Answer:
Data in this table are written in decimal numbers. That means that they don't present the number of students voting for their favorite sport, but portion of student from that grade. Another way to write decimal numbers is in percentages. For example 30% of students is 0.30, 48% is 0.48 etc.
Now that we know this, looking at the table we can see that the correct answer is C.
Answer:
To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
81,83,91,94
since its an even number add up the two middle numbers 83 and 91 to equal 174 then divide by two to have the median of 87
Step-by-step explanation:
The statement is always true.
Let's take -.12*-.5*.2
-.12*-.5*.2=.012
And:
-.2*-.4*.3=.024
A positive multiplied by a positive is, obviously, a positive.
The result of two negative numbers multiplying together is always positive.
So, negative*negative*positive is a positive answer.
Let's say that you're in your room and you find that the current temperature of 72 degrees is too cold, so slowly you increase the temperature of the room by two degrees.
We know that the explicit formula is
a^n=a^1+ (n-1)d
and so by substituting the given information in
a^n= 72 + (n-1)2
a^1=Initial temp
d= rate of change
by substitution a value of n (the term we are looking for) into this equation, you can then calculate the temperature that you just set the room too.
