Answer:
34.13%
Step-by-step explanation:
Given the mean score is 450 and the standard deviation is 120.
-The probability of scoring between 450 and 570 can be calculated as below:

Hence, 34.13% of the scores lies between 450 and 570
Answer:
Have the same vertex
, and be congruent.
Step-by-step explanation:
Simply because ideally, histogram is used in grouped
frequency parameters. Moreover, as little as the given five parameters or data
set this will be ineffective and will result to a bar graph only and basically,
the suited option is the aforementioned vertical graph to display the numbers. To
expound on the definition of histogram it is used when the frequency is
grouped. For example the data set of 1-5, 6-10, 11-15 and 16-20 this now can be
used and applied to illustrate histogram because of the number and quantity of
the given data.
Answer:
1. m<T =72 , m<U =54
2. EF= 18 in. , m<F=134'
3. x=4
Step-by-step explanation:
1. <s=<u , there is 180' in a triangle total so 180- <S - <U = <T
180 - 54 - 54 = 72
2. ef = gf
180 - 23 - 23 = 134
3. since bottom 2 angles are = , the 2 sides are also =

Answer:
x = s, y = t, z = 8 -s -t
Step-by-step explanation:
It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.
You could get more elaborate if you want:
x = 4-s, y = 4-t, z = s+t
