The z-score is the number of standard deviations away from the mean. We first subtract the actual score from the mean, then divide the difference by the standard deviation. In this case, our actual score is 13, so we subtract from the mean of 16, then divide by the SD of 2
(13 - 16) / 2 = -1.5
Answer: 19.1842
Step-by-step explanation:
144+64= 178
a^2+b^2= c^2
Whenever finding a missing length use the formula up above :
a^2+b^2= c^2
a^2-b^2= c^2
144-64= 80
Answers are 13.3 and 8.9
Scale in terms of cm to m= 1/5
In every meter there are 5 cm
Considering this, if the dimensions are 15cm and 20cm, you would need to multiply them by 5 to convert them to meters
15*5= 75 20* 5=100
Dimensions- 75ft by 100ft
