The answer :
4/5
Step-by-step explanation:
4x-5y=0
subtract 4x on both the sides
4x-4x-5y = 0-4x
-5y = -4x
divide by -5 on both the sides
-5y/-5 = -4x/-5
y =( 4/5 )x
0.161 (they said explain it so)
Answer:
Well for Part A-
List the temperatures from least to greatest; anything under 0 degrees is the lowest.
-6.1
-2.5
-0.4
3.4
And for Part B-
You can use a number line to order the temperatures because it's a good way to sort which ones are the lowest and highest easily.
The probability that x >17 will be found as follows:
the z-score is given by:
z=(17-15.2)/0.9=2
Thus
P(X>17)=1-P(x<17)=P-(z=2)
=1-0.9772
=0.0228
