The score is given by:
z=(x-mean)/s.d
In the question above:
x=1300
mean=1200
s.d=200
Thus:
z=(1300-1200)/200
=100/200
=0.5
The answer is 0.5
B is the answer
Explanation b is the answer because I said so ;)
This is the last answer because if you reflect it 4 times over the x and y axis you will get back to the same spot
So I found the data for both sets of numbers.
It’ll go the first number is for set one, second number is for set two
Mean: 3, 2.909
Median: 3, 3
Quart: Q1- 2,1
Q2- 3,3
Q3- 4,5
Range: 6,5
SD: 1.73, 1.86
Mode: 3, 1
Hopefully this helps !
Answer:
142
Step-by-step explanation:
5*(x+60)+2*x=1294
5x+5*60+2x=1294
7x+300=1294
-300 -300
7x=994
x=994:7
x=142
