Yes
0:5
0:20
To get from 5 to 20 you multiply by 4 so what you do to one side, you do to the other so 0×4 is 0 so that gives you 0:20 which proves they are equivalent
1. the mean is 16
2. the mean is 22.5
the formula that can be used to calculate the mean is
= sum of terms/number of terms
for the first question the mean can be calculated as follows
sum of terms= 20+15+19+16+10
= 80
number of terms= 5
mean= 80/5
= 16
for the second question the mean can be calculated as follows
sum of terms= 19+23+11+30+27+27+22+26+16+24
= 225
number of terms= 10
mean= 225/10
= 22.5
Hence the mean for the first expression is 16 and the mean for the second expression is 22.5

P = 2(L + W)
P = 2(5+7)
P = 2(12)
P = 24
F=1.8C+32
We are given C=-20 degrees
plugging this value in the given equation
F=1.8(-20)+32
F=-36+32=-4
F=-4 degree fahrenheit
