation:
W=-6, x=1.2, and z=-6/7
(W²x-3)÷10-z
we substitute
((-6²)(1.2)-3)÷10-(-6/7)
((-36)(1.2)-3) ÷10-(-6/7)
(-43.2-3) ÷10(6/7)
(-46.2)÷60/7
-46.2÷60/7
-46.2*7/60
-46.2/1*7/60
-323.4/60
-5.39
Making a list can help you solve a problem by:
•making more organized
•it can make it easier to organize data
•helps you stay on track
those are some of the basic ways,
