Answer:
3.5
Step-by-step explanation:
the problem says 4.7 less than which refers to subtraction so we can plug our numbers into a subtraction problem like so
78.6-4.7 which equals 73.9
the second part of the problem asks the difference between yesterday's low and today's.
we can take the two lows and subtraction them to find this answer.
77.4-73.9 which equals 3.5
so today's low was 3.5 degrees cooler than yesturdays
If this was a triangle, the answer would be 35 degrees. Can you plz show a graph if you have one though?
Answer:
0.03
Step-by-step explanation:w
standard deviation = ( p(1-p) / n)1/2
p= sample proportion= 55%
n= sample size = 900
standard deviation = ( [55/100] [ 1- 55/100]) / 900)1/2
= (0.55*0.45 / 900)1/2
= 0.0165
margin of error = critical value*standard deviation
[ from graph critical value = 2]
margin of error = 2*0.0165=0.033
Answer:
c.They rank-order the units of analysis in terms of specific variables
Step-by-step explanation:
An index is a way of compiling one score from a variety of questions or statement that represents a belief, feeling or attitude.
Scales on the other hand measure levels of intensity at a variable level like how much a person agrees or disagrees with a particular statement.
The one thing common to both indexes and scales is that
They rank-order the units of analysis in terms of specific variables.
If its going by $11 for 2 hours then he babysat ?
ok so $11= 2 hours
11 x 3= 33 half of eleven is 5.5
so 33+ 5.5 = $38.50 so I believe the answer is 6 hours and 30 min but I'm not 100 percent positive
